Would You Pass a Compliance Check Today?

A Practical Guide to Tax Compliance, Professional Tax Filing, Tax Credits and Regulatory Readiness for Businesses in Nigeria

For many business owners, tax compliance is often treated as something to address when a filing deadline approaches. In practice, compliance is an ongoing process.

A business may be generating revenue, paying employees, issuing invoices and making purchases every month while important tax obligations remain incomplete, incorrectly calculated or unsupported by adequate records.

That raises an important question:

If your business were asked today to demonstrate that its tax affairs are properly managed, would the records, filings and supporting documents tell a consistent story?

This is the essence of a compliance check.

Nigeria's tax administration framework has also changed significantly. The Nigeria Tax Act, 2025 and Nigeria Tax Administration Act, 2025 commenced from 1 January 2026 and form part of the current federal tax framework. The Nigeria Revenue Service (NRS) provides taxpayers with access to tax services, tax laws, returns, tax calendars, penalties and compliance information.

For businesses, therefore, tax compliance should not be approached simply as the act of submitting a return. It involves understanding the applicable law, maintaining reliable records, calculating liabilities correctly, filing within the applicable periods and retaining evidence to support the position reported.

What Does Tax Compliance Mean for a Business in Nigeria?

Tax compliance generally means meeting the obligations imposed by applicable tax legislation and administrative requirements.

Depending on the nature and activities of the business, these obligations may include:

• Registration with the appropriate tax authority.
• Obtaining and maintaining the required tax identification information.
• Filing applicable tax returns.
• Correct computation of taxable income and tax liabilities.
• VAT compliance where applicable.
• Withholding Tax obligations where applicable.
• PAYE obligations for employers.
• Capital gains tax considerations where relevant.
• Stamp duty obligations on applicable instruments and transactions.
• Keeping accounting records and supporting documentation.
• Paying assessed taxes within the applicable statutory period.
• Responding appropriately to notices, queries or assessments from the tax authority.
• Maintaining documentation supporting deductions, exemptions, reliefs and tax credits claimed.

The exact obligations depend on the taxpayer, business structure, turnover, activities, transactions and applicable legislation.

The NRS currently lists company income tax, individual income tax, VAT, withholding tax and stamp duties among its tax services and publishes relevant tax laws and compliance resources.

Why Should Every Business Take Tax Compliance Seriously?

Tax compliance is not merely an accounting exercise.

It forms part of the governance framework of a business.

1. It establishes a reliable tax position

A business should be able to explain how its reported turnover, expenses, profit, payroll, VAT and other relevant tax figures were determined.

When accounting records and tax returns are prepared from incomplete information, inconsistencies can arise.

A properly maintained tax file creates an evidence trail between:

Business transactions → accounting records → tax computation → tax return → payment evidence.

That connection matters.

2. It helps reduce avoidable filing errors

Tax calculations can involve statutory definitions, thresholds, exclusions, deductions, exemptions, timing rules and documentation requirements.

A small classification error can affect a tax computation.

For example, an expense recorded in the accounts does not automatically mean that the entire amount is deductible for tax purposes. Tax treatment must be determined under the applicable law.

Professional review can help identify issues before a return is submitted.

3. It supports timely compliance

Businesses have different filing and payment obligations.

Waiting until the deadline can create unnecessary pressure, particularly where accounting records are incomplete or information must be obtained from several departments.

A structured compliance calendar allows the business to monitor:

• Filing dates.
• Payment dates.
• Payroll obligations.
• VAT obligations.
• WHT obligations.
• Annual tax returns.
• Tax clearance requirements.
• Regulatory correspondence.
• Documentation renewal requirements.

The NRS maintains a tax calendar and compliance resources for taxpayers.

4. It creates better documentation for tax queries

If a tax authority requests clarification, the quality of the underlying records becomes important.

A business should be able to produce appropriate evidence for relevant transactions, such as:

• Invoices.
• Receipts.
• Contracts.
• Bank statements.
• Payroll records.
• Expense schedules.
• WHT evidence.
• VAT records.
• Fixed asset schedules.
• Import and export documentation where relevant.
• Tax computations.
• Previous returns.
• Payment receipts.
• Correspondence with tax authorities.

Good documentation does not eliminate the possibility of a tax query. It does, however, provide an evidential basis for explaining the business's tax position.

Why Consider Using a Professional Tax Consulting Firm?

A business owner is legally responsible for the company's affairs, but tax compliance can involve technical accounting and legal considerations.

Using a qualified professional does not transfer the taxpayer's legal responsibility. Instead, it can provide additional technical review and administrative support.

A professional tax consulting firm may assist with:

Tax computation

The professional can review accounting information and determine the applicable tax treatment based on the relevant legislation.

Return preparation

Tax returns can be prepared from verified accounting information and supporting schedules.

Compliance review

A review may identify missing filings, inconsistent figures, unsupported deductions or other matters requiring attention.

Tax reconciliation

Tax records can be compared with accounting records, prior returns, payment evidence and available information on the relevant tax platform.

Legislative monitoring

Tax laws and administrative procedures can change. Professional advisers can help businesses monitor developments relevant to their operations.

Documentation

A properly organised tax working file can make it easier to understand how reported figures were derived.

Communication with tax authorities

Where professionally appropriate and authorised by the taxpayer, a tax consultant may assist with correspondence, clarification of assessments and other tax administration matters.

The objective should not be to create an artificial tax position. The objective is to help the taxpayer understand and correctly apply the law.

What Can Go Wrong When Tax Returns Are Prepared Without Adequate Review?

Consider a business that reports ₦100 million in sales in its accounting records but submits a tax return based on an incomplete sales schedule.

The issue may not be intentional.

Perhaps:

• One bank account was omitted.
• Some invoices were not captured.
• A credit note was incorrectly treated.
• A VAT transaction was classified incorrectly.
• WHT credits were not properly reconciled.
• An expense was deducted without sufficient supporting evidence.
• Foreign transactions were not properly reviewed.
• Payroll figures did not agree with accounting records.

These are examples of why reconciliation is important.

The objective of professional tax filing should be accuracy, consistency, documentation and compliance—not simply submission before a deadline.

Why Every Business Should Comply With Tax Regulations

Tax compliance has implications beyond the payment of tax.

1. It supports business governance

A company that maintains proper tax records is better positioned to understand its financial obligations.

Tax should form part of the business's financial control system rather than operate separately from accounting.

2. It helps manage statutory exposure

The Nigeria Tax Administration Act, 2025 provides the framework for tax administration, including procedures relating to assessment, collection, payment and administration of taxes.

Businesses should therefore understand their obligations rather than assume that non-filing or late filing is inconsequential.

The NRS also expressly provides information concerning penalties, sanctions and enforcement actions.

3. It supports financial transparency

Tax returns should be capable of being reconciled to the business's underlying financial records.

Where accounting information, bank transactions, invoices and tax filings are materially inconsistent, management may have difficulty explaining the company's financial position.

4. It supports applications and commercial processes

Tax documentation may become relevant when a business is dealing with:

• Banks and financial institutions.
• Investors.
• Government contracts.
• Regulatory processes.
• Corporate transactions.
• Business expansion.
• Foreign investors.
• Due diligence exercises.

The precise documents required depend on the transaction or institution involved.

Tax Compliance Checklist: Would Your Business Pass a Basic Review?

Ask these questions:

• Are all applicable tax registrations current?
• Are required tax returns being filed?
• Are tax filings consistent with the accounting records?
• Are bank transactions reconciled?
• Are VAT records properly maintained where applicable?
• Are WHT deductions and credits properly reconciled?
• Are PAYE obligations properly accounted for where applicable?
• Are deductible expenses supported by appropriate documentation?
• Are tax payments supported by evidence?
• Are previous tax filings and assessments properly retained?
• Are outstanding tax authority queries being addressed?
• Are tax computations reviewed before submission?
• Is the business monitoring changes in tax legislation?
• Are available statutory exemptions, deductions, reliefs or incentives being considered where the business qualifies?
• Can management explain how the figures in the latest tax return were calculated?

If several answers are "No" or "I am not sure," the business may benefit from a structured tax compliance review.

Tax Credits, Reliefs and Opportunities Businesses Should Understand

Tax compliance is not only about determining what a taxpayer owes.

It also involves understanding legitimate statutory deductions, exemptions, reliefs and incentives for which a taxpayer may qualify.

However, a tax incentive should never be claimed merely because it appears beneficial.

Eligibility conditions, documentation, application procedures, sector requirements and statutory limitations must first be considered.

Economic Development Tax Incentive

The Nigeria Tax Act, 2025 introduced the Economic Development Tax Incentive (EDTI) framework, replacing the previous Pioneer Status Incentive framework for new applications from the commencement of the new regime.

The NIPC states that the EDTI is linked to qualifying capital expenditure and priority sectors or products. The Act provides for an economic development tax credit of 5% per annum for five years in respect of eligible qualifying capital expenditure, subject to the statutory conditions.

NIPC has also published application guidance for the EDTI, including application procedures, due diligence and beneficiary obligations.

This is an important example of why businesses should review tax law before making investment and tax decisions.

Foreign Tax Credit

Businesses and individuals with qualifying foreign income may also need to consider the rules governing relief from double taxation.

The Nigeria Tax Act contains provisions dealing with tax credits under applicable arrangements, including limitations on the amount of credit that may be available. The statutory requirements should be examined before a credit is claimed.

This is particularly relevant to businesses involved in cross-border transactions.

Research and Development Expenditure

The Nigeria Tax Act, 2025 also contains provisions dealing with deductions for qualifying research and development expenditure. The statutory conditions and documentation requirements should be considered when determining whether expenditure qualifies.

Capital Allowances and Other Statutory Reliefs

Businesses should distinguish between:

Accounting treatment and tax treatment.

An asset may be depreciated in the financial statements, while the tax treatment is determined according to applicable capital allowance or other statutory provisions.

This distinction should be incorporated into the tax computation.

Tax Law Matters: Why Business Owners Should Not Rely on Old Information

One of the practical challenges facing Nigerian businesses is relying on information that was correct under an earlier tax regime but is no longer current.

From 1 January 2026, the Nigeria Tax Act, 2025 and Nigeria Tax Administration Act, 2025 became central parts of the new federal tax framework.

This means that businesses should review older tax procedures, templates and assumptions.

A tax computation prepared using an outdated rule can produce a technically incorrect result even when the arithmetic itself is correct.

That is why tax compliance requires current legal knowledge as well as accurate accounting information.

Tax Compliance Is Also About Internal Controls

A business should not leave tax entirely to the person who submits the return.

Management can establish simple internal controls such as:

Monthly reconciliation

Compare sales records, bank receipts, invoices and accounting entries.

Expense documentation

Require appropriate evidence before significant expenses are posted.

WHT tracking

Maintain a schedule showing transactions subject to WHT, amounts deducted and available evidence or credits.

VAT reconciliation

Where applicable, reconcile VAT records with sales and purchase documentation.

Payroll reconciliation

Compare payroll records with accounting entries and applicable PAYE obligations.

Tax calendar

Maintain a central compliance calendar with responsibility assigned to specific personnel.

Review before filing

Have tax computations and returns reviewed before submission.

These controls can make tax compliance a normal part of business administration rather than an emergency exercise at the end of a filing period.

What Should a Business Owner Do Before the Next Tax Filing?

A practical approach is to work through five stages:

Stage 1: Establish the facts

Determine the company's turnover, activities, employees, assets, transactions and applicable registrations.

Stage 2: Reconcile the records

Reconcile accounting records with bank statements, sales schedules, invoices, payroll and relevant tax records.

Stage 3: Identify tax obligations

Determine which taxes, returns, deductions, payments and reporting requirements apply.

Stage 4: Review the law

Check the current legislation and applicable administrative guidance.

Stage 5: File and retain evidence

Submit accurate returns within the applicable period, make required payments and retain supporting documentation.

This approach creates a defensible compliance process.

A Professional Tax Consultant Should Not Replace Management's Responsibility

It is important to maintain a proper distinction.

A professional adviser can provide tax advice, computation, review and compliance support, but management remains responsible for providing complete and accurate information about the business.

Professional tax assistance should therefore involve:

Complete information + appropriate professional competence + current legislation + proper documentation + management oversight.

That is a more sustainable approach than simply asking someone to "file the tax."

Where US & CO. (Chartered Accountant) Fits Into the Compliance Process

US & CO. (Chartered Accountant) can be mentioned in the context of professional tax compliance support where such assistance is required.

The appropriate approach is not to promise a particular tax outcome or suggest that professional engagement removes statutory obligations.

Instead, a business may engage a professional accounting or tax practice to assist with matters such as:

• Tax compliance review.
• Tax computation.
• Tax return preparation.
• Tax reconciliation.
• VAT and WHT compliance support.
• PAYE compliance support.
• Tax documentation.
• Tax advisory services.
• Review of applicable statutory reliefs and incentives.
• Assistance with tax correspondence and clarification, where authorised.

Professional communication should remain factual and transparent. ICAN guidance states that publicity for professional services should be honest and truthful, should not contain exaggerated claims, and should not disparage other firms or make unsubstantiated comparisons.

Accordingly, the appropriate message is simple:

Good tax compliance starts with accurate records, correct interpretation of applicable law and timely action.

Final Thought: The Real Compliance Test

A tax compliance check is not simply about whether a return was submitted.

The more meaningful questions are:

Was the return accurate?

Can the figures be reconciled to the accounting records?

Can the business support the deductions and claims it made?

Were the applicable tax laws considered?

Were taxes paid within the required period?

Can the business produce the underlying evidence if asked?

If the answer to these questions is yes, the business has taken important steps toward maintaining an organised tax compliance position.

If the answer is uncertain, now is a suitable time to review the records rather than waiting for a tax query or deadline.

Tax compliance should be treated as a continuous business responsibility—not a once-a-year activity.
