This guide is designed for individuals, sole proprietors, and small business owners who must file or amend a 2016 return.

Filing a state return after the original due date might involve extra steps, but it can be manageable with the right resources and guidance. Whether you’re working alone or with a tax professional, this article provides all the tools and context you need to file accurately and confidently for the 2016 tax year.
Wisconsin’s state income tax system is structured to collect taxes based on the income you earn while living or working there. If you lived in Wisconsin for all or part of 2016—or earned income from Wisconsin sources—you may be required to file a return, depending on your income level and filing status. Understanding how the system works is the first step in preparing an accurate 2016 return.
Wisconsin uses a progressive income tax structure. This means your income is taxed in tiers, with higher earnings taxed at higher rates. Four income brackets for the 2016 tax year ranged from 4.00% to 7.65%. These rates applied to taxable income after adjustments and deductions were considered. Unlike a flat tax system, this approach means your state return reflects the effect of your income level and any credits or deductions you qualify for.
Your federal return plays a critical role in filing your Wisconsin taxes because the state uses your federal adjusted gross income (AGI) as the starting point for its calculations. From there, you’ll apply state-specific additions, subtractions, and credits. This connection between federal and state taxes makes completing your federal income tax return essential, even if you don’t plan to submit it. Hence, your Wisconsin tax filing is accurate and complete.
Whether you were required to file a Wisconsin tax return for 2016 depends on your gross income, filing status, age, and residency status. The Wisconsin Department of Revenue established specific income thresholds for different types of taxpayers. If your income for 2016 met or exceeded these thresholds, you were required to file—even if you didn’t owe any tax.
If your 2016 gross income met or exceeded the following amounts, you needed to file a state return:
These figures were based on printed instructions found in the 2016 tax forms provided by the state.
You may have had to file even if your income fell below the thresholds. Common reasons include:
In each case, filing a return was necessary to remain compliant, qualify for tax benefits, or avoid interest and penalties. If you're unsure whether your 2016 income met the filing requirement, consider reviewing the original form instructions or consulting a tax professional for guidance.
The Wisconsin Department of Revenue provided several tax forms for the 2016 tax year, depending on your income sources, residency status, and filing complexity. Choosing the correct form is essential to ensure accurate filing and to avoid unnecessary delays or rejections. You can download the official 2016 forms and instructions here.
Depending on your situation, you may also need to include one or more of the following forms:
All 2016 forms and instructions are available for download on the Wisconsin Department of Revenue’s website. You can also request printed copies by contacting their office directly or visiting a local DOR office if you prefer in-person assistance. Correct documentation ensures smooth processing and helps avoid unnecessary follow-up from the state.
Even though the 2016 tax year is behind us, it’s essential to understand the legislative and policy changes that were in effect at that time—especially if you’re filing late, amending a return, or responding to an audit. The Wisconsin Department of Revenue implemented several updates that impacted deductions, credits, and eligibility criteria.
For the 2016 tax year, Wisconsin adjusted the standard deduction amounts for inflation. This resulted in slightly higher deductions for most filing statuses, including married filing jointly, single, and head of household. These changes lowered taxable income for many residents and provided modest tax savings.
New in 2016, Wisconsin allowed contributions made to Achieving a Better Life Experience (ABLE) accounts to be subtracted from income. These accounts are designed to support individuals with disabilities by offering tax-advantaged savings. Taxpayers who contributed to a qualifying ABLE account could subtract up to the contribution amount from their Wisconsin income, reducing their overall tax liability.
The state introduced the Business Development Credit, which encouraged job creation and investment within Wisconsin. To qualify, businesses had to be certified by the Wisconsin Economic Development Corporation (WEDC). The credit was based on employee wages, training expenditures, and real or personal property investments.
While minor, several other provisions changed for 2016, including updates to depreciation rules, tax-exempt savings programs, and alignment with specific federal tax code adjustments. If you operated a business or claimed less common credits, it is recommended that you review the 2016 instructions or speak with a tax professional.
Understanding these updates ensures you correctly calculate your liability or refund and take advantage of every opportunity to lower your tax bill for that year.
Filing your 2016 Wisconsin state return requires careful preparation and attention to detail. Follow these steps to ensure your return is complete, accurate, and filed correctly—whether submitting a late return or amending a previously filed one.
Before you begin, collect all necessary documentation. Having everything ready will help you avoid delays and mistakes.

Wisconsin’s tax system relies on your federal income tax return information, notably your adjusted gross income (AGI). Even if you’re not submitting a federal return for 2016, it’s essential to prepare one anyway to ensure the accuracy of your Wisconsin filing.
If you were not required to file federally, you must still provide a worksheet showing all income sources, deductions, and adjustments to calculate your state AGI. This substitute calculation should follow the same structure used by the IRS for 2016 and be retained with your records.
You’re ready to begin the state portion with your federal return complete.

Although the original 2016 filing and payment deadline was April 18, 2017, any unpaid taxes are still subject to penalties and interest:
To avoid further accumulation of fees, submit your payment as soon as possible, even if you are filing under an extension or correcting a past error.

Before you file your 2016 Wisconsin state return, take a few minutes to review your documents and forms. A simple mistake or missing item could delay your refund, trigger a notice from the Department of Revenue, or result in interest and penalties.
Use the checklist below to confirm that your return is complete:
Completing this checklist will help ensure that your return is accepted without delays and that you fully comply with state filing requirements. Before you file, visit the Wisconsin Department of Revenue homepage for more official guidance, updates, and access to online services.
If you haven’t filed your 2016 Wisconsin tax return by the April 18, 2017, deadline, you can still file it. However, any tax owed may now include penalties and interest. If you’re due a refund, there’s typically a four-year window to claim it. File as soon as possible to minimize fees and ensure compliance with the Wisconsin Department of Revenue.
Yes. Wisconsin allows you to claim a refund for up to four years from the original due date, which means you had until April 18, 2021, to claim a 2016 refund. If you didn’t meet that deadline, the refund may be forfeited. If you’re within the deadline and eligible, file using the proper forms and supporting documentation.
You may still file jointly if you were legally married on December 31, 2016, even if you or your spouse moved during the year. However, if either of you was a part-year resident or nonresident, you must file using Form 1NPR to allocate income earned inside and outside Wisconsin properly. Always include your correct addresses and residency periods.
You likely don't need to file if you had no income and didn’t meet any special filing conditions—such as owing penalties, claiming credits, or being a dependent with investment income. However, filing may still be beneficial if you qualify for refundable credits like the homestead credit. Review the official 2016 instructions or consult a tax professional if unsure.
If the IRS adjusts your 2016 federal return through an audit, you must notify the Wisconsin Department of Revenue within 90 days. You must file an amended state return or mail a copy of the final federal audit report. Any federal adjusted gross income changes can impact your Wisconsin tax calculation and balance due.
Most major e-filing platforms no longer support 2016 returns. However, you may still file electronically through Wisconsin’s My Tax Account or authorized third-party software that supports back-year filings. Alternatively, you can download the 2016 forms and file by mail. Follow the 2016 instructions and verify mailing addresses for your specific situation.
You should keep your 2016 tax records for at least four years after the return’s due date. That includes your state return, federal return, income documents, receipts, and any correspondence with the Wisconsin Department of Revenue. Keeping these files ensures you're prepared in case of an audit, refund claim, or dispute about taxes owed or paid.
