This guide explains federal and Wisconsin state tax obligations for 2025–2026, including quarterly payments, eligible deductions, retirement contributions, health insurance, and practical strategies to reduce tax liability. By following these best practices, Wisconsin freelancers and small business owners can keep more of their earnings and avoid costly mistakes.

Understanding Wisconsin Self-Employed Taxes

Self-employed individuals pay taxes at both federal and state levels. These include federal self-employment taxes for Social Security and Medicare and Wisconsin state income tax on net earnings.

Federal Self-Employment Taxes

Federal self-employment tax includes Social Security and Medicare contributions. It applies to net earnings from self-employment, calculated as total business income minus allowable business expenses.

• Social Security tax: 12.4% on the first $168,600 of net income (2025)
• Medicare tax: 2.9% on all net earnings
• Additional Medicare tax: 0.9% on income exceeding $200,000 for single filers or $250,000 for married couples filing jointly

Half of the self-employment tax is deductible from your federal taxable income. Accurate recordkeeping is essential for calculating your self-employment tax properly.

Wisconsin State Income Taxes

Wisconsin imposes a progressive income tax on net earnings from self-employment. For 2025, the tax brackets for single filers are:

Taxable Income (Single)	Tax Rate
$0 – $13,810	3.54%
$13,811 – $27,630	4.65%
$27,631 – $304,170	6.27%
Over $304,170	7.65%

Married couples filing jointly generally double these thresholds. Knowing your tax bracket helps you plan quarterly payments and anticipate your total tax liability.

Estimated Quarterly Payments

Wisconsin self-employed individuals must make estimated tax payments to both the IRS and the Wisconsin Department of Revenue (DOR) to avoid penalties.

• Federal estimated payments: April 15, June 15, September 15, January 15 of the following year
• Wisconsin estimated payments: Same deadlines as federal

Estimated payments are calculated using IRS Form 1040-ES and Wisconsin Form 1-ES. Payments are based on expected income, deductions, and credits.

Practical tip: If you need cash for estimated taxes, Beem Everdraft™ provides instant advances up to $1,000 to help meet deadlines. Learn more here.

Calculating Net Income for Wisconsin Self-Employment Taxes

Your taxable income for Wisconsin self-employment taxes is based on net earnings:

Total Business Income minus Allowable Business Expenses = Net Taxable Income

Business Income

Include:

• Payments for freelance work or consulting
• Income from selling goods or services
• Rental income from business property
• Royalties or licensing fees

Exclude personal gifts, loans, and reimbursements that are already accounted for.

Deductible Business Expenses

Wisconsin follows federal guidelines for business deductions. Common Wisconsin tax deductions for freelancers include:

• Office supplies and equipment
• Home office expenses (portion of rent, utilities, internet)
• Business travel, meals, and mileage
• Marketing, advertising, and website costs
• Professional fees such as legal, accounting, or consulting services
• Health insurance premiums for self-employed individuals

Tracking all deductions can reduce both federal and Wisconsin taxable income.

Sales Tax Requirements for Wisconsin Freelancers

Freelancers and self-employed individuals in Wisconsin who sell goods or certain taxable services must comply with state sales tax laws. Collecting and remitting the correct amount of sales tax is not optional—failure to comply can lead to penalties, interest, and audits. Understanding the rules helps ensure you stay on the right side of the law while avoiding unnecessary stress.

State and Local Sales Tax Rates

• State Sales Tax: Wisconsin has a statewide sales tax rate of 5%, which applies to most tangible goods and some services sold by freelancers and small businesses.
• Local Sales Tax: Certain counties may impose an additional 0.5–0.6% tax. The combined rate depends on the location where the sale occurs, so it’s important to verify local rates.

Tip: Always confirm the exact sales tax rate for the area where you conduct business to ensure accurate collection.

Who Must Register

Any freelancer or small business selling taxable goods or services must register with the Wisconsin Department of Revenue (DOR). This includes:

• Sole proprietors, LLCs, or corporations
• Online sellers shipping products to Wisconsin residents
• Service providers offering taxable services, such as certain consulting or repair work

Tip: Register your business before your first taxable sale to avoid penalties for unregistered activity.

Filing and Payment Requirements

Sales tax returns in Wisconsin must be filed and taxes remitted according to your business’s revenue:

• Monthly filing: Required for businesses with higher sales volumes
• Quarterly filing: Allowed for smaller businesses with moderate sales
• Annual filing: Permitted for very small businesses with minimal taxable sales

Filing can be completed online through the Wisconsin DOR, which simplifies submission and payment.

Tip: Keep detailed records of all sales, exempt sales, and taxes collected to ensure accurate reporting.

Consequences of Non-Compliance

Failure to collect, report, or remit sales tax can result in:

• Penalties for late or missed payments
• Interest on unpaid taxes
• Possible audits or additional assessments

Tip: Set aside the sales tax you collect in a separate account to avoid accidentally spending funds needed for payment. Timely filing and remittance are the best ways to stay compliant.

Best Practices for Freelancers

• Verify rates for each location: Include both state and local taxes.
• Register your business early: Avoid fines for unregistered activity.
• Keep accurate records: Track sales, exemptions, and payments.
• File on time: Follow monthly, quarterly, or annual schedules based on your revenue.
• Use online tools: Accounting software or the Wisconsin DOR online portal can simplify filing and payment.

By understanding and following Wisconsin’s sales tax requirements, freelancers can remain compliant, avoid penalties, and focus on growing their business without unnecessary financial risks.

Recordkeeping Tips for Wisconsin Self-Employed Individuals

Accurate records simplify tax filing, maximize deductions, and protect against audits.

What to Track

• All income: bank statements, invoices, 1099 forms
• Expenses: receipts for business purchases
• Mileage and travel logs
• Contracts and agreements for freelance or consulting work

Common Wisconsin Self-Employed Tax Mistakes

Self-employment offers freedom, but it also comes with tax responsibilities that can be tricky for freelancers, consultants, and small business owners in Wisconsin. Many self-employed individuals make mistakes that increase their tax liability or trigger penalties. Recognizing these common pitfalls can help you stay compliant and save money.

Underestimating Quarterly Tax Payments

Self-employed workers are required to make quarterly estimated tax payments to both the IRS and the Wisconsin Department of Revenue. Waiting until tax season to pay the full amount can lead to penalties and interest.

Why it happens: Income can fluctuate month to month, and many self-employed individuals assume they can “catch up” at the end of the year. Without regular tracking, it’s easy to underpay.

Tip: Review income mid-quarter and adjust payments accordingly to avoid penalties and large tax bills at filing time.

Mixing Personal and Business Expenses

Using the same bank account or credit card for both personal and business transactions complicates recordkeeping and can weaken your deduction support.

Consequences:

• Harder to justify deductions during an audit
• Increased preparation time when filing taxes
• Higher risk of errors

Tip: Open separate bank accounts and credit cards for business use. Track all business-related expenses and receipts meticulously.

Missing Deductions for Home Office or Vehicle Expenses

Many Wisconsin self-employed taxpayers overlook deductions they are eligible for, including:

• Home office expenses: Deduct a portion of rent, mortgage interest, utilities, and insurance for the space used exclusively for business.
• Vehicle expenses: Deduct either standard mileage or actual costs for business-related travel, such as client visits or deliveries.

Tip: Keep accurate logs of your home office square footage and vehicle mileage to maximize deductions and reduce taxable income.

Filing Late or Inaccurately

Late or incorrect filings can trigger penalties, interest, and missed refunds. Common errors include:

• Incorrectly reporting business income or expenses
• Forgetting to include self-employment tax on Schedule SE
• Miscalculating deductions or credits

Tip: Prepare your returns early, double-check calculations, and consider using accounting software or consulting a tax professional familiar with Wisconsin self-employment rules.

Ignoring Sales Tax Obligations

If your business sells taxable goods or services in Wisconsin, you must:

• Register with the Wisconsin Department of Revenue
• Collect the correct sales tax from customers
• File returns and remit taxes on time

Consequences: Failure to comply can result in penalties, interest, and audits.

Tip: Review state sales tax requirements annually and maintain accurate sales records to ensure compliance.

How to Avoid These Mistakes

• Stay organized: Keep clear, detailed records of income, expenses, and receipts.
• Track quarterly payments: Regularly estimate and pay federal and state taxes.
• Separate finances: Use dedicated accounts for business transactions.
• Claim all eligible deductions: Include home office, vehicle, retirement contributions, and health insurance.
• Follow sales tax rules: Register properly, collect accurately, and file on time.

By avoiding these common mistakes, self-employed Wisconsinites can reduce tax liability, prevent penalties, and make tax season far less stressful.

Retirement Planning for Wisconsin Freelancers

Contributing to retirement accounts reduces taxable income while planning for the future. Popular options include:

• SEP IRA: Contribute up to 25% of net earnings, maximum $66,000 in 2025
• Solo 401(k): Contribute up to $66,000, plus catch-up contributions for those over 50
• Traditional IRA: Contribute up to $6,500 in 2025, deductible depending on income

Retirement contributions reduce both federal and Wisconsin taxable income.

Health Insurance Deductions

Self-employed individuals can deduct premiums for health, dental, and long-term care insurance for themselves, spouses, and dependents. Wisconsin follows federal rules, and deductions apply even without itemizing.

Wisconsin Tax Credits for Freelancers

Wisconsin offers several tax credits for self-employed individuals:

• Child Tax Credit: For qualifying dependents
• Education Credits: For tuition or student loan interest
• Renewable Energy Credits: For business investments in energy-efficient equipment

Tax credits reduce your tax liability directly and are often more valuable than deductions.

1. Calculate net income using Schedule C
2. Determine federal self-employment tax using Schedule SE
3. Apply deductions and credits
