These calculations are done using a script running in your Web browser on your own device—your data is not sent over the Internet. These calculations are based on the IRS Table 2000CM Mortality Table. However, these calculations may not match the actuarial tables in IRS Publications 1457, 1458, and 1459, so you should consult the actuarial tables in those IRS Publications for purposes of tax return preparation or any other important project. These calculations should not be relied upon as tax or legal advice on any specific facts or circumstances. These calculations are intended as estimates for general educational and informational purposes only, and you should consult with a CPA or attorney licensed to practice in your state concerning your own situation and any specific tax or legal issues you may have.
