Record Keeping Requirements for UK Limited Companies: The Complete Guide

Record keeping isn't the most exciting part of running a limited company, but it's one of the most important. Get it wrong, and you could face penalties of up to £3,000 from HMRC, plus serious problems if you're ever investigated. This guide covers everything UK limited company directors need to know about keeping compliant records.

Why Record Keeping Matters

Limited companies have a legal obligation to maintain accurate financial records. This isn't optional guidance. The Companies Act 2006 requires every company to keep accounting records that are sufficient to show and explain the company's transactions, disclose with reasonable accuracy the company's financial position at any time, and enable directors to prepare accounts that comply with the Act.

HMRC has parallel requirements under tax law. Your records must allow you to complete accurate tax returns and support any figures you report. If HMRC opens an enquiry and you can't produce adequate records, you're immediately on the back foot.

Beyond legal compliance, good record keeping makes your life easier. You'll spend less time hunting for documents at year-end, your accountant can work more efficiently (saving you money), and you'll have the information you need to make sound business decisions.

What Records You Must Keep

The law requires you to keep a comprehensive set of financial records. Here's what that means in practice:

Sales and income records:

All invoices you issue to customers
Credit notes issued
Records of cash sales
Bank statements showing income received
Contracts and agreements with customers

Purchase and expense records:

Invoices and receipts from suppliers
Proof of payment for all business expenses
Contracts with suppliers
Credit notes received
Petty cash records

Banking records:

Bank statements for all business accounts
Cheque book stubs
Paying-in slips
Bank reconciliations
Details of bank charges and interest

Asset records:

Purchase invoices for equipment, vehicles, and other assets
Details of disposals and sales
Depreciation schedules
Hire purchase or lease agreements
Insurance documentation

Employment records (if you have employees):

Payroll records and calculations
PAYE deduction records
National Insurance contributions
Employee contracts and P45/P60 documents
Benefits in kind documentation
Statutory sick pay, maternity pay, and similar records

VAT records (if VAT registered):

VAT invoices received and issued
VAT account showing calculations
Import and export documentation
Records of any VAT adjustments
Bad debt relief claims

Corporate records:

Minutes of board meetings
Shareholder resolutions
Share registers and transfers
Director appointment documentation
Registered office correspondence

How Long to Keep Records

Different records have different retention requirements. Here's what you need to know:

Standard 6-year retention:

Most accounting records must be kept for at least 6 years from the end of the accounting period they relate to. This includes:

Invoices and receipts
Bank statements
General ledgers and journals
VAT records
PAYE records
Annual accounts and tax returns

The 6-year rule aligns with HMRC's enquiry window. For Corporation Tax, HMRC can open an enquiry into your return up to 12 months after filing, but they have 6 years to assess underpaid tax if they believe there are errors.

10-year retention:

Some records should be kept longer:

Records relating to land and property transactions (keep for 10 years after disposal)
Capital asset purchases (keep for 6 years after you dispose of the asset)
Directors' loan account records (keep for the full loan period plus 6 years)

Indefinite retention:

Certain corporate documents should be kept permanently:

Certificate of incorporation
Memorandum and Articles of Association
Share certificates and stock transfer forms
Minutes of general meetings and board meetings
Annual returns and confirmation statements filed

Fraud or deliberate error:

If HMRC believes there has been fraud or deliberate error, they can go back 20 years. While you're not required to keep records this long, any records you do have from earlier periods could become relevant.

Digital vs Paper Records

The good news is that HMRC accepts digital records on exactly the same basis as paper records, provided certain conditions are met.

Requirements for digital records:

Your digital records must be:

Complete and accurate
Readable and accessible
Backed up appropriately
Capable of being converted to paper if required

You can scan paper receipts and invoices, then destroy the originals, as long as the digital copies are clear and legible. HMRC explicitly allows this approach.

Advantages of digital record keeping:

Searchability: Find any document in seconds instead of rifling through boxes
Space saving: No need for filing cabinets full of paperwork
Disaster protection: Properly backed up digital records survive fire, flood, and theft
Sharing: Easily send documents to accountants, auditors, or HMRC
Making Tax Digital compliance: Digital records are required for MTD anyway

Best practices for digital records:

Use a consistent naming convention for files (e.g., YYYY-MM-DD_Supplier_Description)
Organise documents into logical folders by year and category
Scan documents at sufficient resolution to be readable (300 DPI minimum)
Store records in widely-used formats (PDF, CSV) that will remain accessible
Maintain at least two backup copies in different locations

HMRC-Compliant Record Keeping

HMRC sets out specific requirements for what constitutes adequate records. Meeting these standards protects you if you're ever investigated.

Transaction records must show:

The date of each transaction
The amount of each transaction
What the transaction was for
The name of the supplier or customer
How payment was made

VAT records must additionally show:

The VAT charged or paid
The VAT rate applied
The supplier's or customer's VAT number (where applicable)
Your VAT calculations for each return period

Penalties for inadequate records:

HMRC can impose penalties of up to £3,000 if your records are inadequate. In practice, penalties typically apply when:

Records are so poor that HMRC cannot verify your tax returns
Records have been deliberately destroyed
False or misleading records have been created
Records are incomplete or missing for significant periods

Beyond penalties, inadequate records make it much harder to defend yourself during an HMRC enquiry. If you can't demonstrate that your tax return is accurate, HMRC may estimate your tax liability, and their estimates tend not to be generous.

Cloud Storage and Backup Strategies

Cloud storage has become the standard for business record keeping. It offers automatic backup, accessibility from anywhere, and protection against local disasters.

Recommended approach:

Use accounting software with built-in document storage (like AccountsOS)
Maintain a secondary backup with a different cloud provider
Keep critical documents (incorporation papers, share certificates) in physical form as well
Test your backup and restore process periodically

Security considerations:

When storing financial records in the cloud, ensure:

Strong, unique passwords for all accounts
Two-factor authentication enabled
Encryption in transit and at rest
Reputable providers with appropriate security certifications
Access controls limiting who can view sensitive documents

Choosing a cloud provider:

Select providers based in jurisdictions with strong data protection laws. UK and EU providers must comply with GDPR, giving you assurance about how your data is handled. Check that your provider offers:

Regular automated backups
Version history for documents
Audit trails showing who accessed what
Ability to export all data if you switch providers

What Happens If You Lose Records

Losing records creates serious problems, but there are steps you can take to mitigate the damage.

Immediate actions:

Document what happened (fire, theft, flood, hardware failure, etc.)
Report any theft to the police and obtain a crime reference number
Notify HMRC and Companies House if filing deadlines will be affected
Contact your bank for duplicate statements
Reach out to major suppliers and customers for copies of invoices

Reconstructing records:

Work with your accountant to reconstruct as much as possible:

Bank statements can usually be obtained from your bank (they must keep records for 7 years)
Credit card statements are similarly available
Major suppliers may have copies of invoices they sent you
Your own sales invoices may be recoverable from customers
HMRC can provide copies of returns previously filed

HMRC's approach:

If you genuinely lost records through circumstances beyond your control, HMRC typically takes a pragmatic approach. They're interested in collecting the right amount of tax, not punishing people for genuine misfortune. However, you must:

Report the loss promptly
Take reasonable steps to reconstruct records
Document your reconstruction efforts
Be transparent about any gaps that remain

If HMRC believes records were deliberately destroyed or that you're using "lost records" as an excuse, their response will be very different. Deliberate record destruction is a criminal offence.

Making Tax Digital Record Keeping Requirements

Making Tax Digital (MTD) adds specific digital record keeping requirements that go beyond standard rules.

Current MTD requirements:

VAT-registered businesses must:

Keep records digitally using MTD-compatible software
Maintain digital links between software packages (no manual retyping)
Submit VAT returns directly from their software

MTD for Income Tax (from April 2026):

Self-employed individuals and landlords with income over £50,000 must:

Keep digital records of income and expenses
Submit quarterly updates to HMRC
File an end of period statement
Submit a final declaration

While MTD for Income Tax doesn't directly apply to limited companies, many directors have personal self-employment or rental income that will be affected.

MTD for Corporation Tax (expected 2027-2028):

HMRC plans to extend MTD to Corporation Tax. When this happens, limited companies will need to:

Maintain digital accounting records
Use MTD-compatible software
Submit returns digitally with digital record links

Preparing now by adopting proper digital record keeping will make the transition straightforward.

What counts as a digital link?

A digital link is a transfer or exchange of data electronically between software programs or products. Manual copying and pasting, or retyping data, does not count. Acceptable methods include:

Automatic data transfer between systems
CSV file exports and imports
API integrations between software
XML data transfers

Frequently Asked Questions

Can I throw away paper receipts after scanning them?

Yes, HMRC accepts digital copies of documents, so you can destroy paper originals once you have clear, legible digital versions. Ensure your scans are high quality (readable when enlarged) and properly backed up before disposing of originals.

What if a supplier doesn't provide a VAT invoice?

If you're VAT registered and need to reclaim VAT, you must obtain a valid VAT invoice. Without one, you cannot reclaim the VAT. Contact the supplier and request a proper VAT invoice showing their VAT number, the VAT amount, and other required details.

How should I record cash transactions?

Cash transactions require the same documentation as other payments. Keep receipts for cash purchases, record all cash sales in a cash book, and count and reconcile your petty cash regularly. For businesses with significant cash transactions, daily records are essential.

Do I need to keep records if my company is dormant?

Even dormant companies must maintain basic records, including records of dormant account filings, any fees paid (filing fees, registered office charges), and corporate documents like the memorandum and articles. If your company becomes active again, you'll need these records.

What records do I need for mileage claims?

To claim mileage, keep a log showing the date of each journey, start and end points, business purpose, and miles travelled. You can use a paper log book or a mileage tracking app. Without contemporaneous records, HMRC may challenge mileage claims.

How do I handle records for mixed personal and business expenses?

If an expense has both personal and business elements (like a phone used for both), keep the full receipt and document how you've calculated the business proportion. Common methods include percentage based on usage or itemised allocation of specific costs.

What should I do if I'm selected for an HMRC enquiry?

Gather all requested records promptly and completely. Cooperate with HMRC's reasonable requests, but seek professional advice before responding to complex questions. Good record keeping makes enquiries far less stressful as you can demonstrate that your returns are accurate.

Are screenshots of online transactions acceptable?

Screenshots can serve as supporting evidence but are not ideal. Where possible, download proper invoices or statements in PDF format. Screenshots should include the date, amount, description, and clearly identify the transaction. Ensure they're saved in a durable format.

How long should I keep employee records after they leave?

Keep employee records for at least 3 years after the end of the tax year they relate to. However, some records (P45s, pension auto-enrolment records) should be kept for 6 years. When in doubt, keep records longer rather than disposing of them prematurely.

Can I use personal cloud storage like Google Drive for business records?

You can, but dedicated accounting software with document storage is preferable. If using general cloud storage, ensure you have proper backups, security measures, and a consistent filing system. The records must be accessible and organised enough for HMRC to review if needed.
