Ah well, then more problems come into play. If your income exceeds 100K then you loose your personal allowance at the rate of a pound of ever two quid you go over 100K. It does not surprise me that in your position HMRC will not budge with such a large income, a big chunk of which will be at the higher tax rate of 40%, and any adjustment will have to wait until you self assess at the end of the 15/16 tax year. There is always the possibility that you will actually own tax at the year end when the chips are down. If that is the case you will have until 31 January 2017 to pay any additional tax assessed.
I am so sorry to have to rain on your parade.
