In short
- For 2026 you can put up to $24,500 into a 401(k) and $7,500 into an IRA. The two limits are separate, so you can use both. At 50 or older you can add $8,000 to the 401(k) and $1,100 to the IRA.
- A traditional account lowers your taxable income now and is taxed when you withdraw; a Roth account gives no deduction but qualified withdrawals are tax-free. Roth IRA contributions phase out between $153,000 and $168,000 of income for a single filer.
- A common order of priorities: the 401(k) up to the employer match, then an IRA, then more 401(k). Withdrawals from an IRA before 59½ generally cost an extra 10% tax.
The 2026 limits
The IRS raised the limits for 2026 (announcement of 13 November 2025). Each applies to your own contributions in the calendar year:
- 401(k), 403(b), governmental 457 plan and the federal Thrift Savings Plan: $24,500, up from $23,500 in 2025.
- Catch-up for age 50 and over in those plans: $8,000, so $32,500 in all. At ages 60, 61, 62 and 63 the catch-up is $11,250 instead.
- IRA, traditional and Roth together: $7,500, up from $7,000. The catch-up for age 50 and over is $1,100.
- SIMPLE plan: $17,000 (or $18,100 in some plans), with a $4,000 catch-up for age 50 and over.
Traditional or Roth
With a traditional account you may deduct the contribution, or it comes out of your pay before income tax in a 401(k), and you pay tax on withdrawals. With a Roth account you cannot deduct the contribution, and qualified withdrawals are tax-free (IRS). The idea is to pay tax at the lower rate: a Roth tends to suit you if your tax rate is low now, a traditional account if it is high now and you expect it lower in retirement. Many people split.
Income limits apply to IRAs. A traditional IRA deduction phases out if you are covered by a workplace plan, between $81,000 and $91,000 for singles and $129,000 and $149,000 for married couples filing jointly. A Roth IRA contribution phases out between $153,000 and $168,000 for singles and heads of household, and between $242,000 and $252,000 jointly.
What each account does best
- 401(k): a high limit, money taken from your paycheck automatically, and often an employer match, which is extra pay for saving. You choose from the plan’s funds.
- IRA: you open it at any broker or bank, with a wide choice of investments. The limit is lower, and you contribute yourself. A Roth IRA has income limits; a traditional IRA deduction may not be available if you have a workplace plan and a higher income.
- You can use both: the limits are separate. The $7,500 limit is shared between all your IRAs, Roth and traditional.
Getting at the money
Take money out of an IRA before age 59½ and you generally pay a 10% additional tax on the taxable part, on top of income tax, unless an exception applies (IRS). Traditional accounts require minimum withdrawals starting at age 73; in a workplace plan you can delay them until the year you retire, unless you own 5% of the company. A Roth IRA has no required withdrawals for the owner: you can leave it as long as you live.
The Saver’s Credit, and a common order
If your income is low, a tax credit may add to the benefit: the Saver’s Credit income limit for 2026 is $80,500 for married couples filing jointly, $60,375 for heads of household and $40,250 for singles.
A common order of priorities is not advice for any one person:
- Contribute to the 401(k) at least up to the employer match.
- Keep an emergency fund, so you do not have to withdraw early.
- Fill an IRA, Roth if your income allows it.
- Go back to the 401(k) up to the limit, then to a taxable account.
