Request for Taxpayer Identification Number and Certification

What the Request for Taxpayer Identification Number and Certification Is

The Request for Taxpayer Identification Number and Certification, commonly issued using IRS Form W-9, is a payer's request that a payee provide a taxpayer identification number (TIN) and certify certain tax classifications and exemptions. It is used by businesses and payers to collect accurate payee information for informational returns such as Form 1099. The form documents the name, business name if any, federal tax classification, address, TIN, and a signature certifying correctness and backup-withholding status. The form is not filed with the IRS by the payee; it is retained by the requester.

Why a Clear Request Matters for Tax Reporting

A complete, accurate Request for Taxpayer Identification Number and Certification reduces withholding errors, supports correct 1099 reporting, and limits payer exposure to backup withholding and IRS penalties. Properly collected W-9 data helps organizations meet information-reporting obligations under the Internal Revenue Code and maintain defensible audit records.

Why a Clear Request Matters for Tax Reporting

Who Issues and Completes This Request

Typical issuers include employers, financial institutions, gig platforms, and companies making reportable payments; recipients are independent contractors, vendors, and certain entities.

  • Payers: businesses and platforms that need payee TINs for Form 1099 reporting and backup-withholding determinations.
  • Payees: independent contractors, freelancers, LLCs, trusts, and other payees who must provide legal name and TIN to avoid withholding.
  • Advisors: payroll teams, accounts payable, and tax professionals who collect, verify, and store completed requests.

Collecting the form early in a vendor relationship reduces delays in payments and reporting while simplifying year-end tax workflows.

Timing and Deadlines Related to W-9 and Information Returns

Key dates affect when payers must use W-9 data and file associated informational returns; payees should provide completed requests promptly upon payer request.

W-9 Provision:

Provide the form when requested by the payer; no IRS filing deadline for the payee

1099-NEC Deadline:

Payers must furnish recipient and IRS copies by Jan 31 each year

1099-MISC Deadlines:

Recipient delivery by Jan 31; paper IRS filing by Feb 28; electronic by Mar 31

Backup Withholding Trigger:

Incorrect or missing TIN can initiate 24% backup withholding

Form Updates:

If name or TIN changes, supply a new form promptly to avoid reporting errors

Penalties and Key Risks of Incorrect Requests

Backup Withholding: 24% applied by payer
Incorrect Information Returns: IRC §6721 penalties may apply
Intentional Disregard: $660+ per form, no cap
I-9 Penalties: Separate civil penalties for I-9 violations
Payment Delays: Payers may withhold payments pending corrected W-9
Audit Exposure: Insufficient records increase IRS audit risk

Common Preparation Errors to Avoid

  • Providing a TIN that does not match the legal name on file with the IRS, which leads to IRS mismatch notices and potential backup withholding.
  • Using an incorrect entity type or failing to indicate a disregarded entity or LLC classification, causing misreporting on informational returns.
  • Leaving the signature or date blank, or signing with initials only; unsigned forms cannot be relied upon by payers for certification.
  • Failing to update the request when the payee’s name, address, or TIN changes, leading to erroneous 1099 issuance and penalties.

Required Data Elements on the Request

Legal Name: Payee's full legal name
Business Name: DBA or entity name if applicable
Federal Classification: Entity type selected
TIN: SSN or EIN provided
Address: Street, city, state, ZIP
