Massachusetts Tax Overview for 1099 Workers

Massachusetts charges a flat 5% income tax rate on most income, with a 9% surtax on income above $1,083,150 (the "millionaires tax" passed in 2022). For the vast majority of earners, Massachusetts is effectively a flat 5% state — which is lower than many people assume given Massachusetts' reputation as "Taxachusetts." There is no Massachusetts standard deduction, but there are personal exemptions and various credits. Massachusetts has no local city income taxes. Compared to neighboring Rhode Island (3.75-5.99%), Connecticut (2-6.99%), and New Hampshire (no income tax), Massachusetts sits in the middle for most income levels. The high cost of living — especially in the Boston metro — means the overall affordability picture is more complex than the tax rate alone suggests.
