The main pro of the Rule of 55 is simple: if you leave your employer during or after the calendar year you turn 55, you can withdraw from that employer’s 401(k) or 403(b) without the 10% federal early withdrawal penalty (and, in California, without the 2.5% state penalty). The main cons are that every pre-tax dollar you take out is still taxed as ordinary income, the rule does not cover IRAs or plans from earlier jobs, and your plan may limit how and when you can withdraw.
For a family earning $750,000 or more, that means the Rule of 55 is a penalty exception, not a cheap source of cash. Whether it helps depends on which year you draw, what else you could sell instead, and whether your plan lets you take partial withdrawals.
How the Rule of 55 works in one paragraph
The IRS exceptions table waives the 10% additional tax on qualified plan distributions when “the employee separates from service during or after the year the employee reaches age 55” (age 50 for public safety employees in governmental plans). The same table marks the exception as not available for IRAs. California charges its own 2.5% additional tax on early distributions (FTB 3805P, 2025), and the form’s instructions list the same situation as exception 01 (FTB 3805P instructions, 2025). The reason you leave does not matter: retiring, quitting and being laid off all count.
Rule of 55 pros and cons at a glance
| Pros | Cons |
|---|---|
| No 10% federal penalty and no 2.5% California penalty on withdrawals from the plan you leave | Pre-tax withdrawals are ordinary income, taxed at your top federal bracket and, in California, at full state rates |
| Flexible amounts, if your plan allows partial withdrawals | Some plans allow only a lump sum or fixed installments after separation |
| You can take a new job later and keep drawing from the old plan | Covers only the plan of the employer you just left; IRAs and older 401(k)s are excluded |
| Can use low-income years between leaving work and the start of required minimum distributions | Rolling to an IRA at separation, a common default, removes the exception |
| Much more flexible than 72(t) substantially equal payments | Money you withdraw stops growing tax-deferred, and 20% federal withholding generally applies to each payout made to you |
Why the pros and cons look different at a $750,000+ income
Most articles on this rule picture a retiree with grown children. The families we work with look different: an Amazon executive, a Genentech scientist or a physician who steps back at 55, children still in elementary school, and often a spouse who keeps working. For them the question is rarely “can I get the money out?” It is “which account should pay for the next four and a half years until 59½, and in which calendar year?”
That changes how the cons weigh. A retiree with little other income may pull 401(k) money at the 12% or 22% federal rate. A household with a working spouse earning $350,000 starts much higher, so each 401(k) dollar can land in the 24% or 32% bracket before state tax. Meanwhile a taxable brokerage account full of old RSU shares may be cheaper to draw from, because only the gain is taxed.
Worked example: three ways to fund $150,000 in 2027
Assumptions (illustrative): Priya turns 55 in 2026 and leaves her biotech job in June 2026 with a $1.4 million pre-tax 401(k) and a $900,000 brokerage account. Her husband Alex keeps working at $350,000 and defers $24,500 to his 401(k) (the 2026 limit). Their children are 7 and 10. They live in California, file jointly, take the standard deduction ($32,200 for 2026) and need $150,000 from savings in 2027. 2026 federal brackets are used for 2027 because 2027 figures are not yet published, and California’s 2025 schedule is the latest the FTB has released.
Their federal taxable income before any withdrawal is $293,300 ($350,000 minus $24,500 minus $32,200).
| A: 401(k) under the Rule of 55 | B: same withdrawal after rolling to an IRA | C: sell brokerage shares ($50,000 basis) | |
|---|---|---|---|
| Amount added to taxable income | $150,000 ordinary income | $150,000 ordinary income | $100,000 long-term gain |
| Federal income tax | $39,180 | $39,180 | $15,000 |
| Net investment income tax (3.8%) | $0 | $0 | $3,800 |
| Early withdrawal penalties | $0 | $18,750 | $0 |
| California income tax (9.3%) | $13,950 | $13,950 | $9,300 |
| Total tax on $150,000 | $53,130 | $71,880 | $28,100 |
How the numbers work. In A, the first $110,250 fills the rest of the 24% bracket, which ends at $403,550 of taxable income for 2026, and the remaining $39,750 is taxed at 32%. In B, the IRA does not qualify for the Rule of 55, so Priya adds a 10% federal penalty ($15,000) and California’s 2.5% penalty ($3,750). In C, the $100,000 gain stays in the 15% long-term capital gains rate (which runs to $613,700 of taxable income for joint filers in 2026), and because their modified AGI is above $250,000, the 3.8% net investment income tax applies. California taxes gains at the same rates as wages, and the 9.3% bracket runs from $145,448 to $742,958 for joint filers on the 2025 schedule.
The lesson is not “never use the Rule of 55.” It is that the rule’s pro (option A beats option B by $18,750) only matters once you have decided the 401(k) is the right account to draw. In this example, the brokerage account is cheaper this year. The 401(k) can become the better source in years when household income drops, for example after Alex also stops working, when the same $150,000 could sit largely in the 12% and 22% brackets instead of 24% and 32%.
California versus Washington
California: there is no lower state rate for capital gains, so the state gap between A and C comes only from the smaller taxable amount in C. SDI is a wage tax and does not apply to plan withdrawals.
Washington: a 401(k) withdrawal carries no state income tax in 2026 or 2027, and retirement accounts are exempt from the state’s 7% capital gains tax. The $100,000 gain in option C is also below Washington’s capital gains standard deduction ($278,000 for 2025, the latest published), so it would owe no state tax either. For a Washington family the comparison is purely federal. Note that Washington enacted a 9.9% income tax on AGI over $1,000,000 starting January 1, 2028 (WA DOR), which matters if a large withdrawal lands in 2028 or later.
The decision the family actually has to make
Before giving notice, answer four questions:
- Does the timing qualify? Separation must fall in or after the calendar year you turn 55. Leaving in December of the year you turn 54 does not qualify, even if you wait to withdraw.
- What does the plan allow? Ask the administrator whether partial withdrawals are allowed after separation, how often, and whether the rest can stay invested. A plan that forces a lump sum turns most of the pros into cons.
- Should old plans be rolled in first? If your current plan accepts roll-ins, moving an earlier 401(k) into it before you leave brings that money under the rule. Rolling out to an IRA does the opposite.
- Which account pays for which year? Map spouse income, final RSU vests, bonus and any deferred compensation payouts by calendar year, then choose between 401(k), brokerage and cash for each year. See mega backdoor Roth versus brokerage for how after-tax and Roth money fits into the same bridge.
Common mistakes
- Rolling everything to an IRA on the way out. It is the most common way to lose the exception.
- Treating a Roth 401(k) withdrawal as tax-free. The Rule of 55 removes the penalty only. Before 59½, the earnings portion of a Roth 401(k) withdrawal is generally not a qualified distribution and is taxable.
- Underpaying because of withholding. Plan distributions paid to you carry mandatory 20% federal withholding. In option A that is $30,000 against $39,180 of federal tax, so an estimated payment may be needed.
- Stacking a withdrawal on a deferred comp payout. Some deferred compensation plans pay in the year after separation. Adding a 401(k) withdrawal on top can push both into the 35% or 37% bracket.
- Choosing 72(t) payments when the Rule of 55 is available. A 72(t) series must continue for five years or until 59½, whichever is later. It is the right tool mainly for IRA money.
What to document for your children
A parent stepping back at 55 while the children are 7 and 10 is a decision they will notice but not understand. Write a one-page Decision Memo: why you left, which accounts funded the years to 59½, and what the numbers had to show before you said yes. As Kevin Luu puts it: “Your kids will inherit your money. Will they inherit your judgment?”
Frequently asked questions
Is the Rule of 55 worth it if I plan to keep working somewhere else?
It can be. Once you separate from the employer in or after the year you turn 55, you can take a new job and still withdraw from the old plan without the penalty. But new wages raise your bracket, so a withdrawal in a high-income year can cost far more in tax than the penalty you avoid. Using the Rule of 55 and still working covers the details.
Does the Rule of 55 apply to an old 401(k) from a previous employer?
No. It applies only to the plan of the employer you separate from in or after the year you turn 55. An older 401(k) stays under the normal rules until 59½, unless you roll it into your current employer’s plan before you leave and that plan accepts roll-ins. Our guide to the 401(k) age-55 rule walks through eligibility.
Is it better to use the Rule of 55 or let the 401(k) keep growing?
If another account can cover spending at lower tax, leaving the 401(k) invested keeps its tax deferral. The Rule of 55 is most useful in years when household income is low, before required minimum distributions begin, because withdrawals then fill lower brackets that would otherwise go unused.
Next step
If you expect to leave a senior role within two years, put your separation date, spouse income, deferred comp schedule and account balances on one calendar and test which account should fund each year. Our retirement and employee benefits and tax management work covers this, and a Tax & Wealth Assessment is the usual starting point.
