This is the general edition of this guide for Somalia. It explains how the TIN, Sales tax and annual filing work and names Inland Revenue Department, Ministry of Finance as the place to confirm thresholds and dates. Country-specific figures are added as each edition is reviewed.
What the TIN is
The TIN is the number Inland Revenue Department, Ministry of Finance assigns to a taxpayer in Somalia. It follows you across every tax you deal with: Sales tax, income tax and withholding. Businesses that pay you will ask for it before they release payment, because they report their suppliers to Inland Revenue Department, Ministry of Finance by this number.
Who needs one
Anyone who earns taxable income, runs a business, employs staff or wants to be paid by a company that must report its suppliers. In practice, if you invoice, you need one.
How to register, step by step
Gather your identity document and, for a business, the registration certificate and the owners' or directors' details.
Register with Inland Revenue Department, Ministry of Finance. Choose the taxes you will be liable for; do not add Sales tax unless you must or want to register for it.
Download or collect the registration certificate. It shows your TIN; keep the PDF, because clients will ask for it.
Add the TIN to your invoice template and letterhead.
How to find or check a TIN
Your own number is on the registration certificate and on every letter or notice from Inland Revenue Department, Ministry of Finance. Most authorities now offer an online lookup to confirm a supplier's number and registered name before you pay them; use it for any new supplier.
Where it goes on your paperwork
In the invoice header next to your business name, and in the client block when the client is a registered business. Quotations and purchase orders carry it too, so the client's accounts team can match documents. The Somalia invoice generator has a TIN field in both blocks.
Questions people ask
Does it cost anything to get a TIN?
Registration with Inland Revenue Department, Ministry of Finance is normally free. Agents charge for filling in the same form; pay one only if you want the time saved.
Can I invoice without a TIN?
You can write the document, but many clients will not pay an invoice that has no TIN, and you cannot charge Sales tax without being registered. Register first; it is usually quick.
Is the TIN the same as Sales tax registration?
Not necessarily. The TIN identifies you as a taxpayer; Sales tax registration is a separate status you take on when turnover passes the threshold or you opt in. Some countries use one number for both, others issue a separate Sales tax number.
How long does registration take?
Online registrations are often instant or take a few days; applications that need a visit or document checks take longer. Start before you need to send your first invoice.
