What a marketplace subsidy actually depends on
This is the single most misunderstood thing about buying your own health coverage before 65, and the misunderstanding costs people real money — usually by convincing them coverage is unaffordable before they've actually checked.
It's about income, not assets
A marketplace subsidy looks at your household income for the coverage year. It does not look at how much you have in savings, in a 401(k), or in home equity.
So someone with a substantial nest egg and a modest amount of actual income this year can qualify for meaningful help, while someone with far less saved but a full salary may not. That feels counterintuitive, and it's why "we assumed we'd earn too much" is such a common and expensive assumption.
The part that makes it plannable
Because it's based on income for the year you're covered, and because a retiree's income is often assembled deliberately — from a pension, from withdrawals, from when you start Social Security — that number is not always fixed.
Which account you draw from, and when, can change it. Timing a Roth conversion can change it. Realising a capital gain in December rather than January can change it.
The threshold that matters, and why it's back
There is an income level above which the subsidy stops entirely.
For several years that edge was softened, so going slightly over it meant losing a little help rather than all of it. As of 2026 the hard cutoff has returned. Being modestly over the line can mean the difference between substantial help and none at all.
I'm deliberately not printing the figure here, because it changes every year and a stale number on a website is worse than no number. What matters is the shape: this is a cliff, not a slope, and if your income is anywhere near it, the exact number for the year you're planning is worth knowing before you decide anything.
What this means practically
If you're thinking about retiring before 65 — or you already have — the sequence that works is:
- Work out what your income will realistically be for the coverage year.
- Find out where that sits relative to the current threshold.
- Then look at plans, with the subsidy already factored in.
Doing it in the other order is how people conclude coverage is unaffordable. The sticker price and what you'd actually pay are frequently very different numbers.
Estimating, and getting it wrong
You're estimating a year that hasn't happened, so you will be somewhat wrong. That's expected and built into the system — it reconciles on your tax return, so an over- or under-estimate is adjusted rather than punished.
What matters is estimating honestly and updating the marketplace if something changes materially mid-year. A large surprise at tax time is almost always a large change nobody reported.
