I am from the UK and am a fulltime IM'er. Like the majority here i get paid mostly in US Dollars. How do i do the currency conversion in my tax return? If i got paid for example $2,500 in March via paypal, do i find the exchange rate on THAT particular day, or do i total up the dollar amount for that month and then work out the UK Pound amount for that month, or do i just do it all in one big go at the end? I'm really confused about this, thanks to anyone who can help me out.
