Seven years can separate retirement from age 65, and Ritholtz Wealth Management treats health insurance before Medicare as a cash-flow and taxable-income decision.
COBRA generally lasts up to 18 months after employment ends and can cost up to 102% of the employer plan’s full premium, while traditional retirement-account withdrawals count toward marketplace income.
Your premium, tax credit, doctors, prescriptions, state, and household income are personal facts, so this article cannot name your best plan or promise a premium. The sequence does not change: get the coverage date, compare the available enrollment paths, then decide how each account withdrawal changes the year’s income picture.
Before Ritholtz Wealth Management suggests a withdrawal source, it maps the pension, brokerage basis, traditional accounts, and Roth accounts on the same page. That is less exciting than a market forecast. It is also what determines whether a retirement paycheck quietly makes health coverage more expensive.

Step 1: What coverage ends when the paycheck ends?
Gather the last employer benefits notice, the coverage end date, COBRA election paperwork, and the spouse’s plan summary before choosing an account withdrawal. Ritholtz Wealth Management sees people assume coverage runs through December when it actually stops on the last day of a month, or on another date set by the employer.
Losing job-based coverage generally opens a 60-day Marketplace special enrollment period under CMS rules. Voluntarily ending COBRA later, outside open enrollment, generally does not create a fresh Marketplace enrollment right. Start with the date on the paperwork, not the date you remember from a hallway conversation.
Step 2: “COBRA is always safer than a marketplace plan”
COBRA can be the sensible short bridge when changing doctors or resetting a deductible would be costly, but it is not automatically the cheapest or safest choice. It can charge up to 102% of the full employer-plan premium, while Marketplace coverage can cost less when a household has lower counted income. The useful comparison is doctors, drugs, deductible progress, enrollment timing, and monthly cash cost.
The table assumes a hypothetical couple leaving work before age 65. Its point is not to calculate a premium; it is to stop four bad shortcuts before they become an election.
A couple with active specialists and a nearly met deductible may reasonably pay for a few months of COBRA. A healthy couple with flexible doctors, little deductible progress, and low projected taxable income may favor a Marketplace plan. Ritholtz Wealth Management would price both paths before selling investments to cover either one. The old employer plan is familiar, but at up to 102% of the full premium, familiar can still mean expensive.
| Common belief | What the rule says | What it means for you |
|---|---|---|
| COBRA is employer-priced | It can cost 102% | Price it before electing |
| All stock-sale cash counts | Gain generally counts | Track basis and gain |
| IRA withdrawals are neutral | They count as income | Budget the income effect |
| Dropping COBRA opens enrollment | Usually it does not | Choose the first window carefully |
| A spouse plan has no timing | Special enrollment may apply | Check the employer’s paperwork |
Step 3: How do account withdrawals change the monthly coverage bill?
Account withdrawals can change a Marketplace premium because the cash you spend and the income counted for coverage are not always the same number. Traditional IRA and 401(k) withdrawals generally enter the relevant income measure. Tax-exempt municipal-bond interest is added back too. Qualified Roth IRA distributions generally are not counted. A brokerage sale works differently: in this simplified comparison, only the realized gain generally counts, not every dollar that lands in checking.
For illustration, hypothetical Ramon and Yolanda need $60K for a year after Ramon leaves work at age 61. Ramon is a civil engineer at a private firm. Yolanda, age 59, is a retired high-school chemistry teacher whose small state pension supplies $18K. They hold $1.1M across his 401(k), two IRAs, and a $200K brokerage account.
If they take the remaining $42K from a traditional IRA, their simplified Marketplace-income total is $18K pension + $42K IRA withdrawal = $60K. That creates the year’s cash need, but it also adds $42K of ordinary income to the coverage calculation. No mystery there.
Now assume they sell $42K from a $90K slice of their brokerage account that has $30K of embedded gain. The simplified total becomes $18K pension + $30K gain = $48K. The sale still raises $42K of cash. It does not erase capital-gains tax or premium calculations; it changes which income is counted.
That $12K difference is not a promised premium savings. Marketplace premiums and tax credits depend on household size, location, plan choice, projected income, and annual rules. Use the site’s calculator to test cash sources and gains, then verify the coverage result through the Marketplace. The IRS Form 1095-A is the paperwork used to reconcile a Marketplace premium tax credit at tax time, which is one reason a casual income estimate can become an unpleasant April surprise.
The account decision has a later echo. Medicare uses an earlier income year for certain Part B premium adjustments. Higher 2024 modified adjusted gross income can raise 2026 Part B premiums. According to CMS, the 2026 standard Part B premium is $202.90 a month for a person at or below the first income threshold ($109,000 single / $218,000 joint). The income Ramon and Yolanda report at 61 will therefore feed the Part B bill two years later. Ritholtz Wealth Management checks that future Medicare handoff before calling a low Marketplace-income year a complete win. Market investments carry risk, and principal can shrink. A diversified mix and a sensible withdrawal plan still matter while coverage premiums are being paid.
Cash received is not always counted income
A lower-income year can echo into Medicare
Before electing COBRA or Marketplace coverage, write down the exact coverage end date and separately estimate pension income, traditional-account withdrawals, taxable gains, tax-exempt interest, and qualified Roth withdrawals.
Step 4: Put the choice on the kitchen table
The spouse who handled benefits often spots the issue first. Sometimes it is an adult child who sees an unopened COBRA envelope on the counter. Either way, both spouses should compare doctors, prescriptions, network access, deductible progress, enrollment dates, and the monthly premium before one person clicks “elect.”
Run the decisions in order. First, confirm the coverage end date. Second, ask the spouse’s employer about its special-enrollment path. Third, price COBRA. Fourth, price Marketplace options. Fifth, make a withdrawal list that shows the income created by each cash source. This is where Ritholtz Wealth Management can separate an account balance from the tax character of the money inside it.
Paperwork errors have a real price. Voluntarily canceling COBRA after the initial election window without checking Marketplace enrollment rights can leave a household waiting for open enrollment, because that cancellation generally does not create a new special enrollment period. Undoing it may mean asking the former benefits office whether reinstatement is available, while carrying an unwanted coverage gap if it is not.
Use this short checklist before you make the election:
Price coverage before changing withdrawals
- Coverage: Confirm doctors, prescriptions, networks, deductible progress, and enrollment dates.
- Cash flow: List pension income, taxable interest, realized gains, traditional withdrawals, and qualified Roth withdrawals separately.
- Basis records: Ask the brokerage custodian for purchase-basis paperwork before selling shares.
- Spouse plan: Confirm the enrollment path and its due date with the benefits office.
Your questions about health insurance before Medicare, answered
My employer offers COBRA, should I elect it while I compare marketplace plans?
Electing COBRA can preserve the existing plan while you gather prices, but do not assume you can drop it later and then enroll in a Marketplace plan whenever you want. Confirm the employer’s election due date, the Marketplace special-enrollment dates, and whether your doctors and prescriptions make a short COBRA bridge worth its full premium.
When should I enroll in Medicare if I retire before age 65?
Your Medicare initial enrollment period lasts seven months, starting three months before the month you turn age 65. Put that window on the household calendar well before current coverage ends. If you keep employer coverage past 65, ask the benefits office and Medicare directly about the enrollment timing that applies to that coverage.
Can my adult daughter help compare marketplace plans without becoming responsible for my coverage?
Yes. An adult child can help you read plan networks, prescription lists, and enrollment dates without becoming financially responsible for the policy. Keep control of account passwords and consent choices, and have the household member whose name is on the application confirm projected income and submit the final enrollment.
Does selling shares from my brokerage account raise marketplace income?
Selling shares can raise Marketplace income through the realized capital gain, not usually through the full sale proceeds. A $42K sale with $30K of gain produces $42K of cash but, in a simplified comparison, adds $30K of gain. Confirm your basis records before estimating income.
What happens if I miss the 60-day marketplace enrollment window after work coverage ends?
Missing the 60-day special enrollment period can mean waiting until the next open enrollment period unless another qualifying event applies. Contact the Marketplace promptly if you believe the coverage-end date or employer paperwork was wrong. Keep dated copies of the benefits notice and COBRA materials.
Can I contribute to an HSA while I am on COBRA?
COBRA coverage does not automatically make you eligible to contribute to a health savings account. HSA eligibility depends on being covered by an HSA-qualified high-deductible health plan and meeting other IRS conditions. Check the plan’s HSA status and your eligibility for each month before making a contribution.
Step 5: What changes as Medicare gets closer?
Medicare’s initial enrollment period lasts seven months, beginning three months before the month a person turns age 65, according to CMS. Ramon and Yolanda reach Medicare at different times, so one person’s enrollment does not automatically fix the other person’s coverage; revisit household income when either person changes plans.
Ritholtz Wealth Management can organize coverage dates, account withdrawals, and questions for a tax professional or benefits office. The first conversation can cover the $500K investable-assets minimum, with fees discussed openly and confirmed in writing before work begins.
The cash you spend and the income counted for coverage are not always the same number.
