I received a lock In Letter last week from the IRS. Do I need to report it to security by chance?
For more background, I currently have a TS clearance and wanting to know if I need to report and do an SF-86c form to report me receiving this. Let me know …
Reach out to your CSO. They will tell you exactly what to do.
I never heard of this so I consulted my accountant… Google and Google CPA. Apparently this is a directive to adjust your tax withholding.
I can’t tell if this is really an adverse action (based on my extensive research 
) but it can’t hurt to report it. I don’t think this is an SF-86c though. I echo @clearedrob on this one.
