Indiana Salary & Paycheck Calculator 2026

Withholding on an Indiana paycheck flows through Form WH-4, the state's combined state-and-county withholding certificate. Indiana is the only US state where every single county imposes a local income tax — Marion (Indianapolis) at 2.02%, Hamilton (Carmel / Fishers) at 1.10%, Allen (Fort Wayne) at 1.59%, Lake (Gary / Hammond) at 1.50%, all 92 counties charge something. The county rate is determined by your county of RESIDENCE on January 1, not your employer's location, and it stays your county-of-record for the entire tax year regardless of mid-year moves. New hires and moves both require updating WH-4 to ensure correct county allocation.

Take-home math at three tiers, Indiana Marion County (Indianapolis) single filer 2026: $60,000 → about $5,020 federal + $4,590 FICA + $1,741 IN state + $1,192 county = $12,543 deductions, take-home $47,457 (79%). $100,000 → $13,170 federal + $7,650 FICA + $2,921 IN + $2,000 county = $25,741, take-home $74,259 (74%). $150,000 → $24,734 federal + $11,475 FICA + $4,396 IN + $3,010 county = $43,615, take-home $106,385 (71%). County tax rides the same exemption-reduced base as the state tax, not gross wages — Departmental Notice #1's withholding example computes both from one figure. A Hamilton County worker (Carmel / Fishers / Westfield) pays only 1.10% county versus Marion's 2.02% — saving roughly $911/year at $100K just by living north of the Marion County line.

Indiana's flat 2.95% state rate is on a multi-year schedule down to 2.90% by 2027 (HB 1002, 2022). The county layer is the bigger variable: 2026 county rates run from 0.5% (Porter) to 3.0% (Randolph), and the counties around Indianapolis are not uniformly cheap: Hamilton charges 1.10%, Johnson 1.40%, Hendricks, Boone and Shelby 1.70%, Hancock 1.94% and Morgan 2.72%. Indiana doesn't use a federal-style standard deduction — the personal exemption ($1,000 per filer, plus $1,000 per dependent and an additional $1,500 per dependent child) is the only state-level deduction analog, which means Indiana taxable income runs about $15,000 higher than federal taxable income for a single filer. Property tax averages ~0.84% effective. The state has no estate or inheritance tax (eliminated in 2013).

The single highest-leverage tactic for Indiana W-2 earners is residence selection within the metro: a Hamilton County address versus Marion saves roughly $911/year at $100K and $1,371/year at $150K, with no impact on Indianapolis-area employer access (Carmel and Fishers are direct commutes from downtown). Maxing pre-tax 401(k) and HSA also reduces both state AND county taxable wages, since Indiana counties follow the same federal-conforming pre-tax rules as the state. A $24,500 401(k) deferral in Marion County saves about $1,218 combined state + county tax per year — meaningful at the 5% combined marginal rate.
