Inside an Indiana Pay Stub: 2.95% State Plus County LIT

An Indiana paycheck shows federal income tax, FICA payroll taxes (Social Security at 6.2% on wages up to the cap, Medicare at 1.45% on all earnings plus the 0.9% high-earner surtax above $200,000), Indiana state income tax via Form WH-4, and the county Local Income Tax (LIT) for the county where the worker resides on January 1 of the tax year. Indiana is one of the few states with significant county-level income taxation, similar to Maryland and Pennsylvania.

Form WH-4 and the Personal Exemption

Indiana Form WH-4 governs state withholding alongside the federal W-4. Workers claim a personal exemption ($1,000 single, $2,000 joint) and an additional dependent exemption ($1,500 per dependent, plus $1,500 per qualifying child for federal CTC). The form also asks workers to identify their county of residence on January 1 — this determines which county LIT rate applies for the entire calendar year, even if the worker moves mid-year. Workers crossing state lines (working in Illinois or Kentucky while residing in Indiana) should file the Indiana WH-4 for state and county purposes, with the work-state employer withholding instead.

The Phase-Down: 3.40% to 2.95% to 2.9% to (Possibly) 2.55%

Indiana's flat tax has fallen substantially since 2022. The rate dropped from 3.23% (2022) to 3.15% (2023), 3.05% (2024), 3.00% (2025), and 2.95% effective January 1, 2026 per Indiana DOR guidance. The legislative path continues: HB 1001 (2023) sets the rate at 2.9% for 2027. SB 451 (April 2025) creates conditional triggers for additional 0.05% reductions in 0.05% increments in even-numbered years beginning January 1, 2030, potentially reaching 2.55% by 2032 if revenue thresholds are met. The trajectory makes Indiana one of the lowest flat-rate states in the country once the post-2030 triggers fire.

The County LIT Layer

Indiana's 92 counties each set their own LIT rate independently, with rates ranging from roughly 0.5% in low-rate counties (Newton, Pulaski, Warren) to 3.38% in Pulaski County and similar high-LIT counties. The LIT is structured as a single combined rate per county (versus Maryland's separate state and local layers) and is administered alongside state withholding through Form WH-4. Counties may adopt new LIT rates or modify existing rates; Marion County (Indianapolis) ran 2.02%, Hamilton County (Carmel/Fishers) 1.10%, Allen County (Fort Wayne) 1.59%, Hendricks 1.70%, Bartholomew (Columbus) 1.95%. Workers commuting from one county to another pay LIT based on residence on January 1 only.

2026 Federal Math at Indiana Wage Levels

The IRS 2026 inflation adjustments set the standard deduction at $16,100 single, $32,200 married filing jointly, and $24,150 head of household. Marginal federal brackets for single filers run 10% on the first $11,925, 12% to $48,475, 22% to $103,350, 24% to $197,300, continuing upward. Social Security applies at 6.2% to the $184,500 wage base for 2026, and Medicare runs 1.45% with the 0.9% surtax above $200K single.

Sample Paycheck on the State Median ($72,500)

For a single filer at Indiana's median household income of $72,500 per the Census ACS 2024 1-year brief, federal taxable income lands at $56,400 after the federal standard deduction. Federal tax sums to roughly $7,889 ($1,193 at 10%, $4,386 at 12%, $1,754 at 22%). FICA at 7.65% removes another $5,546. Indiana state tax (2.95% × $71,500 IN taxable) lands near $2,109. For a Marion County (Indianapolis) resident, additional county LIT of $1,444 (2.02% × $71,500) applies — total annual deductions of about $16,988 produce $55,512 in annual take-home pay, a 76.6% retention rate. For a Hamilton County resident (1.10% LIT), total deductions land at $16,257 with $56,243 net (77.6% retention).

The Eli Lilly Wage Premium

A senior research scientist at Eli Lilly Indianapolis, a director at Anthem (Elevance Health), or a senior product manager at Salesforce Indianapolis earning $165,000 single takes home approximately $116,500 — about $4,481 biweekly — after $26,950 federal income tax, $12,062 FICA, $4,808 Indiana state tax (2.95% × $163,000 taxable), and $3,293 Marion County LIT (2.02% × $163,000). The same role at Pfizer New York would face NY state tax (~6.85% top) plus NYC tax (3.876%) — a delta of roughly $11,000-$15,000 favoring Indianapolis. Combined with central Indiana's lower cost of living than New York, Boston, or San Francisco, the Indiana corporate wage tier produces strong real disposable income for senior tech, pharmaceutical, and finance roles.

Eli Lilly, Cummins, and the Auto Manufacturing Belt

Indiana hosts an unusually diverse industrial base for a Midwest state, anchored by global pharmaceuticals, heavy diesel manufacturing, and three Japanese auto OEMs.

Eli Lilly Indianapolis Headquarters

Eli Lilly and Company's Indianapolis headquarters anchors the largest pharmaceutical employment cluster in the Midwest, with roughly 11,000 Indiana employees across research, manufacturing, regulatory, and corporate functions. Lilly's expanded weight-loss drug portfolio (Mounjaro, Zepbound) plus diabetes therapy lineup has driven significant 2024-2026 hiring across the Indianapolis Lilly Technology Center campus and Lebanon manufacturing site. Senior research scientists earn $145K-$220K, principal medical directors $185K-$300K, senior corporate managers $165K-$245K. The cluster supports a robust subcontractor and service ecosystem (regulatory consulting, clinical research organizations, supply chain) employing another 8,000-12,000 across central Indiana.

Cummins Columbus and the Heavy Diesel Cluster

Cummins Inc. in Columbus (south-central Indiana) is the world's largest independent designer and manufacturer of diesel engines, employing roughly 10,000 in Bartholomew County. The Columbus campus runs the global Engineering and Tech Center, design centers, and fuel cell research operations. Senior diesel engineers earn $130K-$180K, principal engineers $170K-$240K, senior managers $185K-$270K. Cummins has invested heavily in electric and hydrogen powertrain development since 2022, expanding the engineering footprint with sustained hiring of mechanical, electrical, and software engineers. The Bartholomew County 1.95% LIT runs above the state average but below high-LIT urban counties like Marion.

Subaru, Honda, and Toyota

Indiana hosts three major Japanese auto OEM final-assembly plants. Subaru of Indiana Automotive (SIA) in Lafayette employs roughly 6,000 producing Outback, Forester, Ascent, and Legacy models. Honda Manufacturing of Indiana in Greensburg employs roughly 2,800 producing Civic and CR-V. Toyota Motor Manufacturing Indiana in Princeton employs roughly 7,500 producing Highlander, Sequoia, and Sienna. Combined Japanese OEM employment exceeds 16,000 across Tippecanoe, Decatur, and Gibson counties — supporting another 30,000-40,000 jobs in tier-1 and tier-2 supplier roles. Production technicians earn $55K-$75K with overtime, supervisors $80K-$110K, plant managers $130K-$210K. The OBBB overtime deduction interacts particularly favorably with shift-premium-heavy auto schedules.

Indiana Property Tax: 0.84% Effective

Indiana's effective property tax rate of 0.84% sits near the national average and below the high-LIT counties' urban concentrations. The structural cause traces to the 2008 Indiana Constitution Article 10 amendment that created the property tax cap (the "1-2-3 rule"): residential primary residences capped at 1% of assessed value, residential rental and agricultural land at 2%, and non-residential property at 3%. The cap is constitutional — local jurisdictions cannot exceed it without voter referendum. For a homeowner at the Indiana median home value of $245,000, annual property tax runs roughly $2,060 after the homestead and supplemental homestead deductions.

Indianapolis vs Carmel/Fishers vs Bloomington

Marion County (Indianapolis) effective property tax rate runs 1.05% (after the 1% constitutional cap is applied to the gross assessed value, which exceeds typical millage); Hamilton County (Carmel, Fishers, Westfield, Noblesville) 0.91%; Hendricks County 0.84%; Monroe County (Bloomington) 0.94%; Bartholomew County (Columbus) 0.78%. The combination of Indiana's constitutional 1% residential cap plus the standard $48,000 homestead deduction plus the 35% supplemental homestead deduction produces a meaningful effective-rate reduction relative to states without similar caps.

Three Wage Realities: Indianapolis Pharma, Bloomington University, Northwest Steel

The same federal-plus-Indiana 2.95%-plus-county-LIT math produces dramatically different lifestyles depending on the metro and role.

Indianapolis Eli Lilly Senior Scientist, $185,000

A senior research scientist at Eli Lilly Indianapolis, a senior software engineer at Salesforce Indianapolis, or a senior managing director at Anthem Elevance earning $185,000 single takes home approximately $130,500 — about $5,019 biweekly — after $33,633 federal income tax, $13,712 FICA, $5,376 Indiana state tax, and $3,683 Marion County LIT. Marion County median home near $245,000 with the 1% constitutional cap produces PITI of roughly $1,950/month — comfortable on this senior corporate wage tier. Many Indianapolis senior workers prefer Hamilton County (Carmel, Fishers) for school district quality and lower 1.10% LIT, accepting longer commutes for $700-$900 in annual LIT savings.

Bloomington Indiana University Researcher, $78,000

An associate research scientist at Indiana University Bloomington, a senior librarian at the IU Library System, or a research scientist at the Indiana University Health Bloomington Hospital earning $78,000 single takes home approximately $60,500 — about $2,327 biweekly — after $9,505 federal income tax, $5,967 FICA, $2,242 Indiana state tax, and $1,527 Monroe County LIT (1.96% rate). Monroe County median home near $295,000 with 0.94% property tax produces PITI of roughly $2,450/month — accessible on a university-tier wage. The Bloomington cost of living runs slightly above the state average due to IU student demand, but remains substantially below Indianapolis suburban prices.

Northwest Indiana Steel Worker, $82,000

A senior steelworker at Cleveland-Cliffs Indiana Harbor, a maintenance technician at U.S. Steel Gary Works, or a melt shop operator at ArcelorMittal Burns Harbor earning $82,000 (with overtime) takes home approximately $60,200 — about $2,315 biweekly — after $10,237 federal income tax, $6,273 FICA, $2,330 Indiana state tax, and $1,575 Lake County LIT (1.50%). Lake County median home near $215,000 with the 1% constitutional cap produces PITI of roughly $1,650/month. The Northwest Indiana steel cluster (Gary, East Chicago, Hammond) employs roughly 14,000 across three major integrated mills plus rolling mills and finishing plants. Workers commute from southern Indiana suburbs (Crown Point, Schererville, Munster) for the school district quality and lower property crime, accepting the 30-45 minute drive to the lakeshore mill complexes.

Indiana Tax Planning Moves for 2026

Three planning moves matter most for Indiana workers under the 2.95% flat state plus county LIT regime. First, model the county LIT carefully when selecting a residence. The county LIT applies based on residence on January 1 — a Marion County resident moving to Hamilton County in February still pays Marion's 2.02% for the entire year. Workers planning a move should consider timing the move to before year-end if relocating to a lower-LIT county. The annual LIT savings between Marion (2.02%) and Hamilton (1.10%) on a $100,000 worker totals roughly $920 — a meaningful housing-decision factor.

Second, claim the Indiana property tax deduction. Indiana allows a state income tax deduction of up to $3,000 for property taxes paid on a primary residence, plus a deduction of up to $3,000 for rent paid (capped at the rent-portion attributable to property tax). Both are claimed on Schedule 2 of the Form IT-40 and reduce Indiana taxable income — saving roughly $89 in state tax (2.95% × $3,000) plus the county LIT proportional reduction. The two deductions cannot be combined — workers choose either property tax (homeowners) or rent (renters), not both.

Third, take advantage of Indiana's federal-conforming retirement contribution treatment. The Indiana Mortgage Calculator handles property tax mechanics for Marion, Hamilton, Allen, Hendricks, and Bartholomew counties separately. The Indiana Affordability Calculator integrates the income tax, county LIT, and property tax sides; the Indiana financial calculators hub bundles paycheck, mortgage, and affordability tools. For federal-only mechanics including FICA and OBBB tip and overtime deductions ($25K tip / $12.5K overtime exemptions for 2026-2028), the national Paycheck Calculator provides verification.
