Freelance Writer Taxes in Wisconsin - 2026 Guide

Updated for 2026 (Filing 2025 Taxes)

Tax Essentials for a Freelance Writer in Wisconsin

From crafting compelling content about the Dells to reporting on the Packers, freelance writing in Wisconsin offers unique opportunities – and unique tax responsibilities. As a self-employed writer, understanding these obligations is crucial for financial health.

The federal government requires all freelance writers earning over $400 in net profit to report income and pay self-employment taxes. This is done primarily through Schedule C (Profit or Loss from Business) filed with Form 1040. Accurate record-keeping throughout the year is essential to maximize deductions and ensure compliance.

How Wisconsin Handles Gig Worker Taxes

As a resident of Wisconsin, a state income tax return is required regardless of income level. Wisconsin utilizes a graduated income tax system, meaning the tax rate increases as income increases. For the 2025 tax year, self-employed individuals will primarily use Form 1040-ES and Schedule 1 to calculate and pay estimated taxes throughout the year, and Form 1040 with Schedule 1 and Schedule Z to file their annual return. The primary form for reporting self-employment income and calculating Wisconsin income tax is Form 1040-ES, along with Schedule 1 and Schedule Z. Wisconsin also offers a variety of credits and deductions that can reduce your tax liability, such as the Earned Income Tax Credit and the Wisconsin Homestead Credit. It’s important to note that Wisconsin taxes are based on your federal adjusted gross income (AGI), so accurate federal reporting is paramount. Wisconsin also has specific rules regarding the deductibility of certain expenses, which may differ from federal rules. For example, the state may have different limitations on deductions for business meals or entertainment. Staying informed about these nuances is vital. Wisconsin’s Department of Revenue provides comprehensive resources and guidance for self-employed individuals.

Key Tax Deductions for Home-Based Freelance Writers

• Home Office Deduction: To qualify for the home office deduction, the space must be used exclusively and regularly for business. “Exclusive use” means that portion of your home is only used for work – no guest rooms doubling as offices. “Regular use” means consistent, ongoing use for business activities. You can calculate the deduction using the simplified method ($5 per square foot, up to 300 square feet) or the actual expense method (calculating a percentage of your mortgage/rent, utilities, etc., based on the square footage used for business).
• Hardware & Software: The cost of computers, cameras, printers, and essential software subscriptions (like Adobe Creative Cloud, website hosting, or grammar checking tools) used for your writing business are generally deductible. For items with a useful life of more than one year, depreciation or Section 179 expensing may apply.
• Internet & Phone Bill: If you use your internet and phone for both personal and business purposes, you can deduct the percentage attributable to business use. Keep detailed records of how you allocate these expenses.

Note on Mileage: As a home-based worker, mileage deductions are less common. However, you can claim mileage for occasional trips to meet with clients, attend industry events, or run business-related errands. Keep a detailed mileage log.

The 15.3% Self-Employment Tax Explained

The 15.3% self-employment tax covers both Social Security and Medicare contributions. Employees have these taxes withheld from their paychecks, but as a freelancer, you are responsible for paying both the employer and employee portions. You can deduct one-half of your self-employment tax from your gross income when calculating your adjusted gross income (AGI).
