Form Overview

IRS Form W3C - W-3C

Form W‑3C is the transmittal sheet that summarizes wage and tax statements (Form 1042‑S) sent to the IRS for certain foreign persons. File it when you submit a batch of 1042‑S forms.

It captures the total number of 1042‑S forms, total wages, total tax withheld, and the payer’s identifying information.

Risk Radar

Scan points
  • 1A single typo in the total tax withheld can cause the entire batch to be rejected.
  • 2Totals on W‑3C do not equal the sum of the 1042‑S forms
  • 3Incorrect EIN or payer name
  • 4Missing signature or date
  • 5Using the wrong edition of the form

Plain English

Think of the W‑3C as a cover page that tells the IRS the total amounts you reported on all the 1042‑S forms you’re sending. It’s required only for foreign‑person reporting and must match the details on each individual 1042‑S.

Submission Date

  • Filing date: 2024-06-26 22:10:13
  • Preparation window: collect IDs, supporting records, and signatures in advance.
  • Final review: verify names, dates, and required fields before submission.
