Salary Deferral Contribution
Although the term salary deferral is used, these businesses do not provide a W-2 salary to the business owner. For businesses of this type, the salary deferral contribution is based on net adjusted business profit. Net adjusted business profit is calculated by taking gross self employment income and then subtracting business expenses and then subtracting 50% of the self employment tax.

You will want to ask your tax professional for assistance with this calculation.
