What Records to Keep When You're Self-Employed in the UK

If you're self-employed, HMRC expects you to keep records of all your business income and expenses. These records support the figures on your Self Assessment return — and if HMRC opens a compliance check, you'll need to show them.

This guide covers what to keep, how long to keep it, and practical ways to stay organised.

Records Checklist

Here's a quick list you can copy and keep to hand. Not every line applies to everyone — keep the records that match how your business actually works:

Sales invoices and a record of cash takings (till rolls or a takings sheet)
Receipts for goods, materials, and stock you buy
Invoices from suppliers and subcontractors
Business bank and credit card statements
Records from PayPal, Stripe, or other payment platforms
A mileage log for business journeys, if you claim vehicle costs
Home-working records (utility bills and hours worked at home) if you claim a proportion
Records of any other income (interest, grants, side income)
VAT account and VAT invoices, if you're VAT-registered
Payroll records, if you employ anyone
Year-end figures for debtors, creditors, and stock, if you use traditional accounting

The sections below explain each of these in more detail.

What Records You Need to Keep

HMRC doesn't prescribe a specific system, but you need records that show your income and expenses clearly. Here's what that includes:

Income Records

Sales invoices you've sent to clients
Till rolls or receipts for cash sales
Bank statements showing payments received
Records of any other income (interest, grants, side income)

You need to record the full amount of each sale or payment, including the date and who paid you.

Expense Records

Receipts for goods and materials you've bought
Invoices from suppliers and service providers
Bank and credit card statements showing business payments
Mileage logs if you claim vehicle expenses
Utility bills if you work from home and claim a proportion

For each expense, keep a record of the date, amount, and what it was for. A receipt alone isn't always enough — if it doesn't clearly show the business purpose, add a note. For more on which costs qualify, see what expenses you can claim.

Bank Records

Business bank statements (all of them, every month)
Personal bank statements if you use a personal account for business
Credit card statements for any cards used for business purchases
PayPal, Stripe, or other payment platform records

Additional Records (Traditional Accounting)

If you use traditional accounting rather than cash basis, you also need to keep records of:

Amounts owed to you but not yet paid (debtors)
Amounts you owe but haven't paid (creditors)
Stock value at the end of the year
Year-end bank balances
Money you've taken out of the business for personal use
Money you've put into the business from personal funds

VAT Records

If you're VAT-registered, you need separate VAT records including:

VAT charged on sales
VAT paid on purchases
VAT account summaries

PAYE Records

If you employ anyone (even occasionally), keep payroll records showing wages paid, tax and National Insurance deducted, and any statutory payments.

What Each Record Supports on Your Return

Records aren't kept for their own sake — each one backs up a specific figure on your Self Assessment return or, if you're in Making Tax Digital for Income Tax (MTD for ITSA), a specific line in your quarterly update. Knowing what each record is for makes it easier to spot the ones you can't afford to lose.

Record	Why you keep it	What it supports
Sales invoices, till rolls, takings sheets	Prove your total income	The turnover (business income) figure on the self-employment (SA103) pages, or the income total in each MTD quarterly update
Expense receipts and supplier invoices	Show costs were real and business-related	Your allowable expenses figure, or the expense categories in each MTD quarterly update
Business bank and card statements	Cross-check that income and expenses actually moved through your accounts	Both turnover and expenses if HMRC asks you to reconcile the figures
Mileage log	Record business journeys	Vehicle and travel expenses, or a simplified mileage claim
Home-working records (bills, hours)	Justify the business share of household costs	Use-of-home expenses, or a simplified flat-rate claim
VAT account and VAT invoices	Reconcile VAT charged and reclaimed	The boxes on your VAT return
Payroll records	Show wages paid and tax/NI deducted	Staff-cost expenses and your PAYE/RTI submissions
Year-end debtors, creditors, stock (traditional accounting)	Match income and costs to the right tax year	Accounting adjustments on the full self-employment (SA103F) pages

If you can tie a figure on your return back to a record like this, you're in a strong position if HMRC ever asks how you arrived at it.

How Long to Keep Records

The general rule is to keep records for at least 5 years after the 31 January submission deadline for the relevant tax year. So for the 2025/26 tax year (filing deadline 31 January 2027), you'd keep records until at least 31 January 2032. If you send your return more than 4 years late, keep records for 15 months after the date you actually submit. For the full breakdown, including edge cases, see how long to keep tax records.

Tax year	Filing deadline	Keep records until
2023/24	31 January 2025	31 January 2030
2024/25	31 January 2026	31 January 2031
2025/26	31 January 2027	31 January 2032

Digital vs Paper Records

HMRC accepts both digital and paper records for most self-employed people. Since 6 April 2026, though, Making Tax Digital for Income Tax (MTD for ITSA) requires those with qualifying income (self-employment plus property) above £50,000 to keep digital records using compatible software and send quarterly updates. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. If your qualifying income is below these thresholds, there's currently no requirement to use software — but digital records are easier to organise, search, and back up.

Paper records:

Store in labelled folders by tax year
Keep originals where possible
Protect from damage (fire, water, fading)

Digital records:

Scan or photograph receipts (phone camera is fine)
Use cloud storage for automatic backup
Organise by tax year and category (income, expenses, bank statements)
Accounting software can automate much of this

Tip: If you photograph a paper receipt, make sure the image is clear and readable. A blurry photo won't help if HMRC asks to see it. Many people photograph receipts immediately and keep the originals until the end of the tax year, then dispose of the paper copies once the digital versions are safely backed up.

What Happens If You Lose Records

If records are lost or destroyed, you need to:

Recreate what you can — request duplicate bank statements, download invoices from email, ask suppliers for copies
Estimate where necessary — use your best reasonable estimate based on available evidence
Declare it — when filing your return, note that some figures are estimates

HMRC understands that records can be lost, but you're expected to make a genuine effort to reconstruct them. Repeated failure to keep adequate records can lead to penalties.

Penalties for Inadequate Records

HMRC can charge a penalty of up to £3,000 for each failure to keep or preserve adequate records to support a tax return. In practice, HMRC has said this specific penalty is normally sought only in the more serious cases — for example, where records have been deliberately destroyed to obstruct an enquiry, or where there's a history of record-keeping failures. In many everyday situations HMRC issues a warning first, rather than going straight to the £3,000 penalty.

Good records also protect you from a second, more common problem: inaccurate figures. If your records are missing or unreliable, you're more likely to file estimated or incorrect numbers. GOV.UK notes you may have to pay interest and a penalty if your figures turn out to be wrong and you haven't paid enough tax. Gaps or round-number estimates can also make a return look less consistent, which is one of the things that can prompt HMRC to open a compliance check.

A few points worth knowing:

HMRC can charge a penalty if your records aren't accurate, complete, and readable — so legibility matters, not just having the paperwork somewhere.
Where you genuinely can't recreate a record, you can use a provisional figure (one you'll confirm later) or an estimated figure (one you won't be able to confirm), and flag it on your return.
Keeping records as you go is the simplest way to avoid both the record-keeping penalty and the risk of inaccurate figures.

Practical Tips for Staying Organised

Use a Separate Bank Account

This is the single most helpful thing you can do. A dedicated business account means every transaction is business-related by default — no need to sort through personal purchases.

Record Expenses Weekly

Don't leave it until January. Spend 15 minutes each week logging expenses and filing receipts. A small weekly habit prevents a large annual headache.

Photograph Receipts Immediately

Paper receipts fade. Take a photo the same day and save it to a dedicated folder. Some accounting apps let you snap receipts and automatically extract the details.

Back Up Everything

Keep records in at least two places. Cloud storage (Google Drive, Dropbox, iCloud) plus a local copy is a reliable approach. If your laptop breaks, your records survive.

Label Clearly

Whether paper or digital, label everything with:

Date
Amount
What it was for
Category (travel, materials, office supplies, etc.)

A receipt for "£47.50 — Screwfix — drill bits for client job — 14 March 2026" is far more useful than an unlabelled photo of a faded receipt.

What HMRC Can Ask For

During a compliance check, HMRC can request:

Your full business records (income and expenses)
Bank statements
Specific receipts or invoices
Explanation of how you calculated certain figures

You'll usually get a written request with a deadline to respond. Cooperating promptly tends to resolve checks faster.

Frequently Asked Questions

Does HMRC accept photos of receipts as valid records?

Yes. HMRC accepts digital copies including photos, scans, and screenshots — as long as they're legible and show the date, amount, and what was purchased.

How long do I need to keep my records?

At least 5 years after the 31 January filing deadline for the relevant tax year. In practice, keeping records for 6 years covers most situations. If you file more than 4 years late, keep records for 15 months after your actual submission date.

Do I need a separate business bank account?

It's not a legal requirement, but it's worth considering. A separate account makes it much easier to track business income and expenses, and reduces the chance of errors on your tax return.

What happens if I lose a receipt?

Try to recreate the record: check bank statements, email confirmations, or ask the supplier for a duplicate. If you can't recover it, use a reasonable estimate based on available evidence. HMRC expects a genuine effort to maintain records.

Can HMRC fine you for poor record-keeping?

Yes. HMRC can charge a penalty of up to £3,000 for each failure to keep or preserve adequate records for a tax return, though it's normally reserved for serious cases such as deliberate destruction of records or a history of failures. More commonly, weak records lead to inaccurate figures, which can result in interest and penalties if you've underpaid tax.
