Retiring Three Years Apart: Healthcare, Income, and Timing

Financial Snapshot

• Tom, 64, retiring now; Lisa, 61, self employed with about $30,000 per year of part time income expected through age 63
• Tom's 401(k) holds $1,900,000, all pretax; Lisa's SEP IRA holds $450,000
• Joint taxable account of $500,000, roughly half of it cost basis, plus $150,000 in cash
• Home valued near $900,000, purchased years ago for about $400,000, with a $120,000 mortgage remaining
• Combined spending goal of roughly $110,000 per year
• Both covered today under Tom's employer health plan, which ends at his retirement

The Challenge

This plan has to solve a timing problem, not a money problem. Tom is twelve months from Medicare. Lisa is four years out. Health coverage for the gap years is priced on income, and the household's instinct, to start Roth conversions immediately while wages are low, would raise the very income number that sets their premiums. Layer on two Social Security decisions and a recurring argument about selling the house, and every choice was tangled in every other choice. This is common. It is also solvable in a specific order.

Our Approach

We priced the healthcare bridge both ways. COBRA would continue their current plan for 18 months at full cost plus an administrative fee, carrying Tom past his Medicare start but leaving Lisa exposed at month nineteen with more than two years still to cover. The marketplace alternative runs on modified adjusted gross income: premium tax credits shrink as income rises, and the math is unforgiving near the eligibility lines. In this illustration, the marketplace with deliberately managed income priced meaningfully below COBRA over the full four year bridge. That is not a universal result.

So the early retirement years run on a specific fuel mix: Lisa's part time income, the cash reserve, and withdrawals of cost basis from the taxable account, which generate little taxable income per dollar of spending. That holds their modified adjusted gross income low enough to keep meaningful premium credits while Lisa needs marketplace coverage. It also means we told them to wait on Roth conversions, which surprised them. Conversions are income, and income is exactly what this phase needs less of. The conversions are sequenced, not abandoned.

On claiming, we staggered. Lisa plans to claim her own benefit at 65, after she has stopped working, so the earnings test never touches her. Tom, the higher earner, delays to 70. His delay is not really about Tom: whichever spouse lives longer inherits the larger check as a survivor benefit, so delaying the bigger record functions as longevity protection for both of them. Tom enrolls in Medicare at 65 on schedule, and we prepare him for the two year IRMAA lookback, since his first premiums reflect income from his final working years.

The conversion window opens once Lisa reaches Medicare and premium credits stop mattering. From roughly Tom's age 68 to 75, when required minimum distributions begin for their birth years under current law, we fill brackets deliberately while keeping modified adjusted gross income under the $218,000 joint IRMAA threshold. Under conservative assumptions, an estimated $500,000 to $600,000 could potentially move to Roth across that window. Part of the purpose is survivor protection: after a first death, the survivor files as a single taxpayer at compressed brackets, and a smaller pretax balance is one of the few defenses you can build in advance.

We also answered the house question with arithmetic instead of opinion. Their gain, roughly $500,000, fits inside the section 121 exclusion for a married couple, so tax is not the obstacle. The obstacle is that selling costs, moving costs, and the price of a smaller home they would actually enjoy consume most of the equity. Our model showed an estimated net release near $200,000, useful but not decisive. The plan works without it, so the decision reverted to a lifestyle preference, revisited without pressure. The portfolio itself runs under our Compound Cultivator methodology, with bonds held pretax and equities weighted toward the taxable account and future Roth dollars.

Projected Outcomes

A priced healthcare bridge: Marketplace coverage with deliberately managed income is designed to potentially cost meaningfully less than COBRA across the four year gap under conservative assumptions, with cash and basis withdrawals protecting credit eligibility.

Claiming that protects the survivor: Lisa at 65, Tom at 70. Delaying the larger record is designed to raise the benefit whichever spouse eventually keeps, regardless of who outlives whom.

Conversions with a start date: An estimated $500,000 to $600,000 of Roth conversions is mapped to Tom's ages 68 through 75, sized annually under the $218,000 joint IRMAA threshold and designed to potentially reduce lifetime taxes for the household and the eventual survivor.

A downsizing answer without pressure: Estimated net equity release near $200,000 after costs. The plan does not depend on it, so the house decision stays a preference, not a requirement.

Methodology

Tom and Lisa are a hypothetical composite illustration, and every number is illustrative rather than a prediction. In practice, we would review income against the premium credit thresholds each fall before marketplace open enrollment, size conversions each December once the year's income is known, revisit the claiming plan annually until each spouse files, and meet twice a year to keep the sequence honest as health, markets, and preferences change.
