Q. If I retire today, Social Security is S1,800 per month ($1,000 from the U.S. Postal Service and monies from my thrift savings account). Will this money from USPS and TSP affect my Social Security amount of $1,800? If so, how much?
A. The Social Security offset is based on earned income. Neither pension benefits, nor TSP distributions, are counted as earned income for this purpose.
