What the IRS Actually Needs From Your Receipts (Boring But Free)

Most receipt advice you'll find online is from accounting firms trying to sell you software.

This post is from the IRS itself. Specifically, IRS Publication 583 (Starting a Business and Keeping Records), Publication 463 (Travel, Gift, and Car Expenses), Publication 17 (Your Federal Income Tax), and a couple of revenue procedures that govern digital storage.

Boring sources. Free to read. They tell you exactly what a receipt has to show, how long you have to keep it, and what "adequate records" means in plain English.

If you've been overthinking your filing system, the actual rules are simpler than receipt-app marketing makes them sound.

The 5 things every receipt must show

Per Publication 583, a receipt for a business expense has to substantiate five elements:

1. The amount. What did you pay.
2. The date. When did you pay it.
3. The vendor. Who did you pay.
4. What was purchased. A description of the product or service.
5. The business purpose. Why this expense relates to your business.

The first four are usually printed on the receipt itself. The fifth is the one that trips people up. The IRS doesn't require the business purpose to be on the receipt, but it does require you to be able to explain it. A meal at a restaurant is fine; a meal at a restaurant where you discussed a contract with a client and can name the client is what you actually need.

For most software and infrastructure expenses (your AWS bill, your Vercel bill, your Notion subscription), the business purpose is obvious from the vendor name. You don't need a separate note. For meals, travel, and gifts, you do.

The $75 rule

There's a specific threshold most founders don't know about. Per Publication 463, expenses under $75 generally don't require a receipt. You can substantiate them with other records (a bank statement, a card statement, a contemporaneous note in a logbook).

The exceptions are lodging (always need a receipt regardless of amount) and certain transportation costs.

In practice this means: that under $10 ChatGPT subscription doesn't legally require you to keep the receipt, and neither does an under $50 Uber to a client meeting. But you still need to substantiate that it was a business expense, and the easiest way is to keep the receipt anyway.

The $75 threshold has been in place since the early 2000s and hasn't been adjusted for inflation. Worth being aware of, but practically: just keep all the receipts. The marginal cost is zero if you've automated filing.

The 3-year, 6-year, 7-year retention rules

This is where most founders get confused. The IRS has multiple retention windows depending on the type of record.

3 years - the standard. The IRS has 3 years from the date you filed your return to assess additional tax. Keep records for 3 years after filing for any year where you reported income normally.

6 years - if you understated income by more than 25%, the assessment window doubles to 6 years. So if there's any chance of a reporting error, 6 years is the safe minimum.

7 years - if you claimed a loss from worthless securities or bad debt deduction, 7 years.

Indefinitely - if you didn't file a return, or filed a fraudulent return. Don't do this.

Until you sell - records related to property (depreciation, basis adjustments) need to be kept until the period of limitations expires for the year you dispose of the property. So if you bought a $4,000 laptop in 2024 and depreciated it over 5 years, the receipt has to live until at least 2030, possibly later.

The pragmatic answer for solo founders: keep everything for 7 years minimum. Storage is free. Drive doesn't charge you per file. There's no reason to delete anything.

The IRS source for this is Publication 583, page 13: "Period of Limitations." Worth a 5-minute read once.

What "adequate records" actually means

The IRS uses the phrase "adequate records" in multiple publications. It's not legally defined to a single standard, but the working definition combines guidance from Pub 583, Pub 463, and Treasury Regulation 1.6001-1.

Adequate records means:

• Permanent. Not on a Post-it that fades. Digital files count if they're stored durably.
• Accessible. You can produce them on demand within a reasonable time (typically 30 days for an audit response).
• Organized. The IRS uses the word "orderly" - meaning the auditor shouldn't have to dig through your inbox to find what they asked for.
• Substantiating. They prove the five elements above.

A folder of PDFs in Google Drive, organized by vendor and year, hits all four. A 12,000-email Gmail inbox with no labels does not - "accessible" implies you can find specific records on request, and "organized" requires more than full-text search.

This matters because if the IRS audits you and you can't produce records that meet the standard, they can disallow the deduction. You eat the tax plus penalties. The whole point of filing receipts is that you never end up in this situation.

Travel, meals, and entertainment - special rules

Post-TCJA (the Tax Cuts and Jobs Act, effective 2018), entertainment is no longer deductible. Meals are mostly 50% deductible if business-related. Travel is generally 100% deductible.

But all three categories have heightened substantiation requirements per Publication 463. For each meal expense over $75, you need:

• The amount of the expense
• The time and place
• The business purpose
• The business relationship of the people present

That last one is the kicker. For a meal with a client, you need to record (somewhere, doesn't have to be on the receipt itself) who you ate with and what business you discussed. A Google Calendar entry from that day works. A sticky note in your wallet works. An email confirmation works.

This is the one area where the receipt alone isn't enough. Receipt + context. The receipt goes in your filing system; the context can live in your calendar or notes.

For travel, the substantiation is similar. Hotel folio (always required regardless of amount), flight confirmation, the dates and business reason for the trip. If you're a freelancer who takes occasional client trips, this is straightforward. If you're a digital nomad who tries to deduct half your nomadic life, the substantiation gets harder.

Digital storage rules - Rev. Proc. 97-22 and 98-25

This is the question every founder asks: "Can I throw away the paper receipts if I have digital copies?"

Answer: yes, since 1997.

Revenue Procedure 97-22 establishes that taxpayers can store records electronically as long as the system meets certain requirements. The IRS updated this in Rev. Proc. 98-25 specifically for "automatic data processing" records.

The requirements, simplified:

• The digital record must be a true copy of the original, with all relevant data intact.
• The system must be capable of indexing, retrieving, and reproducing the records on demand.
• You must keep the records for the same retention period as you would the originals.

PDFs from email vendors (Stripe, AWS, etc.) qualify automatically - they're already digital originals. PDFs you scanned from paper receipts qualify if you scanned them properly (legible, complete, not just a photo of a folded receipt).

What doesn't qualify: a screenshot of an email confirmation that doesn't include the full transaction details. A hand-typed summary of a receipt. An OCR'd CSV without the original PDF backup.

The IRS specifically allows electronic storage. You don't need to keep paper copies. You don't need a special "audit-compliant" storage system. A Drive folder is fine, provided you can find specific records on demand.

What this means for your filing system

The IRS doesn't care what app you use. It cares that you can produce the requested records, organized, in a reasonable time.

The minimum viable system:

1. Receipts stored as PDFs (the original from the vendor email).
2. Organized by vendor and year, so you can find "all 2024 AWS invoices" in 30 seconds.
3. Backed up so you don't lose them in a hard-drive crash.
4. Retained for 7 years minimum.

That's it. No OCR. No categorization. No special compliance software. The IRS rules don't mandate any of those things.

This is also exactly what AutoFileEmail produces. New email with attachment arrives, attachment lands in /AutoFileEmail/{vendor-domain}/{year}/{month}/. PDFs are the original from the vendor. Folder structure is vendor + year. Drive's own retention is effectively unlimited as long as you keep the account.

The system that meets every IRS requirement happens to be the simplest possible system. Which is good news, because the alternative - paying $30 a month for OCR you don't need - doesn't make you any more compliant. It just makes you poorer.

TL;DR

The IRS rules for receipts are boring and free. Five elements per receipt, 7-year retention, digital is fine since 1997, organized by vendor and year is "adequate."

AutoFileEmail produces a Drive folder that meets every one of these requirements out of the box. No OCR, no AI, no per-receipt fees.

Free for one inbox. Connect Gmail and Drive in two minutes. The IRS won't care which app you used. They'll care that you can produce the folder.

The receipts most founders fail to produce in an audit aren't missing because the filing system was wrong. They're missing because there was no filing system. Have one. The IRS doesn't ask for more than that.
