Some Colorado businesses are being asked to pay more to fund the state’s unemployment-insurance fund.

The fund ran out of money in June and Colorado is one of at least 41 states borrowing money from the federal government in order to keep issuing unemployment checks.

The Denver Post reports that some businesses are facing unemployment insurance premiums more than four times higher than last year.

Companies that never had layoffs have previously paid lower premiums but are now being asked to pay more.

Don Mares, the head of the state’s labor department, said many companies with higher claims are already near paying the maximum rate – 5.4 percent of the first $10,000 an employee earns.
