Tax on a $50,000 401(k) withdrawal by other income
The 401(k) withdrawal stacks on top of whatever else you earn that year, so the same $50,000 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 | $3,820 (7.6%) | $1,780 (3.6%) |
| $25,000 | $6,780 (13.6%) | $4,640 (9.3%) |
| $50,000 | $9,350 (18.7%) | $5,860 (11.7%) |
| $100,000 | $11,564 (23.1%) | $7,700 (15.4%) |
| $150,000 | $12,000 (24.0%) | $11,000 (22.0%) |
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 | $3,820 | $5,000 | $8,820 |
| 60 | $3,820 | $0 | $3,820 |
| 66 | $2,854 | $0 | $2,854 |
| 73 | $2,854 | $0 | $2,854 |
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 |
|---|---|---|
| Arizona | $848 | 1.7% |
| California | $973 | 1.9% |
| Colorado | $612 | 1.2% |
| Maryland | $2,011 | 4.0% |
| Massachusetts | $2,280 | 4.6% |
| Michigan | $0 | 0.0% |
| North Carolina | $1,486 | 3.0% |
| Ohio | $732 | 1.5% |
| Pennsylvania | $0 | 0.0% |
| Virginia | $2,061 | 4.1% |
Spread over several years
Taking the same $50,000 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 | $3,820 | $9,350 |
| 2 years ($25,000 a year) | $1,780 | $7,700 |
| 4 years ($12,500 a year) | $0 | $6,000 |
Withholding, penalties and RMDs
A 401(k) plan must withhold 20% of a withdrawal paid to you, $10,000 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.

The calculator, set to this 401(k) withdrawal
Set to a single filer aged 60 with $50,000 of IRA or 401(k) withdrawals and nothing else. Add Social Security, a pension, your state or a spouse.
On $50,000 of income, the 2026 tax is about $3,820: $3,820 federal. $0 of your Social Security is taxable. The next $1,000 you withdraw from an IRA would cost $120 in tax.
