WARNING: Tracking Roth IRA conversions on your tax return is not easy. Many tax professionals struggle in this area. If you do not document after-tax IRA contributions and Roth conversions correctly on Form 8606 in your tax return, you will highly likely get a letter from the IRS saying you owe some taxes. Even though this situation can be rectified with proper documentation, it is never fun to get a letter from the IRS!
