Health Insurance Tax Credit at 65 | Skinner Wealth Strategies

Key Takeaways

What You Need to Know Before You Turn 65

1

Once you are eligible for Medicare — typically at age 65 — you are no longer eligible for a premium tax credit (PTC) on an ACA Marketplace plan, regardless of your income.
2

The window between early retirement and age 65 is when the ACA premium tax credit may provide the most value — and when income management strategies can significantly affect how much credit you qualify for.
3

Decisions about Roth conversions, retirement account withdrawals, and other taxable income sources in your early 60s may directly affect your eligibility for the credit — making coordinated income planning essential.
4

Connecticut residents face additional complexity: CT taxes most retirement income, which can affect your modified adjusted gross income (MAGI) and in turn your credit eligibility in ways that require careful planning.
5

Working with a CRPC®-credentialed retirement planner before you retire — not after — gives you the most flexibility to structure income in a way that may maximize available credits during the pre-Medicare years.

Understanding the ACA Credit

How the Premium Tax Credit Works — and When It Ends

The Affordable Care Act (ACA) premium tax credit is a federal subsidy that helps eligible individuals and families pay for health insurance purchased through the official Marketplace. Eligibility is based primarily on your household income relative to the federal poverty level (FPL), as well as your access to other qualifying coverage — including Medicare.

According to the IRS, you cannot claim a premium tax credit for any month in which you are eligible for Medicare — Part A, Part B, or both. This is true even if you choose not to enroll in Medicare. In other words, eligibility for Medicare — not enrollment — is the disqualifying factor.

For most people, Medicare eligibility begins at age 65. At that point, ACA Marketplace coverage paired with premium tax credits is no longer an option. This transition is automatic and applies regardless of your income level, meaning high-income and lower-income individuals alike lose access to the credit at 65.

Why This Matters for Pre-Retirees

The Pre-Medicare Window Is a Critical Planning Opportunity

For those who retire before 65, the years between retirement and Medicare eligibility may represent one of the most financially consequential — and frequently overlooked — planning periods in retirement.

Income Planning Strategy

How Your Retirement Income Affects Your ACA Credit Eligibility

The premium tax credit is income-based. Eligibility is determined by your Modified Adjusted Gross Income (MAGI) as a percentage of the federal poverty level (FPL). For 2025, to qualify for a credit, your household MAGI generally must fall between 100% and 400% of the FPL — though expanded subsidy provisions have extended eligibility above 400% in recent years, subject to legislative changes.

This means that in the years before you turn 65, what you take out of your retirement accounts — and when — can directly affect whether you qualify for a credit and how large it may be. Common income sources that count toward MAGI include:

1

Traditional IRA and 401(k) Withdrawals

Distributions from pre-tax retirement accounts are counted as ordinary income and increase your MAGI. Large withdrawals in a single year — even if used for living expenses — can push your income above subsidy thresholds.

2

Roth Conversions

Converting pre-tax funds to a Roth IRA generates taxable income in the year of conversion, which raises MAGI. Timing and sizing Roth conversions carefully in the pre-Medicare years requires balancing long-term tax benefits against near-term subsidy eligibility — a trade-off that depends heavily on your individual financial picture.

3

Capital Gains and Dividends

Realized capital gains — including from taxable brokerage accounts — are included in MAGI. Even long-term capital gains at preferential rates count toward the income threshold used to calculate your credit.

4

Social Security Benefits

Up to 85% of Social Security benefits may be included in your MAGI, depending on your combined income. If you begin Social Security before 65, those payments will count toward the calculation.

5

Part-Time Work or Consulting Income

Earned income in the early retirement years — whether from part-time work, a board position, or consulting — is counted as ordinary income and affects your MAGI in the same way as wages.

Income planning for the pre-Medicare years involves trade-offs. Reducing MAGI to maximize a premium tax credit may not always align with other long-term financial goals, such as minimizing future Required Minimum Distributions (RMDs) or building tax-free retirement income. A coordinated approach — addressing healthcare costs, tax efficiency, and income distribution together — is designed to weigh all of these factors. Results vary by individual situation.

Connecticut Context

What Connecticut Pre-Retirees Need to Know

Connecticut residents face a layer of complexity that residents of many other states do not. Connecticut taxes most forms of retirement income — including pension income, IRA distributions, and Social Security benefits above certain thresholds — which can affect your MAGI calculation and, in turn, your ACA premium tax credit eligibility in the pre-Medicare years.

This means that the standard federal-level analysis of subsidy eligibility may not fully capture your situation. Retirement account distributions that push you above a subsidy threshold may also carry a Connecticut state income tax consequence, compounding the financial impact of a poorly timed withdrawal or conversion.

For pre-retirees in Fairfield County and the greater Connecticut area — particularly those with $1 million or more in retirement savings — the interplay between federal premium tax credit eligibility, CT state income tax, and long-term income distribution planning makes coordinated, advisor-guided planning especially valuable in the years leading up to retirement and Medicare enrollment.

Planning Considerations

Connecticut-Specific Factors That May Affect Your Credit

A

CT taxes IRA and 401(k) distributions. Unlike some states, Connecticut taxes pre-tax retirement account withdrawals as ordinary income, which increases your MAGI for federal subsidy purposes.
B

Social Security may be partially taxable in CT. Connecticut taxes Social Security benefits for individuals with higher adjusted gross incomes, adding to the MAGI used in subsidy calculations.
C

Connecticut's cost of living is high. Healthcare premiums on the CT marketplace tend to reflect the state's higher cost structure, making the value of the premium tax credit — where eligible — potentially more significant than in lower-cost states.
D

Access Healthy CT. Connecticut operates its own state-based ACA Marketplace (Access Health CT), which may have different plan options and timelines than the federal exchange. Pre-retirees should be aware of enrollment periods specific to the CT marketplace.

State tax rules are subject to change. Consult a qualified financial or tax professional for guidance specific to your situation.

Frequently Asked Questions

Common Questions About Health Insurance Tax Credits and Age 65

Do you lose your health insurance premium tax credit at 65?

Yes. Once you become eligible for Medicare — which for most people occurs at age 65 — you are no longer eligible for a premium tax credit on an ACA Marketplace plan. This is true even if you choose not to enroll in Medicare. According to the IRS, Medicare eligibility (not enrollment) is the disqualifying factor. Your ACA coverage and any associated premium tax credit will end when your Medicare coverage begins.

What happens to my private health insurance when I turn 65?

If you have been purchasing coverage through the ACA Marketplace, your plan — and any premium tax credit — will end when you become Medicare-eligible. You should enroll in Medicare during your Initial Enrollment Period (the seven-month window around your 65th birthday) to avoid late enrollment penalties. If you have employer-sponsored coverage through a current employer at age 65, different rules may apply, and it is worth reviewing your options carefully before making any coverage changes.

Can you get ACA Marketplace coverage after age 65?

Generally, no — not with a premium tax credit. Once you are eligible for Medicare, you cannot receive a premium tax credit for Marketplace coverage. While it may be technically possible to purchase a Marketplace plan without a subsidy at 65, doing so while Medicare-eligible would result in a gap in Part A enrollment that could trigger late enrollment penalties. For most people, Medicare is the appropriate primary coverage at 65 and beyond.

What disqualifies you from the premium tax credit before age 65?

Several factors can disqualify you from receiving the premium tax credit, including: income below 100% of the federal poverty level; eligibility for Medicaid; access to affordable employer-sponsored health insurance (defined by IRS affordability standards); being claimed as a dependent on someone else's tax return; or filing your taxes as Married Filing Separately in most cases. Income above the applicable threshold — currently based on expanded subsidy rules that are subject to legislative changes — may also reduce or eliminate the credit.

What are the income limits for premium tax credits?

Premium tax credit eligibility is based on your household MAGI as a percentage of the federal poverty level (FPL). Historically, the credit was available to households between 100% and 400% of the FPL. Enhanced subsidy provisions that have been extended in recent years may allow eligibility above 400% of the FPL, though these provisions are subject to change based on legislation. For 2025, the FPL for a single individual is approximately $15,650, according to the Department of Health and Human Services — meaning 400% FPL is approximately $62,600. Thresholds adjust annually and vary by household size.

Why might I not be getting a premium tax credit even if I think I qualify?

Common reasons include income that has increased beyond the subsidy threshold mid-year, failure to report income changes to the Marketplace promptly, access to employer-sponsored coverage that meets the IRS affordability standard, or filing status issues. It is also possible that advance premium tax credit payments were applied during the year and reconciled at tax time, resulting in a repayment rather than an additional credit. If you believe you should qualify but are not receiving the credit, a qualified financial planner or tax professional can help review your situation.

Does the federal government have a separate health plan for people over 65?

Yes — Medicare is the federal health insurance program for individuals age 65 and older (and certain younger individuals with qualifying disabilities). Medicare consists of Part A (hospital insurance), Part B (medical insurance), Part D (prescription drug coverage), and optional Medicare Advantage plans (Part C) offered by private insurers. Medicare replaces ACA Marketplace coverage at 65 and is generally the primary coverage for eligible individuals. Supplemental coverage — commonly called Medigap or Medicare Supplement insurance — can help cover costs Medicare does not pay.
