Americans who hold a high-deductible health plan and turn 55 gain the right to contribute an extra $1,000 per year to a health savings account, a fixed dollar amount that has not changed since HSAs were created more than two decades ago. The IRS confirmed in Rev. Proc. 2025-19 that the catch-up contribution amount remains at $1,000 for 2026, even as the base contribution limits rise with inflation. That growing gap between static catch-up dollars and inflation-adjusted caps is quietly shrinking the relative value of the extra room available to older savers.
Why the fixed $1,000 catch-up loses ground each year
The tension is straightforward. Base HSA contribution limits are recalculated annually using a cost-of-living formula spelled out in the tax code. The catch-up amount is not. Congress wrote a flat $1,000 into Section 223(b)(3) of the Internal Revenue Code, and no inflation adjustment mechanism was attached. Each time the IRS publishes new annual limits through a revenue procedure, the base cap climbs while the catch-up stays put.
For a worker with self-only coverage who turns 55, the $1,000 add-on represented a larger share of total allowable contributions when HSAs launched. As base limits have risen year after year, that share has contracted. The practical effect: the catch-up’s purchasing power erodes against medical costs that tend to outpace general inflation, and the tax benefit it delivers becomes proportionally smaller relative to the growing base limit. No IRS or Treasury official has publicly signaled plans to index the catch-up amount, and the statutory text offers no mechanism to do so without new legislation.
Statutory and regulatory evidence behind the $1,000 figure
The $1,000 catch-up traces back to the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, which added HSAs to the tax code. Early IRS interpretive guidance in Notice 2004-2 explained how catch-up contributions work for individuals ages 55 through 65, including timing rules and eligibility when spouses each have an HSA. Follow-up questions were addressed in Notice 2004-50, which referenced the catch-up provision under Section 223(b)(3) and clarified how the additional amount interacts with contribution limits for family coverage.
A Treasury press release from the program’s rollout confirmed that catch-up contributions for those ages 55 to 65 increase to $1,000 annually, and IRS Publication 969 has consistently stated that an additional contribution amount of $1,000 is allowed for individuals age 55 or older. The same $1,000 figure appears in federal employer comparability regulations, where it factors into how companies calculate equal HSA contributions across employee groups and determines whether an employer’s formula satisfies nondiscrimination rules.
Rev. Proc. 2025-19, published in Internal Revenue Bulletin 2025-21, sets the 2026 inflation-adjusted HSA and high-deductible health plan thresholds under IRC Section 223. The catch-up contribution amount listed in that procedure is $1,000, unchanged from every prior year since the provision reached its statutory ceiling. Because the revenue procedure simply applies the statute, the IRS has no discretion to increase the catch-up amount beyond what Congress has written into law.
Open questions about the unindexed HSA catch-up
Several policy questions flow from the decision to leave the HSA catch-up unindexed. One is whether Congress intended the $1,000 figure to be a permanent benchmark or a temporary approximation of what older workers might reasonably need. When HSAs were introduced, lawmakers also set catch-up contributions for retirement accounts and later chose to index or periodically raise many of those limits. HSAs, by contrast, were given a static catch-up even though they are often framed as a key tool for retirement health-care planning.
Another question is whether the shrinking relative size of the catch-up undermines the original goal of encouraging older Americans to save more for medical expenses. As base limits grow, the incremental incentive for someone turning 55 becomes relatively modest. For higher-income households, the flat $1,000 may not materially change saving behavior. For middle-income workers facing rising premiums and out-of-pocket costs, the lack of indexing means the extra room does less each year to offset future expenses.
There are also administrative and equity considerations. Because the catch-up is a simple round number, it is easy for employers and account administrators to communicate and program into payroll systems. Indexing the amount could introduce complexity, with a new figure each year layered on top of the already-changing base limits. At the same time, leaving the amount frozen may disproportionately affect workers who rely most heavily on tax-preferred savings to manage health-care shocks late in their careers.
Any change to the catch-up structure would require congressional action. Stakeholders who want to see the $1,000 amount indexed or increased have limited formal channels to press their case with the IRS, which is bound by the statute. Taxpayers and industry groups can, however, submit comments and raise concerns through the agency’s online feedback system or in response to proposed regulations that touch on HSAs more broadly.
For now, older HSA participants must plan around a catch-up contribution that is fixed in nominal terms but shrinking in real value. As long as the $1,000 figure remains unindexed, each new round of inflation adjustments to the base limits will widen the gap between what the law allows younger and older savers to add on a percentage basis, even if the dollar difference never changes.
