2026 IRS Retirement Contribution Limits: The Complete Guide

Limits & RulesUpdated 2026-01-15

Last verified: 2026-08-18, against IRS Notice 2025-67 (2026 retirement plan limits).

If you save for retirement in 2026, the numbers below are the ones that matter. The IRS sets annual caps on how much you can put into each tax-advantaged account. Hitting the cap is the single biggest lever most savers have. Here is the full list, in plain English.

401(k), 403(b), and most workplace plans

The 415(c) cap is the one most high earners never hear about. It controls how much the "mega backdoor Roth" strategy is worth. A separate article covers that.

Traditional and Roth IRA

457(b) plans for government and certain nonprofit employers

A 457(b) is one of the most underused accounts. Its $24,500 limit stacks on top of your 401(k) or 403(b). If you have access to both, you can defer up to $47,000 of salary in 2026 (before any catch-ups).

SIMPLE IRA

SEP IRA and Solo 401(k) (self-employed)

Health Savings Account (HSA): the only triple-tax-advantaged account

You must be enrolled in a high-deductible health plan (HDHP) to contribute.

Cash balance and defined-benefit plans

These are not subject to the $72,000 415(c) cap. A 55-year-old high-income business owner can often contribute $150,000–$300,000 per year, fully deductible. This is the heaviest deferral tool the tax code offers.

Estate and gift tax (OBBBA permanent)

The One Big Beautiful Bill Act, signed July 4, 2025, made the elevated estate and gift tax exemption permanent. For 2026 the exemption is $15 million per person ($30 million per married couple). Annual gift exclusion: $19,000 per recipient.

What changed in 2026

SECURE 2.0 §603 took effect January 1, 2026: if you earned more than $150,000 in prior-year FICA wages (Box 3 of Form W-2) from the employer sponsoring the plan (IRS Notice 2025-67), your age-50+ catch-up contribution must go into a Roth account (after-tax), not pre-tax. Plan for this now if you are a high-income deferrer over 50.

Frequently Asked Questions

How much can I contribute to my 401(k) in 2026?

The employee deferral limit for 2026 is $24,500, and a participant who is 50 or older may add a catch-up contribution of $8,000, bringing the total to $32,500. Participants aged 60 through 63 fall under the SECURE 2.0 super catch-up, which substitutes $11,250 for the ordinary $8,000 and lifts the total to $35,750. The catch-up is elective in every case.

What is the 415(c) limit for 2026?

The 415(c) limit for 2026 is $72,000. It is the ceiling on everything credited to your account in the plan for the year, and it captures three separate flows: your own elective deferral; your employer's match or profit-sharing contribution; and any after-tax contributions the plan permits. Catch-up contributions sit outside the 415(c) calculation, which is why an older participant can exceed $72,000 in total.

How much can I put in an IRA in 2026?

The 2026 limit is $7,500, or $8,600 for a taxpayer who is 50 or older. The figure applies to all of your Traditional and Roth IRAs in aggregate rather than to each account separately, so opening additional IRAs does not create additional contribution room.

Can I contribute to both a 401(k) and a 457(b) in the same year?

Yes, and this is one of the most underused provisions available to public-sector employees. A 457(b) limit stacks on top of a 401(k) or 403(b) limit rather than sharing with it, so an employee with access to both plans may defer as much as $47,000 of salary in 2026 before any catch-up contribution is considered. The stacking works because a governmental 457(b) is a separate type of arrangement, not a variation on the 401(k).

What are the 2026 Roth IRA income limits?

For single filers the ability to contribute directly phases out between $153,000 and $168,000 of modified adjusted gross income; for married couples filing jointly the range is $242,000 to $252,000. Married taxpayers filing separately face a phaseout of $0 to $10,000, which eliminates the direct contribution for nearly everyone in that filing status.
