Colorado retirement income tax: Denver pensions and Social Security checks
Colorado offers conditional subtractions for certain retirement income included federally. Social Security, pensions and IRA distributions need separate checks, and the same income cannot be subtracted twice.

Does Colorado tax pensions and Social Security?
Start with the Colorado publication’s qualifying-income sections. Age, the type of payment and the amount included federally affect the subtraction. The Social Security section has its own tax-year, age and income conditions; a headline pension cap is not the full rule.
The guidance explains that a Social Security subtraction can reduce the subtraction available for other pension income. It also prohibits claiming multiple subtractions for the same income. Ask the preparer to reconcile the benefits rather than adding separate headline allowances together.

Joint returns and unusual payments need individual records
Colorado requires each spouse to determine eligibility and qualifying income separately. An unused pension allowance is not automatically transferable between spouses. Preserve each payer’s statement and identify which person received the income.
Premature IRA/self-employed-plan distributions, death benefits, railroad benefits and previously taxed PERA/DPSRS contributions have distinct rules. Flag the issue for review; this page does not decide a distribution code, calculate a subtraction or recommend a withdrawal.
Keep Denver local questions and federal returns separate
If you continue working, run a business or receive other income in the Denver region, describe that separately. A retirement-income subtraction does not decide every work-location or business-filing question.
Federal pension/annuity reporting and Social Security benefit reporting use different rules from Colorado’s subtractions. Request a written scope covering federal and state returns, any residence change and notice support.

Bring a payer-by-payer records list
Group each plan or benefit separately before requesting preparation or review. A summary lets a professional price the work without receiving identity documents in an initial directory inquiry.
- 1099-R statements, corrected forms, SSA-1099 and any railroad benefit statements.
- Plan type, retirement/separation dates, contribution history and prior state adjustments.
- Withdrawal, transfer, inherited-account or conversion records, with dates and the payer’s description.
- Residence/move dates, other income and withholding; ask who handles federal, state and any separate local questions.
A retirement-income question does not settle TABOR eligibility. Use the Colorado TABOR claim-year and deadline guide.
Selling an investment is a separate question from receiving retirement income. Use the Colorado capital-gains reporting and subtraction guide.
Ask a professional about your situation
Ask about the particular plan, distribution, residence history and federal/state returns. Separate unusual-payment review and notice work in the quote. Directory listings do not certify retirement-income specialists or determine eligibility.
Compare professional qualifications and questions to ask. Keep personal tax documents private; this directory does not receive returns, identity documents or portal credentials.
