A business in Tanzania may operate from fixed premises, a home, a market, a street location or another setting. Informal micro and small businesses can reach customers without complete formal registration, but they generally have less formal protection and weaker access to finance, tenders and other institutional opportunities. Formalisation gives the business a recognised identity and can support contracts, market access and financing. On Mainland Tanzania, an individual or partnership of up to 20 people can register a Business Name with BRELA. A Business Name records the business identity but does not create a separate company legal personality. A company registered with BRELA can be private, public or foreign, including a foreign company branch. Company registration creates a separate legal personality and brings additional duties. A foreign individual may need a passport or NIDA identification and a TIN, while foreign participation can also require a Residence Permit Class A or the relevant company or branch structure. The usual Mainland sequence is to define the activity and premises, apply through BRELA's ORS or BOS system, obtain a TRA Taxpayer Identification Number, secure sector permits where required and obtain a Business Licence. Class A licences are handled through BRELA and Class B licences through the relevant district, town, municipal or city council. Since 2026, new, branch and renewal licence applications are primarily handled through BOS, while ongoing TNBP cases continue through that system. Licence requirements and fees depend on the activity, location and sector. Zanzibar follows a separate pathway through BPRA for Business Name or company registration, followed by ZRA tax registration and a Zanzibar Taxpayer Identification Number, known as ZTN, then BLRA or the responsible licensing authority. A Zanzibar Business Name can cover an individual or a partnership of two to 20 people. The applicant generally needs the relevant Tanzania or Zanzibar identity document, a personal mobile number, email address and business or residential address. ZRA registration is generally required within 15 days of starting business. ZIPA's One-Stop service and an Investment Certificate apply to qualifying investment projects, not to every startup. Formal businesses need a valid Business Licence before operating, together with any sector-specific approvals. They may also need to issue receipts through an EFD or the applicable ZRA system, file tax returns and obtain tax clearance. Companies file an Annual Return on each anniversary, maintain accounts appropriate to their legal form, submit Beneficial Ownership information and update changes to directors, address or ownership. A registered Business Name also requires annual maintenance and updated registered particulars. BRELA and BPRA provide procedures for registering trademarks, patents and other industrial property. Indicative Mainland Business Name charges include TZS 15,000 for an application, TZS 5,000 for annual maintenance, TZS 10,000 for a cessation notice and TZS 15,000 for a change. The stated registration time is about eight working hours. Company incorporation fees vary with share capital and are approximately TZS 95,000 to TZS 440,000, with additional constitution, filing and stamp costs. Annual Return fees are TZS 22,000, with a late charge of TZS 2,500 per month or part of a month. Zanzibar publishes different charges, including TZS 15,000 for an individual Business Name, TZS 50,000 for a partnership, TZS 20,000 for a change and TZS 20,000 for closure. Its stated certificate time can be up to 24 working hours, while BLRA procedures and timing should be confirmed for the specific case because published minimum and maximum times conflict. Premises, sector permits, tax, inspections and licence fees create additional costs. SIDO supports startups, existing small and medium-sized businesses and informal-to-formal transitions through business-skills training, consultancy, incubation, premises, technical advice, technology transfer, packaging, market links and financial or credit-guarantee connections. Programme availability and fees vary; one example course lasts two weeks and costs TZS 250,000. Rural value-chain support can be limited to particular regions. Day-to-day operation also requires separate bookkeeping, cash-flow control, market management and compliance tracking. A business does not close legally merely because it stops trading. A Mainland Business Name can submit an online cessation notice, while a company follows statutory strike-off or winding-up and liquidation procedures. Zanzibar has BPRA closure and annual-return procedures. Tax registrations, licences, debts, contracts, records and intellectual property need separate treatment when the activity ends.
Business in Tanzania
Entrepreneurship in Tanzania can take the form of an informal activity, a registered Business Name, or a company. Mainland Tanzania and Zanzibar use separate registration, tax and licensing administrations. Formal operation usually requires registration, a tax number, any sector permits and a valid Business Licence.
Tip
Choose the legal form and administration according to where the business will operate, who owns it and whether it needs a separate legal identity. Treat registration, tax, sector permits, licensing and ongoing filings as one compliance plan, and do not assume that Mainland Tanzania registration covers Zanzibar or that informal trading provides the same protection and access.
