401(k) Rollover to IRA: Avoid the $10,000 Tax Mistake

Rolling over your 401(k) to an IRA protects your retirement savings from taxes and penalties—but only when you handle it correctly. You have 60 days to complete an indirect rollover or you’ll face taxes plus a 10% penalty on the entire amount.

What Is a 401(k) Rollover?

A 401(k) rollover means moving money from your employer-sponsored retirement plan into an Individual Retirement Account (IRA). You’re transferring your savings from one tax-advantaged account to another without triggering taxes or penalties when done correctly.

People typically roll over their 401(k) when they leave a job, retire, or want better investment options than their employer plan offers. The rollover preserves the tax-deferred status of your retirement savings while giving you more control over your money.

Why Roll Over Your 401(k) to an IRA?

Moving your 401(k) to an IRA gives you significant advantages over leaving money in your old employer’s plan.

More Investment Choices

Your 401(k) typically offers 10-30 investment options chosen by your employer. An IRA gives you access to thousands of stocks, bonds, ETFs, mutual funds, and other investments. You can build a personalized portfolio that matches your exact risk tolerance and retirement timeline.

A typical 401(k) might offer three target-date funds and a dozen stock and bond funds. The same money in an IRA lets you buy individual stocks, real estate investment trusts (REITs), international funds, and sector-specific investments your 401(k) never offered.

Lower Fees

Many 401(k) plans charge administrative fees of 0.5% to 2% annually. These fees compound against you over decades, costing you thousands in lost growth. IRAs typically have lower or zero administrative fees—you only pay the expense ratios on your investments.

A $100,000 account paying 1.5% in 401(k) fees versus 0.5% in IRA fees costs you over $30,000 in 30 years assuming 7% returns. That’s $30,000 less in retirement because of fees alone.

Simplified Account Management

Most people change jobs 5-7 times during their career. Each job potentially means another 401(k) account. Rolling old 401(k)s into a single IRA consolidates your retirement savings, making it easier to track performance, rebalance your portfolio, and manage your overall asset allocation.

Fewer accounts mean fewer login credentials to remember, fewer statements to review, and simpler tax reporting. You can see your entire retirement picture in one place.

Better Withdrawal Rules

IRAs offer more flexible withdrawal options than 401(k)s. You can set up systematic withdrawals at any frequency you want, take partial withdrawals easily, and avoid restrictive 401(k) distribution rules. Some 401(k)s only allow annual withdrawals or force you to take your entire balance at once.

Direct vs. Indirect Rollover: Know the Difference

You have two methods for rolling over your 401(k), and the method you choose dramatically affects your taxes.

Direct Rollover (Best Option)

Your 401(k) administrator sends your money straight to your IRA custodian. You never touch the money. No taxes are withheld. No deadlines to meet. No risk of penalties.

Request a direct rollover by telling your 401(k) provider to make the check payable to your IRA custodian “FBO [Your Name]” (For Benefit Of). The check goes directly to Fidelity, Vanguard, Schwab, or wherever your IRA is held.

Indirect Rollover (Risky Method)

Your 401(k) administrator sends you a check. You deposit it into your IRA within 60 days. Your employer must withhold 20% for federal taxes, meaning you only receive 80% of your balance.

If you want to roll over your full balance, you must replace the 20% withheld from other funds. Miss the 60-day deadline or fail to replace the withheld amount, and you’ll owe income taxes plus a 10% penalty on the shortfall.

Example: Why Direct Beats Indirect

Sarah has $50,000 in her old 401(k). With a direct rollover, all $50,000 moves to her IRA tax-free.

With an indirect rollover, Sarah receives a check for $40,000 ($50,000 minus $10,000 in mandatory 20% withholding). She must find $10,000 from her savings to roll over the full $50,000 within 60 days. If she only rolls over the $40,000 she received, she’ll pay income taxes plus a 10% penalty on the $10,000 shortfall—costing her $3,400 in her 24% tax bracket.

Step-by-Step Rollover Process

Follow these steps to roll over your 401(k) correctly and avoid taxes.

Step 1: Choose Your IRA Provider

Select a brokerage firm to hold your IRA. Popular options include Fidelity, Vanguard, Schwab, TD Ameritrade, and E*TRADE. Compare fees, investment options, customer service, and online tools.

Look for providers offering zero account fees, commission-free stock and ETF trades, and a wide selection of no-load mutual funds. Most major brokerages now offer these features.

Step 2: Open Your Rollover IRA

Complete an application with your chosen IRA provider. You’ll need your Social Security number, birth date, employment information, and bank account details. The application takes 10-15 minutes online.

Specify that you’re opening a Rollover IRA (also called a Traditional IRA). If your 401(k) includes Roth contributions, you’ll need to open a Roth IRA separately for those funds.

Step 3: Request Direct Rollover from Your 401(k)

Contact your 401(k) plan administrator (the company that manages your retirement plan, not your employer). Request a direct rollover distribution. They’ll send you paperwork to complete.

Provide your IRA custodian’s name, address, and your IRA account number. Tell them to make the check payable to “[IRA Custodian] FBO [Your Name], Account #[Your IRA Account Number].”

Step 4: Wait for the Transfer

Your 401(k) administrator typically processes rollovers within 2-4 weeks. They’ll mail a check directly to your IRA custodian or send the money electronically. You might receive notification when the transfer starts and completes.

Don’t worry if this takes time. Direct rollovers have no deadline—the money can spend months in transit without tax consequences.

Step 5: Invest Your Rollover Funds

Once your money arrives in your IRA, it sits in a money market settlement fund until you invest it. Log into your IRA account and select investments. Don’t let your money sit uninvested—you’re missing potential growth.

Many people choose a target-date fund matching their expected retirement year. These funds automatically adjust from aggressive to conservative as you age.

Common Rollover Mistakes That Cost Thousands

Avoid these errors that trap people every year.

Taking an Indirect Rollover Unnecessarily

Direct rollovers eliminate all risk. Indirect rollovers create unnecessary complications, withholding headaches, and potential penalties. Always choose direct unless absolutely impossible.

Some people take indirect rollovers because they don’t understand the difference. Others want temporary access to their money. Neither reason justifies the risks involved.

Missing the 60-Day Deadline

Life happens. You receive the indirect rollover check, intend to deposit it, and forget. Day 61 arrives and your entire distribution becomes taxable plus penalties.

The IRS sometimes grants deadline extensions for circumstances beyond your control—medical emergencies, natural disasters, postal errors. But you’re better off avoiding the problem by using direct rollovers.

Forgetting About the 20% Withholding

People doing indirect rollovers often forget they need to replace the 20% withheld. They deposit only the 80% they received, then get shocked by taxes and penalties on the shortfall.

If you receive a $40,000 check from a $50,000 401(k), you must add $10,000 from other sources to complete a full rollover. That withheld $10,000 comes back when you file your tax return—but only if you rolled over the full amount.

Rolling Pre-Tax and Roth Money Together

Your 401(k) might contain both pre-tax traditional contributions and after-tax Roth contributions. These must roll into separate IRAs—traditional money to a Traditional IRA, Roth money to a Roth IRA.

Mixing them creates tax reporting nightmares. Your 401(k) statement shows your traditional and Roth balances separately. Tell your administrator you need two separate checks for two separate IRAs.

Cashing Out Instead of Rolling Over

The worst mistake is taking your 401(k) as cash instead of rolling it over. You’ll lose 20% to withholding, pay income taxes on the full amount, and get hit with a 10% early withdrawal penalty if you’re under 59½.

A $50,000 cash-out costs you $10,000 in withholding, plus $12,000 in income taxes (24% bracket), plus $5,000 in penalties. You keep only $28,000 of your $50,000. That same money rolled over to an IRA keeps the full $50,000 growing tax-deferred.

Special Rollover Rules You Need to Know

Several important rules govern what you can and cannot do with rollovers.

The One-Rollover-Per-Year Rule

You can only do one IRA-to-IRA indirect rollover within any 12-month period. This limit applies across all your IRAs combined—traditional, Roth, SEP, and SIMPLE IRAs count as one big pool.

Direct trustee-to-trustee transfers don’t count against this limit. Neither do 401(k)-to-IRA rollovers. The rule only affects IRA-to-IRA indirect rollovers where you receive a check made out to you personally.

Required Minimum Distributions Cannot Be Rolled Over

Once you turn 73, you must take Required Minimum Distributions (RMDs) from traditional 401(k)s and IRAs. You cannot roll over your RMD amount—that money must come out and get taxed.

Calculate your RMD for the year before doing any rollovers. Take your RMD first, then roll over the remaining balance. Rolling over your RMD by mistake creates tax complications.

Loans From Your 401(k) Become Taxable

If you have an outstanding 401(k) loan when you leave your job, you typically must repay it within 60 days. Fail to repay it and the loan balance becomes a taxable distribution plus potential penalties.

You can roll over the loan balance to your IRA if you have cash to replace the loan amount. This preserves the tax-deferred status. Otherwise, you’ll owe taxes on the loan balance.

Employer Stock Gets Special Treatment

If your 401(k) holds company stock that’s appreciated significantly, don’t automatically roll it to an IRA. Net Unrealized Appreciation (NUA) rules let you transfer appreciated stock to a taxable account and pay only capital gains tax on the appreciation later.

This strategy can save tens of thousands in taxes for people with highly appreciated employer stock. Consult a tax advisor before rolling over a 401(k) containing employer stock worth more than you paid for it.

Alternatives to Rolling Over

Rolling over isn’t your only option when you leave a job.

Leave Money in Your Old 401(k)

If your balance exceeds $5,000, most plans let you leave your money where it is. This works if you’re happy with the investment options and fees are reasonable.

You might keep money in your old 401(k) if it offers unique investments you can’t get elsewhere—like a stable value fund or institutional share class mutual funds with rock-bottom fees.

Roll to Your New Employer’s 401(k)

If your new job offers a 401(k), you can roll your old 401(k) directly into it. This consolidates your retirement savings and might give you access to better investments or lower fees than an IRA.

Some employer plans offer benefits you can’t get in an IRA, like loans, penalty-free withdrawals after age 55 (if you retire or lose your job), and stronger creditor protection in some states.

Partial Rollovers

You can roll over part of your 401(k) and take the rest as cash. This flexibility lets you access money you need now while preserving most of your retirement savings.

You’ll owe taxes and potentially penalties on the cash portion. The rolled-over portion remains tax-deferred. Calculate carefully whether the taxes and penalties justify taking cash now.

Tax Reporting for Rollovers

Your 401(k) administrator sends you Form 1099-R showing your distribution. Your IRA custodian sends Form 5498 showing your rollover contribution. Both forms go to the IRS automatically.

Report the rollover on Form 1040 even though it’s not taxable. The IRS needs to match the distribution reported by your 401(k) with the contribution reported by your IRA. Properly completed, this shows a non-taxable rollover.

Mistakes on these forms happen frequently. Verify the amounts match and the rollover codes are correct. Code “G” on Form 1099-R indicates a direct rollover. Code “1” indicates a normal distribution that might be a rollover—you must report it correctly to avoid taxation.

Rollover Timeline: What to Expect

Week 1: Open your IRA and request rollover paperwork from your 401(k) administrator.

Week 2-3: Complete and submit rollover paperwork. Your 401(k) processes the request.

Week 4-6: Your 401(k) liquidates investments and generates a check or electronic transfer.

Week 7-8: Your IRA receives the funds. You can now invest the money.

Total timeline: 6-8 weeks for most rollovers. Some take longer if your 401(k) only processes distributions monthly or quarterly. Stay patient and check status regularly.

When to Use a Financial Advisor

Most rollovers are straightforward enough to handle yourself. Consider hiring professional help when:

Your 401(k) exceeds $500,000 and you want sophisticated investment management.

You have highly appreciated company stock and need NUA analysis.

You’re retiring within 5 years and need comprehensive retirement income planning.

Your 401(k) includes unusual investments like private equity or hedge funds.

You have multiple old 401(k)s and want help consolidating efficiently.

Fee-only financial advisors charge flat fees or hourly rates without selling products. This eliminates conflicts of interest and ensures advice serves your interests.

State Tax Considerations

Most states follow federal tax rules for rollovers—direct rollovers are tax-free and indirect rollovers have the same consequences as federal law.

A few states impose withholding on indirect rollovers or have special rules for distributions. California, New York, and Massachusetts residents should verify state rules before choosing indirect rollovers.

If you’re moving to a different state during the rollover process, research both states’ rules. Timing your rollover to occur after you establish residency in a lower-tax state can save money on indirect rollovers.

Final Thoughts on 401(k) Rollovers

Rolling over your 401(k) to an IRA gives you control over your retirement savings. You get better investment choices, lower fees, and easier account management. The process takes 6-8 weeks but protects your savings from taxes and penalties.

Always choose direct rollovers over indirect rollovers. Direct rollovers eliminate withholding, deadlines, and penalty risks. The minor convenience of receiving a check yourself isn’t worth the $10,000+ you might lose to taxes and penalties.

Review your investment options before rolling over. Sometimes your 401(k) offers better investments or lower fees than an IRA can provide. Don’t automatically assume an IRA is always better—compare your specific situation.


Frequently Asked Questions

How long does a 401(k) rollover take to complete?

Most 401(k) rollovers take 6-8 weeks from start to finish. You’ll spend 1-2 weeks opening your IRA and requesting rollover paperwork, 2-3 weeks while your 401(k) processes the request, and 2-4 weeks for the actual transfer. Some plans only process distributions monthly, which can extend the timeline. Track your rollover by contacting both your 401(k) administrator and IRA custodian if more than 8 weeks pass without completion.

Can I roll over my 401(k) while still employed?

Most employer 401(k) plans don’t allow in-service rollovers before age 59½. You typically must separate from your employer, reach 59½, or meet specific plan criteria to roll over your 401(k) while still working. Some plans allow rolling over employer contributions (but not employee contributions) after a certain period. Check your specific plan rules—call your HR department or 401(k) administrator to ask about in-service withdrawal options.

What happens to my 401(k) loan when I roll over?

Outstanding 401(k) loans typically must be repaid within 60-90 days when you leave your job. If you don’t repay the loan, the unpaid balance becomes a taxable distribution and you’ll owe income taxes plus a 10% penalty if you’re under 59½. You can roll over the loan amount by contributing equivalent cash to your IRA within 60 days, preserving the tax-deferred status. The repaid loan amount counts toward your rollover total.

Should I roll my Roth 401(k) to a Roth IRA?

Rolling a Roth 401(k) to a Roth IRA makes sense for most people. Roth IRAs have no Required Minimum Distributions during your lifetime, while Roth 401(k)s require RMDs starting at age 73. Roth IRAs also offer more investment options and typically lower fees. The 5-year clock for tax-free withdrawals starts from your first Roth IRA contribution, not the rollover date, so existing Roth IRA owners can access rolled-over funds sooner.

Can I roll over only part of my 401(k)?

Yes, you can do a partial rollover of your 401(k). Roll over the amount you want to keep tax-deferred and take the rest as a distribution. You’ll owe income taxes and potentially penalties on the distributed portion. Partial rollovers make sense when you need some cash now but want to preserve most of your retirement savings. The rolled-over portion remains tax-deferred and the cash portion appears on your tax return as taxable income.
