I’ve written about Solo-Ks before over at my other blog home, Slate’s BizBox. (See The Wonderful Solo-K). It’s a special retirement plan for the self-employed or small business owner with no employees (other than their spouse) to establish 401(k) plans and to max out their deductible retirement plan.
But as we creep toward 5500 filing time for 2008 calendar plans (July 31, 2009 unless extended to October 15, 2009), there is a yellow caution light out. And that’s whether Form 5500 has to be filed for these so-called "owner-only" plans.
