Anyone running a business through social media in Tanzania is now legally required to display their tax details on their profile, where anyone can see them.

The requirement comes from the Tax Administration (General) (Amendment) Regulations, 2026, published as Government Notice No. 158G on 30 June 2026 and signed by Minister for Finance Khamis Mussa Omar in Dodoma. The regulations took effect on 1 July 2026. They amend regulation 58 of the Tax Administration (General) Regulations, 2016, made under Tanzania’s Tax Administration Act.

The new sub-regulation says a person conducting business on social media shall, “for easy of inspection and enforcement”, display their certificate, Tax Identification Number or Tax Clearance Certificate on their social media profile or account “in a manner that is easily seen”. That is the gazette’s own wording, rough grammar included. The whole amendment runs to a single paragraph.

What a TIN is, and where this rule comes from

A Tax Identification Number (TIN) is the number the Tanzania Revenue Authority (TRA) issues to every taxpayer. It is the direct equivalent of a KRA PIN in Kenya. Individuals get a 10-digit number, registered businesses get a 9-digit one, and anyone conducting business in Tanzania must have one, from limited companies down to sole proprietors. A Tax Clearance Certificate is a separate TRA document confirming that a taxpayer has no outstanding tax debts.

The display idea itself is not new. Regulation 58 of the 2016 regulations already required every person issued with a TIN certificate to display it “at a conspicuous place to be seen by every person”, meaning the wall of the shop or office. Kenyan businesses do something similar with county permits pinned up behind the counter. What the amendment does is treat a social media account as business premises. The framed certificate on the wall now has a digital twin on the profile page.

Who is covered, and what is missing

The amendment applies to “a person conducting business on social media”. It does not define that phrase, name any platforms, or set a turnover threshold. Read plainly, an Instagram thrift store, a WhatsApp status seller, a TikTok live auctioneer and a large retailer’s Facebook page are all covered equally. The amendment also does not state a penalty for non-compliance, and it does not say how TRA will inspect accounts.

The stated purpose is inspection and enforcement. A tax officer scrolling through seller accounts can now check compliance from a screen, without visiting anyone. Tanzania has been widening its digital tax net for a while. In 2022 it required non-resident electronic service providers earning from Tanzanians to register for a TIN and VAT number. This amendment reaches the other direction, at the small domestic sellers who trade entirely inside apps.

The part that sits uncomfortably

The rule lands in a country with a difficult recent history between the state and social media. We covered Tanzania blocking X in May 2025, during a period when Kenyan activist Boniface Mwangi and Ugandan lawyer Agather Atuhaire were detained there. We also covered the nationwide internet blackout that started on election day, 29 October 2025, and ran to 3 November. UN human rights experts condemned that blackout in December 2025, alongside allegations of extrajudicial killings and enforced disappearances after the vote.

A TIN certificate carries the holder’s registered name, and for businesses it is tied to a registered premises address. Displaying it publicly ends anonymous and semi-anonymous selling on Tanzanian social media. It also hands that identity to everyone who opens the profile, tax officers and otherwise. In a country where Access Now and the #KeepItOn coalition have repeatedly documented the state using connectivity and platform access as pressure tools, a legal duty to attach your legal identity to your account is a real cost, separate from the tax question. Scammers and impersonators also get a new artefact to fake: a screenshot of a TIN certificate on a profile proves very little to a buyer who cannot verify the number.

Kenya has nothing equivalent. KRA has gone after online business through other routes, including the 2024 proposal for a 15% excise duty on social media and internet services and the eTIMS push we have written about, but no Kenyan rule requires a KRA PIN on a social media profile.

The practical takeaway is simple. If you sell anything through a social media account in Tanzania, the law has expected your TIN or tax clearance certificate to be visible on that profile since 1 July 2026. What to watch is whether TRA publishes guidance on format and penalties, and whether enforcement actually reaches the WhatsApp seller or stops at the accounts big enough to find.
