Asking the NRS for an advance ruling
When a Nigerian firm should seek an NRS advance ruling on a client's transaction, what the application involves and how to keep the file.
By Achekam · · 5 min read · For Accountants & audit firms in Nigeria
A manufacturing client plans to restructure: a new holding company, assets moved between group members, a management fee charged across the group. The directors want to know the tax consequences before they sign anything. The firm's tax partner has a view, but the Nigeria Tax Act has only been in force since 1 January 2026, few of its provisions have been tested, and getting the answer wrong could cost the client far more than the fee for the advice.
This is the situation an advance ruling exists for. Instead of relying on the firm's interpretation alone, the client can ask the Nigeria Revenue Service how it will apply the law to the specific transaction, before the transaction happens.
A binding answer on one transaction
The NRS explains in its FAQ that an advance ruling is a binding decision by the tax authority on how tax law applies to a specific transaction. It is applied for in the prescribed form, and the NRS says a response is due within 21 days. The FAQ places this under the Nigeria Tax Administration Act, 2025.
Two words in that description shape when a ruling is worth seeking. "Binding" is what makes it valuable: the client gains certainty about the authority's position. "Specific" is what limits it: a ruling addresses the transaction described in the application, so a vague or general question will not produce a useful answer, and a transaction that changes after the ruling may fall outside it.
The NRS frequently asked questions page sets out the advance ruling definition and the response time, along with what the change from FIRS to the NRS means for taxpayers.
When a ruling is worth the effort
Not every uncertain point justifies an application. A firm should consider recommending one where several of these are true:
- The amount at stake is significant relative to the client's size.
- The law is new or unclear on the point, and the firm's view is a reasonable reading rather than a settled one.
- The transaction is still in the future, so its terms can be adjusted if the ruling is unfavourable.
- Anti-avoidance rules could be engaged. The NRS describes the Nigeria Tax Act as including general anti-avoidance and substance-over-form rules, with powers to disregard artificial or fictitious arrangements. A transaction with a strong tax motive is exactly the kind where the authority's view is worth having first.
- The client wants certainty for its board, lenders or investors.
Where the transaction has already happened, or the point is routine, a well-documented file position is usually the better route. How to build that position is explained in documenting client tax positions under the anti-avoidance rules.
The prescribed form, the guidelines and the timetable
The application is made in the prescribed form, so the first step is to obtain the current version. The NRS Tax Guides page publishes its current guidelines and information circulars, and lists Advance Ruling Guidelines among them; the file name of that document carries the date 31-08-26. Read the guidelines before drafting, because they, rather than general practice, set out what the NRS expects an application to contain.
The 21-day response time is the NRS's stated figure at the time of writing. Build it into the client's timetable, but plan for the possibility of questions from the NRS, and do not let the client commit to the transaction on the assumption that a ruling will arrive on a particular date.
Rulings that began under FIRS
Some clients will have applications that started before the rebranding. The NRS says ongoing audits, advance rulings, objections, appeals and disputes started under FIRS continue under the NRS without restart or revalidation. A pending application does not need to be resubmitted. It does, however, need a check: confirm with the NRS that the application is on its records, and note any correspondence received since the change. The wider position on matters in progress is covered in client matters begun under FIRS.
Gathering the facts and recording the firm's view
An application stands or falls on the accuracy of the facts it describes. A ruling obtained on an incomplete description may not protect the client at all.
In Achekam, staff can raise requests to the client for documents, answers and confirmations and track them in one RFI console, whichever screen the request was raised from. For an advance ruling, that typically means requesting the draft agreements, the group structure chart, board minutes approving the transaction in principle, and a written confirmation from management that the description of the transaction is complete. Each request and the client's response stay together, so the file shows what the client confirmed and when.
The firm's own analysis belongs in a technical consultation. Staff can take a consultation on an engagement from question to conclusion and closure, and if partners disagree about the treatment, record the difference of opinion with each party's position, the escalation and the resolution. The consultation shows why the firm recommended seeking a ruling and what view it took of the law.
The application itself, the NRS's acknowledgement, any questions it raises and the final ruling go into the client's folder in the Document Centre, where files are versioned, tagged and searchable. Tag them so that anyone preparing a later return can find the ruling quickly.
Using the ruling afterwards
A ruling is only useful if it is applied. Three habits help:
- Compare the transaction as executed with the transaction as described. If the terms changed, decide whether the ruling still applies, and record that decision.
- Reference the ruling in the working papers for every return it affects, so the reviewer sees why the treatment was chosen.
- Revisit it when the law changes. A ruling given on the law as it stood may need to be reconsidered after an amendment.
Look at the client transactions currently being planned across the firm. For any with a significant tax consequence and an unsettled point of law, open a technical consultation now, and decide with the partner whether an advance ruling application should be made before the client commits.
