A bank line is not a receipt

A card statement proves that money left your account and went to a named company. It does not say what you bought, whether it was for work, or how much of it was tax.

That gap is what a receipt fills, and it is why a folder of bank lines is not a set of records.

What a document usually needs to contain

Requirements differ by country, so check yours, but the same five elements appear almost everywhere. The IRS guidance on business records is a representative version: supporting documents should identify "the payee, the amount paid, proof of payment, the date incurred" and the purpose.

The supplier's name. The date. What was actually supplied. The amount, with any tax shown separately. Your name, on anything substantial.

The third one is the one bank statements never have and the one you will never remember. "Online retailer, forty pounds, March" is a mystery by December. "Microphone stand" is a cost.

Digital receipts are receipts

There is a persistent belief that a paper original is required. In most systems a legible digital copy is acceptable and has been for years; the same IRS page states that "All requirements that apply to hard copy books and records also apply to electronic records". The retention period still applies to the copy, and in the UK that is at least five years after the 31 January submission deadline for the tax year.

This matters because it makes capture nearly free. A photograph of a till receipt at the moment of purchase is a compliant record in most jurisdictions and takes four seconds. The paper version fades, and thermal paper in particular is often unreadable within a year, which is a genuinely common way a legitimate cost stops being provable.

Capture in seconds, not minutes

The system that works is the one that happens at the moment of spending.

Email receipts get forwarded to a single dedicated address or folder as they arrive, with no sorting. Physical receipts get photographed in the shop, not at home. Anything bought inside an app gets screenshotted before you leave the confirmation screen.

Sorting is a year-end job on a pile that exists. Capture is a same-minute job that cannot be done later at all, and that asymmetry is the entire design principle behind the one-minute record habit.

Costs that arrive without a receipt

Two categories cause real difficulty.

Platform fees are deducted rather than invoiced, so the evidence is a statement line rather than a document, and the statement is the record. Keep the export rather than assuming it will be available, since access to historical reports frequently ends when an account does.

Subscriptions renew silently and the receipt goes to an email address you stopped reading. Once a year, list what recurs and pull the invoices deliberately. What qualifies as a cost at all is a separate question, worked through in what counts as a cost of earning, and for anything you also use personally the answer is a proportion rather than the whole, which is the apportionment problem.

The neighbouring subjects

Documentation is dull and it is the cheapest insurance in this trade.

Records that prove what you delivered, rather than what you spent, are a different set with different retention pressure, and the buyer-facing conventions for that sit with Rate Penis. If part of what you bought is measurement equipment, whether it earns its cost is a gear question rather than an accounting one. The tooling most earners actually pay for is scoring and delivery software, and what those tools do is the clearest guide to which subscriptions are doing real work.

Fee deductions on Rate Cock appear in the earnings records attached to a judge account, described on the judges page, and exporting them yearly is worth more than remembering them.
