Connecticut Cert-106 Vehicle Use Tax Refund Form (Fillable PDF)

The Connecticut Cert-106 is the official claim form used to request a refund of use tax paid on a motor vehicle purchase. Whether you bought a car, truck, or motorcycle and believe you over‑paid tax, this fillable PDF lets you submit a proper request to the Connecticut Department of Revenue Services (DRS) quickly and accurately.

What is the Cert-106 Form?

Cert-106, officially titled “Claim for Refund of Use Tax Paid on Motor Vehicle Purchased,” collects essential details about the buyer, the vehicle, and the tax paid. The DRS reviews the information and, if eligible, issues a refund.

Who Needs to File Cert-106?

• Individuals who purchased a vehicle and paid Connecticut use tax but qualify for a refund (e.g., out‑of‑state purchase, trade‑in adjustments).
• Dealers or businesses that acted as the purchaser on behalf of a client.
• Anyone who can provide proof of tax payment and supporting documentation within three years of the payment date.

Common Mistakes to Avoid

• Missing signatures: The purchaser’s declaration on the back of the form must be signed.
• Incorrect dates: Use the exact date the tax was paid, not the purchase date.
• Incomplete documentation: Attach the original receipt and any trade‑in paperwork; otherwise the claim will be rejected.
• Submitting after three years: The DRS only accepts claims within three years of the tax payment.
