Rates of Tax
Guernsey
The amount of tax a taxpayer will be liable to pay depends on their assessable income, which is the income after appropriate allowances and deductions have been applied. The standard rate of income tax is 20%, payable on net income after allowances. However, if the taxpayer receives any unauthorised payments from approved pension and annuity schemes, that income will be charged at an enhanced rate of 50%.
Guernsey residents can limit their income tax liability by making an election for a cap limit. The cap is set at £160,000 for non-Guernsey income and £320,000 for worldwide income. Additionally, individuals who purchase open market property worth over GBP 1.5 million can cap their worldwide income tax at GBP 60,000 for the first year and the next three consecutive years.

United Kingdom
In the UK, there is a comprehensive method of taxation.

Taxable Income | Bracket | Applicable tax rate |
|---|---|---|
£0 to £37,700 | Basic Rate | 20% |
£0 to £37,700 | Higher Rate | 40% |
Above £125,140 | Additional rate | 45% |

Dividend Allowance | £500 |
Marriage Allowance (Transfer of PA) | £1,260 |
Property Allowance | £1,000 |
Trading Allowance | £1,000 |

The tax year in the UK runs from April 6 to April 5. For each tax year, UK taxpayers need to submit tax returns, including their taxable income, using the SA100 form. If they have property income, they must also fill out the supplementary SA105 form.
Individuals liable to tax or with taxable income for the tax year must:
- Make a complete return of their income for that year, including any supplementary pages like the Property Income SA105 form.
- Submit the return and pay any tax due to HMRC by January 31 following the end of the tax year.
Guernsey
The tax year in Guernsey runs from January 1 to December 31. Anyone living in, working in, or receiving income from Guernsey, such as property rental income, employment income, and other income, is required to complete a personal tax return each year, unless advised in writing by the Director of the Revenue Service that they no longer need to do so. If the taxpayer has income from property letting, employment, dividends, etc., they must attach supplementary forms such as the Additional Let Property Income page, Additional Unlet Property Income page, Additional Employment Income page, and Additional Dividend Income page with the fully completed personal income tax return. The return, along with the estimated liability, must be accompanied by payment of the tax due.
The filing deadline for the submission of the return and payment of tax due to the Guernsey Revenue Service is November 30. However, the Guernsey Revenue Service has decided to reinstate the original annual filing income tax return deadline of November 30 as follows:
- For the year ended 2022: February 29, 2024
- For the year ended 2023: January 31, 2025
- For the year ended 2024: November 30, 2025

As with the individual taxes, there are significant differences in the taxation of companies in the UK and Guernsey.
Residency Status
Guernsey
All Guernsey-registered companies are generally considered tax residents of the island unless they have exempt status. From January 1, 2019, a company is deemed a tax resident in Guernsey if it is either controlled or centrally managed there in the year of charge or if it is incorporated in Guernsey without tax-exempt status.
United Kingdom
A company will be considered resident in the UK if it is incorporated in the UK or incorporated elsewhere but is centrally managed and controlled in the UK.
Tax Rates
Guernsey
Corporate resident in Guernsey are liable to tax on their worldwide income. Non-resident corporations are subject to Guernsey tax on their Guernsey-source income.
Companies pay income tax at the current standard rate of 0% on taxable income; however, income derived from certain businesses may be taxable at a 10% or 20% rate. Property income from Guernsey land, property, and buildings is subject to Guernsey income tax at 20%.
UK
Companies in the UK are taxed based on their total taxable profits at the following rates:
Band | Taxable Income | Tax Rate |
|---|---|---|
Small Profit Rate | up to £50,000 | 19% |
Main Rate | Above £250,000 | 25% |
However, if the profit is between £50,000 and £250,000, the UK resident company can claim the marginal relief to reduce the main rate of 25%.
Tax Returns and Deadlines
United Kingdom
Companies have two primary obligations to comply with legal requirements: filing annual accounts with Companies House and submitting a Corporation Tax Return (CT600) to HMRC each year. UK property rental income must be reported in the relevant section of the form, with expenses claimed accordingly. The deadlines for these obligations are as follows:
- Annual Accounts: Must be filed with Companies House within nine months after the end of the accounting period.
- Corporation Tax Return (CT600): Must be filed within 12 months from the end of the accounting period. However, the corporation tax due to HMRC must be paid within nine months after the end of the accounting period.
Guernsey
In Guernsey, the tax year runs from 1 January to 31 December. While companies can choose their own year-end, investment companies are required to compute their income and file their tax returns based on the calendar year rather than their accounting year-end. It is mandatory for all Guernsey companies to file their tax returns online.
Since companies also pay income tax on their income, the deadlines for filing tax returns are aligned with those for individuals. The deadlines are:
- For the year ended 2022: 29 February 2024
- For the year ended 2023: 31 January 2025
- For the year ended 2024: 30 November 2025
Annual Validation Submission
Additionally, every company incorporated before 1 December in a given year must file an annual validation submission online. This submission contains information current as of 31 December and must be filed between 1 January and the last day of February the following year.
Penalties: Late Filing of Return and Late Payment of Tax
If the companies fail to submit the return or annual validation by the deadlines, they will be imposed with the following penalties:
United Kingdom
Companies incur separate penalties for late filing of the accounts and late corporation tax return filing.
The penalties for late filing of corporation tax returns are as follows:
Time after your deadline | Penalty |
|---|---|
One day | £100 |
Three months | Another £100 |
Six months | 10% of the unpaid tax |
Twelve months | Another 10% of any unpaid tax |
However, there is no additional penalty for late tax payments.
The penalties for late annual accounts filing are as under:
Less than one month late | £150 |
One to three months late | £375 |
Three to six months late | £750 |
More than six months late | £1,500 |
Guernsey

Date the return is filed | Penalty imposed |
|---|---|
After the due date & up to 30 days late | Fixed penalty of £300 |
More than 30 days late | Penalty of £50 per day starting immediately after the deadline date in addition to £300 until the return is received. |

Less than one month late | £250 |
One week to One month late | £500 |
More than one month late | £1,000 |
The company will have 28 days from the date of the order to pay the civil penalty. If a company fails to pay a civil penalty, the Registrar may proceed to enforce payment as if the amount were a civil debt.
Other Taxes
Stamp Duty Land Tax (SDLT)
Guernsey does not levy any stamp duties.
In the UK, purchasing land or property involves Stamp Duty Land Tax (SDLT), with rates varying based on whether the purchaser is an individual or a company, if they are a first-time buyer and their residency status. For residential properties, the SDLT rates are structured as follows:
Purchase Price | SDLT Rate for a Single Property | Additional Rate |
|---|---|---|
Up to £250,000 | 0% | 3% |
£250,001 to £925,000 | 5% | 8% |
£925,001 to £1.5 Million | 10% | 13% |
Over £1.5 Million | 12% | 15% |
For commercial and mixed properties, the SDLT rates can be summarised as follows:
Purchase Price | SDLT Rate |
|---|---|
Up to £150,000 | 0% |
£150,001 to £250,000 | 2% |
Over £250,000 | 5% |
Where the purchaser of the property is a non-UK resident for tax purposes, there is a surcharge of 2% on top of the above rates.
Capital Gains Tax (CGT)
Capital gains are not subject to tax in Guernsey.
However, in the UK, individuals are subject to varying capital gains tax rates based on their tax bracket and the nature of the asset disposed of. The applicable rates are as follows:
Tax Bracket | Residential Property | Non-Residential Property |
|---|---|---|
Basic Rate Tax Payer | 18% | 10% |
Over than Basic Rate Taxpayer | 24% | 20% |
Companies will include their capital gains on the property as a part of their total taxable profit and pay the corporation tax on the gain.
Inheritance Tax (IHT)
There is no inheritance tax in Guernsey, whereas in the UK, there is a standard IHT rate of 40%, which is levied on the estate value which includes, private residence property, shares, cash and many more, over the threshold provided.
Also, if the gift of the property or any other gift is made prior to death, it will also be charged based on the gift type and gift value, and rates will be based on the survival of the donor after the gift, ranging from 0% to 40%. If the deceased individual has a main residence property and it is being transferred to the direct descendant, IHT can certainly be reduced as the property will qualify for Residence Nil Rate Band (RNRB) on top of Nil Rate Band (NRB).
Value Added Tax (VAT)
The Value Added Tax (VAT) provisions in these countries vary significantly.
Guernsey does not operate a VAT or goods and service tax (GST).
Meanwhile, in the UK, VAT rates range from 0% on zero-rated supplies to a standard rate of 20% on other supplies. However, hotel accommodation and specific building works are taxed at a reduced rate of 5%.
Social or National Insurance Contribution (NIC)
Guernsey
Both employers and employees are required to make social security contributions for any employed person who is over school-leaving age and under 65. These contributions are based on the employee's gross employment income.
Contribution Rates for 2024
Employees:
- Rate: 7.20% of gross earnings
- Monthly Earnings Limit: GBP 14,989.00
Employers:
- Rate: 6.90% of gross earnings
- Monthly Earnings Limit: GBP 14,989.00 per employee
Self-Employed Individuals:
- Rate: 11.90% of gross earnings
- Maximum Weekly Contribution: GBP 411.62
These rates and limits apply to earnings from 1 January 2024 onwards, ensuring that contributions are appropriately calculated and remitted based on employees' gross earnings.
United Kingdom
The payment of social insurance contributions, also known as national insurance contributions in the UK, is much more complicated than it is in Guernsey due to its income band and different tax rates.
The NICs payable in the UK are based on the threshold as follows:
NIC paid | Threshold Amount | Rate | |
|---|---|---|---|
Lower Limit | Upper Limit | ||
Class 1 Employee | £12,570 | £50,270 | 8% |
£50,271 | above | 2% | |
Class 1 Employer | £9,100 | above | 13.80% |
Class 2 | £6,725 | above | £3.15 weekly |
Class 4 | £12,570 | £50,270 | 6% |
£50,271 | above | 2% | |
Register of Overseas Entity in the UK
In August 2022, Companies House in the UK introduced the Register of Overseas Entities under the Economic Crime (Transparency and Enforcement) Act 2022. Companies House holds the Register of Overseas Entities and requires Overseas Entities that own land or property in the UK to declare their beneficial owners or managing officers.
Hence, the entities established in Guernsey and owning property in the UK need to disclose the entity and their beneficial owners or managing officers.
An entity established in Guernsey is within the scope of the Register if it holds a qualifying estate.
A 'Qualifying Estate' is a freehold estate or leasehold estate for a term of more than seven years and that was acquired:
- On or after January 1, 1999, in England and Wales,
- On or after December 8, 2014, in Scotland and
- On or after August 1, 2022, in Northern Ireland.
Entities established in Guernsey that wish to buy, sell, or transfer property or land in the UK must now register with Companies House and disclose their beneficial owners or managing officers. Where no beneficial Owners can be identified, details of Managing Officers are required.
Double Taxation Agreement (DTA)
A double taxation agreement (DTA) was signed between the two governments on October 15, 2019, to address concerns about double taxation for individuals and companies operating in both the UK and Guernsey. This agreement encompasses aspects like residency status determination, the taxation of specific types of income, and measures to prevent double taxation.
The table summarises the provisions of the treaty in force as they relate to income beneficially owned by UK residents.
Subject | Treaty Rate | Article |
|---|---|---|
Portfolio dividends | 0% | 10 |
Dividends on direct investments | 0% | 10 |
Property income dividends | 15% | 10 |
Interest | Generally, it is taxed as per the agreement unless domestic law's exemptions of the territory interfere | 11 |
Royalties | Generally, it is taxed as per the agreement unless domestic law's exemptions of the territory interfere | 12 |
Government pensions | Exempt from tax in the UK unless the individual is ordinarily resident in the UK or unless paid in respect of services rendered as a member of the Royal Guernsey Regiment | 18 |
Other pensions | Taxable only in the UK | 17 |
