Deductions are amounts taken from an employee’s pay, such as tax, National Insurance or pension contributions.
What are deductions?
Deductions are amounts subtracted from an employee’s gross pay before they receive their net pay. Some deductions are mandatory, such as PAYE tax or National Insurance. Others may be voluntary, such as pension contributions, charity donations or salary‑sacrifice benefits.
Payroll teams must ensure deductions are accurate, lawful and correctly reported. Incorrect deductions can affect employee trust and lead to compliance issues.
