Introduction: Why the W-9 is Google’s Most-Asked Tax Form
Each tax season, thousands of freelancers and small businesses type “What is a W-9?” into Google.
Despite being one of the simplest IRS forms, it’s also one of the most misunderstood.
If you’re a business collecting vendor details or a contractor being asked to fill one out this guide answers the 18 most common questions people ask about Form W-9.
And if you’re tired of chasing vendors for signatures, we’ll show you how GetW9.tax automates W-9 collection with one-click requests, reminders, and tamper-evident PDF records.
1. What is IRS Form W-9?
Form W-9 (“Request for Taxpayer Identification Number and Certification”) lets businesses collect a contractor’s legal name, address, and tax ID (TIN).
You don’t send it to the IRS it stays on file so the payer can prepare a Form 1099 later.
2. Who Needs to Fill Out a W-9?
Independent contractors, freelancers, consultants, and vendors generally provide a W-9 so the payer can issue the required information return (e.g., Form 1099-NEC/MISC).
- For payments made in 2025: the reporting threshold remains $600 for the calendar year.
- For payments made in 2026 and later: the threshold increases to $2,000, with inflation indexing starting in 2027. (Forms reflecting 2026 payments are filed in early 2027.) Littler Mendelson P.C.
Banks or settlement administrators may also request a W-9 for reporting things like interest, dividends, or certain legal settlements.
Note: Third-party network reporting (Form 1099-K) is separate and currently reverts to $20,000 and 200 transactions; this does not change whether a payer may ask you for a W-9. Littler Mendelson P.C.
(This is general information, not tax advice. When in doubt, consult a CPA.)
3. When Should Businesses Request W-9s?
Collect W-9s before issuing the first payment.
Doing this up-front ensures your 1099 filings are accurate and avoids scrambling for missing tax info in January.
4. Why Is Someone Requesting a W-9 From Me?
They’re required to report payments to the IRS.
Without your W-9, they may need to withhold 24 % of your payments as backup withholding a preventable penalty.
5. W-9 vs 1099 What’s the Difference?
- W-9: Completed by the payee (gives tax information).
- 1099-NEC / 1099-MISC: Issued by the payer (reports payments to the IRS).
Think of the W-9 as the input and the 1099 as the output.
6. What Information Does a W-9 Include?
- Full name and business name
- Address
- Federal tax classification (individual, LLC, C-Corp, etc.)
- Social Security Number or EIN
- Exemption codes (if applicable)
7. How Do I Fill Out a W-9?
- Download the latest form from IRS.gov.
- Enter your name, business name, address and TIN.
- Sign and date the form.
- Send it to the business that requested it not to the IRS.
💡 Tip: With GetW9.tax, vendors can complete and e-sign the form online no printing or emailing PDFs needed.
8. Do I Need to Update It Every Year?
There’s no annual renewal rule, but you should submit a new form if your business name, address, or TIN changes.
9. What Happens If I Don’t Submit a W-9?
The payer may be forced to withhold 24 % of each payment for backup withholding, and you could face penalties for missing or false information.
10. Is It Safe to Share My W-9?
Yes, if you verify the requester. Only send W-9s to legitimate clients or financial institutions.
Avoid emailing PDFs with your SSN. Instead, use a secure platform like GetW9.tax, which creates encrypted submission links and tamper-evident records.
11. W-9 vs W-4 What’s the Difference?
| Form | Used By | Purpose |
|---|---|---|
| W-9 | Contractors / Vendors | Provide TIN to payers for 1099 reporting |
| W-4 | Employees | Tell employers how much tax to withhold |
12. W-9 vs W-8 What’s the Difference?
- W-9: For U.S. individuals and entities.
- W-8: For non-U.S. persons to certify foreign status and claim tax treaty benefits.
W-9s never expire; W-8s expire every three years.
13. How Long Should I Keep W-9s on File?
Keep them for at least three years after the last tax year a payment was made or a 1099 was issued.
14. Can I Fill Out a W-9 Online?
Yes. You can digitally fill and e-sign IRS Form W-9 using secure software.
GetW9.tax lets businesses send W-9 requests with auto reminders and USPS address validation to avoid undeliverable forms.
15. What Is Backup Withholding?
If a vendor’s TIN is missing or incorrect, the IRS requires payers to withhold 24 % of payments as a temporary tax until the correct W-9 is provided.
16. Do I Need a W-9 From Every Contractor?
Yes. Collect one for every U.S. vendor, even if you pay them only once. It keeps your records clean and your 1099 process smooth.
17. Latest W-9 Updates for 2025
The IRS still uses the October 2018 version of Form W-9, but a revision is expected in 2026 to modernize electronic signature rules and clarify TIN matching procedures.
