An Illinois tax agency ruled that former President Donald Trump must reimburse $ 1 million on the 2011 tax bill for the downtown Chicago skyscraper, but Cook County officials say doing their best to block the refund, the Associated Press reported.

The Chicago Sun-Times reported that the problem was that the Cook County Review Board overestimated the value of hotel rooms and retail space at the Trump International Hotel & Tower. The Illinois Land Tax Appeal Board voted 5-0 to lower the property’s commercial property valuation last month.

The Cook County state attorney challenged the refund and filed a lawsuit with the Illinois Court of Appeals to block it. The vote would mean Trump owes $ 1.03 million, which would come from property taxes owed to the city of Chicago, Chicago public schools and several other government agencies. Schools stand to lose about $ 540,000 if repayment is not blocked.

The dispute is the latest chapter in a long legal battle over Trump’s tax bills that began over 12 years ago and has led to more than $ 14 million in tax relief for Trump. It also involves not only a former president who is in the midst of a multitude of legal battles, but a Chicago city councilor whose own legal issues have been in the headlines in Chicago for months.

Alderman Edward M. Burke, whose former law firm, Klafter & Burke, won the tax breaks for Trump, has been charged with federal charges he has prevented businesses from obtaining municipal permits in unless they hire the firm. He has pleaded not guilty and is awaiting trial.

The dispute over high-rise building tax bills has its own long history. Originally, the state agency rejected Trump’s argument that vacant stores were of no value because he couldn’t find any tenants to rent them. A state agency hearing officer dismissed Trump’s argument that the building’s vacant stores were of no value because he couldn’t rent them. But a staff member later wrote a report that Trump was entitled to the refund.

The agency delayed action on the case until Trump was removed from office and voted in June to lower the valuation of the building’s commercial property.
