Indiana charges a flat 2.95% on federal AGI less a $1,000 exemption per filer, and under SB 243 it follows BOTH federal deductions — but for tax year 2026 only. Important: every Indiana county also levies its own income tax (0.5%-2.95%), which is not included in the figure here, so your real Indiana tax is higher.
What it means on a real paycheck
Take a single filer earning $50,000 a year, $8,000 of it in tips. Against the same person with no tips to declare, the federal deduction is worth $960.
In Indiana it is worth $236 more, because the state follows the federal deduction. Together that is $1,196.
How Indiana works out the tax
Indiana charges a flat 2.95%, after an exemption of $1,000 a person. It begins from your federal adjusted gross income and applies its own reliefs from there.
