Indiana Income Tax Forms – Everything You Need to Know

Paying taxes is one of the many civic responsibilities of every American citizen. If you are a resident of Indiana, you are required by law to file a state income tax return every year. Indiana income tax forms are widely available online and at designated tax preparation sites throughout the state. In this article, we will give you everything you need to know about Indiana income tax forms and how to file your taxes in the state.

Indiana Income Tax Rates

Indiana has a flat state income tax rate of 3.23% for the year 2021. This has remained the same since 2017, when the state legislature passed a bill reducing the tax rate from 3.4% to 3.23%. Indiana is one of only eight states that have a flat income tax rate.

Indiana tax brackets define the income range for each tax rate. For instance, if your taxable income falls between $3,000 and $6,000, you will be taxed at a rate of 2.31%. If your income is above $150,000, you will pay the top rate of 3.23%.

The Indiana Department of Revenue adjusts income tax brackets annually to account for inflation. Taxpayers are encouraged to check the latest Indiana income tax rates before filing their state tax returns.

Indiana Income Tax Forms

The Indiana Department of Revenue releases different types of income tax forms each year based on your income level and filing status. Most people need to file either Form IT-40 or IT-40PNR. IT-40 is for individual taxpayers, while IT-40PNR is for part-year and nonresident taxpayers.

Form IT-40 – Indiana Individual Resident Income Tax Return

If you are an Indiana resident with a gross income of at least $1,000 in the previous year, you must file Form IT-40. This form is free and is available on the Indiana Department of Revenue website. You can also file online using the INtax program.

To complete Form IT-40, you first need to determine your taxable income. This includes your federal adjusted gross income plus or minus certain adjustments, credits, and deductions. Some of these adjustments include itemized deductions, college savings plans, and health savings account contributions.

There are several schedules that you might need to use when filing Form IT-40. For instance, if you have deductions that exceed the standard deduction, you may need to use Schedule 2. If you made donations to charity, you will need to use Schedule 6 to report them.

Form IT-40PNR – Indiana Part-Year and Nonresident Income Tax Return

Form IT-40PNR is for Indiana residents who spent part of the year living outside of Indiana or non-residents who received income from Indiana sources. You might also use this form if you qualify for a reciprocal state exemption.

The form includes the same schedules as Form IT-40 and requires you to determine taxable income based on the percentage of time spent living and working in Indiana. If you are eligible for any credits or exemptions, you will need to include them on the form.

Other Indiana Tax Forms

In addition to Forms IT-40 and IT-40PNR, the Indiana Department of Revenue releases other income tax forms based on different sources of income or deductions. Some of the most common ones include:

– Form IT-40RNR – Indiana Reciprocal Nonresident State Tax Credit
– Form IT-40WH – Indiana Withholding Exemption and County Status Certification
– Form IT-2440 – Indiana Deduction for Health Savings Accounts

You can find a full list of Indiana income tax forms on the Indiana Department of Revenue website.
