Short answer
To scan receipts for taxes, capture each receipt the day you get it, make sure the whole receipt is legible (supplier, date, items, total and tax), check the extracted total, assign a category, and back up the images and a CSV regularly. Most tax authorities accept complete, legible digital copies, but retention periods and rules differ by country.
Key takeaways
- Capture on the day: paper fades and goes missing; a fresh receipt can still be reprinted.
- A usable scan shows the supplier, date, what was bought, total and tax — the details tax authorities expect.[1][2]
- Check the total and tax at capture; NexaLink Scanner flags uncertain values and won't save a low-confidence total until you confirm it.
- Keep backups outside the phone for the whole retention period — 3 to 6 years or more depending on country.
What makes a scanned receipt usable as tax evidence
Tax authorities do not ask for photographs; they ask for records. The IRS, for example, says supporting documents should show the payee, the amount paid, proof of payment, the date and a description of what was bought.[1] HMRC says a complete scan of a VAT invoice means you don't need the paper original.[2] The ATO accepts digital copies that are true and clear reproductions.[3] The common thread is completeness and legibility.
| Check | Why |
|---|---|
| Whole receipt in frame, edges visible | A cropped total or missing VAT number can invalidate the record |
| Supplier name and tax number readable | Needed to reclaim VAT/GST in most countries |
| Date readable | Places the expense in the right period |
| Line items readable | Shows the purchase was for the business |
| Total and tax readable | The numbers you claim |
| Long receipts captured end to end | Fuel and supermarket receipts often run long |
- Receipt scanning (for tax)
- Capturing a complete, legible digital copy of a receipt and recording its supplier, date, total and tax, so the expense can be claimed and the copy produced if a tax authority asks.
Step by step with NexaLink Scanner
- Capture. Open NexaLink Scanner and point the camera at the receipt. Edges are found automatically. Use long-receipt mode for till rolls and batch mode for a pile. It works offline.
- Check. Merchant, date, total and tax are read on the phone. Anything the app is unsure about is flagged — and a low-confidence total cannot be saved until you confirm it.
- Categorise. Choose one of five default categories on Free, or your own categories, projects and tags on Pro. Match them to your tax form — see self-employed expense categories.
- Note the purpose for meals, travel and anything unusual. A one-line note now saves an awkward question later.
- Export. Each month or quarter, export CSV (free on every plan). On Pro, also save the PDF expense report.
- Back up. Keep the exports with your tax records outside the phone.
Common mistakes
- Scanning in a batch at year end. Thermal receipts can fade, and by then you can't ask for a copy.
- Keeping only the card slip. It proves payment, not what you bought or the tax charged.
- Trusting an auto-read total blindly. Tip lines, "amount tendered" and loyalty discounts confuse readers. Confirm it.
- One huge "miscellaneous" category. Your accountant will have to recategorise everything.
- Only one copy. If the phone is lost, so are the records. Export.
- Throwing paper away too early in a country with stricter imaging rules — see going paperless.
What changes by country
Thresholds and retention periods vary. In the UK, VAT records are generally kept for 6 years.[2] In the US, generally 3 years from filing.[4] In Australia, 5 years.[3] See how long to keep receipts for a comparison, and the country guides for what a valid receipt must show where you are.

Frequently asked questions
Are scanned receipts valid for taxes?
In most countries, yes, if the copy is complete and legible. HMRC, the ATO and the IRS all accept digital records that meet their rules.[2][3][1] Some countries, such as Canada, have formal imaging requirements before you discard paper.
What is the best way to scan receipts for taxes?
Capture each receipt on the day with a phone app that checks the total and tax, categorise it straight away, and export a CSV and images regularly to a backup.
Do I need to keep the paper after scanning?
Often not, if the scan is complete — but check your country's rule. See our guide to going paperless with receipts.
Can I scan receipts with my phone camera?
Yes. A receipt app adds edge detection, reading of the total and tax, categories and export, which a camera roll does not.
What should I do with faded receipts?
Capture what is legible now, ask the supplier for a copy if possible, and keep supporting evidence such as the card statement entry.
Does NexaLink Scanner work offline?
Yes. Capture and reading happen on the phone, so it works without a connection.
Is NexaLink Scanner free?
Free covers 50 receipts with on-device reading, search, five categories and CSV export. Pro is $4.99 a month or $39.99 a year.
