Tax Deductor Configuration

Tax Deductor Configuration

We are setting up payroll for one of our clients. And we have a problem here.
In the Tax settings, we have to maintain 'Tax Deductor's Name', we are allowed to only put in the names of employees. 
We want to put in the name of the Owner, who is not an employee and also will not draw salary.
But there is no way to put the owner's name as Tax Deductor.
Or did we miss something?
