The SECURE 2.0 Act of 2022 was signed December 29, 2022 and made dozens of changes to retirement law. Most are narrow. A few actually move the numbers that matter for retirement planning.
The provisions took effect in stages: some in 2023, more in 2024, the most significant ones in 2025, and one major change still coming in 2026. Here's what's in effect now and what it means for your retirement math.
RMD age is now 73, not 72
If you were born between 1951 and 1959, your required minimum distributions from IRAs, 401(k)s, and most other tax-deferred accounts must begin by April 1 of the year after you turn 73. The previous threshold was 72.
If you were born in 1960 or later, the age is 75, so the first of those RMDs comes in 2035.
If you were already taking RMDs before 2023, nothing changed. The new age only applies if you hadn't yet hit the required start date.
The later start mostly helps people who don't need the money and can let it keep growing tax-deferred. The catch is that a bigger balance means bigger required withdrawals later, all taxed as ordinary income. If you need the cash flow, the change is irrelevant. You can always take more than the minimum.
Use the RMD calculator to run your specific numbers based on your account balance, age, and IRS life expectancy tables.
Super catch-up contributions for ages 60-63: starting 2025
The standard catch-up contribution for 401(k), 403(b), and TSP accounts is $8,000 for 2026 for participants age 50 and older. SECURE 2.0 created a higher limit specifically for ages 60, 61, 62, and 63.
Starting in 2025, those participants can make a larger catch-up. For 2026 it's $11,250 instead of $8,000, an extra $3,250 a year in the four-year window before the limit drops back to the standard catch-up at 64.
Combined with the 2026 base deferral limit of $24,500, ages 60-63 can contribute $35,750 per year to a 401(k). For SIMPLE IRA and SIMPLE 401(k) participants, the 60-63 catch-up for 2026 is $5,250, against a standard SIMPLE catch-up of $4,000 (IRS Notice 2025-67).
Whether this matters to you depends on whether you're already maxing out your 401(k). If you're not hitting the base limit, the catch-up expansion doesn't help. If you are maxing it out, this is an additional $3,250 per year (2026) in tax-deferred savings during what is often a peak earning period.
Roth catch-up mandate for high earners: starting 2026
This one requires planning. Starting January 1, 2026, anyone whose prior-year wages subject to FICA exceeded $150,000 must make catch-up contributions on a Roth basis. No pre-tax catch-up allowed.
In practice: if your W-2 wages were above $150,000 in 2025, your 2026 catch-up contributions can only go into a Roth 401(k). Pre-tax catch-up contributions to a traditional 401(k) won't be permitted for you.
If your plan doesn't offer a Roth option, you can't make catch-up contributions at all. The IRS delayed enforcement of this rule to 2026 (Notice 2023-62) to give plans time to add Roth features.
Whether mandatory Roth treatment hurts you depends on your tax situation. Roth contributions are after-tax now and produce tax-free distributions in retirement. If you expect to be in a lower tax bracket in retirement than you are today, the mandatory Roth treatment costs you money relative to the traditional catch-up. If you expect a similar or higher bracket, it's neutral or beneficial.
The $150,000 threshold (indexed from the original $145,000) refers to the prior year's FICA wages from the employer sponsoring the plan, not total income, so self-employment income doesn't count.
High earners who are already running Roth conversion strategies through the backdoor Roth should factor this into their overall Roth balance projections.
529 to Roth IRA rollovers: starting 2024
If a 529 education account has been open for at least 15 years and the beneficiary won't use the full balance for education, SECURE 2.0 allows rolling unused assets into a Roth IRA for the beneficiary.
The limits are tight. The rollover counts as an IRA contribution, so it's subject to the annual IRA contribution limit ($7,500 in 2026). The lifetime maximum per beneficiary is $35,000. Contributions made to the 529 in the last five years are ineligible to roll over. The beneficiary must have earned income at least equal to the amount being rolled.
This is useful for families who overfunded a 529 because a child got a scholarship or chose a less expensive school. At $7,500/year, it takes about five years to move $35,000. It's not a windfall, but it's a tax-advantaged exit from what would otherwise be a stuck account.
Student loan matching: starting 2024
Employers can now treat qualified student loan payments as elective deferrals for purposes of calculating matching contributions. If an employee pays $500 per month toward student loans and the employer has a 4% match, the employer can make the matching contribution even though the employee isn't putting anything into the 401(k).
The intent is to let recent graduates with heavy loan payments still accumulate employer match while prioritizing debt repayment. This is entirely optional for employers and requires a plan amendment. Not all plans offer it. Check with your HR department.
Auto-enrollment: effective for new plans in 2025
New 401(k) and 403(b) plans established after December 29, 2022 must automatically enroll eligible employees at a contribution rate between 3% and 10% of compensation. The rate must escalate by 1% per year until it reaches at least 10%, capped at 15%.
Existing plans are exempt. Employees can opt out. Businesses with 10 or fewer employees, businesses less than 3 years old, and church and government plans are also exempt.
If you started a job at a company that recently launched a 401(k) plan, you may be enrolled automatically without realizing it. Check your pay stub.
What SECURE 2.0 doesn't change
Defined benefit pensions are largely untouched. The law doesn't affect how pension formulas calculate benefits, survivor options, or lump sum valuations. Social Security benefit formulas are also unchanged. WEP and GPO were repealed separately by the Social Security Fairness Act in January 2025.
The 10% early withdrawal penalty for accessing retirement accounts before 59.5 still applies under the same general framework. SECURE 2.0 added specific exemptions for terminal illness, domestic abuse survivors (the lesser of 50% of the vested balance or a dollar cap that is $10,500 for 2026), and qualified disaster distributions (up to $22,000), but those are narrow carve-outs, not a general loosening.
The 72(t) SEPP rules for penalty-free early distributions also remain intact. If you're planning to access a pre-59.5 IRA without penalty, the 72(t) SEPP calculator still applies and the RMD age change doesn't affect the SEPP calculation method.
Emergency savings accounts (PLESAs): starting 2024
SECURE 2.0 authorized a new account type linked to employer-sponsored retirement plans: the Pension-Linked Emergency Savings Account, or PLESA. Employers may offer PLESAs as a feature of their 401(k) or similar plans. Non-highly compensated employees can keep up to $2,600 (the 2026 limit, indexed from $2,500) in Roth dollars in a PLESA and withdraw it at least once a month without penalty, with no hardship process.
PLESAs are optional for employers and relatively new. Not all employers offer them yet. If yours does, the PLESA provides a liquid emergency fund within the retirement account framework, funded with after-tax contributions, separate from the core 401(k) balance. The cap limits its usefulness as a standalone emergency fund, but as a supplement to a separate emergency savings account, it adds a layer of penalty-free liquidity that the traditional 401(k) does not offer.
Student loan matching contributions: starting 2024
SECURE 2.0 allows employers to make matching 401(k) contributions based on employees' qualified student loan repayments, even if those employees make no 401(k) contributions themselves. If an employee earns $80,000, has $500/month in student loan payments, and the employer matches 4% of compensation, the employer can treat the student loan payment as a 401(k) deferral for matching purposes and contribute $266/month to the employee's 401(k) -- even though the employee made no direct 401(k) contribution.
This provision addresses a genuine dilemma for younger workers: student loan repayment and retirement saving compete for the same dollars. The matching contribution allows employees to get the employer match without diverting loan repayment dollars to the 401(k). Employers must opt into offering this feature. As of 2025, adoption is growing but not universal. Check with your HR department to determine whether your plan has implemented student loan matching.
Small employer retirement plan startup credits
SECURE 2.0 significantly expanded the tax credits available to small employers who start new retirement plans. Employers with up to 50 employees can now receive a tax credit covering 100% of eligible plan startup costs (up from 50%) for up to three years, capped at $5,000 a year.
Employers with 51 to 100 employees get the older 50% credit. A separate credit covers employer contributions for employees earning $100,000 or less, up to $1,000 per employee a year, phasing down over five years. These provisions were designed to increase retirement plan coverage among small business employees, who are significantly less likely to have access to a workplace plan than employees at larger companies.
Roth employer contributions: starting 2023
Before SECURE 2.0, employer matching contributions and profit-sharing contributions to 401(k) plans had to be made on a pre-tax basis. SECURE 2.0 allows employers to offer employees the option to receive employer contributions as designated Roth contributions -- meaning the employer contribution is included in the employee's gross income in the year made, but the funds and their earnings are tax-free in retirement.
This is optional for employers; not all plans have implemented it. If yours has, the choice between pre-tax and Roth employer contributions follows the same logic as the employee contribution choice: Roth makes sense if you expect a higher tax rate in retirement than you have today. Pre-tax makes sense if you expect a lower rate. For most employees, pre-tax employer contributions remain the default, but the Roth option is now available in plans that adopt it.
Long-term care premium distributions: starting 2026
Starting with distributions after December 29, 2025, SECURE 2.0 allows distributions from 401(k)s and other qualified defined contribution plans to pay for certified long-term care insurance premiums without the 10% early withdrawal penalty. The distribution is still subject to ordinary income tax, but the penalty is waived. The annual limit is the least of the premium, 10% of your vested balance, or a dollar cap that is $2,600 for 2026. This is a narrow provision -- it does not allow penalty-free distributions for long-term care expenses directly, only for qualified long-term care insurance premiums -- but it acknowledges the significant and growing burden of long-term care costs on retirement planning.
Long-term care insurance has become increasingly expensive, and many financial plans now treat it as a major retirement risk category alongside market risk and longevity risk. The ability to fund premiums from a retirement account without penalty modestly improves the after-tax economics of maintaining coverage, particularly for retirees who are already past 59.5 and taking distributions anyway.
What SECURE 2.0 did not change
Several retirement planning fundamentals were not affected by SECURE 2.0. The Roth IRA contribution income phase-out limits still apply, adjusted annually for inflation. The backdoor Roth IRA strategy, a non-deductible traditional IRA contribution followed by a Roth conversion, was left alone. The pro-rata rule for Roth conversions still applies to taxpayers with pre-tax IRA balances. The 10% early withdrawal penalty structure remains intact except for the specific new exemptions added by the Act.
The Social Security benefit calculation was not changed by SECURE 2.0. Decisions about Social Security claiming timing -- when to begin benefits, whether to coordinate with a spouse -- remain entirely independent of SECURE 2.0 and are governed by Social Security rules, not ERISA. Use the Social Security calculator at the Social Security calculator for that analysis. Use the RMD calculator at the RMD calculator to model mandatory distributions based on your current account balance and projected age-73 RMD start date under the new rules.
SECURE 2.0 and Roth IRA income limits
SECURE 2.0 did not eliminate the income phase-out for direct Roth IRA contributions. For 2026, the phase-out runs from $153,000 to $168,000 for single filers and from $242,000 to $252,000 for married filing jointly (IRS Notice 2025-67). Above the top of the range, direct Roth IRA contributions are not permitted. The backdoor Roth IRA -- a non-deductible traditional IRA contribution converted to Roth -- remains the standard workaround for high earners, and SECURE 2.0 did not change or eliminate it.
The pro-rata rule still applies: if you hold pre-tax IRA funds, the conversion is partially taxable based on the ratio of pre-tax to after-tax IRA assets. The backdoor Roth calculator at the backdoor Roth calculator models the tax impact based on your specific IRA balances.
The SECURE 2.0 provisions most people will actually feel
Of all the changes in SECURE 2.0, four have the broadest practical impact. First: the RMD age increase to 73 (75 for those born in 1960 or later) -- this affects everyone with a tax-deferred retirement account. Second: the super catch-up for ages 60-63 -- this affects workers in those ages who are maxing their 401(k) contributions. Third: the mandatory Roth catch-up for high earners starting 2026 -- this requires planning for anyone earning above $150,000 who makes catch-up contributions. Fourth: the 529-to-Roth rollover -- this benefits families with funded 529 accounts and adult beneficiaries who need a Roth IRA.
The other provisions -- PLESAs, student loan matching, small employer credits, Roth employer contributions -- are valuable but depend on your employer choosing to implement them. They require nothing from you unless your employer acts first. Verify with your benefits administrator which SECURE 2.0 features your plan has adopted and in what form.
Planning around the 2026 Roth catch-up mandate
The mandatory Roth catch-up for high earners is the 2026 change that needs planning. If your 2025 FICA wages from your employer exceeded $150,000, your 2026 catch-up contributions to a 401(k) will be required to go into a Roth account. Confirm your plan offers a Roth option. If it doesn't, you can't make catch-up contributions until it does, so ask HR.
If your plan does offer Roth, model whether the mandatory Roth treatment of the catch-up is beneficial for your specific tax situation. Roth contributions are after-tax now, tax-free later. If your marginal rate is higher today than it will be in retirement, the mandatory Roth catch-up costs you money relative to the old pre-tax treatment. If your marginal rate will be the same or higher in retirement, Roth is neutral or beneficial. The interaction with IRMAA is also worth modeling: higher Roth account balances reduce future RMDs, which can reduce MAGI in retirement and lower Medicare premium surcharges. Use the calculator at the present value calculator to model those dynamics before the mandate takes effect.
SECURE 2.0 in the context of the full retirement picture
SECURE 2.0 is tax law. It changes the mechanics of tax-deferred and tax-free account contributions and distributions. But the larger retirement income picture for most Americans is not primarily determined by tax mechanics -- it is determined by how much they save, how long they save, and how they sequence income sources in retirement. SECURE 2.0 improves the toolkit. It does not change the math that consistent, substantial contributions over a long career produce better retirement outcomes than optimizing withdrawal rules on a small account balance.
Social Security claiming timing interacts with SECURE 2.0 primarily through the RMD age change. Participants who delay Social Security to 70 while also delaying RMDs to 73 or 75 create a window between retirement and age 70 where neither Social Security nor RMDs are providing income -- a window that must be funded from taxable accounts, Roth accounts, or continued work. Planning that window explicitly, rather than discovering it at 68, produces substantially better outcomes. The Social Security calculator at the Social Security calculator and the RMD calculator at the RMD calculator should be run together as part of a single retirement income plan, not separately.
The pension calculator at the present value calculator remains the starting point for anyone with a defined benefit pension alongside a 401(k). The pension determines the guaranteed income floor. SECURE 2.0's RMD and contribution changes apply to the 401(k) component. Understanding both layers -- the guaranteed annuity income from the pension and the flexible distribution rules for the 401(k) -- is how retirement income planning actually works in practice for the majority of participants who have both types of accounts.
SECURE 2.0: what to do now
If you were born between 1951 and 1959: confirm your new RMD start date is age 73 and model the tax impact of one additional year of deferral. If you are between 60 and 63: confirm you are taking the super catch-up contribution and not leaving the extra $3,750/year on the table. If you earn above $150,000: verify your plan offers a Roth 401(k) option before January 2026 and decide how the mandatory Roth catch-up affects your tax planning. If you have an overfunded 529: model the 529-to-Roth rollover schedule for the beneficiary. SECURE 2.0 created real improvements. The improvements only matter if you act on them. Review the provisions applicable to your situation, confirm which ones your employer's plan has implemented, and run the calculators at the present value calculator to quantify the impact on your specific retirement income plan. The law changed the rules. Your job is to use the new rules to your advantage before the window for each provision closes. The 2026 Roth catch-up mandate and the 2033 RMD age change for those born in 1960 or later are the two remaining major implementation dates. Both are knowable now. Neither requires waiting until the deadline to plan. Plan around them now, before the years narrow. Start with the RMD calculator and the catch-up contribution limits. Both are quantifiable decisions, not judgment calls.
