Refund of a Business Expense You Deducted Last Year: Schedule C Line 6 and the Tax Benefit Rule (2026 Guide)

Published: October 20, 2026 · Reading time: 11 min

TL;DR: If you deducted a business cost on your 2025 Schedule C and the money comes back to you in 2026 (a cancelled conference, a returned insurance premium, a prorated software refund), it is generally income in 2026 on Schedule C line 6, not a reduction of a 2026 expense. A refund received in the same year you paid the cost simply reduces that year's deduction. The amount you include is capped at what you actually deducted, so a 70% business-use phone bill produces a 70% recovery. Under the tax benefit rule, the part of the earlier deduction that did not reduce your tax can be excluded, but you must attach a computation. Depreciation is the exception: it follows the recapture rules instead. In the worked example below, four refunds totaling $1,000 produce $970 on line 6.

Every freelancer gets money back eventually. A conference gets cancelled and the registration fee is refunded in March. A software company prorates the unused months of an annual plan. Your liability insurer finishes its premium audit and returns part of what you paid. A carrier refunds an overcharge.

The question is not whether the refund is real money. It is which year it belongs to and where it goes on the return. Get it wrong one way and you either double-dip (deduct a cost in 2025 that you got back in 2026, then quietly net it against a 2026 expense line that never included it). Get it wrong the other way and you pay tax on money that never gave you a tax benefit in the first place.

This guide walks through the rule Publication 334 and Publication 525 actually state, how it maps to Schedule C, the cases where you include less than the full refund, and a worked example you can check.

The Rule in One Paragraph

Publication 334 (2025), in its discussion of other business income, says that if you recover a bad debt or any other item deducted in a previous year, you include the recovery in income on Schedule C. It then adds the exception: if all or part of the deduction in earlier years did not reduce your tax, you can exclude the part that did not reduce your tax, and if you exclude part of the recovery, you must include with your return a computation showing how you figured the exclusion.

That second half is the tax benefit rule, and it comes from section 111(a) of the Internal Revenue Code, which excludes from gross income the recovery of an amount deducted in a prior year to the extent that amount did not reduce tax. Publication 525 defines a recovery as a return of an amount you deducted or took a credit for in an earlier year, and says you include it in income in the year you receive it, up to the amount by which the deduction reduced your tax in the earlier year.

Three consequences follow, and the rest of this article is about them:

1. Timing. The recovery is income in the year you get the money back, not a correction to the year you deducted it.
2. A cap. You never include more than you deducted.
3. A possible exclusion. If the earlier deduction did not lower your tax, part or all of the recovery may stay out of income.

Where It Goes: Schedule C Line 6, Not the Original Expense Line

The 2025 Instructions for Schedule C tell you to report on line 6 business income not reported elsewhere in Part I, and they list examples including bad debts you recovered, interest on notes and accounts receivable, state gasoline or fuel tax refunds you received, prizes and awards related to your business, and other kinds of miscellaneous business income. A recovered business deduction fits that description, so line 6 is where it generally belongs. (The 2026 instructions had not been released when this was written; check them when you file.)

Publication 334 explains what line 6 does: you enter the income on line 6 and add it to gross profit, and the result is gross business income. From there it flows into net profit on line 31, which is also the figure Schedule SE starts from. So an included recovery raises both your income tax base and your self-employment tax base, in the same way the original deduction lowered them.

Why not just shrink this year's expense line? Because this year's expense line never contained the refunded cost. If you paid $600 for a 2025 conference and deducted it in 2025, then netted the March 2026 refund against your 2026 travel or education costs, your 2026 Schedule C would understate a real 2026 expense and hide a real 2026 income item. The net effect on profit can be identical, which is why people do it, but it misstates two lines and breaks the paper trail between your books and your return. For a deeper look at what else lands on this line, see Schedule C line 6 explained.

Refunds you receive are not refunds you give

Do not confuse this with line 2, returns and allowances. The Schedule C instructions describe a sales return on line 2 as a cash or credit refund you gave to customers who returned defective, damaged or unwanted products. That is a refund flowing out of your business. This article is about refunds flowing in. And if you had to give back income you reported in an earlier year, that is a different rule again, covered in the claim of right doctrine and section 1341.

Same-Year Refunds: No Income, Just a Smaller Deduction

Publication 525 is direct about this: if the refund or other recovery and the expense occur in the same year, the recovery reduces the deduction and is not reported as income.

Pay $400 for an online course in April 2026, get the full $400 back in June 2026, and there is nothing to report on line 6 and nothing to deduct. If you got $150 back, your 2026 deduction is $250.

This is why the year you paid matters. Most freelancers are on the cash method, so the year of the deduction is generally the year of payment. If you are not sure which year a receipt belongs to, see which tax year a receipt belongs to on the cash basis.

One refund, two years of payments

Publication 525 also covers a refund that relates to amounts you paid in two or more separate years: you allocate the recovered amount between those years on a pro rata basis. The part tied to a prior year is a recovery; the part tied to the current year reduces the current-year deduction.

Suppose you paid a professional liability policy's premiums of $900 in 2025 and $300 in 2026, and the insurer refunds $240 in 2026. You paid 75% of the total ($900 ÷ $1,200) in 2025, so $180 of the refund is a recovery of a 2025 deduction and goes to line 6 (assuming the 2025 deduction reduced your tax). The other $60 is tied to 2026 and simply reduces your 2026 insurance deduction on line 15.

The Cap: You Only Recover What You Deducted

A recovery is a return of an amount you deducted, so the starting point is the deduction you actually claimed, not the refund check.

Publication 525's itemized-deduction discussion puts the limit plainly: the amount you include is limited to the smaller of the amount deducted or the amount recovered. Publication 334 says the same thing about bad debts: the amount you include is limited to the amount you actually deducted.

This matters most for mixed-use costs, which freelancers have plenty of:

• Phone and internet. If you deducted 70% of a phone bill as business use and the carrier later refunds $100 in cash for overbilling on that bill, you deducted only $70 of the overcharge. The $70 is the recovery to consider; the personal $30 was never deducted. A credit applied to a later bill is different: it lowers what you actually pay for that later service, so figure that year's phone deduction on the amount you paid and do not also report the credit on line 6.
• Home office actual expenses. A refund of a utility deposit or an insurance overcharge on your home relates only partly to the business share you deducted on Form 8829.
• Costs you never deducted. If you never claimed a cost at all, a refund of it is not a recovery of a deduction. If you only now realize you missed a deduction in an open year, that is an amendment question, covered in how to amend Schedule C, not a line 6 question.

When You Include Less: The Tax Benefit Rule in Practice

For most working freelancers with a normal, profitable prior year, the earlier deduction reduced tax dollar for dollar and the full recovery (up to the cap) is included. The exclusion matters in thinner years. Publication 525's section on nonitemized deduction recoveries, which covers deductions you took in figuring adjusted gross income, gives the mechanics:

• The general rule. If you recover an amount you deducted in an earlier year when figuring AGI, you generally include the full amount in income in the year received.
• Negative taxable income. If your taxable income for the prior year was negative, the recovery you must include is reduced by that negative amount. Publication 525 states the test for 2024 as the sum of Form 1040 lines 12 and 13 being more than line 11. The 2025 Form 1040 is numbered differently (taxable income is line 15, built from lines 11b, 12e, 13a, 13b and 14), so compare the deductions your 2025 return actually took, including any Schedule 1-A deductions, against your 2025 adjusted gross income, or ask your preparer whether the result was negative.
• Net operating losses. If you had a net operating loss in a prior year, you adjust taxable income for the NOL carryover. Section 111(c) and Publication 525 both treat an increase in a carryover that has not expired as having reduced your tax, so a deduction that only grew an NOL still counts as a benefit. See the Schedule C net operating loss guide.
• Unused credits. If you had unused tax credits in the earlier year, you refigure that year's tax with the recovery added back. If the tax after credits does not change, the deduction gave you no benefit and you do not include the recovery.

Whenever you exclude part of a recovery, Publication 334 requires you to include a computation with your return showing how you figured it.

What the tax benefit rule does not grant. It does not let you exclude a recovery because the deduction saved you "only a little" tax; any reduction counts up to the amount deducted. It does not let you refigure the old year at today's rates or move the income back to the old year. And it does not override the depreciation exception below. One open question: the deduction also lowered your self-employment tax in the earlier year, and we did not find guidance in Publication 334 or Publication 525 on how an excluded recovery interacts with self-employment tax. If you are relying on an exclusion, have a CPA or EA confirm the treatment.

The Depreciation Exception

Publication 334 says its recovery rule does not apply to depreciation, which you recover under the depreciation recapture rules instead. The best-known freelancer case: if business use of listed property falls to 50% or less in a later year, you may have to recapture part of the depreciation or section 179 deduction, figured in Part IV of Form 4797 and reported on Schedule C. The Schedule C instructions place that recapture on line 6 too.

So if the item you got money back on was a depreciable asset (a laptop you expensed under section 179, a camera body you are depreciating), do not run it through the tax benefit rule. A rebate on a capital purchase or a return after you claimed a deduction raises basis and recapture questions this article does not cover. Start with depreciation recapture for freelancers and ask a CPA or EA.

Other Refunds and Credits That Behave Differently

Not every dollar coming back to you is a line 6 recovery. A few common ones, with what the sources say:

Two cross-references worth reading: unpaid invoices and the bad debt deduction explains why a cash-method freelancer usually has no bad debt to deduct (and therefore no bad debt to recover), and credit card rewards and business deductions covers cash back on business cards. If the money came back through a lawsuit or settlement rather than a refund, see lawsuit settlement income on Schedule C.

Worked Example: A UX Designer's 2026 Refunds

Maya is a sole-proprietor UX designer on the cash method. Her 2025 Schedule C showed a solid profit, her 2025 Form 1040 had positive taxable income, she had no unused credits and no NOL. So every 2025 deduction below reduced her tax, and the tax benefit rule does not trim anything. In 2026 she receives five refunds:

How the line 6 figure is built:

• The first three refunds are full recoveries of 2025 deductions: $600 + $180 + $120 = $900.
• The phone refund is capped at the business share Maya deducted: 70% × $100 = $70.
• The course refund is a same-year refund. Publication 525 says it reduces the 2026 deduction and is not reported as income, so it contributes $0 to line 6.
• Line 6: $900 + $70 = $970. Excluding the same-year course refund, the four prior-year refunds total $1,000, of which $970 is included.

Maya reports $970 on line 6. It flows into gross income and net profit, and from there into Schedule SE like any other business income. She does not amend her 2025 return.

The same refunds in a thin year

Now change one fact. Suppose the same $1,000 of prior-year refunds went to Jordan, a first-year freelancer whose 2025 Schedule C profit was small and whose 2025 deductions exceeded 2025 adjusted gross income by $400: negative taxable income of $400. Jordan had no business loss, so no NOL, and no unused credits. Taking the same $970 recoverable amount (after the phone cap), Publication 525 says the amount Jordan must include is reduced by the negative taxable income: $970 − $400 = $570 on 2026 line 6, with a computation attached to the return showing how the $400 exclusion was figured. Because we did not find guidance on how the excluded $400 interacts with self-employment tax, Jordan should have a CPA or EA confirm the computation.

Common Mistakes to Avoid

1. Netting a prior-year refund against this year's expense line. It can leave net profit unchanged while misstating two lines. Prior-year recoveries generally go on line 6.
2. Reporting a same-year refund as income. If you paid and got the money back in the same year, you just have a smaller deduction. Reporting it on line 6 and keeping the full deduction is the double-count in reverse.
3. Including the personal share. If you only deducted 70% of a bill, only 70% of its refund is a recovery of a business deduction.
4. Amending the old year instead of reporting the recovery. The tax benefit rule works in the year of receipt. Amendment is for deductions that were wrong when claimed.
5. Excluding without attaching the computation. Publication 334 requires it. An exclusion with no support is an unexplained income gap.
6. Running a depreciable asset through the recovery rule. Depreciation and section 179 follow the recapture rules, not the tax benefit rule.
7. Losing the original receipt. You cannot show what you deducted, in which year, or at what business percentage without it. See Schedule C recordkeeping by line.

How CentSense Helps

The whole analysis turns on one question: what did you deduct, and when? That is a receipts question.

• AI receipt scanning: the free plan includes 10 AI receipt scans per month, and Solo ($5/month) adds unlimited scans, so the original conference invoice, insurance bill or software receipt is on file with its date and amount when the refund arrives a year later.
• Mileage tracking for the trips that sit alongside those expenses.
• CSV export so your CPA or EA can match a refund notice to the original deduction without a reconstruction exercise.

CentSense does not decide whether a refund is a recovery or figure a tax benefit exclusion; that is the computation to review with your tax professional.

Frequently Asked Questions

Is a refund of a business expense I deducted last year taxable?

Usually, yes. Publication 334 says to include a recovery of an item deducted in a previous year in income on Schedule C, in the year you receive it. If part of the earlier deduction did not reduce your tax, you can exclude that part, but you must attach a computation showing how you figured it. You never include more than you deducted, and depreciation follows the recapture rules instead. Ask a CPA or EA how this applies to your return.

Where do I report a recovered business expense on Schedule C?

Generally on line 6, Other income. The 2025 Schedule C instructions put business income not reported elsewhere in Part I on line 6, including recovered bad debts and other miscellaneous business income. Line 6 is added to gross profit, so the recovery increases net profit on line 31 and the self-employment tax base on Schedule SE. Do not subtract a prior-year refund from this year's expense line.

What if I paid the expense and got the refund in the same year?

Then it is not income. Publication 525 says a same-year recovery reduces the deduction and is not reported as income. If one refund covers payments made in two or more years, allocate it pro rata: the prior-year part is a recovery, and the current-year part reduces this year's deduction.

Do I have to amend last year's return when I get a refund of a deducted expense?

Generally no, if the original deduction was correct when you claimed it. The tax benefit rule has you include the recovery in the year you receive it rather than refiguring the earlier year. If the original deduction was wrong when you filed, the fix may be an amended return instead, so ask a CPA or EA which case you are in.

What if last year's deduction did not actually lower my tax?

You may be able to exclude part or all of the recovery under section 111. Publication 525 reduces the included amount by any negative prior-year taxable income, treats an increase to an unexpired carryover such as an NOL as a tax benefit, and requires refiguring the earlier tax if you had unused credits. Publication 334 requires an attached computation for any exclusion. We did not find guidance in Publication 334 or 525 on how an excluded recovery interacts with self-employment tax, so confirm with a CPA or EA.

What if the refunded expense was only partly business, like a phone bill?

You can only recover what you deducted. If you deducted 70% of a bill and get a $100 credit on it, the recovery to consider is $70. Publication 525's itemized-recoveries discussion limits the included amount to the smaller of the amount deducted or the amount recovered. If instead the carrier applies the amount as a credit on a later bill, it lowers what you pay for that service, so figure that year's phone deduction on what you actually paid and do not also report the credit on line 6. Keep the bill and the credit notice, and ask a CPA or EA if the split is unclear.

Does this rule apply to equipment I depreciated or expensed under section 179?

No, not directly. Publication 334 says the recovery rule does not apply to depreciation, which is recovered through the recapture rules, for example when business use of listed property falls to 50% or less. A rebate or return of an asset you already depreciated or expensed raises basis and recapture questions this article does not cover, so ask a CPA or EA.
