The government used to send you “your Social Security Statement” every year. No more. Now they might send one every three years, if you haven’t established an online profile with them https://secure.ssa.gov/RIL/SiView.do. Once you set that up they stop sending reports altogether. My last report is from 2010.
Every year I log on to check to see that my earnings record has been correctly updated and to see what my new benefit estimates are. Trouble is, I can’t compare year to year like I used to with the paper statements. The website shows you current info, not past info.
You can, however, print and/or save your current statement. That way you can maintain a history. I’m missing our 2011-2014 statements because I didn’t think to do this. But, from now on I won’t forget. I’ll be able to see how our earnings affect our benefits from year to year.
