You usually ‘receive’ a donation on the day you take ownership of it.
For example:
if you are given free leaflets, you receive the donation when the leaflets are handed over to you
if you are given a cheque, you receive the donation on the date that the cheque clears
if a donation is transferred directly into your bank account, you receive the donation on the date that it is received into your account
When do you accept a donation?
You accept a donation on the day you agree to keep the donation. For non-money donations, if you use the donation, you have thereby accepted it. If your party keeps a donation after the 30-day period, you are also deemed to have accepted it.
