A company may only identify itself as a charity if it is on the Charities Register. A charitable trust, which is a fund or piece of property used for charitable purposes and is overseen by a board of trustees, is one of the legal rights that a Registered charity may enjoy.
Charities typically do not have to pay income tax, corporate tax, capital gains tax, or stamp duty (on certain forms of income). Additionally, charitable donations are frequently exempt from inheritance tax.
The general public believes that registered charities are more reliable than unregistered ones. This might increase support from the general public for your group, attract new volunteers, and help with fundraising.
