Receipt capture for tradespeople: what HMRC actually accepts

The shoebox of thermal-printer receipts is one of the most universally-hated things about being a sole trader. The good news: HMRC has been fine with digital copies for years. The less-good news: there are rules about which digital copies count.

What HMRC actually requires

HMRC wants you to keep records of every business expense. What they care about:

• What was bought
• When it was bought
• How much was paid
• Who sold it (supplier name)
• VAT information if you’re VAT-registered (the VAT rate, amount, and supplier VAT number)

That’s it. They don’t care if the record is paper, a photo, a PDF, or typed into software. They care that it’s readable, complete, and kept for the required period.

How long you have to keep it

• Self-employed (sole trader): 5 years after the 31 January deadline of the relevant tax year. A 2025-26 expense needs to be kept until 31 January 2032.
• Limited company: 6 years from the end of the last company financial year.
• VAT-registered: 6 years for VAT records.

Thermal-printer receipts (the shiny ones from Screwfix, B&Q, Travis Perkins) fade in about 2 years. Sometimes faster in a van dashboard. If you’re relying on paper you’re betting against the physics of thermal printing.

Digital copies: the gov.uk rules

HMRC’s position (gov.uk/self-employed-records) is clear: you can throw away the paper after scanning or photographing it, as long as the digital copy is:

• Complete — you can read the whole receipt, not just part of it
• Accurate — no edits or alterations
• Accessible — you can produce it when asked

A WhatsApp photo of a receipt meets all three, as long as the photo is clear enough to read every line. Blurry photos, half-cropped receipts, or ones where the total is cut off — those don’t count.

What about the VAT information?

If you’re claiming input VAT back, the receipt (or an invoice) must show:

• The supplier’s VAT registration number
• The VAT rate for each item (or a single rate if everything’s the same)
• The total VAT amount

Most UK retail receipts over £250 are legally required to show these. Receipts under £250 can skip VAT breakdown if they’re from a VAT-registered retailer — you can still claim VAT at the retail rate, you just need the receipt as proof.

What HMRC will absolutely reject

• A bank statement on its own. "£28.50 at Screwfix" doesn’t tell them what you bought. You need the receipt.
• A handwritten note that says "bought some fittings". Not specific, not auditable.
• A photo with the amount obscured by your thumb. Re-shoot it.
• A receipt for something clearly personal bundled with business expenses. Separate them or HMRC will disallow both.

Capturing receipts without the shoebox

Three options that work:

• Phone camera + cloud folder — free, works, but you have to remember to file them monthly or it descends into chaos.
• Dedicated receipt app (Dext, Hubdoc, etc.) — good, but it’s another app and another monthly bill.
• WhatsApp photo — you’re already in WhatsApp all day. Holdfort lifts the vendor, amount, VAT, and category straight from the photo. No app, no folder, no typing.

The 30-second rule

Snap every receipt the moment you get it. Don’t put it in a pocket "to deal with later". Every receipt that goes in a pocket is a receipt that either fades, vanishes, or never gets claimed. The 30 seconds at the till is the cheapest 30 seconds you’ll ever spend.

If you’re tired of the shoebox and want voice-note-plus-photos to do the whole lot, Holdfort handles it through WhatsApp. First 7 days free.

VAT records — what changes if you’re VAT-registered

If you’re VAT-registered, your receipt-keeping rules get stricter. HMRC wants:

• Invoice-level records for every input VAT claim. Bank statement lines aren’t enough — you need the underlying invoice or receipt showing the supplier’s VAT number, the VAT rate, and the VAT amount broken out.
• Mixed-rate receipts itemised. If a single receipt has standard-rated and zero-rated items (a trip to a builders’ merchant for materials + a sandwich on the way out), the sandwich is personal and the materials are claimable. HMRC expects you to split them.
• Reverse-charge VAT on construction services. Since October 2020, VAT-registered subcontractors working for VAT-registered main contractors don’t charge VAT on their invoice — the customer (main contractor) self-charges. But you still need to record the transaction on your VAT return.

Long-term storage rules

VAT records specifically: 6 years. Other business records: minimum 5 years after the 31 January deadline of the relevant tax year. Limited companies: 6 years from the end of the company financial year.

Storage options that meet HMRC’s requirements:

• Cloud storage (Google Drive, Dropbox, OneDrive). Accessible, indexed, durable. HMRC is fine with this. Consider a folder-per-tax-year structure so a future inspector can find what they want in minutes.
• Accounting software archive. FreeAgent, Xero and Holdfort all keep historical records indefinitely while you’re a customer.
• External hard drive. Works but has the obvious failure mode — always have a second copy somewhere else. HMRC doesn’t accept "the hard drive died" as a defence.

Lost receipts — what to do

Can’t find a receipt for a real business expense? You have two options:

1. Ask the supplier for a duplicate. Most merchants keep records for 6 years. Phone them with the approximate date and amount; they can usually reissue. Screwfix, Travis Perkins, Wickes all do this routinely.
2. Claim without receipt under £10. HMRC allows small-amount expenses to be claimed without a paper receipt if you have a bank statement line and the purchase is obviously business-related. For amounts over £10 without a receipt, HMRC can disallow the claim.

One missing receipt isn’t a red flag. Consistent missing receipts indicating estimated numbers will trigger an inspection.

What triggers a VAT inspection

HMRC runs algorithmic reviews of VAT returns. Red flags:

• Returns claiming consistent net VAT refunds — you’re claiming back more than you charge, which can be legitimate for export/zero-rated trades but rings bells.
• Round-number returns — everything ending in hundreds or thousands suggests estimation, not real records.
• Dramatic quarter-on-quarter changes not explained by seasonal patterns.
• Industry anomalies — your VAT ratios vary significantly from the average for your trade code.

An inspection usually starts as a phone call asking for records. Have them ready on cloud storage, share a folder, and the inspector’s day is easy. Resist or delay and they escalate.
