Non-residents: income from employment exercised on the island, wherever paid; business income attributable to activity there, including through a permanent establishment; and property income paid by a resident, deducted by a permanent establishment, or from property on the island (s.2). Tax Guide 12 states that tax is charged only on income earned in Saint Helena. Section 50 still gives a credit where a resident is liable on foreign-source income.
Transfer pricing: s.78 is the only rule. An associate is any person who acts or may act on the other's directions, including a spouse or child. The Ordinance prescribes no documentation or country-by-country report. Section 79 lets the Commissioner disregard or recharacterise a scheme with a main purpose of tax avoidance, or a transaction without substantial economic effect.
Customs: HM Customs controls imports and exports at Jamestown, Rupert's and the airport. The revenue it collects is based on import taxes; the page says the market does not allow for export tariffs. Liquor duty and excise also apply (HM Customs page).
Foreign tax credit: apply in writing with all information needed, including any refund of the foreign tax (s.50(2)). A later refund of foreign tax is repayable within 30 days (s.50(4)).
Leaving: file at least 14 days before departure if s.37(3) applies. The Commissioner may demand tax early if a person may leave without paying (Regulation 24).
Withholding: deduct when paying, remit within 15 days after month end, give a certificate at payment.
Imports: classify the goods on the tariff, then enter them with HM Customs. Customs opens Mondays to Fridays 09:00 to 15:00.
Land: duty on a transfer is payable under the Stamp Duties Ordinance. The additional 2.5% is refunded if the only other home is sold within six months. First home relief is clawed back on specified events within five years.
Failure to deduct withholding: s.69, on top of the tax. Late remittance: 10% plus 1% a month (s.67). A s.78 adjustment that shows a false statement can lead to s.68 penalties.

Not yet confirmed: Double tax arrangements. Any withholding on non-resident dividends, royalties or fees: the Ordinance's withholding Part covers deposit interest only, and no other was found. The 2026 customs duty changes on alcohol, tobacco and vaping (ExCo Memo 05/2026): outcome not read, so the July 2025 tariff may be out of date on those lines. Diesel exemption extended to 31 March 2028 by ExCo approval; the order itself was not read. Excise tariffs and Liquor Duty rates. Stamp duty exemptions and the footnote stating the consolidation is authoritative at 1 April 2019 though it carries L.N. 23 of 2025.
