Tax Information

Taxes are mailed out every year on July 1st and December 1st.  Correspondingly, they are due every year on September 14th and February 14th (unless the date falls on a weekend or holiday, in which case they are due on the next business day).

If you do not receive a tax bill, please contact the Township Hall and we will send a new one, or you can get the amount due by clicking Online Property Tax Information (this also applies to receipts).  Please be advised that it is the responsibility of the taxpayer to pay their property taxes timely, whether a tax bill has been received or not.  Failure to physically receive a bill does not excuse the obligation or due date.  

Taxable Value (TV)

TV is the figure which is used to calculate your taxes. Multiplying the TV by the millage rate, then dividing by 1,000 will determine your tax liability. TV can increase from year to year up to the rate of inflation or 5%, whichever is lower. Transfers of ownership, which “uncap” the TV, and improvements to the property can increase the TV more than the rate of inflation. TV cannot exceed the SEV for the property.

Principal Residence Exemption (PRE)

The PRE removes the school operating tax from your bill. On the tax bill or assessment change notice, the exemption is illustrated by a 100.00% if you are eligible or a 0.00% if you are not. You must file a Principal Residence Exemption (PRE) Affidavit (Form 2368) with the Assessor’s office to claim the PRE. If you own and occupy a home as your principal residence by November 1st, you are entitled to a PRE for the current tax year and all subsequent tax levies (as long as the property remains your principal residence). PRE does not affect the summer tax levy in Williamstown Township because we do not collect for schools in the summer.
