If you can fund both a workplace 401(k) and an IRA this year, the usual question is order, not either-or. For many workers the sequence is: capture the employer match, keep a cash buffer, then split leftover dollars between an IRA and higher 401(k) deferrals. This page is that priority map. Account flavor basics: Roth IRA vs 401(k) starter. It is not a full traditional-vs-Roth tax essay.
Exact IRS contribution limits change each year. Read the current IRS 401(k) and IRA limit pages before you set a number.
A practical priority order
- Defer enough in the 401(k) to get the full match (example: 100% of the first 4% of pay). Match math: What is an employer match.
- Hold a starter emergency fund in liquid cash so a repair does not become a 401(k) loan.
- Pay down very high-APR debt when the interest rate clearly beats expected market returns.
- Fund an IRA (Roth if eligible; traditional if deduction rules fit) up toward the annual IRA limit.
- Raise 401(k) deferrals toward the annual employee limit after match + IRA habit are stable.
- After age 50, layer catch-up contributions once the base order is working.
Roth vs traditional inside the 401(k) is a separate switch: Traditional vs Roth 401(k).
When the order flips
| Situation | What often changes |
|---|---|
| No employer match | Skip step 1 match chase; compare IRA fund choice and fees vs the plan menu sooner |
| High plan fees / tiny menu | After the match, favor a low-cost IRA brokerage for surplus |
| Roth IRA income phase-out | Use traditional IRA (deduction may phase out too) or stay in the 401(k); backdoor paths are a different guide |
| Huge match true-up quirks | Ask HR how mid-year deferral changes affect the match before you spike mid-year |
| Self-employed only | Different wrappers (solo 401(k), SEP); this page assumes a W-2 workplace plan |
Worked example: $78,000 salary, 50% match on 6%
Alex earns $78,000 (~$6,500/month gross). The plan matches 50% of the first 6% deferred.
| Step | Monthly action (approx) | Why |
|---|---|---|
| Defer 6% to 401(k) | ~$390 from pay + ~$195 match | Captures the full match (~$2,340/year employer dollars) |
| HYSA buffer | $150 | Builds cash before extra investing |
| Roth IRA (if eligible) | $200 | Outside plan menu; after-tax growth path |
| Later raise | Add 1% more 401(k) when cash is stable | Moves toward the annual deferral limit |
Alex does not max the IRA first while deferring 0% and leaving the match on the table. Alex also does not max the 401(k) while carrying a 26% APR card with no payoff plan.
Checklist
- Write down the match formula and vesting schedule from the benefits portal.
- Set deferrals at least high enough to capture the full match.
- Confirm emergency cash has a home before raising surplus.
- Open or fund an IRA only if eligibility and cash flow allow.
- Choose traditional vs Roth 401(k) and IRA types with this year’s tax picture in mind.
- Each January, re-check IRS limits and adjust autos.
