Presumptive Tax in Tanzania Explained for Small Traders (2026)

If you run a duka, a salon, a hardware shop, a boda business or a small workshop, you almost certainly pay tax under Tanzania's presumptive regime — even if nobody has ever explained it to you. Presumptive tax is the simplified system for small resident traders. Instead of working out your profit, deducting expenses and filing full accounts, you look up your annual turnover in a table and pay the figure next to it.

The Finance Act, 2026 rewrote that table with effect from 1 July 2026. The ceiling doubled, the top band became a flat percentage, and new businesses gained a twelve-month exemption that you have to ask for. If you are trading in Tanzania today, the rules you were told about in 2024 are out of date.

What presumptive tax actually is

Under the Income Tax Act, Cap. 332, a qualifying resident individual's income tax for the year is simply the amount of presumptive income tax set out in the First Schedule table. It replaces the normal calculation entirely. You are not taxed on profit; you are taxed on a figure derived from turnover.

Turnover means your gross sales for the year — everything that came in from the business before you paid for stock, rent, transport or anything else. This is the single most misunderstood point in the whole regime, and we come back to it below, because for a low-margin business it can matter enormously.

The trade-off is deliberate. You get a system you can understand without an accountant. The TRA gets a system it can administer across hundreds of thousands of small traders. Neither side pretends it produces a perfectly accurate result.

Do you qualify? Three conditions, not one

Most traders know about the turnover limit and assume that is the whole test. It is not. Paragraph 2(1) of the First Schedule sets three conditions, and you must meet all of them.

Your income must consist exclusively of business income sourced in Tanzania. This is the condition that quietly disqualifies people. If you run a shop and hold a salaried job, or and collect rent on a room you let out, or and earn from a foreign client, your income is no longer exclusively business income and the presumptive regime does not apply to you. You fall back to the normal rules. If you have a salary alongside your trade, our guide to understanding your payslip explains how PAYE is worked out on the employment side.

Your turnover must not exceed the threshold, which the Finance Act, 2026 raised from TSh 100 million to TSh 200 million a year.

You must not have elected to disapply the provision for that year. The law gives you a right to opt out. Almost nobody uses it, and for some businesses that is an expensive oversight.

The 2026 table: what you pay

The table has two columns, because the law rewards traders who keep proper records under section 43 of the Tax Administration Act. Records means real books: sales records, purchase receipts, EFD receipts and bank statements, kept for the period the law requires.

For the top band the Act sets a single figure — 4% of turnover — rather than two competing ones. Note also that record-keeping is a legal duty in its own right under the Tax Administration Act, not merely a way to reduce this particular bill.

Why keeping records cuts your bill

The two columns are not a rounding difference. Work through them.

Turnover TSh 6,000,000. With records: 3% of the TSh 2,000,000 above the threshold, so TSh 60,000. Without records: TSh 100,000. Keeping a sales book saves TSh 40,000.

Turnover TSh 9,000,000. With records: TSh 90,000 plus 3% of TSh 2,000,000, so TSh 150,000. Without records: TSh 250,000. Records save TSh 100,000.

Turnover TSh 11,000,000. With records: TSh 90,000 plus 3% of TSh 4,000,000, so TSh 210,000 — an effective rate of about 1.9% of turnover.

A TSh 100,000 saving on a TSh 9,000,000 business is roughly what an exercise book and an hour a week costs you. It is one of the highest-return habits available to a Tanzanian small trader, and it feeds into everything else: knowing your real margin, budgeting for slow months, and being able to show a lender what the business actually earns when you apply for business finance.

The cliff at TSh 11 million

Look closely at the boundary. A trader with proper records and turnover of exactly TSh 11,000,000 pays TSh 210,000. A trader with turnover of TSh 11,000,001 falls into the flat band and pays 4% of the whole turnover — about TSh 440,000.

Crossing that line by one shilling roughly doubles the tax. This is a real feature of the table, not an error, and it is worth understanding for two reasons. First, if you are trading close to TSh 11 million, know that the step exists so it does not ambush you. Second, and more importantly, do not let it tempt you into under-declaring. Understating turnover to stay under a band is an offence, the penalties dwarf the saving, and EFD records make sales far more visible than they used to be. The right response to the cliff is to grow through it, not to hide beneath it.

Above the cliff the rate is flat, so the arithmetic gets simple: TSh 50,000,000 of turnover means TSh 2,000,000 of tax; TSh 150,000,000 means TSh 6,000,000; TSh 200,000,000 means TSh 8,000,000.

The twelve-month exemption for new businesses

This is the most valuable change in the 2026 Act and the easiest to miss. An individual who obtains a Taxpayer Identification Number for the purpose of commencing a business, and whose turnover is above TSh 4,000,000 but not above TSh 200,000,000, pays nil for the first twelve months from the date the TIN was obtained.

There is a catch written into the Act itself: the exemption is not automatic. You must apply to the Commissioner for it, and the Commissioner grants it where satisfied that you meet the conditions. A new trader who registers, starts trading and says nothing should not assume the relief has been applied to their account.

If you are at this stage, get the sequence right — register the business, obtain the TIN, then apply for the exemption. Our guide to registering a business in Tanzania covers the BRELA and TRA steps in order, and how to start and fund a business covers what comes after that.

Turnover, not profit — and when to opt out

Here is the part that costs low-margin traders real money. Presumptive tax is charged on turnover whether or not you made a profit.

Take a trader with TSh 50,000,000 of turnover reselling goods at a 12% net margin — TSh 6,000,000 of actual profit. Presumptive tax is 4% of turnover: TSh 2,000,000, or a third of the profit.

Now use the right to elect out. Taxed under the normal individual rates, the first TSh 3,240,000 of annual income is not taxed at all and the next slice is taxed at 8%. On TSh 6,000,000 of profit that works out at roughly TSh 220,800 — nearly TSh 1.8 million less than the presumptive charge.

Run the break-even and the picture is clear. On TSh 50,000,000 of turnover, presumptive tax only becomes the cheaper option once your net margin reaches somewhere around 27%. Below that, being taxed on actual profit is cheaper, sometimes dramatically so. High-turnover, thin-margin businesses — general dealers, fuel, wholesale, retail electronics — are exactly the ones the presumptive system treats worst.

Two honest caveats. Electing out means proper accounts and possibly an accountant, so weigh the compliance cost against the saving rather than looking at the tax figure alone. And the election is a formal choice for the year of income: discuss it with the TRA or a tax adviser before you rely on it. You can sanity-check the profit-basis figure with our income tax calculator before you go anywhere near a decision.

What changes as you grow

The presumptive ceiling and the VAT registration threshold now sit at the same number, which makes the growth path unusually clean to plan for. VAT registration becomes mandatory once taxable turnover reaches TSh 200 million in twelve months, or TSh 100 million in any six months — a rule that catches fast-growing businesses earlier than they expect. Professional service providers such as accountants, lawyers and engineers must register regardless of turnover. You have 30 days from becoming liable to apply.

Once registered you charge VAT at 18% and file returns monthly. Our VAT calculator handles the arithmetic of adding and stripping out VAT, which is where most first-time registrants slip up.

Cross the TSh 200 million presumptive ceiling and you leave the simplified system altogether: you are taxed on actual profit and you need accounts to support it. Plan for that transition before it arrives rather than after.

How to register and pay

Register the business with BRELA, where a name reservation is valid for 30 days and registration typically takes two to three working days. Obtain a TIN from the TRA — you need one once turnover passes TSh 1 million. Get a business licence from your local authority under TAMISEMI. If you are starting out, apply for the twelve-month exemption at the same time rather than later.

Keep business money separate from household money. A dedicated business bank account makes turnover provable and record-keeping close to automatic. If a bank will not take you on yet, a SACCOS is a reasonable starting point. And when you do borrow to grow, read how to borrow money safely first — turnover-based tax and turnover-based lending both punish businesses that do not know their own margin.

Rates and bands change with each Finance Act. Confirm the current figures with the TRA before you rely on them for anything that matters.

Frequently asked questions

Is presumptive tax charged on my profit or my sales? On turnover — your gross sales — not profit. This is why a business with thin margins can end up paying a large share of its actual earnings, and why the right to be taxed on profit instead is worth understanding.

My turnover is under TSh 4 million. Do I still need to register? The tax payable is nil, but that is not the same as having no obligations. You still need a TIN once turnover passes TSh 1 million, a business licence from your local authority, and records. Nil tax is an outcome, not an exemption from registering.

Does the twelve-month exemption apply automatically to a new business? No. The Finance Act, 2026 requires you to apply to the Commissioner, who grants it once satisfied that you meet the conditions. Apply — do not assume.

I have a job and a small side business. Can I use presumptive tax? No. The law requires your income to consist exclusively of business income sourced in Tanzania, so employment income alongside a trade takes you out of the regime. See how to make money online and the Tanzania tax guide for how mixed income is treated.

What happens if I do not keep records? For turnover between TSh 4 million and TSh 11 million you pay the higher fixed amount in the left-hand column — up to TSh 100,000 a year more than a trader who does keep records. Separately, record-keeping is a legal duty under the Tax Administration Act and failing it carries penalties of its own.

Do I have to file an annual return? That depends on your circumstances, and the Commissioner can require a return by written notice in any case. Confirm your filing obligation directly with the TRA rather than assuming the presumptive payment is the end of the matter.
