It's mid-November, and you've just pulled your vendor payment report. You need to file 1099-NECs by January 31st for anyone you paid $600 or more, but half your contractor files are missing W-9s. Some forms have illegible TINs, others show a business name that doesn't match your payment records, and a dozen contractors haven't responded to your emails at all.
To collect W-9s from contractors efficiently, send a clear written request with a firm deadline, provide the blank IRS Form W-9, explain why you need it, and follow up systematically with non-responders. The IRS requires you to request W-9 information before filing 1099s, and if you don't have a valid TIN on file, you may face backup withholding obligations and penalties up to $290 per unfiled or incorrectundefinedform in 2024.
This guide walks you through the complete process AP teams use to collect W-9s before year-end, from identifying who needs to submit forms to handling the contractors who ghost your requests.
Why You Must Collect W-9s Before Filing 1099s
The W-9 form serves one critical purpose: it gives you the contractor's legal name, business structure, and Taxpayer Identification Number (TIN) so you can file accurate 1099-NEC forms with the IRS. Without this information, you cannot complete Boxundefined(taxpayer name) or Boxundefined(TIN) on the 1099-NEC.
The IRS doesn't accept "I tried to get it" as an excuse. If you fail to file correct 1099s by the deadline, you face:
- $50 to $290 per form depending on how late you file
- Backup withholding requirements of 24% on future payments if you lack a valid TIN
- Potential IRS penalties for willful disregard starting at $580 per form
More practically, incomplete W-9s create chaos during the busiest weeks of Q1. Scrambling to track down a contractor's EIN on January 28th when they're traveling overseas is not a position you want to be in.
Identify Which Contractors Need to Submit a W-9
Before you send a single email, pull your accounts payable report and identify everyone who requires a 1099-NEC. You need to collect W-9s from:
- Unincorporated contractors: sole proprietors, single-member LLCs, and partnerships who provided services (not goods)
- Any vendor or contractor paid $600 or more during the tax year for services
- LLCs taxed as partnerships or disregarded entities even if they sound like corporations
You do not need W-9s from:
- C-corporations and S-corporations (with limited exceptions)
- Contractors you paid through credit card or PayPal, since payment processors issue 1099-Ks
- Anyone you paid less than $600 total for the year
- Employees who receive W-2s
Check Boxundefinedon any existing W-9s you have on file. If a contractor marked "C-Corp" or "S-Corp," you typically don't need to issue them a 1099. If that box is blank or shows "Individual/sole proprietor" or "LLC," you need a 1099.
The Step-by-Step Process to Collect W-9 Forms
Step 1: Send Your Initial Request Early
Start collecting W-9s in October or early November, not December. Contractors get buried in year-end client work, and your request will sit unread if you wait until the holidays.
Your initial email should include:
- A clear subject line: "Action Required: W-9 Form Needed forundefinedTax Filing"
- Why you're asking: "We're required to collect W-9 forms from all contractors paid $600+ this year to file accurateundefinedforms with the IRS."
- The deadline: Give them 10-14 days, with a specific date
- The form itself: Attach a blank W-9 PDF or provide a link
- Submission instructions: Tell them exactly where to send it (email, portal, etc.)
Step 2: Use a W-9 Email Template That Gets Responses
Here's a template that balances professionalism with urgency:
Subject: W-9 Form Required for [Company Name] Tax Filing – Due [Date]
Hi [Contractor Name],
We're preparing our annualundefinedfilings and need a completed W-9 form from you by [specific date].
We paid you $[amount] in 2024, which means we're required by the IRS to issue you a 1099-NEC and report your taxpayer information.
Please complete the attached W-9 form and return it to [email/portal link] by [deadline]. This should only take 2-3 minutes.
What we need:
- Your legal name (or business name)
- Social Security Number or EIN
- Current mailing address
- Signature and date
If you have questions about how to complete the form, the IRS instructions are on pageundefinedof the PDF.
Thanks, [Your Name]
Step 3: Track Responses and Follow Up Systematically
Create a simple spreadsheet to track W-9 collection status:
- Contractor name
- Amount paid in 2024
- W-9 on file? (Yes/No/Incomplete)
- Initial request sent (date)
- Follow-up #1 sent (date)
- Follow-up #2 sent (date)
- Form received (date)
Send your first follow-up 5-7 days after the initial request. Keep it brief: "Following up on my email below – we still need your W-9 by [date] to avoid penalties. Please reply if you have any questions."
Send a second follow-up 2-3 days before your deadline with more urgency: "Final reminder: we need your completed W-9 by end of day [date]. Without this, we may be required to withhold 24% of future payments under IRS backup withholding rules."
Step 4: Handle Non-Responsive Contractors
If a contractor still hasn't responded after two follow-ups, you have limited options:
Use existing information carefully: If you have a signed contract with their SSN or EIN, you may be able to use that, but only if you're certain it's current and accurate.
Search IRS TIN Matching: The IRS offers a TIN Matching program that lets you verify name/TIN combinations before filing, but you need to enroll in advance.
Withhold on future payments: If a contractor refuses to provide a W-9 after repeated requests, you're required to begin backup withholding at 24% on all future payments.
File anyway with the information you have: If you have a TIN from a previous year's W-9 and the contractor is simply non-responsive (not refusing), you can file theundefinedusing that information. Document your multiple attempts to request an updated form.
The IRS cares that you made a reasonable effort to solicit the information. Save all your request emails and follow-ups as documentation.
Common W-9 Mistakes That Delay Collection
Even when contractors respond, the forms often come back with errors that force another round of back-and-forth:
Missing signature: The W-9 isn't valid without a signature under penalty of perjury. No exceptions.
Illegible TIN: When contractors handwrite their SSN or EIN, numbers often blur or get misread. Ask them to type it clearly or provide it separately in the email body.
Name mismatches: The name in Boxundefinedmust match IRS records exactly. "Mike's Consulting" won't match if the IRS has "Michael Rodriguez" on file. When in doubt, ask contractors to use their legal name or registered business name.
Blank business entity box: Boxundefinedmust show the tax classification. If it's blank, you don't know whether to issue aundefinedat all.
Old addresses: Contractors move. If their W-9 shows an address from three jobs ago, they won't receive theirundefinedcopy, and it may get returned to you.
Build these checks into your review process before you mark a W-9 as "complete" in your tracking spreadsheet.
Automate W-9 Collection With the Right Tools
If you're managing W-9 collection through email attachments and spreadsheets, you're spending 5-10 hours per year on administrative work that software handles automatically.
Collect1099 lets you send W-9 requests in bulk, automatically reminds contractors who haven't submitted, validates TINs in real-time, and stores everything securely in one place. When January arrives, you can generate and e-file all your 1099-NECs directly through the same platform. For AP teams managing 20+ contractors, the time savings typically pay for the software in the first year.
Set Up a W-9 Collection Process for Next Year
Once you survive this year's scramble, put a repeatable process in place:
Collect W-9s before the first payment: Make W-9 submission a required step in your contractor onboarding. Don't issue payment until the form is on file. This eliminates 90% of year-end panic.
Review W-9s quarterly: Every quarter, pull a report of new contractors and verify you have W-9s on file. Catching a missing form in March is easier than December.
Send annual confirmations: Each October, send a bulk email asking all contractors to confirm their W-9 information is still current. Those who have moved or changed business structures can update their forms during a slow period.
Use a centralized system: Whether that's a shared drive, a vendor management portal, or dedicatedundefinedsoftware, store all W-9s in one searchable location with restricted access. Digging through email attachments across multiple team members' inboxes is a waste of time.
What to Do If You Miss the Deadline
Sometimes despite your best efforts, a contractor simply won't respond, and you reach January without a valid W-9. Here's your fallback plan:
File theundefinedusing the best information you have (name, address, and TIN from past records or contracts), then immediately send the contractor a B Notice after you receive IRS notification of a mismatch. Document every attempt you made to collect the W-9.
The penalty for filing an incorrectundefineddrops significantly if you can prove you made reasonable efforts to obtain correct information and file a correction withinundefineddays of discovering the error.
For completely unresponsive contractors with no TIN on record, consult your tax advisor. You may need to file theundefinedwith the TIN field blank and check the "second TIN solicitation" box, but this should be a last resort.
Frequently Asked Questions
Can I require contractors to submit a W-9 before I pay them?
Yes, and you should. There's no law preventing you from making W-9 submission a condition of payment or onboarding. Most businesses include W-9 collection as part of their vendor setup process. If a contractor refuses to provide a W-9, you're required to withhold 24% backup withholding on their payments, and you can choose not to work with them at all.
How long is a W-9 form valid?
A W-9 remains valid until the contractor's information changes. The IRS doesn't require annual W-9 updates, but it's best practice to request confirmation every 1-2 years to catch address changes, business structure changes, or EIN updates. If a contractor tells you their business information has changed, request a new W-9 immediately.
What if a contractor refuses to provide their SSN on a W-9?
A contractor cannot refuse to provide their taxpayer identification number if they want to avoid backup withholding. Explain that the W-9 is an IRS requirement, not your company policy. If they're concerned about security, offer to accept the form through a secure portal rather than email, or allow them to provide the last four digits in initial communication and the full number through a phone call you document.
Do I need W-9s from contractors I paid through PayPal or Venmo?
Generally no, if you paid through a payment processor or credit card. Third-party payment networks issue 1099-K forms for contractors who receive over $600 in payments (as of 2024), so you don't issue a 1099-NEC. However, if you paid the same contractor sometimes through PayPal and sometimes through direct bank transfer or check, you need to track the total and potentially issue a 1099-NEC for the non-payment-processor amounts.
Can I collect W-9 information without using the official IRS form?
Yes, you can collect the same information through an online form, vendor portal, or other system as long as you gather all required W-9 fields: name, business name (if different), tax classification, address, TIN, and signature under penalty of perjury. Manyundefinedsoftware platforms offer custom W-9 collection forms that feed directly into your filing system. The information just needs to be complete and certified by the contractor.
Get Ahead of Next Year'sundefinedSeason
The difference between a smoothundefinedseason and a chaotic one comes down to collecting W-9s before you need them. Build W-9 collection into your contractor onboarding process, maintain a clean filing system, and send confirmation requests each fall before year-end workloads pile up.
Start your W-9 collection process today, even if it's already December. Every form you collect now is one less fire to put out in January whenundefineddeadlines loom. For teams managing ongoing contractor relationships, consider moving to an automated system that handles collection, validation, and filing in one workflow. Your January self will thank you.
