You can roll a 401(k) into a SIMPLE IRA, but only pre-tax balances, and only after you have participated in the SIMPLE IRA plan for at least two full years. Moving the money in before that anniversary is the mistake that hurts people: the IRS treats the transfer as a distribution and applies a 25% additional tax on top of ordinary income tax. Everything else about rolling a 401(k) into a SIMPLE IRA follows from that waiting period.
When the Two-Year Clock Starts
A SIMPLE IRA will not accept money from a 401(k), a traditional IRA, or any other non-SIMPLE retirement plan until you have been a participant for two years. The clock starts on the first day your employer deposits any contribution into your SIMPLE IRA, whether that’s your own salary deferral or an employer match or nonelective contribution.1Internal Revenue Service. Retirement Plans FAQs Regarding SIMPLE IRA Plans During those two years, the only rollovers the account can receive are transfers from another SIMPLE IRA.2Internal Revenue Service. SIMPLE IRA Withdrawal and Transfer Rules
Once the two years are up, a qualified plan like a 401(k) can roll pre-tax funds into the account.3Internal Revenue Service. Rollover Chart The rule sits in the tax code at Section 408(p)(1)(B), which limits SIMPLE IRA contributions to salary deferrals until the window described in Section 72(t)(6) has closed.4Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts
To pin down your exact eligibility date, check your first SIMPLE IRA statement or ask your employer’s plan administrator when the initial deposit hit your account. The two-year anniversary of that date is the earliest a 401(k) rollover can land in the account.
The 25% Penalty for Moving Money in Early
If 401(k) money enters your SIMPLE IRA before the two-year period ends, the IRS does not treat it as a rollover. It becomes a taxable distribution from the SIMPLE IRA, and you owe a 25% additional tax on the entire amount. During the two-year window, the usual 10% early distribution penalty is replaced by 25%.2Internal Revenue Service. SIMPLE IRA Withdrawal and Transfer Rules That penalty stacks on top of ordinary income tax, so a premature $50,000 rollover could easily cost $15,000 or more in combined taxes.
The tax code sets this out at Section 72(t)(6): for any amount received from a SIMPLE IRA during the two-year participation period, the 10% additional tax is replaced by 25%.5Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Exceptions apply only if you are at least 59½, disabled, or otherwise qualify for a recognized exemption from the early distribution tax.1Internal Revenue Service. Retirement Plans FAQs Regarding SIMPLE IRA Plans
The money can also be reclassified as an excess contribution, which triggers a separate 6% excise tax for every year the excess remains uncorrected.6Internal Revenue Service. Retirement Topics – IRA Contribution Limits Penalties stack quickly, and they almost always outweigh any benefit from early consolidation.
What Cannot Come Along
Not everything in your 401(k) is eligible for this rollover, even after two years. Designated Roth 401(k) balances cannot be moved into a SIMPLE IRA under any circumstances; the IRS rollover chart marks that transfer as “No.”3Internal Revenue Service. Rollover Chart SIMPLE IRAs also do not accept rollovers from Roth IRAs.2Internal Revenue Service. SIMPLE IRA Withdrawal and Transfer Rules
If your 401(k) contains both pre-tax and Roth money, the rollover has to be split. The pre-tax portion can go to the SIMPLE IRA once the waiting period ends; the Roth portion needs to go to a Roth IRA instead. Ask your 401(k) administrator for a breakdown of pre-tax and Roth balances before initiating any transfer.
Outstanding 401(k) loans also can’t come with you. Rolling an unpaid loan balance into an IRA could disqualify the entire account, and the IRS is explicit about that.7Internal Revenue Service. Retirement Plans FAQs Regarding Loans When you leave an employer with a loan outstanding, the plan typically offsets the unpaid balance against your account, and that offset is treated as a distribution. The practical move is to pay off any 401(k) loan before starting a rollover if you possibly can. If you can’t, plan for the tax hit on the outstanding balance.
Direct Rollover vs. Indirect Rollover
How the money physically moves matters more than most people realize.
A direct rollover, sometimes called a trustee-to-trustee transfer, sends the funds straight from your 401(k) plan to the SIMPLE IRA custodian. The check is made payable to the new custodian for your benefit. No taxes are withheld, and you never touch the money. This is the cleaner path.
An indirect rollover puts the check in your hands first, and that triggers mandatory 20% federal income tax withholding. On an $80,000 balance, you receive a check for $64,000. You then have 60 days to deposit the full $80,000 into the SIMPLE IRA, which means finding $16,000 from other funds to replace what was withheld. If you deposit only the $64,000 you received, the missing $16,000 is treated as a taxable distribution.8Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions The withheld amount comes back as a credit when you file your tax return, but not before.
Miss the 60-day deadline by even a day and the entire amount becomes taxable income for the year, plus the additional tax on early distributions if you are under 59½.9Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans Direct rollovers avoid both traps. If your 401(k) plan insists on mailing the check to you, make sure it is payable to the SIMPLE IRA custodian rather than to you personally, which preserves direct rollover treatment.
What to Do During the Waiting Period
If you just started at a new employer and the SIMPLE IRA is still inside its two-year window, you don’t have to leave your old 401(k) balance behind. A traditional IRA will accept a 401(k) rollover at any time, with no waiting period. You can park the funds there, keep them tax-deferred, and then move them into the SIMPLE IRA once the two-year anniversary passes. The IRS rollover chart confirms that a traditional IRA can roll into a SIMPLE IRA after the two-year period, on the same terms as a 401(k).3Internal Revenue Service. Rollover Chart
The extra step is minor compared to the cost of a premature transfer, and it gives you full control over how the money is invested in the meantime.
Tax Reporting for the Rollover
Even a perfectly executed, tax-free rollover creates paperwork. Your old 401(k) plan issues Form 1099-R reporting the distribution, and your SIMPLE IRA custodian files Form 5498 documenting the incoming rollover contribution.10Internal Revenue Service. Instructions for Forms 1099-R and 5498 Report the rollover on your federal return for the year the distribution occurred even when no tax is owed.
On Form 1040, the full distribution amount from the 1099-R goes on the “Pensions and annuities” line, with the taxable amount listed as zero if the rollover was completed in full. If an indirect rollover fell short (because the 20% withholding was not replaced from other funds, for example), the portion you didn’t redeposit is taxable income for that year and may also trigger the additional tax on early distributions if you are under 59½.8Internal Revenue Service.

Keep copies of both forms along with any transfer confirmation letters from the custodians. The IRS occasionally questions rollovers years later, and the paper trail is the difference between a quick resolution and a drawn-out audit.
