The 2027 HSA contribution limits are now official. The IRS set the self-only limit at $4,500 and the family limit at $9,000 in Revenue Procedure 2026-24, released in mid-2026. If you found this page looking for a "projection," the good news is you no longer have to guess. Early forecasts from benefits firms like Mercer and the analyst known as "Mr. HSA" landed right on target, and the IRS confirmed the numbers well ahead of the 2027 plan year.
This guide lays out every 2027 figure, compares it to 2026, explains how the IRS calculates these amounts, and shows what the changes mean for how much you can set aside tax-free.
2027 HSA Contribution Limits at a Glance
Health Savings Account contribution limits rise almost every year because they are indexed to inflation. Here is what the IRS confirmed for the 2027 tax year.
| Coverage Type | 2027 Limit | 2026 Limit | Increase |
|---|
| Self-only coverage | $4,500 | $4,400 | +$100 |
| Family coverage | $9,000 | $8,750 | +$250 |
| Catch-up (age 55+) | $1,000 | $1,000 | No change |
The self-only limit went up 2.27 percent, and the family limit went up about 2.86 percent. Both increases are smaller in percentage terms than recent years because inflation cooled compared to the 2022 to 2024 stretch.
The $1,000 catch-up contribution for account holders age 55 and older stayed flat. That amount is fixed by law rather than adjusted for inflation, so it has been $1,000 since 2009 and will not move until Congress changes the statute.
What the Projections Predicted
Before the IRS released official numbers, benefits consultants publish annual HSA projections based on the same inflation formula the IRS uses. For 2027, the major forecasts converged early:
- Mercer projected $4,500 self-only and $9,000 family.
- The widely followed "Mr. HSA" analysis finalized the same figures.
- BenefitsPro and 401k Specialist reported the same 2.27 percent individual increase.
All of these projections matched the final IRS numbers exactly. That is not luck. The inflation adjustment uses a defined formula, so anyone who applies the published price index correctly can usually predict the figures within a dollar or two months before the official announcement.
How the IRS Calculates HSA Limits
HSA and High Deductible Health Plan (HDHP) limits are adjusted each year using the Chained Consumer Price Index for All Urban Consumers, known as C-CPI-U. This is a specific measure of inflation the IRS applies to a base amount, then rounds to the nearest $50.
A few things make these numbers predictable:
- The index is public. The Bureau of Labor Statistics releases C-CPI-U data monthly, so analysts can run the math before the IRS does.
- The measurement period ends in the spring. The IRS typically uses the 12-month period ending in March, which is why official announcements usually come in April or May.
- Rounding smooths things out. Because amounts round to the nearest $50, small inflation differences do not change the result, which is why projections tend to be accurate.
The catch-up contribution is the exception. It is written into the tax code as a flat $1,000 with no inflation adjustment, so it never changes through this process.
2027 HDHP Requirements
To contribute to an HSA, you must be enrolled in a qualifying High Deductible Health Plan. The IRS sets minimum deductibles and maximum out-of-pocket limits that a plan must meet to count as an HDHP. These also changed for 2027.
| HDHP Rule | 2027 | 2026 | Change |
|---|
| Minimum deductible (self-only) | $1,750 | $1,700 | +$50 |
| Minimum deductible (family) | $3,500 | $3,400 | +$100 |
| Maximum out-of-pocket (self-only) | $8,700 | $8,500 | +$200 |
| Maximum out-of-pocket (family) | $17,400 | $17,000 | +$400 |
Your plan must have a deductible at or above the minimum and cap your out-of-pocket spending at or below the maximum. If your health plan falls outside these limits in 2027, it is not HSA-eligible, and you cannot make HSA contributions for the months you are enrolled in it.
Note the difference between the minimum deductible and the maximum out-of-pocket amounts. The deductible is the floor a plan needs to qualify. The out-of-pocket maximum is the ceiling on what you pay in a year through deductibles, copays, and coinsurance, not counting premiums.
What the 2027 Increase Means for You
The higher limits give you a bit more room to save with a triple tax advantage: contributions reduce your taxable income, the money grows tax-free, and withdrawals for qualified medical expenses are tax-free.
Here is how the new headroom breaks down:
- Self-only account holders can put away $100 more in 2027 than in 2026, for a total of $4,500.
- Families get $250 more, reaching $9,000.
- Anyone 55 or older can still add the $1,000 catch-up on top, so a self-only saver at that age can contribute $5,500 and a family saver can contribute $10,000.
- Married couples both 55 or older can each add a $1,000 catch-up, but the second catch-up must go into a separate HSA in the other spouse's name.
If you contribute through payroll, your employer's system will usually update automatically for the new plan year, but it is worth confirming your election so you capture the full amount.
HSA Contribution Rules to Keep in Mind
The dollar limits are only part of the picture. A few rules affect how much you can actually contribute in 2027:
- You must be HSA-eligible. That means being covered by a qualifying HDHP, having no other disqualifying coverage, not being enrolled in Medicare, and not being claimed as a dependent on someone else's tax return.
- Medicare ends eligibility. Once you enroll in any part of Medicare, you can no longer contribute to an HSA. If you sign up mid-year, your limit is prorated for the months you were eligible.
- The deadline is tax day. You can make 2027 contributions up until the federal tax filing deadline in April 2028, not just through December 31, 2027.
- Employer contributions count. Any money your employer puts into your HSA counts toward the annual limit. If your employer contributes $1,000 to a family account, you can add up to $8,000 yourself.
- Over-contributing has a cost. Excess contributions are subject to a 6 percent excise tax each year they remain in the account, so withdraw any overage before the deadline.
How 2027 Compares to Recent Years
HSA limits have climbed steadily as inflation pushed the indexed amounts higher. The self-only limit has moved from $3,650 in 2022 to $4,500 in 2027, and the family limit has gone from $7,300 to $9,000 over the same stretch.
| Year | Self-only | Family |
|---|
| 2025 | $4,300 | $8,550 |
| 2026 | $4,400 | $8,750 |
| 2027 | $4,500 | $9,000 |
The 2027 increases are modest compared to the larger jumps in 2024 and 2025, reflecting the slowdown in inflation. If inflation stays low, future increases are likely to stay in the $50 to $250 range as well.
Frequently Asked Questions
What is the 2027 HSA contribution limit?
For 2027, you can contribute up to $4,500 with self-only HDHP coverage and up to $9,000 with family coverage. Account holders age 55 and older can add a $1,000 catch-up contribution on top of those amounts.
Are the 2027 HSA limits official or still a projection?
They are official. The IRS confirmed the 2027 figures in Revenue Procedure 2026-24, released in 2026. Earlier projections from firms like Mercer matched the final numbers exactly.
Did the HSA catch-up contribution change for 2027?
No. The catch-up contribution for account holders 55 and older stays at $1,000. It is set by statute and does not adjust for inflation, so it has been $1,000 since 2009.
What are the 2027 HDHP requirements?
A qualifying plan for 2027 must have a minimum deductible of $1,750 for self-only coverage or $3,500 for family coverage. The maximum out-of-pocket cannot exceed $8,700 for self-only or $17,400 for family coverage.
When can I start making 2027 HSA contributions?
You can contribute for the 2027 tax year at any point during 2027 and up until the federal tax filing deadline in April 2028. Contributions made in early 2028 can be designated for either 2027 or 2028.
How does the IRS decide the HSA limits each year?
The IRS adjusts HSA and HDHP limits using the Chained Consumer Price Index for All Urban Consumers (C-CPI-U), applied to a base amount and rounded to the nearest $50. Because the formula and inflation data are public, analysts can project the numbers accurately before the IRS announces them.
Can both spouses make catch-up contributions?
Yes, if both spouses are 55 or older. Each spouse can add a $1,000 catch-up, but the second catch-up must be deposited into a separate HSA held in that spouse's name.
