How Long Should You Keep Tax Records in the UK?
Keeping financial records is not the most exciting part of managing your finances, but it can become very important if HMRC asks questions later.
Many people are unsure how long they should keep:
- Tax returns
- Bank statements
- Payslips
- Receipts
- Property records
- Business invoices
- Investment statements
Some records may only need to be kept for a few years.
Others can be worth retaining for much longer, particularly where they relate to property, investments or significant transactions.
The correct retention period depends on what the records relate to and which tax rules apply.
Why keeping records matters
Good records can help you:
- Complete tax returns accurately
- Support expense claims
- Calculate capital gains
- Respond to HMRC enquiries
- Prove when an asset was purchased
- Confirm how much was originally paid
- Support business accounts
- Resolve disputes
Without supporting documentation, it can be much harder to demonstrate that a tax calculation or expense claim is correct.
How long should Self Assessment records be kept?
If you complete a Self Assessment tax return, HMRC requires records to be retained for a minimum period.
The exact period depends on the type of income involved.
For example, self-employed individuals generally need to keep business records for longer than someone completing Self Assessment solely because of other personal income.
The safest approach is to understand which retention rule applies to your circumstances rather than deleting records immediately after the return has been submitted.
What records should you keep for Self Assessment?
Useful records may include:
- P60s
- P45s
- P11Ds
- Bank interest statements
- Dividend vouchers
- Pension information
- Rental-income records
- Expense receipts
- Gift Aid records
- Investment statements
- Foreign-income details
If HMRC opens an enquiry, these documents may help explain how figures on the return were calculated.
What about business records?
Businesses should retain records supporting their accounting and tax submissions.
These may include:
- Sales invoices
- Purchase invoices
- Receipts
- Bank statements
- Credit-card statements
- Payroll records
- VAT records
- Loan agreements
- Asset purchases
- Expense claims
- Accounting reports
Good bookkeeping makes record retention much easier because documents can increasingly be stored digitally alongside the relevant transactions.
Limited companies have their own record-keeping responsibilities
Limited companies need to maintain adequate accounting records.
These records support:
- Annual accounts
- Corporation Tax returns
- VAT Returns
- Payroll
- Companies House filings
Company directors remain responsible for ensuring appropriate records are retained, even where bookkeeping and accounting work is outsourced.
The company should be able to explain:
- Money received and spent
- Assets owned
- Debts owed
- Stock where relevant
- Transactions supporting the accounts
Keep property records for longer
Property records can be particularly important because a property may be owned for decades.
Documents worth retaining can include:
- Original purchase completion statement
- Legal fees
- Stamp Duty Land Tax records
- Improvement invoices
- Professional fees
- Sale documents
- Estate-agent fees
These records may eventually be needed when calculating Capital Gains Tax.
If you sell a property twenty years after buying it, finding the original paperwork at that point can be extremely difficult.
For significant assets, long-term record retention is often sensible even where the normal minimum tax-record period has passed.
Keep investment purchase records
The same principle applies to investments.
If you buy:
- Shares
- Funds
- Cryptoassets
- Other investments
you may eventually need to establish the original acquisition cost when the asset is sold.
Keep records showing:
- Purchase date
- Number of units
- Purchase price
- Transaction fees
- Later purchases
- Sales
- Corporate actions where relevant
Without this information, calculating the correct gain can become much more complicated.
What about cryptocurrency records?
Cryptoassets can create particularly difficult record-keeping problems.
A taxpayer may make hundreds of transactions involving:
- Purchases
- Sales
- Exchanges
- Transfers
- Staking rewards
- Other income
Do not assume the exchange or platform will retain all the information indefinitely.
Keeping your own transaction history can be valuable if the platform later closes or changes its reporting system.
Should you keep paper receipts?
Not necessarily.
Digital record keeping is increasingly common.
A clear digital copy of an invoice or receipt may be much easier to store and retrieve than paper.
You could:
- Photograph receipts
- Download PDF invoices
- Store documents in accounting software
- Organise files by tax year
- Maintain secure cloud backups
The key requirement is that records remain legible, complete and accessible if they are needed later.
Do not rely entirely on your bank statements
A bank statement may prove that you paid £600 to a supplier.
It may not prove what you actually bought.
This can matter when determining whether an expense is:
- Business-related
- Capital or revenue
- VAT-inclusive
- Personally incurred
Keep invoices and receipts alongside payment records where appropriate.
VAT records require particular care
VAT-registered businesses need records supporting the VAT charged to customers and VAT reclaimed on purchases.
These may include:
- VAT invoices
- Sales records
- Purchase records
- Credit notes
- Import documentation
- VAT account information
Incomplete VAT records can make it difficult to support a reclaim during an HMRC review.
If you need support with VAT compliance, Merranti provides VAT guidance and accountancy services.
Payroll records should also be retained
Employers should keep records supporting payroll calculations.
These can include:
- Employee details
- Salary records
- PAYE calculations
- National Insurance
- Pension contributions
- Benefits
- Expenses
- Statutory payments
Good payroll records help support both tax compliance and employment administration.
What happens if HMRC opens an enquiry?
HMRC can ask for records supporting the information reported on a tax return.
The enquiry may involve:
- Income
- Expenses
- Property
- Dividends
- Capital gains
- Business transactions
If accurate records are readily available, responding is usually much simpler.
Poor or missing records can make the process longer and potentially more expensive.
What if records are lost?
Documents can disappear because of:
- Computer failure
- Lost paperwork
- Flood or fire
- Business closure
- Supplier systems changing
Where possible, maintain backups.
For important documents, consider having:
- Cloud copies
- Local backups
- Accounting-software records
- Original documents where necessary
If something is lost, try to obtain replacement copies from:
- Banks
- Suppliers
- Solicitors
- Employers
- Investment platforms
- Accountants
Do not simply estimate figures without explaining the position.
Should you keep records after the minimum period?
Sometimes, yes.
The statutory minimum tells you how long records must generally be retained.
It does not necessarily tell you when they stop being useful.
Consider keeping documents longer where they relate to:
- Property
- Significant investments
- Company shares
- Large loans
- Business acquisitions
- Pension transactions
- Major asset purchases
A document that appears irrelevant today may become important years later.
A simple digital filing system
You do not need a complicated document-management platform.
A simple structure might include:
2026/27 Tax Year
- Employment
- Savings
- Dividends
- Property
- Investments
- Pensions
- Gift Aid
- Tax Return
For a business:
2026 Financial Year
- Sales
- Purchases
- Bank
- VAT
- Payroll
- Assets
- Loans
- Tax
- Accounts
Consistency matters more than complexity.
Frequently Asked Questions
How long should I keep tax records?
The minimum period depends on the type of tax return and your circumstances. Self-employed taxpayers and limited companies have specific record-retention requirements.
Can I keep tax records digitally?
Yes, digital record keeping is widely used provided the documents remain accurate, legible and accessible.
Should I throw away old property paperwork?
Be cautious. Original property purchase and improvement records may be needed many years later when calculating Capital Gains Tax.
Does my accountant keep everything for me?
Your accountant may retain certain records, but you should not assume they are responsible for permanently storing every document connected to your finances.
Do I need receipts if transactions appear on my bank statement?
Bank statements are useful evidence, but invoices and receipts often contain additional information needed to support the tax treatment.

Keep clear records for:
- Income
