Intelligence Brief

Today’s free issue covers the Medicare Part B keep-or-drop decision at $202.90 a month, and this issue covers the account that sits on the other side of that decision. With US healthcare inflation still compounding and the dollar firm (DXY around 101, roughly 4 percent yields on USD cash), the HSA is the one US tax shelter whose value survives a move abroad intact. Most expats either forget theirs or accidentally poison it in their final US working year.

Almost every US tax-advantaged account gets worse when you leave the country. Retirement accounts stay locked behind age rules. FEIE elections interact badly with IRA contribution eligibility. State-tax advantages evaporate with domicile. The Health Savings Account is the exception, and almost nobody plans around it. Money in an HSA went in deductible, grows untaxed, and comes out tax-free for qualified medical expenses, and here is the part that matters for this audience: the IRS does not care where on the planet the medical care happens. A specialist visit in Panama City, a dental crown in Chiang Mai, a hospital stay in Lisbon, all of it is reimbursable from your HSA at zero tax, exactly as if it happened in Ohio. For an expat household, an HSA built during US working years becomes a permanent, portable, tax-free healthcare fund denominated in dollars. This issue covers the mechanism, the expat-specific advantage, the setup sequence, and the one mistake that generates IRS penalties in your final American year.

Section 1 - The mechanism

An HSA is the only account in the US code with a triple tax advantage. Contributions are deductible (or pre-tax through payroll), growth is untaxed, and withdrawals are tax-free when they reimburse qualified medical expenses. For 2026, contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, plus a $1,000 catch-up from age 55.
