Running the same through different state assumptions shows how much of the difference is state income tax. Federal tax and payroll taxes apply everywhere, so the comparison is really about the state layer, and these are flat-rate estimates, not residency or sourcing determinations.

Why this happens

States differ widely: some have no wage income tax, others have high graduated rates.

Federal income tax and payroll taxes apply regardless of state.

A simple comparison uses flat effective rates, which approximate but do not replace full bracket math.

Which state can actually tax a depends on residency and where you worked, not just a rate table.

What to check

  • Which states you are comparing and whether they tax wages.
  • That federal and payroll taxes are the same across the comparison.
  • Whether the estimate uses flat rates or full brackets.
  • Local taxes that some cities add on top of state tax.
  • That a comparison is not a sourcing determination for a real move.

Common mistake

Reading a state comparison as a ruling on which state will tax your . It estimates the rate difference; actual sourcing depends on residency, work location, and timing.

Example scenario (hypothetical)

Illustration only, not your tax situation.

Example: the same $50,000 is compared in a no-income-tax state and a high-tax state. The federal and payroll portions match; the state line is where they diverge, but a real move's tax depends on the facts.

When to get help from a tax pro

  • You are weighing a real move between states.
  • Local taxes may apply where you live.
  • Your residency or work location is split.
  • You want full bracket math, not a flat estimate.
