Does Nebraska Tax Social Security Benefits? 2026 Update

As of tax year 2025, Nebraska fully exempts all Social Security benefits from state income tax. There are no income thresholds and no phase-outs. It does not matter how much you earn or how much of your benefit is taxable at the federal level. Nebraska no longer taxes any of it. Federal Social Security taxes may still apply based on your total income, but Nebraska steps completely out of that calculation. For Nebraska retirees, this is a meaningful and permanent improvement to take-home retirement income.

What Changed and When

Nebraska completed a multi-year phase-out of its Social Security state income tax with the full exemption taking effect for tax year 2025. The phase-out progressed gradually: 40% exempt in tax year 2022, 60% exempt in 2023, 80% exempt in 2024, and 100% exempt starting in 2025. The full exemption is permanent under current law.

That means Nebraska retirees who filed state returns in 2022, 2023, or 2024 were still paying some Nebraska state tax on a portion of their Social Security income. Starting with the 2025 tax year, that state tax is gone entirely, regardless of income level.

For context on how meaningful this is: a Nebraska couple with $50,000 in annual Social Security income who previously paid Nebraska state income tax on 80% of that benefit in 2024 could have owed $2,000 to $4,000 or more in Nebraska state tax on those benefits. Starting in 2025, that bill is zero. Always verify current guidance at revenue.nebraska.gov.

What Nebraska Still Taxes and What It Does Not

The Social Security exemption is part of a broader improvement in Nebraska’s treatment of retirement income, but it is important to understand what is and is not exempt.

Fully exempt from Nebraska state income tax as of 2025:

• All Social Security benefits, regardless of income level
• Military retirement pay
• Federal civil service annuities
• Railroad Retirement Board benefits

Still taxable in Nebraska:

• Private pension income
• Traditional IRA and 401(k) distributions
• Annuity income funded with pre-tax dollars
• Wages and self-employment income

This distinction matters significantly for retirement income planning in Nebraska. A retiree whose income comes primarily from Social Security and military or federal retirement benefits is in a very different Nebraska tax position than one whose income comes primarily from traditional IRA withdrawals. Coordinating your income sources strategically can meaningfully reduce your Nebraska state tax burden in retirement.

Federal Social Security Taxes Still Apply

Nebraska’s full exemption only covers state income tax. The federal government uses its own formula to determine how much of your Social Security benefit is taxable on your federal return, and that calculation is unchanged by Nebraska’s exemption.

Under federal rules, up to 85% of your Social Security benefits can be taxable if your combined income, which is your adjusted gross income plus non-taxable interest plus half of your Social Security benefits, exceeds $34,000 for single filers or $44,000 for married filers. Benefits begin to become partially taxable at $25,000 for singles and $32,000 for married couples.

Nebraska now steps completely out of that calculation. Whatever the IRS determines is taxable at the federal level, Nebraska adds no state tax on top of it. For Nebraska retirees, this means the remaining focus for Social Security tax optimization is at the federal level through strategies like Roth conversions, coordinated withdrawal sequencing, and Social Security claiming timing. See SSA.gov and IRS Publication 590-B for federal rules.

Why This Matters for Nebraska Retirement Income Planning

The full Social Security exemption increases take-home income for Nebraska retirees compared to prior years, but it also changes the income planning calculus in important ways.

Because Social Security is now fully exempt at the state level, Nebraska retirees can focus their income optimization entirely on federal tax management. That means strategies like Roth conversions to reduce future IRA withdrawal income, coordinating withdrawal sequencing to stay below federal IRMAA thresholds, and timing Social Security claims to maximize the benefit amount while minimizing federal taxation become the primary levers available.

It also means that IRA and 401(k) withdrawals, which remain fully taxable in Nebraska, deserve careful attention in retirement income planning. A large traditional IRA balance that generates significant RMDs will be taxed at both the federal and Nebraska state level. Reducing that future tax burden through strategic Roth conversions before RMDs begin is one of the most valuable planning moves available to Nebraska pre-retirees today. See How Do Roth Conversions Lower Lifetime Taxes for the full strategy.

How the Nebraska Exemption Affects IRMAA Planning

Medicare IRMAA surcharges are calculated using your federal Modified Adjusted Gross Income from two years prior, not your Nebraska state taxable income. So the Nebraska Social Security exemption does not directly reduce your IRMAA exposure. However, it does affect your overall income picture in ways that matter for planning.

Because Nebraska no longer adds state tax on top of Social Security income, Nebraska retirees have more flexibility to manage their federal MAGI without worrying about simultaneously triggering state tax on their benefits. Strategies designed to keep federal MAGI below IRMAA thresholds, like Roth conversions, QCDs, and coordinated withdrawal sequencing, can be executed without the additional concern of Nebraska state tax on Social Security income complicating the picture. See What Is IRMAA and Why Does It Matter for the full 2026 bracket breakdown.

Summary

Nebraska fully exempts all Social Security benefits from state income tax as of tax year 2025 with no income limits and no phase-outs. The exemption is permanent under current law. Military retirement pay, federal civil service annuities, and Railroad Retirement Board benefits are also fully exempt. Traditional IRA and 401(k) withdrawals remain taxable in Nebraska. Federal Social Security taxes continue to apply based on your combined income. For Nebraska retirees, the focus of income tax optimization shifts entirely to the federal level, where strategies like Roth conversions, withdrawal sequencing, and Social Security timing remain the most powerful tools available.

Frequently Asked Questions

Does the Nebraska Social Security exemption reduce my Medicare IRMAA surcharges?

No. IRMAA surcharges are calculated using your federal Modified Adjusted Gross Income, not your Nebraska state taxable income. The Nebraska exemption removes state tax on Social Security but does not change how the federal government calculates your MAGI for IRMAA purposes. Managing federal MAGI through Roth conversions, coordinated withdrawals, and QCDs remains the primary tool for IRMAA management in Nebraska.

Should Nebraska retirees still do Roth conversions if Social Security is exempt?

Yes, absolutely. The Nebraska Social Security exemption removes state tax on Social Security income, but traditional IRA and 401(k) withdrawals remain fully taxable in Nebraska. Large RMDs from pre-tax accounts will be taxed at both the federal and Nebraska state level. Strategic Roth conversions before RMDs begin reduce future taxable distributions, lower federal MAGI for IRMAA purposes, and reduce Nebraska state income tax on retirement income that does not qualify for the Social Security exemption.

Are RMDs from traditional IRAs taxable in Nebraska?

Yes. Traditional IRA and 401(k) distributions, including Required Minimum Distributions, are fully taxable in Nebraska as ordinary income. Only Social Security, military retirement pay, federal civil service annuities, and Railroad Retirement Board benefits are exempt. This makes proactive RMD planning and Roth conversion strategies particularly valuable for Nebraska retirees with large pre-tax retirement account balances.

How does Social Security claiming timing affect Nebraska taxes?

Since Nebraska fully exempts Social Security at the state level, the timing of your Social Security claim no longer affects your Nebraska state tax bill directly. However, federal Social Security taxation still applies, and claiming timing affects how much of your benefit is taxable at the federal level. Delaying to age 70 increases your benefit by up to 32% permanently and can be coordinated with Roth conversions during the deferral period to minimize federal tax on future Social Security income.

Is Protected Lifetime Income from annuities taxable in Nebraska?

It depends on the funding source. PLI income from a pre-tax funded annuity, such as a traditional IRA annuity, is taxable as ordinary income in Nebraska. PLI income from an after-tax funded annuity uses an exclusion ratio where only the earnings portion is taxable. Roth-funded PLI income is completely tax-free at both the federal and Nebraska state level. Choosing the right funding source for your PLI strategy is an important planning decision for Nebraska retirees.

How do fees and taxes still affect Nebraska retirees even with the Social Security exemption?

The Social Security exemption eliminates one source of state tax drag, but Nebraska still taxes traditional IRA withdrawals, 401(k) distributions, private pensions, and annuity income funded with pre-tax dollars. Investment fee drag continues to silently erode portfolio value regardless of state tax rules. The 6-Link Tax Cascade at the federal level, including RMDs triggering higher Social Security taxation and IRMAA surcharges, remains fully in play. Fee-aware and tax-smart planning continues to be essential for Nebraska retirees.

What is the smartest withdrawal strategy for Nebraska retirees?

For Nebraska retirees, a smart withdrawal strategy coordinates Roth account withdrawals, traditional IRA distributions, and Protected Lifetime Income to minimize both federal MAGI for IRMAA purposes and Nebraska state income tax on taxable distributions. Since Social Security is fully exempt at the state level, the primary Nebraska tax concern shifts to managing traditional IRA and 401(k) withdrawal income, making Roth conversion planning before RMDs begin one of the highest-value strategies available.

How does the Nebraska exemption affect inflation and sequence risk planning?

The Social Security exemption increases net take-home income for Nebraska retirees, which strengthens the income floor available to cover essential expenses. A higher net Social Security benefit combined with Protected Lifetime Income creates a more robust guaranteed income floor, reducing the amount of portfolio withdrawals needed for essentials and therefore reducing exposure to sequence of returns risk. Every dollar of state tax saved on Social Security is a dollar that strengthens your retirement income foundation.
