I have paid the first half tax but won be able to pay the second half tax by October 31. What will happen then?
On November 1, interest at 1 percent per month will be charged against the unpaid second half tax amount. In addition to the interest, on December 1, an 8 percent penalty will be charged against the unpaid second half tax amount. (RCW 84.56.020). (External link) Although interest continues to accrue as long as the tax remains delinquent, the penalty is assessed against the current year tax and will not change. These interest and penalty charges apply to both real and personal property.
