Key Takeaways
The 2026 401(k) contribution limit is $23,500 for workers under 50 and $31,000 for those 50 and older, including the $7,500 catch-up provision.
Traditional and Roth IRA limits are $7,000 (under 50) and $8,000 (50+), with Roth IRA eligibility phasing out at $150,000 for single filers and $236,000 for married couples.
SEP IRAs allow up to $70,000 in contributions for self-employed workers, making them one of the most powerful retirement vehicles for high earners.
Workers aged 50+ can contribute up to $39,000 combined across a 401(k) and IRA, not counting employer matching contributions.
Contributing the full 401(k) limit of $23,500 annually at a 7% return from age 30 to 65 would accumulate over $2.4 million in retirement savings.
Every year, the IRS adjusts contribution limits for retirement accounts based on inflation, and 2026 brings several important changes that could affect how much you can save. Whether you're maximizing your 401(k) through your employer, funding a Roth IRA on your own, or running a small business with a SEP IRA, understanding these limits is the first step toward building a tax-efficient retirement strategy.
The numbers matter more than most people realize. The difference between contributing $23,500 to a 401(k) versus the old $23,000 limit may seem small in a single year, but compounded over a 30-year career at a 7% average annual return, that extra $500 per year grows to over $47,000 in additional retirement savings. With the Federal Reserve having cut rates from 4.33% in August 2025 to 3.64% in January 2026, the economic backdrop is shifting — and making the most of tax-advantaged accounts has rarely been more important.
Here's a comprehensive breakdown of every retirement account contribution limit for 2026, including catch-up provisions for workers aged 50 and older, income phase-out ranges for Roth IRAs, and strategies for maximizing your savings across multiple account types.

2026 Retirement Account Limits Comparison
For solo entrepreneurs deciding between a SEP IRA and a Solo 401(k), the choice often comes down to income level and desired contribution flexibility. A Solo 401(k) allows both employee deferrals ($23,500) and employer contributions (up to 25% of compensation), while a SEP IRA only permits employer-style contributions. At lower income levels, the Solo 401(k) often allows larger total contributions.

Conclusion
The 2026 contribution limits may look like incremental adjustments — a few hundred dollars here, a slight inflation bump there — but the cumulative impact of maximizing these accounts over a working career is enormous. A 30-year-old contributing the full $23,500 to a 401(k) annually with a 7% return would accumulate over $2.4 million by age 65 from their own contributions alone, before counting any employer match.
With the Federal Reserve continuing its rate-cutting cycle and inflation showing signs of stabilizing, 2026 presents a favorable environment for long-term investing. Tax-advantaged retirement accounts remain the single most powerful wealth-building tool available to ordinary Americans, and the IRS's annual limit increases ensure that their value keeps pace with the cost of living.
The most important step is simply to start — or to increase your contribution rate if you're not yet at the maximum. Even small annual increases of 1-2% of salary, combined with employer matching, can dramatically alter your retirement trajectory over time. Review your plan's contribution settings, check whether you qualify for catch-up provisions, and consider whether a Roth or Traditional approach better fits your tax situation heading into 2026.

The 401(k) remains the cornerstone of retirement savings for most American workers, and the IRS has set the 2026 employee deferral limit at $23,500 for those under age 50. This represents a $500 increase from the 2025 limit of $23,000, reflecting the IRS's standard inflation-adjustment methodology.
Workers aged 50 and older can take advantage of the catch-up contribution, adding an extra $7,500 on top of the standard limit for a total of $31,000 in employee deferrals. This catch-up provision is one of the most powerful tools available to workers in their peak earning years who may have started saving later than they'd have liked.
It's worth noting that the $23,500 limit applies only to employee elective deferrals — your own pre-tax or Roth contributions. The overall limit for all contributions to a 401(k), including employer matching and profit-sharing, is significantly higher at $70,000 for 2026. If your employer offers a generous match, you may be getting far more than $23,500 in total annual retirement contributions.
Individual Retirement Accounts — both Traditional and Roth — share the same base contribution limit for 2026: $7,000 for those under 50, with an additional $1,000 catch-up for those 50 and older, bringing the total to $8,000.
While the contribution limits are identical, the tax treatment differs significantly. Traditional IRA contributions may be tax-deductible depending on your income and whether you're covered by a workplace retirement plan, reducing your taxable income in the year you contribute. Roth IRA contributions are made with after-tax dollars, but qualified withdrawals in retirement are completely tax-free — including all investment gains.
The Roth IRA comes with income eligibility restrictions that don't apply to the Traditional IRA. For 2026, single filers with a modified adjusted gross income (MAGI) above $150,000 begin to see their Roth IRA contribution limit phased out, with full elimination at $165,000. Married couples filing jointly face a phase-out starting at $236,000, with complete ineligibility at $246,000. If your income exceeds these thresholds, you may still be able to fund a Roth IRA through the backdoor Roth conversion strategy, which involves contributing to a Traditional IRA and then converting to a Roth.
One important distinction: you can contribute to both a 401(k) and an IRA in the same year. The limits are separate, meaning a worker under 50 could potentially defer up to $30,500 across both account types ($23,500 in a 401(k) plus $7,000 in an IRA) before counting any employer match.
Self-employed workers and small business owners have access to retirement accounts with substantially higher contribution ceilings. The SEP IRA (Simplified Employee Pension) allows contributions of up to $70,000 for 2026, or 25% of net self-employment income, whichever is less. This makes the SEP IRA one of the most powerful retirement savings vehicles available, particularly for high-earning freelancers, consultants, and business owners.
The SIMPLE IRA (Savings Incentive Match Plan for Employees) is designed for small businesses with 100 or fewer employees. The 2026 employee elective deferral limit is $16,500, with a catch-up contribution of $3,500 for those 50 and older, bringing the total to $20,000. Employers are required to either match employee contributions dollar-for-dollar up to 3% of compensation, or make a flat 2% non-elective contribution for all eligible employees.
Catch-up contributions are specifically designed to help older workers accelerate their retirement savings, and the 2026 limits make them a significant planning tool. Across all account types, a worker aged 50 or older could contribute substantially more than their younger counterparts:
SIMPLE IRA catch-up: $3,500 additional (total $20,000)
For a worker over 50 with access to both a 401(k) and an IRA, the combined maximum employee contribution is $39,000 ($31,000 + $8,000) — not including any employer match. Over a 15-year period from age 50 to 65, fully utilizing these catch-up provisions at a 7% return could generate over $900,000 in additional retirement savings compared to the standard limits alone.
One important change to watch: the SECURE 2.0 Act introduced a provision for enhanced catch-up contributions for workers aged 60 to 63, allowing up to $11,250 in 401(k) catch-up contributions starting in 2025. This "super catch-up" targets workers in their final years before retirement who may need to make up for lost time. If you fall in this age range, check with your plan administrator to confirm your plan has adopted this provision.
Knowing the limits is only half the equation — the real value comes from building a strategy that takes full advantage of the tax benefits available to you. Here are the most effective approaches for 2026:
Front-load your contributions. If your cash flow allows it, consider maximizing your 401(k) contributions early in the year. With the 10-year Treasury yield at 4.05% and the Fed Funds rate at 3.64% as of early 2026, markets remain volatile, and dollar-cost averaging through front-loading can capture more market upside over the full year. However, be mindful that some employers only match contributions made each pay period — front-loading could cause you to miss matching contributions in later months.
Use the Roth vs. Traditional decision strategically. If you expect your tax rate to be higher in retirement — perhaps due to Required Minimum Distributions, Social Security income, or pension payments — prioritizing Roth contributions now locks in today's tax rate. If you're currently in a high tax bracket and expect lower income in retirement, Traditional pre-tax contributions provide more immediate tax savings.
Stack multiple accounts. Nothing prevents you from contributing to a 401(k), an IRA, and a Health Savings Account (HSA) in the same year. An HSA offers a triple tax advantage — deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses — making it a powerful supplement to your retirement savings. The 2026 HSA contribution limit is $4,300 for individual coverage and $8,550 for family coverage.
Don't forget about your employer match. Before optimizing across multiple accounts, ensure you're contributing enough to your 401(k) to capture the full employer match. This is effectively a 50-100% immediate return on your contribution — no investment in the market can guarantee that.
