I am a sole proprietorship with a solo 401K., no employees. When I ask TurboTax to calculate the max solo 401K contribution, it gives me a total of $36,000. It then says that only $24,000 is deductible. Not sure which amount to use now, the max contribution number or the max deductible number. Obviously, the higher contribution results in lower overall tax, but I just want to make sure I'm doing this correctly and not missing anything important. Thanks.
