The cap on income tax reliefs that George Osborne announced in the Budget will negatively affect many charitable organisations, both large and small.
It will discourage the major donors that give large, one-off donations to many charities. And it's important to remember that today's gifts are also tomorrow's grants. These donors are behind many of the grant-giving trusts and foundations that support frontline organisations.
National Council for Voluntary Organisations (NCVO) believe the Chancellor must reverse this decision. They have recently launched a campaign called Give it back, George - drop the charity tax.
The NCVO are encouraging charitable organisations to help with this campaign.
