Connecticut Sales Tax Enforcement Actions Checklist
Introduction
Sales tax enforcement actions are formal notices issued by the Connecticut Department of
Revenue Services when a business may have unpaid sales tax, missing sales tax returns, or unresolved tax filings under Connecticut laws. These actions signal that the state has identified a potential tax liability tied to sales tax collection, economic nexus, or failure to comply with sales and use tax requirements.
Enforcement actions follow a structured administrative process that allows taxpayers to review the claim, submit records, or resolve balances before tax collection escalates. Responding promptly helps avoid penalties, liens, and disruptions to ongoing business activities.
What This Issue Means
A sales tax enforcement action means the Department of Revenue Services has moved beyond routine reminders and is actively addressing a perceived compliance issue. This may involve a proposed assessment, an audit process notice, a demand for payment, or a notice related to missing tax returns.
The notice reflects the state’s position based on available sales records, tax filings, or nexus thresholds tied to physical presence or the presence of out-of-state sellers. The specific enforcement document outlines the required action and identifies the periods under review.
Why the State Issued This or Requires This
Connecticut issues sales tax enforcement actions when administrative systems detect unpaid balances, zero-dollar filings, missing returns, or inconsistencies during an audit process.
Enforcement may also arise when businesses exceed economic nexus thresholds or conduct marketplace transactions without proper registration.
The state relies on these actions to enforce sales tax laws, close the tax gap, and ensure accurate remittance of sales and use taxes. Notices are designed to prompt resolution before stronger collection measures are initiated.
What Happens If This Is Ignored
Failing to address a sales tax enforcement action allows the Department of Revenue Services to escalate tax collection efforts under Connecticut law. The state may assess additional tax penalties, apply interest, or issue jeopardy assessments based on available data.
Continued nonresponse can result in liens, levies, permit suspension, or referral to the
Collection & Enforcement Division. In severe cases involving suspected tax fraud or willful noncompliance, matters may be referred for criminal investigation through federal or state task forces.
What This Does Not Mean
Receiving an enforcement notice does not automatically mean criminal tax cases are pending or that search and seizure warrants have been issued. Most enforcement actions are civil and administrative, not criminal investigations involving the Department of Justice.
It also does not mean the tax determination is final. Taxpayers generally retain the right to protest, appeal, and submit documentation before the assessment becomes enforceable.
Checklist: What to Do After Receiving a Sales Tax
Enforcement Action
Step 1: Review the Enforcement Notice Carefully
Confirm the sales tax periods involved, response deadlines, and the stated reason for enforcement. Identify whether the issue involves sales tax nexus, unpaid tax returns, or unfiled sales tax returns.
Step 2: Confirm Registration and Permit Status
Verify the sales and use tax permit, seller’s permit, and registered agent information with the
Connecticut Department of Revenue Services. Confirm that business formation records align with current operations.
Step 3: Gather Sales and Filing Records
Assemble sales records, sales tax returns, resale certificates, and documentation supporting taxable services or digital goods. Ensure records reconcile with reported sales tax rates and marketplace facilitator activity.
Step 4: Verify Nexus Exposure
Review physical presence, economic nexus thresholds, and marketplace transactions, including
Amazon Fulfillment by Amazon or drop-shipping arrangements. Confirm compliance for out-of-state sellers operating in Connecticut.
Step 5: Review the Amount Claimed
Compare the state’s calculation to internal records, including tax filings and payment confirmations. Identify discrepancies tied to shipping charges, software delivered electronically, or taxable services.
Step 6: Determine Response Strategy
Decide whether to dispute the assessment, request a penalty waiver, or resolve the balance through payment. Consider Voluntary Disclosure Agreements if prior periods were not reported.
Step 7: Contact the Assigned DRS Representative
Please reach out using the provided contact information to clarify any questions you may have about the audit process or tax collection steps. Document all communications and reference numbers.
Step 8: Submit Documentation or Protest on Time
Provide organized records supporting your position, including sales records and resale certificates. Ensure submissions comply with procedural requirements under Connecticut law.
Step 9: Address Payment Options If Liability Is Due
If payment is required, ask about installment arrangements and interest calculations. Confirm terms in writing before remitting funds.
- 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 10: Maintain Ongoing Compliance
Continue timely sales tax filings and payments during enforcement to reduce audit risk. New delinquencies may expand the scope of review.
What Happens After This Is Completed
After submission, the Department of Revenue Services reviews records, evaluates compliance with sales tax laws, and issues a Tax Determination Report if adjustments are required.
Additional documentation may be requested before finalizing the assessment.
If tax liability is confirmed, the state issues a notice outlining amounts due, appeal rights, and payment timelines. If overpayment is identified, credits may be applied subject to statutory limits.
Common Mistakes to Avoid
Missing response deadlines often result in estimated assessments that rely on public data rather than actual sales records. Disorganized files, incomplete resale certificates, and inconsistent totals often result in avoidable adjustments.
Another frequent mistake involves treating enforcement notices like routine tax preparation intake rather than legal documentation under state tax law. Mixing unrelated taxes, such as payroll tax or property tax, with sales and use taxes can delay resolution.
