Hi, I want to know what you all do for record keeping to keep track of basis for your mega backdoor and backdoor Roth’s. I have 8606 forms (several amended due to mistakes), 1099 forms, and 1040 forms. Is that all I need? I’ve been doing this since 2012 and IRS says to keep 3 years worth of forms, but do I need to keep forms longer? Any of you in withdrawal phase? What does IRS want when you withdraw?
Thanks!
