OVERVIEW
Washington State has no state income tax (0%), while Indiana charges a flat 2.95% on all income. At $100,000, Washington State saves approximately $2,700/year. Indiana's flat rate is lower than most Midwestern states, but Indiana counties also levy income taxes ranging from 0.5% to 2.9%, which can add significantly to the burden. Marion County (Indianapolis) charges 2.02% county income tax, bringing the combined rate to approximately 4.97%. Washington State has higher housing costs and sales taxes than Indiana but wins decisively on income taxes. Indiana is one of the more tax-friendly Midwestern states — but still no match for Washington State's zero income tax.

FAQ

Frequently Asked Questions

How does Indiana's income tax work with county taxes?

Indiana has two layers of income tax: (1) State flat rate of 2.95% on all income. (2) County income tax that ALL 92 Indiana counties levy, ranging from 0.5% (Benton County) to 2.9% (Pulaski County). Marion County (Indianapolis) charges 2.02%, making the combined rate 4.97% for Indianapolis residents. On $100,000: Indiana state + Marion County = $4,970. Washington State: $0. Even the lowest-county residents pay 3.45% combined. Washington State beats Indiana at every county.

Is Indiana one of the lower-tax Midwestern states?

Yes, Indiana's state flat rate of 2.95% is lower than Illinois (4.95%), Michigan (4.25%), Ohio (2.75% but plus city taxes), Wisconsin (3.5-7.65%), and Minnesota (5.35-9.85%). However, Indiana's mandatory county income taxes (0.5-2.9%) raise the combined burden for most residents. Indianapolis residents pay ~4.97% combined — higher than Ohio's state rate. Washington State beats all Midwestern states with 0% income tax.

How does housing affordability affect the WA vs IN comparison?

Indiana offers extraordinary housing affordability: Indianapolis median ~$250k, Fort Wayne ~$185k, South Bend ~$170k vs Seattle ~$780k. However, Seattle tech salaries ($120k-$200k for software engineers) are 40-70% higher than Indiana equivalents ($70k-$120k). A $150k Seattle salary after WA's 0% income tax vs an equivalent $100k Indiana salary after ~4.97% income tax: Seattle worker keeps $53,000/year more after accounting for the $4,970 Indiana tax + $50k salary difference. Indiana housing affordability doesn't fully offset the earnings gap.

Are there any taxes where Indiana beats Washington State?

Yes, but only on one dimension now: Indiana's 7% flat sales tax rate (no local additions) is lower than Seattle's 10.1-10.5%, saving $310-$700/year on spending. Property tax is no longer a real Indiana advantage — Indiana's effective rate (~0.76%) is now almost identical to Washington State's (~0.75%), a negligible ~$40/year difference on a $400k home. Indiana's income tax (2.95% + county 0.5-2.9%) outweighs the modest sales-tax savings for most earners. Net verdict: Washington State wins for income above $60k/year; Indiana may win for low-income earners who benefit from its lower sales tax.
