I celebrated my 63rd Birthday last month. I plan on semi-retiring this year to spend more time with the Family. I recently used the Benefits Calculator to acquire an estimate of what my monthly Social Security benefit would be each month. The calculator asked for an estimate of my 2016 earnings. I plugged in the estimated amount and my monthly benefit per the Calculator was exactly what I expected it to be.
My question is this. I'm self-employed and my earnings in 2016 were greater than my earnings in 2015. If I file for benefits this month without having filed last years taxes yet, how will that affect my monthly benefit if I apply now? I paid all four of my quarterly tax estimates, but haven't filed a return yet.
Since the Benefits Calculator required my last years estimated earnings, if I file now will my monthly benefit be lower since I haven't filed my 2016 taxes yet???
