401(k) Employee Elective Deferrals in 2026 — Part 1 of Our Retirement Plan Series
Every retirement plan strategy for a business owner or professional starts with the same building block: the employee elective deferral. This is the portion of a 401(k) that comes directly out of your own paycheck, before any employer contribution enters the picture, and it is where our seven-part series on retirement plans as tax planning tools begins. Here is exactly what the IRS allows for 2026, and the rule that changed for high earners.
What an Elective Deferral Actually Is
An elective deferral is compensation you choose to redirect from your paycheck into your 401(k) instead of receiving it as current pay. Per IRS Code Section 402(g), you can make this election as a pre-tax traditional contribution, reducing your current taxable income, or as a Roth contribution, which is taxed now but grows tax-free for qualified withdrawals in retirement. Both types count toward the same combined annual limit — the IRS does not give you separate limits for each; it is one shared cap across pre-tax and Roth deferrals together.
The 2026 Limits
For 2026, the standard elective deferral contribution limit under Section 402(g) is $24,500, or 100% of your compensation if that figure is lower. Participants age 50 or older by year-end can contribute an additional $8,000 catch-up amount, bringing their total contribution limit to $32,500. Under the SECURE 2.0 Act, participants who turn 60, 61, 62, or 63 during 2026 qualify for an enhanced "super catch-up" of $11,250 instead of the standard catch-up — a window that applies only during those four specific ages before reverting to the standard catch-up amount at 64.
The Mandatory Roth Catch-Up for High Earners
A significant change under the SECURE 2.0 Act took effect for higher earners: if your prior-year FICA wages from the same employer exceeded a threshold set at $150,000 (indexed), any catch-up contribution you make — standard or super catch-up — must be made as a Roth contribution rather than pre-tax. Regular deferrals up to the standard $24,500 limit are unaffected and can still be pre-tax or Roth by your own election; the mandatory Roth treatment applies only to the catch-up portion for affected high earners. This is a real shift under the SECURE 2.0 Act in the tax character of a contribution many high-income professionals had always made pre-tax.
Are you maximizing your elective deferral — and is your catch-up handled correctly?

How This Fits Into Tax Planning
A pre-tax deferral is a direct, dollar-for-dollar reduction of current taxable income at your marginal rate — the single most reliable lever most employees have each year. A Roth deferral trades that current deduction for tax-free growth and withdrawals later, which tends to favor someone who expects their rate to hold steady or rise. The choice between the two, and how aggressively to use the catch-up provisions as you age, is a genuine annual decision that should be revisited as income and tax brackets change, not set once and forgotten.
Where the Series Goes From Here
Under Section 402(g), the employee elective deferral is only the first layer. Part 2 of this series covers the employer side of a 401(k) — matching contributions and vesting schedules — followed by safe harbor plan design, SEP-IRAs, profit-sharing formulas, and how business owners stack multiple plans together to shelter far more than a standard 401(k) allows alone.
