What is W-9?

Need to get a W-9 form filled fast? Form W-9 is the IRS document a requester uses to collect a US person's taxpayer identification number (TIN) and certifications when an information return or backup-withholding rule may apply. Contractors often receive one when they start with a client, but banks, brokers, real-estate businesses, debt cancellers, and other requesters use it too. JustFill loads the current official blank and lets you complete it without printing or installing software; the first clean completed download is included.

Who fills out W-9?

  • Independent contractors and freelancers whose US client requests taxpayer information — reporting thresholds depend on the payment and return involved
  • Sole proprietors invoicing US clients that need a certified name and TIN
  • US-owned LLCs and US corporations providing services to businesses
  • Vendors registering with a new customer who reports payments to the IRS
  • Anyone opening certain bank or brokerage accounts that require backup withholding info

Field-by-field breakdown

What each section of W-9 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Line 1 — Name

Your legal name as shown on your tax return.

Line 2 — Business name

Disregarded entity name or DBA, if different from Line 1.

Lines 3a–3b — Federal tax classification

On line 3a, select the classification that applies to the name on line 1. Partnerships, trusts, and estates with foreign partners, owners, or beneficiaries also review the line 3b checkbox and its instructions.

Line 4 — Exemptions

Most filers leave blank. Used by certain corporations and tax-exempt organizations.

Lines 5–6 — Address

Where the payer should mail your 1099 at year end.

Part I — TIN

Your Social Security Number (SSN) for individuals, or your Employer Identification Number (EIN) for businesses.

Part II — Certification

When certification is required, sign and date under penalties of perjury. The certification covers the TIN, backup withholding, US-person status, and any FATCA exemption code entered.

Common mistakes to avoid

  • 1Putting your business name on Line 1 when you are a sole proprietor — Line 1 should be your individual name.
  • 2Assuming every requester can accept a typed or drawn signature. Electronic W-9 collection systems must meet IRS requirements, and the requester decides which signing method it accepts.
  • 3Sending the completed W-9 to the IRS or an unintended recipient. It contains a sensitive TIN and normally goes only to the requester who asked for it.
  • 4Using an old version of the form. The IRS occasionally updates the W-9; always start from the current PDF at irs.gov.

W-9 example — what a filled-out form looks like

A fictional sole proprietor is giving a new US client the name and taxpayer information the client requested. The example is intentionally masked and does not provide a usable TIN.

Line 1 — Name

ALEX EXAMPLE

A sole proprietor uses the individual name shown on the tax return.

Line 2 — Business name

EXAMPLE DESIGN STUDIO

The trade name goes here because it differs from line 1.

Line 3a — Classification

Individual / sole proprietor

This describes the fictional filer; do not copy it if your tax classification differs.

Lines 5–6 — Address

100 SAMPLE STREET — AUSTIN, TX 78701

Part I — TIN

XXX-XX-6789

Masked on purpose. Enter only your own SSN or EIN in the real form.

Part II — Certification

ALEX EXAMPLE — date signed

Use the signing method accepted by the requester.

These values are made up. They are here to show what belongs on each line, not to be copied — every name, number, and address on your own W-9 has to be your own. LLCs, corporations, partnerships, trusts, estates, exempt payees, and filers with foreign owners can complete the name, classification, and TIN lines differently. Check the current IRS instructions for your circumstances.

Frequently asked questions

The IRS form itself is free. JustFill is free to start and includes your first clean, watermark-free completed PDF download; additional clean exports use a one-time pack or a monthly plan.
No. You send the completed W-9 to the payer (client, vendor, or institution) who requested it. They keep it on file and use it to issue a 1099 at year end.
A requester may collect W-9s electronically through a system that meets IRS requirements for identity, integrity, records, and an electronic signature under penalties of perjury. A typed name or drawn mark is not universally sufficient by itself, so confirm the accepted method with the requester.
After applying, enter "Applied For" in the TIN space, sign and date the form, and give it to the requester. The 60-day relief from backup withholding applies only to interest, dividends, and certain readily tradable instruments; other payments can be subject to backup withholding until you provide the TIN.
