The state will indeed collect a sales tax estimated to send $20 million a year to the St. Louis Zoo.

A spokeswoman for the Missouri Department of Revenue said the agency has decided it can collect the Proposition Z sales tax, which will fund a 425-acre zoo breeding facility and adventure park in north St. Louis County, among other things.

County voters on Nov. 6 overwhelmingly approved the tax, which would add 1 cent to an $8 purchase.

But the state Department of Revenue, which collects sales taxes, told the county last month that the proposition might have run afoul of a state law mandating a two-year waiting period between sales tax propositions.

County voters had approved Proposition P to support public safety in April 2017, about 18 months before Prop Z’s passage.
