In 2018, the 401(k) plan celebrated its 40th birthday! Though extremely popular today, 401(k) plans came about almost by accident. IRC Section 401(k) was passed into law as part of the Revenue Act of 1978 and was included to limit executive compensation. However, in 1980, Ted Benna of the Johnson Companies used the provision to create and get IRS approval of the first 401(k) plan for his company. For this he is often referred to as the father of the 401(k).
After many rounds of negotiations, Congress passed the Tax Cuts and Jobs Act on December 20th, 2017. Though retirement plan limit reductions were included in many iterations of the bill, the ultimate effect on qualified plans was relatively minimal. There are two items of note that were included in the new law affecting loan repayments and IRA conversions.
