Do most of you just use the Paypal final numbers to figure out your yearly 'Net Income' total? Also, if you receive income (i.e. PP from iStock) from the last month of the year but it doesn't get received in your paypal account until the following year do you count it towards the previous year or current year?
I guess it depends where you live. I can count all my income from the tax year as the tax year ends on 5th April, but we have until the following Jan 31st to file our paperwork.
So indeed, I use the Paypal figures, though the currency conversion confuses things a bit, as I'm tempted to hold my earnings in US$ until the exchange rate is good, and I don't know how that would go down.
