An accountable plan is a company reimbursement policy that lets employers pay employees back for business expenses without treating those payments as taxable wages, as long as the plan follows IRS rules.
In a workplace setting, this usually applies when employees spend their own money on approved business costs and then submit those expenses for reimbursement. Common examples include travel, mileage, meals tied to business activity, or supplies purchased for work.
The main advantage is simple. Employees get reimbursed for legitimate work expenses, and those payments usually stay off payroll as taxable income.
How does an accountable plan work for employee reimbursements?
An accountable plan works through a structured reimbursement process. The employee pays for a valid business expense, documents it, and submits it to the employer. The company then reviews the request and reimburses the employee if it meets the policy rules.
Typical process:
Employee incurs a business related expense
Employee submits records such as receipts, mileage logs, or expense reports
Employer reviews the documentation
Employer reimburses the approved amount
Here is a simple example:
Step | What happens |
Expense occurs | Employee pays for a client lunch or work travel |
Documentation submitted | Employee provides receipts and business purpose |
Review completed | Employer confirms the expense qualifies |
Reimbursement made | Employee receives repayment outside taxable wages |
The key is documentation. Without it, the tax treatment can change fast.
What expenses can be reimbursed under an accountable plan?
Only ordinary and necessary business expenses should be reimbursed under an accountable plan.
Common reimbursable expenses include:
Business travel
Lodging for work trips
Business mileage
Meals related to work travel or business meetings
Office supplies bought for business use
Work related tools or equipment
Expense type | Example |
Travel | Airfare for a conference |
Transportation | Mileage for visiting a client site |
Meals | Meal during approved business travel |
Supplies | Printer ink purchased for office use |
Personal expenses do not qualify, even if they happen during work hours.
How does an accountable plan affect employee taxes and payroll?
A properly run accountable plan usually keeps reimbursements out of taxable wages. That means the payment is generally not subject to income tax withholding, Social Security tax, Medicare tax, or unemployment tax.
For payroll purposes, this matters because the reimbursement is not treated like regular compensation when the plan rules are followed.
Payment type | Tax treatment |
Accountable plan reimbursement | Usually not taxable |
Regular wages | Taxable through payroll |
Nonqualified reimbursement | May become taxable |
This is one reason employers often prefer accountable plans over informal reimbursement methods.
What are the IRS requirements for an accountable plan?
An accountable plan must meet three core requirements.
The expense must have a business connection
The employee must substantiate the expense within a reasonable time
The employee must return any excess reimbursement within a reasonable time
If one of these pieces is missing, the payment may no longer qualify for favorable tax treatment.
What is the difference between an accountable plan and a nonaccountable plan?
The difference comes down to documentation and tax treatment.
Plan type | Main difference |
Accountable plan | Requires business purpose, documentation, and return of excess amounts |
Nonaccountable plan | Does not fully meet IRS reimbursement rules |
With a nonaccountable plan, reimbursements are generally treated as taxable wages and included in payroll.
