Congratulations on retirement. You'll find you'll probably stay busy doing the things you never had time for before you retired.
If he just turned 64, he'll not reach his full benefit until about 67-1/2 or so. Since he's got his pension and is doing side jobs, he'd be limited in how much he can make until he reaches his full benefit year, without losing a little on his SS. If I were him, I'd let the SS go until his full benefit year, then his SS payments will be about 6% greater than if he started now, and if he continued to work side jobs, there would be no restriction on how much he could make. I retired at 65, my full benefit year was 66, so I only lost 3% of my full benefit amount, which was easily filled and then some by my pension. I started working with a friend who does landscaping and maxed out how much I could earn in 9 months, and had to give up a few bucks of my SS for the last three months before I turned 66. I'm almost 69 now, still doing landscaping 3 days a week (6 hrs./day), and making more money now with my SS and pension than I did working full time in health care. And I'm being paid a third as much landscaping as I did as an RN. I do the work because I love working outside and not for the money.
