If your shop, distributorship, or service business turns over between TZS 100 million and TZS 200 million a year, your tax life just got simpler — and if you have not registered with the Tanzania Revenue Authority yet, the government is now offering you a full year of income tax-free trading to come into the fold. Both changes took effect on 1 July 2026 under the Finance Act, 2026, and both reward the same thing: knowing exactly where your turnover sits.
Here is what changed, who qualifies, and the one calculation every owner in the newly covered band should run before celebrating.
What Changed on 1 July 2026
Tanzania taxes smaller businesses under a presumptive income tax regime: instead of computing profit from full books of account, you pay a flat percentage of turnover. The 2026/27 budget — a TZS 62.33 trillion package targeting 6.3% GDP growth — rewrote the two numbers that define the regime:
| Before 1 July 2026 | From 1 July 2026 | |
|---|---|---|
| Maximum turnover to qualify | TZS 100 million | TZS 200 million (roughly US$75,000–80,000) |
| Rate on turnover of TZS 11M–200M | 3.5% | 4.0% |
| Tax holiday for newly registered businesses | None | 12 months of income tax exemption |
Two details matter. First, the budget speech originally proposed a 4.5% rate, but Parliament settled at 4.0% during the Finance Bill debate — still an increase from 3.5%, so simplicity now costs a little more. Second, the new TZS 200 million ceiling deliberately matches Tanzania's VAT registration threshold, so the line where presumptive tax ends and the line where VAT registration begins are now the same line.
How the Presumptive Regime Works
Under presumptive taxation, your income tax bill is turnover multiplied by the rate — no profit computation, no depreciation schedules, no audited statements required. A business with TZS 150 million in annual sales now owes TZS 6 million in income tax (150,000,000 × 4%).
Who qualifies
The regime covers resident businesses with annual turnover between the lower bands and TZS 200 million. The headline 4% rate applies from TZS 11 million upward. If your turnover sits below the threshold, you may also opt out and file under ordinary self-assessment with audited accounts instead — an option worth pricing, as the math section below shows.
Who is excluded
The regime has never been universal. Since the Finance Act, 2022, it does not apply to independent professionals or providers of technical, management, construction, and training services. If you sell expertise rather than goods or general services, you remain under self-assessment regardless of turnover. Confirm your classification with the TRA or your accountant before assuming the 4% rate applies to you.
The New 12-Month Tax Holiday
The most generous change is aimed squarely at first-time registrants. Newly registered individual taxpayers with turnover between TZS 4 million and TZS 200 million now receive a 12-month income tax exemption, and the clock starts on the date you obtain your Taxpayer Identification Number (TIN) — not the start of the calendar year, not the date of your first sale.
Three practical implications follow:
- Time your TIN application deliberately. Because the holiday runs from the TIN date, registering just before you begin trading captures the maximum benefit. Registering months early while you are still setting up burns holiday months on zero revenue.
- The holiday covers income tax, not everything. Other obligations — withholding where you act as a collection agent, VAT if you cross the registration threshold, business licensing — continue as normal. Treat the holiday as breathing room on one tax, not a year off compliance.
- Use the year to build the records habit. Twelve months pass quickly, and the presumptive bill that follows is computed on turnover you can prove. Businesses that spend the holiday year keeping clean sales records walk into year two with an accurate, defensible tax figure. Those that do not end up reconstructing a year of turnover from memory and mobile-money statements.
Do the Math: Is 4% of Turnover Better for You?
A turnover tax ignores your margins, which cuts both ways. Under ordinary self-assessment, companies broadly face tax on profit at the standard 30% rate; under the presumptive regime you pay 4% of every shilling of sales whether you made money on it or not.
The breakeven is simple arithmetic: 4% of turnover equals 30% of profit when your net margin is about 13.3% (4 ÷ 30). That gives you a fast rule of thumb:
- Margins comfortably above 13% — many retail, distribution, and light-manufacturing businesses — will usually pay less under the 4% presumptive rate than under self-assessment, with far less paperwork.
- Margins below 13% — high-volume, low-margin trading such as staples wholesaling or agency-style businesses — may pay more under presumptive tax than on actual profit. If that is you, price the opt-out: preparing audited accounts costs money, but 4% of turnover on thin margins can cost more.
- Loss-making years get no relief under a turnover tax. Self-assessed taxpayers with genuine losses owe no income tax on profits they did not earn (and may carry losses forward); presumptive taxpayers pay 4% regardless.
Run both computations with your actual figures before the year-end, not after. The regime you want is the one that costs less over the full year, not the one with the simpler form.
A worked example
Take a Mwanza electronics retailer with TZS 150 million in annual sales:
- Presumptive tax: 150,000,000 × 4% = TZS 6,000,000. Under the old TZS 100 million ceiling, this business could not use the regime at all and had to self-assess.
- Self-assessment comparison at a 20% margin: 30,000,000 profit × 30% = TZS 9,000,000. The presumptive regime saves TZS 3 million.
- Self-assessment comparison at an 8% margin: 12,000,000 profit × 30% = TZS 3,600,000. Here self-assessment would save TZS 2.4 million versus the presumptive bill.
Same turnover, opposite answers. Your margin decides.
What to Do Now: A Checklist for Owners
1. Pin down your trailing-twelve-month turnover. The TZS 200 million line is now the most important number in your tax life. Add up the last twelve months of sales — every branch, every channel, mobile money included. If you sit between TZS 100 million and TZS 200 million, you are newly eligible for the simplified regime.
2. If you are unregistered, weigh registering now. The 12-month holiday from the TIN date is explicitly designed to pull informal businesses into the tax net. Factor in the full compliance picture — licensing, record-keeping, future VAT registration at TZS 200 million — but do not leave a year of income tax exemption on the table through inertia.
3. Watch the VAT threshold. With both thresholds now at TZS 200 million, crossing the line changes two regimes at once: you exit presumptive tax into self-assessment and enter VAT registration territory. Businesses approaching TZS 180 million-plus should forecast quarterly, because an unexpectedly strong quarter can push you over with no time to prepare.
4. Keep records even though the regime is "simple." Presumptive tax removes the profit computation, not the need to evidence turnover. Keep daily sales records, bank and mobile-money statements, and purchase invoices — the docs show how to structure them as a plain-text ledger you fully control. If the TRA ever queries your declared turnover, till records beat estimates.
5. Know about the new settlement window. Alongside the rate changes, the Finance Act introduced a 90-day window for out-of-court tax settlement. If you carry a legacy dispute, that window — plus professional advice — may resolve it faster than litigation.
6. Revisit the choice annually. Margins move. A business that was better off under presumptive tax this year may not be next year. Make the presumptive-versus-self-assessment comparison part of your year-end routine.
Common Mistakes to Avoid
- Assuming the holiday is automatic. It attaches to newly registered individual taxpayers in the qualifying turnover band. If you were already registered, or you trade through a structure outside the holiday's scope, do not simply stop paying — confirm eligibility first.
- Ignoring the rate rise. Businesses that already paid 3.5% will pay 4% on the same turnover — a roughly 14% increase in the tax bill. Budget for it rather than discovering it at filing time.
- Letting turnover surprise you. The most expensive mistake is drifting past TZS 200 million without noticing and facing self-assessment plus VAT registration unprepared. Monthly turnover tracking is the cheapest insurance in this regime.
- Treating "presumptive" as "no books." The regime simplifies the tax computation, not your business. Owners who cannot state monthly turnover cannot manage stock, credit, or cash flow either.
