Colorado taxpayers could receive state refunds of up to $1,130 when they file taxes in 2025, depending on their filing status and gross income, state officials said. According to the Colorado Department of Revenue’s Taxation Division, single-filing taxpayers could receive between $177 and $565 in tax refunds under Colorado’s Taxpayer’s Bill of Rights, and joint-filing taxpayers could receive between $354 and $1,130, depending on their gross income bracket. TABOR is a constitutional amendment that caps the state budget and requires tax revenues collected above that to be refunded to taxpayers.
