Early Retirement and ACA Subsidies in Colorado
When you retire before Medicare and buy coverage through Connect for Health Colorado, estimate income for the full calendar year of coverage. A final paycheck, a taxable Roth conversion or a gain on a brokerage sale can change how much help you qualify for. Project the tax and health coverage costs together before choosing how to fund your spending.
Start With the Coverage Year and Your Tax Household
If you leave work in September, the Marketplace income estimate for that year generally includes your wages from January through September and the rest of the household income expected through December. Build a separate estimate for the next coverage year. Include your spouse’s income when applicable, even if only one of you needs a Marketplace plan. Income alone does not determine eligibility. Review other coverage available to each household member and use the applicable year’s rules. See Connect for Health Colorado’s financial help guide and the IRS premium tax credit eligibility rules.
What Counts as Income for ACA Subsidies?
For the federal premium tax credit, household income uses modified adjusted gross income (MAGI) for you and applicable family members who must file a federal return. Start with federal adjusted gross income and include the applicable add-backs for tax-exempt interest, excluded foreign income and nontaxable Social Security benefits. The standard deduction does not reduce adjusted gross income. See HealthCare.gov’s income guide.
- Final pay and investment income. Include taxable wages, bonuses, interest and dividends. Realized gains generally enter the calculation even when a gain qualifies for a 0% federal long-term capital gains rate.
- Traditional retirement withdrawals and Roth conversions. Include the taxable portion. A conversion can raise household income even when the money moves directly from one retirement account to another. See IRS Publication 590-A.
- Cash, brokerage proceeds and Roth withdrawals. Spending existing cash principal generally adds no income. A taxable brokerage sale generally contributes the gain or loss after basis rather than the full proceeds. Qualified Roth distributions generally stay out of income. Check the distribution rules before assuming Roth funds are available tax-free. See IRS capital gains guidance and IRS Publication 590-B.
Compare Marketplace Income and Cash Available for Spending
Suppose a Colorado couple projects $50,000 of Marketplace household income before the choices below. They need $20,000 for spending and also want to know what a Roth conversion would do. Each row starts with the same $50,000 projection.
| Scenario | Cash available before taxes | Estimated household MAGI |
|---|---|---|
| Use $20,000 of existing cash | $20,000 | $50,000 |
| Sell $20,000 of investments with $12,000 of basis | $20,000 | $58,000 |
| Use $20,000 of cash and convert $20,000 that is fully taxable | $20,000 | $70,000 |
The example assumes no other income changes or capital losses. The conversion moves money between retirement accounts. The couple would still need to plan for tax and any change in net premiums. Actual credits depend on household and coverage facts, including the applicable benchmark premium and eligibility rules. Colorado Premium Assistance has its own rules. Use the Marketplace’s coverage-year estimate for each scenario.
Update the Marketplace and Reconcile Advance Credits
If you take the federal premium tax credit in advance, update Connect for Health Colorado when income, household size or coverage eligibility changes. Use Form 1095-A and Form 8962 to reconcile advance payments on your federal return. Beginning with tax year 2026, federal repayment caps for excess advance credits were removed. Check the applicable rules when preparing the return. See IRS guidance on excess advance credit repayment.
What to Review Before You Convert or Sell
- Estimate income for the rest of the current calendar year and build a second estimate for next year.
- Separate your cash spending need from the taxable amounts produced by each possible withdrawal or sale.
- Compare federal and Colorado tax, estimated health premiums after assistance and cash required to pay both. Leave room to revisit the assumptions if a bonus, dividend or sale changes the projection.
- Record the planned decisions and when you will update the Marketplace, your tax projection and any estimated tax payments.
