For a standard UK PAYE employee, what is the general administrative burden regarding declaring the salary sacrifice itself?

Answer

The burden is generally minimal or non-existent, as the employer covers reporting.

For most employees in common UK workplace schemes, the administrative burden is kept low because the mechanism alters gross pay before standard Pay As You Earn (PAYE) calculations, and the employer reports the reduction automatically.
