State Tax Appeal
Connecticut State Tax Appeal
Drafting aid for a protest to the Department of Revenue Services Appellate Division and a tax-specific appeal to the Superior Court
IMPORTANT — IDENTIFY THE TAX-SPECIFIC ROUTE
Connecticut does not use a generic statewide “Tax Tribunal” petition for the DRS matters covered here. The ordinary sequence is a written protest to the Commissioner of Revenue Services, followed by a tax-specific appeal to the Superior Court for the Judicial District of New Britain after the Commissioner issues the appealable determination.
| Tax track | Administrative authority | Court authority | Ordinary deadline stated by current authority |
|---|---|---|---|
| Corporation business tax | Conn. Gen. Stat. § 12-236 | Conn. Gen. Stat. § 12-237 | Written hearing request within 60 days after the notice is delivered or mailed; court appeal no later than 30 days after service of the Commissioner's notice |
| Sales and use tax | Conn. Gen. Stat. § 12-421 | Conn. Gen. Stat. § 12-422 | Written hearing request within 60 days after the notice is delivered or mailed; court appeal no later than 30 days after service of the Commissioner's notice |
| Income tax deficiency | Conn. Gen. Stat. § 12-729 | Conn. Gen. Stat. § 12-730 | Written protest within 60 days after mailing of the deficiency notice; court appeal no later than 30 days after mailing of the Commissioner's determination or disallowance |
DRS's current protest guidance states that a protest of a notice of assessment, proposed refund disallowance, or other determination generally must be received or bear a United States postmark within 60 days after the date of the notice. A protest of a jeopardy assessment must be received or bear a United States postmark within 10 days after the date of the notice. Use the shorter deadline shown on the notice when applicable.
Municipal property tax is separate
This template is not a municipal real-estate, personal-property, or motor-vehicle tax appeal. The Connecticut Judicial Branch identifies municipal property-tax routes under Conn. Gen. Stat. §§ 12-117a and 12-119 and directs those appeals initially to the judicial district where the municipality is located. Do not use the New Britain DRS caption below for a municipal appeal without confirming the governing statute and venue.
Payment, interest, and cash-bond warning
- DRS states that interest continues to accrue on unpaid assessed tax while an administrative protest is considered.
- Conn. Gen. Stat. § 12-39m permits—but does not require—a taxpayer to make a written-designated deposit in the nature of a cash bond to limit interest on the portion treated as deposited without conceding liability.
- DRS Form APL-004 is the designated cash-bond form. Filing APL-004 is not itself a protest.
- Do not insert a fictional automatic collection stay or mandatory “10% deposit.” The bond or recognizance required with a court citation under §§ 12-237, 12-422, and 12-730 is a bond or recognizance to prosecute the appeal and comply with court orders, not the former template's invented 10% assessment deposit.

About This Template
Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.
