You hire a contractor to handle a project, pay them at year-end, and realize you have no signed W-9 on file—now you’re scrambling in December with incomplete records and unclear filing obligations. Collecting W-9 forms from contractors before December 31 is one of those non-negotiable compliance tasks that small business owners often postpone until it becomes a crisis. If you don’t have a signed Form W-9 (Request for Taxpayer Identification Number and Certification) from every contractor you paid more than $600 in a calendar year, you face friction when filing 1099-NEC forms, potential backup withholding on future payments, and compliance gaps your CPA will flag. This guide walks you through exactly how and when to collect these forms, what to do if a contractor refuses, and how to organize your contractor records so December isn’t a panic month.
Whether you’re the business owner juggling the back office yourself, or the CPA supporting one, see how the platform keeps the numbers organized — your first period is free for a limited time, no credit card required.
Does this apply to your business in Florida?
If you paid any contractor $600 or more during 2026, you are required to file a Form 1099-NEC with the IRS and provide a copy to that contractor by January 31, 2027. The Florida Department of Revenue requires the same reporting for state purposes. A signed W-9 is your legal proof that the contractor confirmed their identity and tax status before you filed the 1099-NEC—without it, you cannot complete the 1099 accurately and you risk incomplete filings.
What a W-9 form actually is and why you need it
Form W-9 is a simple one-page IRS form that a contractor (or any non-employee you pay) fills out and signs to give you their Legal Name, Taxpayer Identification Number (either a Social Security Number or an Employer Identification Number), and a certification that the information is correct. It is not a tax form you file with the government—it is a record you keep on file and reference when you prepare the contractor’s 1099-NEC at year-end.
Without a completed, signed W-9, you have no legal record of the contractor’s confirmed identity and tax status. If you prepare a 1099-NEC without that signature, the IRS and state tax agencies see an incomplete filing. If the contractor never gives you a W-9 and you cannot locate them for one, you may be required to file with the contractor’s SSN marked as unverified or not provided, which triggers backup withholding rules and creates audit exposure.
When to collect the W-9 from contractors
The best time to collect a W-9 is before the first payment. Request it as part of your onboarding process—when you agree to hire the contractor, send them the form and ask them to sign and return it before work begins. This way, you have the form on file from day one and you avoid scrambling in December.
In practice, many business owners collect it at the time of first payment or shortly after. The critical deadline for your purposes is December 31—you must have a signed W-9 on file before you file the 1099-NEC on or by January 31 of the following year. If a contractor is still working for you in November or December, make collecting their W-9 part of your standard wrap-up process before year-end.
How to request and collect W-9 forms: Step by step
Step 1: Get the form. Download the current Form W-9 directly from the IRS website. The form is free and the same one every year (it may update slightly in formatting, but the fields remain standard). Print a copy for each contractor or send them a digital PDF and ask them to fill it out electronically, sign it (digital signature or printed and scanned), and return it to you via email or in person.
Step 2: Complete the form with the contractor. The contractor must fill in their Legal Name (as it appears on their tax return or Social Security card), their Address, and their TIN. If the contractor is a sole proprietor, the TIN is their SSN. If they have an LLC or S-corp, the TIN is their EIN. The contractor must also check the box(es) that describe their tax classification (sole proprietor, LLC, S-corp, C-corp, or other entity type) and certify that the information is correct by signing and dating the form.
Step 3: Verify the information makes sense. Before you file the 1099-NEC, compare the name and TIN on the W-9 to the name and TIN you used in your invoice and payment records. If there is a mismatch, contact the contractor and clarify. For example, if the contractor’s invoice says “John Smith Painting” but the W-9 says “John Michael Smith,” confirm which name matches their actual tax return so you file the 1099-NEC correctly.
Step 4: Store the form securely. Keep the signed W-9 in your contractor file or in a dedicated folder. You do not send the W-9 to the IRS or Florida Department of Revenue—it is a record you keep for your files. Retention is typically at least three to four years, and some advisors recommend keeping it for the life of your business relationship with that contractor. If you are using a digital document system, scan and archive the signed form.
Step 5: Use it to file the 1099-NEC. When you prepare the 1099-NEC for that contractor in January 2027, the W-9 on file confirms you have their correct legal name and TIN. You can file the 1099-NEC with confidence that you have met the identification requirement. If you use a payroll or 1099 filing service, they will typically request a copy of the W-9 or ask you to confirm the contractor’s TIN so they can match it to the 1099 data.
What to do if a contractor won’t give you a W-9
It is rare, but occasionally a contractor refuses to sign a W-9 or becomes unreachable. If a contractor declines, explain that a signed W-9 is required by the IRS before you can make any payment over $600—it is not optional. If they still refuse, you have limited options. You may file the 1099-NEC without a W-9 on file, but you must report the contractor’s TIN as “not obtained” or similar, and backup withholding rules may apply to future payments.
In practice, a refusal usually means one of two things: the contractor is not legally authorized to work in the U.S. and is avoiding tax documentation, or they are disorganized and haven’t provided it yet. If the latter, a friendly reminder often works. If the former, you may need to stop making payments and consult a CPA or employment attorney, because hiring someone without a W-9 or valid work authorization can expose you to compliance and liability issues.
Common mistakes when collecting W-9 forms
One frequent mistake is collecting a W-9 but not verifying the name and TIN before filing the 1099-NEC. If the contractor provides a nickname on the W-9 (e.g., “Bobby” instead of “Robert”) or if the TIN is wrong by one digit, the 1099-NEC you file will not match the contractor’s tax return and they will have trouble reconciling their income. The fix: compare the W-9 name and TIN to the contractor’s invoices and your payment records, and ask the contractor to clarify any discrepancies before year-end.
A second mistake is not collecting a W-9 at all if a contractor is paid less than $600 in a single year—then assuming you don’t need one in future years. While it is true that you do not have to file a 1099-NEC for payments under $600, having a W-9 on file is still smart practice. If that contractor works for you again in the next year and you pay them $600 or more, you already have their information and you avoid the December scramble. The fix: collect a W-9 for every contractor relationship, regardless of the amount paid in the first year.
A third mistake is failing to update a W-9 if a contractor’s name, address, or tax status changes. If a contractor changes from a sole proprietor to an LLC and gets a new EIN, they should provide an updated W-9. If you file a 1099-NEC using an old EIN or outdated name, the IRS and contractor may not reconcile the filing correctly. The fix: ask contractors to notify you if their tax status or name changes, and request an updated W-9 at the start of each year or before the next payment.
A fourth mistake is collecting a signed W-9 but then losing it or storing it so poorly that you can’t find it when you need it. If you cannot locate the W-9 at filing time, you may file the 1099-NEC anyway, but with less confidence in its accuracy, and you lose the legal protection of having a documented, signed verification from the contractor. The fix: establish a simple filing system—whether digital or paper—where each contractor has a folder, and place the signed W-9 in that folder immediately after you receive it.
Organizing contractor records for 1099 filing
The easiest way to stay on top of W-9 collection is to build it into your contractor onboarding process. When you first hire a contractor, send them a welcome email that includes the W-9 form and a simple instruction sheet: “Please fill out this form, sign it, and return it to us before we issue your first payment.” Many contractors will complete it right away because it is straightforward.
If you work with the same contractors year over year, maintain a master list of contractors with their names, TINs, payment amounts, and a note of whether you have a current W-9 on file. A simple spreadsheet works fine: columns for contractor name, business type (sole prop, LLC, S-corp, etc.), TIN, total paid in the year, W-9 on file (yes/no), and date received. By October or November each year, review the list and follow up with any contractor for whom you do not have a signed W-9.
If you are using an outsourcing platform to organize and categorize your transaction data, you can store W-9 copies in that system or link to them in your file so your CPA can reference them during 1099 preparation. This reduces the friction between you and your CPA and ensures that the 1099-NEC data matches your signed documentation.

Frequently Asked Questions
Can I use an electronic signature or copy of a W-9?
Yes. The IRS accepts electronically signed W-9 forms and scanned copies. The contractor can fill out a digital PDF, sign it electronically, and email it to you, or they can print, sign, scan, and return it. What matters is that the form is complete, signed by the contractor, and legible.
What if a contractor doesn’t have an SSN or EIN?
If a contractor is a non-resident alien without a U.S. tax identification number, they may apply for an Individual Taxpayer Identification Number (ITIN) from the IRS. If they do not have an SSN, EIN, or ITIN, you may still pay them, but you cannot file a 1099-NEC and backup withholding rules apply. This situation is complex and best discussed with a CPA or tax attorney to confirm your obligations.
Do I need a new W-9 every year?
No. A signed W-9 remains valid indefinitely unless the contractor’s name, address, or tax status changes. However, best practice is to ask contractors to confirm their information at the start of each year and provide an updated W-9 if anything has changed. Some businesses send a simple confirmation email instead of a full form if nothing has changed.
What if I already paid a contractor and realized I don’t have a W-9?
Contact the contractor immediately and request a signed W-9. Explain that you need it to prepare their 1099-NEC at year-end and to stay compliant. Even if payment has already been made, a retroactive W-9 is valid and acceptable. If the contractor is unreachable, you may file the 1099-NEC without the W-9 on file, but with backup withholding considerations—consult your CPA.
Does a W-9 mean the contractor is an independent contractor and not an employee?
No. A W-9 is a tax identification form—it confirms the contractor’s TIN and does not determine employment status. Employment classification (employee vs. contractor) is based on facts and circumstances (how much control you exercise, benefits provided, permanence of the relationship, etc.). Signing a W-9 does not protect you if the IRS or Department of Labor later reclassifies the contractor as an employee. If you are unsure about the classification, consult a CPA or employment attorney.
