Does Indiana Tax Overtime in 2026?

Likely no - Indiana is expected to recognize the federal overtime deduction, but official guidance is pending. Indiana's IRC conformity framework appears to capture the OBBBA (per RSM analysis), which would mean the federal overtime deduction (IRC §225) reduces Indiana adjusted gross income. However, the Indiana Department of Revenue has not yet published deduction-specific guidance confirming this treatment. If confirmed, workers would save 2.95% (state) plus their county income tax rate (0.5%-3.38%) on up to $12,500 ($25,000 MFJ) in qualifying overtime premium pay.

How Indiana's Overtime Tax Treatment Works

Indiana's conformity to the OBBBA overtime deduction depends on how its general IRC conformity framework incorporates the new provision.

General IRC conformity: Indiana's income tax law generally conforms to the Internal Revenue Code. An analysis by RSM (a national accounting firm) indicates that Indiana's IRC-date-level conformity captures the OBBBA provisions, including the overtime deduction (IRC §225). This means the deduction should be part of Indiana's tax law.

Pending DOR guidance: The Indiana Department of Revenue has not published a bulletin or departmental notice specifically confirming the OBBBA overtime deduction applies for Indiana purposes. The interaction between the deduction and Indiana's 92-county income tax system is a key open question - county taxes are computed on a base derived from Indiana AGI, and the flow-through treatment needs clarification.

Practical impact: If conformity is confirmed, a worker with $12,500 in qualifying overtime (the federal cap for single filers) would save $368.75 in state tax at 2.95%, plus savings on county tax that varies by county. In Marion County (Indianapolis), that county savings would be approximately $252.50. The combined savings could range from $431 to $791 depending on the county rate.

Worked Examples Comparing Federal and Indiana Treatment

Example 1: Factory worker in Marion County (single filer, $50,000 income, $8,000 overtime premium)

Federal return:
Qualifying overtime premium: $8,000
Overtime deduction claimed: $8,000 (capped at $12,500)
Estimated federal tax savings: $960.00

Indiana return:
Indiana is expected to recognize the federal overtime deduction based on IRC-date-level conformity, but official DOR guidance has not been issued. If confirmed, the $8,000 deduction would save approximately $236 in state tax (2.95%) plus $161.60 in Marion County tax (2.02%), for a combined state+county savings of roughly $397.60. Until DOR guidance is published, this savings is probable but not guaranteed.

Example 2: Nurse in Marion County (single filer, $75,000 income, $12,500 overtime premium - federal cap reached)

Federal return:
Qualifying overtime premium: $12,500
Overtime deduction claimed: $12,500 (capped at $12,500)
Estimated federal tax savings: $2,750.00

Indiana return:
If Indiana confirms conformity to the OBBBA overtime deduction, the $12,500 deduction would save approximately $368.75 in state tax (2.95%) plus $252.50 in Marion County tax (2.02%), for a combined savings of roughly $621.25. Official DOR guidance is still pending as of August 2026.

Indiana's 92 Counties Add Significant Tax Variation

Indiana's county income tax system creates wide variation in the total tax impact on overtime. Key county rates include:

Marion County (Indianapolis): approximately 2.02% - combined state+county rate of 4.97%
Lake County: approximately 1.50% - combined rate of 4.45%
Allen County (Fort Wayne): approximately 1.48% - combined rate of 4.43%
Hamilton County: approximately 1.00% - combined rate of 3.95%
St. Joseph County (South Bend): approximately 1.75% - combined rate of 4.70%

If the OBBBA overtime deduction is confirmed, workers in high-county-rate areas would see the largest combined savings because the deduction would reduce both the state and county tax base.

Indiana's Manufacturing and Logistics Workforce

Indiana has a large manufacturing and logistics sector where overtime is common. The state's flat 2.95% rate is among the lower state income tax rates nationally, but county taxes can add substantially. For a factory worker in a county with a 2% rate, the combined 4.95% burden on overtime is significant - making the pending OBBBA conformity question particularly relevant for Indiana's industrial workforce.

Conformity Recheck Date - September 1, 2026

Our records indicate that Indiana's OBBBA conformity status should be rechecked on or after September 1, 2026. The DOR may issue guidance through an Information Bulletin, a departmental notice, or updated filing instructions for the 2026 IT-40 return. This page will be updated when official guidance is published.

Frequently Asked Questions

Does Indiana conform to the federal OBBBA overtime deduction?

Likely yes, but not officially confirmed. Indiana's IRC conformity framework appears to capture the OBBBA based on IRC-date-level conformity (per RSM analysis). However, the Indiana Department of Revenue has not published deduction-specific guidance confirming that the overtime deduction (IRC §225) applies for Indiana income tax purposes. Workers should check the Indiana DOR website for updates.

What Indiana tax rates apply to overtime pay?

Indiana imposes a flat 2.95% state income tax on all taxable income for tax year 2026. In addition, all 92 Indiana counties levy their own income taxes, ranging from 0.5% to 3.38%. If the overtime deduction is not recognized, the combined state-plus-county rate on overtime ranges from approximately 3.45% to 6.33% depending on your county of residence.

Would the overtime deduction reduce my Indiana county taxes too?

If the OBBBA overtime deduction flows through to Indiana adjusted gross income (as expected under general IRC conformity), it would also reduce the base for county income tax - providing savings at both the state and county level. However, the Indiana DOR has not confirmed how the deduction interacts with the county tax computation. This is one of the key questions pending in official guidance.

When will Indiana issue guidance on OBBBA overtime conformity?

The Indiana DOR has not announced a timeline. Our records suggest a recheck date of September 1, 2026. Workers and tax preparers should monitor the Indiana DOR website (in.gov/dor) for Information Bulletins or departmental notices addressing the OBBBA overtime deduction.

How does Indiana's flat tax affect overtime workers compared to graduated-rate states?

Indiana's flat 2.95% rate means the state tax savings from the overtime deduction is the same regardless of total income: 2.95% of the deduction amount. In graduated-rate states, higher earners save more per dollar of deduction. However, Indiana's county taxes (which vary from 0.5% to 3.38%) add a second layer that can make the total tax burden on overtime comparable to some graduated-rate states.

Should I file my Indiana return assuming the overtime deduction applies?

This is a decision to make with your tax preparer. If Indiana's general IRC conformity captures the OBBBA (as RSM's analysis suggests), claiming the deduction would be consistent with the law. However, without explicit DOR guidance, there is some risk. Consult a tax professional familiar with Indiana conformity rules for personalized advice.
