April 30, 2007 – The IRS published Final Regulations on Limitations on Benefits and Contributions Under Qualified Plans, T.D. 9319, also known as the Final 415 Regs. The last time the IRS released comprehensive regulations pursuant to Code section 415 was on Jan. 7, 1981. These regulations update those 1981 comprehensive regulations and incorporate guidance the IRS issued in the form of notices and revenue rulings between Jan. 7, 1981 and April 30, 2007 along with statutory changes made by Congress during this time frame.
Some of the changes made by Congress during this time frame include:
