What to Do When You've Lost Your Receipts
If a receipt is lost, check your bank or card statement first, since it usually shows the vendor, date, and amount, then look for a vendor duplicate or an email confirmation; most ordinary business expenses can be substantiated this way, but US travel, meals, and gift expenses fall under IRC §274(d), which requires contemporaneous records that a late reconstruction cannot fully replace.
Start with what you actually need: not the paper itself, but evidence of what was bought, from whom, when, and for how much. A lost receipt is a problem because that evidence is usually gone with it, not because the IRS or HMRC specifically require a till slip. Both accept other proof, and in most cases you can reconstruct enough of it in the next few minutes to still claim the expense properly.
What actually counts as proof, besides the receipt itself
Neither the IRS nor HMRC defines "a record" as specifically a paper receipt. The IRS's own guidance on what to keep names receipts, invoices, deposit slips, and canceled checks together, as different forms of the same thing: evidence that a transaction happened the way you say it did (IRS, What kind of records should I keep). A bank or credit card statement showing the vendor, date, and amount is a legitimate substitute for most ordinary expenses — it just can't always carry the detail a receipt would, like an itemized list of what you bought.
HMRC's position for the self-employed is similar in spirit: it expects you to keep receipts "where possible," alongside bank statements, invoices from suppliers, and other proof of business payments (GOV.UK, Business records if you're self-employed). "Where possible" is doing real work in that sentence — HMRC is not pretending every receipt survives five years of record-keeping, which is how long you're required to keep self-employed records in the UK (GOV.UK, how long to keep records).
So the real question when a receipt is gone isn't "can I still claim this?" It's "what else do I have that proves it?"
What to do in the first hour
The window where reconstruction is easy is short. A bank statement from three years ago is just as available as one from last week, but your memory of why you bought something isn't.
- Check your bank or card statement for the exact chargeVendor name, date, and amount are usually still there
- Search your email and the vendor's own account pageMany vendors keep an order history or emailed confirmation you can pull up again
- Message the vendor for a duplicateMost will reissue an invoice or receipt on request, especially for a recent purchase
- Write down the business purpose now, while you remember itThe one detail a statement never shows, and the one memory loses fastest
That last step matters more than it looks. A bank statement proves you paid a vendor; it does not prove why. "Client lunch with the Meridian account" written down today is worth far more than trying to reconstruct the same sentence from memory next April.
What usually survives a review when the receipt itself is gone
- A bank or card statement lineShows the vendor, date, and amount — the three things a record needs most
- A vendor-issued duplicate or digital order confirmationMany vendors can reissue one on request, or you already have it in an old email
- A note of the business purpose, written nowWhat it was for and which client or project it relates to
- A photo of the item or a screenshot of the listingUseful when the amount alone doesn't explain what was bought
None of these need to be perfect. A combination that tells a consistent story — a statement line plus a note plus an old email — is a stronger record than a single document of any kind, including the original receipt would have been on its own.
Where the documentation requirement gets strict
This is also where you can talk yourself into the wrong answer, because the rules are not the same for every kind of expense.
What kind of expense is it, and where are you filing?
The US split is the one people miss. Ordinary business expenses — software, supplies, a contractor's invoice — can usually be substantiated after the fact with a statement and a note. Travel, meals, gifts, and other costs under IRC §274(d) are held to a stricter standard: the IRS requires the amount, time, place, and business purpose to be documented at or near the time of the expense, specifically because these categories have a history of being exaggerated or invented after the fact (IRS Publication 463, Travel, Gift, and Car Expenses). A reasonable-sounding reconstruction of a client dinner six months later is exactly the kind of claim this rule exists to catch, and it can be denied even when you're confident the dinner happened.
HMRC's estimate allowance has a similar limit built in: an estimate is for a record that was genuinely lost, not a stand-in for one you never kept. Using "I estimate" as a habit rather than an exception is the pattern that draws scrutiny, not the occasional lost receipt it's meant to cover.
None of this is a substitute for your own accountant's judgment on a specific claim — the categories above describe what the rules are built around, not what your particular expense will survive. If you're not sure where something falls, ask before you file, not after.
What you probably can't reconstruct
A cash purchase with no card trail and no vendor record is the hardest case, because there's often nothing left to point to — no statement line, no email, sometimes no vendor who remembers the sale. If you paid cash for something you'll want to deduct, the honest options are a contemporaneous note made at the time (which is what voice capture is for) or, for recurring cash costs like tips or market stalls, a consistent log you keep going forward rather than trying to invent one retroactively. Expensorr doesn't connect to your bank or pull in transactions automatically — every record, cash or card, still has to be captured by you, which is exactly why the capture habit matters more than any reconstruction technique.
Preventing this next time
The fix isn't a better filing system for paper receipts — it's not having paper receipts to lose. Photograph a receipt the moment you get it and the record exists before it has a chance to fade in a wallet or get lost in a bag. How to track expenses from receipts covers that capture habit in full, including why reviewing scanned drafts in a weekly batch works better than trying to enter everything the day it happens.
Where to start
How to track expenses from receipts is the capture habit this whole post is arguing for. Separating business and personal money on one bank account covers labelling transactions at the moment they happen, which is the same discipline that prevents a lost-receipt scramble later. Expense categories that actually work is worth reading once your records are back in order, and expense tracking for freelancers has the fuller system all of this belongs to.
Frequently asked questions
Can I claim a business expense if I've lost the receipt?
Usually, yes, as long as you can support it with something else — a bank or credit card statement, a vendor-issued duplicate, or an email confirmation. The IRS has never required the paper receipt specifically; it requires evidence of what was bought, when, and for how much. The exception is US travel, meals, and gift expenses, which fall under IRC §274(d) and need contemporaneous records a statement alone won't satisfy.
Does a bank statement count as proof for the IRS?
For routine expenses like software, supplies, or professional services, a bank or card statement showing the vendor, date, and amount is generally accepted alongside a note of the business purpose. It's weaker on its own for travel, meals, and gifts, where the IRS requires the amount, time, place, and business purpose to be documented at the time, not reconstructed later.
Will HMRC accept an estimated expense if the receipt is gone?
HMRC allows an estimate when a record has genuinely been lost and can't reasonably be recreated, provided you can explain why you're estimating and the figure is based on something concrete, like a bank statement or a vendor's own price list. It will not accept an estimate used in place of records you simply didn't keep.
What's the fastest way to reconstruct a lost receipt?
Check your bank or card statement for the exact charge first — it's usually still there months later. If you need more detail than the statement shows, search your email for an order confirmation, check the vendor's own account or order history page, or message the vendor directly and ask for a duplicate.
How do I stop this from happening again?
Photograph every receipt the moment you get it rather than keeping the paper and meaning to enter it later. A photo taken at checkout is a record; a receipt in a jacket pocket is something you'll eventually lose or let fade past legibility.
