Qualified birth/adoption distribution
IRC 72(t)(2)(H) lets you take up to $5,000 per child from a 401(k) without the 10% early-distribution tax. The cap is not COLA-indexed.
QBAD = min(requested, $5,000 − already taken for this child)
Example: $5,000 requested, nothing taken → $5,000 QBAD and $500 of 10% tax avoided. Ordinary income still applies.
