Quick answer: Ask your old plan for a direct rollover, where the money goes straight from your old 401(k) to your new employer's plan or to an IRA. No taxes are withheld and nothing counts as income. Avoid taking a check made out to you: the plan must hold back 20%, and you have only 60 days to put the full amount back.↗ Share on X

To move retirement savings from one employer to another without paying taxes, ask your old 401(k) plan for a direct rollover (also called a trustee-to-trustee transfer). The money goes straight from the old plan to your new employer's plan or to an IRA (Individual Retirement Account). Because you never touch the cash, no tax is withheld and it does not count as income. The move that causes trouble is taking a check made out to you: the plan must keep 20% for taxes, and you have just 60 days to deposit the full amount somewhere else.

Below are your four choices, the exact steps for a clean rollover, and the mistakes that turn a simple move into a tax bill.

When you leave a job, the money in that employer's plan does not disappear. You usually have four choices:

Cashing out is the option that costs most people the most. A $20,000 balance can shrink by thousands after income tax and the early withdrawal penalty. You also lose the years of growth that money would have had.

How does a direct rollover work, step by step?

Here is the process most people follow. It usually takes one to three weeks.

1. Decide where the money will go. Your new employer's 401(k) or an IRA. If it's the new plan, ask HR or the plan website if they "accept incoming rollovers."

2. Open the receiving account first. If you choose an IRA, open it before you call the old plan. Pick the type that matches your money: a traditional IRA for pre-tax money, a Roth IRA for Roth 401(k) money.

3. Get the receiving account details. You need the account number, the exact name to write on the check ("payable to"), and the mailing address. The new provider usually has a rollover page with this information.

4. Contact your old plan. Call the number on your statement or log in to the website. Say you want a "direct rollover." Many plans let you do it online.

5. Confirm how the check is made out. For a direct rollover, the check (or electronic transfer) is payable to the new provider "for the benefit of" (FBO) you. If the check is made out to you personally, stop and ask: that may be treated as an indirect rollover.

6. Forward the check if needed. Some plans mail the check to you even in a direct rollover. That is fine, as long as it is payable to the new provider. Send it on right away.

7. Check that the money arrived. Log in to the new account. The money may sit in cash at first. You need to choose investments yourself; many people forget this step and leave the money uninvested for months.

8. Keep the paperwork. Save the confirmation letters. Next year you will get a Form 1099-R, and you report the rollover on your tax return.

What is the 60-day rule, and why is it a trap?

If the old plan pays the money to you instead of to the new account, it is called an indirect rollover. The rules are strict:

• The plan must withhold 20% for federal taxes before sending you the check.
• You have 60 days to deposit the money into another retirement account.
• To avoid taxes on the full amount, you must deposit 100% of the original balance, including the 20% the plan kept. That 20% has to come from your own pocket.
• If you deposit less, the missing part counts as income. If you are under 59½, it may also get the 10% penalty.

Simple example: you have $10,000. The plan sends you a check for $8,000 and sends $2,000 to the IRS. To finish the rollover, you must deposit $10,000 within 60 days, using $2,000 of your own savings. You get the $2,000 back as a refund when you file your taxes. If you only deposit the $8,000, the $2,000 is treated as a withdrawal.

This is why a direct rollover is the safer path for most people.

Which account types can you combine?

The tax type of your money has to match, or you create a tax bill.

Many statements show the different "sources" of money. Look for words like "pre-tax," "Roth," or "after-tax" and ask the plan to split the rollover if you have more than one.

When could leaving the money in the old plan make sense?

A rollover is not always the best move. Leaving your savings where they are can make sense when:

• The old plan has very low fees or funds you cannot get elsewhere.
• You left the job in or after the year you turned 55. Many 401(k) plans let you take money out without the 10% penalty in that case (often called the "rule of 55"). That rule generally does not apply once the money is in an IRA.
• You might want a "backdoor" Roth IRA later. Having a large traditional IRA balance can make that strategy taxable. Keeping pre-tax money in a 401(k) avoids the problem.
• You need stronger protection from creditors, which can differ between 401(k) plans and IRAs depending on your state.

If any of these apply to you, it is worth talking to a tax professional or a fee-only financial planner before you move the money.

What mistakes cost people the most?

1. Cashing out small balances. It feels like "only" $3,000, but after taxes and penalty, you may keep much less, and you lose the growth.

2. Letting the check sit. A check made out to you starts the 60-day clock. Miss it and the money is taxed.

3. Forgetting the 401(k) loan. Many plans make the loan due soon after you leave. An unpaid loan can be treated as a withdrawal. Ask the plan what happens and what your deadline is.

4. Leaving the money in cash. After the rollover, choose investments. Uninvested money does not grow.

5. Losing track of old accounts. If you leave the money, update your address and email with the plan, and keep a list of every account you have.

6. Company stock in the 401(k). If you hold your employer's shares, there is a special tax treatment that a normal rollover can wipe out. Talk to a tax professional before you move it.

Do you need a professional?

For a simple pre-tax 401(k) going to a new pre-tax 401(k) or traditional IRA, most people can do it alone by following the steps above. Get help from a CPA, an enrolled agent, or a fee-only planner when:

• You have after-tax money, company stock, or a loan you cannot repay.
• You are thinking about converting pre-tax money to Roth.
• You are close to retirement or already taking withdrawals.
• The amount is large and a mistake would hurt.

A one-time consultation usually costs far less than the taxes from a wrong move.

Your next step today

Find your latest statement from the old 401(k). Write down three things: the balance, the types of money (pre-tax, Roth, after-tax), and whether you have a loan. Then decide where the money will go and open that account if it doesn't exist yet. Only after that, call the old plan and ask for a direct rollover payable to the new provider. Don't accept a check in your own name.

FAQ

Do I have to move my 401(k) when I leave a job?

Not always. If your balance is above the plan's minimum (often $7,000), you can usually leave it where it is. Smaller balances may be cashed out or moved to an IRA by the plan automatically, so read the notice the plan sends you.

Will a direct rollover show up on my taxes?

Yes, you will get a Form 1099-R, and you report the rollover on your tax return. A direct rollover between the same type of account (pre-tax to pre-tax, Roth to Roth) is normally not taxable, and the form will show a code for a direct rollover.

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

Many plans make the remaining loan due soon after you leave. If you don't repay it, the unpaid amount is treated as a distribution, which can mean income tax and a 10% penalty if you are under 59½. You can often avoid that by rolling the same amount into an IRA by your tax filing deadline, including extensions. Ask the plan for its exact rules.
