2027 HSA Contribution Limits Announced — What Cross-Border Workers Should Know

Summary

Revenue Procedure 2026-24 has been released, setting the inflation-adjusted HSA contribution limits for 2027. The adjusted figures include the maximum annual contribution for self-only and family coverage, as well as the minimum deductible and maximum out-of-pocket thresholds for high-deductible health plans (HDHPs). For Canadian residents who hold US HSAs — whether from a prior US job, ongoing cross-border employment, or self-employment with US-source income — these limits are essential for planning. HSAs offer a triple tax advantage: pre-tax contributions, tax-free growth, and tax-free distributions for qualified medical expenses. Contributions exceeding the inflation-adjusted limit are subject to a 6% excise tax each year until corrected.

Our Take

For Canada-US cross-border taxpayers, HSAs remain a uniquely efficient retirement healthcare vehicle — but only if the contribution limits are strictly observed. While Canada does not recognize the HSA's special tax status, contributions reduce US adjusted gross income (AGI), and distributions for qualified expenses come out US tax-free. Two practical pitfalls: (1) contributions must be made by the US tax filing deadline (not the calendar year end), and (2) even unintentional over-contributions trigger a 6% excise tax. Additionally, CRA may treat HSA growth as passive investment income for Canadian tax purposes, creating a potential US-Canada characterization mismatch. Cross-border filers should coordinate HSA planning with their overall US-Canada strategy.
