The Complete UK Payroll Guide for Company Directors 2025/26

If you run a UK limited company, payroll is not optional. The moment you pay yourself a salary, even a small one, you become an employer in the eyes of HMRC. That means registering for PAYE, running Real Time Information (RTI) submissions, calculating National Insurance correctly, and meeting a calendar of deadlines that carry real penalties if you miss them.

Yet payroll is also where some of the biggest tax savings live. The difference between a well-structured salary and dividend combination and a naive approach can be thousands of pounds per year. Get your payroll strategy right and you keep more of what you earn. Get it wrong and you hand unnecessary money to HMRC while potentially exposing yourself to penalties.

This guide is written specifically for directors of UK limited companies with between one and five employees, though much of the advice applies to any small company payroll. We cover every aspect of director payroll for the 2025/26 tax year (6 April 2025 to 5 April 2026): setting up PAYE, choosing your optimal salary, understanding National Insurance, the salary vs dividends decision, pension strategies, benefits in kind, employing others, dividend mechanics, and staying compliant.

Each section includes specific 2025/26 rates, thresholds, and worked examples with real numbers. Where topics overlap with our other guides, we link to the detailed treatment. If you are also looking for broader tax guidance, read our complete limited company tax guide alongside this one.

Before you can pay yourself or anyone else a salary through your limited company, you must register as an employer with HMRC and set up Pay As You Earn (PAYE). This is the system through which income tax and National Insurance are collected on employment income. Registration is free and straightforward, but there are important timing requirements you need to know.

When to Register

You must register as an employer before your first payday. HMRC recommends registering at least two weeks before you intend to make your first salary payment, because it can take up to 10 working days to receive your PAYE reference numbers. If you are incorporating a new company and plan to pay yourself immediately, start the registration process as soon as the company is formed.

You do not need to register for PAYE if:

• None of your employees (including you) are paid above the Lower Earnings Limit (currently 6,396 per year for 2025/26)
• No employees have another job or receive a pension
• No employees receive expenses or benefits

However, in practice, most directors paying themselves any salary above a nominal amount should register. Even if your salary is below the income tax and NI thresholds, having PAYE in place ensures you are submitting RTI returns and building State Pension qualifying years.

How to Register

Registration is done online through the HMRC website. You will need your company's Unique Taxpayer Reference (UTR), which you received when your company was formed, and your company's registered address. The process involves:

1. Sign in to your HMRC business tax account (or create one using your Government Gateway credentials)
2. Select "Register as an employer" and follow the prompts. You will provide details about your company, the expected number of employees, and your first payday.
3. Receive your PAYE reference numbers. HMRC will send you two key reference numbers by post: your Employer PAYE Reference (format: 123/AB45678) and your Accounts Office Reference (format: 123PA00012345). You need both to submit RTI returns and make payments to HMRC.
4. Set up payroll software. Once registered, you need software to run payroll and submit RTI. HMRC provides free Basic PAYE Tools (BPT) for employers with fewer than 10 employees. Commercial alternatives include FreeAgent, Xero, Sage, and dedicated payroll services.

HMRC Basic PAYE Tools

For most single-director companies, HMRC's Basic PAYE Tools (BPT) is sufficient. It is free, handles RTI submissions directly to HMRC, calculates tax and NI correctly (including the director's annual earnings period method), and generates payslips and year-end documents. The main limitations are its basic interface and lack of integration with accounting software. For our detailed walkthrough, see our PAYE for directors guide.

Your First Payroll Run

Once registered and set up, your first payroll run involves:

• Entering your details as a director (including your tax code, which is typically 1257L for 2025/26)
• Selecting the director status for NI calculation purposes (this triggers the annual earnings period method rather than the standard cumulative method)
• Processing your salary payment and reviewing the calculated tax and NI deductions
• Submitting the Full Payment Submission (FPS) to HMRC on or before your payday
• Paying HMRC any tax and NI owed by the 22nd of the following month (or 19th if paying by post)

Choosing the right salary level is the single most impactful payroll decision you make each year. The goal is to balance tax efficiency with State Pension entitlement, mortgage eligibility, and pension contribution capacity. For the 2025/26 tax year, there are two commonly discussed salary levels, each with different trade-offs.

Option A: 12,570 (The Personal Allowance)

Setting your salary at 12,570 per year (1,047.50 per month) uses your full personal allowance, meaning you pay zero income tax on your salary. You also build a full qualifying year for State Pension purposes. However, you will pay employer National Insurance on the portion above the secondary threshold of 5,000.

The costs at this salary level:

• Income tax: 0 (salary equals the personal allowance)
• Employee NI: 0 (salary is at the primary threshold of 12,570, so no employee NI is due)
• Employer NI: (12,570 - 5,000) x 15% = 1,136
• Corporation Tax saving: The salary plus employer NI (13,706 total) is deductible, saving 13,706 x 19% = 2,604 in CT
• Net benefit of paying 12,570 vs 5,000: The additional 7,570 salary costs 1,136 in employer NI but saves 1,438 in Corporation Tax (at 19%), a net saving of approximately 302

Option B: 5,000 (Below Secondary NI Threshold)

Setting your salary at 5,000 per year (416.67 per month) keeps you below the employer NI secondary threshold, meaning zero National Insurance is payable by either you or the company. The salary is below the personal allowance so no income tax applies either.

The costs at this salary level:

• Income tax: 0
• Employee NI: 0
• Employer NI: 0
• Corporation Tax saving: 5,000 x 19% = 950

State Pension risk: At 5,000, your earnings are below the Lower Earnings Limit of 6,396 for 2025/26. This means the year may not count as a qualifying year for your State Pension unless you also have other qualifying income. If you only have income from your company, you would need at least 6,396 in salary (or to pay voluntary Class 3 NI contributions at 17.45 per week) to secure a qualifying year.

The Employment Allowance Factor

If your company qualifies for the Employment Allowance (up to 10,500 for 2025/26), the calculation changes dramatically. The Employment Allowance offsets your employer NI bill, which means the 1,136 employer NI cost at the 12,570 salary level is effectively eliminated.

You qualify for Employment Allowance if your company had an employer NI bill of less than 100,000 in the previous tax year and you are not a single-director company with no other employees. If you employ your spouse, even part-time, you become eligible. In that scenario, a salary of 12,570 is almost always the better choice.

Our Recommendation

For most single-director companies without Employment Allowance: set your salary at 12,570. The net cost difference compared to 5,000 is modest (approximately 302 per year after CT relief), and you gain a full State Pension qualifying year, higher declared income for mortgage applications, and a larger base for personal pension contributions. See our director's salary guide for 2025/26 for the full analysis including edge cases.

National Insurance for company directors works differently from NI for ordinary employees. Understanding these differences is essential to calculating your payroll correctly and avoiding either overpaying or underpaying HMRC.

The Annual Earnings Period Method

Most employees have their NI calculated on a per-pay-period basis. If you are paid monthly, each month's earnings are assessed against monthly thresholds independently. Directors, however, are assessed using the annual earnings period (AEP) method. This means NI is calculated on your cumulative earnings for the entire tax year, compared against annual thresholds.

In practice, this means a director who pays themselves a lump sum at year end is treated identically to one who pays evenly across 12 months, as long as the annual total is the same. Your payroll software should automatically apply the director's annual method when you flag yourself as a director, but it is important to verify this is set up correctly. An alternative cumulative method exists where NI is calculated cumulatively through the year and then trued up in month 12, but the result is mathematically identical.

Employee NI (Class 1 Primary)

As a director earning a salary, you pay employee NI at 8% on annual earnings between 12,570 (the Primary Threshold, aligned with the personal allowance) and 50,270 (the Upper Earnings Limit). On earnings above 50,270, the rate drops to 2%. If your salary is set at the optimal 12,570, your employee NI liability is zero because your earnings are at (not above) the Primary Threshold.

Employer NI (Class 1 Secondary)

Your company pays employer NI at 15% on your annual earnings above the Secondary Threshold of 5,000. This threshold dropped significantly from 9,100 in the 2024/25 tax year, increasing the employer NI cost for all directors. There is no upper limit on employer NI; it applies at 15% on all earnings above 5,000 regardless of how high the salary goes.

Employer NI is a deductible business expense for Corporation Tax purposes. So while you pay 15% in NI, you save 19% (or more in the marginal band) of that amount in CT. The net cost of each pound of employer NI is therefore approximately 81p after the CT deduction.

Employment Allowance (10,500)

The Employment Allowance lets eligible employers offset up to 10,500 against their employer NI bill each year. This is a significant benefit. However, single-director companies with no other employees are not eligible. You qualify if:

• Your company has at least one other employee (even part-time)
• Your total employer NI bill in the previous year was under 100,000
• You are not a public body or carrying out more than half your work as a public body

If you employ your spouse part-time for genuine work, this alone makes you eligible. The 10,500 allowance would typically wipe out all employer NI for a small company, making the 12,570 salary level even more attractive because the employer NI cost disappears entirely. For the full details, see our National Insurance guide for directors.

Worked Example: NI on a 12,570 Salary

A sole director pays themselves 12,570 per year. No Employment Allowance is available (no other employees).

• Employee NI: 12,570 is at the Primary Threshold, so employee NI = 0
• Employer NI: (12,570 - 5,000) x 15% = 7,570 x 0.15 = 1,135.50
• Total NI cost: 1,135.50 (all borne by the company)
• CT saving on employer NI: 1,135.50 x 19% = 215.75
• Net employer NI cost: 1,135.50 - 215.75 = 919.75

The salary vs dividend question is at the heart of every director's tax planning. Salary is subject to income tax and National Insurance but is deductible for Corporation Tax. Dividends avoid NI entirely but are paid from profits that have already been taxed at the Corporation Tax rate. The optimal split depends on your profit level and personal circumstances.

Tax Rates Comparison for 2025/26

Worked Example: 50,000 Company Profit

Your company has 50,000 in profit before your salary. Using the optimal strategy:

1. Pay salary of 12,570. Income tax = 0. Employee NI = 0. Employer NI = (12,570 - 5,000) x 15% = 1,136. Remaining company profit = 50,000 - 12,570 - 1,136 = 36,294.
2. Corporation Tax at 19% on 36,294 = 6,896.
3. Available for dividends: 36,294 - 6,896 = 29,398.
4. Dividend tax: First 500 at 0% = 0. Remaining 28,898 at 8.75% = 2,529.
5. Total take-home: 12,570 (salary) + 29,398 (dividends) - 2,529 (dividend tax) = 39,439.
6. Effective tax rate: 21.1% on 50,000 of company profit.

Worked Example: 100,000 Company Profit

Your company has 100,000 in profit before your salary:

1. Pay salary of 12,570. Employer NI = 1,136. Remaining company profit = 86,294.
2. Corporation Tax at 19% (below 50,000 threshold after deductions): actually, 86,294 is in the marginal relief band (50,001-250,000), so the effective rate is higher. Corporation Tax = approximately 18,400.
3. Available for dividends: 86,294 - 18,400 = 67,894.
4. Dividend tax: First 500 at 0% = 0. Next 37,200 at 8.75% (using remaining basic rate band: 50,270 - 12,570 - 500 = 37,200) = 3,255. Remaining 30,194 at 33.75% (higher rate) = 10,190.
5. Total take-home: 12,570 + 67,894 - 13,445 = 67,019.
6. Effective tax rate: 33.0% on 100,000 of company profit.

Worked Example: 200,000 Company Profit

At 200,000 in profit, the higher rate dividend tax bite becomes substantial:

1. Pay salary of 12,570. Employer NI = 1,136. Remaining company profit = 186,294.
2. Corporation Tax at marginal rate: approximately 43,700.
3. Available for dividends: 186,294 - 43,700 = 142,594.
4. Dividend tax: Mix of basic rate (8.75%) and higher rate (33.75%) and additional rate (39.35%). Approximately 40,700 in total dividend tax.
5. Total take-home: approximately 114,464.
6. Effective tax rate: 42.8%.

At this profit level, pension contributions become particularly valuable because they reduce profit before Corporation Tax and avoid all personal taxation. A 40,000 employer pension contribution at this level saves approximately 16,000 in combined tax. See our detailed salary vs dividends guide for more scenarios and edge cases.

When Higher Salary Makes Sense

Despite the general rule of low salary plus dividends, there are situations where a higher salary is justified:

• Mortgage applications: Lenders typically weight salary income more heavily than dividends. A higher salary can increase your borrowing capacity significantly.
• Maternity/paternity benefits: Statutory maternity pay is based on average weekly earnings. A higher salary qualifies you for higher SMP.
• Employment Allowance available: If the employer NI is offset by the 10,500 allowance, higher salary has a lower marginal cost.
• Pension qualifying earnings: If you want to make personal (not employer) pension contributions, your relevant UK earnings must at least equal the contribution amount.

Pension contributions are one of the most powerful tools in a director's tax planning arsenal. When structured as employer contributions through your company, they reduce Corporation Tax, avoid all National Insurance, and are not treated as personal income. This makes them the most tax-efficient way to extract profit from your company after the optimal salary.

Employer Contributions: The Preferred Route

When your limited company makes an employer pension contribution on your behalf, the following tax treatment applies:

• Corporation Tax deductible: The contribution reduces your company's taxable profit, saving 19% (or up to 26.5% in the marginal band) of the contribution amount
• No employer NI: Unlike salary, there is no 15% employer NI charge on pension contributions
• No employee NI: The contribution is not treated as earnings for NI purposes
• No income tax: The contribution is not personal income at the point of payment

Compare this with taking an additional 10,000 as salary (which would cost 20% income tax + 8% employee NI + 15% employer NI = 43% in combined taxes at the basic rate) or as dividends (19% CT + 8.75% dividend tax = approximately 26% combined). A 10,000 employer pension contribution costs just the 19% Corporation Tax the company would otherwise have paid, saving 8,100 that reaches your pension versus approximately 5,700 that would reach your bank account as salary.

Personal Contributions

You can also make personal contributions from your after-tax income. The pension provider claims basic rate (20%) tax relief automatically, and if you are a higher rate taxpayer, you claim the additional 20% relief through your Self Assessment return. However, personal contributions do not save Corporation Tax or NI, making them less efficient than employer contributions in most cases.

Personal contributions are limited by your relevant UK earnings for the year. If your salary is 12,570, your maximum personal contribution with tax relief is 12,570. Employer contributions do not have this restriction.

Annual Allowance (60,000)

The total contributions from all sources (employer + personal) in a tax year cannot exceed 60,000 or 100% of your UK earnings, whichever is lower. However, unused allowance from the previous three tax years can be carried forward, potentially allowing much larger one-off contributions.

Tapered Annual Allowance

If your adjusted income (total income including employer pension contributions) exceeds 260,000, the annual allowance reduces by 1 for every 2 of excess, down to a minimum of 10,000 (at adjusted income of 360,000 or above). Most micro-business directors will not hit this taper, but it is worth checking if you have significant income from other sources.

Auto-Enrolment Obligations

If you are a sole director with no other employees, you are exempt from auto-enrolment duties. However, if you have even one other employee, you must:

• Assess all eligible workers (including yourself) for auto-enrolment
• Set up a qualifying workplace pension scheme
• Make minimum employer contributions of 3% of qualifying earnings (between 6,240 and 50,270 for 2025/26)
• Submit a Declaration of Compliance to The Pensions Regulator

Salary Sacrifice Arrangements

Under salary sacrifice, you agree to reduce your contractual salary in exchange for the company making a larger employer pension contribution. The benefit is that both employer and employee NI are saved on the sacrificed amount. For a director earning above the NI thresholds, this can save an additional 23% (8% employee NI + 15% employer NI) on the sacrificed portion. The company can pass some or all of the employer NI saving into the pension contribution as well.

For the complete analysis, including carry-forward strategies and timing considerations, see our pension contributions guide for limited companies.

Benefits in Kind (BiKs) are non-cash benefits that your company provides to you as a director or to your employees. They are generally taxable as if they were additional salary, and must be reported to HMRC. Understanding which benefits are taxable and how to report them correctly is essential for payroll compliance.

P11D Reporting

Most benefits in kind must be reported on a P11D form, submitted to HMRC by 6 July following the end of the tax year. The company also pays Class 1A NI at 15% on the total value of benefits reported on the P11D, due by 22 July. The director pays income tax on the benefit value through their Self Assessment return or via a PAYE code adjustment.

Common Benefits in Kind

Company Cars: The taxable benefit is based on the car's list price multiplied by a percentage determined by its CO2 emissions. Electric vehicles currently attract the lowest rate (2% for 2025/26), making them highly tax-efficient. A company car with a 40,000 list price and 2% BiK rate creates a taxable benefit of just 800 per year. Our P11D guide covers the full calculation.

Private Medical Insurance: The premium your company pays becomes a taxable benefit. However, the premium is a deductible company expense for Corporation Tax. If the company pays 1,200 per year, the director pays income tax on 1,200 (approximately 240 at basic rate) and the company pays Class 1A NI of 180. The net cost is typically lower than buying the insurance personally.

Beneficial Loans: If the company lends you more than 10,000 at below the official interest rate (currently 2.25%), the difference is a taxable benefit. This often arises with director's loan accounts. See our director's loan account guide for the implications.

Mobile Phones: One mobile phone per employee is exempt from tax and NI, regardless of the cost of the phone or contract, provided the contract is in the company's name. This is a genuinely free benefit with no BiK charge.

Trivial Benefits (50 Rule)

Small benefits costing 50 or less per occasion are exempt from tax and NI reporting, provided they:

• Are not cash or cash vouchers
• Are not a reward for work or performance
• Are not part of a contractual entitlement
• Cost the employer no more than 50 (including VAT)

For directors and other office holders, there is an additional annual cap of 300 in total trivial benefits per tax year. This is a useful way to provide small perks like birthday gifts, hampers, or event tickets without creating a tax liability. See our trivial benefits guide for the full rules and examples.

Payrolling Benefits

Instead of reporting benefits on the P11D, you can choose to payroll benefits. This means the taxable value of the benefit is added to the employee's pay for tax purposes each pay period, and the tax is collected through PAYE in real time. You must register with HMRC to payroll benefits before the start of the tax year. The advantage is simpler year-end administration (no P11D required for payrolled benefits), though you still need to report Class 1A NI.

When you take on your first employee beyond yourself, your payroll obligations increase. You gain access to the Employment Allowance, but you also take on auto-enrolment duties, more complex RTI submissions, and employment law responsibilities. This section covers the key considerations for micro-business directors hiring their first employees.

Employing Your Spouse

Employing your spouse or partner is one of the most common and tax-efficient strategies for small company directors. When done correctly, it allows you to:

• Use a second personal allowance: Your spouse can earn up to 12,570 tax-free, extracting an additional 12,570 from the company with no income tax cost
• Qualify for Employment Allowance: Having a second employee (even part-time) makes your company eligible for up to 10,500 in employer NI relief
• Build their State Pension: Even a modest salary above the Lower Earnings Limit builds qualifying years
• Provide pension contributions: Your company can make employer pension contributions on their behalf, further reducing your CT bill

Critical requirement: Your spouse must perform genuine work for the company, and the salary must be commercially reasonable for that work. HMRC can challenge arrangements where the salary is disproportionate to the work done. Common legitimate roles include bookkeeping, office administration, customer service, social media management, and marketing. Keep records of hours worked and duties performed. See our guide to employing your spouse for the detailed rules, and our guide to employing family members for broader family employment considerations.

Hiring Non-Family Employees

When you hire employees beyond family members, additional obligations apply:

• Employment contracts: You must provide a written statement of employment particulars from day one
• Right to work checks: Verify every employee's right to work in the UK before they start
• Employer's liability insurance:Mandatory if you have any employees. Failure to have it is a criminal offence with fines of up to 2,500 per day
• Workplace pension: Auto-enrolment duties apply for eligible workers
• Health and safety: You have a duty of care to all employees

RTI Submissions with Multiple Employees

With multiple employees, each payday requires a Full Payment Submission (FPS) that includes details for every employee paid that period. You must report each employee's gross pay, tax deducted, NI contributions, and any statutory payments (SSP, SMP, etc.). Each employee needs their own tax code, and you are responsible for applying the correct code to their pay calculations.

Auto-Enrolment Duties

Once you have any employees other than yourself as sole director, you must assess all workers for automatic enrolment into a workplace pension. Eligible workers are those aged between 22 and State Pension age, earning above the earnings trigger of 10,000 per year, and working in the UK. For eligible workers, the minimum contributions for 2025/26 are:

• Employer minimum: 3% of qualifying earnings (between 6,240 and 50,270)
• Total minimum: 8% of qualifying earnings (employer + employee combined)

Dividends are the primary way most limited company directors extract profit beyond their salary. Unlike salary, dividends are not subject to National Insurance, making them more tax-efficient for income within the basic rate band. However, there are strict rules about when and how dividends can be declared, and getting this wrong can have serious consequences.

How to Declare Dividends Properly

Every dividend payment should follow a formal process, even in a single-director company:

1. Check available profits. You can only declare dividends from accumulated realised profits less accumulated realised losses. This is your cumulative retained profit, not just the current year's profit. If your company has losses carried forward from previous years, these reduce the amount available for distribution.
2. Hold a board meeting (even if you are the sole director) and record the decision to declare a dividend in the minutes. The minutes should state the total dividend amount, the date of payment, and the shareholders entitled to receive it.
3. Issue a dividend voucher for each shareholder. The voucher should include the company name, date of payment, shareholder name, and the amount. While not strictly required by law, dividend vouchers are essential evidence for your tax records and HMRC may request them during an enquiry.
4. Make the payment. Transfer the dividend amount from the company bank account to the shareholder's personal account. The payment date determines which tax year the dividend falls into for personal tax purposes.

Dividend Tax Rates for 2025/26

The 500 Dividend Allowance

The first 500 of dividend income each year is tax-free, regardless of which tax band it falls into. This allowance was 1,000 in 2023/24, reduced to 500 from April 2024 onwards. It applies per individual, not per company, so if you receive dividends from multiple sources, the total 500 allowance is shared across all of them.

Illegal Dividends

Dividends declared when the company does not have sufficient accumulated realised profits are known as illegal or unlawful dividends. The consequences can be severe:

• You may be required to repay the dividend to the company
• HMRC may reclassify the payment as a director's loan, triggering a Section 455 tax charge of 33.75% if not repaid within 9 months of year end
• In extreme cases, HMRC could treat the payment as disguised remuneration, subject to full income tax and NI

Always check your company's accumulated profit position before declaring dividends. If you are unsure, produce management accounts showing retained profits to date. For more detail, see our guide to illegal dividends.

Dividend Timing Strategy

Dividends are taxed in the personal tax year (6 April to 5 April) in which they are paid, not declared. This gives you flexibility to manage which tax year the income falls into. Key timing considerations include:

• Stay within the basic rate band: If you are approaching the 50,270 threshold (salary + dividends), consider deferring additional dividends to the next tax year
• Use the full dividend allowance: Make sure you take at least 500 in dividends each year to use the tax-free allowance
• Interim vs final dividends: You can declare interim dividends at any time during the year without waiting for year-end accounts. Final dividends are declared at the annual general meeting.

For a complete treatment of timing strategies, read our dividend timing strategy guide.

Running payroll is not a one-off setup task. It involves ongoing compliance obligations throughout the year and specific year-end procedures. Missing deadlines attracts automatic penalties from HMRC, so understanding the compliance calendar is essential.

Real Time Information (RTI)

RTI is the system through which you report payroll information to HMRC. There are two main submission types:

Full Payment Submission (FPS): You must submit an FPS on or before every payday. It includes details of each employee's gross pay, tax deducted, NI contributions, student loan deductions, and any statutory payments for that pay period. For a monthly payroll, you submit 12 FPS per year.

Employer Payment Summary (EPS): Submit an EPS if you need to claim Employment Allowance, report no payments in a tax month, recover statutory payments (SMP, SSP, etc.), or claim the NI holiday for under-21s or apprentices under 25. The EPS must be submitted by the 19th of the month following the tax month.

Payment Deadlines

Late Filing Penalties

HMRC charges automatic penalties for late FPS submissions. For employers with 1-9 employees, the penalty is 100 per month for each month (or part month) that the FPS is late. HMRC allows one late FPS per tax year without penalty (a "free pass"), but from the second offence onwards, penalties apply. These penalties are charged quarterly.

Year-End Procedures

At the end of each tax year (5 April), you must complete several year-end tasks:

1. Submit the final FPS with the "final submission" indicator ticked. This tells HMRC your payroll for the year is complete.
2. Issue P60s to all employees who were on your payroll at 5 April. The P60 summarises their total pay, tax, and NI for the year. The deadline is 31 May.
3. Submit P11D forms if you provided any benefits in kind that were not payrolled. The deadline is 6 July.
4. Pay Class 1A NI on reported benefits by 22 July (or 19 July if paying by post).
5. Update payroll software for the new tax year, ensuring new tax codes, NI thresholds, and rates are applied from 6 April.

HMRC Basic PAYE Tools vs Commercial Software

For a single-director company or one with just a few employees, HMRC's free Basic PAYE Tools handles all compliance requirements. The main advantage of commercial payroll software is automation (auto-submission, email payslips, accounting integration) and a more user-friendly interface. The compliance outcome is identical because all software must calculate tax and NI using the same HMRC rules.

These are the payroll mistakes we see most frequently among UK limited company directors. Each one is avoidable with the right knowledge and basic planning.

1. Not Registering for PAYE

Some directors pay themselves a salary without registering as an employer. HMRC considers this non-compliance, and when discovered, you will be required to register retrospectively, file all missed RTI submissions, and pay any outstanding tax and NI plus interest and penalties. Register before your first payday, no exceptions.

2. Missing RTI Deadlines

The FPS must be submitted on or before each payday. Many directors who pay themselves monthly forget to submit or assume it can wait until the end of the quarter. Each late FPS attracts a penalty of 100 per month for small employers. Set a calendar reminder or use payroll software with automatic submission.

3. Taking Salary Above the Optimal Level

Directors who pay themselves 40,000 or 50,000 in salary without considering the NI implications are significantly over-taxed. A salary of 50,000 incurs approximately 2,994 in employee NI and 6,750 in employer NI, compared to zero employee NI and 1,136 employer NI at the 12,570 level. The additional 37,430 is far more efficiently extracted as dividends.

4. Forgetting Employer NI is a Separate Cost

Employer NI is paid by the company on top of the gross salary. If you budget to pay yourself 12,570, the total cost to the company is 12,570 plus 1,136 in employer NI = 13,706. Many directors forget to account for this additional cost in their cash flow planning.

5. Not Flagging Director Status in Payroll Software

Directors must be flagged in payroll software so the annual earnings period method is used for NI calculations. Using the standard cumulative method for regular employees can result in incorrect NI calculations, particularly if you pay yourself irregular amounts throughout the year (such as a large bonus in one month).

6. Ignoring the Employment Allowance Opportunity

Single-director companies miss out on up to 10,500 in employer NI relief simply because they have no other employees. Employing a spouse or family member for genuine part-time work can unlock this allowance, often saving more in NI than the additional salary costs.

7. Paying Dividends Without Board Minutes

Taking money from the company without proper dividend documentation creates risk. If HMRC enquires and you cannot produce board minutes and dividend vouchers, they may reclassify the payments as salary (triggering income tax and NI) or as director's loans. Always maintain proper records.

8. Declaring Dividends in Excess of Profits

Paying dividends when the company has insufficient accumulated profits creates illegal dividends. This is particularly common in the first year of trading when directors extract money before the first set of accounts is prepared. Always check your profit and loss position before declaring dividends.

9. Not Submitting Year-End Returns

Forgetting to tick the "final submission" indicator on your last FPS of the year, or failing to submit P60s and P11Ds on time, creates unnecessary penalties. Build year-end payroll tasks into your annual compliance calendar.

10. Confusing Company Year End with Tax Year End

Your company's accounting year end (which can be any date) is different from the PAYE tax year end (always 5 April). Payroll compliance follows the tax year, not your company's accounting period. This confusion leads to missed deadlines and incorrect filing periods, particularly for companies with year ends other than 31 March.
