How often are real estate and personal property tax bills mailed?

While the taxes are due four times per year, there are three mailings. The preliminary bills, due August and November, are combined on one mailing. That bill is mailed by the end of June. Once the tax rate has been set by the Assessing Department, the actual bill for the third quarter, due February 1st, is mailed by the end of December. The fourth actual bill, due May 1st, is mailed by the end of March.
