The IRS has announced that the amount of tax-favored funds that you can sock away for retirement is increasing. In 2025, the amount most individuals can contribute to their 401(k) plans will tick up to $23,500—it was $23,000 for 2024.

The announcement is tied to cost‑of‑living adjustments for pension plans and other retirement-related items for tax year 2025 (those adjustments are required by law).

Here’s a look at some of the most common plans and what will be different next year:

401(k) and Similar Plans

As noted, the amount individuals can contribute to their 401(k) plans is $23,500—that limit applies to employee contributions made to 401(k) plans and similar plans maintained by non-profit and government employers—403(b) plans, most 457 plans and the federal government’s Thrift Savings Plan for workers.

The catch-up contribution limit that generally applies for employees aged 50 and over who participate in most 401(k), 403(b), governmental 457 plans, and the federal government’s Thrift Savings Plan remains $7,500 for 2025 (the same as in 2024). That means that participants in most 401(k), 403(b), governmental 457 plans and the federal government’s Thrift Savings Plan who are 50 and older generally can contribute up to $31,000 each year, starting in 2025.

In good news for younger seniors, SECURE 2.0 allows for a higher catch-up contribution limit for employees aged 60, 61, 62 and 63 who participate in these plans. For 2025, this higher catch-up contribution limit is $11,250 (compared to $7,500 for everyone else).

Typically, these are pre-tax contributions made to retirement plans by workers. You’re likely already familiar with how it works at the onset—you tick a box on a benefits form that allows you to set aside part of your earnings for retirement. From a tax standpoint, the benefit is two-fold: earnings don't count towards your current year income (which reduces your potential tax bill) and it grows tax-deferred. When you reach retirement age, withdrawals are taxable as you take the money out—certain exceptions may apply, including money transferred directly to charity.

IRA Plans

There’s no boost in the limit on annual contributions to an IRA—that remains $7,000. The limit applies to the total amount contributed to your traditional and Roth IRAs. IRA plans also allow catch‑up contributions for individuals aged 50 and over—that remains $1,000 for 2025, for a total of $8,000 for workers age 50 and above.

With a traditional IRA, contributions are tax-advantaged. If you meet the criteria—that’s where these limits come into play—contributions will be tax-deductible, resulting in a lower tax bill. As with a 401(k) plan, the earnings inside an IRA grow tax-deferred and are subject to tax when you make withdrawals.

In addition to the contribution limits, phase-outs apply. What this means is that if during the year, you or your spouse was covered by a retirement plan at work, your tax deduction may be reduced, or phased out, until it is eliminated, depending on your filing status and income. Here are the phase‑out ranges for 2025:

For single taxpayers covered by a workplace retirement plan, the phase-out range is increased to between $79,000 and $89,000, up from between $77,000 and $87,000 in 2024.

For married couples filing jointly, if the spouse making the IRA contribution is covered by a workplace retirement plan, the phase-out range is increased to between $126,000 and $146,000, up from between $123,000 and $143,000 in 2024.

For an individual contributing to an IRA who is not covered by a workplace retirement plan and is married to someone who is covered, the phase-out range is increased to between $236,000 and $246,000, up from between $230,000 and $240,000 in 2024.

For a married individual filing a separate return who is covered by a workplace retirement plan, the phase-out range is not subject to an annual cost-of-living adjustment and remains between $0 and $10,000 (those numbers do not change because they not subject to an annual cost-of-living adjustment).

Importantly, if neither you nor your spouse is covered by a retirement plan at work, the phase-outs of the deduction do not apply.

Roth IRA Plans

When it comes to tax, Roth IRAs are treated much differently than traditional IRAs. Unlike a traditional IRA, contributions to a Roth IRA are not deductible when made. The upside? Qualified withdrawals are typically tax-free, assuming that you meet the criteria, including that you've owned your account for five years and you have reached age 59½ or more (some exceptions apply).

As noted above, the limit on annual contributions to an IRA remains $7,000 in 2025—that limit applies to the total amount contributed to your traditional and Roth IRAs.

Income phase-outs also apply to Roth IRAs. For 2025, those numbers have increased to between $150,000 and $165,000 for singles and heads of household, up from between $146,000 and $161,000 in 2024. For married couples filing jointly, the income phase-out range is increased to between $236,000 and $246,000, up from between $230,000 and $240,000 in 2024. And, as with traditional IRAs, the phase-out range for a married individual filing a separate return who makes contributions to a Roth IRA is not subject to an annual cost-of-living adjustment and remains between $0 and $10,000.

SIMPLE Retirement Accounts

A SIMPLE IRA plan—SIMPLE stands for Savings Incentive Match Plan for Employees—makes it easy for small businesses who are not currently sponsoring a retirement plan to contribute to IRAs. Contributions to SIMPLE IRA accounts are always 100% vested, or owned, by the employee.

The amount that individuals can contribute to their SIMPLE retirement accounts will increase to $16,500 in 2025, up from $16,000 in 2024. The catch-up contribution limit for employees 50 and over who participate in SIMPLE IRA plans remains an additional $3,500 for 2025, bringing total potential contributions for those over 50 to $20,000.

An even higher catch-up contribution limit applies for employees aged 60, 61, 62 and 63 who participate in SIMPLE plans. For 2025, this higher catch-up contribution limit is $5,250.

Thanks to SECURE 2.0, individuals can contribute a higher amount to certain applicable SIMPLE retirement accounts—typically those belonging to small employers with up to 25 employees. For 2025, this higher amount remains $17,600. A catch-up limit also applies to employees aged 50 and over who participate in those applicable SIMPLE plans—for 2025, this limit remains $3,850.

Savers Credit

Some taxpayers are able to claim a tax credit for making eligible contributions to an IRA or employer-sponsored retirement plan. The Saver's Credit, also known as the Retirement Savings Contributions Credit, is targeted to low- and moderate-income workers.

In 2025, income limits are $79,000 for married couples filing jointly in 2025, up from $76,500 in 2024. The limit increases to $59,250 for heads of household in 2025, up from $57,375 in 2024. And, for singles and married couples filing separately, the amount increases to $39,500 in 2025, up from $38,250.

Defined Benefit Plans

Defined benefit plans aren't as popular as they used to be—they’re typically associated with old-school pensions. However, they’re still around for some businesses who appreciate the deductions on the employer side available for contributions.

In 2025, the limit on the annual benefit under a defined benefit plan will increase to $280,000, up from $275,000 in 2024.

QLACs

A qualified longevity annuity contract (QLAC) allows you to convert funds in a qualified retirement plan—like your 401(k) or IRA—into an annuity. The dollar limit on premiums paid for a QLAC increased to $210,000 in 2025, up from $200,000 in 2024.

Qualified Charitable Distributions

A qualified charitable distribution (QCD) allows you to roll funds directly from your IRA to a qualified charity. Those amounts can be used to satisfy your required minimum distributions (RMDs) for the year and the amount donated is excluded from your taxable income—you won’t even have to itemize to do it.

The total amount of QCDs that you can exclude from your gross income increased to $108,000 in 2025, up from $105,000 in 2024.

In addition, as part of SECURE 2.0, you can make a one-time election for a QCD to a split-interest entity. That amount was initially $50,000, but adjusted for inflation, it will be $54,000 in 2025, up from $53,000 in 2024.

Domestic Violence Victim Distributions

Typically, when you make an early withdrawal from your retirement plan, you are socked with a 10% additional tax (an early withdrawal penalty)—unless it's subject to an exception. As part of the SECURE 2.0 Act, an exception now exists for victims of domestic abuse. The exception allows withdrawals of up to $10,000 (indexed for inflation) or 50% of the present value of the plan's non-forfeitable accrued benefit (vested accrued benefit), whichever is less. The adjustment for 2025 increases the amount from $10,000 to $10,300.
