Are Payment Processing Fees Tax-Deductible for Businesses?

Payment processing fees are tax deductible for businesses. Every charge your processor takes out — the per-transaction cut from Stripe or Square, the monthly gateway subscription, the interchange baked into your merchant statement, even chargeback penalties — reduces your taxable income as an ordinary business expense.¹ The one condition is that the fees have to be tied to a trade or business, not personal transactions.

What Counts as a Processing Fee

The deduction covers more than the percentage-plus-flat-fee you see on each sale. It reaches the full set of costs a processor imposes to keep you accepting payments:

Per-transaction charges on each sale.
Interchange fees that flow between the merchant’s bank and the cardholder’s bank, which are built into your overall processing cost.
Monthly or annual platform, gateway, and software subscription fees from processors like Stripe, PayPal, or Square.
Chargeback fees when a customer disputes a transaction, deductible even though the underlying sale fell through.
PCI compliance and similar security-related charges required to maintain your ability to process cards.

You don’t have to break each one out. Most businesses group them into a single expense line.

The 1099-K Reconciliation That Trips People Up

Payment processors report your gross sales on Form 1099-K, meaning the total before any fees, refunds, or credits are subtracted.² If your 1099-K shows $100,000 in gross payments but only $97,000 actually hit your bank account because $3,000 went to fees, the IRS starts from the $100,000 figure. Skip the deduction and you pay tax on money you never received.

The IRS states that fees, credits, refunds, shipping costs, and discounts “are not taxable income” and that “you can deduct them from the gross amount.”² Pull your merchant statements, which break out fees separately, and reconcile them against the 1099-K figure. That gives you the exact deduction amount. For tax year 2026, third-party settlement organizations issue Form 1099-K when your gross payments exceed $20,000 across more than 200 transactions.³ Even if you fall below that threshold and get no form, the fees are still deductible against the income you report.

Where to Claim the Deduction

Sole Proprietors and Single-Member LLCs

Report the expense on Schedule C, filed with your Form 1040.⁴ Processing fees fit on Line 10, “Commissions and fees.”⁵ If you want to itemize them separately from other commission expenses, list them in Part V (Other Expenses) and carry the total to Line 27b.

Partnerships and Corporations

Partnerships use Line 21, “Other deductions,” on Form 1065, with an attached statement itemizing the expense.⁶ C-Corporations use Line 26, also “Other deductions,” on Form 1120.⁷ S-Corporations follow the same pattern on Form 1120-S. In each case processing fees typically ride along with other administrative costs on the deduction statement.

When the Deduction Hits Your Return

Timing follows your accounting method under the general rules for methods of accounting.⁸

On the cash method, you deduct the fee in the year you actually pay it. A December sale whose fee isn’t debited until January belongs on the following year’s return. Most small businesses use this method.
On the accrual method, you deduct the fee in the year the liability arises — the year the transaction happens — as long as the amount is determinable with reasonable accuracy. When the money leaves your account doesn’t matter.

You can’t bounce between methods to shift timing. Switching generally requires IRS approval.⁸

Prepaid Fees

Some processors give a discount if you prepay a year of service. Cash-method taxpayers can generally deduct a prepaid expense in the year of payment if the benefit doesn’t extend beyond 12 months after the date you first receive it, or the end of the following tax year, whichever comes first.⁹ A 12-month prepaid subscription paid in November 2026 qualifies. A multi-year contract does not — you’d spread the deduction across the years of service.

Terminals and Card Readers Follow a Different Path

If you buy a physical card reader or point-of-sale terminal, that’s a capital asset rather than a fee. The IRS treats purchased equipment as property you depreciate over time.¹⁰ In practice, Section 179 lets most small businesses deduct the entire purchase price in the year they buy the equipment instead of spreading it out.¹¹ Payment terminals sit well inside the Section 179 limits. Rent or lease a terminal instead, and the monthly payment is a straightforward operating expense in the period you pay it.

When Processing Fees Are Not Deductible

The deduction only reaches fees tied to a trade or business. Sell personal belongings through PayPal or Venmo and pay a platform fee? That’s not a business expense. Fees on personal transactions like splitting a bill through a payment app aren’t either.

Hobby activity gets similar treatment. If the IRS classifies what you’re doing as a hobby rather than a business, expenses from that activity — including processing fees — generally can’t be deducted against your other income.¹² The hobby loss rule caps deductions at the gross income the activity generates and subjects them to further limits. Occasional craft sales that haven’t turned a profit in most recent years are exactly the kind of activity the IRS may pull into that category.

Records to Keep

You need documentation for every deduction you claim. For processing fees, that means monthly merchant statements, processor dashboard reports, or bank statements showing the fee debits. Digital records are fine as long as they’re accurate, legible, and organized well enough to produce quickly.¹³

Hold the records at least three years from the date you file the return claiming the deduction. If you underreport income by more than 25% of gross income, the retention period stretches to six years.¹³ Six years is the safer default, since you rarely know in advance whether the IRS will flag a discrepancy.
