Big-box stores are going to court to get big concessions on their property taxes

Some big-box stores are claiming that, for local property tax assessment purposes, their buildings should be valued at the fair market value of a vacant store of similar size -- buildings that are notoriously hard to sell. Often, that fair market price is a fraction of the value of the new store's building. The strategy is called the "dark store tax tactic" and it's a terrible deal for cities.
