A 2NEWS Investigation discovered $18 million is owed in late taxes to Tulsa County for 2013.

2NEWS Investigator Marla Carter tracked down who owes the most.
Some are living in mansions. Others are owners of million dollar business developments. The taxes that are owed is money that's supposed to go to schools and county services.
"It's an interesting choice that people make not to pay. I mean, I wouldn't want my name on that list, if I had a business," said Tulsa County Commissioner Karen Keith.
