An expense account is money a business sets aside for employees to spend on work-related costs, then get reimbursed

An expense account is a pool of money your employer gives you to pay for things the business needs — travel, meals with clients, office supplies, conference fees, or equipment. You spend your own money or a company card first, then submit receipts to your accounting department and get paid back. Some companies give you a set monthly budget; others reimburse whatever you actually spend, as long as it's work-related.

The money comes from your employer's operating budget, not your salary. It exists because certain jobs require spending money on behalf of the company — a sales rep traveling to meet clients, a manager buying lunch for a team meeting, a consultant purchasing software licenses. Rather than have employees absorb these costs, the business covers them through reimbursement.

Expense accounts are different from a business credit card or a company debit card, though those are often used to fund them. With a credit card, the company pays the bill directly. With an expense account, you typically pay first and then request reimbursement, though some systems let you charge to the account and skip the reimbursement step.

Key Takeaways

  • An expense account reimburses employees for money they spend on work-related purchases, and the business tracks these costs separately from salary.
  • Common expense account categories include travel, meals, client entertainment, office supplies, and professional development.
  • You will need to keep receipts and submit them with a reimbursement request, usually through accounting software or a form your employer provides.
  • Expense accounts have limits set by your employer and by tax law — the IRS does not allow reimbursement for personal expenses, even if your boss says yes.
  • If your employer does not reimburse you within a reasonable time, you may be able to deduct unreimbursed work expenses on your tax return, depending on your job type.

How expense account reimbursement actually works

The process usually follows the same steps. You spend money on something work-related — a flight, a meal with a client, a software subscription. You keep the receipt. You log into your company's expense management system (or fill out a paper form) and enter the amount, the date, the category, and what it was for. You attach the receipt as proof. Your manager reviews it and approves or denies it. Once approved, accounting processes the reimbursement and deposits it into your bank account or adds it to your next paycheck.

The timeline varies by company. Some reimburse within a week; others take two to four weeks. Your employee handbook or finance department should tell you the expected wait time and whether reimbursement goes to your personal bank account or your paycheck.

Some employers use a corporate credit card instead, where you charge the expense to the card and the company pays the bill directly. You still submit receipts and categorize the expense, but you do not handle the money yourself. This method is faster and leaves less room for error, but requires the company to trust you with a card.

What counts as a reimbursable business expense

The IRS has strict rules about what businesses can deduct as a business expense, and your employer will follow those rules to avoid tax trouble. Reimbursable expenses generally fall into these categories: travel (flights, hotels, rental cars, parking, tolls), meals and entertainment (client dinners, team lunches, conference meals), office supplies and equipment, professional development (courses, certifications, conferences), client gifts (within limits), and vehicle mileage if you use your own car for work.

What does not count: personal grooming, gym memberships, commuting costs to your regular workplace, alcohol you drink alone, entertainment that is not business-related, and anything that looks like personal spending. The rule is simple — would the business have spent this money if you did not work there? If the answer is no, it is not reimbursable.

Your employer may have stricter rules than the IRS. A company might not reimburse meals over $15, or might require pre-approval for any expense over $500. Check your employee handbook or ask your manager what your company's policy is.

Keeping records and submitting receipts

You must keep receipts for every expense you want reimbursed. A credit card statement alone is not enough — you need the actual receipt showing what you bought. For meals, the receipt should show the date, the restaurant name, the total amount, and ideally a list of who attended and what the meal was for (though some companies only require this for meals over a certain amount).

Save receipts as you go. Do not wait until the end of the month to dig through your email and credit card statements. Most companies have a deadline for submitting expenses — often 30 to 60 days after you incur them. If you miss the deadline, your employer may refuse to reimburse you, even if the expense was legitimate.

When you submit, be clear about what each expense was for. "Client dinner" is not as useful as "Client dinner with Jane Smith from Acme Corp to discuss Q2 contract." The more detail you provide, the faster your manager can approve it and the less likely accounting will send it back asking for clarification.

Limits and caps on expense accounts

Most employers set a monthly or annual cap on how much you can spend through an expense account. A sales rep might have a $2,000 monthly travel budget; an office worker might have a $100 monthly supplies budget. These limits vary widely by job, industry, and company size. Your offer letter or employee handbook should state your limit.

Some companies use a tiered system: expenses under $25 do not need a receipt, expenses between $25 and $500 need a receipt and manager approval, expenses over $500 need a receipt, manager approval, and finance director sign-off. Again, your company's policy is what matters.

If you exceed your limit, your employer can deny the reimbursement or require you to pay the overage yourself. Going over budget repeatedly can also affect your performance review or your ability to use the account in the future.

What to do if reimbursement is delayed or denied

If your employer does not reimburse you within the promised timeframe, follow up with accounting in writing — email is fine. State the date you submitted the expense, the amount, and the date you expected reimbursement. Keep a copy for your records.

If your employer denies a reimbursement, ask why in writing. The reason might be that you missed the deadline, the expense does not fit company policy, or the receipt was unclear. If you believe the denial was wrong, you can appeal to your manager or the finance department, but your employer has the final say.

If your employer consistently fails to reimburse you or refuses to reimburse legitimate business expenses, this may be a wage and hour violation depending on your state. Some states require employers to reimburse employees for necessary work expenses. You can file a complaint with your state's labor department or consult an employment lawyer.

Expense accounts and your taxes

Money your employer reimburses you for business expenses is not taxable income — it does not count toward your gross income and is not subject to income tax or payroll tax. This is different from a bonus or a raise, which are taxable.

If your employer does not reimburse you for a work expense you had to pay out of pocket, you may be able to deduct it on your tax return — but only if you are self-employed or if you are an employee in certain professions (military reservists, performing artists, and a few others). Most employees cannot deduct unreimbursed work expenses. Check with a tax professional about your specific situation.

Frequently Asked Questions

Can my employer take money back from my paycheck if I submit a false expense?

Yes, if you submit a receipt for something you did not actually buy or that was not work-related, your employer can deny reimbursement and may discipline you. In some cases, if the false claim is large enough, they can pursue legal action. Do not submit expenses you cannot prove with a receipt.

What if I lose a receipt?

Most companies will not reimburse an expense without a receipt, even if you remember buying it. Some allow a written statement from a witness (like a coworker who attended a meal with you) or a credit card statement as backup, but this varies by employer. Ask your accounting department what they accept before you submit.

Do I have to use my personal money, or can I use a company card?

That depends on your employer. Some companies give you a corporate card and expect you to use it; others let you choose. If your company offers a card, using it is usually faster because the company pays the bill directly and you do not have to wait for reimbursement. Ask your manager which method your company prefers.

What happens to my expense account if I leave the job?

Any expenses you submitted before your last day should still be reimbursed, as long as you submitted them within your company's deadline. Expenses you incur after you leave are not your employer's responsibility. Make sure to submit all pending expenses before you go.

Can I use my expense account for personal things if I pay it back later?

No. An expense account is only for business expenses. Using it for personal purchases, even if you intend to repay it, is misuse of company funds and can result in discipline or termination. Keep personal and business spending separate.
