Salary Sacrifice Checks Before You Sign
Pensionable pay
Check whether the arrangement reduces pensionable pay. A tax saving can be poor value if it reduces NHS pension accrual unexpectedly.
Annual allowance
Salary sacrifice can reduce threshold income but may not reduce adjusted income in the way people expect. Model tapering before relying on it.
Statutory pay and lending
Lower contractual pay can affect maternity pay calculations, sick pay, mortgage affordability, and some benefit assessments.
Exit terms
Car, bike, and technology schemes often have early-exit costs if you change employer, retire, go on leave, or reduce hours.
