I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
Yes, if you wait 2 month after reaching full retirement age, your social security benefit will increase for a couple of reasons.
1. First, your retirement benefit increased a full 2/3% for each month you delay retirement after full retirement age all the way to age 70.
2. By retiring in January, you will get the benefit of the next cost of living increase---which has been running about 1 to 2% per year.
So yes, there is always a benefit to waiting a few months after your full retirement age to claim your retirement benefit, and even greater benefit to waiting more than a few months.
