Key Takeaways
- The Roth catch-up mandate now applies starting in 2026: workers 50+ whose prior-year FICA wages from their employer exceeded $150,000 (raised from the original $145,000 statutory figure) must make catch-up contributions as Roth (after-tax).
- 2026 is a 'good faith compliance' year for the Roth catch-up rule; the final regulations formally apply starting in 2027, when strict compliance is required.
- New 401(k) and 403(b) plans established after December 29, 2022 must now automatically enroll employees at 3%-10%, escalating 1% annually, as of the 2025 plan year and continuing into 2026.
- Most retirement plans must formally adopt SECURE 2.0 plan amendments by December 31, 2026 (or January 1, 2027 for governmental and collectively bargained plans).
- Starting in 2027, the nonrefundable Saver's Credit is replaced by the Saver's Match - a 50% federal matching contribution of up to $1,000 per person, deposited directly into your retirement account.
- First Saver's Match deposits (for 2027 contributions) are expected in early 2028.
SECURE 2.0 has been rolling out in phases since it passed in 2022, and 2026 is the year several of its biggest provisions stopped being “coming soon” and started being real. The Roth catch-up mandate for high earners is now in effect. Mandatory auto-enrollment applies to newly created plans. And in 2027, the government starts directly matching retirement contributions for lower-income savers through the new Saver’s Match. Here’s what’s actually changed and what’s still ahead.
The Roth Catch-Up Mandate: What’s Actually in Effect Now
The most consequential SECURE 2.0 change for higher earners is the mandatory Roth catch-up rule, and 2026 is the year it stopped being theoretical.
If your FICA wages from your plan’s sponsoring employer exceeded $150,000 in the prior calendar year, any catch-up contributions you make in 2026 must be designated as Roth — after-tax dollars, with tax-free qualified withdrawals in retirement. That threshold was adjusted upward from the SECURE 2.0 Act’s original $145,000 figure when the IRS issued its final regulations in September 2025, and it’s now indexed to inflation going forward.
Here’s the nuance that trips people up: the Treasury and IRS finalized this rule in September 2025, but gave plans a transition year. For 2026, plan administrators only need to follow a “reasonable, good faith interpretation” of the statute — meaning some flexibility still exists in exactly how it’s implemented. Starting in 2027, the full final regulations apply strictly, with no more good-faith cushion. If your plan doesn’t yet offer a Roth option, this could technically block you from making any catch-up contributions at all until one is added — worth confirming with your plan administrator now rather than waiting until 2027.
There’s a small carve-out worth knowing: plans aren’t required to correct catch-up contributions that should have been Roth if the error is $250 or less, and the rule doesn’t apply to the special 15-year-of-service catch-up available to long-tenured employees in 403(b) plans at schools, hospitals, and nonprofits.

Mandatory Auto-Enrollment for New Plans
A separate SECURE 2.0 provision quietly became mandatory rather than optional: employers establishing a new 401(k) or 403(b) plan after December 29, 2022 must automatically enroll eligible employees, generally starting with the 2025 plan year and continuing now into 2026.
The mechanics: new hires (and existing employees not already participating) must be defaulted into the plan at a deferral rate between 3% and 10% of pay, unless they actively opt out or choose a different rate. That rate must then increase by 1 percentage point each year until it reaches at least 10% (and no more than 15%), unless the employee intervenes. Employees always retain the right to opt out entirely or set their own contribution level.
This doesn’t apply retroactively to plans that already existed before the law passed, so if you’ve been with your employer for years under an older plan, nothing changes here. But if you’re joining a company with a newly established plan, don’t be surprised to see a default deferral already coming out of your paycheck — check your rate and adjust it if 3–10% isn’t right for your situation.
Plan Amendment Deadline: December 31, 2026
Behind the scenes, plan sponsors have been racing against a deadline that directly affects how quickly these provisions show up in your specific plan. Under IRS Notice 2024-2, most qualified retirement plans have until December 31, 2026 to formally amend their plan documents to reflect the full slate of SECURE 2.0 changes — governmental plans and those under collective bargaining agreements get until January 1, 2027.
This is also why adoption of features like auto-portability — the provision that lets a small 401(k) balance automatically follow you to a new employer’s plan when you change jobs — is still uneven across employers. Expect a wave of plan amendment announcements through the rest of 2026 as recordkeepers finalize this work ahead of the deadline.
What’s Coming in 2027: The Saver’s Match
The single biggest SECURE 2.0 change still ahead is the replacement of the existing Saver’s Credit with the Saver’s Match, effective for contributions made starting in 2027.
Today’s Saver’s Credit is a nonrefundable tax credit — meaning it can only reduce your tax bill to zero, and does nothing for people who don’t owe enough tax to use it. The Saver’s Match fixes that by converting the benefit into an actual federal matching contribution, deposited directly into your retirement account regardless of your tax liability.
Here’s how it will work: the government matches 50% of your retirement contributions, up to $2,000 in contributions per person — meaning a maximum match of $1,000 annually. The match phases out based on income. For single filers, the full match applies at adjusted gross income of $20,500 or below, phasing out completely by $35,500. For married couples filing jointly, the full match applies up to $41,000 in AGI, phasing out by $71,000. (These figures adjust for inflation, so confirm the exact numbers closer to 2027.)
One important timing detail: the match is based on 2027 contributions, but the actual deposits into your account aren’t expected until early 2028 — so don’t expect to see this money show up immediately after you contribute.
Looking Ahead: 2028 and Beyond
The next milestone to watch isn’t a new law — it’s implementation. Early 2028 will be the real-world test of whether the Saver’s Match actually reaches the lower-income savers it’s designed for, since that’s when the first matching deposits based on 2027 contributions are expected to land. Expect the IRS and Treasury to issue additional operational guidance through 2027 on exactly how those matching deposits get processed and which account types can receive them.
On the compliance side, 2027 is when the “good faith” flexibility on the Roth catch-up rule disappears entirely — plans that haven’t fully nailed down their implementation by then will be operating without a safety net. If your employer’s plan still doesn’t offer a Roth catch-up option, 2027 is the year to push for clarity, since strict enforcement begins.
