Generally, if you're an employee who earns more than the standard personal allowance £12,570 in the tax year 2023/24), you’ll receive tax relief on your contributions.
You’ll need to check with your scheme how this works for you and if you need to do anything to claim all the tax relief you’re entitled to.
If you earn less than the standard personal allowance and so don’t pay tax, then you won’t get receive tax relief if your employer operates a ‘net pay’ scheme.
If your workplace scheme operates under ‘relief at source’ – you’ll receive basic (20%) tax relief on your contributions. This is regardless of your level of pay.
If you’re affected by this, you can check with your employer what type of scheme they offer and if they would be willing to change to a relief at source scheme.
Be aware that your employer has to use the same method for all employees in the scheme.
