First off, this isn’t legal advice. See your CPA/Attorney/Financial Adviser.
There are kind of two “Five year rules”,
The 5-year rule for IRA beneficiaries to withdraw 100% of the IRA by December 31 of the year containing the fifth anniversary of the owner’s death.
The 5-year rule for Roth Conversions
Bankrate explains the 5 year rule
Also AAII has an excellent review of ordering rules
Lastly the IRS Pub 590-B is the reference source
IF you take distributions early, you need to keep good records of the contributions.
You’ll need to order them into three groups.
Regular contributions.
Conversion and rollover contributions, on a first-in, first-out basis (generally, total conversions and rollovers from the earliest year first). See Aggregation (grouping and adding) rules, later. Take these conversion and rollover contributions into account as follows:
– Taxable portion (the amount required to be included in gross income because of the conversion or rollover) first, and then the
– Nontaxable portion.
Earnings on contributions.
Once the conversion occurs from Traditional to Roth, you need to wait 5 years to take a distribution without penalty, even if it’s an inherited Roth account.
The short of it is that you will want to distribute only up to contributions until five years pass from your conversion.
