Connecticut § 12-728

• Jurisdiction: Connecticut
• Title 12: Taxation
• Ch. 229: Income Tax

Text

(a)(1) After a final return pursuant to the provisions of this chapter is filed, the commissioner shall cause the same to be examined and may make such further audit or investigation or reaudit as the commissioner deems necessary, and if the commissioner determines that there is a deficiency with respect to the payment of any tax due under this chapter, the commissioner shall assess or reassess the additional taxes, penalties and interest due to this state, give notice of such assessment or reassessment to the taxpayer and make demand upon the taxpayer for payment. Not later than sixty days after the mailing of such notice, the taxpayer shall pay to the commissioner, in cash or by check, draft or money order drawn to the order of the commissioner, the amount of the deficiency. Such amount shall bear interest at the rate of one per cent per month or fraction thereof from the date when the original tax became due and payable. (2) (A) When it appears that any part of the deficiency for which a deficiency assessment is made is due to negligence or intentional disregard of the provisions of this chapter or regulations adopted thereunder, there shall be imposed a penalty equal to ten per cent of the amount of such deficiency assessment. When it appears that any part of the deficiency for which a deficiency assessment is made is due to fraud or intent to evade the provisions of this chapter or regulations adopted thereunder, there shall be imposed a penalty equal to twentyfive per cent of the amount of such deficiency assessment. (B) (i) For audits of returns commencing on or after January 1, 2006, and prior to January 1, 2018, when it appears that any part of the deficiency for which a deficiency assessment is made is due to failure to disclose a listed transaction, as defined in Section 6707A of the Internal Revenue Code of 1986, or any subsequent corresponding internal revenue code of the United States, as amended from time to time, on the taxpayer's federal tax return, there shall be imposed a penalty equal to seventy-five per cent of the amount of such deficiency assessment. (ii) For audits of returns commencing on or after January 1, 2018, when it appears that any part of the deficiency for which a deficiency assessment is made is due to failure to disclose a reportable transaction, as defined in said Section 6707A, on the taxpayer's federal tax return, there shall be imposed a penalty equal to seventy-five per cent of the amount of such deficiency assessment. (3) No taxpayer shall be subject to more than one penalty under this section in relation to the same tax period. (4) Any decision rendered by any federal court holding that a taxpayer has filed a fraudulent return with the Director of Internal Revenue shall subject the taxpayer to the twenty-five per cent penalty imposed by this subsection without the necessity of further proof thereof, except when it can be shown that the return to the state so differed from the return to the federal government as to afford a reasonable presumption that the attempt to defraud did not extend to the state. (b) A notice of deficiency shall set forth the reason for the proposed assessment. The notice shall be mailed to the taxpayer at his last-known address. In the case of a joint return, the notice of deficiency may be a single joint notice except that if the commissioner is notified by either spouse that separate residences have been established he shall mail joint notices to each spouse. If the taxpayer is deceased or under a legal disability, a notice of deficiency may be mailed to his last-known address unless the commissioner has received notice of the existence of a fiduciary relationship with respect to such taxpayer. See Sec. 12-30c re penalty on promoter of abusive tax shelters.
