One filing or the whole year. We ask for what we need by email, well before each date.
What Atlas set up, and what stays with you
Atlas forms the company. The yearly filings belong to the company and its owner, whoever formed it.

W-8BEN, not W-9, for most Atlas LLC owners
Stripe, clients and platforms ask for a tax form before they pay you. Which one depends on who owns the company and how it is taxed.
What is the company, and who owns it?
Single-member LLC, owned by you
W‑8BEN
The IRS looks through the LLC to you, so you give Form W‑8BEN in your own name, as a non-US person. A W‑9 is for US persons.
C‑Corp
W‑9
A C‑Corp is its own US taxpayer. It gives Form W‑9 in its own name, with its EIN.
A company, or several people
It depends
The answer changes with the owners. The guide walks through each case.
W-9, W-8BEN or W-8BEN-E?
Where the form goes. To the payer that asked, through its own form or by email. It is not filed with the IRS.
Hand over the yearly filings
Add your Atlas company to Nonresident Tax, then choose what we take on. Formed elsewhere is fine: choose “I already have a US company” when you sign up.
