Your Dad's 401(k) Plan May Not Be as Flexible as an IRA
Moving a father's 401(k) to an inherited IRA avoids a $34,000 tax spike by spreading withdrawals over 10 years.
In brief
Moving a father's 401(k) to an inherited IRA avoids a $34,000 tax spike by spreading withdrawals over 10 years. Inheriting a 401(k) as a lump sum triggers higher taxes than spreading withdrawals over 10 years under IRS rules. Originally reported by 24/7 Wall St..
Inherited 401(k) Tax Problem
A 58-year-old single woman inherits her father's $400,000 401(k) plan after he dies at 70 in 2025.
Lump Sum Tax Spike
Taking the full balance as a lump sum triggers $123,664 in federal tax versus $8,964 per year for 10 years.
Section 402(c)(11) Transfer

Direct trustee-to-trustee transfer moves dad's 401(k) to inherited IRA without 20% withholding tax.
10-Year Clock Rules
Beneficiaries must empty inherited IRA by December 31, 2035 for a 2025 death, with annual withdrawals starting in year 10.
Tax Bracket Impact
In 2026, $40,000 annual withdrawals stay below 24% tax bracket while lump sum pushes into 35% bracket.
Avoiding 25% Penalty
Missing annual withdrawals triggers 25% excise tax on shortfall, reducible to 10% if corrected within window.
Optimal Withdrawal Strategy
Withdraw enough each year to stay below 24% tax bracket while avoiding Medicare premium spikes.
Tax Professional Advice
Run numbers with CPA or fiduciary advisor before plan sends lump sum check to avoid tax spikes.
