Tax Penalties in Nigeria: Mistakes Businesses Make on the New Portal-Part 2

Introduction To Tax Penalties In Nigeria

As of January 1, 2026, Nigeria has entered a new fiscal era with the full implementation of the Nigeria Tax Reform Acts 2025 which provide tax penalties, fines, and interest for non-compliance. These reforms represent a massive structural reset of the country’s tax system, consolidating several older laws including the Companies Income Tax Act and Personal Income Tax Act into a unified framework designed to simplify compliance and promote business growth.

The reform consists of four distinct Acts that work together to create a more streamlined tax environment:

Nigeria Tax Act (NTA): Consolidates federal tax laws and defines taxable items and rates
The Nigeria Tax Administration Act (NTAA): Creates a unified framework for tax administration
Nigeria Revenue Service (Establishment) Act (NRSA): Establishes the Nigeria Revenue Service (NRS) as the central federal tax collection body
Joint Revenue Board (Establishment) Act (JRBA): Coordinates tax harmonisation across government levels

As we move further into 2026, the grace period for manual tax processes in Nigeria has officially ended. The Nigerian Tax Administration Act (NTAA) 2025 has fully shifted the landscape from “paper-heavy” to “digital-first.” At the heart of this transformation is the New Tax Portal, a unified system designed to ensure every kobo is accounted for in real-time.

For businesses that have yet to link their operations to this portal or adopt the mandated fiscalisation tools, the legal and financial risks are no longer theoretical—they are substantial and immediate.

Understanding Who Must Comply With Tax Penalties in Nigeria: The Definition of “Taxable Person

Before examining the tax penalties, it is crucial to understand who falls under the obligation to register and link to the portal. Section 202 of the Nigeria Tax Act 2025 provides a comprehensive definition:

“taxable person” includes a company, individual or body of individuals, family, community, corporations sole, trustee, executor or any other legal arrangement, or any person who earns income, or carries out an economic activity, a person exploiting tangible or intangible property for the purpose of obtaining income there from by way of trade or business, or any person or agency of government acting in that capacity.

This definition is intentionally broad and all-encompassing. It covers not just registered companies but also sole proprietors, partnerships, family businesses, trustees, executors of estates, and even government agencies engaged in commercial activities. If you earn income or conduct any form of economic activity in Nigeria, you are considered a taxable person under the law.

The implication is clear: whether you operate a multinational corporation, run a small retail shop, provide freelance services, or manage rental properties, you fall within the scope of this definition. There are virtually no exemptions based on business size or structure. The tax reform has deliberately cast a wide net to bring all economic actors into the formal tax system.

Penalty for Failure to Register for Tax

One of the foundational requirements under the new tax regime is registration. Section 100(1) of the Nigerian Tax Administration Act 2025 establishes clear tax penalties for non-compliance:

100. (1) A taxable person who fails or refuses to register for tax under section 4 of this Act, shall be liable to pay an administrative penalty of –

(a) ₦50,000 in the first month in which the failure occurs; and

(b) ₦25,000 for each subsequent month in which the failure continues.

This means that registration is no longer optional or something you can postpone indefinitely. The moment you meet the criteria of a taxable person and fail to register through the New Tax Portal, you immediately incur a penalty of ₦50,000 for the first month of non-compliance.

More importantly, the penalty doesn’t stop there. For every additional month that you remain unregistered, you accumulate an additional ₦25,000 in penalties. This creates a cumulative financial burden that grows with time. For example, if a business remains unregistered for six months, the total penalty would be ₦175,000 (₦50,000 + ₦25,000 × 5 months).

These escalating structures for tax penalties is designed to incentivise immediate compliance. The law recognises that some businesses may genuinely be unaware of their obligations initially, hence the relatively modest first-month penalty. However, continued failure to register is treated as deliberate non-compliance, warranting progressively stricter enforcement.

Penalty for Failure to Use the Fiscalisation System

Beyond registration, the new tax regime requires businesses to process all taxable supplies through an approved fiscalisation system. Section 104 of the Nigerian Tax Administration Act 2025 imposes severe consequences for non-compliance:

Section 104 states that:

104. A taxable person that fails to process a taxable supply through the fiscalisation system is liable to an administrative penalty of ₦200,000 plus 100% of the tax due and an interest at the prevailing Central Bank of Nigeria Monetary Policy rate per annum.

This provision targets businesses that may have registered but are not using the mandated fiscalisation tools to record and report their transactions in real-time. Fiscalisation systems typically include electronic invoicing, point-of-sale systems, and other digital tools that automatically capture transaction data and transmit it to the tax authorities. In in Nigeria, this system is the new tax portal.

Tax Penalties Listed

The tax penalties listed are particularly punitive and multi-layered:

Fixed Administrative Penalty: An immediate ₦200,000 fine is imposed for each instance of failure to process a transaction through the fiscalisation system.
100% Tax Surcharge: In addition to the administrative penalty, you must pay double the actual tax that should have been remitted—the original tax due plus an additional 100% as a surcharge. This means if your tax liability on a transaction was ₦500,000, you would pay ₦1,000,000 in total.
Interest on Unpaid Tax: On top of both the penalty and the surcharge, interest accrues on the unpaid tax at the Central Bank of Nigeria’s Monetary Policy Rate (MPR). As of early 2026, this rate stands at approximately 27.5% per annum, making the cost of non-compliance extraordinarily expensive over time.

To illustrate the full impact: suppose a business processes a taxable supply of ₦5,000,000 outside the fiscalisation system, with a tax component of ₦375,000 (assuming 7.5% VAT). The total penalty would be:

Administrative penalty: ₦200,000
Original tax due: ₦375,000
100% surcharge: ₦375,000
Interest (assuming 6 months at 27.5% MPR): approximately ₦51,562

Total liability: ₦1,001,562 for what should have been a ₦375,000 tax obligation.

This severe penalty regime serves multiple purposes: it discourages tax evasion, promotes transparency in business transactions, ensures real-time tax collection, and creates a level playing field for all businesses by making non-compliance financially unsustainable.

The Broader Implications

These penalties represent more than just financial costs. Non-compliance can lead to:

Reputational damage: Businesses flagged for non-compliance may find it difficult to secure contracts, especially with government agencies or multinational corporations that require tax compliance certificates.
Operational disruptions: Tax authorities have enhanced powers under the NTAA to enforce compliance, including the ability to seal premises or freeze bank accounts.
Personal liability for directors: In certain circumstances, company directors may be held personally liable for corporate tax obligations, putting personal assets at risk.
Difficulty accessing financial services: Banks and other financial institutions increasingly require proof of tax compliance before approving loans or other facilities.

Conclusion

In 2026, the Nigerian tax system is no longer a game of “catch me if you can.” With the automated tracking provided by the New Tax Portal and mandatory fiscalisation systems, being invisible is no longer an option, it is a red flag that triggers immediate regulatory attention.

Linking your business to the portal and adopting approved fiscalisation tools isn’t just about modernising your operations; it’s about protecting your business from crippling tax penalties, ensuring your directors aren’t personally liable for multi-million naira fines, and securing your company’s ability to operate freely in Nigeria’s increasingly digital economy.

The message from the Nigeria Revenue Service is unambiguous: compliance is mandatory, tax penalties are automatic, and the cost of non-compliance far exceeds the effort required to get it right. The question is no longer whether to link your business to the New Tax Portal, but how quickly you can complete the process.

For businesses still operating outside the system, the time to act is now. Every day of delay adds to your financial exposure and regulatory risk. In the new Nigeria tax landscape, compliance is not just the right thing to do—it’s the only sustainable path forward.
