Question: I am 80 years old and own an IRA. Can I assume that I will continue under the SECURE Act to use the existing IRS lifetime tables for calculating required minimum distributions for 2020 and beyond?

Answer: Yes -- if someone is age 80 today and already taking required minimum distributions, or RMDs, from an IRA, nothing in the SECURE Act would change that, says Jamie Hopkins, director of retirement research at Carson Group and author of Rewirement: Rewiring the Way You Think about Retirement!

However, he notes, the IRS has proposed changes to the life tables that came out in November and are expected to be finalized next year and likely active in 2021, which would likely lower RMDs for many.
