Expect Colorado’s upcoming state tax refund to be the last big one for a while. Forecasts by legislative economists released on Thursday predict a softening of economic conditions, tighter budget forecasts and recent changes to state law. Together, those are expected to decrease state refunds due under Colorado’s Taxpayer’s Bill of Rights, or TABOR, from recent historic highs. Projections put TABOR refunds for individual filers at between $181 and $571 this upcoming tax season, depending on household income.
