Form 1099-NEC Deadline
STRICT JANUARY 31 DEADLINE. Must be sent to contractors and filed with the IRS for all non-employee payments of $600 or more.

Does Form W-9 Expire? Expiration & Renewal Rules
A common question among freelancers and payroll departments is whether W-9 forms must be re-signed every year:
Official IRS Expiration Rule:
Form W-9 does NOT expire annually. A completed and signed Form W-9 remains valid for as long as the payee provides services to the client, UNLESS the payee legal name, business tax classification, address, or Taxpayer Identification Number (SSN/EIN) changes. If any tax detail changes, a new W-9 must be submitted immediately.
IRS Late Penalties & 24% Backup Withholding Math
Failing to collect W-9 forms or missing the January 31 1099-NEC deadline triggers severe financial consequences:
24% Backup Withholding
If a contractor refuses to provide a W-9, IRC § 3406 mandates withholding 24% of all gross invoice payments and remitting it directly to the IRS.
Tier 1: $60 / Form Penalty
Filing 1099-NEC forms up to 30 days after the January 31 deadline.
Tier 3: $310 / Form Penalty
Filing 1099-NEC forms after August 1 or failing to file completely.
$630+ Intentional Disregard
Intentionally failing to file 1099s results in a penalty of $630+ per form with NO maximum cap.
