Free expense reimbursement policy templates for small business: IRS accountable-plan ready, with expense report form, mileage, and remote versions. DOCX.
Five free expense reimbursement templates for small business, built around IRS accountable-plan rules that keep reimbursements tax-free: a full policy, an expense report form, a mileage policy, a remote and home-office version, and an acknowledgment form. Download as DOCX.
An expense reimbursement policy sets out which business expenses your company pays back to employees and how. Done well, it does something most templates gloss over: it keeps those reimbursements tax-free by meeting IRS accountable-plan rules. Get that structure right and reimbursements are excluded from wages; get it wrong and they can become taxable income for everyone involved. For a small business without a finance team, that difference is the whole point.
These five templates cover it end to end: a full expense reimbursement policy built around the accountable-plan rules, the expense report form employees submit, a mileage policy, a remote and home-office version, and an acknowledgment form. Each downloads as a Word document, free and without an email. Because expenses are one piece of your broader people operations, the policy works alongside the HR policy manual.
TL;DR
An expense reimbursement policy defines which business expenses an employer pays back and how. Structured to meet IRS accountable-plan rules (business connection, substantiation, return of excess), reimbursements stay tax-free; otherwise they become taxable wages. Some states, notably California, Illinois, and Massachusetts, require reimbursing necessary and remote-work expenses. Download five free templates as DOCX, including an expense report form and mileage and remote versions, then have a tax or legal advisor review. This is general information, not legal or tax advice.
What an Expense Reimbursement Policy Is
An expense reimbursement policy is a written set of rules for paying employees back for business expenses. It defines what is reimbursable, the limits, the documentation required, the deadline to submit, and the approval and payment workflow, and it is structured so reimbursements meet IRS accountable-plan rules and stay tax-free.
It usually travels with an expense report form, the document employees fill in to claim their costs, and the two are designed together. The policy sets the rules; the form captures the claim. For a small business, having both written down prevents disputes, controls spending, keeps reimbursements non-taxable, and creates the paper trail you need if the IRS or an employee ever asks.
The IRS Accountable Plan
The most important part of an expense reimbursement policy is the IRS accountable plan, because it determines whether reimbursements are tax-free. An accountable plan has three conditions, and meeting all three keeps reimbursements out of taxable wages.
1. Business connection
The expense must have a genuine business purpose, incurred by the employee while doing their job for the company. Personal costs do not qualify.
2. Adequate substantiation
The employee must document each expense, including the amount, date, place, and business purpose, and submit it within a reasonable time, usually with receipts.
3. Return of excess
Any advance or payment beyond the substantiated expense must be returned within a reasonable time, generally within 120 days of the expense.
Accountable Plan: Tax-Free or Taxable
Meet all three conditions and reimbursements are excluded from the employee's wages and exempt from income and employment taxes. Fail any one and the payments become taxable wages subject to withholding for the employee and payroll taxes for the employer (IRS). This is why the accountable-plan structure is the heart of the policy.
A safe-harbor guideline helps: employees submit expenses within 60 days and return any excess advance within 120 days, with advances paid no more than 30 days before the expense. Building these timings into the policy keeps the plan accountable without micromanaging every claim.
What to Reimburse, and What Not To
A clear policy spells out which expenses qualify and which do not, so employees know before they spend. The exact list is a business decision, but the categories below are the common starting point, and writing them down prevents most disputes.
Typically reimbursable
Travel: economy airfare, lodging, rental car
Meals while traveling (receipt or per diem)
Business mileage in a personal vehicle
Approved supplies, tools, and equipment
Business phone and internet for remote work
Approved conference and training fees
Typically not reimbursable
Commuting between home and the regular workplace
Personal entertainment, minibar, and movies
Traffic and parking fines
Alcohol, unless pre-approved client entertainment
Spouse or companion travel and upgrades
Personal items and personal-property losses
The non-reimbursable list matters as much as the reimbursable one. Commuting is the classic example: travel between home and the regular workplace is not a business expense, while travel between work sites or to a client is. Spell out the edge cases you expect, and require pre-approval for anything unusual.
State Reimbursement Laws
Federal law does not broadly require reimbursing business expenses, but several states do, and this is where small employers most often get caught, especially with remote work. The obligation follows the employee's work location, so one remote hire can bring a new state's rules into play.
Mandate States Reach Remote Costs Too
California, Illinois, and Massachusetts, among others, require reimbursing necessary business expenses. California is especially broad: it requires reimbursing a reasonable percentage of a personal phone or internet bill for remote work, even on an unlimited plan, and even when the employee works from home by choice or a government order. Confirm the rule for every state where your employees work. This is general information, not legal advice.
Because remote work spreads your team across states, the safest approach is to check the reimbursement rule for each state where an employee actually works, not just where the company is based. The remote and home-office template is built around exactly these mandates.
Which Template Should You Use?
Start with the full policy and its report form, then add the focused versions you need. The mileage policy suits teams whose main expense is driving; the remote and home-office version is essential if you employ people in reimbursement-mandate states; and the acknowledgment form pairs with any of them.
Expense Reimbursement Policy
The flagship
The full policy: purpose, IRS accountable-plan compliance, eligible and non-reimbursable expenses, mileage and per diem, documentation, approval workflow, return of excess, state law, and an acknowledgment.
Expense Report Form
The companion form
The fill-in form employees use to submit expenses: itemized lines, a mileage section, totals with advances deducted, and employee, manager, and finance sign-off. Pairs with the policy.
Mileage Reimbursement Policy
Vehicle use
A focused policy for business use of a personal vehicle: the IRS rate, what counts as business mileage versus commuting, documentation, and a California note. For teams that mainly reimburse driving.
Remote / Home-Office Policy
Distributed teams
A policy for remote-work expenses, built around the state-law mandates that make this area risky: California, Illinois, and Massachusetts require reimbursing necessary remote costs like phone and internet.
Acknowledgment Form
Ready to sign
A standalone form to record that each employee received and agreed to the expense policy, designed to be collected at onboarding and after updates.
Match the Template to Your Situation
Setting up reimbursements: the full Expense Reimbursement Policy plus the Expense Report Form. Mostly reimbursing driving: add the Mileage Policy. Employing remote workers, especially in CA, IL, or MA: add the Remote / Home-Office Policy. Then use the Acknowledgment Form, fill in your limits and deadlines, add your state specifics, and have a tax or legal advisor review before adopting.

The full policy: purpose, IRS accountable-plan compliance, eligible and non-reimbursable expenses, mileage and per diem, documentation, approval workflow, return of excess, state law, and an acknowledgment. The foundation to adapt.
Expense Reimbursement Policy
EXPENSE REIMBURSEMENT POLICY
[Company Name]
Effective date: _ Policy owner: __
Last reviewed: _
1. PURPOSE AND SCOPE
This policy explains how [Company Name] reimburses employees for reasonable,
necessary business expenses. It applies to all employees who incur approved business
expenses. The goal is to reimburse legitimate costs promptly while meeting IRS
accountable-plan rules so that reimbursements are not treated as taxable wages.
2. ACCOUNTABLE PLAN (WHY THIS KEEPS REIMBURSEMENTS TAX-FREE)
[Company Name] operates an accountable plan under IRS rules. To keep reimbursements
tax-free, every expense must meet three conditions:
1. Business connection: the expense was incurred doing your job for the company.
2. Substantiation: you submit adequate documentation (receipts, purpose, date,
amount) within a reasonable time.
3. Return of excess: you return any advance or over-payment that exceeds your
substantiated expenses within a reasonable time.
If these conditions are met, reimbursements are excluded from your taxable wages. If
they are not met, the payment may become taxable income subject to withholding.
3. ELIGIBLE (REIMBURSABLE) EXPENSES
•Travel: economy airfare, standard lodging, standard rental car, taxi or rideshare
•Meals while traveling on business (by receipt or per diem, see section 5)
•Mileage for business use of a personal vehicle (see section 5)
•Office supplies and required tools or equipment, when approved
•Business phone and internet for remote work, per company practice and state law
•Conference, training, and professional membership fees, when approved
4. NON-REIMBURSABLE EXPENSES
•Personal entertainment, minibar, and in-room movies
•Commuting between home and your regular workplace
•Traffic or parking fines
•Alcohol, unless pre-approved as client entertainment
•Personal items, spouse or companion travel, and unauthorized upgrades
•Losses of or damage to personal property
5. MILEAGE, PER DIEM, AND LIMITS
Mileage: business use of a personal vehicle is reimbursed at the current IRS standard
business mileage rate in effect at the time of travel. [Confirm the live IRS rate; it
is updated each year.]
Per diem (optional): meals and incidental expenses may be reimbursed at a set per diem
rather than by receipt. Many employers use the GSA per diem rates as a benchmark, with
the first and last travel day at a reduced rate. [Set your per diem approach here.]
Category limits: [Set any per-category caps, for example a nightly lodging cap or a
daily meal cap, and note when pre-approval is required.]
6. DOCUMENTATION AND SUBMISSION
Submit an expense report with itemized receipts, the business purpose, date, and
amount for each expense. Submit within [30 / 60] days of incurring the expense.
Receipts are required for expenses of [$25] or more, and for all lodging and airfare
regardless of amount.
7. APPROVAL AND REIMBURSEMENT WORKFLOW
1. Employee submits the expense report with receipts by the deadline.
2. Manager reviews for policy compliance and business purpose and approves or returns
it.
3. Finance verifies documentation and processes payment.
4. Reimbursement is paid within [X] days, typically with or shortly after payroll.
8. ADVANCES AND RETURN OF EXCESS
Where advances are permitted, any amount exceeding substantiated expenses must be
returned within a reasonable time, generally within 120 days of the expense, so the
plan stays accountable.
9. STATE LAW
Some states require employers to reimburse necessary business expenses. California,
Illinois, and Massachusetts, among others, have specific reimbursement mandates that
can include mileage, phone, internet, and home-office costs. [Confirm the rules for
every state where your employees work, including remote employees, and adjust this
policy accordingly.]
10. NON-COMPLIANCE
Expenses that do not follow this policy may not be reimbursed. Submitting false or
inflated expenses is grounds for disciplinary action up to and including termination.
ACKNOWLEDGMENT
I acknowledge that I have received and read the [Company Name] Expense Reimbursement
Policy and agree to follow it.

DISCLAIMER: This is a sample template for general informational purposes only and is
not legal or tax advice, and not a guarantee of compliance. IRS rules and state
reimbursement laws vary and change. Confirm current IRS accountable-plan and mileage
guidance and your state requirements, and have this policy reviewed by a qualified
tax or legal advisor before adopting it.
Template 2: Expense Report Form
The companion form employees use to submit expenses: itemized lines, a mileage section, totals with advances deducted, and employee, manager, and finance sign-off.
A focused policy for business use of a personal vehicle: the IRS rate, what counts as business mileage versus commuting, documentation, and a California note. For teams that mainly reimburse driving.
Mileage Reimbursement Policy
MILEAGE REIMBURSEMENT POLICY
[Company Name]
Effective date: _
1. PURPOSE
This policy explains how [Company Name] reimburses employees for business use of a
personal vehicle. It is designed to meet IRS accountable-plan rules so that mileage
reimbursements are not treated as taxable wages.
2. RATE
Business miles are reimbursed at the current IRS standard business mileage rate in
effect at the time of travel. The IRS updates this rate each year, so confirm the
current rate rather than assuming last year's. [State your rate or reference the live
IRS rate here.] The standard rate is intended to cover fuel, maintenance,
depreciation, insurance, and registration, so those costs are not reimbursed
separately.
3. WHAT COUNTS AS BUSINESS MILEAGE
Reimbursable: travel between work sites, to client or customer locations, to the
airport for business travel, and other business errands.
Not reimbursable: normal commuting between home and your regular workplace.
4. DOCUMENTATION
For each trip, record the date, starting point and destination, business purpose, and
miles driven. Submit your mileage log with your expense report within [30 / 60] days.
A contemporaneous log (kept at the time of travel) is the strongest documentation.
5. STATE LAW
Some states require reimbursement of vehicle expenses. In California, for example,
paying the IRS standard mileage rate generally satisfies the employer's obligation
for vehicle costs, though employees may show actual costs were higher. [Confirm the
rule for every state where your employees drive for work.]

Remote / Home-Office Expense Policy
REMOTE / HOME-OFFICE EXPENSE POLICY
[Company Name]
Effective date: _
1. PURPOSE
This policy explains how [Company Name] handles expenses for employees who work
remotely, including home-office costs. It is designed to meet IRS accountable-plan
rules and applicable state reimbursement laws.
2. REIMBURSABLE REMOTE EXPENSES
Subject to approval and the limits below:
•A reasonable portion of business phone and internet used for work
•Required office supplies and equipment for the role
•[Any stipend or specific items your company provides]
3. STATE LAW IS CENTRAL FOR REMOTE WORK
Several states require employers to reimburse necessary remote-work expenses.
California, Illinois, and Massachusetts, among others, mandate reimbursement, and in
California a reasonable percentage of a personal phone or internet bill must be
reimbursed even on an unlimited plan. Reimbursement can be required even when an
employee works from home by choice or by government order. [Confirm the rule for each
state where your remote employees live and work, since obligations follow the
employee's work location.]
4. HOW REIMBURSEMENT WORKS
[Choose an approach and describe it: a reasonable-percentage reimbursement of actual
phone and internet bills, a fixed monthly stipend, or actual-cost reimbursement with
receipts. A fixed stipend is simple but confirm it satisfies your states' rules.]
5. DOCUMENTATION
Submit documentation for reimbursable costs (for example a phone or internet bill, or
a receipt for supplies) with your expense report. [State your cadence, for example
monthly.]

Reimbursement for a Small Business
A large company has a finance team to design an accountable plan and track state mandates. A small business has an owner or an office manager who needs reimbursements to be tax-free and compliant without that support. Here is what matters most at that scale, and where the risks hide.
Most templates skip the tax rule that makes reimbursements non-taxable
The expense-policy templates that rank are mostly generic fill-in-the-blank documents, and the majority treat the IRS accountable-plan rules only lightly, if at all. That is the part that actually matters: meet the three accountable-plan conditions and reimbursements are tax-free; miss them and the payments can become taxable wages subject to withholding for both the employee and the company. This policy is built around those three conditions in plain English, so a small business without a finance team can set up reimbursements that stay tax-free, rather than copying a document that looks complete but leaves the tax substance out.
State reimbursement laws catch small employers off guard, especially with remote work
Federal law does not broadly require expense reimbursement, but several states do, and this is where small employers get caught. California, Illinois, and Massachusetts, among others, require reimbursing necessary business expenses, and California requires reimbursing a reasonable percentage of a personal phone or internet bill for remote work even on an unlimited plan, and even when the employee works from home by choice. Because the obligation follows the employee's work location, hiring one remote worker in a mandate state can create a duty you did not have before. The policy and the remote-expense version here flag exactly these states so you know where to look.
A signed policy and clean records are what hold up if the IRS or an employee asks
An accountable plan is only as good as the documentation behind it. If the IRS reviews your reimbursements, or an employee disputes one, you need the signed policy, the itemized reports, and the receipts, organized and findable. Doing that on paper across a growing team is where small businesses slip. FirstHR fits this people side: capture the policy acknowledgment with e-signature at onboarding, store the signed policy and expense records in the employee profile with document management, and track who has acknowledged the current version. To be clear about scope, FirstHR is an onboarding and HR platform, not a law or accounting firm, and it does not run payroll or process reimbursements, so pair it with your payroll and accounting tools. The templates below work on their own; FirstHR is how you sign, store, and track them.
Adopt, Sign, and Store
An expense policy delivers its value when it is adopted, acknowledged, and backed by clean records. That means adapting the policy, collecting signed acknowledgments, gathering reports with receipts, and storing it all where you can produce it if the IRS or an employee asks.
Adapt the policy
Fill in your limits, deadlines, and per diem approach, add your state specifics, and have a tax or legal advisor review it.
Distribute and sign
Share the policy at onboarding and collect a signed acknowledgment with e-signature, so everyone is on notice of the rules.
Collect reports
Employees submit the expense report form with receipts by the deadline; managers approve against the policy.
Store the records
Keep the signed policy, reports, and receipts in the employee record, so your accountable plan is documented and audit-ready.
The templates above work on their own. To sign and store without paper, FirstHR captures the policy acknowledgment with e-signature at onboarding, stores the signed policy and expense records in the employee profile with document management, and tracks who has acknowledged the current version. Keep the expense policy aligned with your broader HR policies so everything points the same way. FirstHR is an onboarding and HR platform, not a law or accounting firm, and it does not run payroll or process reimbursements, so connect those separately and consult a tax or legal advisor. Applicant tracking is coming soon to FirstHR.

Frequently Asked Questions
What is an expense reimbursement policy?
An expense reimbursement policy is a written company policy that sets out which business expenses an employer will pay back to employees, and how. It defines eligible and non-reimbursable expenses, spending limits, documentation and receipt requirements, submission deadlines, and the approval and payment workflow. A well-built policy is also structured to meet IRS accountable-plan rules, which is what keeps reimbursements tax-free rather than treated as taxable wages. The policy usually pairs with an expense report form that employees use to submit their costs, and ends with an employee acknowledgment. For a small business, a clear expense reimbursement policy prevents disputes, controls costs, keeps reimbursements non-taxable, and helps meet state reimbursement laws where they apply. This is general information, not legal or tax advice.
What is an IRS accountable plan?
An accountable plan is an IRS-recognized way of reimbursing employee expenses so that the reimbursements are not treated as taxable income. To qualify, reimbursements must meet three conditions: a business connection, meaning the expense was incurred doing the job; adequate substantiation, meaning the employee documents the amount, date, place, and business purpose within a reasonable time; and return of excess, meaning any advance beyond actual substantiated expenses is returned within a reasonable time. If all three are met, reimbursements are excluded from the employee's wages and are not subject to income or employment taxes. If a plan fails any condition, it is non-accountable, and the payments become taxable wages subject to withholding. Building these conditions into your policy is the single most important thing for keeping reimbursements tax-free. This is general information, not legal or tax advice.
Are employers required to reimburse business expenses?
It depends on the state and the expense. There is no broad federal law requiring private employers to reimburse most business expenses, though federal law does prohibit letting expenses drop an employee's pay below minimum wage. Several states, however, do require reimbursement of necessary business expenses. California, Illinois, and Massachusetts have notable mandates, and others including Washington DC, Montana, Iowa, New Hampshire, North Dakota, and South Dakota have requirements as well. California is especially broad, covering mileage, phone, internet, and home-office costs. Because the obligation follows the employee's work location, an employer with remote workers may be subject to several states' rules at once. Confirm the requirements for every state where your employees work. This is general information, not legal or tax advice.
What expenses should be reimbursed?
Typical reimbursable business expenses include travel such as economy airfare, standard lodging, and rental cars; meals while traveling, either by receipt or per diem; business mileage in a personal vehicle; approved office supplies, tools, and equipment; business phone and internet for remote workers; and approved conference, training, and professional fees. Commonly non-reimbursable items include personal entertainment, commuting between home and the regular workplace, traffic and parking fines, alcohol unless pre-approved as client entertainment, spouse or companion travel, unauthorized upgrades, and personal items. The exact list is a business decision, but it should be written down clearly so employees know what qualifies before they spend. State law may require reimbursing certain categories, especially for remote work. This is general information, not legal or tax advice.
What is the IRS mileage rate, and do I have to use it?
The IRS standard mileage rate is an optional per-mile rate employers can use to reimburse business use of a personal vehicle, set to cover fuel, maintenance, depreciation, insurance, and registration. The IRS updates it each year, so you should confirm the current rate rather than relying on a prior year's figure. Private employers are not required to use the IRS rate, but it is the common, defensible benchmark: reimbursing at or below it under an accountable plan keeps the reimbursement tax-free without tracking actual vehicle costs. Some states factor in as well; in California, for example, paying the IRS rate generally satisfies the employer's vehicle-expense obligation, though an employee can show actual costs were higher. Reference the live IRS rate in your policy rather than hard-coding a number. This is general information, not legal or tax advice.
What is a per diem, and should a small business use one?
A per diem is a fixed daily allowance for travel costs, typically meals and incidental expenses and sometimes lodging, paid instead of reimbursing itemized receipts. Many employers use the federal GSA per diem rates as a benchmark, because reimbursing at or below the federal rate under an accountable plan is treated as substantiated without collecting every meal receipt. A per diem can simplify travel reimbursement for a small business and reduce paperwork, though it can over- or under-pay on a given trip. If you use one, the first and last travel days are typically paid at a reduced rate, and you should confirm the current federal rate for the location. Whether to use a per diem or receipts is a business choice; both can work under an accountable plan. This is general information, not legal or tax advice.
How long do employees have to submit expenses?
The deadline is set by your policy, but it should fall within what the IRS considers a reasonable time to keep the plan accountable. A common approach uses a safe-harbor guideline: employees submit expenses within 60 days of incurring them, and return any excess advance within 120 days. Many small businesses set a submission deadline of 30 or 60 days to keep records current and reimbursements timely. Setting a clear deadline matters for two reasons: it keeps your accountable plan valid, and it prevents stale expenses from piling up months later. State law can also impose timing; Illinois, for example, generally requires submission within 30 days. State your deadline plainly in the policy and apply it consistently. This is general information, not legal or tax advice.
Is expense reimbursement taxable to the employee?
Not if it is paid under an accountable plan. When reimbursements meet the three accountable-plan conditions, business connection, substantiation, and return of excess, they are excluded from the employee's gross income, are not reported as wages on the W-2, and are not subject to income or employment taxes. If the plan is non-accountable, meaning it fails one or more of those conditions, the payments are treated as taxable wages and are subject to income tax and FICA withholding for the employee and payroll taxes for the employer. This is exactly why the accountable-plan structure matters so much, and why a policy that documents business purpose, requires substantiation, and requires return of excess is worth getting right. This is general information, not legal or tax advice.
