Moving Money From a Simple IRA to a 401(k): What You Need to Know

Yes, you can roll a Simple IRA into a 401(k), but the rules depend on how long you've had the Simple IRA

A rollover means moving money from one retirement account to another without paying taxes on it at the time of the transfer. You can move a Simple IRA into a 401(k), but there is a waiting period: you must have had the Simple IRA for at least two years before the rollover is allowed. If you try to roll over a Simple IRA into a 401(k) before two years have passed, the IRS treats it as an early withdrawal, and you'll owe income tax plus a 25% penalty on the amount you move.

The two-year clock starts from the date you first contributed to any Simple IRA, not from when you opened each individual account. If you've had a Simple IRA for two years or longer, you can roll the full balance into a 401(k) at your current or new employer, as long as that employer's plan accepts rollovers.

Key Takeaways

You must wait two years from your first Simple IRA contribution before rolling money into a 401(k); rolling over before that triggers a 25% penalty plus income tax.
The two-year period is measured from when you first contributed to any Simple IRA, not from when you opened a specific account.
Your new employer's 401(k) plan must accept rollovers, so confirm this with your plan administrator before you initiate the transfer.
You should use a direct rollover (trustee-to-trustee transfer) rather than taking the money yourself, because a direct rollover avoids withholding and keeps the entire amount tax-deferred.
If you take the money yourself instead of doing a direct rollover, your Simple IRA provider will withhold 20% for taxes, and you have only 60 days to deposit the full amount into the 401(k) or face taxes and penalties on the withheld portion.

The two-year rule and what happens if you roll over too early

The IRS imposes a two-year holding period on Simple IRAs specifically to discourage early withdrawals. This rule applies only to Simple IRAs, not to traditional IRAs or Roth IRAs. The two-year period starts on the date you made your first contribution to a Simple IRA—whether that was a contribution from your employer, a salary deferral from your paycheck, or a rollover from another Simple IRA.

If you roll a Simple IRA into a 401(k) before two years have passed, the IRS treats the rollover as a taxable distribution. You will owe ordinary income tax on the full amount, plus a 25% early withdrawal penalty. This is different from the standard 10% early withdrawal penalty that applies to IRAs before age 59½. The 25% penalty is unique to Simple IRAs and applies regardless of your age.

Example: You opened a Simple IRA on January 15, 2023, and contributed $5,000. On June 1, 2024—less than two years later—you try to roll $5,000 into your new employer's 401(k). The IRS will treat this as a taxable distribution. If you are in the 22% tax bracket, you owe $1,100 in income tax plus $1,250 in penalty, leaving you with $2,650 of the original $5,000.

How to do a direct rollover from Simple IRA to 401(k)

A direct rollover (also called a trustee-to-trustee transfer) is the safest way to move money from a Simple IRA to a 401(k). In a direct rollover, your Simple IRA provider sends the money directly to your 401(k) plan's custodian. You never touch the money, so there is no withholding, no 60-day deadline, and no risk of accidentally triggering a taxable event.

To set up a direct rollover, contact your Simple IRA provider (usually a bank, brokerage, or insurance company) and ask for a rollover request form. You will need to provide the name and account number of your 401(k) plan and the name and address of the 401(k) custodian. Your Simple IRA provider will send the funds directly to the 401(k) custodian, and the transfer typically takes one to two weeks. Once the money arrives in your 401(k), it is subject to that plan's rules—including investment options, withdrawal restrictions, and loan provisions.

Before you initiate the rollover, confirm with your 401(k) plan administrator that the plan accepts rollovers from Simple IRAs. Most employer 401(k) plans do accept them, but some plans restrict rollovers to certain types of accounts or have other conditions. If your plan does not accept Simple IRA rollovers, you will need to keep the Simple IRA or explore other options.

What happens if you do an indirect rollover instead

An indirect rollover means you withdraw the money from your Simple IRA yourself and then deposit it into your 401(k) within 60 days. This method is riskier than a direct rollover because your Simple IRA provider will withhold 20% of the amount for federal income tax. If you do not deposit the full original amount (including the withheld 20%) into the 401(k) within 60 days, the withheld portion is treated as a taxable distribution and you owe the 25% penalty on top of income tax.

Example: Your Simple IRA balance is $10,000. You request a withdrawal, and your provider withholds $2,000 (20%), sending you $8,000. You have 60 days to deposit $10,000 into your 401(k). If you deposit only the $8,000 you received, the $2,000 withheld is treated as a distribution subject to the 25% penalty plus income tax. You would owe $500 in penalty plus income tax on $2,000, even though you never actually received that money.

The 60-day clock starts the day you receive the money, not the day you request the withdrawal. Weekends and holidays count toward the 60 days. If the 60th day falls on a weekend or holiday, you must complete the deposit by the next business day. Missing the deadline by even one day disqualifies the entire transaction from rollover treatment.

Employer 401(k) plans and whether they accept Simple IRA rollovers

Not every 401(k) plan accepts rollovers from Simple IRAs. Some employers restrict rollovers to certain account types, or they may not accept rollovers at all. Before you initiate a rollover, you must confirm with your plan administrator or HR department that your specific 401(k) plan accepts Simple IRA rollovers.

If your employer's 401(k) plan does not accept Simple IRA rollovers, you have other options. You can roll the Simple IRA into a traditional IRA instead, which has no two-year waiting period and no 25% penalty. You can also leave the Simple IRA where it is and continue to contribute to it if you are still self-employed or work for the employer that sponsors the Simple IRA. If you change jobs and your new employer does not sponsor a 401(k), rolling into a traditional IRA is usually the most straightforward path.

Tax treatment after the rollover is complete

Once money is in your 401(k), it follows 401(k) rules, not Simple IRA rules. The money remains tax-deferred, meaning you do not pay income tax on it until you withdraw it. However, 401(k) plans have different withdrawal rules than Simple IRAs. You generally cannot withdraw money from a 401(k) before age 59½ without paying a 10% early withdrawal penalty, unless you meet a narrow exception (such as disability, medical expenses, or a loan provision in your plan).

The 401(k) also has required minimum distributions (RMDs) starting at age 73 (as of 2023, under current law). Simple IRAs also have RMDs, but the calculation may differ. When you roll a Simple IRA into a 401(k), the balance becomes part of your 401(k) RMD calculation going forward.

If your 401(k) plan allows loans, you may be able to borrow against the rolled-over balance. Simple IRAs do not allow loans, so this is a new option available only after the rollover. However, loans must be repaid on a set schedule, and if you leave your job, the loan may become due immediately.

Frequently Asked Questions

What if I've only had my Simple IRA for one year?

You cannot roll it into a 401(k) yet. If you do, the IRS treats it as a taxable distribution and you owe income tax plus a 25% penalty on the full amount. You must wait until two years have passed from your first Simple IRA contribution. After that, you can roll over without penalty.

Can I roll a Simple IRA into a traditional IRA instead of a 401(k)?

Yes. Rolling a Simple IRA into a traditional IRA has no two-year waiting period and no 25% penalty, even if you have had the Simple IRA for less than two years. A traditional IRA accepts rollovers from Simple IRAs at any time. This is often a simpler option if your new employer does not offer a 401(k) or does not accept Simple IRA rollovers.

Do I have to roll over the entire Simple IRA balance, or can I roll over part of it?

You can roll over part of the balance and leave the rest in the Simple IRA. However, the two-year rule applies to the entire Simple IRA, not to individual portions. If you roll over any amount before two years have passed, the entire rollover is treated as a taxable distribution subject to the 25% penalty.

What if my Simple IRA provider charges a fee to do the rollover?

Some providers charge a fee to process a direct rollover or to close the account. This fee comes out of your Simple IRA balance before the transfer, so the amount that arrives in your 401(k) will be reduced. Ask your provider about fees before you request the rollover so you know what to expect.

Can I roll a Simple IRA into a Roth 401(k)?

Yes, but it is treated as a conversion. You will owe income tax on the full amount rolled over in the year of the conversion, even though you are not taking the money out. This is different from a regular rollover, where the money stays tax-deferred. Consult a tax professional before doing a Simple IRA to Roth 401(k) conversion.
