401k employer match limits historical / 401k contribution limits by year

Meet Sarah, a 34-year-old marketing manager in Austin, Texas, earning $85,000. She's been maxing out her 401k for years, but she just noticed her employer changed the match formula. To figure out if she's still on track, she needs to understand the limits that apply to her — both the employee deferral limit and the total annual limit (IRC §415).

In 2026, the IRS has set the employee deferral limit at $24,500, up from $23,500 in 2025. The total annual limit — which includes your contributions plus any employer match or profit-sharing — is $72,000. That's the maximum that can go into your 401k from all sources in a single year.

If you're age 50 or older, you can add another $8,000 in catch-up contributions, bringing your personal total to $32,500. Starting in 2025, the SECURE 2.0 Act also allows a special "super catch-up" of $11,250 for those aged 60 to 63, but only if the plan adopts it.

These limits have steadily risen with inflation, but the increases are not automatic — they're set annually by the IRS based on cost-of-living adjustments. The key takeaway: the employee deferral limit has increased by nearly 26% since 2020. If you've been contributing a flat dollar amount, you could be leaving room to save more.

Now consider Mike, a 42-year-old warehouse supervisor in Cleveland, earning $60,000. His employer offers a 50% match on the first 6% of salary. That sounds good, but is it common? According to the Vanguard 2024 How America Saves report, the most common employer match formula is a 50% match on the first 6% of pay, up to 3% of pay contributed by the employer. About 95% of Vanguard recordkept plans offer some form of match, with the average total employer contribution being approximately 4.6% of pay.

What is a "good" employer match in 2026?

A 100% match on the first 3-6% of salary is considered a strong offering. For example, a full 100% match on the first 5% of pay means your employer contributes $5 for every $100 you save, essentially giving you an immediate 100% return on your contribution up to that point. Some tech companies and law firms offer 100% on the first 10% or more, but that's not the norm. The Fidelity 2024 Retirement Savings Assessment similarly found that the average employer match rate is 4.6% of salary, with the most common formula being 50% on the first 6%.

If your employer matches 50% on the first 6%, and you earn $80,000, that's $2,400 per year in free money (6% of $80k = $4,800; 50% of that = $2,400). If you don't contribute at least 6%, you're leaving that on the table. In 2026, the contribution limits are high enough that you can easily exceed the match threshold. The golden rule: always contribute enough to get the full employer match. That is the single highest return investment you'll ever find.

Let's do a practical calculation using a 2026 example. Assume you earn $120,000 and your employer matches 100% of the first 5% of pay. You want to max out your employee deferral limit of $24,500. Your employer's match will be 5% of $120k = $6,000. Combined, that's $30,500, which is well under the $72,000 total limit. So you can contribute the full $24,500.

But what if you're a high earner? Say you earn $400,000 and your employer has a generous profit-sharing plan. In that case, your employee deferral of $24,500 plus a profit-sharing contribution of, say, 10% of pay ($40,000) would total $64,500. That's still under the $72,000 limit. However, if your employer contributes 25% of pay, you'd exceed the limit. The plan would stop contributions once the total hits $72,000. This is called the annual additions limit, and it includes all contributions — employee deferrals, employer matching, and employer non-elective contributions.

A common pitfall: if you have multiple 401k plans (e.g., from a side business or a former job that you haven't rolled over), the limits apply across all plans. You cannot exceed $24,500 in employee deferrals across all 401k plans.

If you do, you'll have an excess deferral that must be removed by April 15 of the following year, or be subject to double taxation — taxed once in the year contributed and again when distributed. Conversely, the $72,000 total limit is per plan, meaning you could technically have $72,000 in each of multiple unrelated 401k plans, but that's rare in practice.

So what should you do in 2026? Here's a step-by-step approach for the average American worker, say a 36-year-old teacher in Denver earning $65,000, or a 52-year-old IT manager in Chicago earning $140,000.

Step 1: Contribute at least enough to get the full employer match

This is non-negotiable. If you earn $65,000 and your employer matches 50% on the first 6%, contribute at least 6% ($3,900/year). Your employer adds $1,950. If you don't, you're giving up an immediate 50% return.

Step 2: Max out your employee deferral if you can

The 2026 limit of $24,500 is $1,000 higher than 2025. For someone earning $140,000, that's about 17.5% of pay. That's a big ask. But if you can afford it, the tax savings are substantial. Assuming a 22% federal marginal tax rate, deferring $24,500 saves you $5,390 in federal income tax. Additionally, most states tax 401k contributions, so you'll save state tax too (e.g., 5% in Colorado = $1,225 saved).

Step 3: Consider a Roth 401k if your employer offers it

Many employers now offer a Roth 401k option. Contributions are after-tax, but withdrawals in retirement are tax-free. This is particularly beneficial if you expect to be in a higher tax bracket in retirement. The 2026 limit for Roth 401k contributions is the same $24,500. If your employer matches, the match goes into a pre-tax account.

Step 4: Don't forget the catch-up if you're 50+

If you're 50 or older, you can contribute an additional $8,000 in 2026. If you're between 60 and 63, ask your plan whether they've adopted the super catch-up of $11,250. If they have, your total personal contribution could be $35,750. The total limit with catch-ups could then reach $80,000 ($72k + $8k or $11.25k).
