Receipt Scanner (OCR)

Scan your first receipt

Use the tool above: upload a clear photo or PDF of a receipt and the receipt OCR tool returns the supplier name, transaction date, gross total and any VAT it can detect. Check each field against the paper before you save it, because no scanner is perfect on faded thermal till rolls.

How the receipt scanner app works

OCR turns the pixels of a photographed receipt into machine-readable text, then a parser looks for the patterns a UK receipt usually follows. In plain terms the workflow is: image → text → extracted fields. Here is what the parser hunts for on a typical receipt:

• Supplier — usually the largest text at the top, or the name next to a VAT number.
• Date — matched against common UK formats (DD/MM/YYYY, DD-MM-YY, or written months like "14 Jun 2026").
• Total — the figure beside words like "Total", "Amount due" or "Balance", taken as the gross (VAT-inclusive) amount.
• VAT — the line labelled "VAT", "Tax" or showing a registration number, plus the VAT amount itself.

If a receipt shows the net price and the VAT separately, the gross is simply the two added together. If it only shows a VAT-inclusive total and you know it is standard-rated, you can back out the VAT yourself: at the standard 20% VAT rate the tax is the gross divided by six. So a £30 standard-rated receipt contains £30 ÷ 6 = £5 of VAT and £25 net. Our VAT calculator does that split for you if you would rather not do the arithmetic. Remember that not everything is standard-rated — most food, books and children's clothes are zero-rated, and domestic energy is reduced-rated, so do not assume every receipt carries 20%.

Once a receipt is read, the useful next step is to categorise it: travel, stock, software, use of home, subscriptions and so on. Good categories now save hours when you fill in your Self Assessment return, because the boxes on the SA103 self-employment pages map closely to those expense types.

Worked example: a freelancer's coffee-shop receipt

Say you are a self-employed designer who met a client over lunch and bought materials on the way home. You photograph two receipts.

Receipt 1 — stationery shop, standard-rated. The till roll shows "Total £48.00" and "VAT 20%". The scanner returns supplier, date and a £48.00 gross. To record the VAT element: £48.00 ÷ 6 = £8.00 VAT, leaving £40.00 net. If you are VAT-registered on standard accounting, you reclaim that £8.00 on your next return; the £40.00 net is your allowable expense.

Receipt 2 — sandwich and coffee, £9.60. The scanner reads it fine, but the tax treatment is the catch. Everyday lunch for yourself while working locally is generally not an allowable business expense, so you would tag this as personal and leave it out of your accounts. Scanning it still helps — you have a record — but the scanner cannot decide deductibility for you.

Net result for the day: one £40 allowable expense (plus £8 reclaimable VAT if registered), and one personal item excluded. Multiply that discipline across a year of receipts and the difference to your taxable profit is real.

Why scanning beats a shoebox

HMRC expects you to keep records that back up every figure on your tax return. For the self-employed, you must keep your business records for at least five years after the 31 January submission deadline of the relevant tax year. A faded paper receipt rarely survives that long; a scanned image does. HMRC accepts digital copies of most records, so a clear scan is a valid replacement for the original in nearly all cases — see the gov.uk guidance on business records for the detail.

Scanning as you go also feeds straight into the wider digital shift. Under Making Tax Digital for Income Tax, growing numbers of sole traders and landlords will need to keep digital records and report quarterly. Capturing each receipt at the point of spending is the habit that makes those quarterly updates painless rather than a frantic catch-up. If you want to check whether the rules apply to you, the Making Tax Digital checker walks through the thresholds.

Turning scanned receipts into a tax figure

A scan on its own is just data. The value comes when those totals roll up into your accounts and then into tax. Once you have a running total of allowable expenses, you can estimate the tax those deductions save. A sole trader pays Income Tax and Class 4 National Insurance on profit (turnover minus allowable expenses), so every genuine receipt you log reduces both.

To see the effect on your own numbers, pair this scanner with a self-employed tax calculator for a full profit-to-tax estimate, or the broader Self Assessment tax calculator if you have other income too. Keep your scanned receipts flowing into an expense tracker through the year so the figure you type into the SA103 box is one you can defend.

Mileage, home and the receipts you cannot photograph

Not every deduction has a receipt. Two big ones for the self-employed are business mileage and use of home:

• Mileage. If you claim the flat HMRC mileage rate rather than actual car costs, you log journeys, not fuel receipts. Keep a trip record instead — the mileage tracker does this, and the use of home as office calculator handles the working-from-home claim.
• Direct debits and online purchases. A bank or card statement is itself a valid record. You do not always need a separate paper receipt, though a proper VAT invoice is needed to reclaim VAT.

Scan what you can, and use trackers and statements for the rest so nothing slips through.

Common mistakes when scanning receipts for tax

• Trusting the total blindly. Thermal receipts fade and OCR can misread a 3 as an 8. Glance at the gross figure against the paper before saving.
• Confusing gross and net. The scanner reads the gross (what you paid). If you are VAT-registered, record the net as the expense and the VAT separately — do not deduct the gross and reclaim the VAT, or you double-count.
• Claiming non-business spending. Everyday lunches, normal commuting and clothes you would wear anyway are usually not allowable. Scanning them is fine; claiming them is not.
• Reclaiming VAT without a VAT invoice. A card receipt that shows no VAT number is not enough to reclaim VAT on larger purchases.
• Letting receipts pile up. A year-end shoebox is how deductions get missed. Scan within a few days while you still remember what each one was for.
