Quick answer

Yes, but barely. Porter County levies a 0.5% county income tax, by far the lowest of Indiana's 92 counties. At $85,000 single, a Porter County resident takes home $65,725 after federal tax, FICA, Indiana's flat state tax, and a county line of just $425.

Porter County sits on Lake Michigan between Gary and the Michigan line, taking in Valparaiso, Portage and the Indiana Dunes. Its county income tax is 0.5%, and that number is remarkable in context: every one of Indiana's 92 counties levies a local income tax, most of them charge several times this rate, and Porter's is the lowest in the state by a wide margin. Neighbouring Lake County charges roughly three times as much on the same income, which makes the county line between them one of the sharpest local-tax borders in the Midwest. Indiana's county tax follows residence rather than workplace, so a Porter County resident commuting to a job in Lake County, or into Chicago, still pays only Porter's rate. That combination, a Chicago-commutable location with the lowest county tax in Indiana, is the county's defining paycheck fact. The Dunes national park and the Portage lakefront steel works bracket its geography. At $85,000 single, federal tax is $9,870, Indiana state tax $2,478, FICA $6,503, and the Porter County line $425, leaving $65,725.

Porter County, Indiana paycheck FAQ

Is Porter County really the lowest county tax in Indiana?

Yes, by a clear margin. All 92 Indiana counties levy a local income tax, and Porter's 0.5% is the smallest of them. Most Indiana counties charge multiples of it, so a Porter resident keeps meaningfully more of the same gross than a resident of almost anywhere else in the state.

I live in Porter County and work in Lake County. Which rate applies?

Porter's 0.5%. Indiana's county income tax is determined by your county of RESIDENCE on 1 January, not by where you work, so a Porter resident commuting to a Lake County job pays Porter's much lower rate on those wages. The reverse commute is expensive.

What if I live in Porter County and work in Illinois?

Indiana and Illinois have a reciprocity agreement for wage income, so an Illinois-earned wage is taxed by Indiana rather than Illinois. Your Indiana state tax and the Porter County 0.5% both apply, which keeps the Chicago-commuter arithmetic unusually favourable from this county.

What is the federal tax bill on $85,000 single in Porter County?

Federal income tax at $85,000 single is $9,870, in the 22% bracket after the standard deduction. Indiana then applies a flat 2.95% state rate, and the county adds $425, which at Porter's rate is a very small line by Indiana standards.

Does a 401(k) contribution reduce the Porter County tax?

Yes. Indiana's county tax is computed on Indiana adjusted gross income, so a traditional 401(k) deferral reduces the state and county lines together, at a combined marginal rate near 24.95%. The county saving is small here simply because the rate is.

What changes for married filing jointly at $85,000 in Porter County?

Joint filers take home about $69,784, roughly $4,060 more than single. Indiana's flat state rate and the flat county rate apply identically to every filing status, so the whole difference comes from federal brackets and the doubled standard deduction.
