Filing with the NRS

A prepared return is not a filed return. This part covers the authority's side of the work: registration, deadlines, portals, assessments, disputes, payments and the paper that proves it all happened. It is written against the Nigeria Tax Administration Act 2025, and it is the part of the course that dates fastest, so every process here carries a simple professional rule: verify the current step against official NRS guidance before you rely on it.

Everything starts with the Tax ID. An individual registers once, with identity anchored to their NIN, through their tax authority; a company incorporated at the CAC is issued its Tax ID with registration, while older companies register with the NRS directly. One taxpayer, one ID, used across every tax. An agent checks the TIN at intake, because a client without one cannot file, and Part 3 already taught you to prepare the return in parallel while registration completes.

Then the destinations, which Part 1 made structural: a personal return goes to the state where the client is resident; company income tax, the Development Levy and VAT go to the NRS. The calendar hangs off five dates you should be able to recite while frying plantain. Individuals file their annual return of all income by 31 March following the year. Employers remit PAYE by the 10th of each following month and file their annual return of employees by 31 January. VAT returns land by the 21st monthly. Companies file within six months of their own financial year end, with a first-return window tied to incorporation for brand-new companies. Miss a date and penalties accrue with time, plus interest on unpaid tax, which is why Part 8 builds deadline management across a whole client book.

Nigeria runs self-assessment: the taxpayer computes, files and pays, and the authority accepts or queries. That is where the division of labour on HopperTax becomes clear. Your professional responsibility runs from intake to a complete, checked, client-approved package; filing is the platform's job, on every return, so the same standard applies every time and you never hold a client's portal credentials. The acknowledgment comes back into the client's vault, because an unacknowledged filing is an argument waiting to happen. When the authority disagrees, or when no return was filed at all, it can raise an additional or best-of-judgment assessment. The response discipline is the objection: written, within 30 days, stating the grounds. An unresolved objection escalates to the Tax Appeal Tribunal and from there to the courts, while complaints about the authority's conduct, rather than the amount, belong with the Tax Ombud.

Money and evidence close the loop. Payments go through approved channels against the assessment or payment reference, so the money lands against the right liability, and every payment produces a receipt you keep. Three consecutive years of clean filings support a Tax Clearance Certificate, the document Nigerian business life actually runs on: contracts, licences, many banking processes. Overpayments and unclaimed withholding credits support refund claims, or can be set off against future liabilities, and patience plus paperwork is the honest description of that process.

The part ends with professional conduct before the authority: act under proper written authorization, never impersonate the client, and keep the line between preparation, which is yours, and filing, which is the platform's. Ten questions, then Part 7 takes on the border-crossing cases.
