Yes! Many great charities, political organisations, and nonprofits in the United Kingdom are using Donorbox. Donorbox offers the ability for your UK donors to mark their donations as Gift Aid.
Once enabled, a Gift Aid section will be shown on the first page of your donation form.
Donors can then mark their donations for Gift Aid, so that you can reclaim the tax on them.
You can enable the Gift Aid option in your Donorbox localization settings.
In the UK, Stripe charges a low rate of 1.4% + 20p for European cards. See Stripe's pricing detail by clicking here.
Note: While Donorbox provides the donor with the option to mark their donation as Gift Aid, we do not claim Gift Aid in name of the organization. Check out this page for more details on claiming your Gift Aid.
