A Qualified Retirement Plan is a plan that is regulated by the ERISA tax code. This includes 401Ks, Pensions, IRAs/Roth IRAs, SEPs, SIMPLE, Cash Balance Plans, Profit Sharing Plans, and some ESOPs.
When an account is "Qualified", with the exception of ROTHs, it means it was contributed to or "funded" on a pre-tax basis.
