What Is an Accountable Plan, And Why Does Your Nonprofit Need One?
If your organization reimburses employees for business expenses like mileage, supplies, travel, home office costs, you need to know about Accountable Plans. Used correctly, they protect both your employees and your organization from unnecessary tax liability. Used incorrectly (or not at all), those reimbursements can become taxable income for your staff and a record keeping headache for you.
Here's what you need to know.
What Is an Accountable Plan?
An Accountable Plan is a formal reimbursement arrangement that meets IRS fringe benefits guidelines for treating employee expense reimbursements as tax-free. The name comes from the idea of accountability: employees must account for their expenses with documentation, and any excess reimbursement must be returned to the organization.
When a reimbursement is made under an Accountable Plan, it is not reported as wages on the employee's W-2. That means no income tax, no payroll tax, and no FICA — for your employee or your organization.
Without an Accountable Plan, the IRS treats expense reimbursements as supplemental wages. That money gets added to the employee's taxable income, reported on their W-2, and subjected to payroll taxes on both sides. What was meant to be a simple reimbursement becomes a tax event for everyone.
The Three IRS Requirements
For a reimbursement arrangement to qualify as an Accountable Plan, it must satisfy three rules:
1. Business Connection The expense must have a legitimate business purpose. Reimbursable expenses might include mileage driven for organizational business, conference registration fees, supplies purchased for a project, client meal costs, or a portion of a home internet bill for remote employees.
2. Substantiation Employees must document their expenses with receipts, logs, or other records. This typically means submitting receipts along with an expense report that includes the date, amount, business purpose, and (for meals or travel) the names of who was present and why. The IRS generally requires substantiation within a reasonable period — 60 days is the common standard.
3. Return of Excess If an employee receives an advance or allowance that exceeds their actual documented expenses, the difference must be returned to the organization within a reasonable period (120 days is typical). Any amount not returned becomes taxable compensation.
How to Use an Accountable Plan
Setting up and running an Accountable Plan doesn't have to be complicated. The essentials are:
Put it in writing. The plan should be a formal written document that describes what expenses are reimbursable, how employees submit requests, documentation requirements, and the timeline for submitting and returning excess funds. This document is your foundation.
Use a consistent expense report template. Employees should submit the same basic information every time: date, vendor, amount, business purpose, and any required receipts. A simple, standardized form makes this routine for staff and easy to review for your finance team.
Review and approve before reimbursing. A supervisor or finance staff member should review expense reports for completeness and eligibility before issuing payment. This keeps the process clean and defensible.
Keep records. Retain expense reports and supporting receipts in accordance with your document retention policy. The IRS can audit payroll-related records for several years, so organized recordkeeping matters.
Reimburse promptly. Timely reimbursement encourages compliance and keeps employees from feeling like they're personally financing the organization's operations.
The Tax Benefits (For Everyone)
Accountable Plans are one of the most straightforward tax-saving tools available to nonprofits and small employers. Here's what's at stake:
For employees: Reimbursements made under an Accountable Plan are excluded from gross income. Employees don't owe income tax or payroll taxes on money they're being repaid for legitimate work expenses. Without a plan, that same reimbursement shows up as taxable income on their W-2.
For employers: Reimbursements under an Accountable Plan are not subject to payroll taxes (Social Security, Medicare, FUTA). For a small organization reimbursing staff for regular expenses, this can represent meaningful savings over the course of a year. And because reimbursements aren't wages, they don't inflate your payroll figures.
For nonprofits specifically: Tax-exempt status doesn't make payroll taxes go away. Nonprofits still pay employer-side FICA and FUTA just like any other employer. An Accountable Plan helps stretch your program dollars further by reducing unnecessary payroll tax exposure on expense reimbursements.
Common Expenses Covered
Accountable Plans can cover a wide range of legitimate business expenses, including:
Mileage and travel — using the IRS standard mileage rate or actual costs
Supplies and equipment — purchased for organizational use
Professional development — conferences, training, books, or dues
Meals — when there is a clear business purpose and proper documentation
Home office and remote work costs — a portion of internet or phone bills, if the employee works remotely
Client or donor-related expenses — within your organization's policies
The key is that every reimbursed expense must tie back to a genuine business purpose and be properly documented.
