Why Colorado Flat Tax Rocks
Colorado used to have graduated tax long ago. Now flat 4.4 percent since 2022. Voters approved cut from 4.55 to 4.4. Simple and stable. You can do math in head. Plus Colorado has TABOR. That is Taxpayer Bill of Rights. If state collects too much, they refund money to you. In 2024 refund was 800 per single filer. In 2025 expected 850. So real rate even lower.
Another plus is no tax on Social Security in Colorado for many retirees now. Law changed in 2022. Full exempt if you are 65 plus. Military retirement exempt. So Denver is retiree friendly plus young tech workers love Boulder and Denver tech scene. No local city income tax either. Only state.
