I'm not sure on whether you're asking about personal property taxes or real estate taxes.
But if you don't pay your real estate taxes when due you'll be hit with a penalty which is interest per year that adds onto the amount due for the real estate taxes.
Then you usually have at least 3 years to pay off the owed real estate property taxes before the real estate is put up for sale at a tax auction where someone else bids on and buys your home or land from the county.
You must pay the full amount of real estate taxes due within that 3 years to keep your house or land.
For personal property taxes you usually only have 1 to 2 years to pay the personal property tax before the county will issue a warrant to the sheriff to either collect the amount of money owed on the personal property or collect and seize the personal property itself.
