Plain English
When a company sends the IRS a group of 1042‑S statements for foreign recipients, it must also send a 1042‑T that says how many statements are in the batch and the total dollars reported. Think of it as the cover sheet for the whole package.

What this form is for
- Use when you are filing a batch of 1042‑S statements.
- Do not use for a single 1042‑S filed on paper; the paper 1042‑S includes its own transmittal.
- If you are filing 1042‑S for a calendar‑year that ends in a different fiscal year, check the 1042‑S instructions.
