According to the above SSA link, from 1957-2001 a person was credited an additional $300 per quarter while on active duty with the US military. I served in the USMC from Feb. 1968 until Feb. 1972. When I printed off my lifetime SS earnings from the SSA website, it showed $1557 total yearly income for me in 1968. Which was about right as a Marine private didn't make much. However, if I'd have been credited the additional $1200 (4 yearly quarters X $300) that would have given me a yearly income of $357 and I'm sure I made more than that. Has anyone who had active duty looked into this. All I could get out of the agent at the local soc. sec. office is that I was given credit for my military time and it was in their computer. Not that I don't trust them, but I'd like to see something in black and white. This would not be a lot of money. Only an additional $4800 on my lifetime earnings, but if I have this coming I want proof that I'm getting it. Thanks to anyone for any time and help.
