Do You Need Receipts for All Business Expenses? The $75 IRS Rule

No, you do not need receipts for all business expenses, but the IRS does expect some form of documentation for every deduction you claim. The dividing line for most purchases is $75: spend less than that on a single item and a dated log entry with the amount, place, and business purpose is enough. Spend more, book a hotel at any price, buy a gift, or drive your car for work, and you need an actual receipt or a detailed record. The rules are stricter than most business owners assume, and the biggest audit problems come not from a single missing receipt but from loose recordkeeping across the year.

The $75 Rule for Small Purchases

Treasury regulations let you skip the receipt for any business expense under $75, with one exception: lodging always needs documentation.¹ The threshold applies per transaction, not per day. A $40 lunch and a $50 cab ride are each under the limit individually, so neither requires a receipt even though you spent $90 that day.

Transportation expenses get an even broader pass. If a receipt is not readily available — tolls, subway fares, parking meters — you don’t need one regardless of amount.²

The $75 rule is a documentation shortcut, not a free pass. You are still claiming a deduction, and the IRS can still ask you to explain it. A specific log entry (“$45, March 12, Office Depot on Main Street, printer ink for client proposal”) does far more work than a vague note that says “office supplies.”

What Every Expense Record Must Show

Federal law requires you to keep records sufficient to support every item on your return.³ For a business expense, that means proving four things about each purchase:⁴

The amount
The date
The place
The business purpose

Business purpose is where people get sloppy. Writing “supplies” on a log entry is not substantiation. You need enough detail that an auditor can see why the expense was ordinary and necessary for your work.

Your records should also be contemporaneous, meaning created at or near the time you spend the money. The IRS considers a record timely when you have “full present knowledge” of the amount, time, place, and purpose, which realistically means logging it the same day or within a few days.⁴ Reconstructing a year’s worth of expenses during tax season is exactly the kind of thing that gets flagged.

The burden of proof for deductions falls on you. If an auditor questions a deduction and you can’t back it up, it gets disallowed. A narrow provision lets the burden shift to the IRS if you’ve maintained all required records, substantiated every item, and cooperated fully with the examination.⁵ Most taxpayers never reach that threshold in practice.

Expenses That Always Require Receipts

Section 274(d) of the tax code imposes strict substantiation rules on specific categories, and the $75 shortcut does not apply to any of them. No deduction is allowed unless you can produce adequate records showing amount, time and place, business purpose, and business relationship of anyone involved.⁶

Lodging

Hotel and lodging expenses always require a receipt or invoice, even if the nightly rate is under $75.¹ There is no standard allowance for lodging the way there is for meals, so your deduction is limited to what you actually spent.² Keep the itemized hotel folio rather than just the credit card charge; the folio separates room charges from personal costs like minibar purchases.

Business Meals and Travel

Business meals are deductible at 50% of cost. When you keep actual receipts, note who attended and the business topic discussed. A restaurant receipt with no context won’t survive an audit. As an alternative to tracking every meal, you can use the federal meals and incidental expenses rate for each day of business travel and skip individual meal receipts.² You still document the trip itself: dates, destination, and business purpose.

Business Gifts

You can deduct up to $25 per recipient per year for business gifts.⁷ Even at that low amount, you need a receipt plus a record of who received the gift, what it was, and the business reason for giving it. Gift deductions get scrutinized because they are easy to abuse.

Listed Property

If you use a vehicle, computer, or other equipment for both business and personal purposes, you need records that separate the two. For other listed property, that means a usage log showing business versus personal hours or days. Without that separation, the IRS will disallow the business portion of the deduction.

Vehicle Mileage Records

Claiming business use of a vehicle requires more detail than most other expenses. Whether you use the standard mileage rate of 72.5 cents per mile for 2026 or deduct actual costs, you need a contemporaneous log for every business trip.⁸ Each entry should include:

The date of the trip
The destination, with enough detail to identify the location
Miles driven for that specific trip
A concrete business purpose (“met with client Sarah Lee to review Q2 contract”), not just “business”
Beginning-of-year and end-of-year odometer readings for each vehicle used for business

Mileage is one area where the IRS is genuinely strict. A log created after the fact by going through your calendar and estimating trips is exactly the kind of reconstruction auditors are trained to spot. Apps that track trips via GPS in real time produce the strongest records because they are automatically contemporaneous.

Acceptable Substitutes for Paper Receipts

You don’t need to maintain a shoebox full of thermal paper. The IRS accepts several types of documentary evidence beyond register receipts, including canceled checks, credit card statements, bank records, and electronic payment confirmations. The record has to show the payee, the amount, and the date.⁹

A bank or credit card statement has a real limitation, though. It shows money left your account, but it doesn’t show what you bought. A $127.43 charge at a big-box store could be office supplies or birthday decorations. When the business purpose isn’t obvious from the statement, pair it with a diary entry or an itemized invoice.

Digital Storage

Digital copies of receipts carry the same weight as originals. The IRS allows electronic storage systems that ensure accurate transfer of the original information, maintain controls against unauthorized changes, and include an indexing system that lets you retrieve any document on request.¹⁰ Scan or photograph every receipt, organize the files so you can find them by date or vendor, and back them up. Once the digital version is verified and stored properly, you can shred the paper.

Most receipt-scanning apps handle the indexing and backup requirements automatically. The main risk with digital storage is neglecting backups. A crashed hard drive with no backup is the same as a box of receipts lost in a flood.

If You’ve Lost Receipts: The Cohan Rule

A legal doctrine called the Cohan Rule sometimes lets you deduct a reasonable estimate when you can prove you incurred a deductible expense but can’t establish the exact amount. A court can allow a partial deduction based on the available evidence.¹¹

The catch is significant. The Cohan Rule does not apply to expenses subject to the strict substantiation requirements of Section 274(d), which means travel, lodging, business gifts, and listed property like vehicles are all excluded.⁶ For those categories, if your records are gone, the deduction is gone.

Even where the Cohan Rule does apply — general office expenses, professional services, supplies — courts “bear heavily” against the taxpayer whose poor records created the problem. You might recover something, but expect every uncertainty to be resolved in the government’s favor. The rule is a safety net, not a strategy.

How Long to Keep Your Records

The general rule is three years from the date you file the return. That’s the standard window during which the IRS can audit you or you can file an amended return.¹² Several situations extend it:

Unreported income exceeding 25% of gross income: keep records for six years
Employment tax records: at least four years after the tax is due or paid, whichever is later¹³
No return filed or a fraudulent return: keep records indefinitely¹²

Property records, including anything related to a home office, depreciated equipment, or real estate, should be kept for as long as you own the asset plus at least three years after you file the return reporting its sale. The depreciation basis doesn’t reset each year, so tossing your original purchase records prematurely can cost you when you eventually sell.

What Happens If Your Records Fall Short

When the IRS disallows a deduction for lack of documentation, you owe the tax you should have paid, plus interest running from the original due date. On top of that, a 20% accuracy-related penalty applies to any underpayment caused by negligence or a substantial understatement of income.¹⁴ A “substantial understatement” means the tax you reported was off by the greater of 10% or $5,000, which is easier to hit than most people realize when multiple deductions are thrown out at once.

The penalty can be avoided if you show reasonable cause and good faith. Keeping a consistent expense log through the year, even an imperfect one, is far stronger evidence of good faith than scrambling to reconstruct records during an audit. The difference between a sloppy bookkeeper and a negligent taxpayer often comes down to whether any contemporaneous records existed at all.
