Where you withhold income tax
As a rule, you withhold for the state where the work is performed — which, for a remote employee, is where they sit, not where you are.
Multi-State PayrollTax Compliance
When an employee works in another state — including a remote employee — you can trigger that state's registration, withholding, and unemployment tax. We set it up right everywhere your team works.

The short version
- When you have an employee working in another state — including a remote employee — you may trigger that state's payroll registration, withholding, unemployment tax, and reporting requirements.
- The rules differ by state: where you withhold, where you pay unemployment tax, reciprocity agreements, and "convenience of the employer" rules can all change the answer.
- Alexander Accountants register you in each state and run payroll so it's right everywhere your team works.
Multi-state payroll compliance usually arrives with your first out-of-state remote hire, and it's easy to get wrong because every state writes its own rules.
An employee performing work in another state generally creates two obligations there: income tax withholding and state unemployment tax. With remote work, that means the state where the employee sits — which is often not where your business is based.
What changes the answer
02
Where you pay unemployment (SUTA)
Unemployment tax goes to one state per employee, set by where the work is based rather than where your business is registered.
03
Reciprocity agreements
Agreements between neighboring states can change which state you withhold for, so a border-state hire is not always what it seems.
04
"Convenience of the employer" rules
Some states can tax a remote employee’s wages even when the work is performed elsewhere — putting them on the hook in two states at once.
What you do in each state
- 1
Register in the state
Sign up with the state's tax agency for withholding and its labor agency for unemployment.
- 2
Set up accounts & rates
Open the withholding and unemployment accounts and load the rates the state assigns you.
- 3
File, remit, and report
Payments go out on each state's schedule, with the correct year-end forms filed everywhere you owe.

What multi-state payroll costs
Cost depends on how many states your team works in and how many employees you run. We map your states first, then quote it up front — before any registration begins.
Where multi-state payroll goes wrong
With remote teams, the failure modes are predictable — and avoidable when you set things up before the first payroll runs.
Two states
Double withholding
"Convenience of the employer" rules can put one remote employee on the hook in two states at once.
Missed registration
A remote hire creates obligations from day one — unregistered payroll turns into back taxes and penalties.
Wrong SUTA state
Paying unemployment tax to the wrong state means re-filing and paying twice while you sort it out.
This fits if…
- You have hired — or are about to hire — a remote employee in another state.
- Your team works across multiple states.
- You've had employees relocate and aren't sure where to withhold now.
- You have received a notice from a state tax or labor agency.
With remote teams, multi-state payroll is a question of when, not if. Setting it up right with the first out-of-state hire is far cheaper than untangling missed registrations years later.
Get multi-state payroll right
Tell us where your employees actually work and where your business is registered, and we'll map the states you owe and set up compliant payroll.
Most multi-state payroll problems begin quietly, with one remote employee working from a different state. The best time to address withholding and unemployment registration is before the first payroll is run, not after the notices arrive.
