If you are asking “what is Roth IRA vs 401k,” here is the short answer. They are separate retirement-saving arrangements with separate 2026 contribution limits. A Roth IRA is an individual retirement arrangement you open yourself and designate as a Roth IRA when you set it up. A 401(k) is a workplace plan covered by the IRS annual employee contribution limit.
For 2026, the IRS says the annual IRA contribution limit is $7,500. The employee limit for a 401(k), 403(b), governmental 457 plan, or the federal Thrift Savings Plan is $24,500. Those are different buckets. Your savings does not need to wear a tiny “pick one” hat.
The more useful question is this: which rules apply to you, and how much can you set aside? Income can limit Roth IRA contributions. Age can change your catch-up amount. And your Roth and traditional IRA contributions share one combined limit.
What Is a Roth IRA Account?
A Roth IRA is an IRA that must be designated as a Roth IRA when it is set up. Per the IRS Roth IRA overview, you cannot deduct contributions to it. No upfront tax break. The appeal lies elsewhere, and the IRS publications explain the distribution rules.
The IRS also says you can keep contributing after you reach age 70½. You can leave money in your Roth IRA as long as you live. Those details matter when you compare account rules, not just two large numbers.
One limit is easy to miss. Roth and traditional IRAs share the same combined contribution limit. For 2026, that is $7,500. If you fund both types, you do not get $7,500 twice. The IRS, sadly, keeps an eye on this sort of thing.
If you are 50 or older, the 2026 IRA catch-up limit is $1,100, up from $1,000 for 2025. That brings your possible IRA total to $8,600, subject to the other rules.
Want the fine print? The IRS points you to Publication 590-A for contributions and Publication 590-B for distributions. They cover setting up a Roth IRA, withdrawals, and how a Roth IRA differs from a designated Roth account.
Roth IRA vs 401(k): The Core Differences
The clearest differences show up in who opens the account and what limits apply.
- Roth IRA: You set it up yourself. The 2026 IRA limit is $7,500. Your filing status and modified adjusted gross income can reduce what you may put in.
- 401(k): You join through your employer. The 2026 employee limit is $24,500, up from $23,500 for 2025.
- Age 50 catch-up: $1,100 for IRAs. $8,000 for most 401(k), 403(b), governmental 457, and Thrift Savings Plan participants.
- Sharing rule: Your Roth IRA and traditional IRA contributions count toward one combined IRA limit.
The 401(k) employee limit is bigger. Bigger is not automatically better for you. The accounts follow different rules, and a Roth IRA contribution can shrink as income rises.
Watch the vocabulary, too. The IRS treats a “Roth IRA” and a “designated Roth account” as different things. A Roth IRA is an IRA. A 401(k) sits under the employee-plan limit. Similar words make this feel like alphabet soup. Eat it one spoonful at a time.
Roth IRA Contribution Limits 2026
The IRS 2026 retirement-plan announcement sets the annual IRA contribution limit at $7,500, up from $7,000 for 2025.
If you are 50 or older, add the $1,100 catch-up. The math is short: $7,500 plus $1,100 equals $8,600.
So what is the Roth IRA limit for 2026? Start at $7,500. Then check your income. The dollar limit is not a permission slip that skips the income rules.
Roth IRA Income Limits
The 2026 announcement lists these Roth IRA income phase-out ranges:
- Singles and heads of household: $153,000 to $168,000 (up from $150,000 to $165,000 for 2025).
- Married individuals filing separately: $0 to $10,000. This range is not adjusted for inflation each year.
The IRS says the Roth IRA income ranges rose for 2026 across filing statuses. If your status is not listed above, read the announcement for your figures. If your income sits near a phase-out range, check twice. Near the edge, “close enough” is not a tax category.
A Side Note on the Saver’s Credit
If your income is modest, look at the Saver’s Credit, also called the Retirement Savings Contributions Credit. For 2026, the income limit is $80,500 for married couples filing jointly, $60,375 for heads of household, and $40,250 for singles. It is a quiet perk. Quiet perks are the best kind.
401(k) and 403(b) Limits for 2026
For 2026, if you participate in a 401(k), 403(b), governmental 457 plan, or the federal Thrift Savings Plan, your annual employee limit is $24,500, according to the IRS.
The general catch-up limit for participants 50 and over in most of those plans is $8,000, up from $7,500 for 2025. Add it to $24,500 and you get $32,500.
The IRS also notes a higher catch-up limit that remains $11,250 for 2026 instead of $8,000. It does not apply to everyone. Check the IRS announcement to see whether you qualify before you count on it.
Comparing a Roth IRA vs 403(b)? The same split holds. The IRA limit is $7,500. The 403(b) employee limit is $24,500. A 403(b) sits in the same IRS limit group as a 401(k).
Worked Illustration: Turning Annual Limits Into Monthly Amounts
This is an illustration, not a recommendation. Assumptions: you contribute in 12 even monthly deposits during 2026, you are eligible for the full listed amount, and income limits do not reduce your Roth IRA contribution. Monthly amounts are rounded to the nearest cent. Figures come from the IRS 2026 announcement.
| 2026 contribution category | Annual amount | Calculation | Monthly amount |
|---|---|---|---|
| IRA annual limit | $7,500 | $7,500 ÷ 12 | $625.00 |
| IRA limit with age-50 catch-up | $8,600 | ($7,500 + $1,100) ÷ 12 | $716.67 |
| 401(k) employee annual limit | $24,500 | $24,500 ÷ 12 | $2,041.67 |
| 401(k) with general age-50 catch-up | $32,500 | ($24,500 + $8,000) ÷ 12 | $2,708.33 |
Not every household can hit these numbers, or needs to. The point is scale. A $7,500 limit sounds like a mountain. $625 a month is still a mountain, but now it has a trail marker.
The 1% Fix
Once a month, add up your year-to-date Roth IRA and traditional IRA contributions. Compare the total to the single $7,500 combined 2026 IRA limit, or $8,600 if you are 50 or older. Write the total in one place before you make another deposit.
That is the whole habit. It takes a few minutes. It keeps you from treating your Roth and traditional IRAs as two separate buckets. They are not. The IRS says they share one limit.
Checklist
- Confirm whether you are looking at an IRA limit or a 401(k), 403(b), governmental 457, or Thrift Savings Plan limit.
- Use the $7,500 combined 2026 IRA limit when you review Roth and traditional IRA contributions together.
- If you are 50 or older, check whether the $1,100 IRA catch-up or your workplace-plan catch-up applies.
- Find the Roth IRA income phase-out range for your filing status before you assume the full amount.
- If your income is modest, check the Saver’s Credit income limits.
- Read the IRS 2026 limits announcement for the official current-year figures.
