When to Roll Over a Small 401(k) After Changing Jobs

Quick summary

When you leave a job and have a small 401(k) balance, you generally have four choices: leave the money in the old plan (if allowed), roll it into your new employer’s 401(k), roll it into a traditional or Roth IRA, or cash it out. Each choice has trade-offs: tax consequences, fees, investment options, plan rules, and the administrative burden of multiple accounts. Important tax rules to remember: a direct rollover preserves tax deferral; an indirect rollover must be completed in 60 days to avoid taxes and penalties and can trigger mandatory 20% withholding if not handled correctly (see the IRS guidance) (https://www.irs.gov/retirement-plans/plan-participant-employee/rolling-over-your-retirement-plan-account).

In my practice, I see these questions most often from clients with balances between $1,000 and $25,000. Getting the rollover decision right—especially for small accounts—can prevent needless fees and tax leakage that materially reduce long-term retirement outcomes.

Why this matters

Small balances are easy to overlook but can add up. Multiple small 401(k) accounts create friction (separate paperwork, duplicate fees, forgotten accounts) that reduces the benefit of long-term compounding. Choosing the right destination—another 401(k) or an IRA—can lower expenses and provide better investment choices, or preserve creditor protections and access to loans in some employer plans.

Authoritative resources: IRS rollover rules explain the 60-day limit and tax consequences for indirect rollovers (IRS), and the Consumer Financial Protection Bureau explains rollover options and consumer considerations (CFPB) (https://www.consumerfinance.gov/learn/retirement-accounts/401k-rollover/).

Key timing and plan rules to check first

1. Does your former employer allow you to keep a small balance in the plan? Some plans allow former employees to leave accounts in place, others automatically distribute or transfer small balances.
2. Is there a mandatory cashout or automatic IRA rollover policy? Under federal plan rules, many plans treat very small balances differently; some plans automatically move balances in a specified range (commonly documented in the plan’s Summary Plan Description). If your plan forces a distribution or an automatic rollover, you’ll want to act before the process completes if you prefer a different outcome.
3. Will your new employer’s plan accept rollovers? Not all 401(k) plans accept incoming rollovers. Confirm with the new plan administrator.
4. What are the investment options and fees in each destination? Compare expense ratios, administrative fees, and the quality of available funds.

Action: request the plan’s Summary Plan Description (SPD) and distribution rules from your former plan administrator and the rollover acceptance policy from your new plan.

Direct rollover vs indirect rollover: why it matters

• Direct rollover (trustee-to-trustee transfer): The plan sends funds directly to the receiving plan or IRA. This avoids withholding and immediately preserves tax deferral. This is the recommended route for nearly all situations.

• Indirect rollover (distribution paid to you): Your employer issues a check to you. The plan administrator generally must withhold 20% for federal income tax if the distribution is eligible for rollover. You then have 60 days to deposit the full distribution amount (including the withheld 20% you must replace from other funds) into an eligible account to avoid taxes and penalties. Missing the 60-day deadline generally results in the distribution being taxable and possibly subject to the 10% early withdrawal penalty if you’re under 59½. See IRS rules on the 60-day rollover and withholding (https://www.irs.gov/retirement-plans/plan-participant-employee/rolling-over-your-retirement-plan-account).

Practical tip: Always request a direct rollover when possible.

When rolling over makes the most sense

Choose a rollover when one or more of the following apply:

• Fees are higher in the old plan than in an IRA or your new employer plan. Small balances are particularly vulnerable to flat administrative fees that erode returns.
• Investment choices in the old plan are limited or expensive.
• You want fewer accounts to manage—consolidating into one IRA or one employer plan simplifies record-keeping.
• You want access to investments not offered in the old plan (tax-efficient funds, low-cost index funds, ETFs).
• You plan to convert to a Roth and can afford the tax bill; rolling a traditional 401(k) into a Roth IRA triggers income tax on the converted amount.

When NOT to roll over immediately:

• The old plan has exceptionally low fees or institutional-class funds you can’t replicate in an IRA (rare but possible).
• You need access to plan-specific protections (some 401(k) plans offer stronger creditor protection or allow loans while IRAs do not). If creditor protection in bankruptcy is a concern, check plan vs IRA protection for your state and situation.
• The balance is very small and your plan will automatically move it to an IRA that you don’t control; in that case, evaluate that auto-IRA option before acting.

Practical step-by-step checklist to roll over a small 401(k)

1. Get the facts: request the SPD and distribution options from your old plan administrator. Confirm if your old plan has a mandatory distribution policy for small balances.
2. Decide destination: new employer’s 401(k) (if allowed) or a traditional/Roth IRA. Confirm the new plan accepts rollovers, or open an IRA with a low-cost custodian.
3. Prefer a direct rollover: fill out the receiving-plan rollover paperwork and request a trustee-to-trustee transfer.
4. If doing a Roth conversion, calculate the tax impact and consider spreading conversions across years to manage tax brackets.
5. Complete the transfer and confirm funds cleared into the receiving account. Keep the confirmation for tax records.
6. If you receive a check payable to you (indirect rollover), deposit the full amount within 60 days and document the deposit. If 20% was withheld, you’ll need to replace that out of pocket to avoid taxes on the withheld portion.

Common mistakes and tax traps

• Accepting cash-out: If you cash out a small balance while under age 59½, you’ll normally pay ordinary income tax plus a 10% early withdrawal penalty unless an exception applies. Cashing out also eliminates the benefit of tax-deferred growth.

• Doing an indirect rollover without replacing withheld taxes: Many people mistakenly think the withheld amount will be covered by the rollover; it won’t unless you deposit additional funds to make up the shortfall.

• Forgetting plan rules: Some plans automatically roll small balances into an IRA or cash them out. Check plan timelines and act early.

• Not checking for employer match opportunity: If you roll into a new employer plan and you’re still eligible for matching contributions, combining balances can make it easier to track and maximize matches going forward.

Examples from practice

Case 1 — Balance $8,500: Client left a job and the old plan offered only a handful of high-fee funds. We completed a direct rollover to a traditional IRA at a low-cost broker and consolidated two old 401(k) accounts. Result: lower ongoing fees and simpler rebalancing.

Case 2 — Balance $3,200: Client moved to a new employer with a better plan but the old plan had an automatic distribution policy for balances under $5,000. We confirmed the outgoing plan’s timeline and requested the direct rollover to the new plan before the auto-transfer completed.

Case 3 — Balance $12,000, considering Roth conversion: The client had several years of low taxable income ahead; we recommended a partial conversion to a Roth IRA spread over two years to limit tax-bracket impact.

Frequently asked questions

• How long do I have to roll over funds? You generally have 60 days for an indirect rollover; direct rollovers have no 60-day limit because the money never hits your hands (IRS).

• Will my employer withhold taxes on a rollover? For indirect distributions, plans typically withhold 20% for federal taxes. Direct rollovers do not trigger withholding.

• Can I roll multiple small 401(k) accounts into a single IRA? Yes — consolidating old plan balances into a rollover IRA is common and can reduce fees and simplify management. See our related glossary on Rollovers vs Transfers: Avoiding Tax Traps When Changing Employers.

• Are there penalties for rolling over to a Roth? Rolling a pre-tax 401(k) into a Roth IRA triggers ordinary income tax on the converted amount but not the 10% early withdrawal penalty if the transfer is a proper conversion.

Final recommendations

• Default to a direct rollover unless you have a compelling reason not to.
• Compare fees, investment menus, and plan rules before deciding.
• If you plan a Roth conversion, run tax projections so you don’t create an unexpected tax bill.
• Act quickly if your old plan has automatic distribution or transfer rules—these can occur without much notice.
