A proposed increase to Health Savings Account (HSA) contribution limits was cut from the Senate version of the tax bill, setting back efforts to let families better save for medical expenses. The House version of the bill included a provision that would have nearly doubled contribution limits for HSAs, but the Senate opted not to include the measure.

Under current law, the 2025 HSA contribution cap is $4,300 for individuals and $8,550 for families, with an extra $1,000 allowed for people age 55 or older. The House bill would have raised those limits to $8,600 for individuals and $17,100 for families (based on the 2025 limits), bringing them more in line with real healthcare costs and the requirements of high-deductible health plans (HDHPs).

The House Bill wasn’t a perfect solution. It imposed an adjusted gross income (AGI) cap of $75,000 for individuals or $150,000 for married couples. It would have been hard (impossible?) for an individual to even contribute the maximum amount allowed as it would have exceeded 11% of their AGI.

However, the provision was expected to help Americans better prepare for out-of-pocket healthcare costs, especially those enrolled in HDHPs, which require thousands in up-front spending before coverage kicks in.

Why Current HSA Contribution Limits Fall Short

The current HSA structure forces a mismatch between what families are expected to pay out of pocket and what they’re allowed to save in a tax-advantaged account.

To open an HSA, individuals must enroll in an HDHP, which in 2025 can carry a deductible as high as $1,650 for individuals and $3,300 for families. Out-of-pocket maximums can reach $8,300 for individuals and $16,600 for families. In many cases, the allowed contribution doesn’t even match the potential yearly out-of-pocket costs.

So, you could face a medial bill of $8,000, but only be allowed to contribute $4,300… it just doesn’t make sense.

As a result, families facing major health events may end up depleting their HSA balances quickly and still have significant uncovered expenses. Raising the contribution caps would let account holders better prepare for medical costs while maintaining the tax advantages HSAs offer.

Marriage Penalty Issues

Another issue is the so-called “marriage penalty” built into current HSA contribution limits. 

Two unmarried individuals with self-only coverage can each contribute up to $4,300 in 2025, for a combined $8,600.

But if they marry and switch to family coverage, their combined cap becomes $8,550, $50 lower. Older couples who have a catch-up contribution also face an issue. If it’s two unmarried adults with their own self-only coverage, they can each make a $1,000 catch-up contribution. However, if they marry, only one spouse can make a $1,000 catch-up contribution. 

The HSA is one of the few areas that still has a marriage penalty, which runs counter to the GOP’s focus on family.

What’s Next?

With the Senate’s version of the bill (PDF File) omitting the HSA expansion, any changes would now need to be negotiated in conference. The removal may indicate lack of consensus or concern about budget implications.

Proponents of HSA reform argue that without higher limits, the accounts will remain mismatched to the cost realities of our current healthcare system. The average American household with an HDHP can’t meaningfully shield itself from out-of-pocket costs under the current caps.

While HSAs remain a popular tool among higher-income households, many Americans struggle to contribute anything beyond minimal amounts. Raising the limits wouldn’t solve affordability issues for everyone, but it would give savers a better chance at planning for medical costs over time.

As healthcare costs continue to rise, pressure is likely to grow for Congress to revisit HSA contribution rules, especially as more Americans rely on HDHPs as their only health coverage option.
