The tax form that connects contractors to 1099s.
Form W-9 establishes tax identity for every contractor relationship. You collect one from contractors you pay. You provide one to clients who engage you. It's the anchor for 1099 filing and IRS matching.
You collect a W-9 from every independent contractor, freelancer, or self-employed vendor before payments reach $2,000 in a calendar year. The $2,000 threshold is new for 2026. It replaces the previous $600 threshold and will index for inflation starting in 2027.
It establishes tax identity: legal name, business structure, and taxpayer identification number (TIN). That information drives the 1099-NEC your client files at year-end, and the ones you file for contractors you pay.
Miss a W-9 and you're managing backup withholding or facing IRS notices at tax time. Here's when to collect them, what happens when a contractor won't provide one, and how to complete one when a client asks.
SurePayroll By Paychex tracks contractor payments as you make them and generates 1099s from W-9 information already on file. See how it works.
What is Form W-9?
The W-9, or Request for Taxpayer Identification Number and Certification, is divided into two parts.
Part I collects identifying information: legal name as it appears on the contractor's federal tax return, business name or DBA if different, entity type (sole proprietor, sole proprietorship, single-member LLC, limited liability company, S corporation, C corporation, partnership, or trust), taxpayer identification number (either a Social Security Number (SSN) or Employer Identification Number (EIN)), and mailing address.
Part II is the certification: The contractor signs to confirm their TIN is correct, that they're not subject to backup withholding, and that they are earning in the U.S. (a U.S. citizen, resident alien, or domestic business entity).
That TIN is the anchor for your 1099 filing and the IRS matching process that follows. You use it to prepare Form 1099-NEC at year-end. The IRS uses it to match the nonemployee compensation you reported against the income the contractor declared on their income tax return.
An incorrect TIN creates a matching failure and will require you to start backup withholding on future payments. The IRS also offers a TIN matching program so you can verify a contractor's name and TIN against IRS records before you file.
Form W-9 is different from Form W-4, the withholding form your employees complete when hired. If you manage both employees and contractors, you use both forms, one for each worker relationship.

When you need to collect a W-9
Request a W-9 from a new contractor before you issue the first payment to keep your records current for tax season.
File a Form 1099-NEC with the IRS by January 31 for every contractor you pay $2,000 or more in a calendar year. The W-9 is your source document for that filing.
Who needs to provide a W-9
Keep a complete form W-9 on file for any contractors you pay $2,000 or more in a calendar year. You'll also keep one on file for anyone you pay rent to.
Who doesn't need to provide a W-9
Employees complete Form W-4, not a W-9. Payments to independent contractors under the $2,000 annual threshold don't require a W-9 for 1099 purposes, though collecting one upfront protects you if the engagement grows. Most payments to C corporations are exempt. Attorney fees are the exception.
LLCs and S Corps
If you pay an LLC, whether you need a W-9 depends on how that LLC files for federal tax purposes. You are required to collect a W-9 from most single-member LLCs and S corporations.
Independent contractor vs. employee classification
Before you request a W-9, make sure you've classified the worker correctly. If they should be classified as an employee, you need a W-4, not a W-9.
Misclassification creates tax and legal problems you don't want to inherit. Get the independent contractor vs. employee decision right first.
What happens if a contractor won't provide a W-9
You have three options when a contractor won't provide a W-9. All three are grounded in IRS rules around missing taxpayer information. Every situation is different, and a tax advisor or attorney can help you weigh yours.
Option 1: Hold payment until you receive a completed W-9
You're collecting what you need to pay correctly and report the payment consistently. Most contractors who push back comply once they understand the alternative.
Option 2: Pay, and apply backup withholding
If you pay a contractor without a valid W-9 on file, or if the IRS notifies you that the TIN on file is incorrect, you need to withhold 24 percent of each payment and send it to the IRS. Backup withholding is how the IRS collects on income it can't verify through a matching TIN. A W-9 with a valid TIN is your verification of record.
You're required to use Form 945 to report backup withholding taxes annually and deposit withheld amounts on your standard federal tax deposit schedule. Your 1099 filing obligations remain in place. Backup withholding does not replace your 1099 obligation. You file both.
The contractor recovers the withheld amount when they file their income tax return. It applies as a credit against their federal income tax liability.
Option 3: End the contractor relationship
If a contractor refuses to provide a W-9 and you're not prepared to manage backup withholding, you can end the engagement.
A W-9 is standard procedure for any paid contractor relationship. A refusal to provide one signals an issue on the contractor's side that you assume responsibility for.
What to do with W-9s after you collect them
Once you've collected the W-9, store it, track payments, and file at year-end.
Store W-9s securely for at least four years from the date you file the related 1099-NEC. Keep physical copies in a locked file or store them as encrypted digital tax documents.
The IRS can request them as part of a review of your information returns. A W-9 with a correct taxpayer identification number, that you've collected in good faith, is your documentation if the IRS audits your 1099 filings.
Track every contractor payment throughout the year. With the W-9 on file and payment records tracked through the year, you have everything you need to prepare Form 1099-NEC. Contractors who hit the annual threshold receive a 1099-NEC. Keep payment records current through the year.
Use the W-9 information (legal name, TIN, and mailing address) to prepare Form 1099-NEC at year-end for each qualifying contractor. File with the IRS and deliver a copy to the contractor by January 31. The IRS matches the TIN and nonemployee compensation you reported against what the contractor declared on their income tax return. When you match your records, the filing clears. Mismatched records (wrong TIN, transposed name) trigger notices to both parties.
Note that Form 1099-MISC still applies to certain payment types like rent, prizes, and legal settlements, but nonemployee compensation moved to Form 1099-NEC in 2020. For the contractors you pay for services, 1099-NEC is the correct form.
If you manage both W-2 employees and 1099 contractors in the same business, keep those records separate and reconcile both before you generate year-end forms.
Tracking contractor payments and monitoring the $2,000 threshold works fine for one or two contractors. Add more and manual tracking becomes a liability.
SurePayroll tracks contractor payments as you make them. When someone hits $2,000, you'll know. At year-end, 1099s generate from the W-9 information already on file. If you're running payroll for employees too, both W-2s and 1099s come from the same system.
How to fill out Form W-9
When a client engages you for contract work, they'll ask you for a W-9. To complete your W-9 correctly, download the latest version from the IRS website. Form W-9 instructions update when tax law changes, and an outdated form can create issues with your client's records.
Line 1: Legal name
Enter your legal name exactly as it appears on your federal tax return. For a sole proprietor or individual, that's your full personal name. For a business entity, it's the registered entity name.
Line 2: Business name or DBA
Enter your business name or trade name here if it differs from your legal name. If you operate as a sole proprietorship under your own name with no separate DBA, leave this blank.
Line 3: Federal tax classification
Check the box that matches how your business entity files for federal tax purposes. If you're an LLC, enter the letter indicating how it's taxed: C, S, or P. If your LLC elected S corporation status, check 'Limited liability company' and enter 'S', not the S corporation box. A mismatch here creates a discrepancy the IRS will flag. If you're uncertain, your CPA can confirm your classification quickly.
Line 4: Exemptions
Leave blank unless you have a specific exempt payee code or FATCA exemption that applies. As an independent contractor or self-employed individual, leave this line empty. The Form W-9 instructions on the IRS website list the applicable codes for tax-exempt organizations, financial institutions, and entities with FATCA reporting exemptions.
Lines 5-6: Address
Enter your current mailing address. The requester uses this to send your copy of Form 1099-NEC at the end of the year.
Part I: Taxpayer Identification Number
Enter your SSN or EIN, your tax ID number for federal income tax purposes.
If you're a sole proprietor, your SSN works legally. If you have an EIN, use it — it keeps your SSN off documents that move through client systems. Don't have an EIN? You can apply through the IRS website at no cost.
If you are a U.S. resident but do not have a Social Security Number, you can use your individual taxpayer identification number (ITIN) here instead.
Part II: Certification and signature
Sign and date the form to certify that your correct taxpayer identification number is correct, that you're not subject to backup withholding (unless notified by the IRS otherwise), and that you're a U.S. citizen or based in the U.S. for federal tax purposes. An unsigned W-9 is incomplete and will be returned by the requester for a signature.
Automate W-9 and 1099 filing or own it manually
You've collected W-9s, tracked payments, and know what's due at year-end. That foundation works. It won't scale.
Add contractors and you multiply the work: another W-9 to secure and store, another payment threshold to monitor, another 1099 to file by January 31. Run employee payroll and you're reconciling two separate year-end processes when deadlines tighten.
SurePayroll By Paychex runs both from one account. Contractor payments track as you make them. Employee payroll runs on schedule. Year-end forms generate for everyone — W-2s and 1099s from the same system.
You can track this manually. You decide whether that's where your time goes when January comes.
