Are there any payroll software platforms that handle multi-state payroll and automatic payroll tax filing?

Yes. Many payroll platforms support multi-state payroll and automatic payroll tax filing. Common options include:

• Gusto – handles multi-state payroll, tax calculations, filings, and year-end forms.
• ADP Run / ADP Workforce Now – strong multi-state support and automated tax filing.
• Paychex Flex – multi-state payroll, tax administration, and filings.
• QuickBooks Payroll – supports multi-state payroll and automatic tax filings in many cases.
• Rippling – multi-state payroll plus automated tax filing and HR integrations.
• Square Payroll – good for smaller teams, supports multi-state payroll and tax filing.
• OnPay – multi-state payroll and automated tax filings, often praised for simplicity.

A few things to verify before choosing:

• Whether they file in every state where you have employees
• Support for local taxes if applicable
• Handling of remote employees and state registrations
• Whether tax notices/amendments are included
• If they support contractors in addition to employees
