What Should You Do With Your 401(k) When You Retire?

When you retire, one of the most common questions is: “What should I do with my 401(k)?”

The answer depends on your goals, costs, tax strategy, and how much control you want. Let’s break down the basic options and the key factors to consider.

A few Basic 401(k) Options in Retirement

Leave it where it is
If your employer plan allows, you may be able to keep your 401(k) after retirement.

Take a full cash distribution
This typically results in a significant tax liability. Withdrawals are taxed as ordinary income, and if you’re not yet at retirement age, you may also face a 10% penalty.

Roll it into an IRA (Traditional or Roth)
A Traditional IRA rollover is typically tax-free when done correctly as a direct rollover. This is not considered a withdrawal event.
If you have after-tax 401(k) contributions, you may roll them into a Roth IRA.

Keep in mind that you don’t have to choose just one option right away. Many retirees start by leaving funds in a 401(k) for a period of time, then later decide to roll into an IRA once they’ve reviewed their broader retirement picture.

If you opt to roll into an IRA, a common follow-up question is 'what to do with ira after retirement'. This might involve continuing investments, planning strategic withdrawals, or taking advantage of options like Qualified Charitable Distributions for tax-efficient giving.

Key Factors to Consider Before Deciding

Costs

In the past, 401(k)s were often more expensive due to record-keeping and administrative fees, but that’s less common today. Many modern 401(k) plans are more cost-competitive, though it’s still important to review your plan’s fees.
Some plans still carry higher costs, so check your Summary Plan Description or ask HR for a breakdown of total fees.
Pay close attention to the fund options available in your 401(k).

Some 401(k)s include institutional share classes with extremely low expense ratios, often cheaper than what you can get in an IRA. While lower expenses reduce costs, they do not guarantee better performance.
Others may not offer funds with competitive expense ratios.
Beyond expense ratios, mutual funds may also have shareholder fees such as sales loads (front-end or back-end), redemption fees, and account fees for maintenance or inactivity.

Compare this with an IRA:

IRAs may offer low-cost ETFs, mutual funds, or CDs.
Some 401(k)s still have access to institutional share classes that aren’t available in retail IRAs.

If your 401(k) carries higher costs, moving funds to an IRA could be worth exploring. If not, leaving it could be worthwhile.

Fees may feel small at first glance, but over 10–20 years they can eat into your nest egg significantly. That’s why reviewing fee disclosures and understanding expense ratios may be essential before deciding whether to stay in a 401(k) or move funds elsewhere.

Control & Flexibility

401(k): Some plans may feel clunky to manage; limited trading windows, fewer rebalancing options, and sometimes a less user-friendly platform. If it takes a lot of effort to make changes or coordinate your strategy, that may be a drawback.
IRA: IRAs generally provide more flexibility and control, including broader investment options and more flexibility around Roth conversions.

Investment Options

401(k): Usually limited to a curated fund lineup. This can be good (less overwhelming, simpler decisions) if the lineup is strong. For more on building an effective retirement portfolio, see How a Solo Financial Advisor Builds Your Portfolio in Santa Rosa.

IRA: Almost unlimited choices; stocks, bonds, ETFs, CDs, alternative investments. More options = more flexibility, but also more complexity. A financial advisor can help you select investments that align with your goals (What Should I Look For in a Financial Advisor?).

Some 401(k) plans may also provide a brokerage window option. For example, certain 401(k)s at Charles Schwab offer a PCRA (Personal Choice Retirement Account), which allows access to a much wider range of investments (though not every option available in a regular brokerage account. For instance, if your 401(k) offers a stable value fund, the PCRA might not give you the ability to purchase a money market fund instead). Always review your plan’s brochure or documentation carefully to understand what is, and isn’t, available. This is provided as an example of features some 401(k) plans may offer. It’s not a recommendation of any specific provider.

Broader investment choices can be both a blessing and a challenge. While an IRA can open the door to thousands of mutual funds, ETFs, and even alternative investments, it also requires more due diligence. Without a clear investment strategy, too many options may lead to decision fatigue or even costly mistakes. A financial advisor may help you align these choices with your retirement goals.

Consolidation

Many retirees have multiple old 401(k)s scattered across employers.
Consolidating into one IRA or into your current employer’s 401(k) may simplify tracking and rebalancing.

Ease of Use

Some 401(k) providers might offer user-friendly platforms, while others might be difficult to navigate.
IRAs might provide greater ease of use.

Account Coordination

You may want different asset allocations in different accounts based on your overall tax and investment strategy.

Consolidating into an IRA may make coordinating across your portfolio easier. Unless you want to keep access to specific investments or services, consolidating retirement plans may simplify management compared to maintaining multiple accounts.

You may also have the option to consolidate any previous retirement accounts with your current employer’s 401(k), which could help you better monitor and adjust your investments based on your objectives.

Charitable Giving (QCDs)

IRAs allow Qualified Charitable Distributions (QCDs).
If you’re age 70½ or older, you can give directly to charities from your IRA.
QCDs may count toward your RMD and reduce taxable income depending on your tax situation. For planning that integrates charitable giving and Social Security, see No Taxes on Social Security: California & Federal Guide and Ways to Increase Your Social Security Benefit.
This benefit isn’t available from a 401(k).

Required Minimum Distributions (RMDs)

People age 73+ must take RMDs from IRAs.
However, if you’re still working at 73 or older, you don’t have to take RMDs from your current employer’s 401(k).
This makes leaving money in your current 401(k) attractive if you’re working past traditional retirement age.

Planning for RMDs is more than just taking money out. It’s also about thinking through where to withdraw from first; taxable accounts, 401(k), IRA, or Roth. Coordinating these withdrawals may help balance your tax liability, maintain Medicare premium thresholds, and preserve long-term wealth. Planning ahead may help reduce unexpected challenges once RMDs begin.

The Bottom Line

There’s no one-size-fits-all answer.
If your 401(k) has low fees and strong investment options, leaving it could make sense.
If you want greater control, flexibility, easier consolidation, and access to charitable giving with related tax planning opportunities, rolling into an IRA may be the better choice.
A full cash distribution usually increases taxable income, which is why it’s less common as a preferred choice.

The right choice depends on your fees, investment lineup, tax situation, charitable giving goals, and whether you’re still working.

Everyone’s retirement journey is unique. Your decision on what to do with a 401(k) will depend not just on fees and investments, but also on lifestyle, health, legacy planning, and family needs. What works for one retiree may not be the best fit for another. Consider revisiting your strategy every few years, or after major life changes, to make sure your retirement accounts continue working toward your goals.

Ultimately, questions like 'what should you do with 401k when you retire' or 'what should I do with 401k when I retire' highlight the need for a tailored approach to retirement planning.

The considerations above are general in nature. The right approach for your 401(k) depends on your specific financial situation, goals, and tax circumstances.

Key Takeaways

You can leave your 401(k), cash it out (taxable), or roll it into an IRA.
Compare costs: some 401(k)s are expensive, but some offer low-cost institutional funds.
IRAs may provide more flexibility in investments, Roth conversions, and QCDs.
If you’re still working at 73, you may delay RMDs from your current employer’s 401(k).
Consolidation and ease of use are important for managing retirement accounts efficiently.
