Free Tanzania calculators for salary, tax and mobile money

Calculator is a working reference for money in Tanzania, published by Delta Tech Solutions in Dar es Salaam. The tools work in shillings and follow the rules that apply here: the TRA PAYE bands, NSSF and PSSSF pension contributions, the 18% VAT rate, HESLB student-loan deductions, the SDL and WCF levies an employer pays on top of wages, mobile-money tariffs, service levy and presumptive tax, property transfer duty and vehicle registration fees.

Every tool prints its formula, states the assumptions it makes and names the cases where the answer does not apply; the ones that depend on a published rate or tariff cite where that figure came from and when it was last checked. Figures are maintained by David M, and each page carries the date of the next scheduled check.

Nothing in that register is undated. Every figure carries the date it was last read from the authority that publishes it — by the weekly automated check where the source is machine-readable, and by a person where it is not — and a figure that loses its source goes back to being listed as undated rather than keeping a date nobody earned.

That date matters. Tax bands are revised, tariffs change and exchange rates move daily, so a figure without a date is only a guess. Every figure, its source, and when it was last checked.

One thing this site does not claim: no external tax, accounting, legal or medical professional has reviewed these pages. The calculators apply published rules to the numbers you enter. Where the amount matters, confirm it with the authority that sets the rate — the links on each page, and the figure register, are there for exactly that.
