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Roth earnings have separate five-year rule from converted amounts that trigger 10% penalty if withdrawn before 59½.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

Withholding tax on Roth conversions under 59½ triggers 10% early withdrawal penalty if not rolled over within 60 days
