Questions

Marginal rate or effective rate?

Marginal is the rate on your next dollar; effective is what you actually paid as a share of gross. The state pages rank by effective rate because that is the comparable number.

What counts as gross salary?

Everything paid before deductions: base pay, overtime, bonus and taxable benefits. Take-home is what remains after federal tax, FICA and state tax.

Is FICA the same in every state?

Yes. Social Security (6.2% up to the annual wage cap) and Medicare (1.45%) are federal, so they do not change when you move — only state income tax does.

Where can I check a definition against real numbers?

Open any salary or state page: each one shows the same definitions applied to a real paycheque, computed by the engine used site-wide.
