Cajundome officials are making an appeal to the state supreme court, about their 8 percent sales tax .
The Cajundome director, Greg Davis, says the tax cost them between $400,000 to $500,000 a year.
He says they can pass about half of that on to the customer, but its still creating a financial burden.
"If we're able to get the supreme court to rule in our favor then we can improve our financial position tremendously and go forward."
Officials have until march 4th to appeal.
