The IRS can now take card payments itself and pass the fee on

If your organisation has ever paid a federal tax bill by card, you went through a third-party processor and paid that processor's fee. The IRS itself couldn't take the card. On 19 October 2026 Treasury and the IRS published final regulations that change this. They amend section 301.6311-2 of the procedure and administration regulations (26 CFR part 301), and they took effect the same day: "These final regulations are effective on October 19, 2026."

This took a while. The proposed rule came out on 2 July 2024 (89 FR 54746), and the statutory change behind it is older still.

What the law said before

Section 6311 of the tax code has long let the government contract for card payment services. What it didn't allow was paying for them. The old text "prohibited the Secretary from paying any fee or other consideration under any such contract." So the IRS sent card payers off to outside processors, who charged the payer directly.

Section 2303 of the Taxpayer First Act (Public Law 116-25) added an exception. The Secretary may now pay a fee under those contracts, as long as the full amount is recovered from the people who pay by card. These regulations put that exception into the IRS's own rules. In the preamble's words, a taxpayer could pay by card "without having to separately wait for the IRS to connect them to third-party processors."

What the new rule says

The amended regulation makes four points that matter to a payer.

The Commissioner may enter into card payment contracts "if such contracts are cost beneficial to the government." If the IRS pays a fee under one, "it must recoup the full amount paid under such contracts as a reimbursement fee." The fee is capped at what the IRS actually pays: "The reimbursement fees will be limited to the amount of the fees that IRS pays under any such contract." And "the Commissioner will seek to minimize the amount of the fees paid."

Your finance team will want to know this part. "The reimbursement fee is not a tax imposed by the Code," and "no portion of the reimbursement fee is eligible for refund or credit under section 6402 of the Code." If you overpay a tax and get a refund, the card fee stays paid.

There's also a line for card issuers. Card dispute rights can be used for errors in the card transaction, "but not for the purpose of resolving any errors, disputes or adjustments relating to the underlying tax liability." A cardholder who thinks the tax itself was wrong takes that up with the IRS.

The new rules "apply to payments of taxes and reimbursement fees made on or after October 19, 2026."

What it doesn't do

The regulation lets the IRS accept cards directly. It doesn't say it has. The document gives no launch date for direct card acceptance, and it says the change "would allow the IRS to directly accept payments of tax by credit or debit card." Until the IRS says otherwise, the third-party processors you use today are still the route.

It also doesn't set a fee. The fee will equal whatever the IRS pays under its contracts, and the rule doesn't name a figure or a percentage.

Treasury and the IRS "received eight comments," mostly supportive. One commenter wanted no fee at all, and the agencies' answer was that the statute only gives the Secretary "the discretion to pay a fee" when it is fully recouped. A request for a federal contracting cost comparison was called "beyond the scope of these regulations."

Who it reaches

Anyone who pays federal tax by card, which includes businesses that put a tax bill on a corporate card for the rewards. For a bank or credit union, there are two angles. One is your own tax payments, if you ever pay by card. The other is your cardholders: once the IRS starts taking cards itself, your dispute team may see IRS charges with a separate reimbursement fee line, and they should know the fee can't be refunded through the tax system and the tax itself can't be disputed through the card.

What it could mean

We think this is a small rule with a slow fuse. Nothing changes for most payers until the IRS announces it is taking cards directly, and the regulation is silent on when that happens.

When it does, our guess is the fee will look a lot like today's processor fees, because it is a pass-through of what the IRS pays a processor. What changes is who you deal with. A card payment to the IRS would go to the IRS, with no outside site in the middle, and we'd expect fewer "which processor did we use?" questions at year end.

For card issuers, it's worth a note in the dispute procedures now. The line between a card error and a tax disagreement is easy to blur when a member calls upset about a charge, and the regulation draws that line clearly. Briefing the team costs little, and it's easier before the calls start.

If your organisation pays tax by card for rewards, check whether that still makes sense once the fee is the IRS's own and can never come back as part of a refund.
