The 2026 contribution limits let a worker put $24,500 into a 401(k), $7,500 into an IRA and $4,400 (self-only) or $8,750 (family) into a health savings account, according to the IRS [1][3]. Workers age 50 and older can add $8,000 to a 401(k) and $1,100 to an IRA, and workers who are 60 to 63 can add $11,250 instead of $8,000 [1]. Saving the combined maximum of $36,400 a year for 30 years at a 7% annual return would grow to about $3.44 million, of which only $1.09 million would be contributions. This article walks through each limit, the rules around it, and what the arithmetic looks like for a saver who starts early.
What are the 2026 contribution limits for a 401(k), IRA and HSA?
The IRS published the retirement plan figures in Notice 2025-67 on November 13, 2025, and the HSA figures in Revenue Procedure 2025-19 [1][3]. The main numbers are below.
| Account | 2026 limit | 2025 limit | Catch-up (50+) |
|---|---|---|---|
| 401(k), 403(b), most 457 plans, TSP | $24,500 | $23,500 | $8,000 (ages 60 to 63: $11,250) |
| Traditional or Roth IRA (combined) | $7,500 | $7,000 | $1,100 |
| HSA, self-only coverage | $4,400 | n/a | $1,000 at age 55+ |
| HSA, family coverage | $8,750 | n/a | $1,000 at age 55+ |
| SIMPLE IRA | $17,000 | $16,500 | $4,000 (ages 60 to 63: $5,250) |
| Total 401(k) additions incl. employer (415(c)) | $72,000 | $70,000 | n/a |
The $72,000 total defined contribution limit covers employee deferrals, employer matches and any after-tax contributions combined [2]. The annual compensation that a plan may count rose from $350,000 to $360,000, and the highly compensated employee threshold stayed at $160,000 [2].
Income limits that decide who gets the tax break
Roth IRA contributions phase out between $153,000 and $168,000 of modified adjusted gross income for single filers and between $242,000 and $252,000 for married couples filing jointly [1]. The deduction for a traditional IRA phases out between $81,000 and $91,000 for a single filer covered by a workplace plan and between $129,000 and $149,000 for a covered spouse filing jointly [1]. The Saver's Credit income limit is $80,500 for joint filers, $60,375 for heads of household and $40,250 for singles [1].
One new rule matters for higher earners. Starting in 2026, catch-up contributions to a 401(k) must be made as Roth contributions if the participant's prior-year FICA wages from that employer exceeded $150,000 [2]. The catch-up still happens, but the tax deduction on that slice moves from today to retirement.
What $24,500 a year becomes over 30 years
The limits are annual, but their value is cumulative. The table uses a constant contribution and a fixed annual return, compounded once a year. Real results will differ, and no return is guaranteed, but the shape of the numbers is the point.
| Annual contribution | Years | Return | Ending balance | Total contributed |
|---|---|---|---|---|
| $24,500 (401(k) max) | 30 | 7% | $2,314,000 | $735,000 |
| $24,500 (401(k) max) | 30 | 5% | $1,628,000 | $735,000 |
| $24,500 (401(k) max) | 20 | 7% | $1,004,000 | $490,000 |
| $7,500 (IRA max) | 30 | 7% | $708,000 | $225,000 |
| $4,400 (HSA self-only max) | 30 | 7% | $416,000 | $132,000 |
| $36,400 (all three) | 30 | 7% | $3,438,000 | $1,092,000 |
| $8,000 (10% of an $80,000 salary) | 30 | 7% | $756,000 | $240,000 |
Two comparisons stand out. Cutting the horizon from 30 years to 20 years, which is what a ten-year delay does, cuts the ending balance by more than half, from $2.31 million to $1.00 million on the same $24,500 a year. And dropping the assumed return from 7% to 5% removes about $686,000. Time in the market and the return earned matter more than any single year's contribution.
Inflation reduces what those dollars buy. Using a 4% real return instead of 7% nominal, the 401(k) maximum for 30 years ends at about $1.37 million in today's purchasing power. That is still nearly double the $735,000 of contributions.
Why the limits matter even for people who cannot max them
Few workers hit every limit. Vanguard's preview of How America Saves 2026 reports an average 401(k) balance of $167,970 and a median of $44,115 at the end of 2025, with 45% of participants raising their deferral rate during the year, either on their own or through automatic escalation [4]. Roughly 69% of participants were invested in professionally managed allocations such as target-date funds [4]. The gap between the average and the median shows how uneven saving is: a minority of consistent high savers pulls the average up.
For most households the useful benchmark is not the ceiling but the trend. A worker who cannot reach $24,500 can still capture the full employer match, raise the deferral by one percentage point a year, and move to the IRA and HSA limits when cash flow allows. Each of these choices is a personal decision, and the limits simply define how much tax-advantaged space is available.
What the cash yield backdrop means for savers
The Federal Reserve held its target range at 3.50% to 3.75% on June 17, 2026 and said inflation remains elevated relative to its 2% goal [6]. The effective federal funds rate averaged 3.63% in June 2026, according to DataPorium's economic metrics [5]. Cash inside a retirement account earns a positive nominal yield today, but the long-run examples above rely on a diversified mix of stocks and bonds, not cash, to reach a 5% to 7% return.
How the three accounts fit together
- 401(k): largest limit, employer match, payroll automation. Roth catch-ups are mandatory above $150,000 of prior-year wages [2].
- IRA: $7,500 limit with the broadest investment choice. Roth eligibility ends at $168,000 (single) or $252,000 (joint) [1].
- HSA: $4,400 or $8,750 limit, requires a high-deductible health plan with a minimum deductible of $1,700 (self-only) or $3,400 (family) in 2026 [3]. Contributions are deductible, growth is untaxed and qualified medical withdrawals are tax free.
- Order used by many planners: match first, then HSA, then IRA or the rest of the 401(k), because each layer adds a different tax benefit.
The 2026 limits set the ceiling, but the decades of compounding between the first contribution and retirement decide the outcome.
Key takeaways
- 2026 limits: $24,500 for a 401(k), $7,500 for an IRA, $4,400 or $8,750 for an HSA, plus catch-ups of $8,000, $1,100 and $1,000 respectively [1][3].
- Workers aged 60 to 63 get a larger $11,250 401(k) catch-up; workers who earned over $150,000 last year must make 401(k) catch-ups as Roth [1][2].
- Maxing all three accounts for 30 years at 7% builds about $3.44 million from $1.09 million of contributions.
- A ten-year delay cuts the 401(k) result by more than half; the return assumption matters almost as much.
- Average and median 401(k) balances ($167,970 and $44,115) show most savers are far from the limits, so steady increases matter more than the ceiling [4].
Frequently asked questions
What is the 401(k) contribution limit for 2026?
The employee deferral limit is $24,500 in 2026, up from $23,500 in 2025. Workers 50 and older can add $8,000, and workers aged 60 to 63 can add $11,250 instead [1].
Can I contribute to both a 401(k) and an IRA in 2026?
Yes. The limits are separate: $24,500 for the 401(k) and $7,500 for the IRA. The IRA deduction or Roth eligibility may be reduced above the income phase-out ranges [1].
What is the HSA contribution limit for 2026?
The limit is $4,400 for self-only coverage and $8,750 for family coverage, plus $1,000 for account holders 55 and older. The plan must be a high-deductible health plan with at least a $1,700 or $3,400 deductible [3].
How much will maxing a 401(k) for 30 years be worth?
At $24,500 a year and a 7% annual return, the balance would reach about $2.31 million after 30 years. At 5% it would be about $1.63 million. These are illustrations, not forecasts.
