How to Claim Expenses: A Practical Guide
An expense claim form is how an employee gets reimbursed for money they spent on the company’s behalf, client dinners, mileage, hotel stays, materials bought out of pocket. It’s one of the most-used finance documents in any business, and one of the most abused when the rules are loose. A clear form with clear rules keeps claims fast, fair, and defensible.
This guide covers staff expense claims: out-of-pocket spending reimbursed after the fact. Company cards and per-diem travel allowances are different systems with different controls; the claim form is for money the employee actually spent and can evidence.
Note: tax treatment of reimbursed expenses, mileage rates, and record-keeping requirements vary by jurisdiction. Check your local regulations and set your company’s expense policy in writing before claims start arriving.
When to Use This
Employees submit a claim as soon as possible after the spending, ideally within the same month, and your policy should set a hard deadline (30 days is common; 90 days is generous). Old claims are hard to verify, receipts fade, and memories of “that dinner in March” get creative by June. Claims older than the deadline should be rejected, politely but firmly, or the deadline means nothing.
Use one claim form per trip or per month, depending on volume. A salesperson submitting weekly claims should batch each week on one form; an office worker claiming a single taxi fare submits one form for that item. What doesn’t work is a shoebox of receipts arriving at year-end with a note saying “sort it out.”
Claims are for legitimate business spending only, and the form should say so. The test is simple: was this spent because of the job, and would a reasonable manager approve it in advance? A $65 client lunch, yes. A $180 dinner for one with no client present, that needs a very good explanation.
How to Fill It Out
Section 1: Claimant details. Full name, department, employee ID if you use them, and the claim period (e.g. “1–7 April 2026” or “April 2026”). Include the bank account details for reimbursement if they’re not already on file, and never change bank details on the basis of a claim form alone; verify changes separately.
Section 2: Expense lines. One line per expense: date, description, category (Travel, Accommodation, Meals, Mileage, Supplies, Other), and amount. Be specific: “Dinner with client (Brightline Services, Daniel R.), 14 April” not “food.” For mileage, record the journey (from/to), the distance, and the rate applied, “Office to client site, 42 km at $0.45/km = $18.90.”
Section 3: Receipts. Every line needs a receipt attached or referenced, in the same order as the lines on the form. Original itemised receipts, not card slips that show only a total, a $120 card slip from a restaurant proves nothing about what was business and what wasn’t. Where receipts are genuinely unavailable, the claimant adds a signed note with the details, and the approver decides whether to accept it.
Section 4: Business purpose. For each line, or at minimum for meals, entertainment, and travel, state the business reason. “Client meeting,” “site visit,” “team working dinner during system rollout.” This is the section approvers actually read, and it’s what justifies the spend to anyone reviewing later, including auditors.
Section 5: Totals. Subtotal by category and a grand total, calculated by the claimant. The approver rechecks the arithmetic, claim forms with wrong totals are surprisingly common, and catching a $40 addition error is part of the approver’s job.
Section 6: Declarations and signatures. The claimant signs to declare the expenses are genuine, business-related, and not claimed elsewhere. The approver signs to confirm they’ve reviewed the receipts and the claim complies with policy. Include the approval date. Unsigned claims don’t get paid.
Common Mistakes
1. Missing or vague receipts. A claim with three card slips and no itemisation can’t be verified. Set the standard clearly: itemised receipts for everything over a small threshold (say $25), and no receipt means no reimbursement unless the approver explicitly accepts the explanation.
2. Personal spending mixed in. The hotel minibar, the extended-stay upgrade, the family member’s meal added to the bill. Claimants should strip personal items off before submitting, approvers shouldn’t have to play detective. A pattern of “accidental” personal items is a conversation, not a coincidence.
3. Approvers who don’t check. The manager signs every claim in the pile without looking, and the control collapses. Approvers must actually review: receipts present, amounts match, business purpose stated, policy limits respected. If managers won’t do it, move approval to finance.
4. No policy limits. Without written caps, hotel per night, meal per head, mileage rate, every claim becomes a negotiation and every rejection feels personal. Publish the limits, put them on the form or beside it, and apply them evenly. “Meals up to $50 per person per day” ends arguments before they start.
Who Needs to Sign Off
The claimant’s line manager approves first, confirming the spending was legitimate and necessary. Finance checks the arithmetic, the receipts, the policy limits, and the coding, then processes payment. Claims above a threshold (e.g. $1,000) or claims by managers themselves go to the next level up, nobody approves their own expenses, and directors’ claims are approved by a fellow director or the owner.
How Often to Review and Update
Process claims on a fixed schedule, weekly or fortnightly, so employees aren’t waiting a month for reimbursement; slow payment breeds sloppy claiming. Review the expense policy and the form’s limits annually against actual spending: if everyone is breaching the hotel cap, the cap is wrong, not the travellers. Audit a sample of claims quarterly for receipt quality and policy compliance, and publish the common issues so the whole company learns at once.
