How should a business handle and document travel expense reimbursements paid to non-employees?

Which travelers does this cover, and which differences change the handling?

The route applies only to a traveler who is not your employee. The IRS page defining an independent contractor gives the general rule: a person is one if whoever receives the services has the right to control or direct only the result of the work, not what will be done and how. The same page adds that where an employer-employee relationship exists, whatever it is called, the person is not an independent contractor. If the traveler is in substance your employee, use your employee reimbursement process; the IRS instructions for Forms 1099-MISC and 1099-NEC say not to use Form 1099-NEC for employee business expense reimbursements.

Among non-employees, what changes the handling is whether a fee is paid for services, not the person's title, except that the 1099 instructions exclude expense reimbursements paid to volunteers of nonprofit organizations:

What must be agreed before the trip?

A non-employee has no expense policy or payroll relationship to fall back on, so the written arrangement (engagement letter, board-approved policy or invitation) is what makes the later payment supportable; an invoice sent after the trip can only apply it. Settle these points before any cost is incurred:

• Costs covered. List the costs you will repay (airfare or rail, lodging, meals, local transport), any class or rate limits, and what you will not repay.
• Evidence. Require an itemized statement giving each expense's amount, date, place and business purpose, built from a record the traveler keeps during the trip, with receipts attached and meals shown separately.
• Deadline. Set a date for the statement, for example 30 days after the trip ends. Neither Publication 463 nor the 1099 instructions set a deadline for a non-employee's statement or settlement, so your date governs; Publication 463's reimbursement time limits are for employees.
• Approver. Name the person, other than the traveler, who checks the statement against the arrangement before anything is paid.
• Billing route. Say whether travel is claimed on its own statement or itemized on the fee invoice with the statement and receipts, never folded into the fee.
• Advance. State any advance, its settlement date, the duty to return what is unspent and whether you may recover it from a later fee.
• Payee record and payment details. State that no money moves, advance included, until the payee record is on file and the payment details are confirmed.
• Originals. Say who keeps original receipts and what copies the business receives.

What must the traveler supply for each kind of cost, and who keeps it?

IRS Publication 463 (2025) says a self-employed person adequately accounts to a client by reporting actual expenses, and treats documentary evidence as ordinarily adequate if it shows the amount, date, place and essential character of the expense. Ask for what Publication 463 describes for each cost:

Publication 463 generally requires documentary evidence such as receipts, canceled checks or bills. Among its exceptions, Publication 463 (2025), for 2025 returns, excuses documentary evidence for an expense other than lodging under $75 and for a transportation expense without a readily available receipt; recheck the $75 figure in the 2026 edition when it is issued. Publication 463 says to record the elements of an expense at or near the time of the expense, and that an expense account statement given to a client can count as a timely kept record if the traveler copies it from an account book, diary, log, statement of expense, trip sheets or similar record. Have the traveler keep such a record during the trip and build the statement from it; a prompt deadline alone does not make the statement a timely kept record.

Publication 463 tells a contractor to keep adequate records whether or not it accounts to the client, so let a contractor keep its originals and send you complete copies. Publication 463 requires the client to keep records documenting each element of non-entertainment meal expenses a contractor adequately accounts for; keep complete copies of every accounting, never just a summary claim, because they show the reimbursement was accounted for, which decides the reporting treatment.

Should you repay actual costs, pay a flat amount or advance the money?

The choice decides what you collect and how the payment counts toward the payee:

What decides whether the reimbursement becomes reportable to the payee?

Whether the traveler accounted to you. Publication 463 says that if a contractor adequately accounts to you for reimbursed amounts, you do not have to report the amounts on an information return, and that a contractor who does not account to the client must include any reimbursements or allowances in income. The IRS instructions for Forms 1099-MISC and 1099-NEC, revised 12/2026, list among payments to report as nonemployee compensation a fee paid to a nonemployee or a travel reimbursement for which the nonemployee did not account to the payer, if the fee and reimbursement total at least $2,000. The same instructions apply the $2,000 threshold for tax years beginning after 2025, with inflation adjustment possible from calendar year 2027, and direct that their December 2026 revision be used to file 2026 information. Publication 463 (2025) still shows the older $600 figure and Form 1099-MISC; for 2026 payments, follow the December 2026 1099 instructions.

The same 1099 instructions exclude expense reimbursements paid to volunteers of nonprofit organizations from box 1a and treat nonprofit organizations as engaged in a trade or business and subject to these reporting requirements. The general four-part test for nonemployee compensation in those instructions is covered in the linked question on 1099s.

Your support for leaving a reimbursement out of the payee's total is the accounting itself (the statement built from the trip record, and the receipts), the approver's sign-off and a payment record showing the reimbursement paid apart from the fee.

What payee record should be on file before any money moves?

The record has two parts:

• Status. Record your decision, under the control test above, that the traveler is not your employee, and record whether the payee is an individual, partnership, estate or corporation, as its W-9 shows, because the 1099 instructions' general reporting test turns on both.
• Tax identification. The W-9 requester instructions say Form W-9 is used by persons required to file information returns to get the payee's correct name and TIN. The 1099 instructions make payees who have not furnished TINs subject to backup withholding on payments required to be reported in box 1a, with the same $2,000 threshold.

Neither the W-9 requester instructions nor the 1099 instructions set a date for obtaining a W-9, but box 1a payments to a payee who has not furnished a TIN are subject to backup withholding, so holding payment until you have the W-9 is both your control and your last leverage. Apply it this way:

• Anyone you pay a fee, and anyone who will receive an advance or a flat amount, returns a completed W-9 before the first payment, advance included.
• A volunteer, unpaid director or candidate repaid only against an accounting gives a full name and mailing address, and also a W-9 if any amount might end up unaccounted.

Where the reimbursement falls on the timeline decides the task:

• Record on file before the trip. The reimbursement is a payment: check the claim against the arrangement, approve it, confirm the payment details if the next section requires it, and pay.
• No record yet. The reimbursement is an onboarding step. Request the record with the engagement letter or invitation, and release nothing, advance included, until it is back and complete and the payment details are confirmed.

How do you make sure the money reaches the traveler, not an impostor?

A W-9 and an approved claim do not show that the account you pay belongs to the traveler; anyone writing from a spoofed or taken-over email account can send both, with bank details. The Federal Trade Commission's small-business cybersecurity guidance says to require employees to call and confirm wire transfer requests and to look up the phone number of the person behind a message yourself, and the FBI's Internet Crime Complaint Center advises secondary channels and/or two-factor authentication to verify requests for changes in account information. Make those checks hold with these rules:

• When. Confirm before the first payment to any payee, advance included, whatever the amount. Before releasing any later payment, check the details against the ones last confirmed and confirm again if they differ; an approval rule that routes only larger payments for approval does not replace this.
• How. For a first payment, call a number that never reached you through the traveler's email or messages, earlier ones included: one you looked up yourself or were given in person. Without one, confirm the details with the traveler in person during the visit before releasing anything. For later confirmations, call the number you last confirmed. Have the traveler state the account and routing numbers, or the mailing address for a check.
• Contact changes. Treat a request to change a phone number, email or address as a change in itself, confirmed as the How rule requires, and never confirm payment details through unconfirmed new contact details.
• Two people. The person who enters or edits payee details does not make the call or approve or release the payment. The caller notes the date, number called and details confirmed, and each month someone who cannot edit payee details reviews the bank's or accounting system's own change history, not a log kept by the editors.
• One person. Where one person does everything, there is no second check: that person calls a number that meets the How rule before entering the details and keeps a dated note, and nobody reviews those changes.
• Outside providers. If an outside bookkeeper or payment service can enter or edit payee details, the same rules bind its staff: they may enter details, but someone at your business makes the call and approves each release.
• Visible details. Pay by bank transfer or check to details you can see and have confirmed, never through a service that routes money to receiving details the payee manages and you cannot see.
• Second sign-in factor. Everyone who enters, confirms or approves payee details or payments uses multifactor authentication on email, the accounting system and the bank.

How should the costs be booked when the payee also charges a fee?

Book accounted travel to travel expense accounts by type, meals to their own account, and the fee to contract labor or professional fees. Publication 463 (2025), for 2025 returns, says the client is subject to the 50% limit on non-entertainment meals a contractor adequately accounts for separately (recheck the percentage in the 2026 edition when it is issued), and can deduct meal reimbursements or allowances a contractor does not adequately account for as payment for services if they are ordinary and necessary business expenses. Booking other unaccounted travel money under contract labor too is a choice, since Publication 463 states that treatment only for meals; it matches the 1099 instructions, which count unaccounted travel reimbursements with the fee.

How the travel reaches you decides the entry:

• Claimed separately from the fee. Book each accounted cost to its travel account and the fee alone to contract labor.
• Billed on the fee invoice. If the invoice itemizes travel with the statement and receipts the arrangement requires, split it between the travel accounts and contract labor; travel billed without them is unaccounted, so book it to its own contract-labor sub-account, such as Contract labor – unaccounted travel, and include it in the payee's total.

For example, with a 4,500.00 fee and 1,115.00 of accounted travel claimed separately, the travel and meals accounts show 1,115.00, contract labor shows 4,500.00, and only the 4,500.00 enters the payee's $2,000 test. An unaccounted 1,115.00 expenses line on the invoice would be booked 4,500.00 to contract labor and 1,115.00 to unaccounted travel under contract labor, so the travel stays visible, and 5,615.00 would enter that test.

Never record travel and fee as one net figure. If the arrangement lets you recover an unspent advance, say 85.00, from the next fee payment, book that payment gross:

The fee still shows in full and the advance clears at its own amount. If the invoice was already entered as a bill, debit accounts payable instead of contract labor.

How do you run and settle an advance?

Run it in this order:

1. Fix the amount and settlement date in the arrangement.
2. Record the advance in an asset account, not as an expense.
3. After the trip, the traveler sends the statement and receipts by the settlement date and returns any unspent balance.
4. The approver checks the statement, and you clear the advance to the travel and meals accounts and record the cash returned.
5. If the accounted costs exceed the advance, pay the difference as an ordinary reimbursement.
6. If any part is neither accounted for nor returned by the date, ask for it in writing and, where the arrangement allows, recover it from the next fee payment, booked gross.

For a fee-paid payee, book a part you cannot recover to unaccounted travel under contract labor and count it in the payee's total, as the 1099 instructions do for travel reimbursements a nonemployee did not account for; Publication 463's contractor rules do not mention advances, so confirm this with a tax adviser if the amount matters. A volunteer, unpaid director or candidate has no fee to book it with, so pay for their flights and hotels directly instead of advancing cash; if an advance was paid, keep any unreturned part in the advance account as owed, file your written requests and get tax advice before writing it off.

What changes for an unpaid volunteer or director?

Neither Publication 463 nor the 1099 instructions say who authorizes a reimbursement when there is no fee or invoice; your organization decides that, through its governing body or the manager who engaged the traveler. The traveler's signed statement with receipts becomes the billing document, and the policy and the approval go in the file. Publication 463's accounted and unaccounted rules are written for independent contractors, which it defines as people who are self-employed and perform services for a customer or client, and the 1099 exclusion covers only expense reimbursements paid to volunteers of nonprofit organizations, so neither settles a flat amount paid to a volunteer or unpaid director. The 1099 instructions do not say whether an unpaid director counts as a volunteer, or how a for-profit business's unpaid volunteer or speaker is treated; get tax advice on these points, and on any flat amount paid, before year-end reporting.

What changes for a job candidate?

With no contract, put the terms in the written invitation: what you will pay for, whether you will book travel directly, which receipts to send and by when. Publication 525 tells a candidate whose prospective employer asks them to interview and pays an allowance or reimburses their travel to include in income only the amount received that is more than actual expenses. That rule speaks to the candidate's income, not to whether you must report an amount above the candidate's costs, so repay only accounted actual costs or pay suppliers directly; if a round sum has already been paid, get tax advice before year-end reporting. Create the payee record for this one payment, confirm the payment details like any first payment, and mark the record inactive once the reimbursement is paid and the file is complete, keeping both; treat any later reactivation as a change to confirm.

What goes in the reimbursement file, and how long must it be kept?

Each file should hold these items:

Publication 463 (2025) says to keep records as long as they may be needed for the administration of any provision of the Internal Revenue Code, which generally means 3 years from the date you file the income tax return on which the deduction is claimed; a return filed early is considered filed on its due date. That 3-year period is stated for records supporting a deduction or an item of income. Publication 463 and the W-9 requester and 1099 instructions give no number of years for a Form W-9, for the records behind an information-return position, or for a nonprofit or other organization that claims no deduction for the payment. Keep the whole file, W-9 included, at least that long, and confirm the period before discarding any of it. Publication 463 refers readers to Publication 583 for a fuller explanation of how long to keep records.
