Prior to EGTRRA, the maximum tax-deductible contribution to a 401(k) plan was 15% of eligible pay (reduced by the amount of salary deferrals). Without EGTRRA, an incorporated business person taking $100,000 in salary would have been limited in Y2004 to a maximum contribution of $15,000. EGTRRA raised the deductible limit to 25% of eligible pay without reduction for salary deferrals. Therefore, that same businessperson in Y2008 can make an "elective deferral" of $15,500 plus a profit sharing contribution of $25,000 (i.e. 25%), and—if this person is over age 50—make a catch-up contribution of $5,000 for a total of $45,500. For those eligible to make "catch-up" contribution, and with salary of $122,000 or higher, the maximum possible total contribution in 2008 would be $51,000. To take advantage of these higher contributions, many vendors now offer Solo 401(k) plans or Individual(k) plans, which can be administered as a Self-Directed 401(k), permitting investment in real estate, mortgage notes, tax liens, private companies, and virtually any other investment.
