Older Veteran Asks about Special Social Security Credit for Military Service I served in the U S Army from January 1958 to Feb 1961. What increase should I receive for those years and who do I call and at what phone number? Signed: Proud Veteran Dear Proud Veteran: First, thank you for your military service! I expect you are referring to the “special extra credits for military service” which are available to some who served in in the US Military in earlier years. It is important to note that these “extra credits” take the form of an adjustment to your military pay record while serving and are not an incremental amount added to your monthly Social Security benefit because you served.Military pay has been subject to deductions for Social Security since 1957. Thus, while serving between 1958 and 1961 you paid SS tax on your military earnings. But, for purposes of determining your Social Security benefit, your military earnings record would be increased by $300 for each quarter you served on active duty, up to a maximum of $1,200 increase per year of service. That means for 1958 – 1960, when calculating your SS benefit, $1,200 would be added to your military earnings record for each year you served. FYI, for those who served after 1967, this adjustment was automatically made by Social Security. But for service years prior to 1967 (as in your case) you would need to inform Social Security of your service when you claimed SS and provide a copy of your military form DD-214 (your discharge papers). SS would then make the appropriate adjustment to your military earnings record prior to calculating your benefit amount. And, for clarity, additional credits for military service are not available to those who served after 2001.A key point to understand is that this adjustment to your military pay may – or may not – affect the amount of your Social Security benefit. Social Security determines your benefit amount based on your highest earning 35 years over your entire lifetime (adjusted for inflation). If, after you served in the military, you had at least 35 years of civilian employment where you earned more than your military pay, it is probable that your military pay is not included when calculating your Social Security benefit. If that is the case, it is likely that the “special extra credits for military service” would have ...
