A disbursement is a payment your firm makes to a third-party vendor on behalf of a specific client, with the expectation that the client will reimburse you dollar for dollar. It is not a business expense. Handled correctly, it never touches your profit and loss statement. Instead, it creates a short-term receivable on your balance sheet that disappears the moment the client pays you back.
That classification matters. Treating a client advance as an ordinary expense can inflate your reported income, misstate your deductions, and, in regulated professions like law, create ethical problems on top of the tax ones.
How a Disbursement Differs From an Operating Expense
The dividing line comes down to one question: who ultimately bears the cost?
An operating expense is a cost your firm absorbs to run the business. Office rent, payroll, software subscriptions. You deduct it against revenue, and no one reimburses you. A disbursement works differently. Your firm fronts the money, but the financial burden belongs to the client. You are acting as a temporary banker, not spending your own resources.
This changes how you record the payment. An operating expense reduces your net income through a debit to an expense account on the income statement. A disbursement bypasses the income statement entirely. You debit a balance sheet asset account (the client owes you money) and credit cash (your bank balance drops). When the client reimburses you, the transaction reverses, and your profit stays untouched. The payment is revenue-neutral.
The IRS cares about this distinction. Courts have consistently held that costs advanced on behalf of a client are treated as loans for tax purposes, not deductible business expenses. A firm cannot deduct disbursements under the ordinary and necessary business expense rules because those costs belong to the client. If you deduct client advances as expenses and the client later reimburses you, you have created a mismatch the IRS will challenge.
Common Examples of Disbursements
Disbursements show up most frequently in professional services where firms routinely pay vendors to keep client work moving forward. Law firms, accounting practices, and consulting engagements all generate them.
In legal practice, the most common ones include:
- Court filing fees — mandatory government charges to initiate a lawsuit, file a motion, or register a corporate entity.
- Court reporter and transcript costs for depositions, hearings, or trial proceedings.
- Expert witness fees paid to specialists who provide testimony or prepare reports.
- Process server fees for serving legal documents on opposing parties.
- Travel directly tied to a client matter, such as airfare, lodging, or mileage for a deposition or site inspection.
Outside law, a management consultant might pay for a specialized market research report required for a particular engagement. An accounting firm might purchase industry-specific software licenses needed only for one audit. The pattern is the same: the cost is directly traceable to a single client and contractually recoverable.
The line can blur with smaller items like photocopying and courier services. The test does not change. Was the cost incurred specifically for a client matter, and does the engagement agreement require the client to reimburse it? General business travel, even if it happens to benefit a client relationship, is an operating expense, not a disbursement.
How to Record a Disbursement Correctly
When your firm pays $1,000 for a client’s court filing fee, the entry looks like this:
- Debit: Client Cost Advances (a balance sheet receivable account) — $1,000
- Credit: Cash — $1,000
The debit records what the client owes you. The credit decreases your cash balance. No expense account appears anywhere in the entry. The payment has zero effect on your income statement.
When the client reimburses you, the entry reverses:
- Debit: Cash — $1,000
- Credit: Client Cost Advances — $1,000
Cash goes back up, the receivable disappears, and the cycle is complete. Your firm’s profit sits exactly where it was before either transaction occurred.
This only works if your accounting system can tag each advance to a specific client and matter number. Without that granularity, disbursements from different clients bleed together, making it nearly impossible to bill accurately or defend your records in an audit. Every advance should have a corresponding vendor invoice or receipt linked to the client matter file. Attaching a copy of the third-party invoice to the client bill is the documentation that justifies the charge.
Tax Treatment and 1099 Reporting
Why the IRS Treats Advances as Loans
The IRS position is straightforward: when your firm advances money for a client’s costs, that payment is a loan to the client, not a current business expense. The advance sits on your books as a receivable until the client reimburses you or the debt becomes worthless.
This treatment has been tested in court, most notably in cases involving law firms that advanced litigation costs on contingency matters. Firms argued that because reimbursement depended on winning, the advances were uncertain enough to be deducted immediately. Courts rejected that argument, finding that even partial recovery rates still represented a meaningful expectation of reimbursement. The advances had to be capitalized as receivables, not expensed.
When a client does reimburse you, the reimbursement is not income. It simply settles the receivable. But if you have been incorrectly deducting the advances as expenses, the reimbursement creates phantom income, because you already took the deduction. Recording it correctly from the start avoids the problem entirely.
Your 1099 Obligations
Even though a disbursement is a pass-through cost, your firm may still have reporting obligations to the IRS. If you pay $600 or more during the year to any individual non-employee — an expert witness, court reporter, consultant, or investigator — you are generally required to file Form 1099-NEC reporting that payment as nonemployee compensation.1Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC The $600 threshold is cumulative across the year, so two separate $400 payments to the same expert witness trigger the filing requirement.
The fact that your client will ultimately bear the cost does not relieve you of this obligation. Your firm made the payment, and the IRS considers the payor responsible for information reporting. Firms that overlook 1099 filings for disbursed payments risk penalties for each missing form.
What Happens When You Mark Up a Disbursement
Everything above assumes the firm bills the client at exact cost. A pure pass-through. Some firms add a markup on certain disbursements, charging the client more than the firm actually paid the vendor. That markup changes the tax and accounting treatment.
A reimbursement at cost is revenue-neutral and never touches the income statement. But the moment you charge $1,200 for a $1,000 expense, the extra $200 is revenue. That markup must be recorded as income on your profit and loss statement, and it is subject to income tax. The $1,000 settles the receivable, and the $200 goes to a revenue account.
Engagement agreements should be clear about whether disbursements are billed at cost or at a premium. Many firms disclose that certain internal services, such as photocopying, electronic research, or local deliveries, are charged at rates that may include a markup or are based on reasonable estimates rather than exact vendor invoices. Burying a significant markup inside a line item labeled “disbursement” erodes trust and, in legal practice, can raise ethical issues around fee transparency.
Trust Account Rules for Lawyers
For lawyers, the stakes around disbursement accounting extend beyond tax compliance into professional ethics. Every state has adopted some version of the rule requiring lawyers to keep client funds completely separate from firm operating funds.2American Bar Association. Rule 1.15 – Safekeeping Property Client money goes into a dedicated trust account, often called an IOLTA account, and stays there until the lawyer earns the fee or incurs the expense.
When a client provides a retainer that covers anticipated disbursements, those funds must remain in the trust account until the firm actually makes the third-party payment. Pulling money from the trust account before the expense is incurred, or using one client’s trust funds to cover another client’s disbursement, is commingling. Consequences range from disciplinary proceedings to disbarment, and criminal prosecution is possible when the conduct rises to the level of misappropriation.
Lawyers also have specific authority to advance litigation costs with repayment contingent on the outcome of the case.3American Bar Association. Rule 1.8 – Current Clients Specific Rules A firm handling a contingency case can front filing fees, expert witness costs, and similar expenses knowing the client will only reimburse if the case succeeds. The accounting treatment does not change. The advance stays on the balance sheet as a receivable until it is repaid or written off.
When a Client Never Reimburses You
Not every disbursement gets paid back. When a receivable goes bad, eventually you need to write it off, but the rules differ depending on whether the debt is partially or completely worthless.
Under federal tax law, a wholly worthless debt may be deducted in the year it becomes worthless.4Office of the Law Revision Counsel. 26 USC 166 – Bad Debts For a partially worthless debt, the IRS allows a deduction only for the portion you have charged off during the tax year. You must demonstrate the debt is actually worthless, not just slow to collect. That means showing you took reasonable steps to recover the money and that further collection efforts would be futile.5Internal Revenue Service. Topic No. 453, Bad Debt Deduction
You do not have to file a lawsuit to prove worthlessness, but you do need a paper trail. Demand letters, records of follow-up calls, returned mail, and documentation of the client’s financial situation all help establish that collection is genuinely hopeless. The deduction must be taken in the year the debt becomes worthless, not the year you finally get around to cleaning up your books. Miss that window and you may need to file an amended return.
This is where meticulous matter-level tracking pays off. If you cannot prove the original advance was a legitimate client receivable tied to a specific matter, defending the bad debt deduction gets much harder.
