Accountable plans remain the most tax-efficient way for nonprofits to reimburse employee business expenses. When properly structured and implemented, these plans allow reimbursements to be excluded from employees’ taxable income and save payroll taxes for the organization.

Eligible expenses

To qualify under an accountable plan, reimbursements must meet three core IRS criteria: 1) they must be for expenses that have a legitimate business purpose, 2) those expenses must be adequately substantiated, and 3) any excess advances must be returned within a reasonable period. “Reasonable” is generally interpreted under IRS safe-harbor rules, such as substantiating expenses within 60 days and returning excess amounts within 120 days.

Qualifying expenses commonly include business-related travel, meals, lodging, transportation, professional dues, continuing education, and necessary tools, or supplies. Home office expenses may qualify in limited circumstances, but only when they’re directly tied to the employer’s business needs and not personal use.

A formalized policy

Although the IRS doesn’t require accountable plans to be in writing, a documented policy is generally recommended—especially for nonprofits subject to heightened governance and audit scrutiny. A written plan helps demonstrate compliance and supports internal controls.

It’s also critical that reimbursements are clearly separated from wages. Accountable plan payments must be made in addition to regular compensation and can’t be used to recharacterize taxable wages as tax-free reimbursements. Misclassification can trigger payroll tax liabilities and penalties.

Recordkeeping standards

The IRS also requires employers with accountable plans to keep good records for expenses that are reimbursed. For each expense, to the extent applicable, documentation should include the:

• Amount and date,
• Business purpose,
• Location (for travel-related costs), and
• Business relationship of any individual involved.

Receipts are generally required for lodging and for any expense of $75 or more. If your nonprofit uses per diem rates for travel, receipts aren’t required—but ensure that your per diems align with current federal rates and that employees still substantiate the time, place, and business purpose of travel.

Integrating your plan with digital expense reporting tools can improve compliance, streamline approvals, and strengthen audit trails. Nonprofits should periodically review their accountable plans to ensure they remain aligned with IRS regulations, state laws, and organizational policies.

Establishing (or refining) an accountable plan

A well-structured accountable plan can provide tax benefits for nonprofit organizations and their employees. It can also help ensure reimbursements are handled consistently, transparently, and in line with IRS expectations.

If your nonprofit hasn’t reviewed its reimbursement practices recently, now is a good time to do so to assess whether your current policy meets accountable plan requirements.
