Connecticut tax amnesty will run from September 16 through November 15, 2013. For those who may owe money to Connecticut, this is a great opportunity. The amnesty applies to all tax periods ending on or before November 30, 2012. The benefits of the amnesty program are elimination of all penalties, a 75% reduction in interest charges, and avoidance of criminal penalties. To qualify for the amnesty, the entire payment due must be made electronically no later than November 15, 2013. There is absolutely no provision for installment agreements or any type of deferred payment plans. Post-amnesty payments will be charged with interest at 1% per month and a 25% penalty. Unpaid sales and use taxes for purchases qualify for Connecticut's amnesty.
