Roth IRA vs Traditional IRA vs 401(k) (2026): Tax Now or Tax Later?
- Step 1: contribute enough to your 401(k) to get the full employer match.
- Step 2: fund a Roth IRA (up to $7,500 in 2026) if your income allows, especially if you're early in your career.
- Step 3: go back to the 401(k) toward the $24,500 limit.
- Choose Traditional (pre-tax) when your tax rate today is higher than you expect in retirement; choose Roth when it's lower or about the same.

The order to fund them
- 401(k) up to the match. A 50% or 100% match is an instant return no other account can beat.
- Roth IRA (if eligible). Lower costs, any fund you like, and flexible access to contributions. If you earn too much, look at a backdoor Roth.
- Back to the 401(k) toward $24,500.
- HSA if you have a high-deductible plan, then a taxable brokerage account.
Roth or Traditional: the tax-rate test
| Your situation | Lean |
|---|---|
| Student, first job, 10%–12% bracket | Roth |
| Mid-career, 22% bracket, expect similar retirement income | Either; split is reasonable |
| Peak earner, 32%+ bracket | Traditional / pre-tax |
| Expect large pension or big RMDs later | More Roth |
| Want flexibility before 59½ | Roth IRA (contributions accessible) |
Example: you put $7,500 into a Roth IRA at 25 and it grows at a hypothetical 7% a year. At 65 it's worth about $112,000, all tax-free. In a Traditional IRA, the same balance would be taxed as income when you withdraw it.
Rules people miss
- The IRA limit is shared. $7,500 total across all your Roth and Traditional IRAs, not each.
- Roth catch-ups for high earners. Starting in 2026, 401(k) catch-up contributions for people who earned over the threshold in the prior year must go in as Roth.
- You have until the tax deadline. 2026 IRA contributions can be made until April 15, 2027.
- Five-year rule. Roth earnings are only tax-free once the account has been open five years and you're 59½.
The bottom line
Take the 401(k) match first, fund a Roth IRA if you can, then go back to the 401(k). Pick Roth when your tax rate is low today and Traditional when it's high. For the two-account deep dives, see Roth IRA vs Traditional IRA and Roth IRA vs 401(k). Canadian with US ties? Read TFSA vs Roth IRA.
Frequently asked questions
What are the 2026 IRA and 401(k) limits?
The 2026 IRA limit is $7,500, plus a $1,100 catch-up if you're 50 or older. The 401(k) employee limit is $24,500, plus an $8,000 catch-up at 50+, or $11,250 for ages 60 to 63. The IRA limit is shared across Roth and Traditional IRAs.
What is the Roth IRA income limit for 2026?
The ability to contribute phases out between $153,000 and $168,000 of modified AGI for single filers and between $242,000 and $252,000 for married couples filing jointly. Above that, consider a backdoor Roth.
Can I have a Roth IRA and a 401(k) at the same time?
Yes. The limits are separate, so in 2026 you could put up to $24,500 into a 401(k) and $7,500 into an IRA. Having a workplace plan can limit the tax deduction on Traditional IRA contributions, but not Roth eligibility.
Can I withdraw from a Roth IRA before 59½?
You can withdraw your contributions at any time, tax- and penalty-free. Earnings withdrawn early are generally taxed and hit with a 10% penalty unless an exception applies.
Do Roth accounts have required minimum distributions?
Roth IRAs have no RMDs for the original owner, and since 2024 Roth 401(k)s don't either. Traditional IRAs and pre-tax 401(k)s require withdrawals starting at age 73.
Is Roth or Traditional better?
Roth is better if your tax rate in retirement will be the same or higher than today. Traditional is better if your rate today is higher than it will be in retirement. Many people split contributions to hedge.
