401(k) Contribution Limits 2026: The $24,500 Deferral, Catch-Up Tiers, and Free Match Math

The 2026 numbers are bigger across the board: employees can defer $24,500 into a 401(k), the combined employee-plus-employer cap rises to $72,000, and catch-up contributions add $8,000 at 50+ (or $11,250 for the 60–63 super catch-up). Meanwhile Roth 401(k)s have no income limit at all — a rule change that makes the Roth vs pre-tax decision a tax-bracket question, not a salary-cap question.

1. The 2026 Limit Stack

  • 402(g) employee deferral: $24,500 — the maximum from your own paycheck.
  • Catch-up age 50+: +$8,000 → $32,500 total (ages 50–59 and 64+).
  • Super catch-up ages 60–63: +$11,250 → $35,750 total, if the plan allows it.
  • 415(c) combined limit: $72,000 for you plus your employer; IRA limit $7,500 on the side.
\text{Total} = \min(\text{Salary} \times \%,\ 24500 + \text{CatchUp}(\text{Age})) + \text{Match}

2. Free Money: The Match Math

The most common formula — 50% of your contribution up to 6% of salary — pays $2,700 on the example's $90,000 salary when you contribute at least $5,400 (6% of salary). The match is calculated on the lesser of your deferral or the 6% base, so contributing below 6% of salary literally leaves dollars on the table; in the calculator, dropping to $4,000 of deferrals cuts the match to $2,000. The match always lands as pre-tax dollars even when your own contributions are Roth.

3. Pre-Tax vs Roth in 2026

Pre-tax contributions cut this year's bill at your marginal rate — $10,800 at 22% saves $2,376 now, with withdrawals taxed later. Roth contributions pay that tax today so qualified withdrawals and all growth come out tax-free. Since 2026, earners with prior-year FICA wages above $150,000 must make their catch-up contributions as Roth (SECURE 2.0's mandatory-Roth rule), and Roth 401(k)s carry no income ceiling — high earners who cannot use a Roth IRA can still fill this one.

4. Election Season Moves

Benefits elections run November–December — the moment to raise a deferral percentage, capture the full match, and check whether your plan allows in-plan Roth conversion and after-tax contributions (the key to the full $72,000). Divide the raise by 26 paychecks to see the take-home hit, then project the balance with the 📈 Compound Interest Calculator, size the finish line with the 🏖️ Retirement Calculator, and check the income leg with the 🛡️ Social Security Calculator — all inside the 💰 Financial Hub.

Frequently Asked Questions (401(k) Contribution)

What is the 401k contribution limit for 2026?

Employees may defer $24,500 of salary into a 401(k) in 2026, up from $23,500 in 2025. Catch-up contributions add $8,000 at age 50 and older (a $32,500 employee maximum), while participants aged 60 through 63 may use an enhanced $11,250 super catch-up for a $35,750 maximum if their plan permits it. The combined employee-plus-employer limit under IRC §415(c) is $72,000.

How does an employer match actually calculate?

Under the standard formula the employer adds 50 cents for every dollar you contribute, up to 6% of your salary. On $90,000 that is a $5,400 contribution base: contribute $10,800 and you capture the full $2,700 match; contribute under $5,400 and the match scales down with you. Contributing at least 6% of salary is the minimum to collect every matching dollar the plan offers.

Should I make pre-tax or Roth 401(k) contributions in 2026?

Pre-tax saves tax now at your marginal rate — $10,800 at 22% keeps $2,376 this year — and wins if your retirement bracket is lower. Roth pays tax now so withdrawals and decades of growth come out tax-free, which wins if you expect equal or higher rates later. Roth 401(k)s have no income limit in 2026, and if your prior-year FICA wages exceeded $150,000, catch-up contributions must be made as Roth.

What happens if I contribute more than the annual limit?

Excess deferrals are taxable in the year contributed and taxed again when withdrawn unless returned with earnings by the April tax-filing deadline — so track payroll closely near year end. The 402(g) limit counts only your own employee deferrals; employer matches and profit sharing apply separately against the $72,000 combined cap. Automatic enrollment plans usually stop you before this happens, but large raises mid-year can push past it.

When should I decide my 401(k) contribution percentage?

During open enrollment, typically November or December for the coming year — that is when you can change payroll deferrals, verify the match formula, and confirm Roth options. Recheck after any raise: a 12% deferral on $90,000 is $10,800 ($415.38 per biweekly paycheck), and the calculator shows how each percentage point moves you toward the $24,500 base limit or your age-50+ maximum.
