I turn 70 in July 2017 and my wife turns 66 in May 2017. She will file and restrict her application for Spousal Benefits. Will her benefit be half of what I would have got at 66 if I filed or will it be based on the amount I get at 70.
Your wife's spousal benefit will be 50% of your PIA, or primary insurance amount, which is essentially your full retirement age rate. Your PIA includes any adjustments for higher earnings you may have had since age 66, as well as cost of living increases. However, your wife will not receive a percentage of any delayed retirement credits (DRC) you earn by waiting past full retirement age to start drawing your benefits.
