Indiana State-Specific Tax Details (2026)
Pass-Through Entity (PTE) Tax Election
Indiana offers an elective Pass-Through Entity Tax (PTET) for partnerships, S corporations, and LLCs taxed as a partnership or S corp. The entity-level tax rate equals Indiana's flat individual income tax rate in effect for the year (2.95% for 2026; scheduled 2.90% for 2027), and the federal deduction at the entity level is intended to work around the federal SALT cap. The election is made annually, does NOT carry over year-to-year, and must be made during the taxable year or on the entity's timely-filed original return (including extensions) by checking the PTET box on Form IT-65 or IT-20S with a Schedule PTET attached. It CANNOT be made after the original return is filed and cannot be elected by amending. Owners receive a refundable credit for their share of PTET paid. Note: contrary to a common misconception, Indiana DOES allow an Indiana-resident owner a credit for PTET paid to ANOTHER state when that state's tax is 'substantially similar' to Indiana's PTET. Confirm current-year form lines and computation codes, and any 'substantially similar' determination, with a tax professional.
Local & City Income Taxes
All 92 Indiana counties levy a resident-based Local Income Tax (LIT), charged based on where the owner LIVES (not where the business operates), on top of the 2.95% state rate (2026). 2026 county rates range from roughly 0.5% to about 3.38% at the high end (Switzerland County is among the highest, possibly tied with another county). Several counties enacted LIT rate changes effective Jan 1, 2026. Confirm any specific county's current rate against the Indiana DOR Departmental Notice #1 before relying on it.
Entity-Level & Franchise Taxes
Indiana has no franchise, gross-receipts, margin, or B&O tax (and no inventory tax). Indiana recognizes the federal S-corp election; S corps and partnerships generally pay no entity-level income tax (income flows through to owners taxed at the 2.95% individual rate for 2026 plus county LIT), except via the optional PTET election. C corporations pay the flat 4.90% Corporate Adjusted Gross Income Tax (unchanged for 2026).
Indiana Tax Credits & Incentives
Non-refundable income tax credit administered by the IEDC, generally up to 10% of qualifying capital investment (up to 15% for digital manufacturing equipment and up to 25% for logistics investments), with carryforward up to nine years, tied to job creation and capital investment. Can be claimed at the corporate, flow-through, or individual level.
Refundable credit administered by the IEDC, calculated as a negotiated percentage (not to exceed 100%) of incremental state income tax withholdings generated by net new Indiana jobs, awarded over a multi-year term (commonly up to ~10 years; recent legislation allows terms up to 20 years). Confirm the current award term with IEDC.
Indiana's PTET election is annual, non-carryover, and CANNOT be made after the original return is filed (or by amending), so calendar it deliberately each year: decide and check the Schedule PTET box on the timely-filed IT-65/IT-20S (including extensions). Factor the resident-based county LIT into the PTET math - a high-LIT county owner faces a higher combined state+local rate than a low-LIT county owner, which affects whether the entity-level cash outlay pays off. Note the state rate is scheduled to step down from 2.95% (2026) to 2.90% (2027), so multi-year cash-flow planning should use the declining schedule. Verify current-year form lines, your county's LIT rate, and any out-of-state PTET credit eligibility with an Indiana tax professional.
Top Tax Strategies for Indiana Business Owners
Indiana offers a moderate tax environment. While state taxes are manageable, combining federal and state strategies can still save you thousands each year.
Low flat rate minimizes state burden
Focus on federal optimization
S-Corp salary optimization
S-Corp Election in Indiana
For Indiana business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax. Keep in mind that Indiana's 3.05% income tax still applies to both your salary and your distributions, so the S-Corp election saves you federal self-employment tax while your state planning shifts to deductions, retirement contributions.
Example: A Indianapolis S-Corp
A Indianapolis business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — on top of whatever your Indiana state planning adds.
Retirement Plan Strategies for Indiana
Retirement plan contributions are the single most powerful tax deduction available to Indiana business owners. A Solo 401(k) allows contributions up to $69,000 in 2026 ($76,500 if you're 50+), generating tax savings of $17,000 to $24,000 at a 25-32% effective tax rate. For Indiana owners, those contributions cut both your federal bill and your 3.05% state income tax, stacking the savings.
SALT Deduction Impact in Indiana
Low SALT impact from state income tax, but county surcharges exist. The federal SALT (State and Local Tax) deduction cap increases from $10,000 to $40,000 in 2026, providing meaningful relief for business owners in states with income taxes.
