7 Costly 72(t) Mistakes That Trigger IRS Penalties
A 72(t) SEPP plan can be a powerful tool for accessing retirement funds early — but it's also one of the most unforgiving areas of tax law. A single mistake can trigger the 10% early withdrawal penalty retroactively on all prior distributions, plus interest. Here are the 7 most costly mistakes to avoid.
Mistake 1: Using the Wrong Interest Rate
For the Fixed Amortization and Fixed Annuitization methods, the IRS limits the interest rate you can use. Using a rate that exceeds 120% of the Federal Mid-Term Rate for the applicable month will invalidate your plan. Always verify the maximum allowable rate before finalizing your calculation.
Mistake 2: Changing the Distribution Amount
Once a 72(t) SEPP plan begins, you cannot change the distribution amount (except for the one-time switch from Fixed Amortization to RMD). Taking more or less than the calculated amount in any year will invalidate the plan and trigger retroactive penalties.
Mistake 3: Rolling Over the Account
Rolling over your SEPP account to another IRA or retirement account is considered a modification and will invalidate your plan. If you need to move accounts, consult your 72(t) consultant before taking any action — there are specific rules about what is and isn't allowed.
Mistake 4: Stopping Distributions Early
You must continue taking distributions for at least 5 years or until you reach age 59½, whichever is longer. Stopping distributions before this period ends — for any reason — will invalidate the plan and trigger retroactive penalties.
Mistake 5: Not Documenting the Plan
The IRS may audit your 72(t) plan years after it begins. Without proper documentation of your calculation methodology, interest rate, and distribution schedule, you may be unable to defend your plan in an audit. A qualified 72(t) consultant will provide comprehensive documentation as part of the plan design process.
Mistakes 6 & 7: DIY Calculations and Ignoring Account Changes
Attempting to calculate your own SEPP distributions without professional guidance is risky — calculation errors are one of the most common causes of plan invalidation. Similarly, ignoring significant account balance changes (due to market losses or gains) without consulting your 72(t) advisor can lead to compliance issues. Work with a qualified consultant from the start and maintain that relationship throughout the plan.
