Effective October 1, 2014, the deadline for remitting monthly Connecticut sales and use taxes and filing returns is changed to on or before the 20th day of the month next succeeding each monthly period. Prior to October 1, 2014, the deadline is the last day of the month. The Connecticut Department of Revenue Services may require any person who is delinquent to remit the tax collected during a weekly period on a weekly basis. Anyone who is required to remit tax for a weekly period is required to remit the tax on or before the Wednesday next succeeding the weekly period. The requirement to remit tax on a weekly basis does not change a person’s obligation to file monthly or quarterly returns. The Department is required to send a written notice informing anyone required to remit tax on a weekly basis. Anyone so required must remit tax on a weekly basis for one year beginning on the date indicated in the written notice. Any person who fails to remit tax on a weekly basis is subject to all penalties imposed under the sales and use tax laws, including the revocation of that person’s permit. (Act 155 (H.B. 5466), Laws 2014, effective as noted)
