What Records Do I Need to Keep for HMRC?

Running a UK business means staying on top of your financial records. HMRC requires you to keep certain documents to prove your income, expenses, and taxes. Failing to keep the right records can lead to penalties or complications when it comes to filing your tax returns.

Keeping records for HMRC might sound overwhelming, but it doesn’t have to be.

At DUO Accountants, we like to keep things simple:

If it helps you track income, expenses, or taxes, you probably need to keep it.

This guide breaks down exactly what records UK business owners need to keep, making it easier to stay compliant and organised.

Why Keeping Records Matters for UK Business Owners

Keeping accurate records is not just about avoiding fines. It helps you:

• Track your business performance

• Prepare accurate tax returns

• Claim all allowable expenses

• Provide evidence if HMRC asks questions

  
  

You don’t usually send records with your return, but you must have them ready if requested. At Duo Accountants, we often advise our clients that good record-keeping saves time and stress. It also supports better financial decisions by giving a clear picture of your business's health.

What Records Do You Need to Keep?

The type of records you must keep depends on your business structure. Here’s a breakdown for sole traders, partnerships, and limited companies.

For Sole Traders and Partnerships

If you run your business as a sole trader or partnership, you need to keep:

• Sales and income records

Keep invoices, receipts, bank statements, and any other proof of money coming in.

• Business expenses

Save receipts, bills, and invoices for things like office supplies, travel, and utilities.

• VAT records (if registered)

Keep VAT invoices, VAT returns, and records of VAT paid and charged.

• Payroll records (if you have employees)

Maintain payslips, PAYE records, and pension contributions.

• Mileage logs

If you claim business mileage, keep a detailed log of journeys.

• Bank statements

Separate business and personal accounts to simplify record-keeping.

For Limited Companies

Limited companies have stricter requirements. You must keep:

• Statutory records

These include the company register, minutes of meetings, and shareholder details.

• Accounting records

All sales and purchase invoices, receipts, bank statements, and expense records.

• Payroll and PAYE records

Details of employee pay, tax deductions, and National Insurance contributions.

• VAT records (if registered)

Same as for sole traders, keep all VAT-related documents.

• Annual accounts and tax returns

Copies of filed accounts and Corporation Tax returns.

How Long Should You Keep Records?

HMRC requires UK business owners to keep records for a minimum period, depending on the business type:

• Self-Employed Individuals: Keep records for at least 5 years after the 31 January deadline.

• Limited companies: Keep records for at least 6 years from the end of the financial year they relate to.

  
  

• Personal Tax Records: Usually at least 22 months after the tax year ends.

  
  

Keeping records longer than required can be helpful if HMRC opens an investigation or if you need to check past transactions.

What Format Should Records Be Kept In?

HMRC accepts both paper and digital records. Many UK business owners now prefer digital record-keeping because it’s easier to organise and back up. Duo Accountants recommend using accounting software that can generate reports and store invoices securely.

If you keep paper records, make sure they are clear and legible. For digital records, keep backups and ensure files are accessible for the required retention period.

Examples of Records to Keep

Here are some specific examples of records UK business owners should keep:

• Invoices issued to customers: These show your income and help calculate VAT.

• Receipts for business purchases: For example, office supplies, equipment, or marketing costs.

• Bank statements: These confirm payments received and expenses paid.

• Mileage logs: Record date, purpose, start and end locations, and miles travelled.

• Payroll records: Payslips, tax codes, and pension contributions.

• Contracts and agreements: Any contracts with clients or suppliers that affect your income or expenses.

Tips for Staying Organised

Good organisation makes record-keeping easier. Here are some tips:

• Use separate bank accounts for business and personal finances.

• Keep digital copies of all receipts and invoices.

• Regularly update your records, ideally record it as you go.

• Use accounting software.

• Set reminders for tax deadlines and record retention periods.

  
  

What Happens If You Don’t Keep Proper Records?

Failing to keep the right records can lead to:

• Penalties and fines from HMRC

• Difficulty proving income or expenses during audits

• Overpaying or underpaying tax

• Increased stress and time spent sorting out issues

  
  

HMRC can impose fines starting from £100 for missing records, and penalties increase if the problem continues.
