Solo 401k Contribution Limits

In 2009 the total contribution limit for a Solo 401k is $49,000 or $54,500 if age 50 or older (2008 limits are $46,000 or $51,000 if age 50+). The annual Solo 401k contribution consists of 2 parts a salary deferral contribution and a profit sharing contribution. The total allowable contribution adds these 2 parts together to get to the maximum Solo 401k contribution limit.

Solo 401k contributions are flexible. Both the salary deferral and the profit sharing contributions are discretionary and can be changed at anytime based on business profitability.

The contribution limits can be doubled for husband and wife businesses. Businesses with a spouse on the payroll can also contribute to the Solo 401k. There would be one Solo 401k for the business with two participants.

Provided a business owner and spouse have sufficient income from the business, both may be able to contribute $49,000 each or $54,500 each if both are age 50+ in 2009.
