Frequently Asked Questions
How is UK National Insurance calculated?
0% is paid on earnings up to the Primary Threshold (£12,570/year), 8% on earnings between the Primary Threshold and the Upper Earnings Limit (£50,270/year), and 2% on earnings above that.
Do these thresholds change?
Yes, National Insurance thresholds and rates are set by the UK government and can change each tax year (usually announced in the Budget) -- treat these as editable defaults and verify against gov.uk for the current tax year.
