Business vs. Nonbusiness Bad Debt (2026): Deduct a Loan to a Client or Friend on Schedule C or as a Capital Loss

Published: October 29, 2026 · Reading time: 10 min

TL;DR: If you lent cash and can't collect it, the tax result depends on one question: was the debt connected to your business? A business bad debt (for example, a loan to a client or supplier made for a business reason) is deducted on Schedule C, in full when totally worthless and in part if you charge the partly worthless amount off. A nonbusiness bad debt (for example, a personal loan to a friend) must be totally worthless and is only a short-term capital loss, which offsets capital gains plus up to $3,000 of other income a year. On an $8,000 loan with no capital gains, that is $8,000 on Schedule C in one year (about $1,130 less self-employment tax) versus $3,000 + $3,000 + $2,000 over three years and no self-employment tax savings. A cash-method freelancer can't use either one for an unpaid invoice.

Most freelancers who get stung on a loan do the same thing: they go looking for the "bad debt" deduction and assume there is only one. There are two, they are taxed very differently, and the dividing line is not how much you lost or how well you knew the borrower.

This guide compares the two side by side using the statute, the Treasury regulations and the IRS's own publications, works one $8,000 loan through both paths with every number computed, and flags where the answer depends on facts a CPA or EA should review. It is about cash you lent. Invoices a client never paid are a separate problem, covered in Can You Write Off an Unpaid Invoice? and again below.

The One Question That Sorts Every Bad Debt

Internal Revenue Code section 166 allows a deduction for a debt that "becomes worthless within the taxable year," but for anyone other than a corporation it carves out a second category. Section 166(d)(2) defines a nonbusiness debt as one other than:

"a debt created or acquired (as the case may be) in connection with a trade or business of the taxpayer"

or a debt whose worthlessness loss is "incurred in the taxpayer's trade or business." Everything outside those two doors is a nonbusiness debt. IRS Topic 453 turns the second door into a practical test: a debt is closely related to your trade or business "if your primary motive for incurring the debt is business related."

Two things in that framing surprise people:

• The borrower's identity is not the test. The Treasury regulations say the character of the debt is "determined by the relation which the loss resulting from the debt's becoming worthless bears to the trade or business of the taxpayer," and that if the relation is proximate in the conduct of the business, the debt is a business debt. The regulation also says: "The use to which the borrowed funds are put by the debtor is of no consequence in making a determination under this paragraph." What matters is why you lent it, not what the borrower did with it.
• It is a question of fact. The regulation says whether a debt is a nonbusiness debt "is a question of fact in each particular case." No checklist guarantees the result, which is why documentation matters.

Business Bad Debt: What It Looks Like

IRS Topic 453 lists "Loans to clients, suppliers, distributors, and employees" among its examples of business bad debts, alongside credit sales to customers and business loan guarantees. IRS Publication 334 adds that if you lend money to a client, supplier, employee or distributor for a business reason and can't collect it after trying, you have a business bad debt.

Picture a freelance developer who lends a long-term client $8,000 to cover payroll so a project that pays her much more can be finished. The loan was made to protect a business relationship, which is a business motive, and if the client collapses the loss lands on her Schedule C.

What a business bad debt gets you:

• A Schedule C deduction. Topic 453 says you can deduct a business bad debt on Schedule C, Profit or Loss From Business. Because it reduces net profit, it also reduces the net earnings that self-employment tax is figured on.
• Partial deductions. For a business debt that is only partly worthless, Pub. 334 says "your deduction is limited to the amount you charged off on your books during the year." A dated entry in your books is the proof.
• No charge-off needed when the debt is totally worthless. Pub. 334 says you don't have to make an actual charge-off on your books for a totally worthless debt, though it suggests you may want to.

What it does not get you: a deduction for an unpaid invoice you never reported as income (see the cash-method section below), or a deduction for a gift.

Nonbusiness Bad Debt: What It Looks Like

IRS Publication 550 gives the cleanest example: "An architect made personal loans to several friends who were not clients. The architect could not collect on some of these loans. They are deductible only as nonbusiness bad debts because the architect was not in the business of lending money and the loans do not have any relationship to the architect's business."

Swap in a freelancer. Lending $8,000 to a college friend who is opening a café has no connection to your design practice, so it is a nonbusiness debt even though you are self-employed.

The consequences are tougher:

• It must be totally worthless. Topic 453 states: "Nonbusiness bad debts must be totally worthless to be deductible. You can't deduct a partially worthless nonbusiness bad debt."
• It is a capital loss, always short-term. Section 166(d)(1)(B) treats the loss as "a loss from the sale or exchange, during the taxable year, of a capital asset held for not more than 1 year." So how long you waited makes no difference: it is short-term.
• It is capped. Pub. 550 says a capital loss deduction is the lesser of "$3,000 ($1,500 if you are married and file a separate return)" or your total net loss, with any unused part carried over to the next year.
• It does not touch self-employment tax. Section 1402(a)(3)(A) excludes from net earnings from self-employment any gain or loss "which is considered as gain or loss from the sale or exchange of a capital asset." A capital loss therefore does not lower your SE tax base.
• It needs a statement. You attach a description of the debt, the debtor and any business or family relationship, your collection efforts, and why you decided it was worthless.

Side by Side

A Worked Example: The Same $8,000, Two Different Outcomes

Dana is a single freelance developer. In 2026 her net profit from Schedule C is $90,000 before any bad-debt deduction. She has no other income and no capital gains or losses besides the one below, and her net earnings are well under the Social Security wage base. In 2026 a loan of $8,000 becomes totally worthless. She documented the loan with a signed note, asked for repayment several times and has proof the borrower closed the business.

Path A: the borrower was a client and the loan was a business loan. The $8,000 is a Schedule C deduction. Net profit drops from $90,000 to $82,000.

Path B: the borrower was a friend and the loan was personal. The $8,000 is a short-term capital loss. With no capital gains to absorb it, Dana deducts $3,000 in 2026, $3,000 in 2027 and $2,000 in 2028 (the carryover rules in Pub. 550), assuming no other capital gains or losses in those years.

Self-employment tax is figured on 92.35% of net profit at 15.3% (section 1402(a)(12) sets the 92.35%, which is one minus half the combined rate; 15.3% is the 12.4% Social Security plus 2.9% Medicare rate). Computed:

So in 2026 Path A deducts $5,000 more, and also saves $1,130.37 of self-employment tax that Path B never gets, in any year. The capital-loss path eventually deducts the full $8,000 against income, but over three years and without the SE tax benefit.

This example does not apply an income tax rate, because the point is the timing and the SE-tax difference, and Dana's taxable income would need to be derived from facts beyond the ones stated. It also ignores the SE tax deduction for half of SE tax and the qualified business income deduction, both of which change the exact income-tax result.

If the facts change: had Dana recovered $2,500 and written off the other $5,500, Path A would allow a deduction for the $5,500 only to the extent she charged it off on her books that year, while Path B would allow nothing until the whole remaining debt was totally worthless.

Three Things That Get Freelancers Into Trouble

1. Calling a gift a loan

Topic 453 is blunt: "If you lend money to a relative or friend with the understanding the relative or friend may not repay it, you must consider it as a gift and not as a loan, and you may not deduct it as a bad debt." The regulations require a "bona fide debt," and say that "a gift or contribution to capital shall not be considered a debt for purposes of section 166."

Practically: a signed note, a repayment schedule and an actual request for repayment all help show you meant it as a loan. Handing a friend cash with no paperwork and no plan to collect looks like a gift. If you also charge no interest, see below-market loans, which have their own rules.

2. Putting money into a business as capital, then calling it a loan

Pub. 334 says you can't claim a bad debt deduction for a loan you made to a corporation "if, based on the facts and circumstances, the loan is actually a contribution to capital." A debt evidenced by a corporate security with coupons or in registered form is also outside section 166 altogether (section 166(e)), and is handled under the worthless-securities rules instead. If you put money into your own incorporated business, read Section 1244 stock and owner's contribution vs. owner's loan before you assume a bad-debt deduction exists.

3. Expecting a bad-debt deduction for an unpaid invoice

Pub. 334 spells out the cash method: "You can't take a bad debt deduction for amounts owed to you that you have not received and can't collect if you never included those amounts in income." A cash-method freelancer reports income only when paid, so an invoice that never gets paid was never income and there is nothing to write off. The IRS Schedule C instructions for bad debts likewise describe debts "from sales or services that were included in income." Accrual-method filers are the exception. See cash vs. accrual accounting for how the method is chosen. A cash loan is different from an invoice: your basis is the cash you actually handed over.

Proving Worthlessness Without a Lawsuit

You can take a bad debt deduction only in the year the debt becomes worthless, and you do not have to wait until it is due. Topic 453 says a debt is worthless "when the surrounding facts and circumstances indicate there's no reasonable expectation that the debt will be repaid" and that you must establish you have "taken reasonable steps to collect the debt."

You do not need a judgment. Treasury Regulation 1.166-2(b) says legal action is not required where the circumstances indicate the debt is worthless and that legal action "would in all probability not result in the satisfaction of execution on a judgment." Bankruptcy of the debtor is generally an indication of worthlessness of at least part of an unsecured, unpreferred debt under the same regulation.

Build a file as you go:

1. The signed note or written agreement, and proof you actually sent the money
2. Every demand: dated emails, letters and texts
3. Evidence of the borrower's condition: a bankruptcy notice, a closed business, a returned-mail pattern
4. A dated memo of the day you concluded there was no reasonable expectation of repayment
5. For a business bad debt that is only partly worthless, the dated charge-off entry in your books

Records like these are exactly what a receipt and records system is for, since a bad-debt claim is only as strong as its paper trail.

If You Missed the Deduction

A bad debt belongs to the year it became worthless. If you didn't claim it that year, Pub. 550 says you can file Form 1040-X for that year. Pub. 334 gives the deadline for a totally worthless debt as the later of "7 years from the date your original return was due (not including extensions)" or 2 years from the date you paid the tax. The ordinary refund window is shorter, so this is one of the few places the tax code gives you extra time. The mechanics of amending are in how to amend a Schedule C.

A debt can't be deducted in a year after the one in which it becomes totally worthless, so the real question is always "which year did it go bad?" If you later collect something you already deducted, the Schedule C instructions say to include it as income in the year collected.

Which Treatment Fits You? A Quick Decision Guide

• You lent cash to a client, vendor or subcontractor to keep work going. Likely a business bad debt, if you can document the business motive. Deduct on Schedule C in the year it becomes worthless.
• You lent cash to a friend, relative or an unrelated venture. Likely a nonbusiness bad debt: totally worthless only, short-term capital loss, $3,000 cap on net losses against other income.
• Your client never paid an invoice and you use the cash method. No bad-debt deduction. Your unreimbursed job costs were already deductible when you paid them.
• You put money into your own corporation. Probably neither: look at stock basis and, if it qualifies, section 1244.
• You are unsure whether the loan was a gift. Treat it with caution, document it now and ask a professional.

Frequently Asked Questions

Can I deduct money I lent to a client who never paid it back?

Often yes, as a business bad debt. IRS Topic 453 lists loans to clients, suppliers, distributors and employees as examples of business bad debts, and says a debt is closely related to your trade or business if your primary motive for incurring the debt is business related. A business bad debt is deducted on Schedule C. Three conditions apply: the loan must be a genuine debt (a gift or a capital contribution is not a debt), you must have actually lent the cash, and the debt must have become worthless in the year you deduct it, which means you took reasonable steps to collect and there is no reasonable expectation of repayment. If you lent the money to a relative or friend knowing it might not be repaid, the IRS treats it as a gift, not a loan. Because the classification turns on your facts, confirm it with a CPA or EA before you file.

What is the difference between a business and a nonbusiness bad debt?

A business bad debt was created or acquired in your trade or business, or was closely related to it when it became worthless. It is deducted on Schedule C, and it can be deducted in part when it is only partly worthless, but only to the extent you charged the part off on your books during the year. Every other bad debt is a nonbusiness bad debt: it must be totally worthless, it is a short-term capital loss reported on Form 8949, and it is subject to the capital loss limits (a net loss reduces ordinary income by no more than $3,000 a year, or $1,500 if married filing separately, with the rest carried forward). Whether a debt is business or nonbusiness is a question of fact, so a CPA or EA should review borderline loans.

Can I write off an unpaid invoice as a bad debt?

Usually not if you use the cash method, which most freelancers do. IRS Publication 334 says that if you use the cash method you can't take a bad debt deduction for amounts owed to you that you have not received and can't collect if you never included those amounts in income. The deduction for an unpaid invoice is available only if the amount was already included in your gross income, as it would be under accrual accounting. The out-of-pocket costs of the job (materials, subcontractors, software) were already deductible when you paid them. A cash loan is different, because you have a basis in cash you handed over. Ask a CPA or EA which method your return actually uses before you claim anything.

Do I have to sue the borrower before I can claim a bad debt?

No. IRS Topic 453 says you must establish that you've taken reasonable steps to collect the debt, and that it's not necessary to go to court if you can show that a judgment from the court would be uncollectible. Treasury Regulation 1.166-2(b) says legal action is not required when the surrounding circumstances indicate the debt is worthless and that legal action would in all probability not result in satisfaction of a judgment. Keep your demand letters, emails and any bankruptcy notice as proof. You can only deduct the debt in the year it becomes worthless, so ask a CPA or EA to help you pin down that year.

How do I report a nonbusiness bad debt, and why is it capped at $3,000?

You report a totally worthless nonbusiness bad debt as a short-term capital loss on Form 8949, Part I, with the debtor's name and the words bad debt statement attached in column (a), your basis in column (e) and zero in column (d), and you attach a statement describing the debt, the debtor and any business or family relationship, your collection efforts and why you decided it was worthless. A capital loss first offsets capital gains. Any net loss then reduces other income by the lesser of $3,000 ($1,500 if married filing separately) or the net loss, and the unused part carries to the next year. So an $8,000 nonbusiness bad debt with no capital gains is deducted as $3,000, $3,000 and $2,000 over three years. It also does not reduce self-employment tax. Ask a CPA or EA to review the statement before you file.

Can I deduct part of a loan if I only collect some of it?

For a business bad debt, yes, but only to the extent you charged the partly worthless amount off on your books during the year, according to IRS Publication 334. For a nonbusiness bad debt, no: IRS Topic 453 says nonbusiness bad debts must be totally worthless to be deductible and that you can't deduct a partially worthless nonbusiness bad debt. If the loan is a business debt, make a dated charge-off entry in your books in the year you take the deduction, and if you later collect what you deducted, include it as income in the year you collect it. Whether a debt is business or nonbusiness decides this, so a CPA or EA should confirm which one you have.

What if I didn't deduct the bad debt in the year it went bad?

You may be able to amend. IRS Publication 550 says that if you do not deduct a bad debt on your original return for the year it becomes worthless, you can file Form 1040-X for that year, and Publication 334 says that for a totally worthless debt the claim must be filed by the later of 7 years from the date your original return was due (not including extensions) or 2 years from the date you paid the tax. That is longer than the usual three-year refund window. The deduction belongs to the year the debt became worthless, not to the year you noticed, and a debt can't be deducted in a year after the one in which it became totally worthless. Have a CPA or EA confirm the right year and the deadline before you amend.
