FAQ
What is the 10% early withdrawal penalty?
Under IRS Code §72(t), taking money out of a 401(k) before age 59½ normally triggers a 10% additional tax on top of ordinary income tax. A $10,000 withdrawal can cost about $1,000 in penalty alone, plus federal and state income tax.
How is the net amount I receive calculated?
Start with the gross withdrawal, then subtract federal income tax, state income tax (if your state has one), and the 10% penalty when no exemption applies. What is left is your take-home amount.
Does the penalty apply at age 59½?
No. Once you reach 59½ the 10% early-distribution penalty no longer applies. You still owe ordinary income tax on the withdrawal, but the extra penalty is gone.
What exemptions avoid the 10% penalty?
Common ones include the Rule of 55 (separation from service at 55+), 72(t) substantially equal periodic payments (SEPP), total disability, QDRO divorce orders, and certain unreimbursed medical costs. Each has its own rules.
