FG Issues Transition Guidelines for Implementation of Tax Acts 2025

The Federal Government has released the General Transition Guidelines for the implementation of the Tax Acts 2025.

The guidelines explain how Nigeria will move from the old tax laws to the new tax system, which took effect on January 1, 2026.

They were issued by the Federal Ministry of Finance under Section 144 of the Nigeria Tax Administration Act 2025 and Section 200 of the Nigeria Tax Act 2025.

The guidelines were signed by the Honourable Minister of Finance and Coordinating Minister of the Economy, Mr Taiwo Oyedele.

They are meant to guide taxpayers, businesses, investors, tax practitioners and tax authorities during the changeover to the new system.

The new tax framework is built around four major laws. They are the Nigeria Revenue Service Establishment Act, the Nigeria Tax Act, the Nigeria Tax Administration Act and the Joint Revenue Board Establishment Act.

For businesses and investors, the biggest message is certainty.

The guidelines make it clear that the new tax laws will not be applied backward. This means transactions, supplies or asset sales completed before January 1, 2026, will not be reassessed under the new laws.

What the transition guidelines mean

The transition guidelines explain how tax matters should be handled as Nigeria moves from the old tax laws to the new system.

Tax liabilities, assessments, audits, investigations, disputes and enforcement actions linked to periods before January 1, 2026, will still be treated under the old tax laws.

In simple terms, the new tax laws will not affect completed transactions or tax obligations from earlier periods.

This is important for taxpayers. It reduces confusion and helps companies prepare their filings, audits and financial records based on the law that applied at the time.

What taxpayers should know

Tax returns for accounting periods ending before January 1, 2026, will be filed under the old tax laws.

Tax returns for accounting periods ending on or after January 1, 2026, will be handled under the new tax framework.

This gives businesses, accountants and tax advisers a clear line between the old system and the new system.

The guidelines also cover income taxes, transaction taxes, development levies, tax incentives, exemptions, record keeping duties and transactions that fall between the old and new tax regimes.

For companies with transactions that cut across both periods, the guidelines will help explain which rules apply.

Existing tax incentives will remain valid

The Federal Government said existing tax incentives and exemptions granted under the old laws will remain valid until their expiration dates.

This means businesses and investors that already received tax incentives will not lose them just because a new tax regime has started.

However, new applications and pending requests will be considered under the Tax Acts 2025.

This is important for investor confidence. It protects existing commitments while allowing new applications to follow the new rules.

Development levies are being consolidated

One major change under the new tax regime is the treatment of development levies.

Levies such as TETFUND, NASENI and NITDA will be replaced by a consolidated development levy for accounting periods ending after the commencement date.

This should make compliance easier for companies.

Before now, many companies had to deal with different levy obligations. Under the new system, those levies will be brought under one structure.

For corporate finance teams, this matters because it affects tax planning, company accounts and financial provisions for the 2026 year of assessment.

Small businesses may get more relief

The guidelines also reflect wider relief for small businesses.

The small company threshold has increased from ₦25 million turnover to ₦100 million turnover, with an additional ₦250 million asset test.

This means more small businesses may qualify for relief under the new tax framework.

For micro, small and medium-sized businesses, this could reduce tax pressure.

It could also support business survival at a time when many companies are facing high costs, inflation and weak consumer spending.

Unclear tax rules will favour taxpayers

Another important part of the guidelines is how unclear provisions will be treated.

Where the Tax Acts conflict or create confusion, the guidelines say the matter should be resolved in favour of the taxpayer.

This is important because new tax laws often create interpretation problems at the early stage.

By focusing on clarity, fairness and certainty, the government is trying to reduce disputes between taxpayers and revenue authorities.

What the data is saying

The guidelines show that the government wants a smooth move into the new tax system.

Here are the key points:

Tax matters before January 1, 2026, remain under the old laws.

Tax matters from January 1, 2026, will be handled under the new framework.

Existing incentives remain valid until they expire.

New and pending incentive applications will be treated under the Tax Acts 2025.

The small company threshold has been expanded.

Several development levies are being merged into one levy.

Unclear parts of the law should be resolved in favour of the taxpayer.

What you should know

This is not just a technical tax update.

It affects businesses, investors, accountants, tax advisers and government revenue agencies.

For businesses, the guidelines explain how to prepare tax returns, manage audits and treat transactions that fall between the old and new laws.

For investors, the guidelines reduce the risk of sudden backward tax treatment.

For tax authorities, the guidelines create a common approach that should support fair enforcement across federal, state and local levels.

For taxpayers, the main message is simple. The new tax laws are not meant to be applied backward.

Expert view

Tax and fiscal policy experts are likely to see the transition guidelines as an important step in making Nigeria’s tax reform easier to implement.

A new tax law can create confusion.

Taxpayers may not know how to handle old obligations, pending disputes, existing incentives and ongoing filings.

Revenue agencies may also apply the rules differently if there is no clear guide.

These guidelines reduce that risk by setting clear rules for the transition.

For businesses, the biggest benefit is certainty. Companies can now separate old tax matters from new tax obligations and plan their compliance with more confidence.

However, implementation will be the real test.

If revenue agencies apply the guidelines differently, businesses may still face confusion.

The government will need strong coordination among the Nigeria Revenue Service, State Internal Revenue Services, the FCT Internal Revenue Service and Local Government Revenue Committees.

The expanded small company threshold could also support small businesses. But the process must be simple, transparent and easy to access.

Why this matters for Nigeria’s economy

Nigeria is trying to increase revenue while also improving the business environment.

The transition guidelines are part of that wider reform effort.

If implemented properly, they can improve tax compliance, reduce disputes and support investor confidence.

They can also make the tax system easier to understand.

But poor implementation could create more confusion for businesses and taxpayers.

The government must ensure that tax officers, companies, accountants and small business owners understand the new rules clearly.

A modern tax system should not only collect revenue. It should also be predictable, fair and easy to comply with.
