If the government shutdown continues through Feb. 15, it could cost the District more than $85 million in lost tax revenue, according to a new report from D.C.’s chief financial officer.

To put that into context, $85 million would be most of the District’s $100 million annual budget for its Affordable Housing Trust Fund.

The losses accelerate the longer the shutdown continues, the report says, as federal workers further decrease their spending and the furlough begins to bleed into tourism season. If the shutdown drags on through the second week of March, the CFO says, weekly losses rise to $15.23 million per week, from the current $11.67 million.

These estimates don’t include short-term losses from direct federal workers temporarily living without a paycheck, because those wages are guaranteed to be repaid. But they do include income tax that won’t be paid by federal contractors, because they can’t expect to be reimbursed.

Most of the losses come from foregone sales taxes and related revenues, the report says, from things like slumping restaurant sales, increased hotel vacancies, reduced retail activity, and a loss in parking revenue.

About 145,000 District residents are affected by the shutdown, the report says.

Metro has said the furlough is costing the transit system about $400,000 per weekday. Some restaurants have reported average losses of 20 percent, with some reaching as high as 60 percent, according to the Restaurant Association of Metropolitan Washington.

The CFO’s report does contain some good news. It says D.C. is in a decent position to absorb a temporary loss in revenue because it’s in good fiscal health, and the city has about 60 days of operating reserves.

“However,” the report adds, “the District is required to balance expenses with projected revenues, and this downturn may require adjustments to future spending unless the shutdown is shortly ended and the strong economic growth resumes.”
