Texas businesses with remote employees or operations in other states face a payroll challenge that most local providers cannot handle. Multi-state payroll requires registering in each work state, withholding the correct state income tax, and managing multiple unemployment insurance accounts. Here is what you need to know.
Why Multi-State Payroll Is More Complex Than Single-State
When an employee works in a state other than Texas, that state typically has income tax withholding obligations — even if your business is based in Texas. You must register for a withholding account in the employee’s work state, withhold state income tax using that state’s rates and forms, pay state unemployment insurance to the state where the employee works, and file quarterly returns with each state’s revenue and workforce agencies. Texas has no state income tax, which simplifies your Texas obligations, but you still must comply with every state where your employees actually work.
How to Determine Which States You Have Obligations In
Nexus — the legal connection that triggers state tax obligations — is created when an employee physically performs work in a state. A Texas employee who works remotely from Colorado for one month creates Colorado nexus. A salesperson who regularly visits clients in Oklahoma creates Oklahoma nexus. Even occasional business travel can trigger obligations in some states. Audit your employee locations at least quarterly and register in new states before payroll runs there.
Registering for Payroll Tax Accounts in Multiple States
- Obtain a Federal Employer Identification Number (FEIN) if you do not already have one
- Register with the state Department of Revenue or Taxation for income tax withholding
- Register with the state Workforce or Labor agency for unemployment insurance
- Obtain account numbers for each state — they are required on all quarterly filings
- Note that registration timelines vary — some states process in days, others in weeks
Payroll Tax Calculations for Multi-State Employees
Withhold the income tax of the state where the employee physically works. If an employee works in multiple states in a pay period, apportion withholding based on time spent in each state. Pay state unemployment insurance to the state where the employee works primarily or where employment began. Reciprocal agreements between some states allow employees to pay income tax only in their home state — Texas has no reciprocal agreements, but employees in other states may qualify based on their home state’s rules.
Staying Compliant Across Multiple States
Review state-specific minimum wage, overtime, and paid leave laws for each state where you have employees — they often differ significantly from Texas and federal standards. File quarterly returns and remit payments to each state agency by its deadline. Maintain separate payroll records that track wages and withholdings by state. Update registrations promptly when employees move to new states or stop working in a state.
