Visa: what the sources say

Option Duration Good to know
Electronic tourist visa 90 days, single entry About USD 50 according to one source; see visa and entry fees
"Remote work visa" Claimed by some sites Fees and conditions contradict between sources: not confirmed
Class C residence permit 3 to 6 months of procedure About USD 500 to 800 according to one source; not designed for nomads

Tax: under 183 days you are generally not a tax resident, and only Tanzanian-sourced income is taxed (according to a cost-of-living site). Take professional advice.

Wifi, coworking and connectivity

Sources name coworking spaces such as The Zanzibar Coworking and The Bureau, around USD 150 a month for a desk with basic internet. The average speed quoted is about 20 Mbps, with outages. A backup eSIM avoids being stuck: see Tanzania eSIM. For a long-stay villa, some install Starlink.

Where to stay to work

Choose an area with stable power and shops: Stone Town for city life, see where to stay in Zanzibar. For heat and tides, see tides and swimming.

Insurance

International health insurance is essential on a long stay: see travel insurance for Zanzibar.
