Catch-Up Contribution: Definition and How It Works

A catch-up contribution is an additional amount that individuals age 50 or older are permitted to contribute to an eligible retirement account above the standard annual contribution limit set by the IRS. Authorized under IRC §414(v) for employer plans and §219(b)(5) for IRAs, catch-up contributions allow workers who may have fallen behind on retirement savings — or who simply want to maximize their tax-advantaged accumulation in the years before retirement — to set aside more money each year. The SECURE 2.0 Act of 2022 (Pub. L. 117-328) significantly expanded catch-up contribution rules by introducing a higher "super catch-up" tier for individuals ages 60–63 and requiring that high-income employees make catch-up contributions on a Roth (after-tax) basis beginning in 2026.

401(k), 403(b), 457(b) — Age 50–59 $23,500 $7,500 $31,000
401(k), 403(b) — Age 60–63 (super catch-up) $23,500 $11,250 $34,750
401(k), 403(b) — Age 64+ $23,500 $7,500 $31,000
SIMPLE IRA — Age 50–59 $16,500 $3,500 $20,000
SIMPLE IRA — Age 60–63 (super catch-up) $16,500 $5,250 $21,750
Traditional or Roth IRA $7,000 $1,000 $8,000

Super catch-up for ages 60–63 (SECURE 2.0, §109): Beginning in 2025, participants who turn age 60, 61, 62, or 63 during the calendar year are entitled to a higher catch-up limit equal to the greater of $10,000 or 150% of the regular catch-up amount, indexed for inflation. For 2026, this produces the $11,250 figure above. The super catch-up reverts to the standard $7,500 amount at age 64 and beyond. This creates a narrow but valuable three-to-four-year planning window immediately before traditional retirement age.

IRA catch-up indexing: Prior to SECURE 2.0, the IRA catch-up was stuck at $1,000 and was not indexed for inflation. SECURE 2.0 §108 began inflation-indexing the IRA catch-up starting with the 2024 tax year, but it has not yet moved from $1,000 because the inflation adjustment threshold has not been reached.

Mandatory Roth Treatment for High-Income Catch-Up Contributions (2026)

SECURE 2.0 §603 requires that employees with FICA wages exceeding $145,000 in the prior calendar year (from the same employer, indexed for inflation) must make all 401(k), 403(b), and governmental 457(b) catch-up contributions on a Roth (after-tax) basis beginning January 1, 2026. Plans that offer catch-up contributions must offer a Roth contribution option to comply; plans without a Roth feature must add one or suspend catch-up contributions for affected employees.

Key points for CPAs and plan administrators:

  • The $145,000 FICA wage threshold is based on wages paid by the employer in the prior calendar year, not the current year.
  • The mandatory Roth treatment applies only to catch-up amounts — the standard $23,500 limit is unaffected and can still be pre-tax.
  • Employees below the threshold are not required to use Roth; catch-ups remain elective.
  • The IRS delayed enforcement of this requirement twice (Notice 2023-75, Notice 2024-2), but the rule is now effective for plan years beginning on or after January 1, 2026.

How Catch-Up Contributions Work in Practice

Elective deferrals — employer plans: Participants direct the additional catch-up amount through their plan's salary deferral election. Most payroll systems and plan administrators require a separate catch-up election, though some plans automatically increase deferrals once the standard limit is hit. Catch-up contributions can be made as pre-tax deferrals (unless subject to the mandatory Roth rule above) or as Roth contributions if the plan offers a Roth feature.

IRA catch-up: The additional $1,000 is contributed directly by the taxpayer to a Traditional or Roth IRA alongside the regular $7,000 contribution. All standard IRA eligibility rules apply — Roth IRA catch-ups are subject to the modified adjusted gross income phaseout, and Traditional IRA deductibility depends on whether the taxpayer is covered by a workplace plan. Age 50 is determined as of December 31 of the tax year.

HSA catch-up: Individuals age 55 or older who are enrolled in a qualifying high-deductible health plan (HDHP) can contribute an extra $1,000 to a Health Savings Account (HSA). Unlike the retirement plan catch-up, the HSA catch-up is not indexed for inflation and has remained $1,000 since it was established in 2004. Each spouse must have their own HSA to contribute their own catch-up; catch-up amounts cannot be contributed to a spouse's HSA.

Planning Considerations for CPAs

Bracket arbitrage — Roth vs. pre-tax catch-up: For clients not subject to the mandatory Roth rule, the choice between pre-tax and Roth catch-up contributions depends on current vs. expected future tax rates. Clients in peak earning years where marginal rates are high often favor pre-tax; clients expecting higher income in retirement (e.g., from Required Minimum Distributions) may benefit from Roth. The super catch-up window at ages 60–63 is particularly valuable for Roth accumulation given the large after-tax amount that can be sheltered.

Interplay with IRMAA: Large pre-tax retirement distributions in retirement (including RMDs) increase modified AGI and can trigger IRMAA Medicare premium surcharges. Routing catch-up contributions to Roth while the client is still working can reduce future RMD-driven MAGI spikes.

Self-employed individuals: Sole proprietors and partners funding a solo 401(k) can contribute catch-up amounts as employee deferrals, on top of their employer profit-sharing contribution (which has its own limit under IRC §415(c)). A self-employed taxpayer age 60–63 with a solo 401(k) can potentially shelter $34,750 in deferrals ($23,500 + $11,250 super catch-up) plus a profit-sharing contribution of up to 25% of net self-employment income, subject to the combined annual additions limit.

Deadline: Catch-up contributions to employer plans must be made by December 31 of the plan year. IRA catch-up contributions have until the tax filing deadline (April 15 of the following year, without extension) — the same deadline as regular IRA contributions. For HSAs, the deadline is also April 15 of the following year.

Plan amendment requirements: Plans that previously suspended catch-up contributions for the period when the mandatory Roth rule was unclear must be amended to reflect compliant procedures. The IRS extended a remedial amendment period under SECURE 2.0 guidance, but plan documents and summary plan descriptions need updating before the 2026 plan year. CPAs advising small business plan sponsors should coordinate with the third-party administrator.
