How to Pay US Tax From Abroad in 2026

Nobody tells you until you are standing in front of a payment screen that almost every way of paying the Internal Revenue Service assumes you already have a US bank account. Direct Pay wants a US routing number. EFTPS wanted a US bank account too, and is on its way out. The card processors work, but the IRS does not publish whether they will take a card issued outside the United States. You can end up with a correctly filed return, a known balance, and no obvious way to settle it.

The second trap is older guidance. A great deal of advice written for Americans abroad still says "enrol in EFTPS." That advice is dead. EFTPS has been closed to new individual enrolments since 17 October 2025, and the IRS has said it will be sunset for individuals later in 2026. A page recommending it without mentioning that has not been touched in over a year.

This guide covers the one method built for a foreign bank account — the international wire through the Federal Tax Collection Service — in enough detail to hand to your bank, plus what Direct Pay and the card processors will and will not do, the estimated tax dates for tax year 2026, and what it costs if you get the timing wrong. Returns filed in early 2026 are tax year 2025 returns, and every figure below is labelled.

Who this guide is for

• US citizens abroad with no US bank account and a balance due
• Accidental Americans settling a bill for the first time
• Freelancers abroad making quarterly estimated payments
• Anyone whose only card was issued outside the United States
• People told to use EFTPS who found enrolment closed
• Filers relying on the automatic two-month extension and unsure about interest

Quick answer

All payments to the Internal Revenue Service must be in US dollars. With a foreign bank account, your route is the international wire through the Federal Tax Collection Service: complete the Same-Day Taxpayer Payment Worksheet, then instruct your bank to wire to IRS account 20092900IRS at routing number 091036164 (US TREAS SINGLE TX). Your bank must have a banking relationship with a US bank, need not be an affiliate, and will charge its own wire fee — the IRS warns this "can be costly." IRS Direct Pay is free and needs no sign-in but requires a US routing number. EFTPS is closed to new individual enrolments after 17 October 2025 and is being sunset during 2026, so ignore any guide recommending it. Cards are the practical no-US-bank route: Pay1040 charges US$2.15 for debit, 1.75% for consumer credit with a US$2.50 minimum and 2.89% commercial; ACI Payments charges US$2.10, 1.85% with a US$2.50 minimum, and 2.95%. Whether the processors accept foreign-issued cards is not stated by the IRS. Estimated tax for tax year 2026 is due 15 April 2026, 15 June 2026, 15 September 2026 and 15 January 2027. Pay late and the failure-to-pay penalty is 0.5% a month to a 25% cap, with interest at 7% for the fourth quarter of 2026.

The core problem: the rails assume a US bank account

Think of the IRS payment options as two groups. One pulls money out of a bank account you nominate. The other pushes money in from somewhere else.

The pull methods — Direct Pay, EFTPS, direct debit arranged with a return — all need an account number and routing number in the US format. A routing number is nine digits. An IBAN is not a routing number and neither is a sort code. This is less an IRS policy choice than a limitation of the domestic clearing system those methods ride on.

The push methods are the international wire and the card processors. Both move money towards the Treasury from outside, and both cost something. That is the real decision abroad: a wire fee set by your own bank, or a processor fee set as a percentage of what you owe.

One more constraint applies to everything. Payments must be in US dollars. Your bank handles the conversion at its own rate, with its own spread. That spread is frequently larger than the headline fee, and nobody itemises it for you.

The international wire: Federal Tax Collection Service

This is the method the IRS built for exactly this situation and the one to use for a large balance. It is described on the IRS foreign electronic payments page, and there is a specific sequence.

Step one: the Same-Day Taxpayer Payment Worksheet

Complete the Same-Day Taxpayer Payment Worksheet before you contact your bank. It captures your taxpayer identification number, the tax type, the tax period and the amount, in the format the Treasury's system expects. It is not an IRS submission — you hand the details to your bank, which uses them to build the wire message. Get the tax type or period wrong and the money lands against the wrong year, a slower problem to fix than simply paying late.

Step two: the account and routing details

The wire goes to IRS account 20092900IRS, at routing number (RTN/ABA) 091036164, which belongs to US TREAS SINGLE TX. Give those exactly as written, including the letters in the account number, which some foreign bank staff will assume is a typing error.

Step three: check that your bank can actually do it

Here is the condition most people miss. Your foreign bank must have a banking relationship with a US bank. It need not be an affiliate or a branch — a correspondent relationship is enough — but without one the wire cannot be routed. Ask before you set the payment up.

If your bank is unsure, the IRS runs a foreign bank help line on 314-425-1810, which exists for bank staff as much as for taxpayers.

Step four: accept that it costs money

Your bank's wire fee applies, and the IRS states plainly that it "can be costly." That is the agency's own language. The fee is set by your bank, not the Treasury, so there is nothing to negotiate on the IRS side.

The wire is still usually right for a large balance, because the fee is flat rather than a percentage. On a US$20,000 balance, a wire fee of even US$50 is a quarter of one percent. A consumer credit card at 1.75% is US$350.

IRS Direct Pay, and why it will not work for you

Direct Pay is genuinely good: free, no sign-in, and you can change or cancel a payment within two days of scheduling it. For anyone with a US bank account nothing beats it.

It requires a US routing number. The IRS lists Direct Pay under "other U.S. based payment methods", the clearest possible signal about its intended audience. If you have kept a US checking account open — a credit union account from your student years, a joint account with family — Direct Pay is the cheapest method available and worth the maintenance on its own. If you have not, it is not an option, and no amount of persistence at the entry screen changes that.

EFTPS: why older guidance is now wrong

The Electronic Federal Tax Payment System has been the standard recommendation for Americans abroad for years. It is now going away for individuals.

No new individual enrolments have been accepted since 17 October 2025. The IRS has said EFTPS "will be sunset for individuals later in 2026." Businesses are a separate question, but for an individual it is not a route you can newly take up, nor one to build a habit around if you somehow still have access.

This matters beyond EFTPS itself, because it is a reliable test of how current a piece of guidance is. Any page that lists EFTPS as the way to pay from abroad without noting the closure is stale. Treat the rest of its figures with the same suspicion.

A related change in the same direction: paper cheques and money orders are still accepted "for now" but are being phased down under Executive Order 14247, and the IRS generally stopped issuing paper refund cheques to individuals after 30 September 2025.

Debit and credit cards: the practical route with no US bank

With no US bank account and no appetite for a wire, cards are what remain. The IRS does not process cards itself; it authorises third-party processors who charge a fee on top of the tax. These were the fees on the IRS "pay by debit or credit card" page as reviewed on 24 September 2026.

Read that table as two products. A debit card is a flat fee — US$2.10 or US$2.15 regardless of amount, extraordinarily cheap on a large balance if you can fund it. A credit card is a percentage that scales with what you owe. Commercial rates are higher again, so paying personal tax on a business card is the most expensive option on the page.

The honest gap: the IRS does not state whether foreign-issued cards are accepted. There is no published answer either way, so this guide will not invent one. Plenty of people abroad report success and plenty report declines; neither is an official position. If your only card was issued outside the United States, test it with a small payment well ahead of the deadline and keep the wire ready as a fallback. Do not discover the answer at 11pm on 15 April.

Estimated tax: the four dates and the safe harbour

If you are self-employed abroad, nobody is withholding tax for you, which means quarterly payments and four more occasions to solve the payment problem. These are the tax year 2026 estimated tax due dates.

The fourth falls in the following calendar year, and the second shares its date with the automatic extension for filers abroad, which trips people into thinking one covers the other. It does not.

The safe harbour decides whether you are required to pay estimated tax at all. You are, if you expect to owe US$1,000 or more and your withholding is less than the smaller of 90% of your current-year tax or 100% of your prior-year tax. That second test rises to 110% if your prior-year adjusted gross income was over US$150,000, or US$75,000 married filing separately.

The prior-year figure is the one to use in practice, because it is a number you already know — the only test you can satisfy with certainty before the year has finished. Paying 100% of last year's tax in four instalments, or 110% above the income threshold, keeps you inside the harbour even if this year turns out far better than expected.

What it costs you to get this wrong

Two separate charges, plus interest, and they behave differently.

Failure to pay is 0.5% of the unpaid tax per month or part month, capped at 25%. It falls to 0.25% a month under an approved installment agreement and rises to 1% a month after a notice of intent to levy. That first rate is the reason to ask for an agreement even if you intend to clear the balance quickly.

Failure to file is far worse: 5% of unpaid tax per month or part month, capped at 25%, with a minimum for returns more than 60 days late of the lesser of 100% of the underpayment or US$525 for returns due after 31 December 2025. When both run, the failure-to-file penalty is reduced by the failure-to-pay penalty — 5% a month for five months, then 0.5% a month alone.

Failure to file costs ten times failure to pay, per month. File on time even if you cannot pay.

Interest runs on top of both, at 7% on individual underpayments for the fourth quarter of 2026, set by Rev. Rul. 2026-15 effective 1 October 2026 and unchanged from the third quarter. Interest is not a penalty and is not waived for reasonable cause in the way penalties sometimes are.

And the timing trap specific to filers abroad: the automatic two-month extension to 15 June 2026 for the tax year 2025 return is real, requires no form, and needs only a statement attached. Late-payment penalties run from 15 June if you qualify. But interest accrues from 15 April regardless. Filing Form 4868 by 15 June extends filing to 15 October 2026 — time to file, not time to pay. You may also see references to a further discretionary extension to 15 December; no official confirmation of it is published, so do not plan around it.

How to pay from abroad, step by step

1. Work out the amount and the tax year first. A payment applied to the wrong period creates a correspondence problem that outlasts the debt.
2. Check whether you have, or can reopen, a US bank account. If yes, use Direct Pay and stop here.
3. For a large balance, go to the wire. Complete the Same-Day Taxpayer Payment Worksheet first.
4. Confirm your bank has a US banking relationship. A correspondent relationship is enough. If they are unsure, point them at 314-425-1810.
5. Instruct the wire to IRS account 20092900IRS, RTN 091036164, US TREAS SINGLE TX, in US dollars, and ask your bank for the fee in advance.
6. For a small balance, compare the card fees — US$2.15 or US$2.10 flat on debit against 1.75% or 1.85% on consumer credit.
7. If your card was issued outside the United States, test it early, because acceptance is not published.
8. Keep the confirmation. Wire reference, processor receipt or Direct Pay confirmation number is your evidence of the payment date.

Mistakes that cost money

Following guidance that tells you to enrol in EFTPS. Closed to new individual enrolments after 17 October 2025 and being sunset during 2026. Its presence in a guide tells you the guide is out of date.

Assuming the automatic extension to 15 June stops interest. It does not. Interest runs from 15 April at 7% for the fourth quarter of 2026, whatever extension you qualify for.

Paying a large balance on a consumer credit card. At 1.75% or 1.85%, a US$20,000 bill costs US$350 to US$370. A debit card is a flat US$2.10 or US$2.15.

Wiring without the worksheet. The Same-Day Taxpayer Payment Worksheet exists so the tax type and period travel with the money. Skip it and the payment may land against the wrong year.

Not checking the US banking relationship first. Your bank needs one for the wire to route. Find out before the deadline, not during it.

Paying nothing because you cannot pay everything. Failure to pay is 0.5% a month. Failure to file is 5% a month with a US$525 floor. Always file.

Forgetting the currency conversion spread. Payments must be in US dollars and your bank sets the rate. The spread is often larger than the fee you were comparing.

Edge cases worth knowing

An installment agreement halves the penalty rate. Approved agreements carry 0.25% a month rather than 0.5%. If the balance will take months to clear, it pays for itself.

A notice of intent to levy doubles it. After that notice, failure to pay runs at 1% a month.

Prior-year safe harbour is the one you can actually hit. 100% of last year's tax, or 110% if prior-year adjusted gross income exceeded US$150,000, is knowable in advance in a way that 90% of this year's tax is not.

Keeping one US account open is a legitimate strategy. Direct Pay is free and the wire is not. A US checking account maintained from abroad removes the problem this entire guide describes.

Disclaimer

This guide describes federal tax payment methods, fees, penalties and interest rates published by the Internal Revenue Service and labelled by the period they apply to. It is information, not tax advice. Processor fees and interest rates change — the card fees here were on the IRS page reviewed 24 September 2026 and the 7% rate applies to the fourth quarter of 2026. Whether foreign-issued cards are accepted is not published by the IRS and is not asserted here. Your own bank's wire fees and exchange rates are its business, not the Treasury's, and you should confirm both before instructing a payment.

The short version

If you have a US bank account, use Direct Pay. It is free, needs no sign-in, and you can cancel within two days. Everything else here is for people who do not have one.

With a foreign bank account, the method built for you is the international wire through the Federal Tax Collection Service: Same-Day Taxpayer Payment Worksheet first, then IRS account 20092900IRS at routing number 091036164, US TREAS SINGLE TX, in US dollars, through a bank that has a US banking relationship. It costs whatever your bank charges, and the IRS says that can be costly. For smaller amounts, a debit card at a flat US$2.15 with Pay1040 or US$2.10 with ACI Payments beats a consumer credit card at 1.75% or 1.85% by a wide margin — though whether a foreign-issued card is accepted is something the IRS has never put in writing, so test it early.

Ignore anything that tells you to use EFTPS. And whatever you do, file on time: failure to pay runs at 0.5% a month to a 25% cap, failure to file at 5% a month with a US$525 minimum for returns due after 31 December 2025, and interest at 7% from 15 April no matter which extension you qualify for.
