If you have limited dollars to save and two good options — a workplace 401(k) and a Roth IRA — the order of contributions matters. The short answer for most people in their 20s and early 30s: 401(k) first up to the employer match, then Roth IRA to the limit, then back to the 401(k). Here is why, and when that order changes.
The 2026 Contribution Limits
| 401(k) / 403(b) | Roth IRA | |
|---|---|---|
| Annual limit (under 50) | $23,500 | $7,000 |
| Annual limit (50+) | $31,000 (catch-up) | $8,000 (catch-up) |
| Income limit | None | Phase-out: $150K-$165K single, $236K-$246K married |
| Employer match | Yes (if offered) | No |
| Tax on contributions | Pre-tax (reduces taxable income now) | After-tax (no deduction) |
| Tax on withdrawals in retirement | Taxed as ordinary income | Tax-free (qualified withdrawals) |
| Required Minimum Distributions | Age 75 | None (owner’s lifetime) |
The Decision Framework
Step 1: 401(k) up to the employer match
Always contribute enough to your 401(k) to capture the full employer match before putting money anywhere else. The employer match is an instant 50%-100% return on your contribution, which no investment can match. If your employer matches 100% up to 3% of salary, contributing 3% gives you effectively 6% going into your retirement account. This is the highest-return financial action available to most workers.
If your employer offers no match, skip this step and go straight to Step 2.
Step 2: Roth IRA to the annual limit ($7,000 in 2026)
After capturing the full match, the next best use of savings dollars for most people under 40 is a Roth IRA. Why Roth over contributing more to the 401(k)?
- Tax-free growth: Roth withdrawals in retirement are completely tax-free, including all investment gains. 401(k) withdrawals are taxed as ordinary income
- No Required Minimum Distributions: You never have to withdraw from a Roth IRA in your lifetime, giving you complete control over taxation in retirement
- Flexibility: Roth IRA contributions (not gains) can be withdrawn at any age without taxes or penalties, functioning as a flexible emergency backstop
- Tax bracket timing: In your 20s and 30s, you are likely in your lowest lifetime tax bracket. Paying taxes now (Roth) rather than later (traditional 401k) is usually the better bet
Step 3: Back to the 401(k) above the match
After maxing the Roth IRA ($7,000), any remaining dollars go back into the 401(k) up to the $23,500 limit. The 401(k)’s tax deduction still has value — you are reducing taxable income now — and the tax-deferred growth compounds meaningfully over decades even if you pay taxes on withdrawal.
When to Flip the Order
The framework above works for most people, but several situations change the math:
High income now, lower income expected in retirement: If you are currently in the 32% or 35% tax bracket, the immediate tax deduction from traditional 401(k) contributions is more valuable. Pre-tax 401(k) dollars are worth more than Roth dollars when your current rate is high and your retirement rate will be lower.
Your Roth IRA income exceeds the limit: Single filers above $165,000 and married filers above $246,000 cannot contribute directly to a Roth IRA. At those incomes, use the backdoor Roth IRA strategy (contribute to a non-deductible traditional IRA, then convert to Roth) or focus on the Roth 401(k) option if your employer offers one.
Your employer offers a Roth 401(k): Many employers now offer a Roth 401(k) option — after-tax contributions that grow tax-free within the 401(k) structure, with no income limit. If available and you are early in your career, a Roth 401(k) can capture the match and give you tax-free growth without the $7,000 Roth IRA limit. You can use both a Roth 401(k) and a Roth IRA simultaneously.
Your 401(k) has bad investment options: Some employer 401(k) plans have high-fee, low-quality investment choices. If the expense ratios in your plan average above 0.50%, it may be worth prioritizing the Roth IRA (where you choose the investments) over contributions beyond the match amount.
The Tax-Bracket Rule of Thumb
When deciding between Roth and traditional:
- 10%-22% bracket now: Lean Roth. You are in a relatively low bracket; paying taxes now is likely cheaper than paying taxes in retirement when you have accumulated more wealth
- 24%-32% bracket now: Split. Use Roth 401(k) or Roth IRA to diversify tax risk, but also take the pre-tax deduction on some traditional contributions
- 35%-37% bracket now: Lean traditional. The immediate deduction is most valuable at these rates

The Quick Answer for New Grads in 2026
If you just started your first job and your employer offers a 401(k) match:
- Contribute to 401(k): enough to get the full match (often 3%-6% of salary)
- Open a Roth IRA at Fidelity, Vanguard, or Schwab and contribute up to $7,000
- If you have money left after that, increase your 401(k) contributions
This order maximizes free employer money, captures tax-free growth during your lowest-tax years, and leaves you with tax diversification heading into retirement. It is the right starting point for the vast majority of people starting their careers in 2026.
