Every year, the IRS quietly raises the ceiling on how much you can shelter from taxes in retirement accounts. Every year, millions of Americans miss it. With roughly ten weeks left in 2026 and the next set of limits already on the calendar, now is a smart moment to check whether you are using the room you have. This guide walks through the numbers, who they apply to, and a simple way to plan your contributions without straining your budget.

Why contribution limits matter more than most people think

Retirement accounts are one of the few places where the tax code actively helps you build wealth. Money in a traditional 401(k) or IRA can grow tax-deferred, and money in a Roth account can grow and be withdrawn tax-free if the rules are met. The catch is that the space is capped each year, and unused space generally cannot be reclaimed later.

That makes the annual limit a “use it or lose it” opportunity. You do not have to max out every account, but knowing the ceiling helps you decide how much to aim for.

The 2026 limits at a glance

According to IRS figures reported by CPA Practice Advisor (citing IRS Notice 2025-67), the main 2026 limits are:

• 401(k) employee deferral: $24,500, up from $23,500 in 2025.
• Catch-up contribution, age 50 and older: $8,000, up from $7,500, for a total of $32,500.
• “Super” catch-up, ages 60 to 63: $11,250 in place of the regular catch-up.
• IRA annual limit: $7,500, up from $7,000.
• IRA catch-up, age 50 and older: $1,100, up from $1,000.
• SIMPLE plan limit: $17,000 generally, with higher figures for certain plans.

These limits apply to what you contribute. Employer matches and profit sharing are counted under a separate, larger overall limit for defined contribution plans, so a match does not eat into your own deferral room.

401(k) versus IRA: you can use both

A common misconception is that you must choose between a workplace plan and an IRA. In general, you can contribute to both in the same year, because they have separate limits. The trade-off is that having a workplace plan can affect whether your traditional IRA contribution is tax-deductible, depending on your income.

A practical order many savers use:

1. Contribute enough to your 401(k) to capture the full employer match, since that is an immediate return.
2. Consider an IRA, traditional or Roth, for lower fees and wider investment choices.
3. Return to the 401(k) and raise your contribution toward the limit if cash flow allows.

Roth IRA income phase-outs

Roth IRAs come with income limits. For 2026, the reported phase-out ranges are:

• Single and head of household: $153,000 to $168,000 of modified adjusted gross income.
• Married filing jointly: $242,000 to $252,000.

Within the range, the amount you can contribute shrinks; above it, direct Roth IRA contributions are not allowed. If your income is near the line, a tax professional can explain your options, since the rules for workarounds are technical.

The catch-up rules for savers in their 50s and 60s

Catch-up contributions exist for people who started saving late or want to accelerate near retirement. Anyone 50 or older can add the standard catch-up. Those aged 60 through 63 can contribute the higher “super” catch-up amount in workplace plans that allow it.

Two cautions. First, whether your plan offers the higher amount depends on the plan itself, so check with your administrator. Second, recent rules change how catch-up contributions are treated for some higher-earning employees, so confirm the details for your situation before you rely on a deduction.

A hypothetical example: building a monthly plan

This example is hypothetical and for illustration only.

Imagine Maria, age 41, who earns a steady salary. Her employer matches a portion of her 401(k) contributions. She is currently contributing 6% of pay and wonders how to use the rest of 2026.

Her approach:

• She confirms the match formula and makes sure she is contributing enough to receive all of it.
• She calculates how much she has contributed so far this year using her latest pay stub.
• She subtracts that from the $24,500 limit to see the remaining room.
• She divides any amount she wants to add by the number of remaining paychecks and raises her percentage by that much.

Even a one-percentage-point increase, spread across the remaining pay periods, can add meaningful savings without a dramatic change to take-home pay. Maria does not need to hit the limit; she simply picks a target she can sustain.

Traditional or Roth: which fits you?

The choice comes down to when you prefer to pay tax. Traditional contributions may reduce taxable income today, while qualified Roth withdrawals in retirement are generally tax-free. Neither is universally better, because the answer depends on your tax bracket now versus what you expect later.

Some questions to ask yourself:

• Is my income unusually low or high this year? A lower-income year can favor Roth; a high-income year can favor traditional.
• Do I expect higher taxes in retirement? If so, paying tax now through Roth may appeal.
• Do I want flexibility? Splitting contributions between both types can diversify your future tax picture, an approach sometimes called tax diversification.

If your plan offers both options, you do not need to choose just one. Many savers divide contributions and adjust the mix as their circumstances change.

A quick year-end checklist

With the calendar year closing in, a short review can pay off. Set aside thirty minutes and work through these steps:

1. Log in to your plan and note your year-to-date contributions.
2. Compare that figure with the $24,500 limit, or your catch-up-adjusted limit if you are 50 or older.
3. Confirm your employer match formula and whether it is calculated per paycheck or annually.
4. Decide on a realistic target, then update your deferral percentage.
5. Review your beneficiary designations, which are easy to forget and can matter a great deal.
6. Check that your investments still match your goals and risk tolerance.

Small, steady adjustments are usually more sustainable than a single large push, and consistency over many years tends to matter more than any one year’s total.

Common mistakes to avoid

• Front-loading and missing the match. Some plans match per paycheck. If you hit the limit early and stop contributing, you may forfeit match money later in the year. Check your plan’s rules.
• Contributing to the wrong year. The 401(k) deadline is generally the end of the calendar year through payroll, while IRA contributions for a tax year can often be made until the tax filing deadline.
• Ignoring multiple jobs. The 401(k) deferral limit applies to you across all employers, not per plan.
• Overcontributing to an IRA. Excess contributions can trigger penalties, so track totals across all your IRAs.
• Raising contributions without an emergency fund. Locking up money you may need soon can force costly early withdrawals.

Investment choices matter as much as contribution size

Contributing is only the first step. The money still has to be invested. Many workplace plans offer target-date funds, which adjust their mix of stocks and bonds as you approach retirement, and low-cost index funds. Whatever you choose, keep an eye on fees and revisit your allocation periodically so it matches your time horizon and comfort with risk.

It also helps to automate. Setting contributions as a percentage of each paycheck removes the temptation to time the market or skip a month. When your salary rises, consider directing part of the raise to your retirement savings before you get used to spending it. That habit quietly builds wealth over decades.

Frequently asked questions

Can I contribute to both a 401(k) and an IRA in 2026?

Generally yes, since the limits are separate. However, having a workplace plan can limit the deductibility of traditional IRA contributions at higher incomes, so check the rules for your situation.

Does my employer match count toward the $24,500 limit?

No. The $24,500 figure covers your own deferrals. Employer contributions fall under a separate, higher overall plan limit.

Is it too late to increase my contributions for 2026?

Not necessarily. Payroll changes can usually be made within a pay cycle or two, and IRA contributions for a tax year can often be made until the filing deadline. Confirm timing with your plan and a tax professional.
