Key Answer: Individual Filing Deadlines
If you want a direct answer to the basic question about individual taxes: Indiana individual income tax returns are generally due on the same date as the federal return, usually in mid-April, and estimated quarterly payments are due four times each year. This alignment makes it simpler to keep state and federal timing consistent.

How Extensions Work and What They Cover
Extensions let you file your paperwork later, but they don’t always extend the time to pay. In Indiana, filing an extension typically mirrors federal rules. Next, know that you still owe any tax due by the original due date to avoid interest.
- Extensions usually require you to file Form IT-9 or follow federal extension procedures.
- They give extra time to file, not to pay.
- Paying what you estimate avoids interest and penalties.
Additionally, you should estimate what you owe before the original due date. If you underpay, interest and late-payment penalties start accruing from the original due date until you pay in full.
Finally, remember that electronic filing and the state’s resources can simplify the extension process and show you how to report estimated payments.

Estimated Payments: Who Pays and When
Many taxpayers must make estimated payments if they expect to owe tax beyond what is withheld from paychecks. For example, self-employed people, landlords, and investors often pay quarterly to avoid a large bill at year end.
Below is a small table summarizing common estimated payment periods and what they cover.
| Quarter | Typical Coverage |
|---|---|
| 1st Quarter | Income Jan–Mar |
| 2nd Quarter | Income Apr–Jun |
| 3rd Quarter | Income Jul–Sep |
| 4th Quarter | Income Oct–Dec |
Moreover, Indiana generally follows the federal schedule for estimated payments. If you make overpayments, you can apply them to future taxes or request a refund when you file your return.
Penalties and Interest for Late Filing or Late Payment
Filing or paying late can trigger two costs: penalties and interest. The state charges interest on unpaid balances and may add late-filing or late-payment penalties, which grow over time.
To reduce risk, know common penalty triggers and act quickly if you miss a deadline.
- Failing to file by the due date
- Failing to pay the tax due
- Underpaying estimated taxes
Moreover, if you can’t pay the full amount, contact the Indiana Department of Revenue to discuss payment plans or installment agreements before penalties grow larger.
Deadlines for Partnerships and S Corporations
Business entities follow different schedules. Partnerships and S corporations have return deadlines that usually fall earlier than individual returns, so owners and managers must coordinate to gather K-1s and other data.
First, these entities file informational returns that pass income to owners. Owners then report that income on their individual returns. Missing an entity deadline can cascade into owner deadlines.
Second, many owners face tight timelines because pass-through entity returns must be prepared before owners can file. Consider using a tax professional or calendar reminders to stay on schedule.
Finally, if a partnership or S corp needs more time, they can request an extension, but remember that any tax owed by owners or the entity still faces deadlines for payment and potential interest.
Corporate Income Tax Deadlines
Corporations have distinct deadlines and payment rules compared to individuals and pass-through entities. Corporations often pay estimated tax and file on a different schedule depending on their fiscal year.
Companies should track estimated corporate payments and annual filings carefully to avoid underpayment penalties. Below are common items corporations monitor.
- Quarterly estimated corporate tax payments
- Annual corporate tax return tied to fiscal year end
- State-specific filing forms for Indiana corporations
Moreover, corporations may face different penalty structures, so it’s wise to consult a CPA to confirm exact dates tied to a company’s fiscal year and to confirm the current corporate tax rate.
Sales Tax and Withholding: Frequency and Filing
Sales tax and employer withholding are collected on a regular schedule and remitted to the state. The frequency (monthly, quarterly, or annually) depends on the amount of tax collected or withheld.
Here’s a quick ordered list showing typical filing frequency options based on volume and type.
- Monthly: high-volume collectors
- Quarterly: medium-volume businesses
- Annually: very small-volume filers
Additionally, register your business for the correct schedule when you begin operations, and update the state if your collection volume changes so you don’t miss more frequent filing requirements.
In short, staying on top of Indiana tax due dates means matching your filings to the right category—individuals, pass-throughs, corporations, or businesses collecting sales or withholding. Use calendar reminders, make estimated payments on time, and contact the Department of Revenue or a tax professional if you need help. Take action today: review your filing calendar and set automated reminders so you never miss a key date.
