Always check the PIN on your bill against the PIN(s) on your sale or mortgage documents to make sure that the bill matches the property that you own.

There are two reasons a home may receive more than one tax bill:

First, it is not uncommon for a residence to sit on more than one parcel of land, each with its own Property Index Number (PIN). A bill is issued for each PIN. If your home straddles two PINs, then the home value will be split between the PINs.

Second, if you live in a condominium, it is quite common for your garage to be assigned its own PIN. This is a choice made by your condominium association. In this case, you will receive a tax bill for each PIN (of course, the tax bill for your garage will be much less than the tax bill for your residence).
