Edited to add: also, on $1,000 of payroll, the SS allotted amount that the employee pays is $76.50. The employer then pays their portion : $76.50 also. The SS rate is .0765% with OASDI & FICA for each the employee and the employer
Hence the (around) $150 figure I came up with Xena. For Roy, he would pay out his employee's and the company's social security ($76.50 + 76.50 = $153). So even though my calcs were rounded, they were correct.
As for 1099-ing my employees, I know it means hiring them as contractors, and I would make a decent attempt to work around it in the spirit of our government's making it difficult for anyone to start their own business...
