Indiana · Tax Notices

Got an Indiana tax notice? Read it right, then act.

What the notice is — and which agency sent it — matters more than the title, and the deadline near the top matters most of all. TechBrot is a bookkeeping and advisory firm working with Indiana businesses statewide; we help you tell a simple information request from a real assessment and reconcile the books to find out whether you actually owe what the state claims, then hand your CPA, EA, or tax attorney clean figures and documentation to respond with. We provide operational support and documentation only — we do not respond to notices on your behalf and we do not represent you before the Indiana Department of Revenue or the county assessor.

TechBrot is a bookkeeping and advisory firm — not the Indiana Department of Revenue, not the county assessor or DLGF, not any government agency, and not a CPA, EA, or tax attorney. Contacting us does not reach the state. We provide operational support and documentation only: we do not respond to notices on your behalf, do not represent you before any agency, do not provide tax or legal advice, and do not file returns, protests, or the business personal-property return.

We help you understand the notice, reconcile the underlying books, and assemble clean figures and documentation your licensed professional uses to respond. This page is educational; it is not legal or tax advice.

§ 01 · The short version
§ The short version

Indiana tax notice help means reconciling the books behind the notice: TechBrot pins down the agency, type and deadline, rebuilds the period and gives your licensed professional documented figures. Deadlines are short: a demand for payment allows only 20 days, and an estimated bill for a missing return can be protested within 60 days.

§ 02 · Know what you’re holding

Common Indiana business tax notices.

The issuing agency and the type are usually printed at the top. Match it here before you do anything else — the right response depends entirely on which notice this is. Identifying the type and deadline is where we start; your CPA, EA, or tax attorney responds.

Indiana DOR · Bill

A bill for tax due.

The Department of Revenue says tax is due — sales/use, withholding, county LIT, or corporate income — and is demanding payment. Interest and penalties accrue; left unpaid, it heads toward a tax warrant and lien. The books question: is the amount real, or does it reflect a return that didn’t reconcile?

Indiana DOR · Proposed Assessment

Proposed assessment with protest rights.

A proposed assessment carrying formal protest rights. The protest must be filed in writing by the deadline on the notice or it becomes final — that filing is your CPA or tax attorney’s to make, on reconciled figures.

Indiana DOR · Sales / Use Tax

Sales-tax filing mismatch.

The 7% sales tax the state expected doesn’t match what was filed or paid — common when QuickBooks isn’t configured to track and remit Indiana’s flat sales tax correctly. A reconciled sales-tax workpaper often changes the number in question.

Indiana DOR · Withholding / County LIT

Withholding or county LIT mismatch.

Withholding reported doesn’t tie to payroll, or county local income tax for the wrong county of residence was withheld (Form WH-4 drives this). Because withholding is trust-fund money, these escalate faster — reconciling payroll to the filings is the fix, and it starts in the books.

Indiana DOR · Request for Information

Request for documents.

The state wants documents to finish processing a return. Respond by the date noted to avoid an adjustment. Often the fastest to clear once the period’s records are organized and reconciled.

County Assessor · Personal Property

Business personal-property (Form 103/104).

The county assessor flags a missing or questioned business personal-property return. For 2026 the exemption threshold rose to $2,000,000, but it is claimed on Form 103 with Form 104. We track the asset detail and prepare the figures; your CPA or assessor-side preparer files.

Indiana sales/use, withholding, county LIT, and corporate-income returns and payments are filed through the Indiana Department of Revenue; the business personal-property return (Form 103 with Form 104) is filed with the county assessor under DLGF rules. A return that wasn’t accepted or didn’t reconcile is a frequent trigger behind these notices. Always confirm the current process and deadlines against the issuing agency.

§ 03 · The most common root cause

Why so many Indiana notices are really books problems

When a return is filed from books that aren’t reconciled, the numbers drift from reality. The state’s systems cross-check what you reported against what it expects — and when those don’t line up, a notice goes out. Typical triggers are sales-tax filings that don’t reconcile to the general ledger (often because the 7% wasn’t configured or tracked correctly in QuickBooks), a return the state never received, withholding or county LIT that doesn’t tie to payroll, and a business personal-property return (Form 103/104) that was never filed.

The practical implication: before you assume a notice is correct and pay it — or assume it’s wrong and ignore it — get the period reconciled. Knowing your true number is what lets your CPA, EA, or tax attorney respond from a position of fact rather than fear. Reconciling that period and preparing the documentation is exactly the work we do.

When a return is missing, the Department can send an estimated bill for it, and you have 60 days from the date the letter was issued to protest in writing (Indiana DOR: understanding your proposed assessment). A demand for payment allows only 20 days to respond; after that, a tax warrant can follow, which becomes a lien on property across the state (Indiana DOR: stages of collection). A business payment plan generally needs more than $500 due, with terms of up to 12, 24 or 36 months by balance (Indiana DOR: payment plans). Your CPA, EA, or tax attorney files the protest or requests the plan; reconciled books are what they file from.

Records example: for a sales-tax bill, the Sales Tax Payable account and the QuickBooks Sales Tax Liability report for each billed period, reconciled to deposits and the ST-103 vouchers; for withholding and county LIT, the payroll tax liability report by period tied to each WH-1 and the year’s WH-3; for personal property, a fixed-asset register with acquisition cost by county. The package is designed for CPA review; acceptance depends on the recipient’s requirements.

Trust-fund tax. Indiana sales tax and payroll withholding are money you collected on the state’s behalf: the Department’s business registration checklist warns that partners or corporate officers are each personally, jointly and severally liable for the sales and use tax collected and the withholding tax withheld, and calls these trust fund taxes that are not discharged in bankruptcy (Indiana DOR, Form BT-1 checklist). That’s why a sales-tax or withholding notice is more urgent than it may look, and why getting the books reconciled quickly matters.

§ 05 · Questions

Indiana tax notice questions.

What does it mean if I got a notice from the Indiana Department of Revenue?

It depends entirely on the notice type — and the type matters more than the title. Some notices simply ask for documents to finish processing a return. Others assert that you owe money and start a clock on your right to protest (a proposed assessment). The first step is always to identify the issuing agency, the notice type, and the deadline printed near the top, then respond before it passes.

How long do I have to respond to an Indiana tax notice?

A response deadline is printed near the top of the notice, and it varies by type. For a proposed assessment you must file your protest in writing by that date to preserve your appeal rights. Confirm the exact date on your own notice against the Indiana Department of Revenue — missing the deadline doesn’t make the issue go away; it removes your options and lets the assessment become final.

What happens if I ignore an Indiana State tax notice?

It escalates. A demand for payment allows only 20 days to respond; after that the Department can collect through a sheriff warrant or its collection agency, and a tax warrant becomes a lien on your property across the state (Indiana DOR: stages of collection). Sales-tax and withholding notices are the most urgent because those are trust fund taxes. Acting on the first notice is always cheaper than reacting to a tax warrant.

Can the issue be from a bookkeeping error rather than real tax owed?

Very often, yes. A large share of Indiana notices trace back to a mismatch — sales tax that doesn’t reconcile to the books (often because the 7% wasn’t configured correctly in QuickBooks), a return the state didn’t receive, withholding or county LIT that doesn’t tie to payroll, or a Form 103/104 that was never filed. When the underlying books are clean and reconciled, many notices are resolved by simply showing the correct figures. That reconciliation is exactly what we do — your CPA, EA, or tax attorney then files the response that resolves the notice.

How does TechBrot help with an Indiana tax notice?

We work the bookkeeping side: reconciling the period in question, identifying whether the notice reflects a real liability or a books/reporting mismatch, and assembling clean, documented figures your CPA or tax attorney can use to respond. We provide operational support and documentation only — we don’t represent you before the state or file the protest or the business personal-property return — we make sure the numbers behind the response are correct and defensible.

Should I call a CPA, a tax attorney, or my county assessor for an Indiana notice?

It depends on the notice. For a straightforward information request or adjustment, your CPA (with clean books behind them) is usually enough. For a proposed assessment, an audit, or anything with protest rights and real money at stake, a CPA or tax attorney should lead the response. A business personal-property (Form 103/104) matter is handled with the county assessor, typically through your CPA or assessor-side preparer. In all cases, reconciled books make their work faster and your position stronger — and that’s where we come in.

I’m behind on Indiana taxes — what are my options?

An estimated bill for a missing return can be protested in writing within 60 days of the date the letter was issued; a business payment plan with the Department of Revenue generally needs more than $500 due, with terms of up to 12, 24 or 36 months depending on the balance; and an unfiled sales-tax, withholding or personal-property return can be cured by filing it. Each is requested and filed by your CPA, EA, or tax attorney, and each needs accurate numbers, which starts with reconciled books. We rebuild and reconcile those books; the path itself is theirs.

Can I be personally liable for my business’s Indiana taxes?

It depends on the tax and your role, and your CPA or tax attorney is the person to ask. The Department’s business registration checklist (Form BT-1) warns that partners or corporate officers are each personally, jointly and severally liable for the sales and use tax collected and the withholding tax withheld, and that these trust fund taxes are not discharged in bankruptcy. Clean records showing what was collected or withheld, and what was remitted, matter a great deal here.
