Indiana Unfiled Sales Tax Returns Checklist
Introduction
An unfiled sales tax return occurs when a retail merchant in the State of Indiana does not submit a required sales tax return to the Indiana Department of Revenue for one or more reporting periods. Sales tax is collected from customers and held in trust for the state, which makes timely filing and remitting a legal obligation rather than an optional task.
When sales tax returns remain unfiled, the state typically detects the gap through registration records, reported sales activity, or third-party data. Addressing unfiled returns early helps limit tax liabilities, reduce interest and penalties, and prevent escalation into tax liens, a tax warrant, or other enforcement actions.
What This Issue Means
An unfiled sales tax return means the Indiana Department of Revenue has no record of a required filing for a specific reporting period. Without a filed return, the state cannot determine whether sales tax was collected, remitted, or still owed, creating a compliance gap under state tax law.
Filing frequency is determined by sales volume and average tax liability. Some businesses file monthly, while others file annually. Missing even one required return places the account in an unfiled returns status until corrected.
Why The State Issued This Or Requires This
Indiana requires sales tax returns to track and verify state taxes collected from consumers.
Filing allows the Indiana Department of Revenue to confirm that retail merchants properly remitted sales tax at the statewide rate and complied with registration requirements.
Unfiled returns often result from missed deadlines, business transitions, administrative oversight, or misunderstanding of filing obligations. When the state identifies a registered retail merchant with missing tax returns, it issues notices or initiates collection activity to enforce compliance.
What Happens If This Is Ignored
If unfiled sales tax returns are ignored, the Indiana Department of Revenue may assess estimated tax liabilities using available data. These estimates are often higher than actual sales tax owed and include penalties, interest, and collection fees.
Continued noncompliance can lead to collection actions such as bank levies, wage garnishment, or the filing of a tax warrant. A tax warrant becomes a public record and may result in a tax lien that affects property, licensing, and future business activity.
What This Does Not Mean
An unfiled return notice does not mean the business is shut down, charged with tax evasion, or subject to criminal prosecution. It also does not automatically imply assets have been seized or that a court judgment has been entered.
The notice does not reflect a final determination of tax debt. The actual amount owed is typically established only after the sales tax returns are filed or the state completes a review.
Checklist: What To Do After Receiving This Or Identifying
This Issue
Step 1: Locate the sales tax registration details
Locate the Retail Merchant Certificate or registration records issued by the Indiana Department of Revenue. The registration number is required to access the account and file missing sales tax returns.
Step 2: Identify all unfiled reporting periods
Review notices, account statements, or correspondence to identify which months or years are unfiled. Each period must be addressed individually to restore compliance.
Step 3: Gather sales and transaction records
Collect records showing gross sales, taxable sales, refunds, and exemptions for each unfiled period. Documentation may include point-of-sale reports, invoices, and bank deposits.
Step 4: Calculate taxable sales and sales tax due
Determine taxable sales for each period and apply Indiana’s uniform sales tax rate. Indiana does not impose local sales tax rates, so the statewide rate applies to all taxable transactions.
Step 5: Contact the Indiana Department of Revenue
Call the Indiana Department of Revenue using the contact information on the notice. Confirm filing requirements, accepted filing methods, and whether the state expects paper forms or electronic submission.
Step 6: Request filing instructions for past periods
Ask whether unfiled tax returns can be submitted through the online system or must be mailed.
Confirm mailing addresses, filing deadlines, and documentation requirements.
Step 7: Complete the unfiled sales tax returns
Prepare each sales tax return using accurate sales data for the period involved. Review totals carefully to ensure reported figures align with business records.
Step 8: Submit the completed returns
File the returns using the approved method and retain proof of submission. Confirmation records help prevent disputes over whether returns were received.
Step 9: Address any tax debt identified
If tax debt exists after filing, contact the Indiana Department of Revenue to discuss payment options. Installment agreements may be available if full payment is not immediately possible.
Step 10: Keep detailed records of all actions
Save copies of filed tax returns, payment confirmations, and correspondence. Organized records help resolve future questions and demonstrate compliance.
Step 11: Monitor for follow-up communication
Watch for notices confirming processing, assessing penalties, or requesting clarification.
Respond promptly to prevent further enforcement.
- State enforcement notices and responses
- Sales tax audits, assessments, and collections
- Payroll & trust fund tax enforcement issues
- Penalty and interest reduction options
- Payment plans and state tax relief eligibility
- Representation before state tax agencies
Step 12: Maintain ongoing filing compliance
Ensure future sales tax returns are filed by the assigned filing deadline. Consistent compliance prevents repeat enforcement and additional tax problems.
What Happens After This Is Completed
Once unfiled sales tax returns are submitted, the Indiana Department of Revenue processes the filings and updates the account. The state may compare reported figures to existing data and request clarification if discrepancies appear.
If returns are accepted, penalties and interest may still apply depending on how long the returns were unfiled. Payments are applied to the outstanding balance, and compliance status is restored once obligations are satisfied.
Common Mistakes To Avoid
Failing to respond to notices often leads to estimated assessments and higher tax liabilities.
Another standard error is filing incomplete or inaccurate returns, which delays resolution and increases penalties.
Some businesses assume the state will calculate the correct amount owed, but estimates are often unfavorable. Missing future filing deadlines after resolving past issues can restart enforcement activity.
