How to organize receipts — filed as they arrive, not every April

Nobody files receipts in March. The work is always done in a single miserable session, months later, from an inbox that has moved on.

How do you organize receipts?

Keep one folder per tax year, split it by what you will do with the receipt — business expenses, travel, personal — and name each file by merchant and date. Photograph paper receipts the day you get them; for emailed ones, file them the week they arrive. The system only works if filing happens then, not in March.

  1. File them the week they arrive, not in March

    A receipt is easiest to identify the day it lands, while you still remember the trip or the purchase. Months later you are reconstructing context from a filename someone else chose.

  2. Let the merchant and date come from the receipt

    Names are rebuilt from the document's contents, so the folder sorts by merchant and date on its own. That is what makes a year's receipts reviewable instead of just present.

  3. Watch the 3 KB floor on tiny images

    Attachments under 3 KB are skipped before classification, which throws away signature graphics and tracking pixels. A genuinely tiny receipt image can be dropped too — if one never appears in History, check its size first.

Why this category rots quietly

Receipts do not feel urgent when they arrive. Each one is a small confirmation of something already paid, so it stays in the inbox, and the pile grows quietly for eleven months without ever demanding attention.

They are also the messiest category technically. A receipt mail often carries three or four attachments where only one is the receipt — the rest are logos, signature images and social icons — and the receipt itself may be a 40 KB image rather than a tidy PDF.

What the April session actually costs

The annual catch-up is the most expensive way to do this, and not because of the hours. It is done under deadline, from memory, against an inbox where search terms have stopped being obvious — and the receipts that cannot be found within a few minutes simply stop being claimed.

That is the real number: not the afternoon, but the deductions quietly abandoned because reconstructing the paperwork cost more than the deduction was worth.

Sorting by what you will do with it in April

Receipts are worth splitting by their eventual use rather than by vendor, because in April the question is never “who sold me this” — it is “can I claim it”.

Too vague

“Receipts”

Every business on earth calls its confirmation email a receipt, so this collects parking, software renewals and client dinners into one undifferentiated folder.

Works

“Receipts for travel and client meals that I will claim as expenses. Not personal shopping, not subscription renewals.”

Splits by what you will do with the document at tax time, which is the only distinction that matters when the folder is finally opened.

What a filed receipt looks like

Vendor and date are read off the receipt, whether it arrived as a PDF or as a photo:

Receipt_Renfe_2026-05-19.pdf

It goes to Expenses Travel 2026. Twelve months of that produces a folder sorted by date without anyone having sorted anything, which is the state you want it in when the deadline arrives.

Worth knowing first

Attachments under 3 KB are skipped before anything is classified. That threshold exists to throw away signature graphics and tracking pixels, and it works — but it also means a genuinely tiny receipt image can be discarded silently. If a receipt you expected never shows up in History, its size is the first thing to check.

Questions about receipts and expenses

Will it catch receipts already sitting in my inbox?

Yes, for a mailbox connected with an app password: “Archive past mail” in Connections goes back 30 days on Free and up to 12 months on Pro and Business, and files only the receipts your rules match. It checks about 40 emails every 10 minutes, so a year can take hours. Outlook connected with Microsoft sign-in files new mail only. Connecting in January rather than April is still most of the value.

What about receipts that are just HTML in the message body?

Those cannot be filed — there is no attachment. Many services have a setting to attach a PDF copy instead, and switching it on is worth the two minutes per vendor.

Can I keep personal and business receipts apart?

Yes, by pointing a rule at one specific mailbox. A rule restricted to your work address will not see anything that arrives in your personal one, even though both are connected.
