01 — OverviewExecutive Summary
Four of the 25 reforms in TICGL/TERI's Tanzania Policy Reform Agenda sit inside tax policy: a tax-policy anchor and independent dispute resolution (R3), VAT-refund discipline (R4), incentive-regime coherence (R5), and MSME formalisation alongside the payroll-cost wedge (R6). Taken together, they point to one conclusion that cuts against the usual tax-reform instinct.
Tanzania's tax problem is not that the rate is too high — it is that the rules are unpredictable and cash gets trapped. Cutting the rate would not fix either of those, and would cost revenue Tanzania cannot spare while it is trying to raise tax collection by five points of GDP.
- The rate is not the outlier. Tanzania's 30% corporate tax equals Kenya's and Uganda's; only Rwanda, at 28%, is lower — and by just 2 points.
- Predictability is the real cost. Tax rules change with each budget cycle, and dispute resolution lacks independence — taxpayers won only 9% of Court of Appeal tax cases in 2025.
- Cash flow is squeezed directly. An estimated TZS 1.4–1.5 trillion in VAT refunds remains trapped despite a 30-day rule now reported in place.
- Incentives leak revenue without buying investment. Tax breaks are scattered across the Investment Act, tax law and SEZ rules with no consolidated register to show what they cost or what they buy.
- The payroll structure is pushing the wrong way. Informal employment rose from 92.5% to 94.6% between 2020/21 and 2024 — the opposite direction from FYDP IV's 81% target — while employer-side payroll charges remain the highest of Tanzania's four EAC comparators.
Read this alongside the Tanzania Policy Reform Agenda, 2026–2031
These four tax reforms (R3–R6) sit inside the wider 25-item reform register TICGL/TERI diagnosed as necessary to meet FYDP IV — including the finding that three-quarters of that agenda needs more than stricter enforcement.

A five-point-of-GDP climb, at more than double the recent paceTax revenue reached 12.8% of GDP in FY2024/25. FYDP IV's own targets put it at 13.2% for 2025/26 and 13.7% for 2026/27, en route to 18% by 2030 — a climb of 5.2 percentage points in five years, against a recent trend of roughly 0.45 points a year. That means the required annual pace is more than double recent performance, even as TRA reports 105% collection against its 2025/26 target.
| Fiscal year | Tax revenue / GDP | Status |
|---|---|---|
| 2024/25 | 12.8% | Actual |
| 2025/26 | 13.2% | Target (TRA reports 105% collection of its own target) |
| 2026/27 | 13.7% | Target |
| 2028 (proposed milestone) | ≈14.8% | TERI-proposed linear step |
| 2030 | 18% | FYDP IV target |
A 1-percentage-point increase in tax/GDP is approximately TZS 2.1 trillion at current GDP levels (TICGL calculation).

2. Is the Tax Rate the Problem? The Regional Evidence Says No
Tanzania's rate is unremarkable — its payroll burden is notA common assumption is that Tanzania's tax rate discourages investment relative to its neighbours. The regional comparison does not support that.
| Measure | Tanzania | Kenya | Uganda | Rwanda |
|---|---|---|---|---|
| Corporate income tax rate | 30% | 30% | 30% | 28% |
| Employer-side payroll taxes (SDL, social security, workers' comp, maternity) | 14% | Nominal | 10% | 8.3% |
| Employee-side burden (income tax, social security, maternity) | 40% | 35% | 45% | 36.3% |

Regional Tax & Payroll Burden Comparison
Tanzania's corporate rate is unremarkable — level with two of three comparators. Its employer-side payroll burden (14%) is the highest of the four, and this is the cost that lands directly on the decision to formalise or hire, which is precisely the margin FYDP IV needs to move.
3. Predictability and Disputes (Reform R3)
Design flaw — rules shift yearly; disputes take years and rarely favour the taxpayerThe Presidential Tax Commission delivered 284 recommendations on 18 March 2026 — a substantial diagnostic effort. But the underlying structural problem it was responding to remains: tax rules change with each annual budget, and the dispute-resolution machinery that businesses rely on when they disagree with an assessment lacks independence and speed.
Court of Appeal Tax Cases, 2025
TICGL/TERI's recommended fix: legislate a National Tax Policy and a principal Taxation Act; keep the three-year tax-calendar practice; establish a formal tax-change consultation protocol before new measures are gazetted; and create an independent tax-appeals body separate from the revenue authority's own chain of command.
KPI: pending disputes (TZS 4.86tn) halved by 2029; appeals resolved within 12 months.
4. VAT-Refund Discipline (Reform R4)
Implementation failure — the rule exists; the legacy stock is what's trappedThis is the clearest example in the tax portfolio of a policy that is already correct on paper. A 30-day VAT-refund rule is reported for 2026/27. The problem is the legacy stock: an estimated TZS 1.4–1.5 trillion in refunds owed to businesses remains unpaid from prior periods, holding working capital that should already be back in the private sector.
Unlike the design flaws elsewhere in this analysis, R4 needs no new legislation — only enforcement of the rule already in place, plus a plan to clear the backlog. TICGL/TERI recommends enforcing the 30-day rule with interest for late payment, clearing the legacy stock on a published schedule, and releasing monthly ageing reports so progress is externally verifiable.
KPI: refund stock below TZS 0.3 trillion by FY2027/28.
5. Incentive-Regime Coherence (Reform R5)
Design flaw — incentives exist, but with no consolidated view of their costTax incentives are scattered across the Investment Act, general tax law and Special Economic Zone rules, with no single published register showing what each incentive costs the budget or what investment it is meant to buy. This is a design flaw, not an implementation gap: even perfect administration of each individual incentive would not produce a coherent, evaluable incentive system, because there is no shared framework to evaluate them against.
TICGL/TERI's recommended fix: publish a consolidated tax-expenditure and incentives register, updated annually, and align the Investment Act and SEZ rules with general tax law so incentives are granted against one consistent standard rather than three overlapping ones.
KPI: incentives register published and updated annually.
6. MSME Formalisation & the Payroll Wedge (Reform R6)
Design flaw — the cost structure works against the policy goalThis is the reform where the case for "design, not implementation" is clearest. Informal employment rose from 92.5% in 2020/21 to 94.6% in 2024 — moving further from, not closer to, FYDP IV's 81%-by-2031 target, despite active formalisation policy over that period. Stricter enforcement of the current framework, on its own, is more likely to push marginal businesses further into informality than to formalise them, because the payroll-cost wedge itself makes formalising unaffordable for small firms operating on thin margins.
If the cost of becoming formal — payroll charges, compliance overhead, licence fees — exceeds what a small business can absorb, then tightening enforcement of registration and reporting requirements raises the cost of being caught operating informally without changing the underlying economics that push a business toward informality in the first place. The fix has to touch the cost structure itself, not only the enforcement of it.
TICGL/TERI's recommended fix: a tiered MSME formalisation pathway scaled to business size; a formal review of the payroll-cost wedge; and a benefits package (banking access, procurement eligibility, social-insurance coverage) negotiated alongside formalisation, so the transition has a visible upside, not only a visible cost.
KPI: informal employment 94.6% → 93% (2028) → 81% (2031).
07 — EvidenceThe Combined Cost of Tax Unpredictability
Add the two largest trapped-capital figures in this analysis together and the scale becomes clearer: VAT refunds and disputed tax cases combined represent a substantial share of annual tax revenue sitting outside active circulation — money businesses cannot invest, hire against, or use to service debt, and revenue Government cannot yet count as collected either.
Capital Trapped in the Tax System
What this represents
- TZS 1.4–1.5tn in VAT refunds — working capital businesses are legally owed but cannot access.
- TZS 4.86tn across 1,223 disputed cases — capital neither the taxpayer nor government can treat as settled.
- A combined figure larger than the entire capital-investment line (TZS 2.33tn) in the 2026/27 national budget.
- Manager time on regulation: 14%, against 8% regionally — a direct productivity cost layered on top.
Figures are not additive claims about a single pool of money — they illustrate the combined scale of capital tied up by predictability failures across two different mechanisms.
08 — RecommendationsWhat Tax Reform Should Actually Fix
1Enforce Before You Legislate
- Clear the VAT-refund backlog on a published, monthly-reported schedule — this needs no new law, only delivery.
- Use it as the credibility-building first step before asking for patience on the slower reforms below.
2Anchor Predictability in Law
- Legislate a National Tax Policy and independent tax-appeals body through the Finance Bill 2027 cycle.
- Commit publicly to the three-year tax-calendar practice and a consultation protocol before new measures are gazetted.
3Consolidate, Don't Multiply, Incentives
- Publish one incentives register covering the Investment Act, tax law and SEZ rules.
- Tie any new incentive to a published, verifiable cost-benefit case before it is granted.
4Redesign the Formalisation Cost Structure
- Review the payroll-cost wedge alongside — not instead of — a tiered formalisation pathway.
- Pair formalisation with a visible benefits package, not only compliance obligations.
R4 (VAT refunds) is the fastest win because it requires enforcement, not legislation. R3 (predictability/disputes) and R5 (incentive coherence) belong in the next Finance Bill cycle. R6 (MSME/payroll) needs the longest runway because it requires redesigning a cost structure, not simply administering one — but the direction of the informality trend means it cannot wait for the other three to finish first.
09 — OutlookWhat to Watch
| Indicator | Baseline | Signal to watch for |
|---|---|---|
| VAT refund stock | TZS 1.4–1.5tn | Monthly ageing reports published; stock trending toward TZS 0.3tn by FY2027/28 |
| Tax disputes pending | TZS 4.86tn, 1,223 cases | Independent appeals body legislated; case backlog halved by 2029 |
| Taxpayer win rate on appeal | 9% (2025) | A rising share, signalling a less one-sided dispute process |
| Informal employment | 94.6% (2024) | A reversal toward 93% by 2028 — the trend must turn, not just slow |
| Tax revenue / GDP | 12.8% (2024/25) | 13.7% delivered in 2026/27 as budgeted, not just targeted |
| Finance Bill 2027 | Not yet tabled | Whether it carries the National Tax Policy and appeals-body provisions |
"Nobody restructures their business because a tax rate is level with the country next door. They restructure it — or stay informal, or hold back investment — because they cannot predict what the rule will be next year, or when money they are legally owed will actually arrive. Tanzania does not have a rate problem. It has a predictability problem, and predictability is a policy choice, not a function of how high the number is."

Is Tanzania's corporate tax rate too high compared to its neighbours?
No. Tanzania's 30% corporate income tax rate is exactly level with Kenya's and Uganda's, and only 2 points above Rwanda's 28%. The rate itself is not what makes Tanzania's tax environment harder to operate in than its neighbours'.
How much money is trapped in unpaid VAT refunds in Tanzania?
Approximately TZS 1.4–1.5 trillion (roughly USD 550–600 million) as of 2025, despite a 30-day refund rule reported for the 2026/27 fiscal year. This is money businesses are legally owed that remains held by government, directly squeezing their working capital.
How often do taxpayers win tax disputes in Tanzania's courts?
Taxpayers won only 3 of 33 Tax Revenue Appeals cases at the Court of Appeal in 2025 — a 9% win rate. There were 1,223 tax cases worth TZS 4.86 trillion pending on appeal as of the 2024/25 Controller and Auditor General's report.
Why does Tanzania's payroll tax structure push informality up rather than down?
Employer-side payroll charges (skills development levy, social security, workers' compensation, maternity contributions) total around 14% in Tanzania, the highest of the four East African Community comparators in this analysis. For a small or marginal business, that cost can make formalising unaffordable, which is one reason informal employment rose from 92.5% to 94.6% between 2020/21 and 2024 even as formalisation policy intensified.
What would actually fix Tanzania's tax-policy problem?
Enforce the existing 30-day VAT-refund rule and clear the legacy stock; legislate a National Tax Policy and an independent tax-appeals body; consolidate the incentive regime into one published register; and review the payroll-cost wedge alongside a tiered MSME formalisation pathway, rather than relying on stricter enforcement of the current structure.
Muhtasari kwa Kiswahili
Tatizo la Sera za Kodi Tanzania: Kwa Nini Kiwango cha Asilimia 30 Sio Tatizo. — Uchambuzi huu wa TICGL/TERI unaangazia mageuzi manne ya kodi kutoka kwenye Tanzania Policy Reform Agenda, ukionesha kwamba tatizo kuu la mfumo wa kodi Tanzania si kiwango cha kodi, bali utabiri na mtiririko wa fedha.
Kiwango cha kodi si tatizo: Kodi ya kampuni Tanzania (asilimia 30) ni sawa na Kenya na Uganda, na juu kidogo tu ya Rwanda (asilimia 28). Tatizo halisi liko kwenye michango ya mishahara upande wa mwajiri — asilimia 14, ya juu zaidi kati ya nchi nne za Afrika Mashariki zilizolinganishwa.
Fedha zilizokwama: Marejesho ya VAT yaliyokwama ni takribani shilingi trilioni 1.4–1.5, licha ya sheria ya kurejesha ndani ya siku 30. Kesi 1,223 za kodi zenye thamani ya shilingi trilioni 4.86 bado ziko kwenye rufaa, na wafanyabiashara wameshinda kesi 3 tu kati ya 33 Mahakama ya Rufaa mwaka 2025 (asilimia 9 tu).
Vivutio vya kodi vilivyotawanyika: Mfumo wa vivutio vya kikodi umetawanyika kwenye Sheria ya Uwekezaji, sheria za kodi, na kanuni za SEZ bila muunganiko — hakuna orodha moja inayoonesha gharama halisi ya vivutio hivi kwa Serikali.
Urasimishaji unaokwenda kinyume: Ajira isiyo rasmi imeongezeka kutoka asilimia 92.5 hadi asilimia 94.6 kati ya 2020/21 na 2024 — kinyume na lengo la asilimia 81 ifikapo 2031 — ikionesha kwamba muundo wa gharama za urasimishaji unahitaji kubadilishwa, si kusimamiwa kwa ukali zaidi.
Mapendekezo ya TICGL: Kutekeleza sheria ya marejesho ya VAT ndani ya siku 30 na kumaliza fedha zilizokwama; kutunga Sera ya Kitaifa ya Kodi na chombo huru cha rufaa; kuunganisha vivutio vya kodi kwenye orodha moja; na kupitia upya muundo wa gharama za mishahara sambamba na njia ya urasimishaji wa hatua kwa hatua.
- Lengo la Mapato ya Kodi: Asilimia 12.8 → 18 ifikapo 2030
- Marejesho ya VAT Yaliyokwama: TZS Trilioni 1.4–1.5
- Kesi za Kodi Zinazosubiri Rufaa: TZS Trilioni 4.86 (Kesi 1,223)
- Ushindi wa Wafanyabiashara Mahakama ya Rufaa: Asilimia 9 Tu
