Each fall the IRS releases new contribution limits for tax-advantaged retirement accounts, and for 2026 the figures stepped up again with inflation. Knowing these numbers is the difference between leaving free tax savings on the table and squeezing every dollar of growth out of your 401(k), IRA, and Roth accounts. This guide lays out the estimated 2026 limits, the catch-up rules that reward older savers, and the income phase-outs that quietly disqualify high earners from a Roth IRA. As you plan your contributions, our retirement calculator can show how maxing out each account changes your long-term balance.
2026 401(k) contribution limit
For 2026 the employee elective deferral limit for a 401(k), 403(b), and most 457 plans is approximately $24,500, up from $23,500 in 2025. That is the amount you personally can defer from your paycheck; it does not include your employer's match. This figure is an inflation-adjusted estimate based on IRS methodology — confirm the final number on IRS.gov before you max out.
The total combined limit (your contributions plus employer match plus any after-tax contributions) is much higher — around $72,000 for 2026, or about $80,000 once catch-up amounts are included. That higher ceiling is what makes the mega backdoor Roth strategy possible for plans that allow after-tax contributions.
2026 401(k) catch-up contributions
- Age 50 and older: an extra catch-up of about $8,000, bringing the total to roughly $32,500.
- Ages 60 to 63: a higher "super catch-up" of about $11,250 under the SECURE 2.0 rules, for a total near $35,750.
One important SECURE 2.0 change phasing in: higher earners (those above a wage threshold) are required to make catch-up contributions on a Roth (after-tax) basis rather than pre-tax. Check with your plan administrator on how your employer is implementing this.
2026 IRA contribution limit
The 2026 contribution limit for traditional and Roth IRAs combined is approximately $7,500, up from $7,000 in 2025. If you are 50 or older, you can add a catch-up of roughly $1,100, for a total near $8,600. This limit is shared across all your IRAs — you cannot put $7,500 in a traditional IRA and another $7,500 in a Roth IRA in the same year.
Because the IRA limit is modest, prioritizing it well matters. Many savers use a Roth IRA for tax-free growth and the IRA's wide investment menu, which is usually broader than a 401(k) lineup. To compare how different fund choices grow over decades, run scenarios in our investment calculator.
Roth IRA income phase-outs for 2026
Unlike a 401(k), a Roth IRA has income limits. If your modified adjusted gross income (MAGI) is too high, your contribution is reduced or eliminated. The estimated 2026 phase-out ranges are:
- Single / head of household: phase-out roughly $153,000 to $168,000.
- Married filing jointly: phase-out roughly $242,000 to $252,000.
- Married filing separately: phase-out $0 to $10,000.
If you earn above the top of your range, you cannot contribute directly to a Roth IRA — but the backdoor Roth (contributing to a traditional IRA and converting) remains a legal workaround for many high earners.
Traditional IRA deduction limits
Anyone with earned income can contribute to a traditional IRA, but whether the contribution is tax-deductible depends on your income and whether you (or a spouse) are covered by a workplace retirement plan. If you are covered by a 401(k), the deduction phases out at lower income levels; if neither spouse is covered, the full deduction is generally available regardless of income. The phase-out ranges are also inflation-adjusted for 2026.
How to prioritize your 2026 contributions
With limited dollars, order of operations matters. A widely used sequence:
- 1. Contribute to your 401(k) up to the full employer match — that match is an instant return you cannot beat.
- 2. Max out a Roth IRA (or backdoor Roth) for tax-free growth and flexible withdrawals.
- 3. Return to the 401(k) and work toward the full $24,500 limit.
- 4. If you have an HSA-eligible health plan, fund the HSA — it is triple tax-advantaged.
- 5. Consider after-tax 401(k) contributions for a mega backdoor Roth if your plan allows it.
The power of maxing out comes from compounding. A $24,500 annual 401(k) contribution growing at 7% becomes well over $1 million in 20 years. See exactly how that snowball builds in our compound interest calculator.
A quick note for Canadian readers
If you are in Canada, the 401(k) and IRA don't apply, but the equivalents are the RRSP and TFSA. For 2026 the TFSA limit is expected to be $7,000 and RRSP room is 18% of prior-year earned income up to an annual maximum that also rises each year. The same priority logic applies — capture any employer RRSP match first, then balance RRSP and TFSA based on your tax bracket.

Frequently Asked Questions
What is the 401(k) contribution limit for 2026?
For 2026 the employee 401(k) deferral limit is approximately $24,500. Workers age 50 and older can add a catch-up of about $8,000, and those aged 60 to 63 qualify for a higher super catch-up near $11,250. These are estimates pending the final IRS announcement; confirm on IRS.gov before maxing out.
What is the IRA contribution limit for 2026?
The 2026 IRA contribution limit is about $7,500 across all your traditional and Roth IRAs combined, with an additional catch-up of roughly $1,100 if you are 50 or older. Roth IRA eligibility phases out at higher incomes, and traditional IRA deductibility can be limited if you have a workplace plan.
Can I contribute to both a 401(k) and an IRA in 2026?
Yes. The 401(k) and IRA have separate limits, so you can fund both in the same year. Many savers capture the full 401(k) employer match, then fund an IRA, then return to the 401(k). Just watch the Roth IRA income phase-outs and traditional IRA deduction rules if you are also covered by a workplace plan.
What happens if I contribute too much to my 401(k) or IRA?
Excess contributions are subject to a 6% excise tax each year they remain in the account. If you catch the mistake, withdraw the excess plus any earnings before the tax-filing deadline to avoid the penalty. For 401(k) over-deferrals, ask your plan administrator to return the excess promptly.
