Holding

The Tribunal held that the settlement payment of US$ 100,000,000 received by Heritage Oil from Tullow under the Sale and Purchase Agreement addendum was taxable business income attributable to activities in Uganda under section 79(s) of the Income Tax Act. The payment, though styled as settlement of a contingent contractual obligation, was part of the consideration for the sale of Heritage's participating interests in oil exploration blocks and constituted business profits under the Uganda-Mauritius Double Taxation Agreement. The assessment of US$ 30,000,000 was upheld as properly issued.

Outcome

Application dismissed with costs to the respondent

Facts

Heritage Oil and Gas Limited, incorporated in The Bahamas and registered as a tax resident in Mauritius, held 50% participating interests in petroleum exploration licences for Blocks 1 and 3A in Uganda's Albertine Graben under Production Sharing Agreements dated 2004. Heritage spent US$ 150,000,000 under the licences and made oil discoveries in Block 3A. On 26 January 2010, Heritage entered into a Sale and Purchase Agreement with Tullow to transfer its 50% interests. The SPA provided for an Adjusted Purchase Price plus a Contingent Amount of US$ 150,000,000, payable if the Ugandan government did not grant Tullow a tax relief within two years. On 26 July 2010, the parties executed an addendum reducing the contingent amount to US$ 100,000,000 as a settlement amount to satisfy and discharge Tullow's obligations. On 19 August 2010, Uganda Revenue Authority assessed income tax of US$ 30,000,000 on the settlement payment. Heritage objected, arguing the payment was settlement of a contractual dispute, not taxable income from immovable property or activities in Uganda.

  2. Whether the assessment for US$ 30,000,000 was proper?
  3. What remedies are available to the parties?

Orders

Rules and key headnotes

Tax Law — Non-Resident Taxation — Source Rules — Income Attributable to Activities in Uganda
Income derived by a non-resident person is taxable in Uganda under section 79(s) of the Income Tax Act where it is attributable to any activity which occurs in Uganda, including activities conducted through a branch in Uganda, even where the transaction giving rise to the income is executed outside Uganda.
Tax Law — Double Taxation Agreements — Business Profits — Permanent Establishment
Under Article 7 of the Uganda-Mauritius Double Taxation Agreement, business profits of an enterprise may be taxed in Uganda where the enterprise carries on business through a permanent establishment in Uganda, and the profits are attributable to that permanent establishment. An oil or gas well constitutes a permanent establishment under Article 5 of the Agreement.
Tax Law — Characterisation of Income — Contingent Payments — Substance Over Form
A contingent payment received as part of the consideration under a Sale and Purchase Agreement, though styled as settlement of a contractual obligation, retains its character as part of the purchase price where it was expressly provided for in the original agreement as conditional consideration dependent on specified events.
Tax Law — Contractual Rights as Assets — Capital Gains Tax
Contractual rights constitute incorporeal property and are assets for tax purposes. A payment received in respect of contractual rights under a Sale and Purchase Agreement constitutes a disposal of an asset, and the consideration received is taxable as business income where the rights arose from business activities.
Tax Law — Assessment Procedure — Commissioner's Discretion — Section 92(8) and Section 95(4) Income Tax Act
Where a taxpayer is about to leave Uganda indefinitely or cease activity in Uganda, the Commissioner General may exercise discretion under section 92(8) read with section 95(4) of the Income Tax Act to issue an assessment according to best judgment without first requiring the taxpayer to furnish a return of income, provided the discretion is exercised reasonably.
Tax Law — Assessment Validity — Defects in Form — Section 98(3) Income Tax Act
Under section 98(3) of the Income Tax Act, an assessment shall not be quashed or deemed void for want of form or by reason of mistake, defect or omission, provided it is in substance and effect in conformity with the Act and the person assessed is designated according to common intent and understanding. Citation of incorrect statutory provisions or failure to calculate in Uganda Shillings does not vitiate an assessment where the substance is correct.
Tax Law — Tax Avoidance — Legitimate Tax Planning — Colourable Devices
A taxpayer is entitled to arrange affairs to reduce tax liability within the law and may take advantage of omissions in taxing Acts. However, transactions that are shams or colourable devices designed solely to avoid tax, serving no business purpose other than tax avoidance, are not legitimate and may be disregarded in applying fiscal legislation.
