SOT means Special Occupational Taxpayers and TTJ means Tax Tribunal Judgement. Unfortunately there isn't an exact information regarding the CTR and ITD items. From what it seems CTR means either Company Tax Rate or Current Tax Referencer while ITD comes from Income Tax Department or Income Tax Tribunal Decisions. I suggest you contact the Income Tax Case Laws Digest developers for further information. You can get in touch with them using
