Business Expense Reimbursement Compliance Cheat Sheet 2026: IRS & GSA Numbers

What is the 2026 IRS standard mileage rate for business travel?

Numbers on this page last verified against the IRS and GSA sources below on October 12, 2026.

On December 29, 2025, the IRS announced an optional business mileage rate of 72.5 cents for the first half of 2026, up 2.5 cents from 2025. Announcement 2026-11 later raised it to 76 cents for qualifying expenses paid or incurred from July 1 through December 31. For employee mileage allowances, the higher amount applies only when both the allowance payment and the related expense fall on or after July 1; a later reimbursement for a first-half expense still uses the earlier rate. Source for the revision: IRS Announcement 2026-11, https://www.irs.gov/irb/2026-29_irb. Under a qualifying accountable plan, reimbursement at or below the standard mileage rate can substantiate the vehicle-cost amount; the employee still needs to log the date, destination, and business purpose of each trip, but not a fuel receipt for every mile.

• Business: 72.5¢/mile January 1–June 30; 76¢/mile July 1–December 31, 2026. Use the applicable expense period and the employee-allowance payment condition described above. The first-half amount was up 2.5¢ from 2025; the second-half revision is in Announcement 2026-11. Original first-half source: IRS, IR-2025-128 (December 29, 2025).
• Medical: 20.5¢/mile January 1–June 30; 23.5¢/mile July 1–December 31, 2026. Announcement 2026-11 raised the second-half rate; the first-half figure was down half a cent from 2025; the same rate applies to moving expenses, but that deduction is now limited to active-duty Armed Forces members relocating under orders and, newly for 2026, certain intelligence community members. Source: IRS, IR-2025-128 (December 29, 2025).
• 14¢/mile for charitable-organization use, unchanged from 2025. This rate is fixed by statute rather than adjusted annually for cost data the way the business and medical rates are, which is why it moves far less often. Source: IRS, IR-2025-128 (December 29, 2025).

The standard mileage rate is a safe harbor, not a legal ceiling. A company can reimburse actual vehicle costs instead, with receipts and a mileage log to back up the number, or set its own flat rate. What it cannot do is pay more than the IRS rate without documentation and still call the payment a nontaxable reimbursement: any amount paid above the accepted rate, without substantiation, is taxable wages to the employee.

What makes an expense reimbursement plan 'accountable' under IRS rules?

An allowance or reimbursement arrangement only keeps payments out of taxable wages if it meets all three requirements the IRS calls an "accountable plan." An arrangement that does not require substantiation or return of excess is nonaccountable, and its payments are wages. Under an otherwise accountable arrangement, an employee who fails to substantiate a particular expense or return excess generally has wages only for that unsubstantiated expense or unreturned excess. IRS Publication 5137 distinguishes these cases.

• Business connection. The reimbursement has to be for a deductible business expense the employee actually paid or incurred while performing services for the employer, not a stand-in for wages the employee would have received anyway.
• Substantiation. The employee must account for the amount, date, place, and business purpose of each expense to the employer within a reasonable period of time.
• Return of excess. The employee must return any amount received above the substantiated expenses within a reasonable period of time.

The IRS gives two built-in "safe harbor" timelines for the substantiation and return-of-excess legs. Under the fixed date method: an advance must be paid within 30 days of the expense, the employee must substantiate it within 60 days after it is paid or incurred, and any excess must be returned within 120 days, a maximum window of 150 days from advance to settlement. Under the periodic statement method: the employer sends at least a quarterly statement flagging amounts that need to be substantiated or returned, and the employee has 120 days from that statement to respond. Source: IRS Publication 5137, citing Treas. Reg. §1.62-2(g).

One trap catches otherwise well-run programs: a flat monthly car or phone allowance paid to every employee regardless of whether they actually incurred the expense is "wage recharacterization," not an accountable plan, even if some employees do spend the money on business costs. The IRS example in Publication 5137 involves a flat hourly travel allowance paid whether or not the employee traveled that day; because the amount does not track actual, substantiated expense, the whole allowance is taxable wages. A reimbursement tied to a business expense that was actually incurred and documented is not the same thing as a stipend. For the specific fields a claim needs to capture to stay auditable, see our reimbursement form guide.

When do you need a receipt to substantiate a reimbursed expense?

Under Treasury Regulation §1.274-5(c)(2)(iii), documentary evidence is generally required for lodging at any amount and other covered expenses of $75 or more. Exceptions include a qualifying per diem allowance for meals or lodging, nonlodging expenses below $75, and transportation charges when a receipt is not readily available. Amount, time, place, and business purpose must still be substantiated. A receipt exception does not make an otherwise nondeductible entertainment expense deductible.

The $75 threshold applies per expense, not per day or per trip. A finance team building an expense policy around this rule still needs a documented log for every sub-$75 item; "no receipt required" is not the same as "no record required." For the broader set of controls worth checking before employees move to corporate cards, see our expense report controls guide.

What per diem rates can substitute for actual-cost receipts in 2026?

Per diem rates let a company pay a fixed daily amount for lodging and meals without collecting a hotel folio and a stack of restaurant receipts for every trip; the flat rate itself satisfies the amount leg of substantiation, as long as time, place, and business purpose are still documented. Two federal agencies publish the numbers finance teams actually use.

• GSA standard CONUS rate, FY2026 (October 1, 2025 through September 30, 2026): $178/day total: $110 for lodging and $68 for meals and incidental expenses (M&IE). The $68 M&IE tier breaks down as $16 breakfast / $19 lunch / $28 dinner / $5 incidentals. Roughly 300 higher-cost cities and counties get a locality-specific rate above this floor; the standard rate applies to everywhere else in the continental US. Source: GSA, FY2026 CONUS Per Diem Rates release. For FY2027, October 1, 2026 through September 30, 2027, the standard CONUS total is $181: $113 lodging plus $68 M&IE, as announced in GSA Bulletin FTR 27-01. Check the GSA per diem lookup tool directly for a specific destination and travel date.
• IRS high-low substantiation method, through Sep 30, 2026: $319/day for travel to a high-cost locality, $225/day for any other CONUS locality. Of those totals, the portion treated as meals under §274(n) is $86 (high-cost) and $74 (other). Notice 2025-54 lists the qualifying localities and applicable dates using a $272 federal per diem threshold; follow its locality entries and seasonal windows; GSA nonstandard status alone does not qualify a destination. Source: IRS Notice 2025-54.
• IRS high-low substantiation method, October 1, 2026 through September 30, 2027: rises to $329/day high-cost and $230/day other CONUS; the meal portion stays at $86/$74, and the "high-cost" threshold rises to a $280 GSA per diem rate. Source: IRS Notice 2026-60.
• Special transportation-industry M&IE rate: $80/day for CONUS travel, $86/day for OCONUS travel, unchanged across both notice periods. Source: IRS Notice 2025-54 and Notice 2026-60.
• Incidental-expenses-only rate: $5/day, for an employee who incurs no meal cost but does have incidental expenses (tips to hotel staff, porters), unchanged across both notice periods. Source: IRS Notice 2025-54 and Notice 2026-60.

Rev. Proc. 2019-48 applies method consistency per employee: after high-low reimbursement for a traveler, other CONUS travel for that employee in the same calendar year must use high-low. OCONUS travel may use another permissible method. During October through December, keep the method used in the first nine months for that employee. An employer may retain the prior rates and locality list or adopt the updated ones for that quarter, but must apply its rate-and-list choice consistently to all employees reimbursed under high-low.

How much of a business meal is deductible in 2026, and what changed?

The general rule under IRC §274(n) has not moved: a business can deduct 50% of the cost of a meal with a client or a meal while traveling away from home, as long as the expense is substantiated and not lavish or extravagant under the circumstances.

Beginning in 2026, the employer deduction is generally unavailable for meals provided for employer convenience and meals at qualifying employer-operated eating facilities. The 2017 Tax Cuts and Jobs Act scheduled this change; the 2025 reconciliation act added limited exceptions, including certain restaurant and industry circumstances. IRS Publication 15-B explains the exceptions and confirms that employee income exclusions can still apply. Other meal categories, such as qualifying client or travel meals, generally retain the 50% limit; recreational events or other statutory exceptions require separate treatment.

For a company that has budgeted around a partial deduction for on-site meals, that is a real line-item change, not a rounding error. Whoever signs off on the 2026 T&E budget should account for it before the fact, not discover it at tax filing.

Can employees still deduct their own unreimbursed work expenses in 2026?

For the large majority of W-2 employees, no. The Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee business expenses from 2018 through 2025; the 2025 federal tax reconciliation act made that suspension permanent by amending IRC §67(h). An employee who pays for their own travel, mileage, or supplies without employer reimbursement generally has no way to recover that cost on their personal return anymore.

Source: Thomson Reuters Tax & Accounting, What OBBB Means for Your Clients’ Itemized Deductions, citing IRC §67(h).

A narrow set of employee categories keeps access to the deduction through Form 2106: Armed Forces reservists, qualified performing artists, fee-basis government officials, and employees with impairment-related work expenses. The elimination of this employee-side deduction does not remove otherwise allowable Schedule C business-expense deductions for self-employed workers.

Educators are a partial exception: the 2025 reconciliation act reclassifies unreimbursed classroom expenses as a non-2% itemized deduction starting in 2026, in addition to the above-the-line educator expense deduction, which rises to $350 for 2026 from $300 in 2025 under Rev. Proc. 2025-32 section 4.12. The same expense cannot be deducted twice; eligibility and qualified-expense rules apply.

The practical upshot for a finance team: because most W-2 employees cannot deduct their unreimbursed business expenses, getting the accountable-plan design right, and making sure legitimate expenses actually get reimbursed rather than absorbed by the employee, now carries more weight than it did before 2026.

What's the deduction limit for business gifts in 2026?

A business can deduct no more than $25 of the cost of a gift given, directly or indirectly, to any one person during the tax year. The cap is per recipient per year, not per gift or per occasion; two $30 gifts to the same client in one year are still capped at a combined $25 deduction.

• Incidental costs, engraving, packing, shipping, insuring, don’t count toward the $25 cap as long as they don’t add substantial value to the gift itself.
• Items costing $4 or less that carry the company’s name permanently engraved and are distributed broadly (branded pens, notepads) don’t count toward the per-person cap at all.
• If a spouse also gives a gift to the same recipient, the couple is treated as one taxpayer for the $25 limit, not two.
• Anything that could reasonably be classed as either a gift or entertainment (event tickets, for example) is generally treated under the entertainment rules, outside the ordinary gift limit; entertainment is generally nondeductible, subject to its own statutory exceptions.

The $25 figure looks like it should be indexed for inflation the way the mileage and per diem rates are. It isn't: the cap has been set at $25 since the rule was written decades ago, with no annual adjustment.

Frequently asked questions

Must employers follow the federal reimbursement amounts? Companies may reimburse actual costs or choose their own allowances. Federal allowances offer optional shortcuts to prove the amount. Excluding payments from wages still depends on the business purpose, timely documentation, and repayment of overpayments; an unsupported excess payment is generally wages.

How does a failed accountable-plan requirement affect payroll? Payments under a plan lacking the required safeguards are wages. For a compliant plan, an individual documentation or overpayment problem can cause only the affected sum to enter payroll income. Identify whether the defect is in the arrangement or in that employee payment before treating the whole payment as wages.

Can the October rate update be used for earlier trips? The new Notice 2026-60 amounts apply beginning October 1, 2026, not retroactively. For the final quarter, Revenue Procedure 2019-48 permits either old or new amounts and designated destinations, used consistently for the quarter without changing the prescribed method for the traveler. Check the notice period and transition election against the travel date.

Do employment status and tax filing change the published mileage amount? For 2026, the business allowance is 72.5¢ through June and 76¢ from July through December. Eligible self-employed filers select the amount for the period in which the expense was paid or incurred. Employer mileage allowances use the higher amount only if the employee receives the allowance in the second half and the trip expense was paid or incurred in that half; paying for an earlier trip later does not qualify it for the increase. An ordinary employee cannot write off mileage paid from personal funds. Workers eligible for Form 2106 have separate rules.

How does destination affect the daily allowance? GSA varies its allowances by location and fiscal-year period. The general continental-US allowance was $178 in FY2026 and is $181 for FY2027, starting October 1, 2026. The IRS high-low method uses its own notice list and date ranges; a GSA nonstandard locality does not automatically qualify as high-cost under that method.

How should you cite this page, and how current are these numbers?

Every figure on this page links to the IRS notice, IRS publication, or GSA release that set it; the citation format below covers the page as a whole.

Several of the numbers on this page change on the federal fiscal year boundary (October 1) rather than the calendar year, which means this page gets rechecked each time a new IRS per diem notice or GSA CONUS release publishes, in addition to the annual mileage-rate announcement each December. The "last verified" date at the top reflects the most recent check against the primary source, not the original publish date.
