2026 401(k) and IRA Contribution Limits: New IRS Caps, Catch-Up Rules, and How to Plan Your Deferrals

Every fall, the IRS updates key retirement contribution caps that shape how much US workers can defer into workplace plans and IRAs for the coming year. For tax year 2026, those official cost-of-living adjustments matter if you are trying to max a 401(k), bump catch-up savings after 50, or coordinate traditional and Roth IRA contributions with your income.

This guide walks through the new IRS elective-deferral and IRA limits, age 50+ and ages 60–63 catch-up rules under SECURE 2.0, how employer matches interact with annual additions, Traditional and Roth IRA phase-outs, a brief note on SIMPLE plans, a practical planning checklist, and common mistakes to avoid. Figures below come from IRS newsroom release IR-2025-111 and Notice 2025-67. Always re-check IRS.gov because guidance can be updated.

What Changed for 2026: Key IRS Limits at a Glance

Compared with 2025, the IRS raised several headline retirement dollar limits for 2026. The table below summarizes the figures most US employees and IRA savers track when setting payroll deferrals and personal contributions.

Limit	2025	2026
401(k) / 403(b) / governmental 457 / TSP elective deferral	$23,500	$24,500
Age 50+ catch-up (most of those plans)	$7,500	$8,000
Typical age 50+ combined deferral + catch-up	$31,000	$32,500
Ages 60–63 higher catch-up (SECURE 2.0, if plan allows)	$11,250	$11,250
IRA contribution limit (Traditional + Roth combined ceiling)	$7,000	$7,500
IRA age 50+ catch-up	$1,000	$1,100
IRA age 50+ total	$8,000	$8,600
Defined contribution annual additions (employee + employer; catch-ups separate)	$70,000	$72,000
SIMPLE IRA general employee deferral	(prior year)	$17,000

401(k), 403(b), Governmental 457, and TSP Elective Deferrals

For 2026, employees who participate in most 401(k), 403(b), governmental 457 plans, and the federal Thrift Savings Plan (TSP) can electively defer up to $24,500 of compensation — up from $23,500 in 2025. That elective-deferral limit is the employee salary-reduction ceiling for the calendar year under those plan types (subject to plan rules and compensation).

Two distinctions trip people up every year:

• Employer match does not reduce your employee deferral limit. Matching contributions and other employer nonelective contributions are separate from the $24,500 elective-deferral cap. You can still aim to defer the full employee limit even if your employer also contributes.
• The annual additions limit is a separate overall ceiling. For 2026, the defined contribution annual additions limit is $72,000 (employee + employer contributions for the limitation year, with catch-up contributions generally treated separately under IRS rules). High earners with generous profit sharing or large employer contributions should confirm how their plan counts annual additions — see the IRS retirement topics / COLA table and Notice 2025-67.

Roth and traditional 401(k) elective deferrals usually share the same employee deferral limit. Switching sources does not create a second $24,500 bucket — it reallocates that one ceiling (subject to plan design).

Governmental 457(b) plans can have coordination nuances for workers who also participate in a 401(k) or 403(b). TSP participants should follow TSP election procedures. Always read your plan materials rather than assuming every workplace plan works identically.

Catch-Up at 50+ and the Ages 60–63 “Super” Catch-Up

Once you turn 50 (eligibility follows IRS age rules for the year), most 401(k), 403(b), governmental 457, and TSP participants can make an additional catch-up contribution above the regular elective-deferral limit — if the plan permits catch-ups.

For 2026, that standard age 50+ catch-up is $8,000 (up from $7,500 in 2025). Combined with the $24,500 base deferral, many eligible participants can contribute up to $32,500 in employee elective deferrals plus catch-up for the year.

SECURE 2.0 also created a higher catch-up for participants who are ages 60, 61, 62, or 63 during the year. For 2026, that higher catch-up remains $11,250 instead of the $8,000 standard catch-up — again, only if your plan allows it. In other words, ages 60–63 may have a larger catch-up window than other age-50+ savers, but plan adoption matters. Confirm with HR or your plan administrator whether the higher catch-up is available and how to elect it in payroll.

Catch-up contributions are optional and still require eligible compensation and plan participation. Some plans use a separate catch-up election or automatic spillover after you hit the base limit; others need an early deferral-percentage increase so payroll can reach the higher total before December 31.

IRA Limits for 2026: Traditional and Roth Share One Ceiling

The annual IRA contribution limit for 2026 is $7,500, up from $7,000 in 2025. The IRA catch-up for individuals age 50 and over is $1,100 for 2026 (up from $1,000), for a combined $8,600 when eligible.

Traditional and Roth IRAs share that single contribution ceiling. You do not get $7,500 to a Traditional IRA plus another $7,500 to a Roth IRA for the same person in the same year. You can split the allowed amount between Traditional and Roth (subject to Roth income eligibility), but the combined contributions generally cannot exceed the annual limit (plus catch-up if applicable), and you still need sufficient taxable compensation.

Income phase-outs matter in two different ways:

• Traditional IRA deduction phase-outs (when you or your spouse is covered by a workplace retirement plan) affect whether contributions are deductible — not whether you can contribute at all in many cases.
• Roth IRA contribution phase-outs can reduce or eliminate the amount you may contribute directly to a Roth IRA based on modified AGI and filing status.

Traditional IRA deduction phase-outs for 2026 (workplace plan coverage)

• Single, covered by a workplace plan: $81,000–$91,000
• Married filing jointly, contributing spouse covered: $129,000–$149,000
• Non-covered spouse married to a covered spouse: $242,000–$252,000
• Married filing separately, covered: $0–$10,000

Roth IRA contribution phase-outs for 2026

• Single / Head of Household: $153,000–$168,000
• Married filing jointly: $242,000–$252,000
• Married filing separately: $0–$10,000

These ranges come from the IRS 2026 COLA guidance in Notice 2025-67 / IR-2025-111. Phase-out mechanics are gradual inside each range. If your income sits near a band edge, run the numbers carefully — or ask a tax pro — before assuming a full Roth contribution is allowed.

Some higher-income households consider a backdoor Roth (nondeductible Traditional IRA contribution, then Roth conversion). Form 8606, pro-rata, and timing issues apply. Treat this only as a concept: confirm with a qualified tax professional — this article does not provide step-by-step tax advice.

SIMPLE Plans (Brief Note)

For SIMPLE IRA arrangements, the IRS set the general employee deferral limit for 2026 at $17,000. SIMPLE plans have their own catch-up and employer rules. If your workplace uses a SIMPLE instead of a 401(k), use the SIMPLE limits — do not assume the $24,500 401(k) deferral applies.

Practical Planning Checklist for US Workers

Use this checklist to turn the 2026 IRS numbers into concrete payroll and IRA actions:

1. Confirm your plan type and catch-up features. Is it a 401(k), 403(b), governmental 457, TSP, or SIMPLE? Does it allow age 50+ catch-ups and the ages 60–63 higher catch-up?
2. Set or raise your payroll deferral election early. Workplace elective deferrals generally must be made from pay during the calendar year. Waiting until November often means you cannot catch up to the full annual limit.
3. Model employer match separately from the employee deferral cap. Contribute at least enough to capture the full match if you can, then decide whether to pursue the full $24,500 (or higher catch-up total) based on cash flow and tax goals.
4. Consider a mid-year bump. After a raise, bonus, or expense drop, increase your deferral percentage so you still finish the year near your target without overshooting cash needs.
5. Coordinate IRA contributions with workplace savings. Remember Traditional and Roth IRAs share one ceiling ($7,500 / $8,600 age 50+). Watch deduction and Roth contribution phase-outs for 2026.
6. Know the deadline difference. Workplace plan elective deferrals generally follow the payroll / calendar year. IRA contributions for a tax year can usually be made until the unextended federal tax-filing deadline for that year (confirm the exact date each spring on IRS.gov).
7. Document Roth vs traditional choices. Pre-tax deferrals lower taxable wages now; Roth aims for tax-free qualified withdrawals later. Marginal rate and expected retirement bracket matter — get personalized advice if unsure.
8. Re-verify IRS figures before maxing. Re-check IR-2025-111 and the COLA limitations page; guidance can be updated.

Common Mistakes

• Confusing employer match with the employee deferral limit. Match does not use up your $24,500 elective-deferral room. Annual additions ($72,000 for 2026, catch-ups generally separate) is the broader employee+employer ceiling to watch if you receive large employer contributions.
• Missing the catch-up election. Turning 50 (or entering ages 60–63) does not automatically max you out. Update payroll elections and confirm the plan supports the catch-up you expect — especially the $11,250 ages 60–63 amount.
• Mixing up Roth income limits with Traditional IRA contribution ability. Roth IRA direct contributions phase out by income. Traditional IRA contributions may still be allowed when deductions phase out — deductibility and Roth eligibility are different tests.
• Assuming IRA and 401(k) deadlines work the same way. You generally cannot make up missed 401(k) deferrals after the year’s last paycheck the way you can sometimes fund a prior-year IRA before the tax deadline.
• Ignoring plan documents. IRS limits are ceilings; your plan can be stricter or delay the higher catch-up.
• Overlooking SIMPLE vs 401(k) differences. Using $24,500 instead of the $17,000 SIMPLE deferral can cause failed elections.

Putting the 2026 Caps to Work

The 2026 IRS updates give many US workers more room: $24,500 elective deferrals for popular workplace plans, $8,000 standard catch-up (or $11,250 for ages 60–63 when allowed), $7,500 / $8,600 IRA limits, and a $72,000 annual additions figure for employee-plus-employer planning. Pair those caps with cash flow, match policy, and taxes.

Start with payroll elections you can sustain, capture match you would otherwise leave on the table, then decide whether IRAs should fill remaining gaps within phase-out rules. Re-read IR-2025-111 and Notice 2025-67 on IRS.gov, and bring edge cases — high income, multiple plans, backdoor Roth concepts, or ages 60–63 catch-up availability — to a qualified professional.
