Almost every Coloradan eligible for a tax refund check should have it in the mail, if they haven’t cashed it already, according to state officials. About 2.4 million checks have been sent out, each for $750 for individuals and $1,500 for joint filers. The rebates are due to the state’s $3.5 billion budget surplus and constitutional limits on tax collection. Department of Revenue spokesperson Suzanne Karrer said there are “a small number” of checks still being processed, but they should be sent out within a week.
