Executive Summary

Quick Answer: Yes — payment processing fees are tax-deductible for your small business.

For small merchants, every dollar counts. The good news is that the credit card fees, transaction charges, and merchant service fees your business pays to accept payments are fully deductible as ordinary and necessary business expenses under IRS rules. That means the processing fees eating into your margins can help reduce your taxable income at tax time.

What Are Payment Processing Fees?

Payment processing fees are the charges your business pays to accept electronic payments from customers. Every time someone swipes, taps, or types in their card number, a slice of that transaction goes to the various parties that made it possible. For a small merchant, these fees typically show up on your monthly merchant statement and can range from less than 1% to 3.5% or more of each transaction depending on card type and how the payment is taken.

Here’s a breakdown of the fees that make up what you pay:

• Interchange Fees: Set by Visa, Mastercard, and other card networks, interchange is the largest piece of the pie. It goes to the bank that issued your customer’s card and is non-negotiable.
• Assessment Fees: These smaller fees go directly to the card networks (Visa, Mastercard, Discover, Amex). Also non-negotiable.
• Processor Markup: This is what your payment processor adds to your payment. Unlike interchange, this portion is often negotiable — and it’s where working with a transparent processor like IntelliPay can make a real difference.
• Additional Fees: Depending on your setup, you may also see charges for gateway access, PCI compliance, chargebacks, or monthly account maintenance. All of these count.

The mix of these fees depends on whether you’re taking in-person payments, processing online orders, or running card-not-present transactions — and whether your customers are using debit, credit, or rewards cards.

Are Payment Processing Fees Tax-Deductible? (The Short Answer: Yes)

In the United States, payment processing fees are generally considered ordinary and necessary business expenses, which is exactly what the IRS requires for a deduction. That means the fees you pay to accept credit and debit cards, process ACH payments, or use a payment gateway can all reduce your taxable income.

The IRS’s standard for deductible business expenses requires that they be both:

• Ordinary: Common and accepted in your type of business. For any merchant accepting card payments today, processing fees clearly qualify.
• Necessary: Helpful and appropriate for your business operations. You can’t serve your customers without the ability to accept payment, enough said.

Because accepting card payments is standard operating procedure for virtually every small merchant, processing fees comfortably meet both tests.

Where IRS Guidance Comes From in 2025

You may have seen references to IRS Publication 535 (Business Expenses) online. Here’s an important update: the IRS announced in January 2024 that Publication 535 will no longer be revised. The 2022 edition remains the last published version. For 2025 tax guidance, the IRS now directs small business owners to IRS Publication 334 (Tax Guide for Small Business) and the current Schedule C (Form 1040) instructions, both of which confirm that ordinary and necessary business expenses — including payment processing fees remain fully deductible.

Transaction Fees and Merchant Fees: What’s Deductible?

Good news: it’s pretty comprehensive. Here’s a practical rundown for small merchants:

• Per-transaction fees: Fees charged per sale are deductible. These are ordinary, recurring costs directly tied to generating revenue.
• Merchant account fees: Monthly or annual account fees from your merchant services provider qualify.
• Payment gateway fees: If you pay for a gateway to process online payments, those costs are deductible.
• PCI compliance fees: These are the cost of doing business securely. Deductible.
• Chargeback fees: Fees your processor charges when a customer disputes a transaction are also deductible.
• ACH/eCheck processing fees: Fees for electronic check processing follow the same rules and are deductible.

The key rule: only deduct fees tied to your business, not personal transactions. If you use the same payment account for personal and business purchases (not recommended!), you’ll need to separate them carefully.

Your 1099-K and Processing Fees — How They Connect

Your payment processor must issue a Form 1099-K by January 31st each year if you meet the reporting threshold. This form shows your gross card transaction volume — before processing fees are subtracted. That’s important: your 1099-K will show a higher number than what actually landed in your bank account. You report the gross amount as income and then deduct your processing fees as a business expense, which brings your taxable income down to what you actually kept.

Where to Report Processing Fees on Your 2025 Tax Return

Where these fees go on your return depends on your business structure:

• Sole Proprietors & Single-Member LLCs: Report on Schedule C (Form 1040). Processing fees typically go on Line 17 (Legal and Professional Services) or as an “Other Expense” on Line 48. Some tax professionals categorize them under “Bank Charges” or a similar line. Ask your tax preparer which line they prefer — the category matters less than making sure it’s on there.
• Partnerships (Multi-Member LLCs): Report on Form 1065.
• S-Corporations: Report on Form 1120-S.
• C-Corporations: Report on Form 1120.

Not sure how to classify your fees? Your monthly merchant statement is your friend. It breaks down exactly what you paid, which makes your tax preparer’s job much easier.

What’s New for 2025 That Small Merchants Should Know

Tax law doesn’t stand still, and 2025 brings a few changes worth being aware of:

• No tax on qualified tips (new for 2025): Starting in 2025, certain tip income may be deductible or excluded from taxable income. If your business collects tips through your payment system, this is worth a conversation with your tax pro — the deduction is claimed on Schedule 1-A, not Schedule C.
• IRS Publication 535 is no longer updated: As noted above, the 2022 edition is the last. Rely on IRS Publication 334 and the 2025 Schedule C instructions for current guidance.
• 1099-K reporting thresholds: For reportable payments made after 2025, the information reporting threshold increases to $2,000. Check IRS.gov for the current threshold applicable to your 2025 return, as these rules have been in transition.
• QBI deduction made permanent: The 20% qualified business income (QBI) deduction for pass-through entities, previously set to expire, has been made permanent. This isn’t specific to processing fees, but it’s great news for sole proprietors and small LLC owners, reducing their overall tax bill.
• 100% bonus depreciation restored: For certain qualified property acquired after January 19, 2025, 100% first-year depreciation is available again. If you’re buying new point-of-sale hardware, this matters.

As always, consult a qualified tax professional to confirm how these changes apply to your specific situation.

Best Practices for Deducting Payment Processing Fees

Getting the deduction is one thing. Being able to defend it if the IRS ever asks questions is another. Here’s how to stay clean and capture every dollar you’re owed:

1. Keep your monthly merchant statements. Your processor’s monthly statement is your primary documentation. It shows exactly what fees you paid and when. Download and save these as PDFs every month. If IntelliPay is your processor, your statements are available directly in your account portal.
2. Keep your personal and business finances separate. Run your business through a dedicated business bank account and merchant account. It makes deductions cleaner and dramatically reduces your audit risk.
3. Reconcile your 1099-K against your bank deposits. Your gross card volume on the 1099-K won’t match what hit your bank account. The difference is largely your processing fees. Document this reconciliation so your reported income and deductions line up.
4. Use accounting software or work with a bookkeeper. Categorizing fees throughout the year beats scrambling in April. Many small merchants find that having a bookkeeper pays for itself in deductions alone.
5. Work with a tax professional who knows small businesses. Payment processing fees are straightforward, but they touch your income reporting, your Schedule C, and sometimes your state return, too. A tax pro who works with merchants will know exactly where everything goes.
6. Stay current on IRS updates. Tax rules do change. Make a habit of checking IRS.gov/smallbiz at the start of each tax year.

Frequently Asked Questions

Are ALL payment processing fees deductible, or just some?

All legitimate payment processing fees tied to your business operations are deductible. This includes per-transaction fees, monthly account fees, gateway fees, PCI compliance fees, and even chargeback fees. The only fees you can’t deduct are personal transactions that got mixed into a business account — another reason to keep them separate.

What if I use a flat-rate payment setup? Can I still deduct fees?

Yes. Whether you’re on an interchange-plus pricing model or a flat-rate model, the fees you pay are still deductible business expenses. Your monthly statement or account dashboard will show you the total fees paid for the year.

My 1099-K shows more income than I actually deposited. Why?

Your 1099-K reports gross card transaction volume before processing fees are deducted. The processor takes their fees before depositing the remainder in your account. You report the gross amount on your return and then deduct the fees as a business expense. The net result is that you’re only taxed on what you actually kept — but you need to make sure both sides of that equation are on your return.

Can I deduct processing fees if I operate as a sole proprietor?

Absolutely. Sole proprietors report these fees on Schedule C (Form 1040). They go under Line 17 (Legal and Professional Services) or as an other expense on Line 48. Either way, they reduce your net business income — which lowers both your income tax and self-employment tax.

What records do I need to keep in case of an audit?

Your monthly merchant statements are the most important document. They show each fee, the date, and the amount. Back those up with your bank statements showing the deposits (net of fees). The IRS generally recommends keeping business records for at least three years from the date you filed the return — many CPAs suggest keeping them for seven years to be safe.

Does the type of card matter? Are rewards card fees still deductible?

Yes, rewards card processing fees are deductible just like any other card fees. In fact, premium rewards cards typically carry higher interchange rates, so you might be paying more in fees — but all of those fees are deductible. If you’re concerned about the cost of rewards card processing, that’s a conversation worth having about your pricing model.

What’s the deal with IRS Publication 535? I keep seeing it referenced online.

IRS Publication 535 (Business Expenses) was the go-to reference guide for years, but the IRS announced in early 2024 that it will no longer be updated. The 2022 edition is the final version. For 2025, look to IRS Publication 334 (Tax Guide for Small Business) and the 2025 Schedule C instructions at IRS.gov for current guidance. The core rules on ordinary and necessary expenses haven’t changed.

Can I deduct processing fees and also take the QBI deduction?

Yes — these are separate. Processing fees reduce your net business income on Schedule C. The qualified business income (QBI) deduction (now permanent for pass-through entities) is then calculated on that lower net income figure. So, deducting your processing fees actually increases the benefit you get from the QBI deduction, too. Talk to your tax professional about how to maximize both.

The Bottom Line for Small Merchants

Payment processing fees are a real cost of running your business — but they’re also a real tax deduction. The key is staying organized: save your monthly statements, keep business and personal finances separate, reconcile your 1099-K, and work with a tax professional who understands small businesses.

And if the fees themselves feel like too much of a burden, that’s worth looking at too. Transparent pricing, the right payment model for your volume, and a processor that doesn’t bury fees in fine print can make a meaningful difference in what you’re actually paying — whether it’s deductible or not.
