I recommend 31 March for simplicity. Basically will mean your earnings will coincide with the tax return year making life simpler. In old days was beneficial to choose 30 April - basically gave you an 11 month cash flow benefit between when you made your money and when you had to pay tax on it. I think now does not really matter. Might also depend on whether you expect income to be reasonably constant or to increase. If the latter 30 April may still be best.
