Why do I need to fill out a W-9 for a referral program?

Why a referral program asks for a W-9

The short answer: the IRS form instructions say Form W-9 is used to give a correct taxpayer identification number (TIN) to a person who is required to file an information return reporting amounts paid to you. See the IRS page About Form W-9. A program that pays referral rewards to US partners may need to report those payments, so it collects the TIN first.

This is general information, not legal, tax or financial advice. Confirm with your own tax adviser how your referral income is treated.

What a W-9 is and is not

The IRS publishes current rules for when a business must file Form 1099-NEC for payments to non-employees in its instructions for Forms 1099-MISC and 1099-NEC. Reporting thresholds change, so read the current instructions or ask a tax adviser rather than relying on an old figure.

What the form asks for

The form is short. In general you provide:

1. Your name as shown on your tax return, and a business name if different.
2. Your federal tax classification, such as individual or sole proprietor, or a type of entity.
3. Your address.
4. Your TIN: a Social Security number for individuals or an employer identification number for many entities.
5. Your signature and date certifying the information is correct.

Match the name line to the tax classification and TIN. A sole proprietor with an EIN typically uses their own name on the name line and may add a business name on the second line; an LLC or corporation follows the form's instructions for its classification. Mismatches are a common reason for payment delays, so read the instructions on the form.

Is it safe to give a W-9?

A W-9 contains sensitive identifiers, so treat it that way. Send it only through a channel the payer designates, not by open email, and only to the party that will actually pay you. The payer is generally expected to keep it on file and not file it with the IRS. If a request arrives out of the blue from an unfamiliar sender, verify it through a known contact before responding.

Where this fits in the SourceX partner flow

Partners make introductions and are paid only after a deal completes. Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. The reward is paid only after the buyer pays and SourceX receives its fee; an introduction, meeting or signed agreement alone does not trigger payment, and no reward is guaranteed. Nothing in the referral steps requires a tax form to make an introduction; what documentation is needed before a payment is set by the signed partner agreement and the published terms. The what does paid on collection mean page explains why payment follows collection, and the what is a referral program page covers the basics. Terms for partners are in the program terms.

Partners outside the United States

Non-US payees generally give a different form. The IRS explains in About Form W-8BEN that foreign individuals who are beneficial owners of certain payments give that form to the payer, while US persons use Form W-9. Which one applies to you depends on your status, so confirm with a tax adviser in your own country as well as the payer.

Checklist before you fill one out

• I know whether I am a US person for tax purposes.
• My name matches my tax return and my TIN.
• I have chosen the right tax classification for me or my entity.
• I am sending it through the payer's designated channel.
• I have asked my tax adviser whether this income needs any other steps.

Licensed professionals, such as CPAs, attorneys and registered representatives, should also check their own rules on referral fees and disclosure before accepting any payment.

Next step

If you are ready to refer a company, register as a partner; payment paperwork is covered by the partner agreement and terms. Read the who qualifies page first to see which US companies fit.
