Common questions about registering for payroll taxes.
Yes- if you have employees working in your state, you are required to register with the appropriate state tax agencies before running your first payroll. Failing to register can result in penalties and back taxes.
Wisconsin employers register for withholding through the Wisconsin Department of Revenue's My Tax Account portal. UI registration is handled separately through the Department of Workforce Development. We complete both registrations on your behalf and ensure your payroll system is configured for Wisconsin's current withholding tables.
