Expense Report Template: How to Fill Out and Submit One

Quick answer: An expense report template is a standard form for claiming back business costs you paid yourself. List each expense with its date, merchant, category, business purpose and amount, attach receipts, subtract any advance, sign it and submit it to your approver within your company's deadline.

Expense reports are one of those tasks nobody enjoys and everybody has to get right. A missing receipt delays reimbursement, a vague business purpose gets the claim rejected, and in the US a sloppy process can turn tax-free reimbursements into taxable wages. This guide walks through what an expense report is, which fields to include, how to fill one out step by step with a worked example, the US accountable plan rules employers rely on, and the mistakes that most often get claims sent back.

What is an expense report?

An expense report is an internal document an employee submits to claim reimbursement for business costs paid with personal money or to account for costs charged to a company card or paid from an advance. It is the bridge between "I paid for this hotel" and "the company has recorded the cost, checked it against policy and paid me back."

It is different from an invoice. An invoice goes from a seller to a customer. An expense report goes from an employee to an employer. If you are a freelancer passing costs on to a client, you do not file an expense report; you add the costs to your invoice. Our guide to billing reimbursable expenses on an invoice covers that case.

What to include in an expense report template

A good expense report template has three parts: a header that identifies the claim, a table of expense lines, and a summary that settles any advance and records approvals.

Header fields

• Employee name, employee ID and department or cost center.
• Report number or reference.
• Reporting period or trip dates.
• Purpose of the trip or project, for example "Client workshop, Chicago".
• Currency of reimbursement.

Expense line columns

Column	What to enter	Why it matters
Date	Date on the receipt	Shows the expense falls within the claim period
Merchant or description	"Marriott Downtown, 2 nights"	Lets the approver match the line to the receipt
Category	Airfare, lodging, meals, ground transport, mileage, supplies	Maps the cost to the right ledger account
Business purpose	"Dinner with client re: Q1 project scope"	Required for tax substantiation and policy checks
Payment method	Personal card, cash, company card	Company card items are accounted for but not reimbursed
Amount	Total paid, including tax and tip	The figure being claimed
Receipt reference	Receipt number or attachment name	Links evidence to each line

Summary and approval

• Total expenses.
• Less company card charges (if they are listed for accounting only).
• Less cash advance received.
• Net amount due to the employee, or due back to the company.
• Employee signature and date, confirming the expenses are accurate and business related.
• Approver name, signature and date.

How to fill out an expense report, step by step

1. Gather your evidence. Collect receipts, booking confirmations and card statements for the period. Photograph paper receipts the day you get them.
2. Check the policy. Look up per-night lodging caps, meal limits, the mileage rate and which expenses are not reimbursable (for example, alcohol or upgrades).
3. Enter one line per expense. Use the receipt date and the full amount paid. Do not combine several meals into one line unless your policy allows a daily total.
4. Write a real business purpose. "Meals" is not a purpose. "Lunch with Dana Ruiz, Acme Corp, to review proposal" is.
5. Add mileage separately. Record the date, start and end points, purpose and miles, then multiply by the approved rate. A separate mileage log template makes this much easier.
6. Subtract advances. If you received cash up front, deduct it to get the net amount owed.
7. Attach receipts and sign. Number each receipt to match its line and sign the declaration.
8. Submit before the deadline. Send it to your manager or finance team and keep a copy.

Worked example: a filled expense report

The figures below are illustrative. An employee travels to a two-day client workshop in August 2026 and received a $500.00 cash advance before the trip.

Date	Description	Category	Business purpose	Amount
Aug 10	Return flight, Boston to Chicago	Airfare	Travel to Acme client workshop	$412.60
Aug 10-12	Hotel, 2 nights x $189.00	Lodging	Accommodation for workshop	$378.00
Aug 11	Dinner with Acme project lead	Meals	Review workshop outcomes and next steps	$64.25
Aug 11	Taxi, hotel to Acme office and back	Ground transport	Travel to client site	$38.40
Aug 12	Personal car, home to airport and back, 46 miles x $0.76	Mileage	Airport transfer for client trip	$34.96

Calculation:

• Lodging: 2 x $189.00 = $378.00.
• Mileage: 46 x $0.76 = $34.96 (using the IRS business rate for July 1 to December 31, 2026; your employer's rate may differ).
• Total expenses: $412.60 + $378.00 + $64.25 + $38.40 + $34.96 = $928.21.
• Less cash advance: $928.21 - $500.00 = $428.21 due to the employee.

If the total had been lower than the advance, say $430.00, the employee would owe the company $500.00 - $430.00 = $70.00, and under a US accountable plan that excess must be returned within a reasonable period.

US rules: accountable plans and substantiation

In the US, the way an employer reimburses expenses affects whether the payment is taxable to the employee. Under an accountable plan, reimbursements are generally not wages and are not reported as income. To qualify, the plan must meet three requirements described in IRS Publication 463:

1. Business connection. The expenses must be deductible business expenses incurred while performing services as an employee.
2. Adequate accounting. The employee must substantiate the expenses to the employer within a reasonable period of time.
3. Return of excess. The employee must return any amount above the substantiated expenses within a reasonable period.

Publication 463 gives examples of timing it treats as reasonable: receiving an advance within 30 days of the expense, accounting for expenses within 60 days after they were paid or incurred, and returning any excess within 120 days. Employers can instead give employees a periodic statement, at least quarterly, of outstanding amounts and ask them to account for or return them within 120 days of the statement.

If a plan does not meet these rules, it is a nonaccountable plan, and the payments are treated as wages: they are reported on Form W-2 and subject to withholding. That is a good reason for employers to insist on complete, timely reports.

Substantiation means recording the amount, time, place and business purpose of each expense, ideally at or near the time it happens. Publication 463 says documentary evidence such as a receipt is generally not needed for expenses under $75, except lodging. Employer policies are often stricter and require a receipt for every item. The rules change from time to time, so check the current publication before setting policy.

How approvers review an expense report template

Knowing what the reviewer checks helps you get paid on the first submission. Most approvers and finance teams run through the same questions:

• Does every line have evidence? They match each amount to a receipt or booking confirmation and check that the dates fall inside the claim period.
• Is it within policy? Lodging and meals are compared against caps, and items such as alcohol, upgrades or personal travel are removed.
• Is the purpose clear? A reviewer who cannot tell why a cost was business related will send the line back.
• Is the arithmetic right? Totals, mileage multiplication and the advance deduction are rechecked.
• Is anything claimed twice? Duplicate receipts, or company card charges listed as out-of-pocket, are common errors.

Building these checks into your own expense report template, for example with a "receipt attached" column and formula-driven totals, catches most problems before you hit submit.

Expense report vs invoice vs petty cash

Document	Who issues it	To whom	Purpose
Expense report	Employee	Employer	Claim back or account for business costs
Invoice	Seller or freelancer	Customer or client	Request payment for goods or services, including rebilled costs
Petty cash voucher	Petty cash custodian	Internal records	Record small cash payouts from the office float

For small office purchases paid from a cash box, a petty cash log is usually simpler than a full report.

Expense report checklist

• Header complete: name, department, period, trip purpose, currency.
• One line per expense with date, merchant, category and amount.
• A specific business purpose on every line.
• Receipts attached and numbered to match lines (lodging always).
• Mileage recorded with date, route, purpose, miles and rate.
• Company card items marked so they are not reimbursed twice.
• Advances subtracted and net amount calculated.
• Totals double-checked.
• Employee signature and approver signature.
• Submitted before the policy deadline, with a copy kept.

Common mistakes

• Vague purposes. "Travel" or "lunch" does not explain the business reason. Name the client, project or meeting.
• Claiming company card charges as reimbursable. They are already paid by the company. List them only if your policy asks you to account for them.
• Forgetting the advance. Leaving out a cash advance overstates what you are owed and gets the report rejected.
• Missing receipts. Photograph receipts immediately. If one is lost, attach a signed missing-receipt statement if your policy allows it.
• Wrong mileage rate. In 2026 the IRS business rate changed mid-year, from 72.5 cents to 76 cents per mile on July 1. Use the rate that applies to the trip date, or your employer's own rate.
• Submitting months late. Late reports can miss accountable plan timing and become taxable, as well as distort the company's monthly accounts.
• Personal items mixed in. Minibar charges, family meals or personal side trips should be removed before you submit.

Tools and templates

A spreadsheet works for a handful of claims a month: one tab per report, a line table with formulas for totals, and a summary block for the advance. Many companies use expense software that reads receipts automatically. Whichever you use, the fields above stay the same.

If you are self-employed, you do not reimburse yourself through an expense report, but you still need records for deductions. Our guides to tracking business expenses and self-employed tax deductions explain what to keep. Understanding which costs count as operating expenses also helps you categorize lines correctly.

When a client has agreed to cover costs, bill them on an invoice instead. The invoice generator lets you add each cost as a line item, apply one tax rate where needed and note "receipts attached" in the terms before downloading a PDF. It does not produce expense reports, so keep a dedicated expense report template for employee claims. If you need to work out the tax portion of a receipt total, the sales tax calculator can help.
