Gift Aid & The Higher Rate Taxpayer

Prior to the start of the Institute of Fundraising campaign, how many of us really bothered about the higher rate taxpayer and Gift Aid?

Can anyone point to some examples where their charity work has had some success?

Do we partner with accountants, send out self assessment forms at the tax return dates, or even identify who amongst our donors are higher rate taxpayers?

I have never been asked to identify myself as a higher rate taxpayer when donating to a charity in the past. Has anyone else?

Thoughts appreciated.
