I've been doing some research and believe except for eating out, I'm giving up my mystery shopping. I'm 64, on Social Security. I thought by doing mystery shopping, it might increase my Social Security a little in the future. Social Security only counts 35 years of your employment. I worked for 35 years. Since the government requires us to pay both sides of Social Security and Medicare (15.3%), it's no longer worth it to me. Many shops barely pay minimum wage, and figuring in time and gas, for me at least it's no longer worth it. In my area I make about $3000 a year, if I really push it. I'm sure if I lived in a city or other area it might be worth it. For now I'll just do shops with reimbursements. I had qualified for the Earned Income Tax Credit, that helped to off set the Social Security and Medicare tax. That ends for me this year. Being single, no children, you only qualify for the EIC tax credit if you're between the ages of 25 and 64. This year I turn 65. I'll find something else to do. I've enjoyed the work.
