Residence and the income base come before the rate
Article 123 of the Income Tax Law treats Jersey-incorporated companies as resident, subject to the specified foreign-residence and management exception. A company incorporated elsewhere is resident when its business is managed and controlled in Jersey. Article 61’s Schedule D charge reaches resident income from activity and property inside or outside Jersey.
This is why “zero tax” and “territorial tax” are not synonyms. The ordinary rate may be zero while the company remains resident and has worldwide income within the system. An owner who moves to Jersey must also revisit the residence of an existing foreign company; the old incorporation certificate is not the complete answer.
Identify the activity before selecting a tax rate
Jersey’s ordinary company rate is 0%, with defined exceptions. Financial-services companies within the statutory definition can be charged at 10%. Utilities and specified Jersey property income are among the 20% categories. Large retail operations have their own turnover and profit tests; a small online business should not borrow a rate from an unrelated regulated sector.
Analyse each revenue stream and the legal entity earning it. A company with several activities may need more than one treatment. For a proposed acquisition, review historic returns, residence positions and tax attributes as well as the purchase price.
| Category | Headline treatment | What needs checking |
|---|---|---|
| Ordinary company income | 0% standard rate | Confirm no special rate applies |
| Defined financial services | 10% | Use the statutory activity definition |
| Utilities / specified Jersey property income | 20% | Property ownership is not sheltered by ordinary 0% |
| Large retail business | Specific regime, up to 20% | Check Jersey turnover and profit bands |
Multinational groups need a separate Pillar Two analysis
The Multinational Corporate Income Tax regime is separate from the familiar 0/10/20 discussion. Revenue Jersey’s guidance addresses in-scope groups with global revenue of at least €750 million and Jersey constituent entities, including exemptions and detailed GloBE computations. In-scope Jersey entities are charged at 15% on the relevant GloBE-income base; the Income Inclusion Rule also requires consideration.
A small company can belong to a large group. Test the ownership and consolidation perimeter before dismissing these rules based only on the Jersey entity’s own turnover. Do not substitute accounting profit multiplied by 15% for the statutory computation.
Governance must describe the real business
Relevant entities and relevant activities can fall within economic-substance requirements. The corporate return asks about the activities, board meetings and strategic decisions. These are operational questions: identify who has authority, where it is exercised and what people, expenditure and premises support the revenue-generating activity.
For implementation, build an evidence schedule alongside the operating model. It should identify decision responsibilities, record retention, local resources and escalation when the business changes. We can assess requirements and connect clients with independent management providers where appropriate; we do not supply foreign management and control internally.
GST registration, pricing and returns
The standard GST rate is 5%. Mandatory registration turns on taxable turnover of at least £300,000 in a twelve-month period, including expected turnover; it is not a £300,000 profit test. Voluntary registration below the threshold can allow recovery of eligible input GST but introduces charging, record-keeping and return obligations.
For a standard-rated sale priced at £1,000 before GST, the customer pays £1,050. If a quoted consumer price is fixed at £1,000 including GST, its tax component is £47.62 (£1,000 × 5/105), leaving £952.38 before other costs. These examples assume registration and a standard-rated supply.
| Task | Requirement |
|---|---|
| Register | Obtain the business income-tax reference and complete the GST registration. |
| Classify supplies | Distinguish standard-rated, zero-rated and exempt supplies, including imports. |
| File | Quarterly return, due by the last day of the following month. January–March is due 30 April. |
| Keep evidence | Record sales, expenses, imports and the basis of the GST treatment. |
Model the owner and maintain the result
The final comparison should include corporate income, payments to the owner, contributions, the cost of genuine operations and any remaining foreign tax. The owner’s salary and distributions require their own personal analysis. Another country may still tax a permanent establishment, apply CFC rules or challenge profit allocation.
Set a recurring review around actual changes: a director’s move, new staff abroad, a different revenue line, property acquisition or a major group transaction. Keep company filings and substance evidence on the same calendar as the owner’s personal returns so that the two accounts of the business remain consistent.
What an £8,000 monthly salary costs
For an ordinary monthly Class 1 employee earning £8,000, employee Social Security is £363.72 and employer Social Security is £442.48. The salary plus employer contribution is £8,442.48. The employee has £7,636.28 before income tax, long-term-care deductions and any other deductions. This is a contribution example, not a take-home-pay quote.
The employer calculation is £6,062 × 6.5%, plus £1,938 × 2.5%. Bonuses, back pay and leaving payments can change the payroll period calculation. Jersey’s employer guide rounds monthly earnings down to whole pounds and weekly earnings down to the nearest 25 pence; do not use a generic UK National Insurance engine.
| Payroll component | Example |
|---|---|
| Contractual gross salary | £8,000.00 |
| Employee Class 1 | £363.72 |
| Employer Class 1 | £442.48 |
| Employer cash cost before other employment costs | £8,442.48 |
| Employee balance before tax/LTC/other deductions | £7,636.28 |
Prepare payroll before the first payment
Record each employee’s contribution category, Social Security details and applicable tax deduction information. Build the payroll return from actual pay, not a notional annual average. Reconcile the employee deduction and employer charge separately, and keep the calculation supporting any adjustment.
Class 1 payments are due within 15 days after the end of the month. A complete employment budget also needs contractual benefits, leave, pension arrangements where applicable and local employment-law obligations. The Social Security example above does not estimate those items or resolve an owner-director’s Class 2 classification.
