Rutger is over this afternoon on a business trip and he took a look at my tax returns. The key part I missed was that the taxes are set based upon the owner of the property as of January 1, 2009.
Since I didn't register the house and land until October, Tony was still the official owner, and so I had no tax exposure this year. I filed online with just a couple of clicks.
I'll talk to Tony when I'm there in April about any bills he received for our land in 2009. Even though I wasn't yet registered officially, I should pay for those myself.
