Is there any way to check if charities have actually claimed back tax relief on my donations. I don’t see anything on my tax returns or never got notified.
In my experience neither the charity nor Revenue notify donors when the charity has claimed tax relief on a donation.
As far as I know, the only way to know if they claimed relief on your donation is to ask them (the charity).
I've done it many times (donation > €250 and CHY1 form returned) with several different charitable bodies and never once received any notification about if/when/whether or not the charity claimed tax relief on the donation.
