What happens if I move my SIMPLE IRA into a 401(k) or IRA during the two-year period?

Summary

The IRS treats the move as a withdrawal. During the two years that start when your employer first deposits money in your SIMPLE IRA, you "can only transfer money to another SIMPLE IRA"; send it anywhere else and the whole amount is taxed as income, with a 25% additional tax instead of the usual 10% if you're under 59½ and no exception applies. A trustee-to-trustee transfer into a SIMPLE IRA at another firm stays tax-free. For plan years beginning after December 31, 2023, there is one more way out: if your employer ends the SIMPLE IRA plan and replaces it with a 401(k) or 403(b), the money can go into that plan.

Example: the same $18,000, two different months

Say you're 41, in the 22% federal bracket, and your SIMPLE IRA holds $18,000. You've left the job and want everything in your traditional IRA.

	Moved 20 months after the first deposit	Moved 25 months after the first deposit
Treated as	A withdrawal of $18,000	A tax-free rollover
Federal income tax at 22%	$3,960	$0
Additional tax on early distributions	25% = $4,500	$0
Federal cost	$8,460	$0
California's own additional tax, if you live there	6% = $1,080	$0

The 25% rate is the expensive part: $4,500 on $18,000, against the $1,800 that the usual 10% rate would take from the same amount withdrawn early from a 401(k). Moving five months later removes both the $4,500 and the $3,960 of income tax in this example, because after the two years the move is a rollover, not a withdrawal. California adds its own early-distribution tax of 2½%, and FTB instructions raise it to 6% for a SIMPLE IRA distribution received within two years of first participating.

When the two years start

This is where the IRS's own pages read slightly differently. The SIMPLE IRA withdrawal and transfer rules page says the period begins "when you first participated in your employer's SIMPLE IRA plan." The SIMPLE IRA FAQ is more exact: it "begins on the first day on which your employer deposits contributions in your SIMPLE IRA." The Form 1099-R instructions use the deposit date too. Your first payroll deferral and the employer's first deposit can be days or weeks apart, and the deposit date is the one the custodian's records will show.

The pages don't spell out the closing day. By plain counting, a period that begins March 3, 2025 ends March 2, 2027, so March 3, 2027 would be the first date clear of it. Ask the custodian which date its system uses before you submit anything, and get it in writing. A move completed one day before the period ends is a distribution under the rule above.

The trap in the word "transfer"

A receiving firm may accept a trustee-to-trustee transfer from your SIMPLE IRA into a regular traditional IRA. Nothing about the money's route changes the tax result. The 2026 Form 1099-R instructions tell the sending custodian that it "must report as a taxable distribution in boxes 1 and 2a a trustee-to-trustee transfer from a traditional SIMPLE IRA to a traditional IRA that is not a SIMPLE IRA during the 2-year period." So the form arrives in January showing the full amount as taxable, and the tax return has to match it.

The IRS rollover chart shows the same rule from the other side. In the SIMPLE IRA row, every destination except another SIMPLE IRA is marked "after two years."

If your employer replaces the plan

SECURE 2.0 section 332 changed one case for plan years beginning after December 31, 2023. When an employer terminates its SIMPLE IRA plan and moves to a 401(k) or 403(b), IRS Notice 2024-2 (Q&A G-4) lets a distribution taken within the first two years be rolled into a plan that isn't a SIMPLE IRA "only if" it goes to a 401(k) plan subject to the distribution limits of section 401(k)(2)(B) or a 403(b) plan subject to section 403(b)(11).

That's narrow. The Notice names a 401(k) or a 403(b), not a traditional IRA, and only after the employer has ended the SIMPLE IRA plan. If you still work there and HR announces a switch to a 401(k), ask whether the new plan will accept rollovers from the old SIMPLE IRAs, and in which month.

What you can do inside the two years

You can move the SIMPLE IRA to another SIMPLE IRA, trustee to trustee, without tax. One reason is cost: the SIMPLE IRA your employer chose may carry fund expenses well above what another firm charges for its own SIMPLE IRA. On $18,000, a difference of 0.50 percentage points is $90 a year; the fee calculator runs the same comparison over longer periods. Then, once the two years have passed, the account can move on to a traditional IRA or a new employer's plan like any other rollover.

If you need the money before the period ends, the early withdrawal penalty and its exceptions lists the IRA exceptions that remove the additional tax. They apply to a SIMPLE IRA as well; what the first two years change is the rate. The longer arithmetic of cashing out against rolling over is in how much more tax a cash-out costs.
