Is this multi-state tax withholding calculator free?

Yes. WithholdRight is 100% free with no signup, no email, and no paywall. We fund the site through display advertising so the tool stays open to everyone.

Which states does the calculator support?

All 50 U.S. states plus the District of Columbia. Tax rates, brackets, standard deductions, reciprocity agreements, and the convenience-of-employer rule are all built in for tax year 2025.

Does the calculator handle state tax reciprocity?

Yes. The calculator automatically detects when your residence and work state have a reciprocity agreement (16 states and DC participate in 30 such agreements) and applies the exemption. It tells you which exemption form to file with your employer.

What is the convenience of the employer rule and does the calculator handle it?

The convenience rule lets 8 states (AL, CT, DE, NE, NJ, NY, OR, PA) tax non-resident remote workers when telework is for the employee's convenience. The calculator applies this rule automatically when you select "remote work for employee convenience" as your work arrangement.

Can I trust the results for tax filing?

Our calculator uses data sourced directly from IRS Rev. Proc. 2024-40, SSA.gov, and each state Department of Revenue. Every figure is reviewed by a credentialed CPA before publication. However, no calculator replaces a licensed tax professional for your specific situation.
