Indiana Back Taxes Payment Plan: How to Set One Up (2025)

The short answer: if you owe Indiana back taxes, you can set up an Indiana back taxes payment plan online through the Indiana Department of Revenue (DOR) portal called INTIME, or by phone after you get a bill. Most individual plans spread the balance — plus penalty and interest — over monthly payments. Acting before DOR issues a tax warrant keeps your options open.

⏱ Your deadline: once DOR sends a Demand for Payment (the notice after your first bill), you generally have a short window — often about 20 days — to pay or set up a payment plan before a tax warrant is issued. A warrant adds collection fees and opens the door to wage garnishment and bank levies, so move before that date on the notice.

Why you owe Indiana back taxes

Indiana state income tax is separate from your federal IRS bill, and it's easy to fall behind on. The most common reasons people owe Indiana back taxes: you filed an Indiana return but couldn't pay the full balance, you under-withheld during the year, you had self-employment or gig income with no Indiana tax taken out, or DOR adjusted a return and added a balance. County income tax (collected with your state return) can also push the total higher than you expected.

When the balance goes unpaid, Indiana typically adds a penalty — commonly 10% of the unpaid tax — plus interest that accrues until the debt is paid. You can see your balance and notices by logging into your account at the Indiana DOR INTIME portal.

What happens if you ignore an Indiana tax bill

Like the IRS, the Indiana Department of Revenue runs an automated collection sequence. Each step has more teeth than the last:

  1. Notice of Proposed Assessment / billing notice — DOR tells you the amount due and how it breaks down. No enforcement yet.
  2. Demand for Payment — your last clear warning. Pay or set up a plan within the window on the notice (often about 20 days) to avoid a warrant.
  3. Tax warrant — filed in your county, it becomes a judgment lien against you. This can show up on your credit and public records and adds collection fees.
  4. Sheriff or collection agency — the warrant may be turned over to a county sheriff or a private collection partner, which can pursue wage garnishment and bank levies, and can intercept your state tax refund.

The Indiana DOR can also offset your federal and state refunds and certify certain debts for collection. None of this happens overnight — but once a tax warrant is filed, fixing it is more expensive and harder than setting up a plan today.

How an Indiana DOR payment plan works

A payment plan (DOR calls it a payment plan or installment arrangement) lets you pay your Indiana back taxes in monthly amounts instead of all at once. Key things to know:

For full details and to start, use the official Indiana Department of Revenue payments and billing page.

A simple worked example

Say you owe Indiana $3,000 in back taxes. DOR adds a one-time 10% penalty ($300), and interest accrues on the unpaid amount. If DOR puts you on a 12-month plan, you might pay roughly $280–$300 per month — covering the tax, the penalty, and the running interest. Pay it off in 6 months instead and you stop interest sooner and pay less overall. The exact numbers depend on the current interest rate and your approved term, but the lesson is the same: the faster you pay, the cheaper it is.

If you can't afford the monthly payment

Don't let "I can't pay anything" turn into doing nothing. Indiana has more than one path:

If you owe the IRS and Indiana, handle them together. Federal options like a streamlined installment agreement work alongside a state plan, and you can set up an IRS payment plan online separately. The goal is a combined monthly total you can actually live with.

How to set up your Indiana payment plan, step by step

  1. Confirm what you owe. Log into INTIME and check the balance, tax years, and any penalties or interest.
  2. File any missing Indiana returns first. DOR usually won't finalize a plan while returns are unfiled, and unfiled years can lead to estimated bills that are higher than your real liability.
  3. Decide what you can pay monthly — be realistic, because a defaulted plan restarts collection.
  4. Request the plan through INTIME or by calling DOR, before any Demand for Payment deadline passes.
  5. Set up automatic payments if you can so you never miss one, and keep filing and paying future returns on time.
  6. If you owe a lot, have multiple unfiled years, or also owe the IRS, get a professional review first — the order you fix things in changes what you end up paying.

Indiana back taxes questions, answered

How do I set up a payment plan for Indiana back taxes?

The fastest way is online through the Indiana Department of Revenue's INTIME portal at intime.dor.in.gov. You can also call DOR or set a plan up by phone after you receive a bill. Most individual plans require a monthly payment until the balance, plus penalty and interest, is paid off.

What happens if I don't pay my Indiana state taxes?

After a billing notice and a Demand for Payment, the Indiana Department of Revenue can issue a tax warrant. A tax warrant becomes a judgment lien against you in that county and can be turned over to a county sheriff or a private collection agency, which adds fees and can lead to wage garnishment or bank levies.

Can Indiana garnish my wages for back taxes?

Yes. Once the Indiana Department of Revenue has a tax warrant on file, it can pursue wage garnishment, bank levies, and other collection through the county sheriff or its collection partner. Setting up a payment plan before that point is the simplest way to avoid garnishment.

Does Indiana have an offer in compromise like the IRS?

Yes. The Indiana Department of Revenue can accept an Offer in Compromise to settle a tax debt for less than the full amount when you genuinely can't pay it, but approval depends on your income, assets, and circumstances. A payment plan is far more common and easier to get than a settlement.

Do I owe Indiana and the IRS separately?

Often yes. Indiana state tax debt and federal IRS debt are handled by two different agencies with separate notices, deadlines, and payment plans. Paying one does nothing for the other. If you owe both, you usually need a plan with each — and they should be coordinated so the monthly total is something you can actually afford.
