Your financial advisor doesn't independently know your basis in nondeductible traditional IRA contributions, Roth contributions and Roth conversion because these are determined only when you prepare your tax return. If your financial advisor provides you with any of this information, the financial advisor is only giving back to you information that you previously provided to him or her, which may or may not be current. Your financial advisor can only independently know about any traditional and Roth transactions performed through this advisor, not the tax consequences.
