With view to the U.K.
Stamp duty should be retrospectively taken from all religious denominations. e.g. all Church of England properties are valued and Stamp Duty taken.
All "donations" should be taxed at gift rate of 40%.
The religious buildings will attract business rates of council tax as they are a business.
All religious properties will have to be maintained by the religion using its own funds. No government funding be it at national or local level.
All staff (vicars, priests, imams, money launderers) will be taxed the same as any other worker. Especially the perks like travel, cars, second homes etc.. all types of benefit in kind.
All profits will be taxed the same as any business. Profits being calculated like any other organisation.
Fuk the parasitic bastards.
