Quarterly payroll filing only
Same purpose for quarterly returns

Annual unemployment tax filing

Non‑electronic filing
No e‑file signature needed
✓ Use only for mailed returns
The signature authorization must be submitted with the electronic employment‑tax return before the return’s filing deadline (e.g., the last day of the month following the quarter for Form 941). Late submission results in a rejected return and possible penalties.
