Common Indiana tax questions

Did Indiana's rate fall for 2026?Yes. Indiana DOR lists a 2.95% state individual rate for 2026.
Is county tax included automatically?No. Use the optional local-rate field with the current county rate that applies to you.
Are enhanced child exemptions included?No. The calculator includes only the basic $1,000 dependent amount, not every child or adoption enhancement.
What about reciprocity?Indiana has wage reciprocity with several neighboring states, but nonresident filing and withholding refunds are not modeled.
Which county determines the rate?Residence and employment rules can matter, so confirm the applicable county under Indiana guidance.
Is this Form IT-40?No. It is a planning estimate, not a full state and county return calculation.
