If you sell on Instagram, TikTok, Facebook or WhatsApp, you have probably heard that TRA now wants online sellers to show their tax number on their pages. Many business owners are worried and confused. This guide explains online business tax in Tanzania in simple words: what changed in 2026, what you must do, and how to stay on the right side of TRA without stress.
This article is general information, not tax advice. Tax rules change, so confirm the details for your business with TRA or a registered tax consultant.
Do online sellers pay tax in Tanzania?
Yes. To TRA, selling online is business like any other. If you sell goods or services to make a profit, the same tax rules apply whether your customers find you in a shop in Kariakoo or on your Instagram page. Online sellers are expected to register with TRA and get a Taxpayer Identification Number (TIN).
The good news is that small businesses do not pay the same tax as big companies. Most small online sellers fall under the presumptive tax system, which is simpler and lower.
What changed in 2026: the TIN display rule
From 1 July 2026, under amended tax administration regulations, anyone doing business on social media in Tanzania must display their TIN, TIN certificate or tax clearance certificate on their business accounts.
Here is what TRA has explained about the rule, as reported by Daily News:
- It applies to businesses operating in Tanzania, whether you work from home or from a shop.
- Non-resident sellers are excluded, because they are not required to have a Tanzanian TIN.
- You only show what the regulation asks for. TRA says displaying your business TIN or tax clearance certificate does not, by itself, break data protection rules.
- There is no special penalty in the new regulation. But not complying can fall under the general offence section of the Tax Administration Act, and TRA can ask you to regularise your position.
- TRA is starting with education and voluntary compliance, so this is the right time to get registered calmly instead of waiting.
How to display your TIN on social media
Keep it simple and professional:
- Instagram and TikTok: add a short line to your bio, such as “TIN: 123-456-789”.
- Facebook page: add it to the About or Intro section.
- WhatsApp Business: add it to your business profile description.
Show your business TIN only. Never post your passwords, ID card or other personal documents.
Step 1: Get your TIN
Registering for a TIN is the first step for every online seller. Under the Finance Act 2026, a person starting a business should apply for a TIN within 15 days of starting. You can apply through TRA’s online services on the TRA website, or visit a TRA office near you. Have your NIDA number ready.
If you also want a registered business name, you register it separately with BRELA.
Step 2: Know which tax you pay
Presumptive tax for small businesses
If your yearly sales (turnover) are small, you pay presumptive tax: a simple tax based on how much you sell, not a long calculation of profit. Under the Finance Act 2026:
- The presumptive system now covers businesses with turnover of up to TZS 200 million a year. Before, the limit was TZS 100 million.
- For turnover above TZS 11 million and up to TZS 200 million, the rate is 4% of turnover.
- Very small turnover is taxed with lower fixed amounts, and the smallest businesses pay nothing. TRA publishes the current bands.
Some services, such as professional, technical, management, construction and training services, cannot use presumptive tax and must file normal tax returns.
A one-year tax holiday for new businesses
The Finance Act 2026 also introduced a one-year income tax holiday for new individual businesses under the presumptive system, with turnover between TZS 4 million and TZS 200 million. The holiday starts from the date you get your TIN, and it needs approval from the TRA Commissioner General, with conditions. If you are starting now, ask TRA whether you qualify. It is another reason to register early.
VAT for bigger online businesses
If your turnover goes above TZS 200 million a year, you must also register for VAT. Most small online sellers are far below this level.
Content creators and influencers
If you earn as a content creator, note that payments to resident digital content creators have 5% withholding tax under the Finance Act 2024, according to TRA. If you earn this way, read how influencers make money in Tanzania too.
Step 3: Keep simple records
Even small sellers should write down every sale and expense. A notebook, a spreadsheet or the record feature in your mobile money statements is enough to start. Good records:
- show TRA your real turnover, so you pay the correct amount
- help you see which products actually make profit
- make it easier to get loans and work with bigger clients
If your turnover is above TZS 11 million a year, you are expected to keep proper records and use an Electronic Fiscal Device (EFD) for receipts.
Why registering is good for your business
Many sellers see tax only as a cost. But a visible TIN can work for you:
- Customers trust you more. A registered business looks serious, and that helps when people are afraid of online scams.
- Bigger clients can buy from you. Companies and offices often need receipts and a TIN before they pay a supplier.
- You can grow without fear. When your business grows, you won’t have to hide it.

Final word
The new rules are not meant to stop online businesses. They bring online sellers into the same system as shops. Register, display your TIN, keep records, and you can focus on what matters: selling more.
