This thread is actually a good reminder. It’s time to pay the second half of my taxes on my condo, because they’re due on June 15.
In the US, if you have a mortgage, then property taxes are usually collected by the mortgage servicer (along with insurance), and put in an escrow account. When due, the money in the escrow account is used to pay the property taxes to the county. There is no extra interaction necessary by the homeowner: pay the mortgage bill, which includes taxes, and it is all taken care of.
I do not have a mortgage on the condo, so I have to remember to pay the taxes myself. I get one bill from the county. I then have the choice of making a single payment, or paying half in February, and half in June. There is no discount for paying the full amount early.
