Oklahoma City's sales tax collections for the June reporting period tumbled 7.7 percent, wrapping up a year of weak results for the city's single-largest revenue source.

The city received $31.7 million this week, down from $34.4 million a year ago. The share going to the general fund to finance most day-to-day services fell just short of $16.4 million.

The balance goes to dedicated funds, including the monthly allocation of around $9 million for MAPS 3 and fractions for police, fire and the Oklahoma City Zoo.

With the oil-and-gas slump continuing and arrival of the final monthly check for fiscal 2016, annual general fund sales tax collections are down $4.1 million, or 1.9 percent, from 2015.
