Civil Reference No. 7 of 2004
The appellant, Panafrican Energy Tanzania Ltd, is a company engaged in the production and supply of natural gas. In its 2009 financial return, it claimed depreciation allowance on wells SS10 and SSW (the Assets) amounting to USD 9,294,832. The respondent, the Commissioner General (TRA), disallowed this depreciation expenditure via Assessment No. 420700898, on the ground that although the appellant owned the Assets (satisfying one condition under s.17 of the Income Tax Act, 2004), the Assets were not employed in the production of the appellant's income during the relevant year, as required by the second condition of that section. The appellant's objection failed, and its appeal to the Tax Revenue Appeals Board was dismissed on the basis that, although the wells fell under Class 4 depreciable assets per the Third Schedule, they were not used in production of income for 2009. A further appeal to the Tax Revenue Appeals Tribunal was also dismissed, prompting this appeal to the Court of Appeal.
Whether the Tax Revenue Appeals Tribunal erred in law by interpreting section 17 of the Income Tax Act, 2004 in isolation of paragraph 1(3) of the Third Schedule to the Act, particularly as applicable to oil and gas exploration companies; and, correspondingly, whether the Tribunal erred in upholding the disallowance of depreciation allowance on capital expenditure of USD 9,294,832 incurred in drilling and constructing Wells SS10 and SSW, on the basis that the Assets were not employed in production of the appellant's income for 2009.
The appellant, through Mr. Bhojani, argued that section 17 must be read together with paragraph 1(3) of the Third Schedule, which treats expenditure on natural resource prospecting, exploration and development as if incurred in securing an asset used in production, and that the word 'employed' in section 17 should be interpreted in the context of the inherently risky oil and gas industry such that the Assets should be deemed used even absent actual use in 2009. He relied on the phrase 'to the extent not otherwise provided' in paragraph 1(3) and comparative law from Australia (accelerated depreciation under its Income Tax Act 1997) and India (block asset concept permitting depreciation once an asset is ready for use), urging the Court to draw inspiration from those regimes. Alternatively, he argued: (i) depreciation had been allowed in 2007 and 2008, so disallowance in 2009 was unjustified; (ii) depreciation was allowable under Article 13 of the Production Sharing Agreement with the Government; (iii) the Assets, though drilled in 2007 as spare wells, were used to analyze data for production forecasting and thus were 'employed'; and (iv) even if not qualifying under Class 4, the Assets qualified under Class 7 of the Schedule. The respondent, through Mr. Beleko, argued that section 17 imposes two independent, universally applicable conditions—ownership and actual use in production of income—which the parties agreed the Assets did not meet in 2009. He contended the Third Schedule, including paragraph 1(3), merely sets out classes and computation of allowances and is not itself a basis for claiming deduction absent satisfaction of section 17. He distinguished the Australian and Indian regimes as resting on express statutory mechanisms (capped-life deduction; block-asset concept) not present in Tanzanian law. On the alternative arguments, he submitted that prior allowance in 2007/2008 could not estop the Commissioner from correctly applying the law to a later year, that the Production Sharing Agreement could not override the Act, that the 'in-use' argument regarding data analysis was raised too late as it was not disputed before the Board, and that Class 7 assets remain subject to the same section 17 conditions.
The Court of Appeal dismissed the appeal with costs, holding that section 17 of the Income Tax Act, 2004 requires depreciable assets to be both owned and actually employed/used in the production of income during the relevant year, and that paragraph 1(3) of the Third Schedule, properly construed, does not dispense with the 'used' requirement—it merely deems qualifying expenditure to be incurred in securing an asset that is used in that production. Since the Assets were not used in production of income in 2009, they did not qualify for depreciation allowance. The Court rejected reliance on Australian and Indian law, finding those jurisdictions operate under materially different statutory schemes (capped-life deduction and block-asset concepts, respectively) not present in Tanzanian law. On the alternative arguments, the Court held that prior allowance of depreciation in 2007 and 2008 could not estop the Commissioner, since estoppel does not operate against performance of a statutory duty; that the Production Sharing Agreement could not override the mandatory provisions of the Act; that the claim regarding use of the Assets for data analysis could not be raised for the first time on appeal, having not been disputed before the Board; and that Class 7 assets remain subject to the same section 17 conditions as Class 4 assets, so reclassification would not assist the appellant.
The judgment clarifies that under Tanzanian tax law, section 17 of the Income Tax Act, 2004 imposes two cumulative and mandatory conditions—ownership and actual use in production of income—for depreciation allowance, and that paragraph 1(3) of the Third Schedule (specific to natural resource prospecting, exploration and development expenditure) does not create an exception dispensing with the actual-use requirement; it merely deems qualifying expenditure to relate to an asset used in production. The decision confirms that comparative foreign tax regimes (such as Australia's capped-life depreciation or India's block-asset concept) cannot be imported into Tanzanian law absent equivalent express statutory provisions. It also reaffirms the established principle that estoppel does not operate against a public authority performing a statutory duty, meaning inconsistent treatment of a taxpayer in prior tax years does not bind the tax authority in later years. The case is significant for oil and gas and other extractive industry taxpayers in Tanzania regarding the strict conditions for claiming depreciation allowances on capital assets not actually used in production during the relevant year.
