Indiana Tax Overview for Estimated Payments

Indiana has a flat state income tax rate of 2.95% — one of the lower flat rates in the country. However, Indiana is unique in that most counties also charge a county income tax ranging from about 0.5% to 3.38% depending on where you live and work. This means your actual effective Indiana income tax rate is higher than 2.95% for most residents. Marion County (Indianapolis) charges an additional 2.02% county tax, for example. Indiana does not have a standard deduction in the traditional sense but offers personal exemptions. The combination of a low state rate plus county taxes means Indiana workers' take-home varies significantly by county. Compared to neighboring Ohio (0-2.75% state + city taxes) and Illinois (4.95% flat, no county tax), Indiana's total burden is similar but structured differently.
