The problem
Remote work broke payroll tax. Most calculators didn't catch up.
When you live in Virginia and your employer is in Maryland, who withholds what? What about a New York employer and a Florida home? The major paycheck calculators still treat "where is the office?" as the only question. They miss reciprocity, the convenience rule, SUI localization, and local taxes — and you pay for it at filing time.
Wrong state SUI
Most calculators assume SUI follows the work state. The American Payroll Association four-factor test often points elsewhere — and getting it wrong triggers audits.
Missed reciprocity
Sixteen states and DC have reciprocity agreements. If your employer does not honor them, you over-withhold by thousands per year and wait for a refund.
Convenience rule trap
Eight states tax non-resident remote workers when telework is "for convenience." Generic calculators miss this entirely, leaving you under-withheld and penalized.
