Hi thanks for your Social Security question today. I think you are asking about "FAASF"
FAASF stands for File as a Spouse First.
It means that if you are married and you are coming up on eligibility to start receiving retirement benefits, you may find that it is better to file and get a benefit of 50% based on your spouse's benefit.
This allows your own benefit to increase. The longer you delay (but only up to Age 70) starting taking a benefit based on your own work record, the bigger your monthly benefit will grow. Once you start your benefit, it no longer can grow (other than Cost of Living)
This strategy only works if you had a significant work history yourself in addition to your spouse's work history.
In addition, your spouse must also have started taking his (or her) benefit first.
You can contact the SSA at 800-729-1213 to ask about your current benefit as a spouse as well as a projection of your own benefit both now and if you delay starting your retirement benefit.
Sorry, that phone number should read 800-772-1213
