Tax Law in Transition: How Investors Should Prepare for Tanzania’s Next Five Years

Practical forecast + action plan for corporates, NGOs and foreign investors

Executive summary

Tanzania’s tax landscape is shifting decisively. The Finance Act 2025 and the 2025/26 budget package introduce new withholding regimes, tighter VAT rules linked to electronic payments, changes to tax incentives and measures aimed at broadening the tax base.

These reforms paired with ongoing digitalization of tax administration and the government’s push for local content in extractives and energy projects mean compliance will be more data-driven, quicker to detect, and costlier to fix if ignored. Corporates, NGOs and foreign investors must move from “annual compliance” to continuous tax governance.

What changed (key legal facts you must know now)

• Finance Act 2025 (effective dates staggered July–January 2025–26) introduced several significant amendments to VAT and withholding rules and tightened documentation requirements for electronic payments and VAT deductibility. These provisions are now law and already changing filing/practice expectations.
• New withholding regimes are being expanded — including measures that target retained/undistributed profits and higher withholding on certain cross-border or extractive-sector professional payments — effectively increasing immediate cash outflows for some businesses.
• VAT rules are evolving: the budget and guidance introduce different VAT treatments for electronic/B2C payments (including a 16% supply route in specific circumstances) and require proof of bank/electronic payment for certain reduced VAT treatments. The TRA is integrating invoicing and payment data to validate VAT positions.
• Digital enforcement & administration: TRA’s digital systems and mandatory integration with invoicing systems are becoming central to compliance tax authorities now expect real-time or near-real-time evidence for claimed credits and exemptions.
• Policy direction: the budget and related statements emphasize revenue mobilization and “fair contribution” across sectors (including extractives, digital platforms and informal economy formalization). This will keep pressure on loopholes and preferential regimes.

(These are the most load-bearing factual points that underpin the five-year forecast and the compliance recommendations below.)

Five-year forecast — the tax environment you should plan for

Year 1 (now → 12 months): Implementation & shock absorption

• Full effect of Finance Act 2025 measures — withholding changes, VAT procedural tightening, and electronic payment verification — will dominate compliance agendas. Expect administrative guidance and public notices from TRA clarifying operational detail.
• Cash flow pressure for firms in extractives, large services and cross-border operations as withholding and tax deposit expectations increase.

Years 2–3: Digitalization + targeted enforcement

• TRA’s digital integration (invoicing, e-filing, withholding certificates) will reduce manual claims and increase audit triggers; tax audits will rely more on matched electronic footprints. Firms with weak invoicing, bank-reconciliation or e-payment trails will experience frequent assessments.
• Sector targeting: extractives, energy (LNG, oil & gas), digital platforms and logistics will face more bespoke audits and compliance checks tied to local-content and withholding rules. Large projects (eg. LNG) will see negotiated fiscal terms, but also closer post-project scrutiny.

Years 4–5: Rationalisation & compliance sophistication

• Tax incentive rationalisation: expect consolidation of incentives (fewer, more conditional exemptions) and stronger anti-abuse checks for SEZ/EPZ benefits or TIC packages. This will push investors to prefer transparent, incentive-backed projects over opaque carve-outs.
• Local value capture: rules linking tax benefits to demonstrated local investment, employment, and tech/knowledge transfer will be enforced more strictly. Contractual and IP arrangements will be material to tax positions (e.g., local manufacture vs. importation).

Compliance priorities: what every organization must do — practical, immediate steps

For Corporates (especially extractives, energy, manufacturing, digital platforms)

1. Cash-flow modelling for new withholding rules
   • Recalculate after-tax returns and cashflow under the new withholding and undistributed-profit regimes. Factor withholding certificates and timing of VAT refunds into working capital.
2. Invoicing & payments hygiene
   • Integrate invoicing systems with bank reconciliation and preserve proof of electronic payment for supplies subject to special VAT treatment. Automate invoice capture and archival for audit trails.
3. Pre-closing tax diligence for deals
   • For M&A or asset deals, run targeted tax due diligence on withholding exposure, VAT recoverability, prior unreported liabilities and incentive carve-outs. Factor potential clawbacks into purchase price mechanics.
4. Local content & transfer pricing
   • Align tech-transfer, licensing and procurement contracts with local content commitments; document arm’s length pricing and service agreements to withstand transfer pricing scrutiny.
5. Escrow / legal protections
   • Use escrow or indemnity structures where legacy liabilities (e.g., undeclared withholding) could crystallise post-acquisition.

For NGOs & Non-profits

1. Clarify tax status and donor flow treatment
   • Confirm tax-exempt status, VAT treatment and donor reporting obligations; ensure local registration and TIN used consistently on grants and procurement.
2. Accounting for in-kind and cross-border grants
   • Document value chains and local procurement to avoid VAT or withholding surprises; some donor payments may be re-classified for withholding if routed through local suppliers.
3. Robust third-party contracts
   • Ensure vendor agreements include clear tax indemnities and tax-gross up clauses where appropriate.

For Foreign Investors & Fund Managers

1. Revisit incentive packages
   • Re-negotiate or re-confirm TIC/EPZA benefits in light of Finance Act changes; ensure written, binding approvals and compliance roadmaps.
2. Structure repatriation and profit retention
   • Plan for potential 10% measures on undistributed profits (or similar) — decide whether to repatriate, reinvest, or use permitted investment vehicles to attain more favourable tax treatment.
3. Tax governance & local advisors
   • Maintain local tax counsel and an on-the-ground tax manager to engage TRA, pre-empt queries, and implement best practice digital reporting.

Risk mitigation checklist (quick, actionable)

• Run a 30-day tax health check: VAT reconciliation, withholding certificates, bank proof for VAT claims.
• Prepare scenario cash models for 0%, 5%, 10% withholding shocks.
• Update contract templates (NDA, supplier, JV, IP license) to reflect gross-up and indemnity clauses.
• Perform transfer pricing snapshots and functional analyses for cross-border services.
• Secure TIC / regulator confirmations in writing before counting on incentives.

How Mak Africa Legal helps (practical offerings)

• Rapid Finance Act impact assessments & cashflow modelling.
• Tax-compliance remediation and TRA engagement (audit defense & voluntary disclosures).
• Structuring incentives with TIC and drafting investor protection clauses.
• Cross-border repatriation planning and withholding mitigation.
• Designing tax governance: policy, workflow, and digital record-keeping to meet TRA expectations.

Final observations

Tanzania’s tax reforms reflect a broader drive to broaden the revenue base while channeling investment into priority sectors. For investors, the objective is not to avoid tax but to manage tax strategically: anticipate timing, document rigorously, and align commercial structures with the new administrative reality. Those who treat tax as a continuous governance issue not an annual filing task will preserve value, avoid surprise liabilities, and gain government confidence for larger, long-term projects.
