Civil Reference No. 7 of 2004
The dispute originated from a VAT Tax Appeals case in which the respondent (Commissioner General, Tanzania Revenue Authority) issued an additional VAT assessment against the appellant, Insignia Limited, in the sum of Shs. 1,252,893,687/= for underpayment of Value Added Tax. The appellant objected and appealed under section 16(2)(a) of the Tax Revenue Appeals Act 2000. The Tax Revenue Appeals Board reduced the additional tax payable to Shs. 37,214,114/= with interest. Dissatisfied, the respondent appealed to the Tax Revenue Appeals Tribunal, which reversed the Board and held that the appellant was liable for the full additional VAT of Shs. 1,252,893,687/=, relying on exhibits RE2, RE3 and RE4 seized from the appellant's premises during a revenue authority investigation. The appellant then appealed to the Court of Appeal of Tanzania.
(1) Whether the Tribunal erred in law by holding that exhibits RE2, RE3 and RE4 represented actual sales (a factual matter, since the appellant argued these figures included business projections rather than actual sales). (2) Whether the Tribunal erred in law regarding the allocation and discharge of the burden of proof under section 18 of the Tax Revenue Appeals Act, Cap. 408 R.E. 2002, specifically whether the appellant discharged its burden of proving the assessment was excessive or erroneous, and whether the respondent bore any evidential burden once the appellant produced evidence disputing the assessment. A threshold issue was also whether, under section 25 of the Tax Revenue Appeals Act, the Court of Appeal could entertain grounds that were essentially factual rather than legal.
The appellant, through Mr. Matunda, argued that the respondent wrongly relied on exhibits RE2, RE3 and RE4 as representing actual sales, when they in fact included business projections/targets, and that there was no evidence these targets constituted actual sales; thus the Tribunal's findings were not based on cogent evidence and the Court should make its own findings. On the burden of proof, the appellant argued that the evidential burden lay on the respondent to justify its assessment, particularly since the appellant called six witnesses (including its Managing Director) to discharge its burden under section 18(2)(b), and since the respondent had seized all relevant documents and had a resident employee at the appellant's premises, placing the respondent in a better position to correctly assess the tax. The respondent, through Mr. Beleko, argued that the burden of proof rested on the appellant taxpayer, that the authenticity of the exhibits was not disputed, and that only questions of law could be canvassed before the Court of Appeal, not factual questions such as whether the exhibits represented actual sales.
The Court held that, under section 25 of the Tax Revenue Appeals Act, appeals to the Court of Appeal from the Tribunal lie only on questions of law, and the appellant could not reopen factual issues. Accordingly, the first and fourth grounds of appeal (concerning whether exhibits RE2, RE3 and RE4 represented actual sales) were factual matters not properly before the Court and were not sustained. However, the second and fifth grounds, concerning interpretation of the burden of proof under section 18 of the Tax Revenue Appeals Act, raised a question of law. The Court affirmed that under section 18(2)(b), the onus is on the taxpayer to prove that an assessment is excessive or erroneous, and the revenue authority bears no initial burden. However, once the taxpayer produces documents or evidence giving a reasonable explanation, the taxpayer is regarded as having discharged that onus, and the evidential burden then shifts to the revenue authority to justify the assessment; if the revenue authority fails to do so, the assessment must be vacated. The Court found that the respondent had seized the appellant's documents and used them to compute the VAT liability, and that the appellant had made out a prima facie case, shifting the evidential burden to the respondent to substantiate the assessment with direct or documentary evidence, not merely a presumption. Since the Tribunal improperly placed the entire burden on the appellant despite this shift, the Court allowed the appeal with costs and set aside the Tribunal's decision of 15 September 2006.
The judgment clarifies the operation of the burden of proof in tax disputes under section 18(2)(b) of the Tax Revenue Appeals Act, Cap. 408 R.E. 2002, affirming that while the initial onus is on the taxpayer to show an assessment is excessive or erroneous, this burden is not static: once the taxpayer provides a reasonable explanation or evidence, the evidential burden shifts to the revenue authority to justify the assessment with direct or documentary proof. The Court also reinforced the jurisdictional limitation under section 25 of the Act that appeals to the Court of Appeal from the Tax Revenue Appeals Tribunal are confined to questions of law, precluding re-litigation of factual findings. The decision draws on established tax law authorities (T. Haythornwaite & Sons Limited v. Kelly and Richard A. Toby's treatise) to articulate the shifting burden principle, providing guidance for future tax appeals on the interplay between statutory burden-of-proof provisions and evidentiary shifting in revenue assessment disputes.
