Sole proprietor W-9: the simplest case
If you're a freelancer or sole prop without an LLC, your W-9 is straightforward. Here's what goes where.
The short answer
If you've never formed an LLC or corporation, you're a sole proprietor by default. Your business taxes are part of your personal taxes. Your W-9 is the simplest version of this form — your name on Line 1, your address, your SSN.
The whole thing takes about two minutes.
What's a sole proprietor?
You're a sole proprietor if all three of these are true:
- You earn money from freelance work, consulting, contracting, or self-employment.
- You haven't formed an LLC, corporation, or partnership.
- You file your business income on Schedule C as part of your personal tax return.
You're a sole proprietor whether you have a "business name" (DBA, or "doing business as") or not. Whether you have an EIN or not. Whether you call yourself a "freelancer" or a "consultant" or just "Jane Smith Photography." If you didn't legally form a separate entity, you're a sole proprietor for tax purposes.
This is the default for most freelancers when they first start. You don't have to do anything to become one — you just are one the moment you earn self-employment income.
Line by line
Line 1 — Name
Your full legal name (the one on your tax return).
Line 2 — Business name (DBA)
Your business name or DBA, if you have one. Skip if you operate under your own name.
Example: if your name is Jane Smith but you do business as "Smith Studio," put "Smith Studio" on Line 2. If you just freelance under "Jane Smith," leave Line 2 blank.
Line 3a — Federal tax classification
Check "Individual / sole proprietor."
This is the default option on the form. If you're a sole prop, this is the box you check.
Line 3b — Foreign partners checkbox
Skip. Doesn't apply to sole props.
Line 4 — Exempt payee codes
Skip. It's rare for sole proprietors to claim exempt payee codes — these are mostly for tax-exempt organizations and some specific types of corporations.
Lines 5–6 — Address
Your address. Could be your home address or a business address — whatever you want associated with this client relationship.
Line 7 — Account number
Skip unless your client gave you a vendor number to write on the form. Most clients don't ask for this.
TIN box — Taxpayer Identification Number
Your Social Security Number (SSN). Or your EIN if you have one and prefer to use it.
Most sole proprietors use their SSN. If you have an EIN (more on that below), either works.
Should I get an EIN?
An EIN (Employer Identification Number) is a federal tax ID for businesses. It's like an SSN but for a business.
Sole proprietors don't have to have one — your SSN works fine. But there are reasons to get one anyway:
- Privacy. Sharing your SSN with several clients (especially online) carries some identity-theft risk. An EIN is a separate number you can give out instead.
- Banking. Some banks ask for an EIN to open a business checking account, even for sole props.
- Hiring. If you ever hire help, you'll need an EIN to run payroll.
The IRS will issue an EIN to a sole prop on request, free, in about 15 minutes online at irs.gov. You can use either your SSN or your EIN on the W-9 — most clients don't care which.
After you send the W-9
Your client uses the W-9 to file a 1099 with the IRS in January if they paid you over the year's reporting threshold (currently $600; the threshold is set to rise to $2,000 starting in 2026 per recent IRS guidance — check the current rules at the time you file).
The 1099 reports your earnings to the IRS. You use it to file your own taxes — Schedule C for the income and your business expenses, Schedule SE for self-employment tax (which is what you pay instead of having Social Security and Medicare taken out of paychecks).
You owe taxes on all your freelance income whether or not you receive a 1099. The 1099 is just paperwork — it doesn't create the tax obligation.
Common questions
I just started freelancing. Do I need a W-9 ready?
Yes. Most clients ask for one before sending payment. Have one filled out and ready to send the moment a new client asks for it. Our free tool takes about two minutes.
Can I send the same W-9 to multiple clients?
Yes. The W-9 is about you — your name, your tax ID, your address — not about a specific job. Once you've filled one out, you can send copies to as many clients as you want.
If your address or any other info changes, send updated W-9s to your active clients so the next round of 1099s has the right details.
What if I'm a sole prop AND have a W-2 day job?
Two separate forms for two separate situations. Your day job has a W-4. Your freelance clients each get a W-9. You'll get a W-2 from the day job at year-end and 1099s from the freelance clients. All of it shows up on your one tax return.
If you have meaningful freelance income on top of a day job, your W-4 alone probably won't cover the taxes you owe on the freelance side. Worth using W-4 Easy Guide to bump up your withholding, or paying quarterly estimated taxes on the freelance income.
Do I send the W-9 to the IRS?
No. You send it to your client. The client keeps it on file and uses it to fill out a 1099 for you in January. The IRS sees the info on the 1099, not the W-9 itself.
What if I formed an LLC last year?
You're not a sole prop anymore for W-9 purposes. Use our single-member LLC guide instead — the rules are different and surprisingly tricky to get right.
How private is my W-9?
The client should keep it secure — it has your SSN on it. Don't email an unencrypted W-9 to a client unless you trust their security. Most companies have a secure portal for collecting them. If your client emails you back asking for one, ask if they have a secure way to send it (file upload, encrypted email, etc.). Sending plain-text SSNs over regular email is a real identity-theft risk.
