Expense Claims: A Practical Guide for Employees and Freelancers

If you've ever spent your own money on something for work and then waited weeks for your employer to reimburse you, you already understand the problem this guide solves. The mechanics of expense claims look simple — keep a receipt, fill in a form, get your money back — but the practical reality involves a maze of company policies, tax rules, mileage rate thresholds, VAT recovery procedures and the boring but unforgiving demands of an accounts team that needs every line to add up before they cut a cheque. This article walks through every part of the process, from what counts as a claimable expense in the first place to the right way to handle mileage in 2026 to what your accounts department actually wants to see on a printed claim form.

What is an expense claim, and who needs one?

An expense claim — also called an expense reimbursement form, expense report or business expense claim — is a structured document submitted by someone who has paid for a legitimate business expense out of their own pocket and wants the money back. The claimant is usually an employee, but can also be a contractor, a freelancer billing time and materials, a director of a small limited company reimbursing themselves, or a volunteer for a charity claiming back tolls and parking. The recipient is whoever holds the budget — usually the company's accounts team, the finance department of a school, the treasurer of a non-profit, or in the case of self-employed sole traders, your own future self filing a Self Assessment tax return where the expenses go on the deductions page.

The form exists for two reasons. The first is operational: the accounts team needs a clear, structured record of what was bought, when, by whom, why and for how much, so they can match it against budget lines, project codes and the receipts you've attached. The second is regulatory: tax authorities require evidence that any expense being deducted from a company's taxable profits or being reimbursed tax-free to an employee is actually a legitimate business cost. A loose pile of crumpled receipts on a manager's desk doesn't satisfy either requirement. A properly structured claim form does.

What counts as a claimable business expense?

The general rule applied by both UK HMRC and US IRS is that an expense is claimable if it was incurred wholly and exclusively (UK) or ordinary and necessary (US) for business purposes. The wording differs, the intent is the same: would you have spent this money if you weren't doing your job? If yes, it's not a business expense — it's a personal one. If no, it usually qualifies. Common categories that almost always qualify include travel to a temporary work location (not your daily commute to a permanent office, which is explicitly excluded in both jurisdictions), accommodation when staying away from home for work, meals while travelling for business, software subscriptions used for work, training courses and conference fees directly related to your role, office supplies you bought for the company, equipment up to the small-purchase threshold your company allows, parking and tolls for business journeys, and mileage in your personal vehicle when used for business.

Common categories that get rejected include the daily commute (your home-to-office journey is private travel even if you take a client phone call on the way), clothes (unless they're a specific uniform with the company logo or required PPE), entertainment that crosses the line into personal benefit, gifts above the per-recipient limit set by your local tax authority, alcohol with meals in countries that disallow it, and anything with a personal-use dimension that you can't cleanly separate from the business use. When in doubt, ask your accounts team or your accountant before you submit — it's much faster to clarify upfront than to argue about it after the claim is rejected.

Mileage: the most misunderstood part of any claim

Mileage reimbursement is the single most error-prone area of expense claims, partly because the rates change occasionally and partly because the rules around them are surprisingly intricate. The basic concept is simple: instead of tracking actual fuel, insurance, depreciation, servicing, MOT, tyres, road tax and finance costs separately for the business use of your personal vehicle, you multiply your business miles by a flat per-mile rate that's meant to cover all of those things in one number. Both the US IRS and the UK HMRC publish standard rates that employers can use as a tax-free reimbursement benchmark.

For 2026, the IRS standard business mileage rate is 72.5 cents per mile — up 2.5 cents from the 70¢ rate that applied in 2025, and the highest rate in IRS history. The change took effect on January 1, 2026 and applies to all business use of a personal car, van, pickup or panel truck regardless of whether the vehicle runs on petrol, diesel, hybrid power or pure electricity. A US employer can reimburse an employee at 72.5¢/mile and that payment is tax-free for both parties. Reimbursement above 72.5¢/mile becomes taxable income to the employee. There's no per-year mileage threshold in the US — the same rate applies to the first business mile and the ten-thousandth.

The UK system works very differently. HMRC publishes Approved Mileage Allowance Payments (AMAP rates) that have been frozen since April 2011 at 45p per mile for the first 10,000 business miles in a personal car or van during a tax year, dropping to 25p per mile for any additional miles in the same tax year. The 10,000-mile threshold resets each tax year on 6 April, and crucially, it follows the person and not the employer — if you change jobs mid-tax-year, your cumulative miles for AMAP purposes carry across. Motorcycles get a flat 24p/mile, bicycles 20p/mile, and there's an additional 5p/mile passenger allowance if you carry a business colleague in your own car. EVs use the same 45p/25p car rate as petrol — there is no separate AMAP rate for electric vehicles, which has become a point of controversy as EV running costs are very different from petrol. The Expense Claim Generator handles all of this automatically when you select the UK preset: enter your miles, and it splits the calculation across the 10,000-mile threshold for you.

Per diems vs itemised meals — when each makes sense

If you travel for work, you'll eventually run into the choice between claiming meals as itemised receipts and claiming a per diem. A per diem is a flat daily allowance — typically covering breakfast, lunch, dinner and incidentals like tips and laundry — that the employer pays for each day of business travel regardless of what you actually spent. The advantage for the employee is that you don't need to keep restaurant receipts; the advantage for the employer is administrative simplicity and cost predictability. In the US, the GSA publishes per diem rates by city that federal employees use and that many private employers adopt as their internal rate. In the UK, HMRC publishes "scale rate" allowances for subsistence that employers can pay tax-free without receipts, with rates depending on the length of the working day. Most other countries have similar schemes.

Itemised meal receipts make sense when actual meal costs significantly exceed the per diem (you're entertaining a client at an expensive restaurant, or you're in a city where the local per diem is unrealistically low) or when your company doesn't offer per diems at all. Per diems make sense when you'd rather not save and submit receipts, when the per diem is generous relative to what you'll actually spend, or when company policy mandates it. The Expense Claim Generator supports both — add itemised meal lines in the Itemised expenses section and per diem rows in the Per diems section, and the totals are kept separate so the accounts team can see at a glance which method applies to each day.

VAT, sales tax and the gross-vs-net question

If your company is VAT-registered (UK and EU) or sales-tax-registered (US), the accounts team needs to know how much of each expense was tax and how much was the underlying cost — because the company can usually recover the tax portion from the government. This is why the itemised expenses table in the generator has separate Net, Tax % and Gross columns. Enter the net (pre-tax) amount and the tax percentage that applies, and the gross figure is calculated automatically. The totals block at the bottom shows the total net, total tax, and total gross separately.

If you don't need to track tax — most freelancers and small claims fall into this bucket — leave the tax percentage at 0 and the net and gross figures will be identical. Mileage and per diems typically aren't VAT-rated (they're treated as flat-rate compensation, not taxable supplies of goods or services), which is why those tables don't have a tax field. Always check with your local accounts team if you're not sure — VAT recovery rules are notoriously fiddly and vary by jurisdiction.

Receipts: keep them, attach them, reference them

The expense claim form itself is the cover sheet. The receipts are the evidence. Most companies — and definitely most tax authorities — require the original receipt for any expense above a small de minimis threshold (typically $25/£25 in cash, no minimum for credit card transactions where the statement provides a backup record). Modern practice is to photograph or scan each receipt the moment you get it, store the digital image somewhere durable, and reference it by an ID or row number on the claim form so the accounts team can match the line item back to the source document.

A clean approach: when you click Add row in the generator, the description field is a good place to write a short note like "Lunch with client — receipt #14" so a reviewer can find the matching receipt in your attached PDF or shared folder. If you're submitting the claim by email, attach the receipts as a single combined PDF in the same email as the printed claim form. If you're using a corporate expense system, upload the receipts to that system and put the system's internal receipt ID in the description field of the claim. Without receipts, the safest assumption is that the claim will be rejected — even small amounts.

Submitting the claim

Once you've filled in every section, reviewed the totals and added any notes for the accounts team, the final step is to produce the printable copy. Click Print / Save as PDF in the toolbar and the browser print dialog appears. Crucially, the print stylesheet baked into the Expense Claim Generator hides the editor toolbar, the navigation header, the ad placements, the rating widget and all the marketing content below the form — what you'll see in the print preview is just the claim form itself, clean and professional, with the company branding stripped out so it looks like a proper business document. Choose "Save as PDF" (or "Microsoft Print to PDF" on Windows) instead of a physical printer and you have a file you can email to your accounts team or upload to your expense system.

Sign the form before submitting. If you're submitting digitally, you can either print it, sign with a pen, scan it back, or use a PDF signing tool to apply a digital signature directly to the PDF. The signature block at the bottom of the form has space for both the claimant signature and the approving manager signature — the manager will fill in their side after they've reviewed and approved the claim, before passing it to accounts for payment. Some companies skip the manager-signature step in favour of an electronic approval workflow, in which case you can leave that side blank.

Common mistakes that get claims rejected

The fastest ways to get an expense claim sent back unpaid: claiming your daily commute as business mileage (it's not, in either the UK or US, no matter how many phone calls you take in the car), forgetting to attach receipts for items above the de minimis threshold, mixing personal and business items on a single line ("groceries — $84" gets rejected; "client meeting refreshments — $24" plus a separate personal line doesn't), using last year's mileage rate (the IRS rate changed from 70¢ to 72.5¢ on 1 January 2026 — make sure you're using the right one for the date the trip happened), claiming alcohol in jurisdictions or company policies that disallow it, claiming amounts that don't match the attached receipts, leaving the description field blank or unhelpfully vague ("lunch" tells the accounts team nothing — "lunch with John Smith of Acme Corp re Q1 contract negotiation" tells them everything), and forgetting to sign the form. None of these mistakes is dramatic individually but each one creates back-and-forth with accounts that delays your reimbursement. The Expense Claim Generator can't stop you making most of these errors but the structure of the form makes it harder to forget the basics.
