I'm just doing my income/expenses for last tax year (2012/13) so that I can inform Tax Credits and ultimately hand over to DH to do my tax return.
My question is, if I wrote the invoice on April 26th 2013 for work done in March 2013, and it was paid sometime in May 2013, which tax year's income does it come under? Is it 2012/13 because that's when it was earned, or 2013/14 because that's when it was invoiced/received?
