As an organisation you can choose whether you would like GiveNow to issue receipts to donors on your behalf, for each active cause.
If you would like to issue your own receipts simply untick the 'Donation Receipt' box which is found in the 'Donation Details' tab when editing a cause (see how to list a new cause for help).
A sample receipt is below, for an example organisation that has DGR status.
If your organisation does not have DGR status, the information about tax deductibility and references to tax do not appear on receipts.
