The Unified Grand Lodge of England, the umbrella body for masonic lodges in England and Wales, and the Chartered Accountants Benevolent Association will apply to give evidence to the charity tribunal review of the public benefit of benevolent funds.
Dominic Grieve, the Attorney-General, submitted a reference to the tribunal in January asking it to review whether a benevolent fund should have charitable status if it supported only those people linked to a certain individual, employer or unincorporated organisation.
Of almost 1,400 charities that could be affected by the tribunal review, 1,204 are masonic groups.
Nigel Brown, chief executive of the UGLE, said he felt the review was a positive step for his members.
"We feel that our public benefit isn't too restrictive," he said. "Masonic charities give to many different organisations. But this will be a useful process for us to understand what the situation is."
Nick Brooks, chair of Caba, said it also intended to take part in the review. "We're one of the largest benevolent funds, and chartered accountants often work with other benevolent organisations, so we felt it was appropriate for us," he added.
"We feel a number of benevolent funds haven't really realised everything that's going on. We're pleased to take a lead on this."
