Benefits, Costs and Risks, and Tax Implications with 401(k) Rollover Decision Options*

​

401(k) Options

​

1. Leaving a 401(k) with a Former Employer (Doing Nothing)

​

Benefits

• Zero immediate effort or paperwork

• Existing investments remain unchanged with no taxable event

• Federal ERISA creditor protection (often stronger than IRA protection)

• If you left the job at age 55+, you may access funds penalty-free (Rule of 55)

​

Costs & Risks

• Plan fees are often higher than comparable IRAs — sometimes significantly so

• Limited investment menu vs. the open market in an IRA

• Required Minimum Distributions (RMDs) still apply at 73, even if forgotten

• Risk of losing track of the account across job changes (this is extremely common)

• Beneficiary designations can become stale or incorrect over time

• Former employers can force-cash-out accounts under $7,000 (as of 2024 SECURE 2.0 rules)

​

Tax Implications

• No immediate tax event — pre-tax money stays pre-tax

• RMDs at 73 will be taxed as ordinary income whether you're paying attention or not

• Missed RMDs trigger a 25% excise tax on the amount not withdrawn

​

Key Decision Point: If the plan has low-cost institutional funds and you're still a few years from RMD age, leaving it temporarily isn't catastrophic. But indefinitely? The forgotten account problem is real — and costly.

​

​

2. Rolling a 401(k) into a Traditional IRA

​

Benefits

• Consolidates accounts — one statement, one RMD calculation, one beneficiary structure

• Dramatically broader investment options (individual stocks, ETFs, bonds, alternatives)

• Typically lower fee structures than employer plans

• Preserves tax-deferred status — no immediate tax due

• Can continue growing tax-deferred indefinitely until RMDs begin

​

Costs & Risks

• Loses the Rule of 55 penalty-free access window (if applicable)

• State-level creditor protection may be weaker than ERISA protection in some states

• If you have significant pre-tax IRA money, it can complicate future Roth conversions (the "pro-rata rule")

• Requires an active decision on investment allocation — inertia is no longer a strategy

​

Tax Implications

• Direct rollover (trustee-to-trustee): zero tax, zero penalty — this is the right mechanism

• Indirect rollover (check made to you): 20% mandatory withholding, 60-day window to redeposit the full amount or face taxes + 10% penalty on the shortfall

• RMDs still begin at 73, taxed as ordinary income

​

Key Decision Point: If you ever want to do Roth conversions, know your pre-tax IRA balance matters. Large traditional rollovers can create pro-rata complications. Plan the sequence carefully.

​

​

3. Rolling a 401(k) into a Roth IRA

​

Benefits

• Future growth is entirely tax-free

• No RMDs — ever (Roth IRAs have no lifetime RMD requirement)

• Tax-free inheritance for heirs (within the 10-year rule under SECURE Act)

• More flexible access to contributions (not earnings) after 5 years

​

Costs & Risks

• The entire converted amount is taxed as ordinary income in the year of conversion

• A large conversion can push you into a significantly higher bracket

• Can trigger IRMAA surcharges on Medicare premiums (if you're 63+, two-year lookback applies)

• May create unexpected state tax liability

• Requires liquidity to pay the tax bill — ideally from non-retirement funds

​

Tax Implications

• This is a taxable event — the pre-tax 401(k) balance becomes ordinary income

• Strategic partial conversions over multiple years often make more sense than a full rollover

• Best done in low-income years (gap between retirement and Social Security/RMDs)

• The "conversion window" — the years between retirement and age 73 — is one of the most valuable tax planning opportunities available

​

Key Decision Point: Don't convert based on emotion ("I hate paying taxes later"). Run the math. Compare your current bracket to your expected bracket in retirement. If they're similar or you expect higher income later, conversion makes sense. If you expect significantly lower income in retirement, it may not.
