Nebraska self-employment tax, explained

Nebraska is mid-way through a multi-year legislated rate-cut schedule that brought its top rate down to 4.55% for 2026 (on the way to 3.99% in 2027) — basing quarterly vouchers on a prior year's rate will overpay.

Self-employment (SE) tax is the same everywhere — 15.3% of 92.35% of your net profit, split between Social Security (12.4%, up to the annual wage base) and Medicare (2.9%, uncapped). What changes by state is the income tax layer on top: Nebraska has a progressive income tax with a top rate of 4.55%, applied to your taxable income after federal deductions. For filing status, Nebraska's tax uses separately-scaled brackets for joint filers that aren't simply double the single-filer thresholds.

Frequently asked questions

What is the Nebraska state income tax rate for 1099 income?

Nebraska has a progressive income tax with a top rate of 4.55%. Its tax uses separately-scaled brackets for joint filers that aren't simply double the single-filer thresholds. See the "Nebraska self-employment tax, explained" section above for how it applies to your specific numbers.

How is self-employment tax calculated?

Self-employment tax is 15.3% of your net self-employment earnings (92.35% of net profit): 12.4% Social Security up to the annual wage base, plus 2.9% Medicare on all net earnings. If your combined income exceeds the Additional Medicare Tax threshold for your filing status, an extra 0.9% applies above that threshold.

What's the difference between self-employment tax and income tax?

Self-employment tax funds Social Security and Medicare — it's the self-employed equivalent of the payroll taxes an employer would otherwise split with you. Federal (and state) income tax is separate, calculated on your taxable income after deductions like the standard deduction and the QBI deduction.
