W-9 Collection Checklist

Collecting W-9 forms from vendors and contractors is a critical compliance requirement. This comprehensive checklist ensures you gather all necessary information securely and efficiently.

Before You Start

Before requesting W-9 forms, make sure you have:

• [ ] A secure system for collecting and storing forms
• [ ] Clear communication templates for vendors
• [ ] A tracking system to monitor compliance
• [ ] Understanding of IRS backup withholding requirements

Initial Vendor Setup

1. Identify Which Vendors Need W-9s

You need a W-9 from any vendor or contractor who:

• [ ] Will receive $600 or more in payments during the year
• [ ] Provides services (not just selling goods)
• [ ] Is a U.S. person or entity
• [ ] Needs to be reported on Form 1099-NEC or 1099-MISC

2. Request W-9 Before First Payment

Best practice is to collect W-9s before making any payments:

• [ ] Send W-9 request with vendor onboarding materials
• [ ] Set a deadline for submission (typically 7-14 days)
• [ ] Include clear instructions on how to submit
• [ ] Explain why the form is needed

W-9 Form Review Checklist

When you receive a completed W-9, verify these critical fields:

Required Information

• [ ] Name matches business legal name
• [ ] Business name (if different from legal name)
• [ ] Federal tax classification is checked
• [ ] Address is complete and accurate
• [ ] TIN (SSN or EIN) is provided and complete
• [ ] Signature is present and dated
• [ ] Date is within the last 3 years

Common Red Flags

Watch for these issues that require follow-up:

• [ ] Missing or incomplete TIN
• [ ] Unsigned form
• [ ] Name mismatch with payment records
• [ ] P.O. Box without street address
• [ ] Form older than 3 years

Security & Storage

Secure Collection

• [ ] Use encrypted transmission methods (never email unencrypted)
• [ ] Implement access controls for form storage
• [ ] Maintain audit trail of who accessed forms
• [ ] Use secure cloud storage with encryption at rest

Retention Requirements

• [ ] Store forms for at least 4 years after last payment
• [ ] Keep digital backups in secure location
• [ ] Implement document retention policy
• [ ] Plan for secure disposal after retention period

Vendor Follow-Up

Missing or Incomplete Forms

If a vendor doesn't submit or completes the form incorrectly:

• [ ] Send reminder within 3 business days
• [ ] Escalate to management after 7 days
• [ ] Consider backup withholding if no response after 15 days
• [ ] Document all follow-up attempts

Annual Updates

• [ ] Request updated W-9s every 3 years
• [ ] Update immediately if vendor information changes
• [ ] Verify TIN matches IRS records periodically
• [ ] Maintain version history of all W-9s

Backup Withholding Compliance

You must withhold 24% from payments if:

• [ ] Vendor doesn't provide TIN
• [ ] IRS notifies you of incorrect TIN
• [ ] Vendor fails to certify they're not subject to backup withholding

Year-End Reporting Preparation

Before December 31st each year:

• [ ] Verify all active vendors have current W-9s
• [ ] Reconcile payment records with W-9 information
• [ ] Identify vendors requiring 1099 forms
• [ ] Prepare 1099-NEC forms for filing by January 31st

Best Practices

Communication Templates

Create standard templates for:

• [ ] Initial W-9 request email
• [ ] Follow-up reminders
• [ ] Annual update requests
• [ ] Vendor onboarding packets

Process Documentation

Maintain clear documentation of:

• [ ] W-9 collection procedures
• [ ] Roles and responsibilities
• [ ] Escalation procedures
• [ ] Security protocols

Regular Audits

• [ ] Quarterly review of W-9 compliance status
• [ ] Annual audit of security controls
• [ ] Periodic testing of backup withholding procedures
• [ ] Regular training for staff handling W-9s

Common Mistakes to Avoid

1. Waiting until year-end to collect W-9s
2. Accepting incomplete forms without follow-up
3. Storing forms insecurely (email, shared drives without encryption)
4. Not validating TINs against IRS records
5. Ignoring backup withholding requirements
