Select Mainland Tanzania or Zanzibar and the legally classified supply. Mainland standard VAT is 18%; the 16% arrangement requires an eligible unregistered recipient, an approved payment channel and TRA conditions. Zanzibar generally uses 15%, with 18% for specified financial, insurance, telecom and digital services. Assessed import or reverse VAT is separated from cash paid to the supplier.

Formula

VAT = assessed net value × applicable rate. Mainland withholding: goods 3% of base; services 6%; qualifying mixed supply from 1 July 2026: 60% of value × 3% + 40% × 6%. Cash cost = total including assessed VAT − approved deferred VAT.

Examples

Mixed taxable supply

Mainland base TZS1000, VAT180. From July2026, statutory allocation gives goods600 and services400; withholding18+24=42; supplier receives1138.

Approved import deferment

Customs base TZS1200, assessed VAT216 and approved deferment216: VAT remains216, current VAT payment0, import value plus current taxes1200.

A PRACTICAL GUIDE

When to use this calculator

Tanzania VAT depends on territory, transaction conditions and the selected payment treatment. This calculator separates mainland and Zanzibar situations and can distinguish mixed supplies, withholding and approved deferment, so the amount assessed and the immediate cash payment can be understood independently.

Information to prepare

Select the territory and date and check whether a conditional electronic-payment rate applies. For mixed supplies, prepare the classification required by the form rather than applying one withholding treatment to the whole invoice. Deferment must be approved and should not be selected solely to reduce the current payment.

How to interpret the result

The tax base is the value to which the selected transaction treatment applies. An inclusive total already contains tax and requires a reverse calculation to recover its net value. These amounts are not interchangeable. Tax charged on an invoice, tax withheld by a customer and eligible input-tax credit describe different obligations. Subtracting two amounts in a cash breakdown does not establish that they have the same legal treatment. Check what each output represents before using it in an invoice or budget.

A practical comparison

When reviewing the result, separate tax assessed from tax withheld or deferred. A deferred amount is not necessarily an exemption from the underlying liability. Employment benefits and PAYE use different bases and belong in the income-tax calculation rather than the invoice VAT model.

Check your calculation step by step

  1. Match the figures to the selected period and use TZS for monetary inputs. If you start with a document in another currency or covering several periods, resolve that difference before entering a combined amount.
  2. Calculate the documented case first. Then change one input at a time to compare scenarios. Keep the original values available so a change in the result can be traced to a particular assumption rather than several simultaneous edits.
  3. Read the component breakdown alongside the formula and examples below. If an official document differs, check the date, base, rounding and omitted concepts before changing a rate or treating the difference as an error.

Frequently asked questions

Does every bank transfer qualify for 16% VAT?

No. The parties and transaction must meet the Commissioner General’s notice and procedural conditions. The buyer must be unregistered and payment must use the prescribed channel. A sale to a withholding agent keeps the standard18%.

Are 15% and 12% the withholding rates?

No. At18% VAT, the agent withholds3% of the net goods value or6% of the service value. The remaining VAT paid to the supplier is15% or12% of that value. From July2026, mixed goods/service value is allocated3:2.

Does deferment mean the VAT is zero?

No. The assessed tax stays visible. Only the amount covered by a valid capital-goods deferment approval is removed from the cash currently payable. Do not combine deferment and withholding without a separate documented assessment.

Do all foreign services attract reverse VAT?

No. Determine liability under the applicable area’s law first. Mainland imported-service scope includes a taxable recipient’s economic activity and a credit-eligibility test; the calculator requires confirmation of that scope and does not presume input credit. A foreign provider already collecting local VAT belongs in invoice mode.
