The owner of the property as of January 1st of the current tax year is responsible for taxes for the entire year, unless the property changes ownership during the tax year. If there is a change of ownership, the owner of record on the following January 6 or date interest begins and any subsequent owner will be held liable for any unpaid real estate taxes.
The Tax Department does not prorate real estate taxes; this should be handled between the buyer and seller at the time of the sale. The Tax Department will attempt to send the bill to the January 1 owner of record as well as any subsequent owners. Tax liens against the property will stay until the taxes are paid in full.
