A few years ago, Ghanaians who wanted to open certain accounts or register a business had to apply for a separate Taxpayer Identification Number. Now, for individuals, the number printed on the Ghana Card does the job.
What changed and why
Since 2021, the Ghana Revenue Authority has used the Ghana Card‘s personal identification number, the PIN that begins with “GHA-“, as the Taxpayer Identification Number for individuals. The change was part of wider efforts to link public services to the national identity system. Using one number reduces duplication. Before, a person could have several numbers across different institutions. Linking the tax number to the Ghana Card makes it easier to identify taxpayers and harder to hide income.
Where you need it
The number is used for many transactions: opening bank accounts, registering businesses, land and property transactions, some government payments, import clearing and filing tax returns. The change applies to individuals. Companies and other organisations have their own TINs. Business owners should check the requirements with the GRA and the Office of the Registrar of Companies.
If you already had an old TIN before the change, it should be linked to your Ghana Card. If an institution rejects your Ghana Card number as a TIN, contact the GRA to check that the link is in place.
Validity, privacy and filing
Because the Ghana Card is now central to banking, SIM registration and taxes, keep it safe and valid. If it is lost or damaged, contact the National Identification Authority for a replacement. Linking so many services to one number raises questions about data protection. Ghana has a Data Protection Act and a Data Protection Commission. Be careful about sharing photos of your card on social media or with unknown people.
Having a TIN does not by itself mean you owe tax. Salaried workers usually pay through their employers. Self-employed people and landlords should learn their obligations and file on time.
For Ghanaians abroad
Ghanaians living outside the country who need a TIN for property, banking or business at home can register for the Ghana Card at designated centres abroad or during visits. Checking the requirements before travelling saves time, since many transactions now stall without the PIN. For most Ghanaians, the change is small: one fewer form to fill. But it shows how the Ghana Card has become the key to most official doors, and why losing it now causes far more trouble than it once did.
