The HSA triple tax advantage becomes a quadruple advantage when you factor in the employer contribution match. Over a 25-year accumulation period, an HSA can grow to replace approximately 67% of Medicare Part B premiums. For more on this topic, see Qualified Opportunity Zones.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement. For more on this topic, see Sequence of Returns Risk.
