I am a student currently in TA, despite being my main income my TA tax code is BR ( Basic Rate ) and have justed volunteered for compulsory mobilisation on Telic 9. 1. How can my tax code for normal earnings be corrected - no-one in my unit seems to know and no-one can tell them? 2. Will I automatically get an appropriate tax code once mobilisation begins? Any help would be most - um - helpful.
