You’d be much better off contacting Social Security to get your answers.
Not to blow you off, but they are the experts.
I did and got 3 different answers to the same question. It’s why I posted it here.
Since you will continue to work do not take SS.
Here’s a rough number to use. For every month you work past hour SS retirement date your benefit will increase by . 75 %. So if your Benicia is 1000, then working and contributing to SS, your benefit goes to $1007.50. 2 months to $ $1015.00 etc. one year $1,080. I say contribute and work. Ask what the minimum you have to work and contribute to get that .75 % .
I had a question and went to the local social security office. They told me I needed to go to the IRS office. I went to the IRS office, and the lady there told me I needed to contact social security. I finally got a live person on the phone at the national social security office. She did not know the answer to my question and said nobody in her office knew the answer to my question. She said, “If I were you, I’d Google it.”
