Employee benefits and (especially in British English) benefits in kind (also called fringe benefits, perquisites, perqs or perks) are various non-wage compensations provided to employees in addition to their normal wages or salaries. In instances where an employee exchanges (cash) wages for some other form of benefit is generally referred to as a 'salary sacrifice' or 'salary exchange' arrangement. In most countries, most kinds of employee benefits are taxable to at least some degree.
