Wisconsin Tax Brackets
The state of Wisconsin has a progressive income tax system, which means that residents are taxed at different rates depending on their income level. Understanding Wisconsin's tax brackets is crucial for individuals and businesses operating within the state to effectively plan their finances and ensure compliance with tax regulations.
Wisconsin Income Tax Brackets and Rates

As of my last update in January 2023, Wisconsin has four income tax brackets, each with its own tax rate. These brackets are adjusted annually to account for inflation and cost-of-living changes. The current tax rates and brackets are as follows:
| Tax Bracket | Tax Rate | Income Range |
|---|---|---|
| 1. | 4.0% | Up to $12,549 for Single filers Up to $18,823 for Married Filing Jointly |
| 2. | 5.0% | $12,550 to $37,649 for Single filers $18,824 to $56,473 for Married Filing Jointly |
| 3. | 6.0% | $37,650 to $240,000 for Single filers $56,474 to $320,000 for Married Filing Jointly |
| 4. | 7.65% | Over $240,000 for Single filers Over $320,000 for Married Filing Jointly |

These tax brackets and rates apply to Wisconsin residents' taxable income, which is the income earned after deductions and exemptions are applied. It's important to note that Wisconsin offers various deductions and credits that can reduce the taxable income and potentially move an individual or business to a lower tax bracket.
Wisconsin Tax Deductions and Credits

Wisconsin provides several deductions and credits to ease the tax burden on its residents and businesses. These deductions and credits can significantly impact the amount of tax owed and potentially move taxpayers to a lower tax bracket.
Standard Deduction
Wisconsin offers a standard deduction based on filing status. For the 2023 tax year, the standard deduction amounts are:
- Single: $4,650
- Married Filing Jointly: $9,300
- Head of Household: $7,200
Taxpayers can choose to claim the standard deduction or itemize their deductions, whichever results in a lower tax liability.
Itemized Deductions
Individuals and businesses can also deduct certain expenses, such as medical and dental costs, state and local taxes, charitable contributions, and mortgage interest. Itemizing deductions can be beneficial for those with significant expenses in these areas.
Tax Credits
Wisconsin offers a range of tax credits to encourage specific behaviors or support certain industries. Some common tax credits include:
- Earned Income Tax Credit (EITC): This credit provides a refund for low- to moderate-income working individuals and families.
- Child and Dependent Care Credit: Taxpayers can claim a credit for expenses related to childcare or dependent care.
- Energy Efficiency Credit: Wisconsin offers a credit for homeowners who invest in energy-efficient improvements.
- Research and Development Credit: Businesses engaged in research and development activities can claim this credit.
These credits can provide significant tax savings and are worth exploring for eligible taxpayers.
Wisconsin Tax Filing and Payment
Wisconsin residents and businesses must file their state income tax returns annually, typically by April 15th. The state offers both electronic and paper filing options. The Wisconsin Department of Revenue provides detailed guidelines and resources for tax preparation and filing.
Taxpayers can choose to pay their taxes in full by the filing deadline or opt for an installment plan. Late payments or non-payment can result in penalties and interest charges.
Business Tax Considerations
Businesses operating in Wisconsin, including corporations, partnerships, and sole proprietorships, are subject to state taxes. The tax rates and brackets for businesses can vary depending on the entity type and industry. It’s essential for businesses to understand their specific tax obligations and comply with the relevant regulations.
Wisconsin also offers various incentives and tax credits for businesses, such as the Manufacturing and Agriculture Credit and the High Technology Job Creation Tax Credit. These incentives aim to promote economic growth and job creation within the state.
