Roll Call is reporting (sub. req’d) that the D.C. Office of Tax and Revenue won’t impose any penalties on four members of Congress that were recently found to be illegally exploiting a tax break for D.C. homeowners. The representatives — which include Phil Gingrey (R-Ga.), Steve King (R-Iowa), Tom Petri (R-Wis.) and Mike Rogers (R-Ala.) — will only be charged for the back taxes they owe. D.C. officials also announced that Rep. Betty McCollum (D-Minn.) was similarly found to be exploiting the tax break, and that many of the members only gained access to the break because of a city policy of granting it to new homeowners based on the status of previous owners. The tax break, known as the homestead exemption, offers District residents a deduction on the assessed value of their D.C. home and limits annual property tax increases. In 2005 22 senators were found to be taking advantage of it, even though it is limited to District residents (which members of Congress cannot be).
