Nebraska does not have its own standard deduction. The starting point is federal AGI, and Nebraska applies its own adjustments to arrive at Nebraska taxable income.

| Filing status | Credit amount |
|---|---|
| Single | $157 |
| Married filing jointly | $314 |
| Each dependent | $157 |
Nebraska does not permit local income taxes.
Nebraska taxable income starts with federal adjusted gross income (AGI) from federal Form 1040, Line 11.
Key addition modifications (Schedule I)
| Addition | Description |
|---|---|
| State/local bond interest | Interest from bonds of states other than NE |
| Bonus depreciation add-back | NE partially decouples from IRC §168(k) — verify current conformity status |
Key subtraction modifications (Schedule I)
| Subtraction | Description |
|---|---|
| US government bond interest | Interest from US Treasury obligations |
| State income tax refund | If included in federal AGI |
| Social Security (partial) | Nebraska is phasing out Social Security taxation — for TY 2025, Social Security benefits are fully exempt |
Schedule C net profit flows into federal AGI, which is the starting point for Nebraska. Nebraska conforms to the federal self-employment tax deduction (the deductible half of SE tax is already reflected in federal AGI).

Form 1040N-ES is used for estimated tax payments.
Nebraska's conformity with federal bonus depreciation under IRC §168(k) should be verified for the current tax year. Nebraska has historically required partial add-backs for bonus depreciation in certain years. Check the 2025 Form 1040N instructions.
Nebraska is one of six states with an inheritance tax (separate from estate tax). This is administered at the county level and is not covered by this income tax skill. Self-employed taxpayers should be aware of this for estate planning purposes.
