The Steamworks tax interview for non-US developers, explained

You have a build, a store page, and a bank account, and then Steamworks asks you to complete a tax interview. Suddenly you are answering questions about US tax residency, treaty articles, and identification numbers you have never heard of, in a form that does not explain why any of it applies to a person who has never set foot in the United States.

A lot of first-time developers stop here for weeks. The form looks like something you can only get one shot at, and getting it wrong feels expensive. It is neither: the interview can be retaken, and understanding what it is doing makes most of the questions straightforward.

This article explains the structure — what the interview is for, which document it produces, and the points where people most commonly stall. It is not tax advice and contains no figures, rates, or amounts, deliberately. Rules change, they differ by country and by circumstance, and the only correct final check is the current official guidance plus a qualified tax professional where you live.

Why a US tax form stands between you and your money

The company paying you is based in the United States. When a US business pays certain kinds of income to a person or company outside the US, US law generally requires that business to either withhold tax from the payment or hold documentation on file showing that a lower rate applies. That obligation sits with the payer, not with you, which is why it appears as a condition of getting paid rather than as something you could file later.

The tax interview is how that documentation gets collected. You are not filing a US tax return, and you are not being assessed on anything. You are telling the payer who you are, where you are tax resident, and whether an agreement between your country and the US changes how the payment should be treated.

Nothing in this interview settles what you owe in your own country. That is a separate question, handled by your own tax authority on your own timetable, and the last section of this article touches on it.

Which form the interview is trying to produce

The interview is a guided questionnaire whose output is one of a small number of US tax forms. You will usually never see a blank form; you answer questions and the correct one is generated and signed electronically at the end.

Which one you get depends on two branches. The first is whether you are a US person, which for almost every reader of this article is no. The second is whether you are answering as an individual or as a company.

• A US person, individual or entity, produces the domestic form used to certify a US taxpayer identification number
• A non-US individual produces Form W-8BEN — the certificate of foreign status for individuals
• A non-US entity produces Form W-8BEN-E, which is substantially longer and asks additional questions about what kind of entity you are

Individual or entity: decide this before you start

The individual-versus-entity branch changes the whole rest of the interview, so it is worth being deliberate about rather than clicking through.

A sole trader operating under a business or studio name is, in most countries, still an individual for this purpose. The name that goes on the form is generally the individual's legal name, with the trading name handled separately if the form asks for it at all. Registering a business name in your own country does not by itself create an entity in the sense this form means.

An incorporated company is an entity and takes the longer form, which asks about entity classification and, for treaty claims, about eligibility conditions that do not apply to individuals. If you incorporated recently, or you are unsure which side of the line your structure falls on, this is one of the specific points worth confirming with an accountant before you answer, because correcting it later means redoing the interview and possibly reissuing documentation.

Treaty benefits and the identification number question

Many countries have an income tax treaty with the United States. Where one exists, it can change how much US tax is withheld on the relevant category of income — potentially a great deal. The critical thing to understand is that eligibility is not automatic in effect. If you do not claim the treaty on the form, the treaty does not help you; the payer withholds at the default rate because the documentation on file does not say otherwise.

Claiming it requires two things. The first is stating your country of tax residence, which must be consistent with the address you have given. The second is a taxpayer identification number. For many years a US-issued number was effectively required for this, which was a real obstacle for individuals abroad; the forms now generally accept a tax identification number issued by your own country of residence instead. Which number that is for you, and whether your situation qualifies, is exactly the kind of detail that changes over time — check the current official instructions for the form rather than a forum post from several years ago.

The form also asks you to identify the treaty article and rate that apply to your income. That depends on how the income is categorised, which for storefront revenue is not always obvious to a non-specialist, and it is the single question in the interview most worth asking a professional about if anything here feels uncertain. This article deliberately does not tell you which category or rate applies to you, because that answer depends on your country, your structure, and the current treaty text.

What to have in front of you before you start

Most of the stalling happens because someone starts the interview without the information it will ask for and abandons it halfway. Gather this first and the whole thing takes a single sitting.

Before starting the tax interview:

- Legal name, spelled exactly as on official identification, in Latin script
- Permanent residence address - your actual country of tax residence,
  not a mailing address, not a PO box, not a c/o address
- Date of birth
- Your country's taxpayer identification number (or the US one, if you
  hold it)
- Your decision on individual vs entity, and the entity type if applicable
- Country of tax residence for the treaty section
- Bank details for payout: account holder name matching the above,
  bank name and address, SWIFT/BIC, account or IBAN, and any
  intermediary bank details your bank requires

Where people get stuck

The failures below are mundane and account for most of the time developers lose here. None of them are conceptually hard; they are just easy to get slightly wrong in a way the form does not immediately flag.

• Name mismatch — the name on the tax form, on the Steamworks account, and on the receiving bank account all need to line up. A payout can be held up by a discrepancy that looks trivial to a human
• Transliteration drift — if your name is not natively written in Latin script, pick one spelling and use it everywhere, including the bank
• Permanent residence versus mailing address — these are different fields with different meanings, and using a forwarding or care-of address in the permanent residence field can undermine a treaty claim
• Address formatting — the form expects a structure that may not match how addresses are written in your country. Put the parts in the fields they are asked for rather than reproducing your local ordering
• The certification and signature — the typed signature generally has to match the name on the form exactly, and there is usually a declaration about capacity to sign that is easy to click past
• Expiry — these certificates are valid for a limited period and then have to be redone. Steamworks will warn you, but the warning tends to arrive at an inconvenient moment. Treat the expiry as a calendar item
• Changes of circumstance — moving country, changing your name, or incorporating means the form on file is no longer accurate and the interview needs redoing
• Payout thresholds and timing — there is a minimum balance before a payment is issued and a payment cycle it follows. The first payment usually takes longer to arrive than people expect, and that is normally the process working rather than a problem

It is not a one-shot document

The single most useful thing to know is that you can retake the interview. It is not a filing you submit once and live with. If you realise you selected the wrong entity type, mistyped an address, or answered the treaty section without understanding it, go back and do it again.

That removes most of the reason people freeze on it. Answer carefully, check the fields that identify you against your actual documents, and if something in the treaty section is genuinely unclear, complete the interview conservatively and revisit it after you have had advice, rather than leaving your account unable to pay you at all.

After the money arrives: your own country's side

The US interview handles one narrow question. Everything about how this income is treated where you live is separate and starts once money actually moves.

The topics that typically come up are the same in most countries, even though the answers differ: how the income is classified for your own return, which exchange rate and which date you convert at, whether you need to register as a business, how any tax withheld abroad is handled — most countries have a foreign tax credit mechanism intended to prevent the same income being taxed twice, but claiming it usually requires documentation you should keep from the start — and how cross-border sales of digital goods interact with your country's consumption tax or VAT rules, which tends to be the least intuitive part.

Two practical habits make all of this cheaper. Keep the payment statements and any withholding documentation from the very first payout, in one place, rather than reconstructing them a year later. And talk to a tax professional once, early, ideally before your first payment rather than after your first filing deadline. A single consultation is inexpensive compared with the cost of unwinding a year filed on a wrong assumption.

To restate the caveat this article opened with: everything above describes how the process is structured, not what you owe. No rate, threshold, category, or eligibility statement here should be relied on for your own situation. Confirm the details against the current official instructions from the US tax authority and the Steamworks documentation, and have a qualified professional in your country check your specific case.
