Roth Conversion Trap

Roth Conversion Trap

A 58-year-old converted $80,000 from traditional IRA to Roth, checking 20% tax withholding box. The Roth received $64,000 while $16,000 went to IRS as unrolled distribution.

“She never saw the money. She never spent it. She never chose to take a withdrawal.”

Why $16,000 Triggers Penalty

The IRS treats withheld amounts as early withdrawals for savers under 59½, adding 10% penalty on top of regular income tax.

The 60-Day Fix

Roll over the $16,000 within 60 days by depositing outside funds into Roth to avoid penalty and income inclusion.

Tax Withholding Trap

State income tax withholding on IRA distributions creates same problem as federal tax withholding during Roth conversions.

Correct Conversion Method

Convert full amount with zero withholding and pay tax from outside account to avoid penalty and maximize Roth growth.

5-Year Rules Clarified

Roth earnings have separate five-year rule from converted amounts that trigger 10% penalty if withdrawn before 59½.

Critical Mistake

The form didn't warn about the penalty, causing the most expensive routine mistake in Roth conversions.

IRS Exception Rules

Exceptions like disability, medical expenses, or home purchases may avoid the 10% penalty for withheld amounts.

60-Day Rescue

Self-certification allows late rollover within 60 days for custodian errors or misunderstanding of withholding.
