## Assumptions

- An estimate for a full-year resident, 2026 rates, not tax advice.
- Starts from federal AGI; Indiana additions and subtractions are not modelled.
- Not modelled for Indiana: Dependent exemption is $1,000 plus the $1,500 additional amount for a qualifying child. County tax is in the local rows. No itemized deductions: IT-40 subtracts its own Schedule 2 deductions and exemptions, not federal itemized deductions (2025 IT-40 booklet).
- Not modelled: part-year and nonresident returns, other state credits, and state AMT.

### What does this Indiana calculator leave out?

Dependent exemption is $1,000 plus the $1,500 additional amount for a qualifying child. County tax is in the local rows. No itemized deductions: IT-40 subtracts its own Schedule 2 deductions and exemptions, not federal itemized deductions (2025 IT-40 booklet). It also leaves out state additions and subtractions to federal AGI (such as retirement or Social Security exclusions), part-year and nonresident returns, and credits such as child care, earned income, and tax paid to another state.

### Which tax year do the Indiana rates cover?

Tax year 2026, the return you file in 2027. They come from Indiana DOR.

### Which states have no income tax on wages?

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. They have no page of their own, because there is no wage income tax to work out; the state income tax calculator answers 0 for them. Federal income tax and Social Security and Medicare still apply.

### Is this the same as my paycheck withholding?

No. This is the tax for the whole year on your return. Your employer withholds by the state's own withholding formula, so your refund or balance due is the difference between the two.
