Why Does a Sweepstakes Sponsor Ask for a W-9?

A sweepstakes sponsor asks for Form W‑9 to collect a U.S. winner's name and taxpayer identification number for tax reporting. The request alone does not mean anything is wrong with the prize.

Form W‑9 certifies that the taxpayer identification number is correct and that the signer is a U.S. person. According to the IRS Form W‑9 instructions, a requester uses that information to prepare an IRS information return.

What does the sponsor do with the W‑9?

A business sponsor generally reports qualifying prizes on Form 1099‑MISC. The sponsor needs the winner's taxpayer identification number—usually a Social Security number or employer identification number—to complete that form. For 2026, the reporting threshold is generally $2,000 in prizes and awards paid to one recipient, according to the IRS reporting FAQ.

IRS instructions classify non-wager sweepstakes prizes as "other income" on Form 1099‑MISC, while wager-based winnings use Form W‑2G.

Is the reporting threshold still $600?

Not for qualifying prize payments made after December 31, 2025. The frequently repeated $600 figure is outdated for these payments; the 2026 threshold is $2,000 and is scheduled for inflation adjustment after 2026. A reporting threshold determines when the sponsor generally must issue an information return.

It does not determine whether the prize is taxable, and it does not prevent a sponsor from requesting tax information while verifying a winner or preparing its records.

Do you owe tax without a 1099?

A prize generally counts as income even when the sponsor does not send a tax form. The IRS explains in Publication 525 that winners include cash prizes in income and report noncash prizes at fair market value. For example, winning an item worth $900 may create $900 of taxable income even though it falls below the 2026 reporting threshold.

Keep the prize notice, rules, valuation information, and any Form 1099‑MISC you receive.

When should a W‑9 request raise concern?

A W‑9 contains sensitive identifying information, so confirm who is requesting it before submitting the form. Compare the message with the sweepstakes rules and contact the sponsor through independently located contact information if anything seems inconsistent. A W‑9 does not make an upfront charge legitimate.

The Federal Trade Commission says real sweepstakes prizes are free, so do not pay a supposed tax, shipping charge, processing fee, or release fee to receive one. Useful checks include:

• Confirm that you entered the named sweepstakes.
• Match the sender and prize with the published rules.
• Ask why the form is required and how it should be returned.
• Avoid sending tax information through an unexpected link or unsecured reply.
• Independently contact the sponsor if the request includes payment instructions.

What if you are not a U.S. person?

Form W‑9 is for U.S. persons, including resident aliens. A nonresident alien generally provides Form W‑8BEN or Form 8233 instead, and prize payments to foreign persons generally face 30% withholding.

Do not sign a W‑9 merely because a prize notice includes one. Tell the sponsor that you are not a U.S. person and ask which applicable tax form and submission method it requires.

A missing or incorrect taxpayer identification number can trigger backup withholding, generally at 24% for applicable reportable payments. Check your legal name and identification number carefully before signing.
