Family coverage long hold
2026 family plan with a 20-year horizon
Useful when you want to show the combined value of the upfront deduction and tax-free compounding over a long medical-expense runway.
Result: The long-run gap grows meaningfully because the taxable comparison starts with fewer after-tax dollars and then pays tax on the gain again at exit.
Age-55 self-only saver
Catch-up eligible with lower annual contributions
A common late-career planning check when the HSA is doubling as a medical reserve and a stealth retirement bucket.
Result: The age-55 catch-up keeps a moderate contribution plan inside the annual cap while still creating a real tax delta versus taxable investing.
