Who it applies to
Employees who make elective deferrals out of their pay into an employer-sponsored retirement plan, and the employers and plan administrators who apply the limitation for the 2026 plan year. The notice states the figure under section 402(g) for the elective deferrals described in that section, and notes that they include elective deferrals made to the Thrift Savings Plan. The $8,000 catch-up figure applies to participants aged 50 or over.
What changed this year, and why
Notice 2025-67 increases the limitation under section 402(g) on the exclusion for elective deferrals from $23,500 to $24,500 for 2026. The catch-up contribution limitation under section 414(v) that generally applies to individuals aged 50 or over increases from $7,500 to $8,000. The notice states the same $24,500 figure for the separate limitation on deferrals under section 457, which it also raises from $23,500.
Common questions
- How much can I defer into my employer retirement plan in 2026?
- Notice 2025-67 states the limitation under section 402(g) on the exclusion for elective deferrals as $24,500 for 2026. That figure caps what you elect to defer out of your own pay. If you are aged 50 or over, the notice states a further catch-up limitation under section 414(v) of $8,000, published as a separate amount rather than folded into the deferral figure.
- What changed from the 2025 limits?
- Both figures on this page moved. Notice 2025-67 states the section 402(g) elective deferral limitation as increased from $23,500 to $24,500, and the section 414(v) catch-up limitation for individuals aged 50 or over as increased from $7,500 to $8,000. The notice writes each change as a movement between two stated amounts rather than as a difference.
- What is the catch-up contribution for workers aged 50 and over in 2026?
- It is $8,000. Notice 2025-67 states the catch-up limitation under section 414(v) for an applicable employer plan, which generally applies to individuals aged 50 or over, as increased from $7,500 to that amount. It is set out in its own sentence, separate from the $24,500 elective deferral limitation, and it applies to plans other than the SIMPLE arrangements the notice addresses on their own.
- Does the deferral limit include employer contributions?
- No. Notice 2025-67 states the $24,500 figure as the limitation under section 402(g) on the exclusion for elective deferrals, which covers what you elect to defer. The overall limitation for defined contribution plans sits under section 415(c) and the notice increases that separately, in its own sentence with its own amount. They are published as two distinct items.
- Does the same limit apply to a governmental deferred compensation plan or the Thrift Savings Plan?
- Notice 2025-67 states that the elective deferrals covered by the section 402(g) limitation include elective deferrals made to the Thrift Savings Plan. It also increases the limitation on deferrals under section 457, concerning deferred compensation plans of state and local governments and tax-exempt organizations, from $23,500 to $24,500 for 2026. The notice publishes those as two limitations carrying the same figure.
- Is there an income limit on how much I can defer in 2026?
- Notice 2025-67 states the section 402(g) elective deferral limitation as a single amount, with no income-based reduction attached. The income-based figures elsewhere in the notice belong to other provisions: adjusted gross income limitations for the retirement savings contributions credit under section 25B, and phase-out ranges for deducting a traditional IRA contribution under section 219 and for contributing to a Roth IRA under section 408A.
- Is there a larger catch-up contribution for ages 60 through 63?
- Notice 2025-67 states a separate and higher catch-up limitation under section 414(v) for individuals who attain ages 60 through 63 during 2026. That amount is verified on the catch-up contribution page for this year rather than here, because the two figures verified for this page are the section 402(g) elective deferral limitation and the section 414(v) catch-up limitation for individuals aged 50 or over.
- Where does the 2026 contribution limit come from?
- Notice 2025-67, the annual IRS notice of amounts relating to retirement plans and IRAs as adjusted for changes in cost-of-living. Section 415 of the Internal Revenue Code provides for limitations on benefits and contributions under qualified retirement plans, and section 415(d) requires the Secretary of the Treasury to adjust them annually for cost-of-living increases. The deferral and catch-up figures are adjusted at the same time and in the same manner as the limitation of section 415(b), after rounding rules are applied.
Every amount on this page is a published figure rather than yours. The 401(k) contribution planner takes the number you enter and works it out against them, showing which published figure it used.
What the limit counts, and the tax it does not save
An elective deferral is money you choose to have your employer pay directly into a qualified retirement plan instead of receiving as regular wages. It applies to arrangements such as cash or deferred arrangements, the federal Thrift Savings Plan, tax-sheltered annuities, salary reduction simplified employee pensions, SIMPLE plans, and governmental deferred compensation plans. The key tax feature is that a traditional elective deferral is not counted as wages subject to federal income tax at the moment it goes into the plan, so it lowers the income tax you owe for that year. However, the amount is still subject to social security and Medicare taxes, so your payroll tax base is not reduced by what you defer. A separate category called a designated Roth contribution works differently: it is included in your taxable income up front. Both kinds count toward the same annual limit on how much you can defer across all of your plans in a given year. For 2026, that base elective deferral limit is $24,500. You are responsible for tracking the total you put in across every plan you participate in, even though your employer applies the limit on each plan individually.
An elective deferral, other than a designated Roth contribution (discussed later), isn’t included in wages subject to income tax at the time contributed. However, it’s inclu- ded in wages subject to social security and Medicare taxes.

One limit across every plan you defer into
The IRS does not give you a separate deferral cap for each plan you happen to be covered by. Instead, it sets one overall annual limit that applies to the total of all your elective deferrals across every qualifying plan taken together. That means if you work two jobs in the same year and both employers let you defer into a qualified retirement plan, the dollar cap is shared between the two accounts. It is your responsibility, not your employer's, to watch the combined total. Employers and plan administrators apply the correct annual limit when they process contributions, but they generally cannot see what you are deferring into a different employer's plan. If the combined deferrals exceed the overall limit, you have excess deferrals that must be corrected, typically by requesting a distribution of the excess from one of the plans by April 15 of the following year. The limit does not depend on how many plans you participate in or how much you earn. For 2026, the overall limit on elective deferrals is $24,500.
Your employer or plan administrator should apply the proper annual limit when figuring your plan contributions. However, you’re responsible for monitoring the total you defer to ensure that the deferrals aren’t more than the overall limit.
Publication 525 (2025), Taxable and Nontaxable Income (IRS)
The catch-up once you are old enough for it
Once you reach age 50, the tax code allows you to defer more than the regular elective deferral limit. These extra amounts are called catch-up contributions, and they are available only if you are age 50 or older by the end of the tax year. The catch-up is an addition on top of the regular limit, not a replacement for it. Catch-up contributions apply to employer-sponsored retirement plans including cash or deferred arrangements, tax-sheltered annuities, the federal Thrift Savings Plan, salary reduction simplified employee pensions, and governmental deferred compensation plans. For 2026, the catch-up amount available to participants age 50 or older is $8,000, which is added to the regular $24,500 elective deferral limit. An eligible participant can therefore defer the full regular limit plus the catch-up amount on top of it in the same year. The catch-up is intended to help workers who are closer to retirement build up savings more quickly. If you participate in more than one plan, catch-up contributions can generally only be made to one plan unless the plans coordinate otherwise.
You may be allowed catch-up contributions (additional elective de- ferrals) if you’re age 50 or older by the end of your tax year.
Publication 525 (2025), Taxable and Nontaxable Income (IRS)
The larger catch-up in the year you turn 60 through 63
A participant who attains age 60, 61, 62 or 63 during the year is allowed a larger catch-up than other catch-up-eligible participants get. For 2026 that larger amount is $11,250 rather than $8,000, and it sits on top of the $24,500 elective deferral limit exactly as the smaller one does. The band is defined by the age reached during the year rather than one held throughout it, so someone who attains 60 in December is inside it for that whole year. Someone past the band is back to the ordinary amount: the larger figure is stated for those ages and no others. A plan is not required to offer it at all, and where the plan does not, the ordinary catch-up applies whatever the participant's age - which is why what payroll will actually take is the plan's answer and not only the notice's.
The catch-up limit is $11,250 if you are age 60, 61, 62, or 63 in 2025.
Publication 525 (2025), Taxable and Nontaxable Income (IRS)
What happens if you defer more than the limit
When your total elective deferrals for the year exceed the annual limit, the excess is called an excess deferral. You must notify your plan by the date the plan requires. If the plan allows it, the excess amount will be distributed back to you. If you participate in more than one plan, you can have the excess paid out from any plan that permits these distributions, but you must notify each plan by its required date about the amount to be paid from that particular plan. The plan must then distribute the excess, together with any income earned on that amount, by April 15 of the following year. The excess deferral must be included in your income for the year it was contributed, so you add the amount to earned income on your tax return. If you fail to take out the excess by the deadline, you face a double tax: the excess is taxed once when contributed and again when eventually distributed, unless the excess was a designated Roth contribution, in which case it was already included in income.
If your deferrals exceed the limit, you must notify your plan by the date re- quired by the plan. If the plan permits, the ex- cess amount will be distributed to you.

Roth deferrals count against the same limit
Employers that sponsor certain qualified retirement plans may offer a designated Roth option within the plan. Under such a program, you can elect to have some or all of your elective deferrals treated as after-tax Roth contributions rather than pre-tax contributions. The important point is that designated Roth contributions are still elective deferrals, and they still count against the same annual limit that applies to traditional pre-tax deferrals. For 2026, that limit is $24,500 in total across both traditional and Roth deferrals combined. The difference is purely in the timing of taxation: a designated Roth contribution is included in your wages and taxed in the year it is made, whereas a traditional elective deferral is excluded from income tax when contributed but taxed when distributed later. The plan must maintain separate accounts and record-keeping for the designated Roth contributions. Qualified distributions from a Roth account are then tax-free, provided the distribution meets the required holding period.
Designated Roth contributions are treated as elective deferrals, except that they’re included in income.
