Alderney is part of the Bailiwick of Guernsey for the purposes of taxation and has a reciprocal agreement with Jersey and the U.K.
In Alderney there is:
- NO Value Added Tax.
- NO tax on capital.
- NO tax on inheritance.
- NO tax on exempt companies carrying on business outside the islands-see section Trusts/ Company Law.
- NO tax on trusts whose beneficiaries live outside the island
- LOW tax (only 20%) on profits of companies which carry on business in the island.
- LOW tax (20%) and generous personal allowances on income of persons who live in the island.
- PREFERENTIAL arrangements made for captive insurance companies based in the island.
Professional advice from a tax consultant familiar with Guernsey/ Alderney tax laws is strongly recommended.
It should be noted that pensions and other income left in the U.K. continue to attract U.K. tax although a double taxation agreement ensures that further tax is not paid.
A flat rate of 20% is levied after personal allowances which are generous by U.K. standards.
