Traditional IRAs (including Rollover IRAs), SEP IRAs, SARSEP IRAs, and SIMPLE IRAs are all eligible to be converted to a Roth IRA (SIMPLE IRA contributions cannot be converted to a Roth IRA during the first 2 years of starting your contributions). Rollover IRAs containing assets from an employer-sponsored plan account are also eligible to be converted. In addition, balances from employer-sponsored savings plans (e.g., a 401(k) or 403(b) plan) that are eligible for distribution and rollover may generally be converted (for example, when you are no longer working for the company sponsoring the plan). Consult your own tax advisor.
