For Canadian businesses, bookkeepers & accountants
It happens to everyone: the receipt fell out of a pocket, faded in the truck, or never made it to the bookkeeper. Losing it doesn't have to mean losing the deduction, but you do need to rebuild the proof. Here's what to do, in order, and what each replacement can and can't show.
A business has to keep records of all its transactions, and those records have to be backed by documents such as receipts and invoices. The CRA is direct about what happens in an audit: if your records don't support your claims, "they could be disallowed." If records are incomplete, auditors "will have to use other methods to establish your income."
For an expense, the CRA's guidance on business records says the receipt should show the date, the seller's name and address, the buyer's name and address, a full description of what was bought and, for purchases of $100 or more, the seller's GST/HST number if they're registered. A replacement should cover as much of that as you can.
When records are inadequate overall, the CRA usually asks for a written agreement to keep proper records, and can then issue a formal requirement letter. Not complying can lead to prosecution and a fine of at least $1,000.
A copy from the source is the best replacement, because it shows everything the original did. Look in this order:
If no copy exists, start with proof of payment. The CRA lists bank statements, cancelled cheques and credit card receipts among a business's records. Keep whichever applies: the card or bank statement showing the charge, the cancelled cheque, or the e-transfer confirmation.
Proof of payment shows that money left your account, when, and to whom. It doesn't show what you bought, or that the purchase was for the business. That's what the next step is for.
When a seller doesn't give a receipt, the CRA says to record the seller's name and address, the amount paid, the date and the details of the transaction in your expense journal. Doing the same for a lost receipt, kept with the proof of payment, gives you the most complete record you can have:
Write it as soon as you notice the receipt is missing, while the details are fresh.
| Replacement | Date, seller, amount | What was bought | GST/HST number |
|---|---|---|---|
| A copy from your email, online account or the supplier | ✓ | ✓ | If registered |
| Card or bank statement | ✓ | — | — |
| Cancelled cheque or e-transfer confirmation | ✓ | — | — |
| Your written note | ✓ | ✓ | — |
The strongest file has more than one: proof of payment, plus a copy or a note.
Claiming the GST/HST back as an input tax credit has its own document rules. From $100, the receipt or invoice has to show the supplier's GST/HST registration number and the tax charged, or that the total includes it. A card statement or your own note won't show either, so without a copy from the supplier, you may not be able to claim the GST/HST back on that purchase.
In Quebec, Revenu Québec also requires supporting documents for the GST and QST, and from $100 the receipt has to show the supplier's QST number as well.
A fire, a flood, a theft or a crashed computer is a different situation from one missing receipt. If your books and records were destroyed in a disaster, the CRA asks businesses to call 1-800-959-5525. For electronic records that are lost, destroyed or damaged, the CRA's guidance says to report it to your tax services office and recreate the files within a reasonable time. The same guidance says to keep proper backups at all times.
Almarix files each receipt the moment it's photographed or emailed, named and saved in the right folder of your own cloud storage, before it can fade or go missing. For bookkeeping firms, it also finds the receipts missing from statements and sends clients automatic reminders for what's still outstanding.
