This is the general edition of this guide for Zambia. It explains how the TPIN, VAT and annual filing work and names Zambia Revenue Authority (ZRA) as the place to confirm thresholds and dates. Country-specific figures are added as each edition is reviewed.
What the TPIN is
The TPIN is the number Zambia Revenue Authority (ZRA) assigns to a taxpayer in Zambia. It follows you across every tax you deal with: VAT, income tax and withholding. Businesses that pay you will ask for it before they release payment, because they report their suppliers to Zambia Revenue Authority (ZRA) 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 Zambia Revenue Authority (ZRA). Choose the taxes you will be liable for; do not add VAT unless you must or want to register for it.
Download or collect the registration certificate. It shows your TPIN; keep the PDF, because clients will ask for it.
Add the TPIN to your invoice template and letterhead.
How to find or check a TPIN
Your own number is on the registration certificate and on every letter or notice from Zambia Revenue Authority (ZRA). 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 Zambia invoice generator has a TPIN field in both blocks.
Questions people ask
Does it cost anything to get a TPIN?
Registration with Zambia Revenue Authority (ZRA) 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 TPIN?
You can write the document, but many clients will not pay an invoice that has no TPIN, and you cannot charge VAT without being registered. Register first; it is usually quick.
Is the TPIN the same as VAT registration?
Not necessarily. The TPIN identifies you as a taxpayer; VAT 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 VAT 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.
