Lost receipt: what to do to justify the expense?

M. Pierre, founder of ScanComptaUpdated on 21 August 20265 min read

A receipt gone missing, faded or run through the washing machine, and a business expense suddenly becomes hard to justify. Here is what the tax authority actually accepts as replacement evidence, what you lose along the way, and how to make sure the problem stops recurring.

The first thing to check: the receipt might not be lost

Before looking for a fallback, check whether the merchant can reissue the document. Most tills log every transaction and can reprint a receipt from the date, the amount and the last four digits of the card used. Supermarkets, petrol stations and equipment suppliers do this without difficulty, often from the front desk or their online customer area.

For online purchases, the invoice is almost always available in the customer account or the confirmation email. Searching your inbox by amount usually finds the document in a few seconds.

Accepted replacement evidence

If the receipt is genuinely gone for good, you need to build a consistent bundle of evidence. None of it legally replaces the receipt, but together it makes the expense defensible:

  • The bank statement or the transaction detail in your banking app: it proves the payment, the amount, the date and the payee.
  • A duplicate, a reissued invoice or a purchase order supplied by the seller.
  • A dated and signed written declaration stating the nature of the expense, the amount, the date, the place and the business reason.
  • Any contextual evidence: a booking email, a mission order, a site schedule, a client meeting entry in your diary.
Simple rule: the higher the expense, the less tolerated a reconstruction is. A reconstructed €4 toll will pass; a €1,200 equipment invoice with no document will be disallowed.

What you really lose: the VAT

The costliest issue is not the charge being disallowed, it is the VAT. Reclaiming VAT relies on a document showing the seller, the net amount, the rate and the amount of VAT. A bank statement carries none of these details, so the VAT on the lost receipt is permanently lost too.

On a budget of €400 of monthly expenses at 20%, that works out at roughly €800 of unrecovered VAT over the year if one receipt in two goes missing. This is usually the point where lost paperwork turns into a real cash-flow issue rather than an administrative hassle.

How to record it cleanly in your books

Never leave a line unexplained. Record the expense with a clear note such as "receipt lost — reconstructed", attach the bank statement and the written declaration, and flag the line to your accountant when you send the monthly batch. A transparent file, with rare and well-documented exceptions, holds up well under an audit. A silent file full of holes does not.

What the tax authority tolerates depending on the amount

There is no official threshold below which an expense without a receipt is automatically accepted. What exists is an overall judgement: a small, routine expense, consistent with your activity, backed by a bank statement and an explanatory note, almost always passes. A high, isolated or unusual expense does not.

The second criterion is frequency. Two or three reconstructions a year are accidents. Twenty "receipt lost" lines in the same year are no longer accidents: they call the bookkeeping itself into question, and that is when scrutiny tightens.

Prevention beats reconstruction: scan it the same day

Every fallback option costs time and, most of the time, VAT. The only strategy that pays off is stopping the loss before it happens: photograph the receipt before leaving the counter, while it is still readable and still in your hand.

That is the gesture ScanCompta reduces to a few seconds — photo, automatic reading of the amount, VAT and date, filing into the right folder — and it also works offline, with scans synced once the network is back.

Never lose a receipt again: the one method that actually works

Thermal paper fades, jacket pockets swallow receipts, and the shoebox never gets sorted. The only habit that survives day-to-day life is photographing the receipt the moment you receive it, before even leaving the counter, and letting the tool read the amount, VAT and date.

That is exactly what ScanCompta does: a photo, automatic data extraction, filing by client folder, and a monthly CSV export with the receipt images for your accountant. The question of the lost receipt disappears, because there is no longer a moment where the receipt has to survive the journey home.

In short

A lost receipt is not an accounting dead end: ask for a duplicate, otherwise reconstruct the expense with a bank statement and a written declaration, accept losing the corresponding VAT, and document the exception. Then remove the cause of the problem by scanning every receipt the same day.

    If I lose a €9 toll receipt, can I still claim it with just a bank statement?

    ScanComptaAuthor

    Yes — for a small amount, a bank statement plus a signed statement is usually accepted. You cannot reclaim VAT without the original receipt though.

    No. If the scan is a faithful and durable copy, the digital version is enough. We store everything for 10 years for you.

Frequently asked questions

Can you deduct an expense without a receipt?

In principle, no: the tax authority requires a supporting document to accept a charge in the accounts. In practice, a modest expense backed by a bank statement and a detailed written declaration is often tolerated, but the deduction remains challengeable in an audit, and repeating the trick draws attention.

Can you reclaim VAT without the original receipt?

No. Reclaiming VAT requires an invoice or receipt showing the amount and VAT rate as well as the seller. Without that document — or a duplicate — the VAT is permanently lost, even if the expense itself is accepted as a charge.

Does a duplicate receipt have the same value?

Yes. A duplicate issued by the merchant, a reissued invoice or a receipt reprinted from the till have the same evidential value as the original, as long as they carry the required details.

How long should you keep your receipts?

Supporting accounting documents must be kept for ten years in France. Thermal receipt ink, on the other hand, fades within a few months: photographing the receipt the same day is the only realistic way to hold that duration.
