If you’ve ever thought about withdrawing money from your retirement account before age 59½, you probably know about the 10% early withdrawal penalty. But there’s an important exception you might not have heard of: Substantially Equal Periodic Payments (SEPP).
SEPP is a special IRS rule that allows you to take early withdrawals from retirement accounts like IRAs or 401(k)s without paying that penalty — as long as you follow certain strict guidelines.
Here’s everything you need to know about SEPP and how it works.
What Exactly Is SEPP?
SEPP stands for Substantially Equal Periodic Payments. It’s an IRS-approved method that lets you set up a schedule of withdrawals from your retirement account that are:
Equal (or nearly equal) in amount
Taken at regular intervals (monthly, quarterly, or yearly)
Continued for a minimum period of time
If you follow the SEPP rules, you can avoid the 10% penalty for early withdrawal, even if you’re younger than 59½.
How Do SEPP Payments Work?
To use SEPP, you must agree to withdraw a specific amount of money at consistent intervals. The key is that your payments must be “substantially equal,” meaning the IRS expects these withdrawals to be steady and predictable.
The payment amount is calculated using one of three IRS-approved methods:
Fixed Amortization Method Payments are based on your life expectancy and a reasonable interest rate, spread evenly over time.
Fixed Annuitization Method This uses an annuity formula, which calculates a fixed payment amount based on your account balance and life expectancy.
Required Minimum Distribution (RMD) Method Payments vary each year based on your account balance and IRS life expectancy tables, similar to how required minimum distributions work after age 72.
You pick the method that best fits your needs, but once you start, you have to stick with the plan.
How Long Do You Have to Take SEPP Withdrawals?
SEPP payments must continue for the longer of:
5 years, or
Until you reach age 59½.
Example 1:
If a taxpayer starts SoSEPP at age 56 on December 1, 2024, they cannot change or stop the payments until December 1, 2029 (five years later), even though they turn 59½ on February 15, 2028.
Example 2:
If the same taxpayer started a different SoSEPP at age 52 on December 1, 2020, they cannot modify or stop payments until February 15, 2028 (the date they turn 59½), even though the five-year period ends on December 1, 2024.
Why Use SEPP?
SEPP can be a great option if:
You want to retire early and need access to your retirement savings.
You have an unexpected financial need but want to avoid penalty fees.
You want a structured way to receive retirement funds before age 59½.
Important Things to Know Before Starting SEPP
Stick to the Payment Schedule: You cannot modify or stop payments without penalty during the required period. If you do, the IRS can charge you the 10% penalty retroactively on all SEPP withdrawals.
Calculations Are Complex: Getting your payment amount right is crucial. A miscalculation could lead to penalties, so it’s wise to consult a financial advisor or tax professional.
Interest Rate Limits Apply: The interest rate used in the fixed amortization or annuitization methods must meet IRS limits (no higher than 5% or 120% of the federal mid-term rate).
Account Balance Matters: Your payment amount is based on your account balance and IRS life expectancy tables, so fluctuations in your investments can affect your withdrawal amounts if you choose the RMD method.
In Summary
SEPP is a powerful but strict rule that allows you to access retirement funds early without penalty—if you commit to taking equal periodic payments over time.
If you’re considering early withdrawals and want to avoid penalties, SEPP could be the right strategy. But because of the complex calculations and strict rules, it’s essential to plan carefully and seek professional guidance.
