When Can You Withdraw From Your 401(k)? Taxes, Penalties, and Rules ER Docs Need to Know
When Can You Withdraw From Your 401(k)?
This is really a three-part question:
When can you withdraw?
What tax will you owe?
What penalty will you owe?
Let's work through each one.
Part 1: When Can You Withdraw?
First, a quick note on terminology. You may have one of several retirement accounts through your employer:
401(k): Offered by for-profit employers — a private EM group, or your own entity if you do locum work.
403(b): Offered by nonprofit employers, like an academic or nonprofit hospital.
A 401(k) and 403(b) behave the same way when it comes to withdrawal rules. We'll use "401(k)" throughout this post.
You can withdraw from your 401(k) when the terms of your plan allow it. The two most relevant triggers are separation from service and reaching age 59½. Many plans also allow hardship withdrawals — check your plan documents if that's relevant to your situation.
Note: Some employer plans include a 457(b) account, which has its own withdrawal rules. We'll cover that in a future post.
Separation from Service
You can withdraw from your 401(k) after you leave an employer, regardless of your age. Your options:
Roll it over (tax-free and penalty-free) into another 401(k) or IRA, or
Take a distribution payable directly to you.
The rest of this post focuses on direct distributions — money going into your pocket.
In most cases, you cannot withdraw from a 401(k) while you're still employed there and under age 59½. Check your specific plan to confirm.
After Age 59½
Once you reach age 59½, most plans allow you to withdraw even if you're still working for that employer. Again, check your plan to be sure.
Part 2: What Tax Will You Owe?
Pre-Tax 401(k)
Withdrawals from a pre-tax 401(k) are taxed as ordinary income. How much you'll owe depends on your situation:
A full-time practicing ER doc will likely pay 24%–37% federal income tax, plus state
A retired ER doc with thoughtful planning could pay as little as 12% federal income tax — a meaningful difference.
This gap is exactly why Roth conversions and distribution sequencing matter so much in retirement planning.
Roth 401(k)
Withdrawals from a Roth 401(k) can be tax-free, but the rules depend on what you're withdrawing.
Withdrawal of Contributions
Your Roth 401(k) contributions can always be withdrawn tax-free. The catch: each withdrawal is treated as proportionally part contributions and part earnings — you can't cherry-pick.
Example: You've contributed $50,000 to your Roth 401(k), which has grown to $100,000. If you withdraw $50,000, the IRS treats it as $25,000 in contributions (tax-free) and $25,000 in earnings (taxable unless the distribution is "qualified").
Qualified Distributions
A Roth 401(k) distribution is qualified — and therefore entirely tax-free — when you meet both of these conditions:
You've held this particular Roth 401(k) for at least five years. A Roth 401(k) from a different employer does not count toward this clock.
The distribution is made:
On or after age 59½, or
Due to disability, or
Due to death.
Continuing the example: your Roth 401(k) now holds $50,000 ($25,000 contributions + $25,000 earnings). If you're over 59½ and have held this account for at least five years, your entire $50,000 withdrawal is qualified and tax-free.
Part 3: What Penalty Will You Owe?
The Age 55 Rule (Rule of 55)
Most people assume you can't touch a 401(k) before 59½ without a penalty. But there's an important exception: the Rule of 55.
If you separate from service with an employer during the calendar year you turn 55 or later, you can withdraw from that employer's 401(k) without the 10% early withdrawal penalty.
Here's how it plays out in practice:
✅ No penalty: Leave EM Group A at age 55, withdraw from EM Group A's 401(k)
❌ Penalty applies: Leave EM Group A at age 52, withdraw from EM Group A's 401(k)
❌ Penalty applies: Leave EM Group A at age 55, withdraw from EM Group B's old 401(k)
❌ Penalty applies: Leave EM Group A at age 55, withdraw from an IRA
Pro tip: If you're planning to leave your current employer in the year you turn 55 or later, you may be able to consolidate your other retirement accounts first. Roll your old 401(k)s into your current 401(k) before you separate, then withdraw from the current plan. A few important caveats:
Your current 401(k) must accept incoming rollovers — many do, but not all.
Pre-tax IRA and old 401(k) funds can generally be rolled into your current plan.
Only Roth 401(k) funds can be rolled into a Roth 401(k). Roth IRA funds cannot be rolled in.
Before Age 59½ (General Rule)
Unless you qualify under the Rule of 55 above, withdrawals before age 59½ are subject to a 10% federal early withdrawal penalty. Some states add their own penalty on top.
There are exceptions — a full list is available on the IRS website. The most relevant ones for ER docs:
Disability
Death
First-time home purchase (up to $10,000 lifetime limit)
After Age 59½
No 10% penalty on any 401(k) withdrawals after age 59½.
One nuance for Roth 401(k) holders: if you haven't yet satisfied the five-year holding requirement, earnings withdrawn after 59½ are still subject to income tax — but not the 10% penalty.
