Share Fisherman Tax & National Insurance UK 2026/27: The Special Class 2 Rules
Share fishermen — paid a share of the catch rather than a wage — are self-employed under a distinct HMRC category with its own National Insurance rate. Full guide to how catch shares are taxed and the special Class 2 treatment for 2026/27.
Why share fishermen have their own tax category
Fishing has one of the most distinctive pay structures of any UK trade: rather than a fixed wage, crew are typically paid a share of the catch's value (after deducting agreed costs like fuel, ice, and sometimes vessel running costs, according to the specific crew-share agreement used by that vessel/skipper). Because this income depends entirely on the catch, weather, quota restrictions and market prices, HMRC has long maintained a specific self-employment category for share fishermen, primarily to address one particular problem: standard self-employed workers have never had access to contribution-based Jobseeker's Allowance, but fishing's inherent unpredictability (bad weather stopping trips for weeks, vessel breakdowns, quota exhaustion) creates genuine income gaps that this benefit exists to soften — provided the fisherman has paid the right National Insurance to qualify.

When Class 2 National Insurance was abolished as a compulsory charge for most self-employed people from April 2024 (replaced functionally by Class 4 NI as the main self-employed NI contribution), share fishermen were specifically retained as an exception, continuing to pay their own distinct, historically higher, share fisherman Class 2 rate on a weekly basis. This isn't a disadvantage in practice — it's the mechanism that keeps share fishermen eligible for contribution-based Jobseeker's Allowance, a benefit most other self-employed workers cannot claim at all, providing a genuine safety net during periods when fishing simply isn't possible.
Worked example: share fisherman's trading profit
Scenario: a share fisherman's agreed share of the catch value across a tax year, after boat running costs are deducted per the crew agreement, totals £34,000.
Gross share income: £34,000
Deductible expenses:
- Oilskins, boots, protective equipment: £450
- Safety at sea and first aid certification renewal: £200
- Personal kit specific to fishing (knives, gloves, thermal wear): £300
- Total expenses: £950
Taxable trading profit: £34,000 − £950 = £33,050
Income tax: (£33,050 − £12,570) × 20% = £20,480 × 20% = £4,096
Class 2 NI (share fisherman special rate): paid at the specific weekly share fisherman rate throughout the year (a fixed weekly amount, distinct from the general Class 3 voluntary rate) — check the current published rate for the specific annual figure, as it's set and uprated separately from other NI classes.
Class 4 NI: (£33,050 − £12,570) × 6% = £20,480 × 6% = £1,229 — share fishermen also pay standard Class 4 NI on their trading profits in addition to their special Class 2 contributions, since Class 4 applies to self-employed trading profit generally and wasn't affected by the Class 2 abolition changes.
Total: income tax + Class 2 + Class 4, giving this fisherman's overall tax and NI liability, calculated through Self Assessment in the normal way alongside the specific Class 2 payment arrangement.

Share fishermen register for Self Assessment as self-employed individuals (indicating their share fisherman status, which affects how Class 2 is calculated and collected), keep records of catch shares received and deductible expenses throughout the year, and file their return by 31 January following the tax year end, alongside paying any income tax, Class 2 (share fisherman rate) and Class 4 NI owed.

What is a share fisherman for tax purposes?
A share fisherman is someone who works on a fishing vessel and is remunerated by a share of the profits or gross earnings of the catch (rather than a fixed wage), and who is self-employed rather than the vessel owner's employee. HMRC has a specific, long-standing category for share fishermen distinct from standard self-employment, primarily around National Insurance.
Do share fishermen pay a different rate of National Insurance?
Yes. Share fishermen pay Class 2 National Insurance at a higher special weekly rate than the standard Class 2 rate that applied to other self-employed people before Class 2 was abolished for most traders in April 2024 — share fishermen retain their own distinct Class 2 category and rate, reflecting entitlement to contribution-based Jobseeker's Allowance that other self-employed workers don't generally have access to.
Why do share fishermen still pay Class 2 NI when it was abolished for most self-employed people?
Class 2 NI was abolished as a compulsory charge for most self-employed people from April 2024 (with Class 4 NI now the main self-employed NI charge), but share fishermen were specifically retained as an exception, because paying the special share fisherman Class 2 rate gives them entitlement to claim contribution-based Jobseeker's Allowance during periods when fishing isn't possible (bad weather, quota restrictions, vessel repairs) — a benefit not otherwise available to the self-employed.
How is catch share income taxed as trading profit?
A share fisherman's income (their share of the catch's value, after boat running costs and other deductions specified in the crew-sharing agreement) is treated as trading income, taxed via Self Assessment like any self-employed trade — Personal Allowance, income tax bands, and deductible expenses for kit, protective equipment, and other genuine trade costs all apply in the normal way, alongside the special Class 2 NI rate.
What expenses can a share fisherman claim?
Deductible expenses include: oilskins, boots and other protective/safety equipment, certification and training courses (safety at sea, first aid), a proportion of any personal kit specifically for fishing use, and in some cases a share of vessel running costs if the crew-share agreement structures it that way rather than the boat owner bearing all vessel costs before the share is calculated.
Does the special share fisherman status apply to all fishing industry workers?
No — it applies specifically to those remunerated by a share of the catch/profits on a fishing vessel, not to salaried employees of fishing companies, processing plant workers, or fish farm employees, all of whom are typically taxed as standard PAYE employees or standard self-employed traders depending on their specific role.
