Solo 401K plans are retirement plans that provide for discretionary employee and employer contributions. These Plans were created in 2001 by the Economic Growth and Tax Relief Reconciliation Act (EGTRRA). The act allowed for changes to the laws governing traditional 401K plans. The changes allowed small businesses to enjoy the advantages of 401K plans without the costs that accompany regular 401K plans. Some estimate that 19 million people may be able to take advantage of these plans.
