You've sent three polite emails. You've left a voicemail. Your vendor cashed your check two weeks ago but still hasn't sent back the W-9 form you need to file their 1099. It's mid-January, the IRS deadline is breathing down your neck, and you're stuck playing accounts payable detective instead of doing actual work.
To request a W-9 from a vendor effectively: send a clear, specific email explaining what you need and why, include the form or a link to complete it, set a reasonable deadline (7-10 business days), and follow up systematically if they don't respond. The key is removing friction from the process while making it clear this isn't optional—it's a tax compliance requirement that protects both parties.
Here's how to handle the entire W-9 collection process without the awkwardness, the endless back-and-forth, or the last-minute scramble.
Why Vendors Ignore W-9 Requests (And How to Fix It)
Most vendors aren't deliberately difficult. They're overwhelmed, disorganized, or genuinely don't understand what you're asking for. Understanding the common roadblocks helps you craft a request they'll actually respond to.
Common reasons vendors don't return W-9 forms:
- They don't know what a W-9 is or why it matters
- Your email got buried in their inbox
- The process feels complicated or time-consuming
- They're concerned about sharing their Social Security Number or EIN
- They've already submitted one to you (maybe years ago) and think it's still valid
- No one made it clear this is mandatory
The solution isn't to send the exact same email again, louder. It's to anticipate these objections in your initial outreach and make compliance the path of least resistance.
The Best Time to Request a W-9 From a Vendor
Don't wait until tax season. The absolute best time to collect a W-9 is before you issue the first payment. Build it into your vendor onboarding workflow, right alongside your payment terms and vendor agreement.
When you request W-9 forms at onboarding:
- Vendors expect paperwork and are in "getting set up" mode
- You have maximum leverage (they want to get paid)
- You avoid the January panic when everyone else is also chasing forms
- You create a complete file from day one
If you've already been working with a vendor, the second-best time is right now. The IRS requires you to request an updated W-9 if a vendor's name or TIN changes, but it's smart practice to refresh W-9 forms every 3-4 years regardless.
The W-9 Request Email Template That Actually Works
Here's a template you can adapt. It's direct, explains the why, and removes friction:
Subject: W-9 Form Needed for [Vendor Company Name] – Action Required
Hi [Name],
We need a completed W-9 form from [Vendor Company Name] for our tax records. We're required to collect this from all vendors we pay more than $600 per year.
What you need to do: [Option 1: Fill out the attached W-9 form and return it to this email] [Option 2: Complete your W-9 online here: [secure link]]
Deadline: [Specific date, 7-10 business days out]
The W-9 provides your business name, address, and Tax ID number. We use this information to file IRS Form 1099-NEC at year-end. You won't owe any additional taxes because of this form—it's simply reporting what we've already paid you.
Privacy note: We keep this information secure and only use it for tax reporting purposes.
If you have questions or concerns, just reply to this email. Otherwise, please submit by [date] so we can keep your account current.
Thanks, [Your name] [Title] [Company]
Why this template works:
- Clear subject line with "Action Required"
- Explains what, why, and by when in the first two sentences
- Offers easy completion options
- Addresses the privacy concern upfront
- Sets a specific deadline
- Professional but not overly formal
How to Follow Up When Vendors Don't Respond
Even the perfect email won't get a 100% response rate. Here's a systematic follow-up sequence:
First Follow-Up (2-3 days before deadline)
Subject: Reminder: W-9 form needed by [date]
Quick reminder that we need your completed W-9 by [date]. I've attached the form again for convenience.
Let me know if you have any questions or need help completing it.
Second Follow-Up (1 day after missed deadline)
Subject: W-9 form still needed for [Vendor Company Name]
Hi [Name],
We still need your W-9 form to keep your vendor account compliant. This is required by the IRS for tax reporting.
Can you send this back by end of day [new date, 3-5 days out]? If there's an issue preventing you from submitting, please let me know so we can resolve it.
Third Follow-Up (If absolutely necessary)
At this point, escalate the tone slightly and introduce consequences:
We're required by law to collect W-9 forms from all vendors before processing payment. We may need to pause future payments until we receive your completed form. Additionally, IRS regulations require us to begin backup withholding at 24% if we don't have valid taxpayer information on file.
This usually gets immediate action because it affects their cash flow.
What to Do When Vendors Refuse or Give Pushback
Some vendors will say they "don't give out that information" or claim they've never had to provide a W-9 before. Here's how to handle common objections:
"I don't feel comfortable sharing my Social Security Number"
Response: "I understand the concern. The W-9 stays in our secure files and is only used for tax reporting. The IRS requires us to collect this information from vendors we pay over $600 annually. If you operate as a business, you can provide your EIN instead of your SSN."
"I've never had to do this with other clients"
Response: "Any business that pays you more than $600 in a year is required to collect this form and issue a 1099. Some companies don't follow proper procedures, but we're required to comply with IRS regulations."
"Can't you just use the one I sent you three years ago?"
Response: "We do have your previous W-9 on file, but we're updating our records to ensure all information is current. This should only take you two minutes to complete."
If a vendor absolutely refuses and you've paid them $600 or more during the tax year, you're still required to file a 1099-NEC. You'll need to report using whatever information you have and potentially begin backup withholding at 24% on future payments.
Automating W-9 Collection So You Never Chase Again
If you're managing more than a handful of vendors, you shouldn't be manually emailing, tracking, and chasing W-9 forms. The accounts payable teams who've solved this problem have moved to automated collection systems.
Collect1099 handles the entire W-9 request and collection workflow automatically. You add your vendors, the system sends professional requests, follows up automatically, securely stores the completed forms, and pre-fills yourundefinedforms when it's time to file. No more spreadsheets, no more chasing, no more January panic.
The difference between chasing vendors manually and using purpose-built software is the difference between spending 20+ hours onundefinedprep and spendingundefinedminutes.
What Information You Actually Need From the W-9
When you receive a W-9 back, verify these critical fields are complete before filing it away:
- Name (Line 1): Must match the name on their tax return
- Business name (Line 2): If different from line 1
- Tax classification: Individual/sole proprietor, LLC, Corporation, etc. (This determines whichundefinedform you'll use)
- Address: Current mailing address
- Taxpayer Identification Number: Either SSN or EIN
- Signature and date: The form must be signed to be valid
Incomplete or unsigned W-9 forms are worthless for IRS purposes. Check them when they come in, not in January when the vendor is on vacation.
Setting Up a System That Works Long-Term
The best W-9 collection strategy is one you build into your standard operating procedures:
For new vendors:
- Make W-9 submission part of your vendor application process
- Don't issue first payment until you have a completed, verified W-9
- Store forms in a dedicated, secure location with controlled access
For existing vendors:
- Request updated W-9 forms if there's a name change, business structure change, or address change
- Do a bulk refresh every 3-4 years
- Set calendar reminders in October to verify you have current W-9s for all vendors who've crossed the $600 threshold
For your team:
- Document your W-9 request and follow-up process
- Create email templates everyone can use
- Assign one person to own vendor tax compliance
- Track response rates and follow-up status in a spreadsheet or software
The IRS can penalize you $290 per form (as ofundefinedrates, adjusted annually) for failing to file accurateundefinedforms, and those penalties increase if the failure is due to intentional disregard. Having a documented process shows good-faith compliance efforts.
Frequently Asked Questions
When should I request a W-9 from a vendor?
Request a W-9 before issuing the first payment to any new vendor, and collect updated forms every 3-4 years or whenever there's a business name or structure change. If you're already working with a vendor and don't have their W-9, request it immediately—don't wait until tax season when everyone else is also chasing forms and vendors are less responsive.
What if a vendor refuses to provide a W-9 form?
If you've paid a vendor $600 or more during the tax year and they refuse to provide a W-9, you're still required to file Form 1099-NEC using whatever information you have. You must also begin backup withholding at 24% on future payments. Document all your W-9 requests in case of an IRS audit—showing good-faith efforts to collect the form protects you from some penalties.
Can I use the same W-9 form for multiple years?
Yes, a W-9 form remains valid until the vendor's information changes. However, best practice is to request updated W-9 forms every 3-4 years to ensure accuracy. You must request a new W-9 immediately if the vendor changes their business name, business structure, or notifies you of a TIN change.
Do I need a W-9 from vendors I paid less thanundefineddollars?
Technically no—the IRS only requires 1099-NEC forms for vendors paid $600 or more in a calendar year. However, many businesses collect W-9 forms from all vendors at onboarding regardless of payment amount, because vendor relationships often grow over time and it's much easier to collect the form upfront than to chase it later if payments cross the threshold.
What is the penalty for not collecting W-9 forms from vendors?
The IRS can assess penalties of $290 per form (2024 rate) for failing to file accurateundefinedforms, with higher penalties for intentional disregard. If you don't have a vendor's correct TIN because you failed to request a W-9, you may also be required to begin backup withholding at 24% on future payments. Documented efforts to collect W-9 forms provide important audit protection.
Stop Chasing, Start Collecting
The awkwardness of requesting W-9 forms disappears when you treat it as standard business procedure rather than a special favor. Build it into your vendor onboarding, use clear communication that explains the why, make the process frictionless, and follow up systematically.
The vendors who've worked with professional organizations expect this. The ones who haven't will follow your lead if you're clear and confident. And the tiny percentage who push back will comply once they understand this isn't optional—it's how compliant businesses operate.
Your January self will thank you for building this system now, before the deadline pressure hits.
