A take-home, tax, and retirement calculator built for merchant mariners paid by the day. Plug in your rate and your hitch, and see where every dollar lands.
46 U.S.C. § 11108 — if you perform regularly-assigned duties on a vessel operating in interstate or foreign trade (navigable waters of more than one state), only your state of legal residence may tax your sea wages — not the states whose ports or waters you transit. This is why many mariners domicile in a no-income-tax state. Pick your residence below, not where the boat runs. Income earned entirely within one state's waters can still be taxed by that state.
