taxes and financial obligations citing a fixed dollar amount are most likely payable at that fixed rate without regard for inflation.... you don't want to be unable to pay your taxes as Mary Anna Custis Lee was during the Civil War... unable to pay the taxes in person, and a personal representative not allowed to do so,and something about her husband's occupation, she ended up with "Yankees buried in the rose garden" .... near the Custis Lee mansion that was defaulted to the US government.... now Arlington National Cemetery
