The July 2016 tax bills are being mailed the last week of June and have a July 15th due date. If your bill is more than $100.00, you will have the option of paying in quarterly installments due this year on July 15, October 1, January 1 and April 1. There is a six (6) business day grace period on each installment. However, RIGL 44-5-8 is very clear that if any installment is late, then the whole tax (or remaining unpaid balance) becomes due and payable (including interest and penalties). It should also be noted that RIGL 44-7-7 states that failure by the taxpayer to receive a bill shall not excuse the nonpayment of the tax.
