After a particularly prosperous year ( LSA, Unpleasant living, commital bonus, op allowance) my income was a lot higher than the payband and a bit extra I added on that I declared. Consequently my tax credits (4 kids - I do have a tv! just twins came along) has dropped substantially. This year I wont get any of these bonuses apart from a bit of LSA. Do I have any come back on this as obviously this year I will suffer only probably to be owed next year and it to go up. I tried to explain this over the phone and to appeal I need to write and was looking for any financial wizards to tell me that I am wasting my time, or any paperwork available through the Army I can quote or who I should see. Also if Op allowance is tax free should that be included??? I have never had any problems previously so have never given it much thought. Thanks in advance for any help you might be able to give.
