Toward the end of December you get the actual bill. It's just a slip of paper and could be easily overlooked.
On that bill it will breakout what you paid in taxes for the current year. For example, the bill you get in December 2004 will have a line showing the actual ad valorem tax (property) tax assessed. This is what you might be able to deduct from your 2004 Income Tax. The bill will also show the estimate you are being charged for the 2005 property tax. You need to be careful about which line you are looking at.
And yes, it really is packed between Christmas and New Year's but it's also a heck of a lot of fun!
