Form W-9 filler

Fill IRS Form W-9. Get the LLC tax box right - then send it to your client.

Enter your details on the left; the W-9 fills in real time on the right. We pre-select the LLC tax classification the way most contractors should fill it: that's the #1 thing people get wrong. Pick a tier inside the form below.

1. Federal tax classification

The #1 thing people get wrong on the W-9. We pre-select the most common contractor profile - change it only if your situation is different.

2. Your name & business

Line 1 is your LEGAL name (as it appears on your tax return). Line 2 is your trade name or DBA only if different.

For single-member LLCs: the owner's name, NOT the LLC name
3. Address

Where the requester should mail your 1099 at year-end.

4. Taxpayer Identification Number (TIN)

Either your SSN (sole proprietors usually) or your EIN (LLCs, corporations, partnerships). Pick one.

Encrypted. Never stored in our system unless you choose the $79 vault tier.
5. Requester & certification

The company asking for your W-9. In the $79 Secure Delivery tier we email the signed W-9 directly to their inbox.

Required for the $79 Secure Delivery tier

Form W-9 is not filed with the IRS - it is a certification you give to the business that requested it (your client, broker, or payer). They use it to issue 1099s to you later. Our $79 Secure Delivery tier emails the signed W-9 directly to your requester and stores a permanent copy in your File.Business vault, so the next time a client asks for one you reply in one click.

FAQ

About the Form W-9 filler.

What does the $9 Blank tier include?
Yes. The blank Form W-9 PDF is the official IRS form; you can download it for $9 (official IRS form, file yourself). The paid tiers add convenience: we fill it correctly (especially the LLC tax box), print and mail it for you, or securely email it to your client and keep a permanent copy in your vault.
What box do I check if I have an LLC?
Single-member LLCs disregarded for federal tax check "Individual / sole proprietor / single-member LLC" - NOT the LLC line. Multi-member LLCs taxed as partnerships check "Partnership." LLCs with an S-Corp election (Form 2553) check "S Corporation." Only check "LLC - Other" if a CPA specifically told you to. Our filler pre-selects the most common single-member LLC answer.
Whose name goes on Line 1?
Your LEGAL name as it appears on your federal tax return. For sole proprietors and single-member LLCs that's the OWNER's name, not the business name. The business name goes on Line 2 (if different).
Should I use my SSN or EIN?
Sole proprietors and single-member LLCs disregarded for federal tax usually use SSN. Multi-member LLCs, partnerships, corporations, and SMLLCs that have their own EIN use the EIN. The IRS will accept either as long as Line 1 matches what's registered with the IRS for that TIN.
Is the W-9 filed with the IRS?
No. The W-9 is given to the COMPANY that requested it - usually a client you contract with, a brokerage, or a bank. They keep it on file and use it to issue you a 1099 at year-end if you crossed $600 in payments.
Is it safe to type my SSN into a web form?
In our filler your TIN is encrypted in your browser only and never transmitted to our servers unless you choose the $79 Vault tier. In the $79 tier it's stored in your SOC 2 Type II encrypted vault so future W-9 requests are one-click. Always verify HTTPS and a recognizable domain (file.business) before entering a TIN online.
Is my data saved?
Your inputs autosave to your browser (localStorage) so you can come back later. No data goes to our servers unless you choose a paid tier. TINs are never transmitted in the free tier.
