What changes when you move from Illinois to Puerto Rico
Illinois has a flat 4.95% income tax and Puerto Rico has graduated income tax rates up to 33%. On a $100,000 salary a single filer pays $4,805 in state income tax in Illinois and $18,382 in Puerto Rico income tax in Puerto Rico. Because Puerto Rico-source wages of bona fide Puerto Rico residents are excluded from IRS federal income tax under IRC §933 (while FICA still applies), total income and payroll tax rises by $406 a year after the move. HUD's one-bedroom Fair Market Rent averages $1,053 a month across Illinois's metro areas and $504 across Puerto Rico's (-52.1%). Pay differs too: the BLS median wage across all occupations, weighted by employment in each state's metros, is $54,104 in Illinois and $28,678 in Puerto Rico. City and county income taxes, which some localities add, are not included in these state-level figures; the metro routes below include them.
