Larry, My husband (63) will be applying for social security in October, 2017. I turn 66 (my FRA) in late January, 2018. I will be applying for restricted spousal benefits and let my social security grow until I am 70. Do I have to wait to fill out the application until my actual birthday 1/28/52 or can I apply a few months early so the benefits start soon after my birthday? No where have I read when you can complete the online application for restricted benefits, but I know I cannot receive benefits until my 66th birthday. Thank you.
