Whether you can deduct property taxes depends on your particular situation, e.g., if you own a main home and DVC is your only "second" home, you can likely deduct, but if you own another second home you have an issue. Check with an accountant to determine whether you can actually deduct.
The statement you got that provided your 2007 dues and estimated taxes that you have to pay for the 2007 year also has on it the property taxes paid in 2006. Thus, it is the document that gives you the property taxes that are deductible for the 2006 year, assuming you can deduct. Also, property taxes are only a portion of the dues and you cannot claim the rest of your dues as a deduction.
You cannot deduct from your 2006 tax year the estimated 2007 property taxes that you paid.
