Reimbursements under an accountable plan
When an employee’s expense reimbursement is a business payment, and when Publication 463 says it is wages instead.
General information, not tax or legal advice. The three tests below are from IRS Publication 463 (2025). They describe accountable plans for employees. They are not a ruling that a particular lunch or mile qualifies.
Three tests, all required
Publication 463 states that expenses reimbursed under an accountable plan meet three conditions. The expenses must have a business connection: the employee paid or incurred deductible expenses while performing services as an employee. The employee must adequately account to the employer within a reasonable period of time. The employee must return any excess reimbursement or allowance within a reasonable period of time. Adequate accounting means a statement, account book, diary, or similar record entered at or near the time of the expense, with documentary evidence such as receipts. An excess reimbursement is any amount paid that is more than the business-related expenses the employee adequately accounted for.
The publication also describes a set of timing rules that are treated as a reasonable period: an advance within 30 days of the expense, an adequate accounting within 60 days after the expense was paid or incurred, and a return of excess within 120 days after the expense was paid or incurred. A periodic statement at least quarterly, complied with within 120 days of the statement, is also listed. Those day counts are the IRS safe-harbor description in that publication, not a promise that every other timetable fails.
How the books change
- Advance the money. Debit employee advances, an asset. Credit cash. This is not wage expense.
- Receive the accounting. Debit the expense accounts that match the receipts: travel, supplies, or the mileage amount you are reimbursing. Credit the advance. The mileage calculator only multiplies business miles by the 2026 rate of 72.5 cents. It does not prove the trip met the accountable-plan tests.
- Collect the excess. Debit cash for the unused advance. Credit the advance account. If the employee does not return it, Publication 463 treats the unreturned excess as paid under a nonaccountable plan.
- Do not run a nonaccountable payment through supplies. Amounts that fail the tests are wages. They belong in wage expense and on a W-2, not in “office supplies,” and they are subject to employment taxes. That is the publication’s distinction. This page does not compute the withholding.
Owners and contractors are a different paragraph
A sole proprietor does not reimburse themselves under an employee accountable plan. Money the owner takes is a draw or a contribution, unless the owner is on payroll because of the entity’s tax election. Publication 463 has a separate short section for independent contractors accounting to a client. Do not drop a contractor’s receipt into the employee advance account and call it the same plan. Contractor payments still follow the 1099 rules, including the $2,000 threshold for payments made in 2026.
