Catch-up contributions let savers who are 50 or older set aside more than the standard annual limit in a 401(k), 403(b), most 457(b) plans, and IRAs. The extra room recognizes that people closer to retirement often have more cash flow available and less time left to compound it. A newer wrinkle changes the picture for higher earners in 2026: some catch-up dollars must now go in as Roth, after-tax contributions, whether you would have chosen that or not.
What changed in 2026
- The mandatory Roth catch-up rule takes effect. Workplace plan catch-up contributions — 401(k), 403(b), and governmental 457(b) — must be made on a Roth basis for anyone whose prior-year wages from that employer crossed a set high-earner threshold, roughly $145,000 and indexed for inflation.
- The age 60 to 63 "super" catch-up keeps running. Savers in that four-year window can contribute roughly $11,250, more than the standard 50-plus catch-up amount of roughly $8,000, a provision introduced by recent retirement legislation.
- The IRA catch-up now adjusts for inflation. It sat frozen at a flat $1,000 for years and is now indexed, so expect small annual bumps rather than a fixed number going forward.
- More plans now offer a Roth bucket by default, partly to comply with the mandatory catch-up rule and partly because demand for tax diversification has grown.
How catch-up contributions work
Every catch-up-eligible account has a standard annual limit and a separate catch-up amount layered on top, available starting the calendar year you turn 50 — not your exact birthday.

No age-60 step-up |
A hypothetical example: a 61-year-old with access to a 401(k) offering the age 60-63 super catch-up could defer the standard employee limit plus roughly $11,250, instead of the smaller standard catch-up — meaningfully more total space than a 52-year-old in the same plan, who only qualifies for the standard catch-up tier. Treat every dollar figure here as approximate and confirm the current number with your plan or the IRS before setting payroll.
The mandatory Roth catch-up rule
This is the detail catching people off guard in 2026. If your wages from a given employer exceeded the indexed high-earner threshold in the prior year, any catch-up contribution you make to that employer's 401(k), 403(b), or governmental 457(b) must be designated Roth — after-tax — rather than pre-tax. You lose the immediate deduction on that slice of your contribution, though it still grows and comes out tax-free later, matching normal Roth treatment.
This rule applies at the plan level based on that specific employer's wages, and it does not touch IRA catch-up contributions at all, which remain governed by ordinary IRA rules regardless of income. Plans that do not yet offer a Roth option have had to add one, or higher earners lose access to the catch-up entirely in that plan.
Common mistakes
Assuming catch-up contributions apply automatically. Most plans require actively electing the higher deferral rate or dollar amount — hitting 50 does not change your paycheck withholding by itself.
Missing the mandatory Roth trigger. A higher earner who does not realize their catch-up must be Roth can be surprised by a smaller paycheck than expected, since that portion no longer reduces taxable income today.
Ignoring the super catch-up window. The age 60 to 63 tier is worth more than the standard 50-plus catch-up, but it only lasts four years — missing it because of a plan election oversight cannot be made up later.
Confusing IRA and workplace catch-up rules. The IRA catch-up is small, flat, and income-blind; the workplace catch-up is larger, has its own age-60 step-up, and now carries an income-based Roth mandate. Treating them the same leads to under- or over-contributing.
FAQ
At what age can I start making catch-up contributions?
The calendar year you turn 50, for both workplace plans and IRAs — you do not need to wait until your actual birthday.
What is the age 60 to 63 super catch-up?
An enhanced catch-up amount, larger than the standard 50-plus tier, available only in a workplace plan and only during the four calendar years you are 60, 61, 62, or 63.
Do all high earners have to make catch-up contributions as Roth?
Only in workplace plans, and only if prior-year wages from that specific employer crossed the indexed threshold. IRA catch-up contributions are unaffected.
Can I still make a pre-tax catch-up contribution if I am not a high earner?
Yes — the mandatory Roth rule only applies once the wage threshold is crossed; everyone else can still choose pre-tax catch-up contributions where the plan allows it.
