The 401(k) vs IRA limits 2027 show a clear gap, because the 401(k) lets you save far more than an IRA. The 401(k) employee limit is projected at $25,500 for 2027, while the IRA limit for 2027 is not yet known. The official 2026 IRA limit is $7,500. Each account has its own rules on income, tax breaks, and investment choice. This guide compares the two side by side to show which plan fits your situation, and how to use both together.
What are the 401(k) vs IRA limits 2027? The 401(k) vs IRA limits 2027 put the 401(k) employee limit at a projected $25,500, while the IRA limit for 2027 is not yet known. The official 2026 IRA limit is $7,500. The 401(k) catch-up is $8,500 at age 50 and over, while the IRA catch-up is $1,100 for 2026.
The 401(k) vs IRA Limits 2027 Side by Side
The 401(k) vs IRA limits 2027 are best understood in a table. The 401(k) figures for 2027 are projections from Milliman, a large actuarial firm, in its final forecast published on October 15, 2026. The Internal Revenue Service, known as the IRS, has not announced the official 2027 limits yet, so every 2027 401(k) number is a projection. The IRA limit for 2027 is not even projected, because Milliman did not include the IRA in its forecast.
| Feature | 401(k) in 2027 | IRA in 2027 |
|---|---|---|
| Employee limit | $25,500 projected | $7,500 in 2026, 2027 unknown |
| Catch-up, 50 and over | $8,500 projected | $1,100 in 2026 |
| Super catch-up, 60 to 63 | $11,750 projected | Not available |
| Total, age 50 and over | $34,000 projected | $8,600 in 2026 |
| Total, ages 60 to 63 | $37,250 projected | $8,600 in 2026 |
| Employer match | Yes, extra on top | No employer match |
| Maximum annual addition | $75,000 projected | Not applicable |
The gap is large, because the 401(k) limit is more than three times the IRA limit, and it grows wider once catch-up money and the employer match are added. A worker age 50 or over could put a projected $34,000 into a 401(k) in 2027, plus the match. The same worker could put only $8,600 into an IRA under the 2026 figures. Most advisers tell workers with a 401(k) at work to start there, and to use the IRA as a second account once the 401(k) is funded.
How the 401(k) Limit Works
The 401(k) side of the 401(k) vs IRA limits 2027 is the bigger number, and it comes with an employer match that the IRA cannot offer. The projected $25,500 limit covers only the money you put in from your own pay, and your employer match sits on top of that. The maximum annual addition, which covers your money plus employer money, is projected at $75,000 for 2027, up from $72,000 in 2026. If your employer matches your contributions, that match is free money, and it is the best reason to fund the 401(k) first.
The 401(k) is tied to your job, which is both a strength and a limit. You can only contribute through payroll, and you can only use the plan your employer offers, with the investment menu your employer chose. That menu is often a short list of funds, and some plans charge higher fees than an IRA you open yourself. But the payroll link is also a strength, because the money comes out before you see it, and saving becomes automatic. Our guide to the 401(k) contribution limit 2027 covers the per-paycheck math.
The 401(k) also offers a Roth option in many plans, which lets you pay tax now and take the money out tax-free in retirement. The same $25,500 limit covers both pre-tax and Roth contributions combined. The catch-up rules are generous too, with a projected $8,500 for age 50 and over, and a super catch-up of $11,750 for ages 60 to 63 under the SECURE 2.0 Act. Our guide to the 401(k) catch-up contribution 2027 covers those age rules in full.
How the IRA Limit Works
The IRA side of the 401(k) vs IRA limits 2027 is smaller, but the IRA gives you freedom that a 401(k) cannot match. The official IRA limit for 2026 is $7,500, which the IRS set in Notice 2025-67, and the IRA catch-up for age 50 and over is $1,100 for 2026. The 2027 IRA limit is not known yet, because Milliman did not project it, and some analysts think it could rise to $8,000, while others think it may stay at $7,500. The IRS will confirm the figure in its notice, expected in mid-November 2026. Do not plan around $8,000 until the IRS says so.
The IRA limit covers both a traditional IRA and a Roth IRA combined, so you cannot put $7,500 into each type. The IRA is an account you open yourself, at a bank, a brokerage, or an online provider, and you fund it with money from your bank account, not through payroll. That freedom means you can choose from thousands of investments, including low-cost index funds, and you can often pay lower fees than a 401(k) plan charges. The trade-off is that you must remember to fund it yourself, and there is no employer match.
The IRA also has income limits that the 401(k) does not have, and those limits decide whether your contributions are tax deductible or even allowed. If you have a 401(k) at work, your traditional IRA contributions may not be fully deductible once your income passes a set threshold. Roth IRA contributions have their own income limits, and if your income is too high, you cannot contribute to a Roth IRA directly at all. The 401(k) has no income limit on who can contribute, so a high earner can always use the 401(k).
401(k) vs IRA Limits 2027: Which Plan Should You Fund First
The 401(k) vs IRA limits 2027 point to a clear order for most workers, and it starts with the employer match. Step one is to contribute enough to your 401(k) to get the full employer match, because the match is free money that no IRA can offer. If your employer matches the first 6 percent of your pay, set your rate at 6 percent at least. Step two depends on your situation: if your 401(k) has high fees or a poor menu, the IRA is a strong step two, because you can pick low-cost funds yourself. If your 401(k) has good low-cost funds, raise your 401(k) rate further first.
Step three is to use the other account once the first two steps are done. If you funded the 401(k) to the match and then maxed the IRA, go back to the 401(k) and raise your rate toward the $25,500 limit. If you funded the 401(k) hard and still have room, open an IRA and fund it up to its limit. You can use both in the same year, because the limits are separate. A worker under age 50 could put $25,500 into a 401(k) and $7,500 into an IRA in 2026 terms, for a combined $33,000, before any employer match.
Your tax situation can change the order, so think about it before you commit. If you are in a high tax bracket now and expect a lower bracket in retirement, pre-tax contributions may save you more. If you are in a low bracket now, perhaps early in your career, Roth contributions may win, because you pay little tax now and nothing later. Many workers split their saving between pre-tax and Roth to hedge their bets.
Using Both Accounts Together in 2027
Using both accounts together is the strongest plan for many savers, and the 401(k) vs IRA limits 2027 make it clear why the combination works so well. The 401(k) gives you the big limit and the employer match, while the IRA gives you investment choice and low fees. A practical split is to fund the 401(k) to the full match, then fund the IRA to its limit. Then return to the 401(k) and raise your rate as far as your budget allows.
The two accounts also give you tax flexibility in retirement, which many savers overlook. If you hold both pre-tax money in a 401(k) and Roth money in an IRA, you can choose which pot to draw from each year. That choice lets you manage your tax bill. In a low-income year, you can draw from the pre-tax pot and pay little tax, and in a high-income year, you can draw from the Roth pot and pay no tax at all. That flexibility is worth building over decades.
There are a few practical rules to keep in mind when you run both accounts. First, track your totals separately, because the 401(k) limit and the IRA limit are separate, and an excess in one account does not offset room in the other. Second, remember the IRA deadline. You can fund an IRA for a tax year up until the tax filing deadline in April of the next year, while 401(k) money must go in by December 31. Third, check the income limits for IRA deductibility and Roth eligibility each year. Our pillar guide, 2027 401(k) limits, covers the full set of projected 401(k) limits for 2027.
A Comparison Most Guides Miss: Fees, Choice, and Control
Most comparisons of the 401(k) vs IRA limits 2027 stop at the numbers, but fees, investment choice, and control matter just as much. A 401(k) plan offers a short menu of funds, often 15 to 30 options, chosen by your employer, and the fees on those funds can vary widely. Some plans offer excellent low-cost index funds, while others charge high fees that eat into your returns year after year. An IRA you open yourself offers thousands of funds, and you can switch providers any time you like. If your 401(k) fees are high, the IRA is the better home for the money beyond the match.
Control is another difference, because an IRA belongs to you alone, while a 401(k) belongs to your employer’s plan. You can move IRA money between providers with a rollover, you can change investments any day, and you keep the account when you change jobs. A 401(k) stays with your old employer when you leave, and you must decide whether to leave it there or roll it into an IRA. Many workers roll old 401(k) money into an IRA when they change jobs, and that move often cuts their fees.
Can I max out both a 401(k) and an IRA in 2027? Yes, you can max out both accounts in the same year, because the limits are separate. The 401(k) limit is projected at $25,500 for 2027, and the IRA limit for 2027 is not yet known, with $7,500 as the 2026 figure. Together they allow $33,000 in 2026 terms.
Frequently Asked Questions
What are the 401(k) vs IRA limits 2027?

Which is better, a 401(k) or an IRA?
Neither is better on its own, because each has strengths the other lacks. The 401(k) offers a much higher limit and an employer match, while the IRA offers wider investment choice and often lower fees. Most savers do best using both.
Can I contribute to a 401(k) and an IRA in the same year?
Yes, you can contribute to both in the same year, and the limits are separate. You could put $25,500 into a 401(k) and $7,500 into an IRA in 2026 terms, for a combined $33,000.
What is the IRA limit for 2027?
The 2027 IRA limit is not known yet, and Milliman did not project it. The 2026 IRA limit is $7,500. Some analysts expect $8,000, while others expect $7,500.
Does the employer match count toward the 401(k) limit?
No, the employer match does not count toward the $25,500 employee limit. The match counts toward the maximum annual addition, projected at $75,000 for 2027. Your own $25,500 is separate from what your employer adds.
What is the 401(k) catch-up limit for 2027?
The 401(k) catch-up for age 50 and over is projected at $8,500 for 2027, and the super catch-up for ages 60 to 63 is projected at $11,750. The IRA catch-up is $1,100 for 2026.
Do income limits apply to 401(k) contributions?
No, there is no income limit on who can contribute to a 401(k). Anyone with a 401(k) at work can contribute, whatever their income. IRA contributions have income limits that affect tax deductibility.
Can I contribute to a Roth IRA if I have a 401(k)?
Yes, you can contribute to a Roth IRA even if you have a 401(k), as long as your income is below the Roth IRA income limit. A high income might still block you.
Should I fund my 401(k) or my IRA first?
Fund the 401(k) first, at least enough to get the full employer match, because the match is free money. Then fund the IRA, especially if your 401(k) has high fees. Then return to the 401(k) and raise your rate.
What happens if I exceed the IRA limit?
If you put in more than the IRA limit, the extra money is an excess contribution, and it faces a 6 percent penalty tax each year until you remove it. Tell your IRA provider as soon as you spot the problem.
Can I roll my old 401(k) into an IRA?
Yes, you can roll an old 401(k) into an IRA when you change jobs, and many workers do, because the IRA often offers lower fees and wider investment choice. A direct rollover avoids tax withholding, so ask for a direct rollover.
What is the Social Security COLA for 2027?
