The chorus demanding that organizations exempt from District taxes pay the piper has swelled by one notable member. Last week, Ward 1 Councilmember Frank Smith proposed a resolution that would require the mayor to investigate whether the city could create a new property tax assessment class or a payment-in-lieu-of-taxes (PILOT) to wring revenue from nonprofit deadbeats. Councilmember Kathy Patterson (D-Ward 3) has already introduced legislation requiring a detailed list of the tax-free. And At-Large Councilmember John Ray introduced a bill that asks Congress’ permission to tax the Federal Home Mortgage Association (Fannie Mae), Freddie Mac, and Sallie Mae. The city forgoes more than $200 million in property taxes alone from these three companies. Congressional legislation also exempts Fannie Mae from nearly $300 million in corporate taxes. Later this month, Smith is expected to try to impose a PILOT.
