Since I'm a fairly new member, I'm not sure if we get tax statements; however, I do know that the amount of tax we pay is listed in the dues statement.
We previously owned a Nevada timeshare for many years and never received a tax statement. The maintainence fee/dues statement included the tax information for our interval which we used for our IRS return.
That's required with any mortage (unless perhaps the amount is really small).
We financed when we first bought, but then with rates so low and property values around me going up, we took out a home equiy loan and paid it off. Same tax benefit, but much, MUCH lower interest rate.
