What is a W-9 form and when do you need one?

Learn what IRS Form W-9 collects, who completes it, how a payer uses it, and the 2026 information-reporting threshold changes.

Last updated: October 9, 2026

Direct answer

A W-9 gives a requester your legal name, tax classification, address, and taxpayer identification number so they can prepare applicable information returns and meet withholding rules. You give the completed form to the requester, not the IRS. A requester may ask for a W-9 even when a payment is below a reporting threshold.

Simple explanation

A W-9 is a tax-information form, not a bill or an income tax return. The dollar threshold for some information returns changed for payments made in 2026, but that does not make payments below the threshold tax-free or stop a payer from requesting a W-9.

How Form W-9 is used

  1. 1

    A payer requests your current tax information

    A client or business may ask for a W-9 before paying you so it can document the payee’s name, tax classification, address, and TIN.

  2. 2

    Complete the form using your federal tax classification

    Use the name and TIN that match the tax classification. A disregarded single-member LLC generally uses the owner’s name and SSN or EIN for federal income-tax reporting; check the current W-9 instructions.

  3. 3

    Return it securely to the requester

    Do not send Form W-9 to the IRS. It contains sensitive information, so use the requester’s secure delivery method.

  4. 4

    Do not confuse a reporting threshold with taxable income

    For many business payments reported on Form 1099-NEC, the federal threshold is $2,000 for payments made in calendar year 2026 (up from $600 for payments made before 2026). Other forms and payment types have distinct rules; a payer may request a W-9 below a threshold.

  5. 5

    Keep the income records either way

    Whether or not a 1099 is issued, report taxable income according to the tax rules that apply to you. A form is information reporting, not the complete tax analysis.

Key takeaways

  • A W-9 gives a requester your tax name, classification, address, and TIN.
  • You return it to the requester securely; you do not file it with the IRS.
  • The general 1099-NEC threshold is $2,000 for payments made in 2026; other forms have separate rules.
  • A reporting threshold does not make income below it tax-free and does not prevent a requester from asking for a W-9.

Frequently asked questions

Do I send Form W-9 to the IRS?

No. You give the completed W-9 to the business or payer requesting it. The requester uses it for information reporting and withholding compliance.

Is the 2026 1099-NEC threshold still $600?

No. For payments made in calendar year 2026, the IRS says the threshold for many Form 1099-NEC service payments is $2,000. The threshold was $600 for payments made before 2026. Exceptions and other information-return types have separate rules.

If I am paid less than the 1099 threshold, is the income tax-free?

No. Information-return thresholds determine when certain forms must be filed; they do not decide whether income is taxable. Keep accurate records and report income as required.

Can a client still ask for a W-9 below $2,000?

Yes. A payer may request tax information before paying a contractor, regardless of whether it expects the payment to reach a filing threshold.

Which TIN should a single-member LLC use?

For federal income-tax reporting, a disregarded single-member LLC generally provides the owner’s name and SSN or EIN, not the LLC’s EIN. The LLC uses its EIN for certain employment or excise-tax reporting. Follow the current Form W-9 instructions.
