Reimbursement Receipt Requirements: The $75 Rule, Timing, and Records

Reimbursement receipt requirements come from two places at once: the IRS rules your employer has to satisfy to deduct what it pays you back, and your company’s own expense policy layered on top. At a minimum, a valid receipt should show the vendor, the date, an itemized breakdown of what you bought, the total paid, and how you paid. For travel, meals, gifts, and vehicle expenses, federal regulations require documentary evidence for any expenditure of $75 or more, and lodging always needs a receipt regardless of amount.¹ Miss those elements or miss the submission deadline, and a reimbursement that should have been tax-free can end up on your W-2 as taxable wages.

What Has to Be on the Receipt

The IRS doesn’t publish one universal checklist, but its guidance across publications consistently points to the same core elements: who you paid, how much, when, and what for.² A receipt that will pass review generally shows:

The vendor’s name and location — the business name and the address or city where the transaction happened.
The date of the purchase, so the expense can be matched to the right reporting period.
An itemized breakdown of what you bought, listed individually rather than as a lump sum. Auditors need to separate allowable business items from personal ones.
The total amount paid, including taxes and fees, so the reimbursement can be verified against what you spent.
The payment method, whether credit card, debit, cash, or something else. A missing payment indicator can delay processing or raise questions about whether the expense was already paid by the company.

Certain expense types carry sharper requirements. A hotel receipt needs to separate lodging from meals and phone calls. A restaurant receipt should show the number of people served, the date, and the amount. These aren’t arbitrary company preferences; they tie directly to the substantiation rules the IRS applies when it reviews deductions.³

Business Purpose

For travel, meals, and gifts, a receipt alone isn’t enough. You also need a record of why the expense was necessary for business. IRS Publication 463 requires that you document the business purpose, though the level of detail depends on context — if the purpose is obvious from the circumstances, a brief note will do.³ Most companies handle this through a line on the expense form where you write something like “client lunch to discuss Q3 deliverables” or “flight to Dallas for annual sales meeting.” Leaving that field blank is one of the fastest ways to get a claim kicked back.

Foreign Currency

If you travel internationally, your receipt will show the local amount. Your expense report needs to include the exchange rate used to convert to U.S. dollars. Some employers accept the rate from your credit card statement; others require a Treasury or Federal Reserve rate for the transaction date. Keep a record of the conversion source so the math can be verified.

The $75 Rule and When a Receipt Is Required

Federal regulations require documentary evidence — a receipt, paid bill, or similar proof — for any expenditure of $75 or more on travel, gifts, or car expenses. Lodging requires a receipt regardless of the amount. The only carve-out is for transportation charges where a receipt simply isn’t available, like a toll or a parking meter.¹

Two things to understand about the threshold. The $75 rule specifically applies to the categories covered by IRC Section 274 — travel, gifts, and vehicle expenses. It is not a blanket rule for all business purchases. And it sets an IRS floor, not a ceiling. Many employers require receipts for every purchase above $25, or for every purchase, period. Company policy will almost always be stricter than the IRS minimum, so check your expense policy before assuming a small purchase doesn’t need documentation.

For expenses under $75 other than lodging, you don’t technically need a traditional receipt, but you still need some documentation — a credit card statement, a written log, a digital record — that establishes what was purchased, when, how much it cost, and its business purpose.

Paper, Photo, or PDF

Original paper receipts are still common for in-person purchases, but the IRS has accepted electronic records as valid substitutes for decades. Under Revenue Procedure 97-22, electronically stored records satisfy federal recordkeeping requirements as long as the storage system maintains the integrity, accuracy, and reliability of the documents and produces legible copies on demand.⁴

Scanned images, mobile photos, PDF invoices, and records from expense management apps all qualify, provided every detail on the original is clearly readable. A blurry photo where the total is cut off won’t pass review. If your employer requires paper, check whether you also need to capture the back of the receipt, since some vendors print payment details or return policies there.

Whatever format you use, the digital copy has to stay accessible. The IRS requires that records be available for inspection for as long as they remain relevant to a tax return, which can be three to seven years or longer.⁵

Why Timing Turns Reimbursement Into Wages

Whether your reimbursement shows up as tax-free money or taxable wages depends on whether your employer runs what the IRS calls an accountable plan. This distinction matters more than most employees realize.

Accountable Plans

An accountable plan has three requirements: the expenses must have a business connection, you must substantiate them to your employer within a reasonable time, and you must return any excess reimbursement you received beyond what you actually spent.⁶ The IRS treats substantiation within 60 days of paying or incurring the expense as a safe harbor for “reasonable time.”⁷

When all three conditions are met, the reimbursement is excluded from your income. It won’t appear as wages on your W-2, and neither you nor your employer pays income tax or employment taxes on it.

Non-Accountable Plans

If any of the three requirements fails — you didn’t substantiate, you missed the deadline, or there’s no mechanism to return excess amounts — the arrangement is treated as a non-accountable plan. Reimbursements are included in your gross income, reported on your W-2 as wages, and subject to income tax withholding and employment taxes.⁷ A $500 reimbursement under a non-accountable plan gets taxed like $500 of salary. Careless documentation isn’t just a delayed check; it’s a higher tax bill.

When There Is No Receipt: Mileage and Per Diem

Not every reimbursable expense comes with a traditional receipt. The IRS provides standardized methods for two big categories.

Mileage

If you use your personal vehicle for business, your employer can reimburse you at the IRS standard mileage rate, which is 72.5 cents per mile for 2026.⁸ Instead of gas receipts and maintenance invoices, you keep a mileage log. A valid log records the date, starting point and destination, business purpose, and miles driven for each trip. You also need odometer readings at the start and end of the tax year, and whenever you begin or stop using the vehicle for business. The IRS expects the log to be kept at or near the time of travel; reconstructing a year of trips from memory in April won’t hold up.

Per Diem

For business travel involving lodging and meals, employers can use federal per diem rates instead of requiring itemized receipts. For the period beginning October 1, 2025, the high-low simplified rates are $319 per day in high-cost areas and $225 per day everywhere else. Of those amounts, $86 and $74 respectively are allocated to meals.⁹ When an employer uses per diem under an accountable plan, you don’t need individual meal or hotel receipts. You still have to substantiate the time, place, and business purpose of the travel.³

Lost or Incomplete Receipts

Receipts get lost, fade, or never printed in the first place. That doesn’t automatically mean the expense is unreimbursable, but your options narrow depending on the type of expense.

Publication 463 addresses this directly: if you don’t have complete records to prove an element of an expense, you can substitute your own written or oral statement containing specific details, combined with other supporting evidence sufficient to establish the missing element.³ A credit card statement showing the charge, a bank record, a confirmation email, or a written account of what happened can fill the gap. The more corroborating evidence you assemble, the stronger your position.

A separate doctrine called the Cohan rule, from a 1930 court case, allows taxpayers to estimate expenses when documentation is missing. It comes with two important limits. You still have to prove the expense actually happened; the rule only helps with the exact amount, not the existence of the cost. And it does not apply to travel, meal, gift, or vehicle expenses, because IRC Section 274 imposes strict substantiation requirements that override the estimation approach.¹⁰ For office supplies or general business purchases, estimation might save you. For a business dinner or a flight, you need real documentation.

The best defense against lost receipts is capturing them immediately. Snap a photo the moment you get the receipt, or use an expense app that imports transactions from your credit card. Thermal paper receipts fade within months. By the time you need documentation for an audit, the original may be blank.

How Long to Keep Them

The IRS requires you to keep records as long as they could be relevant to a tax return. For most people, that means at least three years from the date the return was filed. Several situations extend the window:¹¹

Three years is the general retention period for supporting documents tied to a tax return.
Four years applies to employment tax records, kept at least four years after the tax was due or paid, whichever is later.
Six years applies if unreported income exceeds 25% of the gross income shown on the return, or is attributable to foreign financial assets exceeding $5,000.
Seven years applies if a claim is filed for a loss from worthless securities or a bad debt deduction.
Indefinitely: if no return was filed or a fraudulent return was filed, there is no time limit on IRS assessment.

Keeping receipts for at least six years covers most scenarios. Digital storage makes this easier than it used to be; a well-organized cloud folder survives the office moves and cleanouts that destroy paper files.¹²

What If Your Employer Won’t Reimburse

Federal law does not require private employers to reimburse employees for business expenses. Roughly a dozen states and several cities do. These laws generally require employers to cover necessary expenses employees incur while performing their job duties, with reimbursement deadlines that typically start at 30 days after the employee submits documentation. Some of these laws are broad enough to cover remote work costs like internet service and phone bills. If your employer has no reimbursement policy, check whether your state has a mandatory reimbursement statute — you may have a legal right to recover those costs regardless of what the company says.
