Hi Becky
We are unable to comment on specific scenarios.
Adjusted net income is your total taxable income before any Personal Allowances and less certain tax reliefs.
‘Tax relief’ means that you either:
- Pay less tax to take account of money you’ve spent on specific things, like business expenses if you’re self-employed. Or,
- Get tax back or get it repaid in another way, like into a personal pension
If your employer deducts contributions from your gross pay before tax is calculated then you would not deduct again for the adjusted net income as the tax relief would already have been applied and your salary reduced.
If you make contributions eligible for tax relief from your net wage (after tax), for example payments made gross to pension schemes, then these would reduce your adjusted net income.
You can find more details, and work out your adjusted net income here:
Personal Allowances: adjusted net income
Thank you.
