Where do I send my W-8BEN, and does it go to the IRS?

Where does a W-8BEN go?

A W-8BEN goes to the person or company paying you, called the withholding agent, not to the IRS. You complete it, sign it and give it to the payer when they request it, before income is paid or credited. The payer relies on it to decide how to treat your payment.

The IRS says this on its own page about Form W-8BEN: foreign individuals who are beneficial owners of amounts subject to withholding give the form to the withholding agent or payer when requested. Entities use the separate Form W-8BEN-E, which also goes to the payer.

Who is the payer for a SourceX reward?

For a partner reward, the payer is the party that sends you the reward under your partner agreement. The agreement and the program terms say who that is and how the form is collected. Follow those instructions rather than guessing an address from a template or a forum post.

Two practical points follow:

• You do not need to find a mailing address or an IRS office. If a request points you there, treat it with suspicion.
• A reward becomes payable only after the buyer pays and SourceX receives its fee, so a request for your form is more likely to come near payment than at sign-up. Check the terms for the exact timing.

How should you send a tax form safely?

Treat a W-8BEN as sensitive. It carries your name, address, country of residence and often a tax identification number. A sensible sequence:

1. Confirm the request came through the partner portal, the signed agreement or an address you already verified.
2. Complete the form fully and sign it. An unsigned or incomplete form is likely to be sent back.
3. Upload it through the portal if one is offered. If email is the only option, protect the file with a password and send the password by a separate channel.
4. Keep a copy and the date you sent it.
5. Diarise a refresh date for when your details change or the form expires. Ask your tax adviser how long a form stays valid for your situation.

What will a legitimate payer ask, and not ask?

If a message looks wrong, go to the portal or contact SourceX through the details in the terms, not through the message.

What happens if the form is missing?

The payer may be unable to treat you as a foreign person with the correct documentation, and withholding rules can then bite. The mechanics are covered in what happens if you do not provide a W-8BEN. For the full set of items to prepare, see the paperwork checklist for your first international payout.

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

What if you are a firm or based in a specific country?

Firms use W-8BEN-E, which has more sections; start with the walkthrough on filling out a W-8BEN-E for an advisory or consulting firm. Country-specific points such as local tax registration are in guides like referring US companies from the UK. Whether you may join from your country at all is answered in can non-US residents join a US referral program.

How do rewards fit in?

Partners earn 25% of the eligible platform fees SourceX actually collects, capped at $100,000 per referred company, payable only after the buyer pays and SourceX receives its fee. No reward is guaranteed. The referral earnings calculator shows the formula.

Next step

Read the terms, then register as a partner. Keep your W-8BEN ready, but send it only when the payer asks.
