If you are challenging a Tanzania Revenue Authority (TRA) tax assessment, knowing exactly when the Tax Revenue Appeals Board (TRAB) has jurisdiction to hear your case is critical. A recent Court of Appeal of Tanzania decision, Motor Hub East Africa Limited v. Commissioner General, TRA, Civil Appeal No. 192 of 2025 — reinforces a strict procedural rule: TRAB can only hear appeals arising from a valid objection decision. Get this wrong, and your appeal may be dismissed for want of jurisdiction, no matter how strong your case is on the merits.

This article breaks down the ruling, its background, and what taxpayers need to do to protect their right to appeal.

1. Introduction:
TRAB's Jurisdiction Over Tax Appeals in Tanzania

The scope of TRAB's jurisdiction to entertain appeals arising from the administration of Tanzania's revenue laws has been tested before the Court of Appeal of Tanzania (the "Court") on multiple occasions, most recently in Motor Hub East Africa Limited v. Commissioner General, Tanzania Revenue Authority, Civil Appeal No. 192 of 2025, the decision this analysis is based on.

In the well-known Pan African Tanzania Limited cases (Civil Appeals No. 121 of 2018 and No. 172 of 2020), the Court confirmed that TRAB's jurisdiction is confined to appeals arising from objection decisions issued by the Commissioner General of the Tanzania Revenue Authority.

More recently, in Wilbert Basilius Kapinga v. Commissioner General, Tanzania Revenue Authority, Civil Appeal No. 145 of 2022, the Court went further, holding that TRAB also has jurisdiction over appeals arising from the TRA's failure to act within prescribed statutory timelines (administrative inaction). This is treated as an "omission" under Section 64(1) of the Tax Administration Act, Cap. 438 R.E. 2023.

2. Background of the Case

Motor Hub East Africa Limited (the "Appellant") was audited by the TRA for the 2018 year of income. Among other adjustments, TRA proposed to:
• Disallow drawings amounting to USD 600,000, and
• Re-characterize understated payables of USD 492,141 as revenue.
Following the audit, TRA issued an adjusted assessment reflecting an additional tax liability of TZS 755,574,035.

The Appellant objected, challenging the disallowance of drawings. In response, TRA issued:
1. A proposed determination of the objection, and
2. A rectification letter correcting an error on the face of the record, the original adjusted assessment had omitted the understated payables adjustment — revising the tax liability upward to TZS 1,390,564,232.
3. A final notice of determination reflecting this revised position.

The Appellant challenged both the final determination and the rectification letter before TRAB, which partially allowed the appeal.

TRA then appealed to the Tax Revenue Appeals Tribunal (TRAT), arguing TRAB had no jurisdiction to entertain an appeal on the rectification letter because it was not, itself, an objection decision. TRAT agreed with TRA. The Appellant then escalated the matter to the Court of Appeal as Civil Appeal No. 192 of 2025.

3. The Legal Question Before the Court.

The central issue in Civil Appeal No. 192 of 2025 was:

Did the rectification letter amount to an "objection decision" capable of being appealed to TRAB?

4. The Court of Appeal's Decision

The Court held that TRAB's appellate jurisdiction is strictly confined to objection decisions, and an objection decision only exists where there was a corresponding objection against that specific item.

Because the rectification letter introduced a new item (the understated payables adjustment) that the Appellant had never separately objected to, the Court ruled that:
• The correct procedure was to lodge a fresh, separate objection against the rectification letter, and
• Since the Appellant failed to do so, TRAB had no jurisdiction to entertain the appeal on the TRA's treatment of the USD 492,141 understated payables.

5. Key Takeaways for Taxpayers

• Procedural compliance is everything. This decision is a strong reminder that strict procedural adherence is required before lodging an appeal with TRAB.
• No objection, no jurisdiction. TRAB's jurisdiction depends entirely on the existence of a valid objection decision, without it, the Board simply cannot hear the appeal, regardless of the merits.
• New items require new objections. If TRA introduces a new adjustment via a rectification letter (or similar correction), taxpayers must lodge a separate, timely objection against that specific item to preserve their appeal rights.

Frequently Asked Questions

Q: What is an objection decision under Tanzanian tax law? An objection decision is TRA's formal response to a taxpayer's notice of objection against an assessment. It is the trigger that gives TRAB jurisdiction to hear an appeal.

Q: Can TRAB hear an appeal if TRA never issued an objection decision? Generally, no except where the TRA fails to act within the statutory timeline, which is treated as an "omission" under Section 64(1) of the Tax Administration Act, Cap. 438 R.E. 2023, and can itself be appealed.

Q: What should I do if TRA issues a rectification letter introducing a new adjustment? Lodge a fresh, separate notice of objection specifically against the new item in the rectification letter. Relying on your original objection is not sufficient.
