Filing and paying US taxes from abroad: e-file, post, payment and refunds

Most expat tax content stops at the point where the numbers are right. That is not where the difficulty is. The difficulty is that you are holding a finished return in a country where the software wants a US mobile number, the payment page wants a US routing number, and the refund box wants an account the bank closed when you left.

Can you e-file from abroad?

Yes in principle. Nothing in US law bars electronic filing from outside the country, and a foreign address is a supported address on a US return. What actually stops people is the identity and payment plumbing built around the filing: verification codes sent to US mobile numbers, address validators that reject non-US formats, and payment steps that assume a US bank.

Two categories have no e-file route regardless of software. A Streamlined Foreign Offshore package is submitted on paper to a designated address, with its certification signed by hand. And the FBAR is never part of the return at all: it is filed separately with FinCEN through the BSA E-Filing System, on its own schedule, whatever you do with the 1040.

Posting a return from another country

A paper return filed from abroad goes to a different IRS address from a domestic one, and the correct address depends on whether you are enclosing a payment. The IRS publishes the addresses for filers in a foreign country; using the domestic address delays processing rather than invalidating the return.

• Use the address the IRS publishes for taxpayers filing from a foreign country, and check it for the current year rather than reusing an old one.
• Keep proof of sending. A tracked international service gives you a date and a delivery record, which is the only evidence you will ever have.
• Sign everything by hand where a signature is required, and post originals where originals are required.
• Send the FBAR separately through FinCEN, and do not enclose it with the return.

Paying the IRS without a US bank account

This is the question with the least published guidance and the most anxiety attached. The IRS does accept payments from taxpayers without a US bank account, and publishes the routes for foreign electronic payments — including an international wire process with its own worksheet and identifying information. Card payments through the IRS's authorised processors are also available and carry a fee.

Whichever route you take, allow for the timing. An international transfer that leaves your account before the deadline may not be credited by it, and interest on an underpayment runs from the original due date regardless of the extended filing date an expat is entitled to.

Getting a refund abroad

Direct deposit generally requires a US bank account: the deposit fields expect a US routing number, and a foreign IBAN is not a substitute. Without one, the practical outcome is a paper cheque posted to the address on the return — which then has to be deposited by a foreign bank willing to take a US dollar cheque, often slowly and for a fee.

This is worth knowing before you file, because it changes the calculus for expats with a refundable credit: a refund you cannot practically bank is not the same as cash.

What Atamatax does and does not do here

Atamatax computes the return and generates the completed package — the forms, the schedules, and the workpapers behind them — for you or your accountant to file. It does not e-file, does not transmit anything to the IRS, does not submit the FBAR to FinCEN, and cannot produce an IRS acceptance acknowledgement, because it never sends anything to be acknowledged. The supported-forms page states this per form rather than in the abstract.

The order to do it in

1. Finish the return and confirm which of its components are filed with the IRS and which are filed separately.
2. Decide the filing route: electronic where available, paper where the situation requires it.
3. If paying, choose the payment route before the deadline and allow for international transfer time.
4. If posting, use the IRS's foreign-filer address for the current year and send it tracked.
5. File the FBAR separately through FinCEN's BSA E-Filing System.
6. Keep the proof — posting receipt, wire confirmation, FinCEN submission acknowledgement — because it is the only record that exists.
