Suggested order of contributions

The order, and why

  1. Emergency fund & high-interest debt. A cash cushion and paying off 20%+ APR debt typically come before investing beyond the match.
  2. Employer match. Contribute enough to capture your full employer match before adding unmatched dollars. If you’re filing jointly, each partner captures their match first.
  3. HSA if enrolled in an HSA-eligible high-deductible plan.
  4. Roth IRA — direct if under the income limit, partial in the phase-out, or "backdoor" above it. Filing jointly? Each of you can contribute.
  5. Fill the 401(k)/403(b) employee limit, Roth or pre-tax depending on brackets now vs later.
  6. 457(b), which has a separate limit, if available.
  7. Mega backdoor Roth (after-tax contributions + in-plan conversion) if the plan allows it.
  8. Taxable brokerage for everything else.

FAQ

Why is the employer match first?

A 50% or 100% match is an instant, guaranteed return on the dollars contributed — far more than markets typically deliver in a year. Skipping it leaves part of compensation unclaimed.

Why is the HSA called triple tax-advantaged?

Contributions are deductible (or pre-tax via payroll, which also avoids FICA), growth is untaxed, and withdrawals for qualified medical expenses are tax-free. After 65 it can be used for anything, taxed like a traditional IRA. Family coverage has one shared limit per couple.

Roth or pre-tax?

Roth means paying tax now at today's bracket; pre-tax means paying later at the retirement bracket. If the later bracket is expected to be lower, pre-tax tends to win; if higher, Roth. When it's a toss-up, many households split for tax diversification. State taxes matter too (e.g., moving from a high-tax to a no-tax state favors pre-tax).

What is a backdoor Roth, and what is the pro-rata rule?

Above the Roth IRA income limit, a non-deductible traditional IRA contribution can be converted to Roth. But the IRS treats all of a person's pre-tax traditional, SEP and SIMPLE IRA balances as one pool: if 75% of the pool is pre-tax, 75% of the conversion is taxable. Rolling pre-tax IRA money into an employer plan (if it accepts roll-ins) before year-end is a common way to avoid this. Each spouse's IRAs are tested separately. Reported on Form 8606.

What is a mega backdoor Roth?

Some 401(k) plans allow after-tax (non-Roth) contributions above the $24,500 deferral limit, up to the $72,000 total limit for 2026, plus an in-plan Roth conversion or in-service withdrawal. That moves tens of thousands more per year into Roth. Both features must be offered by the plan.
