Tax on a $250,000 401(k) withdrawal by other income
The 401(k) withdrawal stacks on top of whatever else you earn that year, so the same $250,000 costs more when other income has already used the low brackets. Other income here is pension or wage-like ordinary income; age 60, no state tax.
| Other income | Single | Married filing jointly |
|---|---|---|
| $0 | $51,304 (20.5%) | $37,468 (15.0%) |
| $25,000 | $58,494 (23.4%) | $43,468 (17.4%) |
| $50,000 | $64,314 (25.7%) | $47,688 (19.1%) |
| $100,000 | $72,464 (29.0%) | $53,828 (21.5%) |
| $150,000 | $78,400 (31.4%) | $58,128 (23.3%) |
By age
Before 59½ a 401(k) or IRA withdrawal also owes the 10% additional tax unless an exception applies. From 65 the standard deduction is larger and the senior deduction (2025 to 2028) lowers the tax.
| Age | Federal income tax | 10% additional tax | Total |
|---|---|---|---|
| 50 | $51,304 | $25,000 | $76,304 |
| 60 | $51,304 | $0 | $51,304 |
| 66 | $50,648 | $0 | $50,648 |
| 73 | $50,648 | $0 | $50,648 |
By state
State tax on the same 401(k) withdrawal, single, 60, no other income. The nine states with no income tax take nothing.
| State | State tax | Share of the 401(k) withdrawal |
|---|---|---|

| California | $18,861 | 7.5% |
| Colorado | $9,412 | 3.8% |
| Maryland | $12,400 | 5.0% |
| Massachusetts | $12,280 | 4.9% |
| Michigan | $7,501 | 3.0% |
| North Carolina | $9,466 | 3.8% |
| Ohio | $6,438 | 2.6% |
| Pennsylvania | $0 | 0.0% |
| Virginia | $13,561 | 5.4% |
Spread over several years
Taking the same $250,000 in equal parts over more years keeps more of it in lower brackets. Total federal tax, single, 60:
| Taken over | No other income | $50,000 of other income a year |
|---|---|---|
| One year | $51,304 | $64,314 |
| 2 years ($125,000 a year) | $37,468 | $53,828 |
| 4 years ($62,500 a year) | $21,280 | $48,400 |
Withholding, penalties and RMDs
A 401(k) plan must withhold 20% of a withdrawal paid to you, $50,000 here; an IRA withholds 10% unless you choose otherwise. Withholding is a prepayment and is settled on your return. Leaving your employer in or after the year you turn 55 lets that plan pay out without the 10% penalty (the Rule of 55); before then, 72(t) payments are the other way in.
From 73 or 75, required minimum distributions force withdrawals each year whether you need them or not; the RMD tables by age and balance show how large they get.
