Raised Bill No. 7270 introduces significant amendments to Connecticut's tax law, focusing on the procedures for taxpayers to contest tax assessments and the requirements for filing protests. Effective October 1, 2025, taxpayers must submit a detailed form prescribed by the Commissioner of Revenue Services when filing a protest, including their legal name, contact information, tax type, periods at issue, and specific issues contested, along with supporting evidence. If the required information is not provided, the commissioner will notify the taxpayer, who has ten business days to comply; otherwise, the protest will be deemed invalid. The bill also repeals and replaces Section 12-206, updating the penalty structure for late tax payments and granting the commissioner authority to request additional information and make determinations on protests within 180 days.

Additionally, the bill modifies the treatment of certain income and expenses for state tax purposes, including phased deductions for pension and annuity income and IRA distributions based on income levels. It establishes new requirements for filing claims for refunds and amending returns, with specific timeframes for responses from the commissioner. The language throughout the bill has been updated for clarity and gender neutrality, replacing terms like "his" with "the commissioner's." Overall, Raised Bill No. 7270 aims to streamline tax compliance, enhance transparency, and provide tax relief to lower and middle-income individuals while ensuring clearer guidelines for taxpayers and the commissioner.
