If you lived or worked in Kansas during 2016 and didn’t file your state income tax return, this guide is for you. Many residents are surprised to learn they can still submit a late Kansas tax return, primarily if they’re owed a refund or need to resolve an outstanding issue. Filing now can help you avoid further penalties and provide you with access to state credits or overpaid taxes from that year.

Late filing can result in added interest, collection notices, or a delay in receiving money owed to you. Even if you earned very little in 2016, you may still need to file to claim a refund or document your status with the Kansas Department of Revenue. This article explains who must file, how to get the proper Kansas tax forms, and how to complete, sign, and submit your return—whether on paper or through approved electronic options.

We’ll also walk you through each step of the filing process, including gathering documents, calculating your 2016 income tax, applying credits, and understanding where to file. Whether you’re preparing as an individual, part-year resident, or sole proprietor, you’ll find clear, up-to-date instructions to help you confidently prepare your return. Let’s begin by looking at who was required to file a Kansas tax return for the 2016 tax year.

Who Needs to File a Kansas Tax Return for 2016?

If you lived in Kansas during 2016, you may still be required to file a tax return, even if you had little or no taxable income. Kansas filing requirements are based on your residency status, gross income, filing status, and age. Some individuals must also file a tax return to claim a refund, even if they do not owe any taxes.

Kansas residents must file a 2016 tax return if they meet the following criteria:

  • Filed a federal income tax return for 2016:  If you were required to file a federal return, Kansas generally requires you to file a state income tax return as well, even if your Kansas tax liability is zero.

  • Earned more than the state’s filing threshold: You must file if your Kansas adjusted gross income exceeded the combined total of your standard deduction and personal exemption allowance for your filing status and age.

  • Had Kansas taxes withheld and want a refund: If your employer withheld Kansas income tax from your paycheck in 2016, you must file to claim a refund—even if your income was below the threshold.

2016 Income Thresholds by Filing Status and Age

You were required to file a Kansas return in 2016 if your gross income equaled or exceeded the following limits:

  • Single


    • Under age 65: $5,250

    • Age 65 or older: $6,100

    • Age 65 or older and blind: $6,950

  • Married Filing Jointly


    • Both under 65: $12,000

    • One spouse 65 or older or blind: $12,700

    • Both spouses 65 or older or blind: $13,400

    • Both spouses 65 or older and blind: $14,800

  • Head of Household


    • Under age 65: $10,000

    • Age 65 or older or blind: $10,850

    • Age 65 or older and blind: $11,700

  • Married Filing Separately


    • Under age 65: $6,000

    • Age 65 or older or blind: $6,700

    • Age 65 or older and blind: $7,400

Special Situations That May Also Require Filing

You may need to file a Kansas tax return for 2016 even if your income was below the thresholds:

  • Nonresidents and part-year residents must file if they earned income from Kansas sources. You must also complete Schedule S to allocate your income correctly.

  • Dependents who earned more than $5,250 in 2016 may be required to file, even if claimed on another person’s return.

  • Taxpayers who are owed a refund in 2016 must file to receive it. This includes anyone who had Kansas income taxes withheld from their paycheck.

  • Self-employed individuals and sole proprietors must file if they earned Kansas-sourced business income, even if their tax liability is $0.

Filing a late return helps you update your records with the Kansas Department of Revenue and may help you avoid future penalties. The following section will examine how the 2016 tax law changes may impact your return.

Key Changes to Kansas Income Tax for the 2016 Tax Year

Several policy changes impacted how Kansas taxpayers needed to file their 2016 income tax returns. While the basic filing structure remained consistent, updates to exemptions, deductions, and credit eligibility rules affected who should file and how much they might owe or be refunded. Understanding these changes can help you avoid errors, answer common questions, and ensure you pay only what is necessary.

Low-Income Exclusion for 2016

For the 2016 tax year, Kansas implemented an exclusion for low-income taxpayers. If you were single, head of household, with a taxable income of $5,000 or less, or married, filing jointly with $12,500 or less, your state tax liability was zero. However, you were still required to file a return to claim this benefit.

Social Security Number Requirements for Credits

In 2016, Kansas required all individuals claiming tax credits to have a valid Social Security Number for the whole tax year. This rule applies to the primary filer, spouse (if filing jointly), and any dependents listed for credit purposes. Credits affected by this requirement include the earned income credit, food sales tax credit, and credits for taxes paid to other states.

Changes to Itemized Deductions

Kansas adjusted how itemized deductions were calculated on state returns. For 2016:

  • Charitable contributions remained 100% deductible.

  • On the Kansas return, you can only deduct 50% of qualified residential interest and 50% of real and personal property taxes—even if they are fully deductible on the federal return. Adjustments are reported using Schedule S when completing your Kansas return.

Credit Extensions and Pass-Through Exemptions

Kansas extended two key tax credits through 2021: the Angel Investor Credit (Form K-30) and the Rural Opportunity Zone (ROZ) Credit, which must be filed electronically. The state continued to exempt income from pass-through entities like sole proprietorships and partnerships. Even if this income was exempt, filers still needed to report it on their Kansas income tax return.

Tip: If you moved from another state, such as Texas, and earned Kansas income, you may need to file a part-year resident return using Schedule S. If eligible, you can file for free through Kansas WebFile.

These updates highlight the importance of using the proper forms and credit schedules when filing your 2016 return.

Kansas Tax Forms You’ll Need for Your 2016 Income Tax Return

Before you begin the filing process, gathering the correct Kansas tax forms for your situation is essential. Whether you’re filing as an individual, claiming state credits, or reporting business income, using the proper documents will help you avoid delays and ensure your return is complete. All official forms can be downloaded from the Kansas Department of Revenue website.

Forms for Individual Filers

Most individuals will file their 2016 income tax return using Form K-40, the standard Kansas income tax form. If your return includes additions, subtractions, or itemized deductions, you’ll also need Schedule S. To submit a payment, include Form K-40V, the payment voucher.

You can access these forms directly at the Kansas Department of Revenue’s official archive:

Forms for Credits and Special Situations

You must attach the appropriate credit form to qualify for Kansas tax credits. These may include:

  • K-30 for the Angel Investor Credit

  • K-37 for the Disabled Access Credit

  • K-47, K-59, or K-60 for historic preservation, service contributions, or high-performance incentives

A complete list of 2016 credit forms is available through the Kansas tax credits page.

Forms for Business Owners and Self-Employed

Sole proprietors and small business owners will typically still file using Form K-40, but with additional attachments based on entity type:

  • Schedule S (Parts A & B)—Required for income modifications or nonresident income allocation

  • Form K-120 – For partnerships

  • Form K-120S – For S corporations

  • Form K-131 – For composite returns of nonresident partners or shareholders

Using the correct tax forms ensures your return reflects your full financial activity and helps you avoid IRS-related issues. Next, we’ll guide you through completing Form K-40 for 2016.
