Procorre - letters advising allocation of profits

[peasant2023]

I have just received a similar letter - I worked through procorre for 15 weeks in 2014 and now have a tax demand for twice what I earned in that time!! I dont understand how they calculate 1 - the loan amount, 2, the additional revised 'pay from all employments' in 18/19 figure. I would have thought that would be the same as the loan amount but it is 25% more? totally confusing & after speaking to the guy at the end of the phone at HMRC, im still none the wiser. Does anyone have a clue how this works?

They added the Loan to your 2018/19 income and taxed that at PAYE rates.
The figures are guesstimates and designed to cause panic so you'll take action.

You need to appeal within 30 days - Speak to a professional tax advisor

You will ultimately need to be able to prove how much you actually received in those 15 weeks to demonstrate your correct liability.
