What W-9 Form Filler does, with a checked example
A W-9 is the form a US person gives to someone paying them, so the payer can report the income to the IRS on a Form 1099. This tool recreates the official form as an interactive page: you enter your name, business name, address, tax classification, and TIN, tick the certification boxes, and it assembles a completed PDF you can email or print. It runs entirely in your browser, so the form - including your Social Security number - never leaves your machine. The surprise most people hit: you do not file a W-9 with the IRS. It goes to the requester, and it is not complete until Part II is signed and dated.
Worked example
A concrete input and expected output from the current implementation.
Input
Name: Jane Doe / Business name: Doe Design Studio / Address: 210 Main St, Portland, OR 97204 / Classification: Individual/sole proprietor / TIN: 123-45-6789 (SSN) / Signature and date: Jane Doe, 2026-08-16
->
Expected output
A completed W-9 PDF with line 1 'Jane Doe', line 2 'Doe Design Studio', the Portland address, the 'Individual/sole proprietor' classification box checked, SSN 123-45-6789 in Part I, and the certification in Part II signed and dated, ready to email to the client that requested it.
Each entered value maps to the line the official form assigns to it, and the signature and date in Part II are what make the form complete for the requester. The tool maps and renders; it does not compute anything from the entries.
