What is an accountable reimbursement plan?

An accountable reimbursement plan is an employer-run program that allows employees to be reimbursed for business expenses on a tax-free basis, as long as the plan meets specific IRS requirements.

When the rules are followed, reimbursements are excluded from the employee's wages and do not appear on their W-2.

What are the IRS requirements for an accountable plan?

The IRS requires three conditions be met for a plan to qualify as accountable.

  • Business connection: the expense must be ordinary and necessary for business

  • Adequate accounting: the employee must provide documentation within 60 days of incurring the expense

  • Return of excess: any reimbursement that exceeds the actual expense must be returned within 120 days

If any condition is not met, the reimbursement is treated as taxable wages.

What expenses qualify under an accountable reimbursement plan?

Common qualifying expenses include business travel, lodging, meals with a business purpose, mileage, office supplies, and work-related software or equipment.

How does an accountable plan differ from a nonaccountable plan?

Under a nonaccountable plan, reimbursements are added to the employee's taxable wages. They are subject to income tax withholding, Social Security, and Medicare taxes.

Nonaccountable plans are simpler to administer but cost both the employer and employee more in taxes.

What documentation do employees need to provide?

Employees must submit receipts, invoices, or other proof of the expense and its business purpose. For expenses over $75, a receipt is generally required.

Mileage reimbursements require a log showing dates, destinations, and business purposes. The standard IRS mileage rate for 2025 is 70 cents per mile.

What happens if reimbursements exceed actual expenses?

The employee must return the excess within 120 days. If they do not, the excess amount becomes taxable wages and must be included on their W-2.
