SIMPLE IRA two-year rule
Last updated August 2026
Short answer
The rule is short, easy to state and expensive to discover late, which is the combination that makes it worth a page of its own.
When the clock starts
On the date the first contribution reaches your SIMPLE IRA, whether that was your deferral or the employer's.
It runs for two years from that date, so somebody who joined in September is clear the following September but one year later, not on a January boundary.
It is per participant and per account rather than per plan, so your colleague's clock has nothing to do with yours.
What the penalty actually is
A 25% additional tax on the taxable amount, in place of the usual 10% that applies to early distributions from other accounts.
Ordinary income tax applies on top, exactly as it would elsewhere.
On $20,000 at a 22% marginal rate, that is $4,400 of income tax plus $5,000 rather than $2,000, so the timing decision is worth $3,000.
The rollover restriction
Inside the two years, the only permitted rollover is to another SIMPLE IRA.
Attempting to move the balance to a traditional IRA or a 401(k) is treated as a distribution, which triggers the 25% charge.
After the period ends, all the normal rollover routes open up and the account behaves like any traditional IRA.
Try it in Walnut
Walnut connects to your brokerage and reads a SIMPLE IRA alongside your other accounts, which is where the question of what to move and when starts.
Changing jobs inside the window
Leaving an employer does not end the period. The clock belongs to the account, not to the employment.
The usual answer is to leave the balance where it is and consolidate later, since nothing forces a former employee to move a SIMPLE IRA.
A new employer's SIMPLE IRA starts its own two-year period, so someone moving between small employers can hold two accounts at different stages.
The exceptions still work
The ordinary exceptions to the additional tax apply here too: disability, death, substantially equal periodic payments, certain medical expenses and the rest of the list.
Where one applies, neither the 10% nor the 25% is charged, though income tax still is.
Publication 560 and the IRS exceptions page are the references, and confirming an exception before withdrawing is considerably cheaper than confirming afterwards.
Employer switches and plan terminations
If an employer terminates its SIMPLE IRA, your two-year clock does not reset or accelerate. It runs from your first contribution regardless.
A balance left behind at a former employer keeps running toward the end of its own period, so waiting is usually the cheapest option.
Once the period ends, the account can be consolidated with other IRAs like any traditional IRA, which is when tidying up becomes sensible.

FAQ
What is the SIMPLE IRA two-year rule?
+
During the two years beginning with your first contribution to the plan, a distribution that is not rolled into another SIMPLE IRA is subject to a 25% additional tax rather than the usual 10%, and rollovers to other account types are not permitted.
When does the clock start?
+
On the date the first contribution is deposited into your SIMPLE IRA, not on the plan year, not on your hire date and not on 1 January. Each employee has their own clock.
Does changing jobs restart it?
+
Starting at a new employer with its own SIMPLE IRA begins a new two-year period for that account. The original account keeps its own clock, so two accounts can be at different stages at the same time.
Can I roll it into a 401(k) during the two years?
+
No. Rollovers during the period are limited to another SIMPLE IRA. After two years the balance can move to a traditional IRA, a 401(k) or another eligible plan under the normal rules.
Do the usual exceptions still apply?
+
Yes. The exceptions to the additional tax, such as disability, death and substantially equal periodic payments, apply here too. Where an exception applies, neither the 10% nor the 25% is charged.
How much does getting this wrong cost?
+
On a $20,000 withdrawal at a 22% marginal rate, income tax is $4,400 and the additional tax is $5,000 rather than $2,000. The mistake costs $3,000 more than the same withdrawal from any other retirement account.
Why does this rule exist?
+
SIMPLE plans are cheap to run and easy to join, so the stiffer penalty discourages using them as short-term tax shelters. It is a deterrent aimed at the plan type rather than at any behaviour by the employee.
What should I do if I leave inside the two years?
+
Usually leave the money where it is until the period ends, then roll it out normally. If a rollover cannot wait, moving it to another SIMPLE IRA is the only transfer that avoids the penalty.
Does leaving the employer end the two years?
+
No. The clock belongs to the account rather than to the job, so it keeps running after you leave. Waiting until it expires before consolidating is usually the cheapest course.
