State tax filing coverage

What gets filed in each state

For every state where the client has employees, three categories of state filings are recurring: the state income tax withholding return (typically quarterly), the state unemployment insurance (SUI) wage report (quarterly), and any paid-family-medical-leave or state-disability returns the state administers. Annual state W-2 and 1099 transmittals are filed where the state requires them separately from the federal filing.

How returns reach the state

States offer different channels. Some accept direct electronic file under a TPA (third-party administrator) relationship; we transmit straight from Payrollix. Others require a bulk upload to a state portal that Payrollix authenticates into; the upload happens on our infrastructure. A small set still requires a manually routed file that we generate and submit.

You do not need to know which mechanism a given state uses. Each state's return appears on the same tax-filings list with status and acknowledgment, regardless of the underlying channel.

State registration is still on the client

Payrollix does not register a client with a new state. The client has to be enrolled with the state's tax and unemployment agencies before any return can be filed there — we file under the client's state IDs, not on top of them.

When a client adds an employee in a new state, the state IDs need to be on the record before the first affected payroll. Some state registrations take days; some take weeks. We can point at the right state forms and walk through the process, but the client (or you on the client's behalf) is the one filling them out.

Multi-state employees

Employees who work in more than one state during the year produce withholding and unemployment liability in multiple states, and the returns reflect that. Allocation is handled per pay period based on the work location designated for each set of hours, and the resulting state returns are filed in each affected state.
