Tax Filing in Nigeria (2026): What Has Changed and What Businesses Must Prepare For

Why Nigeria Introduced Tax Reforms

Nigeria has historically recorded a relatively low tax-to-GDP ratio compared to many other economies. This has limited government revenue and increased reliance on borrowing to fund infrastructure and public services.

To address this challenge, the Nigerian government launched a comprehensive tax reform programme designed to:

Simplify the country’s tax system
Improve tax compliance and transparency
Reduce overlapping taxes and levies
Expand the tax base
Encourage economic growth and investment

These reforms were developed by the Presidential Committee on Fiscal Policy and Tax Reforms, which recommended significant updates to Nigeria’s tax laws and administrative systems.

The result is a new tax framework that takes effect from 2026, introducing important changes for both individuals and businesses.

The New Tax Laws Introduced in Nigeria

Nigeria’s updated tax framework is built around four major legislative reforms designed to modernize the country’s tax system.

Nigeria Tax Act (NTA)

The Nigeria Tax Act consolidates several existing tax laws into a unified framework. It defines taxable income, tax rates, exemptions, and corporate tax obligations.

Nigeria Tax Administration Act (NTAA)

This act standardizes how taxes are administered across federal and state authorities, improving coordination and reducing inconsistencies in enforcement.

Nigeria Revenue Service Establishment Act (NRSA)

This law restructures Nigeria’s tax administration system by transforming the Federal Inland Revenue Service (FIRS) into the Nigeria Revenue Service (NRS) with broader authority to collect and administer taxes.

Joint Revenue Board Establishment Act (JRBA)

This act improves collaboration between federal and state tax authorities and helps reduce the burden of multiple taxation on businesses.

Together, these reforms aim to create a more efficient and transparent tax system for businesses operating in Nigeria.

Key Tax Changes Businesses Should Know in 2026

Higher Small Company Tax Threshold

One of the most important updates introduced in 2026 is the increase in the small company tax threshold.

Previously, businesses with annual turnover of ₦25 million or less were classified as small companies and exempt from Companies Income Tax.

Under the new reforms, the threshold increases significantly.

Businesses with annual turnover of ₦100 million or less are now classified as small companies and may qualify for exemptions from:

Companies Income Tax (CIT)
Capital Gains Tax (CGT)
Certain development levies

This change is intended to support startups and small businesses by reducing their tax burden and allowing them reinvest more resources into growth.

Changes to Capital Gains Tax

Capital Gains Tax (CGT) rules have also been updated.

Previously, CGT was typically charged at 10% on gains from asset disposals.

Under the new system:

Corporate capital gains may align more closely with corporate income tax rates
Gains from digital and virtual assets are now taxable
Tax authorities have introduced clearer rules preventing businesses from reclassifying profits as capital gains to reduce tax obligations

Businesses involved in asset sales, investments, or digital assets should review how these changes affect their tax obligations.

Expansion of Taxable Income

Nigeria’s tax reforms also expand the definition of what constitutes taxable income.

Income categories that may now be taxable include:

Digital asset income
Grants and honoraria
Awards and prizes
Certain non-traditional income sources

This reflects the growth of Nigeria’s digital economy and evolving income streams.

Increased Digital Tax Compliance

Nigeria is also moving toward a more digital tax administration system.

Businesses are increasingly expected to adopt systems that support:

Electronic invoicing
Digital transaction records
Automated VAT tracking
Real-time financial reporting

Large companies are already expected to adopt electronic invoicing systems, and these requirements may gradually extend to more businesses over time.

Simplification of Multiple Levies

Historically, Nigerian businesses have struggled with multiple overlapping taxes and levies imposed by different government agencies.

The new tax reforms aim to simplify this system by consolidating several levies into a more streamlined development levy structure.

This helps reduce administrative complexity and makes tax compliance easier for businesses.

Updated Personal Income Tax Structure

The reforms also introduce adjustments to Nigeria’s personal income tax framework.

The updated system follows a progressive tax structure, meaning tax rates increase gradually based on income level.

This approach aims to:

Reduce the burden on lower-income earners
Improve fairness in the tax system
Ensure higher-income individuals contribute proportionately

Employees and self-employed professionals should ensure their income records and deductions are properly documented when filing taxes.

What Businesses Should Prepare for in 2026

Nigeria’s updated tax system places a stronger emphasis on documentation, transparency, and compliance.

Businesses should take several steps to prepare.

Maintain Accurate Financial Records

Businesses should maintain clear records of:

Revenue and expenses
VAT transactions
Payroll records
Business operating expenses
Asset purchases and disposals

Good record keeping makes tax filing easier and reduces the risk of compliance issues.

Review Your Business Classification

Companies should determine whether they qualify under the new ₦100 million small company threshold.

This classification affects tax obligations, filing requirements, and possible exemptions.

Adopt Digital Accounting Systems

With Nigeria moving toward digital tax administration, businesses should consider adopting accounting systems that support:

Automated bookkeeping
Electronic invoicing
VAT tracking
Financial reporting

These tools reduce errors and simplify tax filing.

Understand Tax Filing Deadlines

Companies should stay aware of deadlines for:

Companies Income Tax filing
VAT returns
PAYE remittances
Annual tax returns

Meeting deadlines helps avoid unnecessary penalties.

Common Tax Filing Mistakes Businesses Make

Some of the most common tax filing mistakes include:

Failing to properly register with tax authorities
Mixing personal and business finances
Poor financial documentation
Missing filing deadlines
Incorrect VAT calculations

Avoiding these issues can save businesses significant time and money.

Final Thoughts
