Wisconsin Income Tax Guide 2026 | Rates, Brackets & Calculator

Wisconsin uses a four-bracket progressive income tax with rates from 3.54% to 7.65%. The state offers a significant 60% exclusion on long-term capital gains — meaning Wisconsin's effective capital gains rate tops at approximately 3.06%, far below neighboring Minnesota (9.85% on all gains). Social Security and military retirement income are fully exempt.

Wisconsin's standard deduction phases out at relatively low income levels ($15,950 for single filers), meaning most middle-income earners lose most of their deduction. Property taxes average approximately 1.73% — one of the higher rates in the Midwest.

Wisconsin Income Tax Brackets 2026: 3.54% to 7.65%

Wisconsin has four progressive income tax brackets for 2026. Each rate applies only to income within that bracket range — you do not pay the top rate on your entire income.

Single Filer Brackets

Married Filing Jointly Brackets

Wisconsin's bracket thresholds are adjusted annually for inflation. The third bracket (5.30%) is the broadest, covering the majority of middle- and upper-middle-income earners. Most Wisconsin filers never reach the 7.65% top rate.

How Wisconsin Compares to Neighboring States

Wisconsin's income tax burden sits between Minnesota (higher) and Iowa/Michigan (lower) for most income levels. Unlike Minnesota, Wisconsin has no state estate tax. Unlike Illinois, Wisconsin's rate is progressive rather than flat — meaning lower earners pay less. No Wisconsin city levies a local income tax, unlike some cities in Michigan and Ohio.

Wisconsin Standard Deduction and Personal Exemption: The Phase-Out Trap

Wisconsin's standard deduction is one of the most important — and most misunderstood — elements of the state tax system. Unlike the federal standard deduction, which is a fixed amount available to all filers, Wisconsin's standard deduction phases out rapidly as income rises, dramatically affecting the tax burden on middle-income earners.

2026 Standard Deduction Amounts and Phase-Out Thresholds

The phase-out is aggressive: for every dollar earned above the phase-out threshold, the standard deduction shrinks by a proportional amount. A single filer earning $100,000 receives only a small fraction — or potentially none — of the $12,760 standard deduction. This means Wisconsin's effective tax burden on earners above $30,000–$40,000 is higher than the headline brackets suggest at first glance.

Personal Exemption

Wisconsin allows a personal exemption of $700 per exemption claimed. A single filer claims one exemption ($700 deduction); a married couple claims two ($1,400 total). Additional exemptions may be available for dependents. The personal exemption is not subject to the same phase-out as the standard deduction and applies for most income levels.

Practical Impact of the Phase-Out

Consider two single filers: one earning $15,000 and one earning $100,000. The $15,000 filer receives the full $12,760 standard deduction plus $700 personal exemption — reducing Wisconsin taxable income to near $1,540 and resulting in minimal tax. The $100,000 filer loses most or all of the standard deduction due to phase-out — paying tax on substantially all income above the $700 personal exemption. This phase-out structure means Wisconsin's effective rate on upper-middle incomes is steeper than the 5.30% bracket rate alone implies.

Wisconsin residents who pay significant mortgage interest and other itemized deductions may find that itemizing produces a larger deduction than the reduced standard deduction — particularly if Wisconsin taxable income is substantial. Wisconsin conforms to federal itemized deduction rules, with some modifications.

Wisconsin's 60% Capital Gains Exclusion: A Key Differentiator for Investors

Wisconsin offers a significant tax break for long-term capital gains that distinguishes it from many Midwestern neighbors and makes the state notably more attractive for investors, business owners selling assets, and retirees living on investment income.

How the 60% Exclusion Works

Wisconsin excludes 60% of net long-term capital gains from Wisconsin taxable income. Only 40% of long-term capital gains are included in Wisconsin taxable income and subject to Wisconsin income tax rates. This is not a separate preferential tax rate — rather, it is a deduction that reduces the amount of gain that enters the Wisconsin tax base.

Effective Wisconsin Tax Rates on Long-Term Capital Gains

For a high-income Wisconsin investor who would otherwise be in the 7.65% bracket, long-term capital gains are effectively taxed at only about 3.06% at the state level. This is substantially lower than Minnesota, where capital gains are taxed as ordinary income at up to 9.85% with no exclusion — a difference of nearly 7 percentage points on large gains.

What Qualifies as a Long-Term Capital Gain?

Long-term capital gains are gains on assets held for more than 12 months. This includes:

• Stocks, ETFs, and mutual fund shares held over one year
• Real estate (other than your primary residence, which may qualify for separate federal/state exclusions)
• Business interests held for more than 12 months
• Collectibles and other capital assets held long-term

Short-term capital gains — on assets held 12 months or less — do not qualify for the 60% exclusion and are taxed as ordinary income at Wisconsin's standard bracket rates.

Wisconsin vs. Minnesota: Capital Gains Tax Comparison

The capital gains treatment is one of the most significant reasons a high-income investor or business owner might choose Wisconsin over Minnesota:

• Wisconsin: LT gains effectively taxed at ~3.06% at the top bracket
• Minnesota: LT gains taxed as ordinary income at up to 9.85% — no exclusion
• Iowa: LT gains taxed as ordinary income at flat 3.8% — Iowa's flat rate produces a similar or slightly higher result for most investors
• Illinois: LT gains taxed as ordinary income at flat 4.95%

For a Wisconsin resident selling a $1 million long-term capital gain, the state tax at the top bracket is approximately $30,600. The same gain in Minnesota would generate approximately $98,500 in state income tax — a difference of over $67,000 for a single transaction.

Social Security, Military Retirement, and Other Retirement Income in Wisconsin

Social Security: Fully Exempt

Wisconsin fully exempts Social Security benefits from state income tax, regardless of your total income. This is a significant benefit for retirees — a household receiving $30,000 or $40,000 in annual Social Security payments pays zero Wisconsin income tax on that income. This stands in contrast to Minnesota, which taxes Social Security for higher-income residents, and makes Wisconsin more competitive as a retirement destination for Social Security-dependent households.

Military Retirement Pay: Fully Exempt

Wisconsin fully exempts military retirement pay from Wisconsin income tax. Veterans receiving pension income from any branch of the United States military pay no Wisconsin state income tax on those pension payments. This exemption, combined with the Social Security exemption and the capital gains exclusion, makes Wisconsin reasonably tax-friendly for many military retirees.

Other Pension and Retirement Income

Unlike Iowa (which exempts all retirement income for those 55+) or Illinois (which exempts virtually all retirement income), Wisconsin does not provide a blanket retirement income exemption. Pension income from private employers, 401(k) withdrawals, and IRA distributions are generally taxed as ordinary income in Wisconsin at standard bracket rates. Wisconsin public employee pensions (Wisconsin Retirement System) are also taxable.

Retirement Income Tax Summary

Retirees whose income consists primarily of Social Security and long-term capital gains will find Wisconsin relatively attractive. Retirees with large pension or 401(k) distributions — particularly those from states like Illinois or Iowa that exempt such income — may find Wisconsin comparatively less favorable for that income type.

Wisconsin Property Tax: High by National Standards

Wisconsin's property tax is consistently among the highest effective rates in the Midwest and the country. The average effective property tax rate across the state is approximately 1.73% of market value — well above the national average of about 1.1% and significantly higher than Minnesota (~1.02%) or Iowa (~1.57%).

Sample Annual Property Tax Estimates

Why Are Wisconsin Property Taxes High?

Wisconsin's high property taxes reflect heavy reliance on property tax revenue to fund local government services and K-12 schools. Wisconsin has historically kept state income and sales taxes from rising dramatically by leaning on the property tax base instead. For homeowners — particularly those in urban areas — this creates a notable annual cost that must factor into total Wisconsin tax burden calculations.

Property Tax Relief Programs

Wisconsin offers a Homestead Tax Credit for lower-income residents (household income under approximately $24,680 for 2026) to offset property tax burdens. The credit is income-tested and phases out as income rises. Elderly and disabled residents may also qualify for additional relief programs through the Wisconsin Department of Revenue. Veterans may be eligible for property tax exemptions under certain conditions.

No Local Income Tax

One offsetting factor: Wisconsin cities, counties, and municipalities do not levy local income taxes. Unlike Ohio (where many cities charge 2–2.5% city income taxes) or Michigan (where cities like Detroit levy local income taxes), Wisconsin residents pay only state-level income tax. The lack of a local income tax somewhat offsets — though does not eliminate — the higher property tax burden.

Wisconsin vs. Minnesota: Side-by-Side Tax Comparison

Wisconsin and Minnesota are neighboring states with similar climates, economies, and demographics — yet their tax systems differ significantly in ways that matter for high-income earners, investors, and retirees. Here is a direct comparison:

Income Tax Rates

Capital Gains

Retirement Income

Property Tax

Estate Tax

Bottom Line: Who Does Better in Wisconsin vs. Minnesota?

Wisconsin is better for: High-income investors with significant long-term capital gains (60% exclusion vs. Minnesota's no-exclusion 9.85% rate is a huge difference); Social Security recipients; those with estates approaching or over $3M (Wisconsin has no estate tax); residents who want lower income taxes than Minnesota without fully leaving the Midwest.

Minnesota is better for: Homeowners who prioritize low property taxes (Minnesota's ~1.02% effective rate is well below Wisconsin's 1.73%); moderate-income retirees who don't have large investment gains; residents in Minneapolis-area suburbs who value public services funded by the property tax system.

Wisconsin Sales Tax, No Estate Tax, and Key Planning Considerations

Sales Tax: 5% State + Local

Wisconsin's state sales tax rate is 5%, among the lower state rates in the country. Most Wisconsin counties add a 0.5% county sales tax, resulting in a 5.5% combined rate in most areas. Some localities may have additional sales tax for specific purposes (stadium taxes, transit, etc.) that can push rates slightly higher.

A notable difference from many neighboring states: Wisconsin taxes most grocery purchases at the standard sales tax rate. This is unlike Minnesota and Iowa, which exempt unprepared groceries. For families with significant grocery spending, this creates a meaningful cost difference. Prescription drugs are exempt from Wisconsin sales tax.

No Wisconsin Estate Tax

Wisconsin does not have a state estate or inheritance tax. For residents with significant assets, this is a substantial advantage over Minnesota (which taxes estates above $3 million at 13–16%) and Oregon (which taxes estates above $1 million). A Wisconsin resident with a $5 million estate owes no state estate tax — the same estate in Minnesota would face approximately $200,000–$300,000 in state estate taxes. For high-net-worth families, the absence of a Wisconsin estate tax is a meaningful financial planning consideration.

Key Tax Planning Considerations for Wisconsin Residents

• Maximize long-term capital gains treatment: The 60% exclusion on long-term gains is Wisconsin's most valuable tax break for investors. Holding appreciated assets over 12 months before selling can reduce your state tax rate on gains from 5.30%–7.65% to an effective 2.12%–3.06%.
• Standard deduction phase-out: If your income exceeds $15,950 (single) or $22,790 (MFJ), your Wisconsin standard deduction is being reduced. Consider whether itemizing Wisconsin deductions — including mortgage interest, charitable contributions, and property taxes paid — produces a better result than the reduced standard deduction.
• Social Security strategy: Wisconsin's full Social Security exemption means your Social Security benefits do not drive up your Wisconsin tax bill, regardless of your other income. This contrasts with Minnesota, where high-income Social Security recipients face state tax on their benefits.
• Property tax as an offset: Wisconsin's high property taxes are often deductible for those who itemize. If you pay $8,000–$12,000/year in Wisconsin property taxes, incorporating those deductions into your Wisconsin itemized deduction calculation can partially offset the income tax owed.
• Retirement account withdrawals: Unlike Iowa (full retirement income exemption for age 55+) or Illinois (broad retirement income exclusion), Wisconsin taxes 401(k) and IRA withdrawals as ordinary income. Roth conversion strategies completed before age 65 and Wisconsin retirement can be effective for reducing future taxable distributions.
