When you leave a job or retire, your 401(k) balance doesn't disappear, but you do have to decide what to do with it, and that decision affects your taxes, legal protection, and investment control for years to come. This guide directly compares the five most common paths: leaving it in the former plan, rolling it over to a traditional IRA, converting it to a Roth IRA, moving it to a new employer's 401(k), or using it to purchase a fixed annuity.
Option 1: Leave the money in your former employer's 401(k)
Doing nothing is, technically, a valid option if your balance is above the minimum your plan allows former employees to keep (commonly $7,000). You trigger no tax or penalty by leaving it there, and you keep the strong federal creditor protection ERISA plans carry.
The downside is you remain limited to that specific plan's investment menu, which is usually narrower than an IRA's, and some plans charge higher administrative fees to former employees than to active ones. You can also lose track of the account over time, especially if you change your address or email.
Option 2: Roll over to a traditional IRA
A direct rollover to a traditional IRA triggers no tax because the money remains pre-tax. This route generally gives you a far wider range of investment choices than any 401(k) plan, including index funds, individual stocks, bonds, and annuities, and it usually gives you more control over the fees you pay.
The trade-off is more limited legal protection from creditors outside of bankruptcy, which varies by state. In California, a 401(k) keeps unlimited federal ERISA protection, while an IRA's protection outside bankruptcy depends on state rules and tends to be narrower. A traditional IRA's required minimum distribution (RMD) rules are the same as a 401(k)'s: they begin based on your birth year and retirement age under current federal law.
Option 3: Convert to a Roth IRA
Converting your 401(k) balance to a Roth IRA is a taxable event: you pay income tax that same year on the amount converted, since the money moves from pre-tax to after-tax status. In exchange, that money grows tax-free and qualified withdrawals in retirement are also tax-free.
One major advantage of the Roth IRA is that it carries no RMD during the original owner's lifetime, unlike a 401(k) or traditional IRA. That makes it especially attractive for someone who doesn't need the money to live on and would rather let it grow or pass it on. A Roth IRA's legal protection follows the same limited state-level rules as a traditional IRA.
Availability, cost, benefits, and eligibility vary by person, product, contract, and insurance company, as well as by your service area. Guarantees are subject to the claims-paying ability of the issuing insurance company. Karla Arámburo is not affiliated with or endorsed by Medicare or the federal government.
Option 4: Move it to your new employer's 401(k)
If your new employer accepts incoming rollovers, moving your prior balance into that plan also avoids any tax or penalty, as long as it is a direct rollover. You keep ERISA's unlimited federal protection and simplify your life by consolidating accounts in one place instead of managing several former employers' 401(k)s.
The limitation is the same as with any 401(k): your investment options and fees depend entirely on that specific plan's menu, and not every new employer plan accepts incoming money, so it is worth confirming with HR before starting the process.
Option 5: Use it to purchase a fixed annuity
You can transfer your balance (or part of it) into an IRA holding a fixed annuity, which also triggers no tax when done as a direct rollover. In exchange for giving up some investment flexibility, you get a guaranteed income stream protected from market volatility, which can be valuable if you prioritize certainty over growth.
Fixed annuities usually carry surrender charges if you withdraw the money before a set period, and the investment variety is more limited than an IRA holding traditional funds. Creditor protection follows the rules of the IRA that holds it. You can read our full guide on fixed annuities to understand how their guaranteed rates and surrender charge periods work, without repeating that information here.

How to decide which path to take
There is no single correct answer: the decision depends on your age, your current and future tax bracket, how much you value investment control versus income certainty, and whether you already have a clear plan for using that money. Many people end up combining options, for example rolling most of it into a traditional IRA and using another portion for a fixed annuity to cover essential expenses.
Before deciding, we recommend reviewing our 401(k) rollover checklist, which walks through the exact steps to execute the transfer without costly mistakes, since how you make the move matters as much as where you move it to.

Frequently asked questions
Do I pay taxes when I roll over my 401(k) into a traditional IRA?
No, as long as it is a direct trustee-to-trustee rollover of pre-tax money into a traditional IRA. No taxable event occurs because the money remains pre-tax in the new account.
What happens if the check is paid directly to me instead of the new account?
That is called an indirect rollover. The prior plan generally withholds 20% for federal taxes, and you have 60 days to deposit the full amount (including that 20% out of your own pocket) into the new account, or the IRS treats the undeposited portion as a taxable distribution with a possible penalty.
When does it make sense to convert to a Roth IRA instead of a traditional IRA?
When you expect to be in a higher tax bracket in the future, when you have an unusually low-income year to absorb the conversion tax, or when you prioritize leaving a tax-free inheritance to your beneficiaries.
Can I leave my money in my former employer's 401(k) indefinitely?
Generally yes, if your balance is above a minimum threshold (commonly $7,000), though the plan may limit your investment options and certain services once you are no longer an active employee. Confirm your specific plan's rules before deciding to leave it there.
Does a fixed annuity inside an IRA change the RMD rules?
It does not change the age or general requirement to take RMDs from your pre-tax accounts, but the annuity's guaranteed payment stream can help you meet that requirement predictably each year.
Which option gives me the strongest legal protection from creditors?
401(k) plans, whether your former or new employer's, generally have unlimited federal protection under ERISA. IRAs have limited federal bankruptcy protection and state-level protection that varies; in California, IRA protection outside of bankruptcy is more limited than a 401(k)'s.
Can I combine several of these options with the same balance?
Yes. It is common to split a balance: for example, moving part to a traditional IRA for more investment control, and using another part to purchase a fixed annuity for guaranteed income. You do not have to choose one option for your entire balance.
