What is the key administrative difference between salary sacrifice and making an after-tax pension contribution?

Answer

Claiming tax relief on after-tax contributions requires declaration via Self Assessment, unlike salary sacrifice where tax is never paid upfront.

With after-tax contributions, the employee pays tax first and must claim relief back, necessitating a Self Assessment declaration. With salary sacrifice, the tax is never due on the sacrificed amount because gross pay is reduced beforehand.
