Failing to complete an indirect 401(k) rollover within 60 days triggers income tax and a 10% penalty on the entire balance.
Account holders face immediate taxation and a 10% early-withdrawal penalty if they miss the IRS 60-day deadline for indirect 401(k) rollovers. The rule applies to distributions received as checks made out to the participant, not direct trustee-to-trustee transfers.
Indirect rollovers also require 20% federal tax withholding upfront, which must be covered from personal funds to avoid partial taxation. The IRS treats missed deadlines as early withdrawals, subjecting the full balance to ordinary income tax and penalties for those under 59½.
Direct rollovers avoid the 60-day window and withholding, preserving the full balance in tax-deferred status. The IRS enforces the rule procedurally, with no exceptions for unintentional delays.
