Early-retirement withdrawal planning
Rule of 55 vs. 72(t): Two Very Different Ways Early-Retirement Rules Can Matter
If retirement happens before age 59½, the account you use—and what you do with an employer plan before moving it—can affect your available choices.
Quick answer: The Rule of 55 is an exception to the 10% additional tax on early distributions. It covers distributions from the plan of an employer you leave in or after the calendar year you turn 55. Section 72(t) substantially equal periodic payments (SEPP) are a separate exception. They can apply to IRAs, and to plans after you leave the employer, but they lock you into a fixed payment schedule. Neither exception makes a withdrawal tax-free; ordinary income tax still applies.
Side-by-side comparison
| Feature | Rule of 55 | 72(t) / SEPP |
|---|---|---|
| Accounts | Qualified employer plans such as a 401(k) or 403(b), from the employer you separated from. Not IRAs. | IRAs, and employer plans after separation from that employer |
| Age requirement | Separation in or after the calendar year you turn 55. Age 50 for qualified public-safety employees of governmental plans, and certain other exceptions under SECURE 2.0. | None. Can start at any age. |
| Amount | Any amount the plan allows | Fixed by one of three IRS methods |
| Flexibility | Take more or less as needed, within plan rules | Generally cannot change the series until the later of 5 years or age 59½ |
| Penalty if rules are broken | Not applicable | The 10% additional tax applies retroactively to all prior payments, plus interest |
| Main risk | Losing access by rolling the money to an IRA first, or a plan that only allows lump sums | Modifying payments too early; locking in a schedule that later no longer fits |
How the Rule of 55 works
The exception turns on the year you leave the job, not the year you take the money. If you leave in the calendar year you turn 55 or later, distributions from that employer's plan avoid the 10% additional tax, even if you withdraw after you have moved on. Leaving at 54 and waiting until 55 does not qualify. Money in plans from earlier employers does not qualify unless it was rolled into the plan of the employer you are leaving before you separated. Ask your plan administrator whether that is allowed.
The plan's own rules still control access. Some plans allow partial withdrawals or installments after separation. Others allow only a full distribution. If the plan is restrictive, the exception may be less useful than it appears.
How 72(t) payments work
IRS Notice 2022-6 permits three methods for calculating the annual payment:
- Required minimum distribution method: the balance divided by a life-expectancy factor, recalculated each year. Payments change with the account value.
- Fixed amortization method: the balance amortized over life expectancy at a chosen interest rate. The payment is fixed.
- Fixed annuitization method: the balance divided by an annuity factor. The payment is fixed.
For the fixed methods, the interest rate can be up to the greater of 5% or 120% of the federal mid-term rate for either of the two months before the first payment. A one-time switch from a fixed method to the RMD method is allowed and is not treated as a modification.
| Method | Assumptions | Approximate annual payment |
|---|---|---|
| RMD method | $500,000 ÷ 31.6 (IRS Single Life Table factor at 55) | $15,800 |
| Fixed amortization | 31.6 years at 5.0% | $31,800 |
| Fixed amortization | 31.6 years at 4.5% | $30,000 |
Hypothetical These figures illustrate how much the method choice matters. They are not a recommendation. Actual calculations depend on the account balance and valuation date, the table used and the applicable federal rate. Because one mistake can trigger retroactive penalties, people often have a tax professional run and document the calculation.
Why the order of steps matters
Someone leaving work at 57 might be tempted to roll the 401(k) into an IRA right away. If they will need money before 59½, that rollover can remove the simpler Rule of 55 option and leave only 72(t), with its rigid schedule. A common sequence is:
- Confirm your separation date relative to the calendar year you turn 55.
- Read the plan's distribution options after separation.
- Estimate how much you need before 59½, and from which accounts.
- Consider leaving enough in the employer plan to cover that need, or a partial rollover if the plan allows.
- Only then decide what to do with the rest.

Other exceptions to know about
The IRS lists other exceptions to the 10% additional tax, including disability, certain unreimbursed medical expenses, and distributions after death. SECURE 2.0 added several more, such as up to $1,000 per year for emergency personal expenses and penalty-free distributions for terminal illness. Some apply only to IRAs, some only to plans. Check the IRS exceptions chart before relying on any of them.
Common mistakes
- Rolling the employer plan into an IRA before checking whether the Rule of 55 is needed.
- Leaving the job in the year before turning 55.
- Assuming old employer plans qualify. Only the plan of the employer you leave counts.
- Taking an extra withdrawal from an IRA that is paying a 72(t) series, which can bust the series.
Frequently asked questions
Does the Rule of 55 apply to IRAs?
No. The age-55 separation-from-service exception applies to qualified employer plans, such as a 401(k), not to IRAs. Rolling the money to an IRA generally gives up that exception.
If I retire at 54, can I use the Rule of 55 when I turn 55?
No. You must separate from service in or after the calendar year you reach 55. Leaving earlier does not qualify, even if you wait to withdraw.
Can I stop 72(t) payments early?
Changing or stopping the series before the later of five years or age 59½ is generally a modification. The 10% additional tax then applies to all prior payments, plus interest, unless an exception such as death or disability applies.
Are withdrawals under either rule tax-free?
No. Both rules only avoid the 10% additional tax. Pre-tax amounts are still subject to ordinary income tax, and withdrawals can affect Marketplace premium tax credits.
