I've been meaning to sign up for a few groups for a while and was nudged to action by the If you had to choose a feminist org to join...? thread.
But while I was signing up I was struck by the giftaid statement they encourage you to sign up for. Since I currently stay at home looking after kids while my husband brings in the cash, I'm not technically paying tax under my own steam. So when I sign up for something, paying with the (taxed) money my husband has brought into our household I don't seem to be able to giftaid. While my husband, using the same money, would be able. This would seem to put non-working partners (i.e. generally women) at a disadvantage.
Is there a loophole that allows me to be as valuable (money wise) to a charity as my husband is? Or is this structural discrimination?
