What is the 'triple tax advantage' that makes a Health Savings Account (HSA) so valuable?

An HSA offers three distinct tax benefits that no other savings vehicle provides simultaneously. Contributions are made with pre-tax dollars (or are tax-deductible if made after tax), the money grows tax-free through interest or investments, and withdrawals used for qualified medical expenses are completely tax-free. For 2025, contribution limits are $4,300 for individual coverage and $8,550 for family coverage, with an additional $1,000 catch-up contribution allowed for those aged 55 and older.
