What Is the Separation From Service Rule, or Rule of 55?

Money taken out of a 401(k) before age 59 1/2 usually owes a 10% additional tax in addition to income tax. The separation from service exception, which most people call the Rule of 55, is one of the IRS exceptions to that extra charge. If you leave Raytheon during or after the calendar year you turn 55, withdrawals from Raytheon's qualified plan, such as its 401(k), are not subject to the 10% additional tax. Income tax still applies to pretax dollars. The IRS test turns on when you separate from service, not on why: the publication that explains it sets no condition about retiring, resigning or being laid off.

Why Does the Year You Leave Count, Not Your Age at Withdrawal?

The test looks at the year your job ends. Someone born in November who leaves Raytheon in March of the year they turn 55 can still qualify, even though they are 54 on their last day. It does not work in reverse. IRS Publication 575 gives the example of an employee who left a job at 49 and took a distribution in the year he turned 55; because he separated before that year, the exception did not apply. If you are weighing a departure at 54, a few months on the calendar can change the tax result.

Which Accounts Does the Rule of 55 Cover?

The exception applies to qualified employer plans, such as a 401(k) or a traditional pension plan, and the IRS marks it "no" for IRAs, SEPs and SIMPLE IRAs. It also follows the job you are leaving. A 401(k) from an employer you left at 48 does not qualify just because you later separate from Raytheon at 56, because the separation that counts is the one from the employer whose plan pays you. Some people roll older 401(k) balances into their current employer's plan while still working there, if the plan accepts roll-ins, so the money sits in the plan they will leave at 55 or later. Ask Raytheon's plan administrator and a tax professional how rolled-in money is treated before you count on that approach.

What Happens If You Roll Your Raytheon 401(k) Into an IRA?

Moving the money to an IRA ends the Rule of 55 for whatever you move. An IRA withdrawal before 59 1/2 generally owes the 10% additional tax unless an IRA exception applies. If you expect to need cash between 55 and 59 1/2, one approach is to leave enough in the Raytheon plan to cover those years and roll over only the rest. Whether that works depends on your plan's rules for partial withdrawals after you leave.

Does Raytheon's Plan Have to Offer Rule of 55 Withdrawals?

The tax exception comes from federal law, but the plan document decides how and when former employees can take money out. Some plans let you take withdrawals whenever you like; others allow a single lump sum, or limit how often you can request a partial payment. A plan that pays only a lump sum can push a large amount into one tax year, which may raise your bracket. The distribution section of the summary plan description spells out these rules, so read it before your last day.

How Are Rule of 55 Withdrawals Taxed?

Skipping the 10% additional tax is not the same as skipping income tax. A lump-sum or partial withdrawal paid to you, rather than sent directly to another plan or IRA, comes with mandatory 20% federal income tax withholding. That 20% is a prepayment, not the final bill; depending on your total income for the year, you could owe more at tax time or get some back. Taking withdrawals in a year when your paycheck has stopped, often the year after you leave, may keep more of each dollar in a lower bracket.

What About Police, Firefighters and Other Public Safety Workers?

Qualified public safety employees of a state or local government, in a governmental plan, can use the exception starting in the year they turn 50 instead of 55. SECURE 2.0 added a second path: 25 years of service under the plan, if that comes first. The same age-50-or-25-years rule applies to private-sector firefighters, and the IRS extends the same treatment to certain federal law enforcement officers, corrections officers, customs and border protection officers, federal firefighters and air traffic controllers. If you or your spouse works in one of these roles, check that plan's rules separately.

What If You Leave Raytheon Before the Year You Turn 55?

A series of substantially equal periodic payments, often called 72(t) payments, is the main alternative for taking money before 59 1/2 without the 10% additional tax. From a workplace plan, you must have separated from service before the payments start; from an IRA, you can start at any age. Payments are figured over your life expectancy using one of three IRS methods, and the two fixed methods let you use an interest rate up to the greater of 5% or 120% of the federal mid-term rate. The payments are hard to stop once they start. Payments must continue until the later of five years or age 59 1/2, with no extra withdrawals or deposits, so someone who starts at 52 is locked in until 59 1/2 and someone who starts at 57 is locked in until 62. Changing the series early brings back the 10% tax on that year's payments plus a recapture tax, with interest, for the 10% skipped in earlier years. A one-time switch from a fixed method to the RMD method is allowed without that penalty.

Which Other Exceptions Can Apply to a 401(k) Withdrawal?

Besides the Rule of 55 and 72(t) payments, the IRS lists other exceptions for workplace plans, including:

• Total and permanent disability, or death
• Unreimbursed medical expenses above 7.5% of adjusted gross income
• Up to $5,000 per child for a qualified birth or adoption
• One emergency personal expense distribution a year, up to $1,000
• Up to $22,000 after a federally declared disaster where you live
• A distribution to a domestic abuse victim, capped at half the account or $10,500 for 2026, whichever is less
• A terminal illness certified by a physician, an IRS levy, or a payment to a former spouse under a qualified domestic relations order

Several exceptions people expect to find apply only to IRAs, not 401(k)s: health insurance premiums paid while unemployed, higher education costs, and up to $10,000 for a first-time home purchase.

Should You Use the Rule of 55?

That depends on what else you have to live on. The rule removes one tax; it does nothing to make the money last longer. Each dollar withdrawn at 55 stops growing tax-deferred, and the rest of the balance may have to cover 30 years or more. If cash or a taxable brokerage account could carry you through the gap years, compare that with leaving the 401(k) untouched for now. If the 401(k) is most of what you have, the rule may let you bridge to Social Security or a pension without the 10% charge. Plan for health coverage at the same time, because COBRA generally runs up to 18 months and Medicare does not begin until 65. Your employer's own plan rules decide how much of this is possible.

What Can You Take From Raytheon's 401(k) When You Separate?

Raytheon's own plan document spells out exactly which payout choices open up once you leave. At termination, the RTX Savings Plan generally pays benefits as a lump sum, though a participant leaving due to retirement may instead elect installments paid over two to twenty years. A participant's own contributions stay fully vested at all times, while Raytheon's matching and retirement contributions generally vest after two years of continuous service. Participants may also borrow up to the lesser of 50% of their vested balance or $50,000, repaid over one to five years at the prime rate plus 1%. Check with Raytheon's plan administrator which payout option and any outstanding loan terms apply before you separate.
