Someone applying for a building approval or a trade licence does not expect to be asked for a tax document. It comes as a surprise to a lot of people, right up until they read the actual law.
The list of things a tax clearance certificate is tied to is wider than tenders and bank loans.
The law behind this list
A tax clearance certificate is required for certificates of occupancy, building plan approvals, government contracts, firearms licences, import and export licences, and trade licences. Property paperwork and personal or trade licences sit on that list by name, not as an informal add-on some offices invented.
The law places the duty on the government side too. A ministry, department or agency handling one of these matters must ask for the certificate. It is a condition of dealing with you, not an optional extra.
Certificates of occupancy and building plan approval
Land and building work is one of the clearest examples. A certificate of occupancy and a building plan approval both sit inside the statutory list. That is why some land offices now build a TCC check into their own process.
If you are part-way through either of these and have not been asked yet, check anyway. Do not assume the rule skips your case.
Firearms, import-export and trade licences
The licence side of the list covers firearms licences, import and export licences, and trade licences. These sit next to the property matters above, under the same rule, even though they look unrelated at first glance.
A trade licence renewal is the one most small business owners actually meet. It is easy to assume a trade licence office only cares about local paperwork. Then a TCC request shows up in the requirements.
A state example: Oyo enforcing the rule directly
This is not just a quiet line in a federal act. State bodies must not accept a trade or professional licence unless the holder has a valid TCC — a rule Oyo's revenue service announced under the state's own law, not the federal Act. That is one clear, documented case of a government office applying the same idea to real transactions, not leaving it on paper.
Whether or not your own state has publicised a rule like Oyo's, the federal law already applies nationally. Assume a government office can ask for your TCC on these matters wherever you are, and do not assume the requirement is limited to states that have said so publicly.
What to do if an office asks for a TCC you did not expect
Treat the request as routine, not as a sign something is wrong with your application. Start gathering your Tax ID, your returns for the last three years and your accounts as soon as you know a certificate is needed, since these underpin every version of a TCC application, whatever triggered the request.
Our checklist of documents for a TCC application covers exactly what to prepare. Once you are ready, the tax clearance certificate page is where a vetted partner firm can take it from there, and our tax hub on the Nigeria Revenue Service (NRS), formerly FIRS, has more on the Tax ID that sits behind every application.
