What is IRA Basis?
IRA basis is the sum of after tax contributions made to your Individual Retirement Account. This can include traditional IRAs, rollover IRAs, inherited IRAs, and Roth IRAs. Many taxpayers fail to keep track of after tax contributions to these retirement accounts. This is not a good idea because you end up paying tax twice on the money you contribute to your IRA; once on the way in and once on the way out.
