Benefits in Kind — Mandatory Payrolling from April 2026

The End of the P11D (For Most Benefits)

If you provide benefits to yourself or your employees through your limited company — company cars, private medical insurance, gym memberships — you have almost certainly been reporting them on the P11D form each year after the tax year ends. That process is about to change fundamentally.

From 6 April 2026, HMRC is making payrolling of benefits in kind (BiKs) mandatory for most benefit types. This means the tax owed on those benefits will be collected in real time through your monthly payroll, rather than being settled retrospectively through your tax code the following year.

The shift has been coming for years. Voluntary payrolling has been available since 2016, and HMRC has been encouraging employers to adopt it. Now the voluntary phase is ending and the mandate is arriving.

What Is Changing

April 2026: Mandatory for Most Benefits

From 6 April 2026, employers must payroll the following common benefits in kind:

• Company cars and car fuel benefit
• Private medical insurance
• Beneficial loan interest (loans above £10,000)
• Gym memberships and subscriptions
• Assets placed at the employee's disposal
• Credit cards used for personal expenses
• Vouchers and credit tokens
• Living accommodation (in most cases)

This covers the vast majority of benefits that directors of small limited companies typically provide.

April 2027: Full Mandate

By April 2027, the mandate extends to cover essentially all remaining benefit categories, completing the transition away from the P11D process. A small number of exemptions will remain (notably employer-provided accommodation in certain circumstances), but for practical purposes, the P11D era is ending.

What Stays Exempt

Some benefits remain outside the BiK regime entirely and do not need to be payrolled:

• Pension contributions by the employer
• Trivial benefits under £50 per occasion (up to £300/year for directors)
• Mobile phones (one per employee, for business use)
• Cycle to work schemes under salary sacrifice
• Workplace parking

These exemptions are unchanged by the new payrolling rules.

How Payrolling Works vs the P11D Process

The Old Way (P11D)

Under the traditional approach, the cycle works like this:

1. You provide a benefit during the tax year (e.g., private medical insurance costing £1,200/year)
2. After the tax year ends, you report the benefit on a P11D form (due by 6 July)
3. HMRC adjusts the employee's tax code for the following year to collect the tax owed
4. The employee pays the tax through reduced take-home pay the next year

This creates a lag of up to 18 months between receiving the benefit and paying the tax.

The New Way (Payrolling)

Under mandatory payrolling:

1. You provide the same £1,200/year benefit
2. Each month, you add £100 to the employee's taxable pay in the payroll
3. PAYE is deducted on the benefit amount in that month's payslip
4. The employee pays the tax in real time — no surprises, no catch-up

For a higher-rate taxpayer, a £1,200 benefit costs £40/month in additional tax (£1,200 x 40% / 12). That comes straight off the monthly pay packet rather than arriving as a reduced tax code months later.

What About Class 1A National Insurance?

Employers still owe Class 1A NI on benefits in kind at 15% (following the employer NI increase). This does not change with payrolling — it is still reported and paid annually. The difference is that Class 1A NI will be reported through the Full Payment Submission (FPS) rather than a separate P11D(b) form.

Who Is Affected

Company Directors Providing Benefits to Themselves

If you are a director of a small limited company and you receive any of the following through the company, you are affected:

• Private medical insurance — one of the most common director benefits
• A company car — the car benefit and fuel benefit must both be payrolled
• Beneficial loans — if the company has lent you more than £10,000
• Subscriptions — professional subscriptions not directly required for the role

Even if you are the sole director with no other employees, you must payroll these benefits from April 2026.

Employers With Staff Benefits

If your company provides benefits to other employees, you must set up payrolling for all affected benefit types across your entire workforce. You cannot payroll for some employees and P11D for others within the same benefit category.

Worked Example: Director With Medical Insurance and Company Car

Sarah is a sole director of a consultancy. Her company provides:

• Private medical insurance worth £1,800/year
• A company car with a benefit-in-kind value of £7,200/year (list price £30,000, 24% BiK percentage)

Monthly payroll additions from April 2026:

Sarah is a 40% taxpayer, so her monthly PAYE bill increases by £300 (£750 x 40%). Her company also owes 15% Class 1A NI on the £9,000, which is £1,350 per year.

Previously, Sarah would have seen no change to her monthly pay — the tax would have been collected through a reduced tax code the following year. Now, it comes out each month in real time.

What Directors Need to Do Before April 2026

1. Review Your Current Benefits

List every benefit your company provides. Check whether each one falls under the mandatory payrolling requirement. If you have not been filing P11Ds at all, this is a good time to get compliant — HMRC has historical records and the transition will surface any gaps.

2. Update Your Payroll Software

Your payroll system needs to support benefit-in-kind payrolling. Most modern cloud payroll software already does, but you need to:

• Register the specific benefits being payrolled
• Enter the correct cash equivalent or taxable value for each benefit
• Ensure the monthly additions are reflected in the FPS sent to HMRC

3. Calculate the Cash Flow Impact

Your employees (including you as a director) will see lower monthly take-home pay. This is not additional tax — it is the same tax paid earlier. But the cash flow impact is real and you should plan for it.

4. Communicate With Your Team

If you have employees receiving benefits, tell them their net pay will decrease from April 2026 — not because their pay has been cut, but because BiK tax is now collected monthly. Failing to explain this will cause confusion and complaints.

5. Consider Your Benefit Strategy

With the tax impact now visible every month, some directors reconsider whether certain benefits are worth providing through the company. A benefit with a high BiK value but low personal value may not be worth the monthly tax hit.

Key Dates

What This Means for Your Tax Strategy

The substance of the tax has not changed — you owe the same amount whether it is collected through a P11D or through payroll. But the visibility has changed. Directors who were unaware of how much tax their benefits cost will now see it every month on the payslip.

This is a good time to review your overall salary and dividend strategy alongside your benefit package. With income tax thresholds frozen until 2031 and dividend tax rising, the full picture of how you extract value from your company matters more than ever.

Frequently Asked Questions

Do I still need to file a P11D if I payroll benefits?

No — for benefits that are payrolled, you do not submit a P11D. However, you still need to report Class 1A NI, which will be included in your Full Payment Submission. If you provide any benefits that are temporarily exempt from mandatory payrolling, those would still require a P11D until April 2027.

What happens if I do not set up payrolling by April 2026?

HMRC has not yet confirmed specific penalties for non-compliance, but failing to operate payrolling when required will be treated similarly to other PAYE failures. You risk penalties for incorrect FPS submissions and potential interest charges on underpaid tax. Getting it right from the start avoids complications.

Can I stop providing benefits through my company instead?

Yes. If the monthly tax visibility makes a benefit look unattractive, you can stop providing it and take additional salary or dividends instead. Run the numbers first — some benefits like pension contributions and trivial benefits remain tax-efficient regardless of the payrolling change.

Does this affect salary sacrifice arrangements?

Salary sacrifice arrangements are separate from benefit-in-kind payrolling. Where a valid salary sacrifice is in place (e.g., for pension contributions or cycle to work), the employee gives up salary in exchange for the benefit — there is no BiK to payroll. However, some benefits provided through salary sacrifice do create a BiK (notably company cars), and those must be payrolled under the new rules.
