Hertz, owing $700K in Pittsburgh airport taxes, penalties, says it mistakenly paid the state

A western Pennsylvania county says rental car giant Hertz owes more than $700,000 in unpaid taxes, interest and penalties after the company directed about half of a $2-a-day rental tax's proceeds into state coffers.

Hertz said Tuesday it shouldn't have to pay the penalties because it didn't intend to deprive Allegheny County when it mistakenly sent $435,577 in Pittsburgh International Airport taxes to the state.

The company blamed "administrative oversight."

The county treasurer's office says Hertz must pay the full amount within 10 days or request a hearing. The county says Hertz could try to get a refund from the state.

A county audit discovered the missing taxes. It also found Hertz owed the airport $17,153 in unreported revenue.

Hertz says it's working with the county to resolve the matter.
