One property tax appeal from a Vicksburg casino continued its way through the court system while another received a court date.

Respective counsel for Warren County and Ameristar Casino intend to call expert witnesses to the stand when the two sides appear in circuit court July 8 to hash out differences in opinion over the casino’s tax bill for 2013. The case is before Circuit Judge M. James Chaney.

In case briefs, Ameristar argues its taxes for 2013 should be based on a true value of $136.2 million instead of the $178.4 million that appears on property tax rolls OK’d when county supervisors approved its 2013-14 budget. The bill would be about $2.5 million instead of the $3.3 million under the current calculation, case records show.

Riverwalk Casino’s appeal goes before Judge Chaney next year, after the county approves its 2014-15 budget. Two possible dates, March 23, 2015 and March 30, 2015 appeared in the most recent scheduling order. Both Riverwalk and Ameristar were two of 18 property owners who formally protested their tax liability last August when the county board met to consider any changes to the rolls. Both had also sued the county in 2010 over property taxes; both suits ended in agreements that roughly split the difference between initial calculations and what the casinos sought.

Lawyers for the Warrenton Road casino oppose a $45.3 million true value assigned to its real property this year. It is arguing for a $28.6 million true value, based on calculations court briefs say were the basis of a suit the casino has filed over its 2010 taxes. The assessment on Riverwalk’s equipment, or personal property, was among seven values lowered by the board upon further review of all 18 objections. It was taken down to $16.3 million, or $881,000 less than first calculated. The board left the true value of the real estate alone, however.

Supervisors met in closed session on Monday on both cases but announced no action on either matter. Both casinos’ original parent entities were sold in the past two years — Ameristar to Pinnacle in 2013 in a $2.8 billion deal and Riverwalk to Churchill Downs in 2012 for $141 million.
