Most guidance on business receipts is either vague ("keep everything") or wrong ("you never need receipts under $75"). The actual rules are narrower and more specific than either, and knowing them saves you from keeping paper you do not need — and from throwing away paper you do.
Here is what the IRS actually requires, what the $75 threshold really covers, and how long each type of record has to survive.
The short answer
You must keep records that support every item of income and every deduction on your return. For most business expenses that means a receipt or equivalent documentary evidence showing the amount, the date, the place, and the essential character of the expense. A receipt is generally not required for expenses under $75 — with a significant exception for lodging — but a written record of those four elements still is. Most records must be kept for at least three years.
The four elements every record must show
The IRS does not ask for a receipt because it likes paper. It asks because a deduction has to be provable on four points. Documentary evidence is ordinarily considered adequate when it shows all four:
| Element | What it means | Where it usually comes from |
|---|---|---|
| Amount | What you actually paid | The receipt total |
| Date | When the expense was incurred | Printed on the receipt |
| Place | The vendor, city, or location | Merchant name and address |
| Essential character | What it was and why it was a business expense | Usually missing — you add it |
The fourth element is where most records fail. A receipt from a hardware store proves you spent $214.60 at that store on 3 March. It does not prove the materials were for a client job rather than your own bathroom. That connection has to come from you — a note on the receipt, a line in an expense log, or a category assigned when you file it.
This is also why an unitemized card slip is weaker evidence than the full register receipt. The card slip shows a total; the itemized receipt shows what was bought. When a vendor hands you both, keep the itemized one.
The $75 rule — and what it does not do
The substantiation regulations under Internal Revenue Code section 274 provide that documentary evidence is not required for expenses under $75. This is the source of the widely repeated "you don't need receipts under $75" advice. Three things get lost in the repetition:
- Lodging is excepted. A hotel bill requires a receipt no matter how small the amount. There is no dollar floor for lodging.
- The record requirement does not go away. The threshold excuses the receipt, not the substantiation. You still need a written record of the amount, date, place, and business purpose — made at or near the time of the expense.
- It is a ceiling, not a target. Nothing stops an examiner from asking about a pattern of expenses that all happen to fall just under $75.
In practice, the threshold is most useful for small incidentals — parking, tolls, a box of supplies — where a contemporaneous log entry is genuinely easier than chasing paper. It is not a reason to stop capturing receipts, because a receipt takes seconds to photograph and settles all four elements at once.
What "adequate records" actually means
The IRS uses the phrase "adequate records" to describe the combination of a written record and documentary evidence. In practice that means two things working together:
- A timely record — an account book, diary, log, expense report, or digital equivalent, written at or near the time of the expense. Records reconstructed months later carry noticeably less weight.
- Documentary evidence — the receipt, paid bill, or similar proof backing up the entry.
"At or near the time" is the part people underestimate. A log written the same week is a contemporaneous record. A spreadsheet assembled the weekend before you file is a reconstruction, and it will be treated as one. The IRS guidance in Publication 463 is explicit that a contemporaneous record has greater value than one created after the fact.
How long to keep each type of record
The retention period is tied to the period of limitations — the window in which the IRS can assess additional tax or you can amend a return. It is not one number:
| Situation | Keep records for |
|---|---|
| Standard return, nothing unusual | 3 years from the date you filed |
| You omitted more than 25% of gross income | 6 years |
| You claimed a loss from worthless securities or a bad debt deduction | 7 years |
| You did not file a return | No limit — keep indefinitely |
| You filed a fraudulent return | No limit — keep indefinitely |
| Employment tax records | At least 4 years after the tax is due or paid, whichever is later |
| Property and equipment | Until the period of limitations expires for the year you dispose of it |
That last row catches people out. If you bought a $4,000 camera in 2020, depreciated it over several years, and sold it in 2026, the purchase receipt is still live evidence — it establishes your basis. Three years from the 2020 return is not the deadline; three years from the 2026 disposal is.
Our how long to keep receipts calculator works out the specific date for a given return and situation.
The categories with stricter rules
Four categories are governed by section 274(d), which imposes tougher substantiation than ordinary business expenses:
- Travel — including lodging and transportation away from home
- Meals
- Business gifts
- Listed property — which includes passenger vehicles
For these, an estimate is not acceptable no matter how reasonable it sounds. You need records establishing each element, and for meals and gifts that includes the business relationship of the people involved. "Client dinner" written on a receipt is not enough; the record should name who was there and what business was discussed.
This matters more than it sounds, because these four are the categories people most often lose paperwork for. If you are picking which receipts to be disciplined about, start here. Vehicle expenses in particular need a mileage log kept as you drive — see our guide to the Schedule C vehicle deduction for how the two methods compare.
Do you have to keep the paper?
No. The IRS has accepted electronically stored records since 1997 under Revenue Procedure 97-22, provided your system produces accurate, legible, complete copies that can be retrieved and reproduced when requested. We cover exactly what that procedure requires in does the IRS accept photos of receipts.
This is not a minor convenience. Most retail receipts are printed on thermal paper, which fades — sometimes to blank — well before the three-year retention window closes. An illegible receipt is not documentary evidence. Thermal receipts and what the IRS says covers why digitizing early is a documentation issue rather than a tidiness one.
What a bank statement does and does not prove
A common assumption is that a bank or credit card statement can stand in for receipts. It cannot, on its own. A statement establishes the amount and date, and usually the vendor — but it says nothing about what was purchased or why it was a business expense. That is two of the four elements, and the two that are hardest to reconstruct later.
There are narrow situations where a statement plus a contemporaneous note is workable, and situations where it never is. Can you use bank statements instead of receipts walks through both.
Receipts are not the only records you need
"Keep your receipts" is shorthand for a broader obligation. The requirement is to keep records that support every item of income, deduction, and credit on your return. Receipts cover one part of that. A complete set usually includes:
| Record type | What it supports | Typical source |
|---|---|---|
| Gross receipts | Income reported on the return | Invoices you issued, 1099 forms, deposit records, payment platform reports |
| Purchases and expenses | Deductions | Receipts, paid bills, invoices from suppliers |
| Mileage log | Vehicle deduction | Kept as you drive — date, destination, purpose, miles |
| Asset and equipment records | Depreciation and basis | Purchase invoice, improvement costs, disposal record |
| Employment records | Payroll and contractor payments | Payroll reports, 1099-NEC forms issued |
| Bank and card statements | Corroboration, not substitution | Downloaded from your bank |
The gaps that cause problems are rarely in the receipt pile. They are in the mileage log nobody kept and the asset records discarded three years after purchase but six years before disposal.
Mixed business and personal use
Many expenses are not wholly one thing or the other — a phone, home internet, a laptop, a vehicle. The deduction is limited to the business-use portion, and the allocation itself has to be supportable.
What that means in practice is that a receipt for the full amount is only the starting point. You also need a defensible basis for the percentage you claimed: a log of business versus personal mileage, a reasonable and consistently applied usage estimate for a phone, square footage for a home office. An allocation invented at filing time with nothing behind it is the weakest part of many returns.
Where an asset falls into the listed property category — vehicles most commonly — the substantiation rules are stricter still, and the usage records have to be contemporaneous.
The three mistakes that cost people deductions
- Capturing the receipt but not the reason. The amount and date are printed for you. The business purpose is the one element only you can supply, and it is the one that decays fastest from memory.
- Storing paper and assuming it will keep. Thermal receipts in a shoebox in a warm room are a countdown, not an archive.
- Reconstructing at filing time. A log built in April for the previous year is legally weaker than one built as you went, and it is where errors get introduced.
A system that satisfies all four elements
The requirement is not complicated once it is stated plainly: capture the receipt, record the business purpose, and store both somewhere legible and retrievable for at least three years.
That is the workflow ReceiptSync is built around. Photograph a receipt and the amount, date, and merchant are extracted automatically into your spreadsheet, with a category and note field for the business purpose — the element the paper never supplies. The image is preserved alongside the data, so the record stays legible long after the thermal print has faded. If you want the entries mapped to specific tax lines, the Schedule C category checker shows where a given expense belongs, and our Schedule C expense categories guide covers every line in detail.
