I made several Gift-Aided donations to charity on April 4th and received automated email receipts for each. However, April 4th was a Saturday and as I made the payments online, by debit card, they didn't actually get processed until Monday April 6th. I then received several receipts by letter, dated around April 7th.
For the purposes of a tax return and child tax credit forms, do these payments count in the tax year 2014‑15 as that is when they were made, or in the current tax year because that is when the bank processed them?
