Wisconsin Tax Return for 2023: What Deductions Can You Claim?

Filing your 2023 Wisconsin tax return allows you to reduce what you owe legally and efficiently. Deductions directly impact your taxable income, lowering your overall tax burden when applied correctly. Many Wisconsin residents overlook valuable deductions simply because they don’t fully understand what they’re eligible to claim. This guide aims to simplify that process and help you keep more of your income.

Tax deductions reduce the portion of your income subject to taxation, leading to potential savings at every income level. For example, contributing to a college savings account or HSA can reduce your taxable income in Wisconsin. These deductions are not automatic—you must identify, qualify for, and report them properly. Filing accurately ensures you benefit from every credit and deduction Wisconsin allows in 2023.

This article will walk you through Wisconsin-specific deductions and commonly missed opportunities that could lower your taxes. We’ll also explain how to navigate Wisconsin tax forms like Form 1 and Schedule SB effectively. By understanding your eligibility and the process, you’ll file smarter and potentially owe less. Let’s break down the deductions Wisconsin offers and how to claim them correctly for 2023.

Wisconsin-Specific Deductions on Your Tax Return

If you're completing your Wisconsin tax return for 2023, it's essential to understand the state-specific deductions that can reduce your income tax burden. These deductions apply only to Wisconsin residents and can significantly impact your final tax return. Below are some key deductions that individuals may be eligible to claim, along with tips on using them effectively during filing.

College Savings Account Contributions

Contributions to a Wisconsin 529 College Savings Program (such as Edvest or Tomorrow's Scholar) may be deductible on your Wisconsin income tax return.

• For the 2023 tax year, individuals can deduct up to $3,860 per beneficiary.
  
  
• Only contributions made during the calendar year count, and the deduction is limited to contributions made by the account owner.
  
  
• Review the latest IRS instructions and Wisconsin Department of Revenue guidelines before claiming.

Tuition and Higher Education Expenses

Wisconsin offers a deduction for tuition paid to colleges, universities, and technical schools.

• Qualified tuition expenses for you, your spouse, or dependents can be deducted if the institution is accredited and located in Wisconsin.
  
  
• The maximum deduction is typically $6,974 for each student, but this may vary by year—check current tax forms and income limits.
  
  
• You'll need documentation like 1098-T forms and proof of payment when filing.

Retirement Contributions (Wisconsin-Specific Adjustment)

While many retirement contributions are handled federally, Wisconsin allows specific subtractions for certain retirement benefits.

• If you’re receiving retirement income from a qualified plan, you may be eligible for a Wisconsin subtraction depending on your age and income.
  
  
• Some retirement benefits may be subject to a complete subtraction for individuals over age 65 with income under $15,000 ($30,000 for married couples).
  
  
• Be sure to review Schedule SB and the instructions for Form 1 to determine eligibility.

Capital Loss Subtraction (State-Level Adjustment)

Wisconsin treats capital losses differently from the federal IRS.

• If your federal capital loss exceeds $500, Wisconsin limits the deduction to $500 per year.
  
  
• However, any unused loss above $500 may be carried forward for future use on your Wisconsin income tax return.
  
  
• Use Wisconsin Schedule WD to calculate allowable deductions and carryovers.

To complete your Wisconsin income tax return accurately, it’s essential to download the correct income tax forms, read all filing instructions carefully, and review your eligibility for state-level deductions. If you qualify for the IRS Free File Program or Wisconsin’s Direct File option, you can file online at no cost. These tools also offer built-in checks to help individuals avoid errors. For more detailed information, visit the Wisconsin Department of Revenue website or consult a tax professional to address any outstanding questions.

Commonly Overlooked Deductions

Many Wisconsin taxpayers miss valuable deductions simply because they’re lesser-known or misunderstood. Below is a breakdown of some commonly overlooked tax deductions and credits that could significantly reduce your 2023 Wisconsin tax bill if you qualify.

Homestead Credit: A Lifeline for Low- to Moderate-Income Renters and Homeowners

• This credit is available to full-year Wisconsin residents who pay rent or property taxes on their primary residence.
  
  
• Eligibility is based on income (generally less than $24,680 for 2023) and the amount of property tax or rent paid.
  
  
• Even if you owe no income tax, you may still receive a refund through this credit.
  
  
• Claim it using Schedule H or H-EZ, depending on your situation.

Earned Income Credit (Wisconsin EIC): Boosting Refunds for Working Families

• The Wisconsin EIC supplements the federal Earned Income Tax Credit and is available to low- and moderate-income working individuals and families with qualifying children.
  
  
• The amount depends on your income level and the number of qualifying dependents.
  
  
• Unlike the federal credit, you must have claimed the federal EIC to qualify for the state version.
  
  
• It's a refundable credit, meaning you can receive money back even if you owe no tax.
  
  

Job Search Expenses: Still Deductible in Specific Cases

• While the IRS eliminated unreimbursed job search deductions for most taxpayers, some job-related expenses (e.g., travel for a new job in a different state) may still qualify under moving expenses for Armed Forces members.
  
  
• Wisconsin does not conform to all federal changes, so reviewing the state’s treatment of unreimbursed employee expenses can be worth your time.

Dependent Care Expenses: Wisconsin's Child and Dependent Care Credit

• If you paid for child care so you could work or look for work, you may qualify for a state tax credit even if your federal credit was limited or phased out.
  
  
• Use Schedule DC to claim this credit, which could apply to daycare, preschool, or after-school care expenses.
  
  

Health Savings Account (HSA) Contributions: Pre-Tax Savings Still Count

• Wisconsin does not conform to the federal tax treatment of HSAs, so contributions are not automatically deductible for Wisconsin state taxes.
  
  
• However, if you contributed to an HSA and claimed a deduction on your federal return, you must add it to your Wisconsin return using Schedule I.
  
  
• This means your federal tax savings from HSA contributions don’t apply at the state level, a commonly overlooked pitfall.

Reviewing your return for these often-missed deductions and credits could mean the difference between a tax bill and a refund. Don’t assume your tax software or preparer is catching everything—proactively checking these items could save you hundreds or even thousands.

How to Claim Deductions on Your Tax Return

Claiming deductions on your Wisconsin tax return involves more than just filling in a few boxes — it requires choosing the correct forms, understanding the rules behind each deduction, and maintaining documentation that backs up every claim. Here’s a clear, structured breakdown of properly claiming deductions on your 2023 Wisconsin income tax return.

Start with the Right Base Form: Wisconsin Form 1

• What it is: Form 1 is the primary individual income tax form for full-year Wisconsin residents.
  
  
• Why it matters: This is the foundation of your return — all deductions flow through this form, either directly or via supplemental schedules.
  
  
• Tip: Ensure you're using the 2023 version of Form 1; older forms won’t reflect the most recent deduction thresholds or rules.

Use Schedule SB for Subtractions from Income

• What it is: Schedule SB (Subtractions from Income) is where most Wisconsin-specific deductions are claimed.
  
  
• Key uses: This is where you'll report deductions such as contributions to a Wisconsin 529 college savings plan, specific retirement account contributions, and health savings account deductions.
  
  
• Important note: Not all federal deductions carry over — Schedule SB is explicitly tailored to Wisconsin tax law.

Know When to Use Additional Schedules

• Form 1NPR: Required if you’re a part-year resident or nonresident of Wisconsin.
  
  
• Schedule WD: For capital gain/loss deductions.
  
  
• Schedule I: If you need to adjust your federal adjusted gross income due to differences between federal and Wisconsin law.

Keep Detailed Records to Support Every Deduction

• Why it's essential: The Wisconsin Department of Revenue may request verification of deductions. Vague or undocumented claims can lead to audits or denied deductions.
  
  
• Examples of records to retain:
  
  
  
  • Receipts for charitable donations or medical expenses (if itemizing)
    
    
  • 1099-SA forms for HSA contributions and withdrawals
    
    
  • Proof of tuition paid (e.g., Form 1098-T or school statements)
    
    
  • Documentation of IRA or retirement contributions
    
    
• Pro tip: Store digital and paper versions of all tax documents for at least 7 years, particularly if you claim fewer standard deductions.

Double-Check and File Correctly

• Review line-by-line: Mistakes often happen on subtraction schedules, where incorrect entries can skew your entire return.
  
  
• E-file for accuracy: The Wisconsin e-file system performs many checks automatically, reducing the chance of rejected returns or errors.
  
  
• Don’t rush: Missing one line item on a schedule could mean leaving hundreds of dollars on the table.

Claiming deductions correctly on your Wisconsin tax return isn’t just about reducing what you owe — it’s about ensuring every line and every claim can stand up to scrutiny. Take the time to file smart, not just fast.

Itemized Deductions and Their Impact on Your Tax Return 

Itemized deductions can significantly lower your Wisconsin taxable income—but only if they exceed the standard deduction and are correctly documented. Here's what you need to know to determine if itemizing is the smarter option for your 2023 Wisconsin tax return:

• Mortgage Interest (A Major Deduction for Homeowners): If you paid interest on a qualified home loan in 2023, you may be able to deduct it. This includes interest on your primary home and, in some cases, a second home. This deduction can be especially valuable for new homeowners with high-interest payments early in their mortgage term.
  
  
• Medical and Dental Expenses: Only the Excess Counts
  You can deduct unreimbursed medical expenses that exceed 7.5% of your adjusted gross income (AGI). This can include surgeries, prescriptions, mental health services, and long-term care premiums, but only the portion above the threshold counts.
  
  
• State and Local Taxes (SALT): You may deduct up to $10,000 in a combination of state income, sales, and property taxes. This can relieve Wisconsin homeowners or those in higher-taxed counties, though the cap may limit higher-income taxpayers.
  
  
• Charitable Contributions (Must Be Documented): Donations made to qualified nonprofits, religious organizations, or educational institutions can be itemized if you kept detailed receipts. This applies to both cash and property contributions made in 2023.
  
  
• Casualty and Theft Losses (Limited but Possible): These are only deductible if related to a federally declared disaster. Wisconsin residents affected by such events must keep thorough records and meet specific IRS criteria to qualify.
  
  
• Miscellaneous Deductions (Mostly Gone, but Still Check): The Tax Cuts and Jobs Act eliminated many miscellaneous itemized deductions through 2025, but some, like gambling losses (up to winnings), are still available. Always verify with updated IRS guidance.
  
  
• Itemized vs. Standard Deduction: The standard deduction is a fixed amount—$12,950 for single filers and $25,900 for joint filers in 2023—reducing your taxable income without documentation. Itemizing only makes financial sense if your total eligible deductions exceed this amount. Use Schedule A of IRS Form 1040 and the Wisconsin Form 1 for proper reporting.

Choosing to itemize requires effort and documentation, but it can pay off if your qualified expenses are high enough. Keep receipts, use accurate forms, and consult a tax professional if unsure which path offers the best return.

Tax Credits vs. Deductions

Understanding the difference between tax credits and tax deductions is essential for lowering your overall tax bill — but these two tools work very differently. Below is a breakdown of how each functions and which Wisconsin-specific credits you might be eligible for on your 2023 return.

• Tax Credits Directly Reduce the Tax You Owe: Unlike deductions, which reduce your taxable income, tax credits reduce your actual tax liability dollar-for-dollar. For example, a $500 tax credit cuts your tax bill by $500 — regardless of your income bracket. This makes credits especially valuable for low- to moderate-income filers.
  
  
• Tax Deductions Lower Your Taxable Income: Deductions reduce the amount of income that’s subject to tax. For instance, if you earned $50,000 and claim $5,000 in deductions, the IRS will tax you on $45,000 instead. The real savings depend on your tax bracket, making deductions more beneficial for higher-income earners.
  
  
• Refundable Credits Can Lead to a Bigger Refund: Some credits are refundable, meaning if the credit exceeds your tax owed, the remaining amount is paid to you as a refund. The Wisconsin Earned Income Credit (based on your federal EIC) is refundable and especially helpful for low-income working families.
  
  
• Wisconsin’s Earned Income Credit (EIC): If you qualify for the federal Earned Income Credit, you likely qualify for Wisconsin’s version too. It’s calculated as a percentage of your federal EIC and is available only if you have at least one qualifying child and meet income limits. This credit helps boost refunds for working families.
  .
• Child and Dependent Care Credit: Wisconsin offers a nonrefundable credit for a portion of expenses paid for child or dependent care that allows you to work or look for work. This credit is based on your federal Child and Dependent Care Credit but capped by state-specific limitations and income thresholds.
  
  
• College Tuition Tax Credit: Wisconsin allows residents to claim a nonrefundable credit for tuition expenses paid to certain post-secondary institutions. This includes technical colleges, universities, and accredited private institutions, making it particularly valuable for families funding higher education.

By understanding the difference between deductions and credits — and knowing which Wisconsin-specific tax credits you can claim — you can reduce your tax burden more effectively and possibly boost your refund. Always review eligibility requirements closely or consult a tax professional to ensure you get the full benefit.

How to File Your Wisconsin Tax Return

Filing your Wisconsin tax return doesn't have to be overwhelming or expensive. If your income meets specific criteria, the IRS Free File Program offers a straightforward, no-cost way to submit your 2023 return electronically. Here's precisely how to access and use it effectively:

• Confirm You Qualify for Free File: The IRS Free File Program is available to individuals with an adjusted gross income (AGI) of $79,000 or less in 2023. If your income exceeds that, you can still use Free File Fillable Forms, which are not guided or state-compatible.
  
  
• Visit the Official IRS Free File Page: Go to irs.gov/freefile. This is the only official portal. Avoid third-party websites claiming to offer “free” filing that may charge later.
  
  
• Choose a Partnered Free File Provider: You’ll be matched with one of several IRS-approved providers (like TaxAct, FreeTaxUSA, or 1040Now) based on your income, age, and state of residence. Not all partners support Wisconsin returns, so carefully read the provider’s eligibility and state support information.
  
  
• Create an Account with the Chosen Provider: Once you've selected a partner, follow their secure link from the IRS site to create a new user account and start the guided preparation process. Access the provider via the IRS page to avoid landing on the paid version.
  
  
• Prepare Both Federal and Wisconsin Returns Simultaneously: Most Free File providers include your Wisconsin income tax return at no additional cost when filing your federal return. Follow the prompts to enter your W-2s, deductions, and credits. Check for state-specific options like the Homestead Credit or college savings deductions.
  
  
• Review, Sign, and E-File: Double-check all entries for accuracy. Most systems perform basic error checks and allow for electronic signatures using your 2023 AGI or prior-year PIN. Submit both federal and state returns securely from within the Free File software.
  
  

Taking advantage of the IRS Free File Program can simplify the filing process, eliminate filing fees, and help ensure you claim all deductions and credits you’re eligible for in Wisconsin. Be sure to start early to avoid delays and secure any refunds owed.

Filing Paper or Electronic Tax Forms

When filing your 2023 Wisconsin state tax return, choosing between paper and electronic filing can affect everything from your refund speed to your risk of error. Here's a practical comparison to help you decide what's best for your situation and tips to get the most out of e-filing.

• Faster Processing and Refunds with E-Filing: The Wisconsin Department of Revenue processes electronic returns significantly faster than paper forms—often within days, compared to weeks for mailed-in returns. If you're expecting a refund, e-filing is the quickest route to receiving your money.
  
  
• Fewer Errors and Rejections: E-filing systems automatically check for math mistakes and missing fields, significantly reducing the risk of filing errors. On the other hand, paper returns are more prone to miscalculations or skipped sections that could delay processing or lead to audits.
  
  
• Automatic Confirmation of Receipt: When you file electronically, you receive instant confirmation that your return was received. With paper returns, there’s no assurance unless you pay extra for certified mail, leaving room for uncertainty, especially close to deadlines.
  
  
• Convenient Access to Prior-Year Data: Most online filing platforms let you import prior-year tax information, saving you time and ensuring consistency. However, you'll need to manually reference and transfer prior-year details with paper forms, increasing the chance of inconsistency.
  
  
• Paper Filing May Be Necessary in Special Cases: Despite the advantages of e-filing, certain situations—like submitting amended returns or rare forms not supported electronically—may require paper submission. In those cases, expect longer wait times and consider sending your return via certified mail for proof of delivery.

Tips for a Smoother E-Filing Experience

• Use the Wisconsin e-file tool or an IRS-approved software provider to integrate state and federal filing.
  
  
• Double-check bank account and routing numbers to avoid refund delays.
  
  
• File early to avoid server congestion close to the deadline.
  
  
• Keep a PDF copy of your final submission for your records.
  
  
• Use strong, unique passwords when creating accounts on e-filing platforms to protect sensitive financial data.

Ultimately, electronic filing is faster, more secure, and less prone to errors than paper filing for most taxpayers in Wisconsin. E-filing is the most efficient and reliable option unless your situation demands paper forms.

FAQs

What are the main deductions available on my Wisconsin tax return for 2023?

‍

Wisconsin deductions for 2023 include contributions to college savings plans (Edvest or Tomorrow’s Scholar), tuition and fees, retirement contributions to IRA or 401(k) accounts, and capital loss deductions.

How do I maximize my Wisconsin tax deductions in 2023?

To maximize deductions, contribute to eligible accounts such as HSAs, IRAs, or Edvest college savings plans before the tax year deadline. Consider itemizing if your expenses (e.g., mortgage interest, medical costs) exceed the standard deduction. Claim all available credits, including the Homestead and Earned Income Credits. Keep detailed records and receipts, and use Form 1 with Schedules (like SB or WD) to ensure you capture all allowable deductions and adjustments.

Can I use the IRS Free File Program to file my Wisconsin tax return for 2023?

If your income qualifies, you can use the IRS Free File Program to prepare and e-file your federal return and access links to free Wisconsin filing options.

This can save money and ensure accurate electronic filing with both agencies.

What are the most common mistakes to avoid when claiming deductions on my Wisconsin tax return for 2023?

Common errors include failing to claim overlooked deductions like the Homestead Credit or HSA contributions, entering incorrect Social Security numbers, or using outdated tax forms. Some filers forget to attach required documentation, such as tuition or retirement contribution records. Mistakes in itemizing or choosing the wrong standard deduction can also reduce your refund or lead to audits. Double-check calculations and consult Form 1 instructions carefully.

Can I still claim deductions if I file on paper with income tax forms for Wisconsin in 2023?

You can claim all eligible deductions on a paper-filed Wisconsin tax return using Form 1 and the appropriate schedules. However, paper filing may increase the risk of manual errors or omissions and delay processing times. Be sure to include all supporting documentation and carefully complete each section. While e-filing is recommended for accuracy and speed, paper returns remain a valid and compliant filing method.
