If this was a solok then the Profit sharing part would be limited to the deductibility limit of 25% of $70,000, or $17,500. The total allocation to the owner/participant would be $35,500. If catch up eligible, add another $6,000.
The actual 415 limit is $53,000 for 2016. Take out $18,000 in deferrals and there is $35,000 left. Plus again $6,000 if catch up eligible.
