Nobody likes paying more tax than they legally have to.

That is why businesses plan around taxes. They choose how to structure transactions, when to make certain investments and which incentives or reliefs they are entitled to use.

There is nothing automatically wrong with that.

The problem starts when the tax benefit becomes the real reason for the arrangement.

Nigeria’s new tax framework is drawing more attention to that line.

Tax planning is not the same as tax avoidance

A business choosing a tax efficient option does not automatically mean it is avoiding tax.

The bigger question is why the arrangement exists and whether it has a genuine commercial purpose.

The Nigeria Tax Administration Act 2025 gives the tax authority powers to challenge certain arrangements that are artificial, fictitious or designed primarily to obtain a tax advantage in ways that go against the purpose of the law. 

That could include arrangements that exist largely on paper, lack commercial substance or use the tax law in a way it was not intended to be used.

And now, some tax planning arrangements must be disclosed

The NTAA also introduces a mandatory disclosure regime.

Where a person enters into, or intends to enter into, a disclosable transaction or agreement whose principal purpose is to obtain a tax advantage, information about that arrangement may have to be provided to the relevant tax authority without waiting for a request. 

The definition of tax advantage is broad.

It includes reducing or avoiding a tax liability, obtaining a tax relief or repayment, delaying a tax payment, or avoiding an obligation to deduct or account for tax.

But this does not mean every transaction that saves tax must be reported.

The key phrase is “principal purpose.”

If a business makes a genuine commercial decision and that decision happens to produce a tax benefit, that is different from creating an arrangement mainly because it produces a tax benefit.

So where does Nigeria draw the line?

There is no single sentence that can answer every situation.

The new framework instead gives the tax authority tools to look at the substance and purpose of arrangements.

That means businesses need to think beyond:

“Can I legally structure this transaction this way?”

They also need to ask:

“Why am I structuring it this way?”

And, perhaps more importantly:

“Can I show the commercial reason if someone asks?”

That last question is where documentation becomes important.

Contracts, invoices, receipts, transaction records and supporting documents can help establish what actually happened and why.

The NTAA separately requires taxpayers to maintain books and records containing enough information to determine their tax liability. 

The tax system is becoming more interested in the story behind the numbers

Nigeria’s tax reforms are not only changing tax rates and thresholds.

They are also giving tax authorities more tools to understand transactions, identify potential avoidance and require information about certain tax planning arrangements.

For businesses, that means tax compliance is becoming less about keeping figures for filing season and more about having a clear record of how those figures came about.

Tax planning is legal. Tax avoidance is where the rules start to draw the line. Knowing where that line is, and keeping the records to support your decisions, is becoming increasingly important.
