How do I get Army Reserve time credited for TIS and reflected on an ORB/IPERMS?

There is a conversion. They will adjust your new adjusted BASD off of this. I was active duty before I went to the guard. I got out a second time and then commissioned in the Guard before I transitioned back to the Regular Army. The simple math is that they will count how many retirement points you have the day you came back to active duty. They will then back date the time you have accrued as your new BASD. My PEBD is June 19, 2000 and my new adjusted BASD is March 13, 2007. Even if you are in the reserves you can acquire the same amount of points in a year that would equate to a month of active duty. So when you come back to the active side you will be credited with your reserve time and only have 19 years and 11 months. Usually with OCS and the other stuff you might get a few months. It is complicated to say the least. It take finance 3 weeks to figure mine out.

CPT (Join to see) that is not correct. The simple math is that 1 day of AD service in a reserve component is equal to 1 day of credit to your BASD. Retirement points aren't used in that way for BASD. We do use the Retirement points worksheet to determine the amount of active duty time served under the AD points section. But there is no conversion for reserve time to active duty time.

I am the person who calculates the time and prepares the DA 1506 for reserve Soldiers, prior service, and officers who need their BASD/PEBD adjusted. By regulation, S1 is required to do it, but Career Counselors spend two months learning about creditable service and work with it every day, so it usually falls on us to do it.
