Quarterly Estimated Taxes for Indiana LLCs
If your Indiana LLC generates income resulting in $1,000+ owed in Indiana state taxes or federal taxes, you must make quarterly estimated payments. Indiana uses Form ES-40 filed through INTIME. For the full tax picture, see our Indiana LLC tax guide. For formation, see how to form an Indiana LLC.
Due Dates
| Quarter | Period | Due Date |
|---|---|---|
| Q1 | Jan-Mar | April 15 |
| Q2 | Apr-May | June 15 |
| Q3 | Jun-Aug | September 15 |
| Q4 | Sep-Dec | January 15 (next year) |
These dates apply to both Indiana state estimates (Form ES-40) and federal estimates.
How to Calculate Indiana Estimates
- Estimate annual Indiana taxable income from LLC
- Apply 2.95% state rate + your county rate
- Subtract any withholding (if you also have a W-2 job)
- Divide remaining tax by 4
Safe harbor: Pay 100% of prior year's Indiana tax liability divided by 4 to avoid underpayment penalties (110% if AGI exceeded $150,000).

County Tax in Estimates
Your quarterly estimates must include BOTH state (2.95%) and county income tax. The combined amount goes on Form ES-40 — Indiana doesn't separate state and county payments.
Example (Marion County resident, LLC nets $100,000):
- State tax: $100,000 × 2.95% = $3,050
- County tax: $100,000 × 2.02% = $2,020
- Total Indiana tax: $5,070
- Quarterly payment: $5,070 ÷ 4 = $1,268
FAQ
Does Indiana penalize underpayment?
Yes. Indiana charges a penalty on quarterly underpayments calculated on Form IT-2210. The rate is the federal short-term rate + 3%.
Do I make separate county and state payments?
No. One combined payment covers both state and county income tax.
When do estimates start for a new LLC?
First payment is due for the quarter in which you first generate income.
