How much can I earn before paying National Insurance as a freelancer?

you've got a personal allowance threshold of around £12,570 for income tax, but national insurance works seperately and has its own limit. for class 2 national insurance as a self-employed person, you only pay if your profits are above £6,725 a year (as of 2026). below that figure and you're exempt, though you can still choose to pay voluntarily if you want to protect your state pension entitlement.

class 4 national insurance kicks in when your profits go over around £11,908, and then you pay a percentage on earnings above that threshold. so in theory you could earn up to £11,908 without hitting class 4 contributions, but class 2 still applies once you cross £6,725. most freelancers end up paying both once they're making decent money.

the key thing is keeping proper records of your actual profit after expenses - that's what matters for these thresholds, not your gross income. if your turnover is high but your profit is low because of business costs, you might stay below the limits. also check if you're registering for vat, because that has seperate thresholds and complicates things further. worth getting an accountant or using decent bookkeeping software to track this properly.
