Where you are

You live in Clay County, Illinois. 13,248 people live here with you. The population shrank 0.6% last year, and more Americans moved out than in (net -58).

Illinois exempts all retirement income from its flat 4.95% income tax: Social Security, pensions, 401(k) and IRA withdrawals are untaxed. It offsets that with the second-highest property taxes in the country and an estate tax that starts at $4 million, well below the federal threshold. Chicago and the collar counties hold two-thirds of the population; downstate is a different housing market.
