Self-Employment Tax in Nebraska (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

Self-employment tax is a federal tax of 15.3% — 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare — charged on 92.35% of your net self-employment earnings and reported on Schedule SE. Nebraska imposes no self-employment tax of its own, but the same profit is taxed again under the Nebraska individual income tax.

What Self-Employment Tax Is and Who Pays It

Self-employment tax is the Social Security and Medicare tax paid by people who work for themselves. An employee sees these taxes as FICA withholding, with the employer paying a matching share behind the scenes. When you are self-employed there is no employer, so you pay both halves — which is why the combined rate is 15.3% rather than the 7.65% that shows up on a pay stub. It is a federal tax collected by the IRS. Nebraska is not involved in assessing or collecting it.

You owe self-employment tax if your net earnings from self-employment are $400 or more for the year. That covers Nebraska freelancers and consultants, independent contractors who receive Forms 1099-NEC, gig and platform workers, farmers and ranchers with Schedule F income, partners in a partnership, and members of a single-member LLC treated as a disregarded entity. Paying it is not purely a cost: the tax credits your earnings record with the Social Security Administration and builds the work quarters that qualify you for retirement, disability, and Medicare coverage. For the national explainer, see self-employment tax.

The 15.3% Rate: Social Security and Medicare

The rate splits into two components with very different ceilings. The Social Security portion is 12.4% and applies only up to an annual ceiling called the contribution and benefit base, more commonly the Social Security wage base, which the Social Security Administration adjusts each year for average wage growth. Once your combined W-2 wages and net self-employment earnings pass that ceiling, the 12.4% stops for the year. The Medicare portion is 2.9% and has no ceiling — it applies to every dollar of net self-employment earnings. Because the wage base changes annually, look up the current figure on the SSA's contribution and benefit base page before you run numbers.

A third layer catches higher earners. The Additional Medicare Tax of 0.9% applies to combined wages and self-employment income above $200,000 for single filers and $250,000 for married couples filing jointly. It is computed on Form 8959 rather than on Schedule SE, and unlike the base Medicare tax it has no employer-side match. Keep in mind that all of this is separate from federal income tax and separate again from Nebraska income tax; it is entirely possible to owe self-employment tax in a year when your income tax bill is small.

How to Calculate SE Tax on 92.35% of Net Earnings

You never pay self-employment tax on gross revenue. First, compute net profit on Schedule C: revenue minus ordinary and necessary business expenses. Then Schedule SE multiplies that profit by 92.35% to reach "net earnings from self-employment." The 7.65% haircut approximates the employer-side FICA that an employee would never be taxed on, and it is what keeps a self-employed person roughly even with an employee earning the same amount. The 15.3% rate is applied to that adjusted figure, subject to the Social Security ceiling.

Worked through: a Nebraska consultant with $60,000 of net profit multiplies by 0.9235 to get $55,410 of net earnings from self-employment. That is below the wage base, so the full 15.3% applies and produces roughly $8,478 of self-employment tax, of which about $4,239 is deductible on the federal return. Your own figures will differ with the current wage base, any W-2 wages you also earned, and your expense deductions, so run them with the Schedule SE instructions or the self-employment tax calculator rather than relying on the illustration.

Reporting on Schedule SE and Form 1040

Self-employment tax is reported on Schedule SE (Form 1040), attached to your federal return. The profit that drives it comes from Schedule C for most businesses, Schedule F for farming and ranching, or a Schedule K-1 for a partner's distributive share. Once Schedule SE computes the tax, the total carries to Schedule 2 as an "other tax," and the deductible one-half becomes an adjustment to income on Schedule 1. Schedule SE is never filed with Nebraska — it stays with the federal return — but the profit line it starts from is the same profit Nebraska will tax.

If you have elected to have your LLC taxed as an S corporation, the arithmetic changes. Wages the S corporation pays you are subject to FICA and are reported on a W-2; remaining profit distributed to you is not subject to self-employment tax. That is the mechanism behind the "S-corp saves SE tax" advice, and it is real — but it only works if the wage you pay yourself is genuinely reasonable for the work you do, and it brings payroll filings and added accounting cost that can outweigh the savings at modest profit levels.

How Nebraska Taxes the Same Profit

Nebraska does not impose a self-employment tax. It does, however, tax the same business profit through the Nebraska individual income tax, administered by the Nebraska Department of Revenue. Nebraska begins from your federal adjusted gross income, so the net profit from Schedule C arrives in the Nebraska computation automatically, and state adjustments are applied from there. Residents file Form 1040N; part-year residents and nonresidents use the same form with a Nebraska allocation schedule.

Nebraska applies graduated individual income tax rates, and the legislature has revised those rates and brackets repeatedly in recent sessions as part of a multi-year rate reduction. For that reason, confirm the rate and bracket thresholds for your filing year directly with the Department of Revenue rather than relying on a figure quoted anywhere else, including here. What does not change is the structure: one dollar of business profit is taxed federally twice — income tax plus self-employment tax — and once more by Nebraska, and there is no Nebraska credit that offsets federal self-employment tax.

Separately, if you sell taxable goods or certain services in Nebraska, you register for sales and use tax on the Nebraska Tax Application, Form 20, and collect and remit that tax on its own schedule. Sales tax registration is unrelated to self-employment tax, but it is the second most common Nebraska obligation new self-employed people miss.

Quarterly Estimated Taxes, Federal and Nebraska

Because nobody withholds tax from a client payment, the tax system expects you to prepay as you earn. Federally, if you expect to owe $1,000 or more after withholding and credits, you make quarterly estimated payments using Form 1040-ES. The four installments are ordinarily due in mid-April, mid-June, mid-September, and mid-January of the following year, and the IRS charges an underpayment penalty when you fall short, even if you pay the full balance by the filing deadline. Nebraska runs a parallel system on Form 1040N-ES.

The practical habit that keeps this manageable is to move a fixed percentage of every client payment into a separate account the day it lands — enough to cover federal income tax, the 15.3% self-employment tax, and Nebraska income tax. Confirm the current thresholds, safe-harbor percentages, and due dates on the IRS estimated taxes page and with the Nebraska Department of Revenue before you rely on them; both change.

Deductions and What Actually Lowers the Bill

The most direct lever is ordinary business expenses. Every legitimate deduction on Schedule C reduces net profit, and net profit is the input to both self-employment tax and income tax — so accurate expense tracking cuts two taxes at once. Home-office expense, mileage, software, supplies, professional fees, and the business share of a phone plan are the common ones. Keep contemporaneous records; reconstructed mileage logs are a standard audit weak point.

The second lever is the deduction for one-half of self-employment tax, taken as an adjustment to income on the federal return. It lowers federal AGI, and because Nebraska starts from federal AGI, it flows through to the state return as well. Be aware of what does not help: contributions to a self-employed retirement plan, the self-employed health insurance deduction, and the qualified business income deduction all reduce income tax but do not reduce self-employment tax, because SE tax is computed on net earnings before any of them. Once profit is consistently high, the remaining structural lever is entity choice — see S-corp vs LLC and discuss the payroll trade-off with a tax professional before electing.

Frequently Asked Questions

How much is self-employment tax in Nebraska?

The self-employment tax rate is 15.3%, made up of 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare with no ceiling, applied to 92.35% of your net earnings. Nebraska adds no separate self-employment tax, but the same profit flows into Nebraska taxable income on Form 1040N.

Does Nebraska have its own self-employment tax?

No. Self-employment tax is a federal Social Security and Medicare tax collected by the IRS on Schedule SE. Nebraska has no state equivalent. Instead, your net profit from Schedule C flows through federal adjusted gross income into the Nebraska individual income tax return, where the state's graduated rates apply.

What form reports self-employment tax?

You compute self-employment tax on Schedule SE and attach it to Form 1040. Business profit is figured first on Schedule C, or Schedule F for farming, or comes from a Schedule K-1 for partnership income. The deductible one-half of the tax is claimed as an adjustment to income on Schedule 1.

Do I have to make quarterly estimated payments in Nebraska?

Generally yes. Federally, if you expect to owe $1,000 or more you pay quarterly on Form 1040-ES. Nebraska has a parallel system using Form 1040N-ES for state estimated payments. Because no employer withholds from self-employment income, missing these payments can trigger an underpayment penalty.

Is self-employment tax deductible?

Yes, in part. You may deduct one-half of your self-employment tax as an adjustment to gross income on the federal return. That lowers federal adjusted gross income, which is the starting point for the Nebraska return, so it can modestly reduce Nebraska tax as well. It does not reduce the SE tax itself.

When does the extra 0.9% Medicare tax apply?

The Additional Medicare Tax of 0.9% applies to self-employment income and wages above $200,000 for single filers or $250,000 for married couples filing jointly. It sits on top of the 2.9% Medicare portion, is computed on Form 8959 rather than Schedule SE, and has no employer-matched half.
