This is a followup to a question I asked back in June. My Roth IRA contains regular contributions as well as conversions from both deductible and non-deductible IRA contributions. I have not tracked the basis over the years, but I believe I have all the requisite paperwork (specifically forms 5498 and 8606). Is there a simple procedure/algorithm for computing my basis today? It seems relatively straightforward, but I just want to make sure I'm avoiding all the pitfalls.
Thanks, Bill
