Today is Tax Day, that annual deadline by which Americans must engage in the only thing that is certain besides death, as the saying goes: Cutting a check to the Internal Revenue Service. (Unless they?re among the nearly 80 percent that get refunds.) That the IRS is not beloved is an understatement: Years of polling shows that most Americans think the agency does a middling job at best, and believe that it uses its oversight of the tax system for nefarious political ends. A Gallup poll this year showed only the scandal-plagued Veterans Administration has a worse rating among Americans than our beleaguered tax collectors.
