Tanzania Finance Act 2026: The Mining & Infrastructure Realignment

De-Risking Inbound Capital by Aligning Framework Agreements with Primary Statute

The Tanzania Finance Act 2026 has introduced a major legislative fix to close the historical gap between what a Cabinet-approved Framework Agreement promised an investor and what the revenue authority actually allowed at the border.

Historically, even when major foreign direct investment (FDI) projects successfully negotiated sovereign stabilization clauses and custom exemptions, the Tanzania Revenue Authority (TRA) would routinely disallow them during audits or at the port. The revenue authority’s rationale was simple: a negotiated contract, no matter how high-level, did not constitute an explicit statutory provision or a gazetted Government Notice (GN).

By amending four core pieces of primary tax legislation, the state has formally aligned the statute book with sovereign contract commitments.

The Core Legislative Fix: Statutory Codification

Instead of leaving tax exemptions to administrative discretion, the Finance Act 2026 cuts through four separate revenue statutes, embedding clear, binding language directly across the country’s tax frameworks:

• The Excise Duty Act — The New Section 146B: Expressly empowers the Minister, upon Cabinet approval, to waive excise duty on goods imported or purchased for mining activities by holders of a Mining Licence (ML) or Special Mining Licence (SML) where the Government holds an ownership interest.

• The Value Added Tax Act: Formally integrates institutional VAT relief mechanisms directly tied to Cabinet-approved Framework Agreements, mandating a streamlined application path directly through the Commissioner General.

• The Income Tax Act & The Road and Fuel Tolls Act: Parallel statutory updates ensure that stabilized corporate income metrics and logistical toll structures mirror the exact terms agreed upon in the master framework.

The Technical Takeaway: This realignment transforms stabilization clauses from political promises into black-letter law. The contract and the statute now point the exact same way. This provides international project financiers, development finance institutions (DFIs), and sovereign wealth funds with genuine legal certainty at customs.

The Strategic Boundaries of the 2026 Exemptions

This tax alignment is not an open-ended fiscal giveaway; it is a precisely calibrated relief window designed to support projects during their most capital-intensive phases. Investors must note three strict statutory boundaries:

┌────────────────────────────────────────────────────────────────────────┐
│                      CALIBRATED RELIEF LIFECYCLE                       │
└───────────────────────────────────┬────────────────────────────────────┘
                                    │
                  ┌─────────────────┴─────────────────┐
                  ▼                                   ▼
       [ CONSTRUCTION PHASE ]               [ PRODUCTION PHASE ]
    • Negative cash flow window          • Commercial extraction begins
    • STATUTORY EXEMPTIONS ACTIVE        • TAX INCENTIVES AUTOMATICALLY EXPIRE
    • Cores: VAT & Excise relief         • Excludes all petroleum products

1. The Construction Phase Lock: The newly codified exemptions apply strictly during the construction phase of the project. The exact moment commercial mineral production or infrastructure operations begin, the statutory relief windows close automatically.

2. Petroleum Product Exclusion: Fuel and lubricants are explicitly carved out from these statutory remissions. Standard road, fuel, and excise duties on petroleum products remain fully payable, protecting the state’s energy sector revenues.

3. The Master Register Prerequisite: To enjoy these statutory protections, all existing and newly concluded Framework Agreements must be formally registered in the Minister’s official Register of Tax Agreements.

Enforcement and the New Anti-Avoidance Architecture

To protect the integrity of the expanded tax base, the state has paired these statutory protections with aggressive enforcement tools. The Finance Act 2026 introduces the new Section 94A of the Tax Administration Act.

This section imposes severe administrative and criminal penalties on corporate entities that:

• Misuse framework-based exemptions for unapproved works.

• Transfer exempted capital goods or equipment to third parties without the written permission of the Commissioner General.

• Utilize fraudulent procurement schemes to artificially inflate construction-phase costs.

Sophisticated capital should welcome this enforcement architecture rather than fear it. A regulatory regime that strictly polices the abuse of an exemption is a regime that intends the exemption to mean something. Loose administration and unpredictable, retroactive revocations are the exact patterns that historically damaged regional credibility. Clear enforcement boundaries, paired with statutory certainty, create a stable investment climate.

The Corporate Action Plan for Boards and Legal Counsel

To ensure inbound capital projects are properly insulated under the current fiscal regime, corporate project teams should immediately deploy a three-part compliance review:

1. Retroactive Alignment Review

Audit existing Framework Agreements concluded prior to July 1, 2026. Verify whether your specific construction-phase tax exemptions are currently listed in the Minister’s Register of Tax Agreements to ensure your protections carry over into the new statutory regime.

2. Cost-Base Safeguards for Associates

Analyze related-party transactions in light of the updated cost-base rules. The current framework tightens anti-avoidance measures for asset transfers between associates. It locks the cost base of subsequently disposed assets to the original acquisition cost rather than an inflated transfer price. This effectively stops the practice of using exempt intra-group transactions to achieve a stepped-up cost base.

3. Subcontractor Disclosure Interfacing

Update corporate reporting timelines to comply with the new strict disclosure windows. All extractive and construction operations must now submit comprehensive registers detailing the names, exact contract values, clear scope of works, and duration of all subcontracted entities within 30 days of the commencement of works (accelerating the old timeline, which ran from the execution of the contract).
