HMRC record keeping requirements for sole traders and limited companies: how long to keep business records, whether bank statements are enough, and Making Tax Digital.
Zazentax Startup Series, Part 1 of 3 · Updated July 2026 · Reading time: about 8 minutes
You have registered your business. The certificate has arrived, the name is yours, and the first purchases are starting to appear: a laptop, some stock, a website subscription, a train ticket to meet a supplier. Then a small but persistent question surfaces, and if the discussion boards used by United Kingdom business owners are any guide, it surfaces for almost everyone. Do I need to keep every receipt, or are my bank statements enough?
It is one of the most frequently asked questions among people who have just registered a business and are preparing to trade. Furthermore, it is a question where a casual answer can become expensive several years later. Before proceeding to the practical system, it is worth being precise about what the law requires, because the requirement is often misunderstood in both directions: some new owners keep nothing, while others drown themselves in shoeboxes of paper they never needed to store physically.
The Short Answer
Yes, keep the receipts. A bank statement proves that money left your account. It does not prove what the money was spent on, whether the purchase was for the business, or how much of the cost is allowable against your tax. Those three facts are exactly what HMRC (His Majesty’s Revenue and Customs, the United Kingdom tax authority) will ask you to demonstrate if it ever reviews your figures. Consequently, the statement and the receipt do different jobs, and you need both.
Key point: You do not need to keep paper. HMRC accepts digital copies for almost all business records. A clear photograph of a receipt, captured at the moment of purchase and stored in an organised way, satisfies the requirement. The obligation is to keep evidence, not paperwork.
What the Law Actually Requires
Every business in the United Kingdom has a legal duty to keep records that are complete and accurate enough to support the figures in its tax returns. The rules differ slightly depending on how you trade.
If you are a sole trader or in a partnership, you must keep your business records for at least five years after the 31 January submission deadline of the relevant tax year. In practical terms, records supporting the tax year that ends on 5 April 2026 must be kept until at least 31 January 2032. That is nearly six years of retention for a receipt you might have been tempted to discard on the day you received it.
If you run a limited company, the company must keep its accounting records for six years from the end of the financial year to which they relate. Moreover, the duty sits with you personally as a director, not with the company in the abstract. Directors who fail to keep adequate records can face a penalty of up to £3,000 from HMRC and, in serious cases, disqualification from acting as a director.
Action required: Decide where your records will live before your first sale, not after your first tax return. Retrofitting twelve months of transactions from memory is the single most common self-inflicted problem described by new business owners on United Kingdom forums.
What Counts as a Record
The word “records” sounds bureaucratic, but the list is concrete. For a typical new business it means the following.
- Sales evidence: invoices you issue, till records, marketplace settlement reports if you sell through online platforms, and booking confirmations.
- Purchase evidence: receipts and supplier invoices for everything you buy for the business, from stock to software subscriptions.
- Bank and payment records: statements for the account you trade through, plus records from payment processors if customers pay you online.
- Mileage and travel logs: dates, destinations and business purpose for journeys you intend to claim.
- VAT records, but only once you are registered for VAT (Value Added Tax, the tax added to most sales of goods and services). These carry their own stricter rules, discussed below.
In addition, keep anything that explains an unusual entry: a loan agreement, a grant award letter, a note of money you personally put into the business. Future you, or your accountant, will read the bank statement and need the story behind the number.
Why Bank Statements Alone Fail
The reasoning is worth understanding, because it explains most of HMRC’s behaviour during a review. Suppose your statement shows £280 paid to a department store. That line could be office furniture, which is claimable, or a birthday present, which is not. The statement cannot distinguish between them; therefore HMRC will not accept it as proof by itself. If you cannot evidence an expense, the safe assumption during an enquiry is that the deduction is disallowed, your taxable profit rises, and interest and penalties can be added to the extra tax.
There is a second, less obvious cost. Claiming back VAT on a purchase generally requires a valid VAT invoice showing the supplier’s VAT number. A card statement is not sufficient. New businesses that register for VAT and then try to reclaim tax on earlier purchases discover this rule at the worst possible moment.
The Rules Are Becoming Digital, and the Timetable Is Short
From 6 April 2026, Making Tax Digital for Income Tax applies to sole traders and landlords whose combined gross income from those sources exceeds £50,000. Making Tax Digital, usually shortened to MTD, is the government programme that requires business records to be kept in software rather than on paper, with a summary of income and expenses sent to HMRC every three months. The threshold falls to £30,000 in April 2027 and £20,000 in April 2028, so most growing businesses will be inside the regime within a few years.
The practical consequence for a new business is encouraging rather than alarming: if you begin with a digital habit now, the rules will never require a painful change later. A receipt photographed into an app on day one is already an MTD-ready record.
A System That Takes Twenty Minutes a Week
Record keeping fails when it depends on willpower. The businesses that keep clean records design the habit so that it is nearly automatic. The following five steps are enough for most new businesses.
- Open a separate business bank account. Sole traders are not legally required to have one, but separating business money from personal money removes the single largest source of bookkeeping confusion. For a limited company it is essential, because the company’s money is legally not yours.
- Capture receipts at the moment of purchase. Photograph the receipt before you leave the shop or save the PDF (Portable Document Format file) the moment it lands in your inbox. Accounting software and free receipt apps will read the details automatically.
- Give every record a home. One app, or one cloud folder per tax year with twelve monthly subfolders, is enough at the start. The precise structure matters less than its consistency.
- Reconcile weekly. Once a week, match the week’s bank transactions to their receipts and note anything missing while the purchase is still fresh in your memory. This is the twenty minutes.
- Record the story items immediately. Money you lend the business, cash sales, and personal costs with a business element, such as use of your home, all need a short written note at the time.
What Poor Records Actually Cost: A Worked Example
Consider Leila, a sole trader who started an online homeware shop and kept only her bank statements in year one. When her accountant prepared her first Self Assessment tax return (the annual return through which sole traders report their income to HMRC), £2,300 of small cash and card purchases could not be evidenced or confidently classified: packaging bought in supermarkets, courier top-ups, market stall fees paid in cash.
Left unclaimed, that £2,300 of genuine business cost increases her taxable profit by the same amount. As a basic rate taxpayer she pays 20% income tax plus 6% Class 4 National Insurance contributions on those profits, a combined marginal rate of 26%. The avoidable extra tax is therefore £2,300 multiplied by 26%, which equals £598. That figure is larger than a year’s subscription to most bookkeeping software, and it recurs every year the habit persists.
Key point: Missing receipts do not usually cause a dramatic penalty. They cause a quiet, repeating overpayment of tax, because unproven expenses cannot be safely claimed.
Key Takeaways
- Keep evidence for every business transaction: receipts and invoices explain what bank statements cannot.
- Digital copies satisfy HMRC for almost all records; paper storage is a choice, not a duty.
- Retention periods are long: at least five years after the filing deadline for sole traders, and six years for companies.
- Making Tax Digital makes software-based records the default from April 2026 for incomes above £50,000, so starting digital is the future-proof option.
- A separate bank account plus a weekly twenty-minute reconciliation habit prevents nearly every common record keeping failure.
