How to organise receipts for tax time

Capture beats filing

Most receipt systems come unstuck at the same point — not the filing, but the gap between getting a receipt and doing anything with it. A receipt in a wallet or an unread inbox is easy to mislay, and thermal paper fades within months.

The fix is to shrink that gap to seconds. Photograph a paper receipt at the counter, and forward an emailed one the moment it arrives. Once capture is immediate, the filing question mostly disappears: there is no pile to sort because nothing accumulated.

It helps to notice why the gap exists at all. Filing is a decision — which folder, which month, which category — and decisions are what get postponed. Capture is not a decision, which is why it survives a busy week. Any system that asks you to classify at the moment of capture reintroduces the thing that broke the last one.

What makes a receipt worth keeping

A receipt earns its place when it can answer four questions: who you paid, how much, when, and what for. Card statements answer the first three but rarely the fourth — which is exactly the detail that decides whether something is claimable.

That is why a bank line on its own is a weaker record than a bank line with the receipt attached to it. The statement proves the money moved; the receipt explains why. Substantiation is the formal word for that pairing, and it is what separates a deduction you can hold from one you can only assert.

Where a consumption tax is involved there is a fifth requirement, and it is a legal one rather than a habit. To claim the tax back on a purchase above a small threshold, most systems require a proper tax invoice — showing the seller’s name and tax registration number, the date, a description of what was supplied, and the tax amount or a statement that it is included. An EFTPOS slip is not a tax invoice, and noticing that at the counter is far easier than noticing it in July.

A short note on the receipt is worth more than any folder structure. "Client meeting — Patel proposal" turns an ambiguous café charge into a defensible one, costs four seconds, and is the single detail most often missing when a claim is questioned. The claims worth annotating are the ones your work makes ordinary and an outsider would not — which is what the occupation deduction guides are for.

Match receipts to transactions, not to folders

Folder structures by month or category feel organised but create work: every receipt needs a decision about where it goes, and you need to remember that decision later to find it again.

Attaching each receipt to the transaction it backs removes both problems. You find a receipt the same way you find the expense — by searching the merchant or the amount — and anything unmatched stands out immediately as either a missing receipt or a transaction that needs explaining.

It also fixes the duplicate problem quietly. A receipt attached to a transaction cannot be entered twice, because the transaction is already there once; a receipt sitting in a folder can easily be claimed alongside the bank line it duplicates. That error is common, entirely honest, and awkward to explain afterwards.

A route for each of the three places receipts arrive from

Receipts arrive in three ways and each needs its own route, because a single habit will not catch all three. Paper, at a counter: photograph it before you put your wallet away. The moment of payment is the only moment you are reliably holding it, and a photo taken then is legible in a way that one taken in three weeks is not.

Email, which is now most of them: forward on arrival to a single destination rather than letting the inbox be the archive. An inbox is a terrible archive because it is also a to-do list, and receipts are the items least likely to be re-read. If your tool offers a dedicated forwarding address, a filter that forwards anything matching "receipt", "invoice" or "your order" turns the habit into a rule.

Portals, which are the ones people lose: utilities, telecoms, marketplaces and app stores that email a notification rather than a document, leaving the actual invoice behind a login. Set a recurring reminder to download those in one sitting each quarter. They are usually your largest recurring costs and almost always the last to be found.

Two smaller cases round it out. Cash purchases need the note more than any other, because there is no bank line to anchor them to. And anything bought partly for the business and partly for yourself is worth splitting on the spot — two payments where the merchant allows it, or a note recording the share, made while you still know what it was.

How long to keep them

In Australia the general rule is five years from when you prepared or obtained the record, or five years after the transaction it relates to is complete — whichever is later. Records tied to assets, such as those supporting a depreciation schedule or a capital gains calculation, can need keeping for longer, which is one reason it helps to hold them in the asset register alongside the asset rather than filed by the year they were bought.

The period differs everywhere else and is worth checking rather than assuming. The United Kingdom expects a sole trader to keep business records for at least five years after the filing deadline for the relevant tax year. Canada generally asks for six years from the end of the tax year they relate to. New Zealand generally asks for seven. The United States sets a general period of three years for most returns, extending in defined circumstances.

Every one of those authorities accepts electronic copies where the copy is a true, clear and complete reproduction that stays accessible for the period — which is a strong argument for photographing paper early, while it is still legible, rather than storing a slip that will not survive its own retention period. If you are outside the countries listed, confirm both the retention period and the rules on electronic copies before discarding any originals; both vary meaningfully. This is general information, not personal tax advice — check what applies to you with your accountant or the relevant tax authority.

The quarterly gap check

Capture handles the flow; a short periodic check handles what the flow missed. Once a quarter, list the transactions above whatever amount you consider material with no receipt attached, and work through them while the context is still recoverable. Ten minutes each quarter is enough, and it is the same ten minutes that would otherwise be forty in June with worse recall.

Work down the list rather than across it. Anything you can still identify gets a note or a re-downloaded invoice; anything you genuinely cannot gets decided rather than left — either you claim it on the strength of the bank record and the context you can reconstruct, or you do not claim it. An undecided expense is the one that stalls a return, because it comes back as a question at the worst moment.

The output of this check is also the thing your accountant most wants to receive: a set of expenses with their evidence already beside them and the gaps already named. What your accountant actually needs at tax time covers the rest of that handover, and receipts are the half that is hardest to reconstruct after the fact.
