Form W-9 Rev. December 2014 IRS
Use a W9 Form template to make your document workflow more streamlined.
What Form W-9 is and how it works
Form W-9, Request for Taxpayer Identification Number and Certification, is provided by a U.S. payee to a requester that needs accurate taxpayer information for payment reporting. The payee supplies a legal name, business name when applicable, federal tax classification, address, exemptions, and taxpayer identification number, then signs the certification. The requester generally keeps the form rather than sending it to the IRS. A W-9 has no filing deadline; it is provided upon request, including before reportable payments.
Who uses Form W-9
Payers and accounts-payable teams
Payers request W-9 forms from independent contractors, vendors, landlords, and other payees before making reportable payments and preparing information returns.
U.S. payees and contractors
Businesses and individuals receiving reportable payments provide their legal name, tax classification, address, and taxpayer identification number on the W-9.
Businesses that rely on W-9 collection
Form W-9 supports payment onboarding for independent contractors, property payees, vendors, and organizations preparing IRS information returns.
Solo consultants use Form W-9 to provide their legal name and TIN before receiving reportable service payments from business clients. Property owners and landlords provide W-9 information to payers that need accurate records for rent-related information reporting. Large procurement teams collect W-9 forms from vendors, validate submitted details, and preserve records for recurring payment and reporting processes.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
How Form W-9 works
Form W-9 lets a U.S. payee give a requester the taxpayer information needed for payment reporting and withholding decisions.
Request the form: The payer requests Form W-9 from a U.S. payee before reportable payments. Provide taxpayer details: The payee enters legal name, tax classification, address, and TIN. Certify the information: The payee signs the certification under penalty of perjury. Support tax reporting: The payer uses the information for withholding and information reporting.

W-9 completion challenges to avoid
Entering an incorrect taxpayer identification number can cause backup withholding, reporting errors, or delays resolving payer verification questions. Leaving the federal tax classification or exemption fields blank can make the W-9 incomplete for the requesting payer. Sending an unprotected W-9 can expose a Social Security number or employer identification number to unauthorized recipients. Using an outdated address can prevent the payer from maintaining accurate records for future information reporting.

Legal value of an electronic W-9
An electronically signed W-9 can support attribution, intent, and record reproducibility under ESIGN, 15 U.S.C. ch. 96, and applicable UETA law. The W-9 remains a tax-information record, not an IRS filing. ESIGN exceptions include wills, codicils, certain court filings, and family-law decrees, which are outside this form’s purpose.
W-9 questions and troubleshooting
Resolve W-9 collection issues by checking the IRS purpose, taxpayer fields, signer evidence, and signNow record controls.
Upload the IRS W-9 PDF to signNow, run field detection, then inspect every field manually. Confirm the taxpayer name, address, classification, TIN, and certification fields before sending because automatic detection does not validate tax accuracy.
A W-9 is normally provided to the requester, not filed with the IRS. Use signNow to collect the signed record, then retain it with payment documentation. IRS information-return reporting remains the payer’s responsibility under applicable IRS instructions.
There is no general W-9 filing deadline. Request the form before making reportable payments or preparing information returns. signNow can send an email invitation or signing link, while the payer controls its own collection schedule.
Use signNow’s audit trail and completion certificate to document delivery, signer activity, timestamps, and finalization. ESIGN and UETA recognize electronic signatures when intent, attribution, consent, and reproducible records are established.
Business includes audit trails, templates, and mobile apps at $8 per user monthly when billed annually. Business Premium is $15 and adds bulk send. Select the plan based on volume and controls required for W-9 collection.
Treat the SSN or EIN as sensitive taxpayer information. Restrict access, use encrypted transmission and storage, export the audit trail with the final PDF, and apply the IRS retention period under IRC §6501(a).
