How to Register Your Business for Tax in Nigeria: A Step-by-Step Guide
Tax registration used to be a headache. Separate applications. Multiple IDs. Confusing processes.
Not anymore.
Big changes arrived on January 1, 2026. Your RC Number is now your Tax ID. No separate TIN application. No extra cards. No juggling multiple numbers.
The system is simpler. But you still need to know the steps.
Let me walk you through exactly how to register your business for tax in Nigeria under the new rules.
What is tax compliance?
Here is the simple version.
Tax compliance means knowing what taxes you owe, calculating them correctly, filing your returns on time, and paying what you owe.
In Nigeria, tax compliance became even more critical after four major tax reform laws were passed in June 2025. These reforms simplify tax collection, reduce the burden on compliant businesses, and create a more transparent system.
Proper tax compliance is not just a legal matter. It affects your financial health, long-term success, and industry reputation.

2025-2026 tax reforms: what changed
On June 26, 2025, President Bola Ahmed Tinubu signed four tax bills into law:
-
The Nigeria Tax Act
-
The Nigeria Tax Administration Act
-
The Nigeria Revenue Service (Establishment) Act
-
The Joint Revenue Board (Establishment) Act
Simplified tax identification system
Expanded small company benefits
Small companies are now exempt from Companies Income Tax, Capital Gains Tax, and the newly introduced Development Levy. Small companies are defined as those with annual gross turnovers of ₦100 million or less and total fixed assets not exceeding ₦250 million. This is a significant increase from the previous threshold of ₦25 million.
Introduction of the Development Levy
Nigerian companies, except small companies, will pay a Development Levy at 4% of their assessable profits. This levy consolidates the Tertiary Education Tax, Information Technology Levy, NASENI levy, and Police Trust Fund levy.
Enhanced digital compliance requirements
The new law requires a mandatory fiscalisation system and e-invoicing with real-time validation via the Merchant Buyer Solution. VAT invoices must include your business registration number and sequential numbering.
Step-by-step guide to tax registration
Now, let me walk you through the complete process.
Step one: Register your business with CAC
Before you can register for tax, you must have a legally registered business entity.
Visit the CAC portal at https://services.cac.gov.ng. Choose your business structure, such as sole proprietorship, partnership, or limited liability company. Complete the online registration form. Submit the required documents, including the memorandum and articles of association and identification documents. Pay the registration fees. Receive your RC Number upon approval.
Important note: With the 2026 reforms, your RC Number automatically serves as your Tax ID. This eliminates the need for separate TIN registration for incorporated businesses.
Our CAC registration services can help you complete this step smoothly.
Step two: Obtain your TIN for pre-2026 registrations
If your business was registered before the reforms took effect, you still need to obtain a TIN.
Visit the Nigeria Revenue Service website or the designated tax office. Complete the TIN application form. Provide valid identification such as National ID, International Passport, or Driver’s License. Provide a utility bill or proof of address. Submit your CAC certificate, Memorandum, and Articles of Association. Submit your application online or at the nearest tax office. Receive your TIN certificate within 5 to 10 working days.
For 2026 and beyond, when you open a business account, you provide your RC Number. That same number covers both your business registration and tax compliance. The transition is automatic on the government’s side.
Step three: Register for Value Added Tax
If your business deals in taxable goods or services, you must register for VAT.
Complete the VAT registration form on the NRS portal. Provide your TIN or RC Number. Submit your business registration documents. Specify the nature of your business activities.
Step four: Register for PAYE if you have employees
If you have employees, you must register for PAYE to deduct and remit income tax from salaries.
Visit the State Internal Revenue Service office where your business operates. Complete the PAYE registration form. Provide your certificate of incorporation, TIN certificate, list of employees, and the company’s memorandum and articles of association. Receive your PAYE registration number.
The new law introduces a tax exemption for employees earning ₦800,000 or less annually. Progressive rates apply to higher income brackets. The tax rate ranges from 0% to 25%.
Step five: Register for Withholding Tax
Businesses making certain types of payments must deduct and remit WHT.
Apply through the NRS portal. Provide your business registration documents. Submit your TIN or RC Number. Specify the types of transactions your business conducts.
On February 24, 2025, FIRS issued a circular detailing guidelines for implementing the WHT Regulations 2024. These became effective for transactions from January 1, 2025. WHT applies to companies, partnerships, statutory and non-statutory bodies, unincorporated persons, and non-resident persons involved in transactions requiring tax deduction at source.
Step six: Register for VASP compliance if applicable
For businesses dealing with digital or virtual assets, additional registration is required.
Important compliance requirements after registration
Once you have completed your tax registration, ongoing compliance is essential.
Company Income Tax. File annual tax returns within 6 months after your financial year end. Pay provisional tax in instalments. Maintain proper accounting records.
Value Added Tax. File monthly VAT returns. Remit collected VAT to NRS. Implement mandatory e-invoicing system with real-time validation.
PAYE. Deduct tax from employee salaries monthly. Remit to State Internal Revenue Service within 10 days of the following month. File annual returns.
Withholding Tax. Deduct WHT at the point of payment. Remit within 21 days. Issue WHT certificates to beneficiaries. File monthly returns.
Digital compliance and record keeping
Under the new tax regime, digital compliance is mandatory. Implement accounting systems capable of e-invoicing. Set up real-time VAT reporting. Maintain electronic recordkeeping. Ensure your ERP systems align with NRS requirements.
The harmonisation of Nigeria’s disparate tax landscape while embracing digital modernisation is an innovative feature of the Tax Laws. Successful implementation will largely depend on judicial clarity on potential constitutional questions and robust infrastructure.
Our digital compliance advisory can help you implement the required e-invoicing and reporting systems.
Penalties for non-compliance
Understanding consequences helps motivate proper registration and ongoing compliance.
Failure to register for tax attracts fines and potential business closure. Late filing of returns incurs interest charges and penalties. Under declaration of income brings penalties plus interest on tax owed. Failure to remit deducted taxes can lead to criminal prosecution in severe cases. VASP non-compliance costs ₦10 million initial penalty and ₦1 million monthly thereafter.
The Nigeria Tax Administration Act 2025 introduces stiffer penalties for employers that under deduct taxes or delay remittance. Compliance is more critical than ever.
Benefits of proper tax registration and compliance
Legal protection. Operating with proper tax registration protects your business from legal issues, fines, and potential closure.
Access to government contracts. Many government tenders and contracts require tax compliance certificates before you can bid.
Easier access to financing. Banks and investors often require proof of tax registration and compliance before extending credit or investment.
Business credibility. Tax compliance demonstrates financial responsibility and builds trust with stakeholders, customers, and partners.
Tax incentives and benefits. Compliant businesses can access various tax incentives, exemptions, and deductions under Nigerian tax law.
Simplified operations. With the new unified TIN system using your RC Number, business operations become significantly more streamlined.
Our audit and assurance services can help you maintain the financial records needed for compliance.
Tips for smooth tax registration and compliance
Engage professional help. Consider hiring a tax consultant or accountant familiar with Nigerian tax laws, especially during the transition to the new system.
Keep accurate records. Maintain detailed financial records from day one. This makes tax filing and compliance much easier.
Stay informed. Monitor updates from the Nigeria Revenue Service and official gazette publications to stay informed on effective dates, transitional reliefs, and implementation guidelines.
Invest in technology. Implement accounting software that can handle e-invoicing, real-time reporting, and electronic recordkeeping.
Plan for the transition. Review your current tax structure and prepare your systems for the changes.
File and pay on time. Set up calendar reminders for all filing and payment deadlines to avoid penalties.
Understand your tax category. Determine if your business qualifies as a small company under the new threshold to take advantage of available exemptions.
At Stonehill Research , we provide ongoing advisory to keep you compliant as regulations evolve.
Special considerations for different business types
Small companies
If your business has an annual turnover of ₦100 million or less and fixed assets below ₦250 million, you qualify as a small company. However, the Nigeria Tax Act 2025 provides a 0% CIT rate for small companies but explicitly excludes sectors such as professional service providers. Companies must carefully assess their sector classification and income composition. Mixed operations or engagement in excluded industries could forfeit eligibility.
Professional service providers
Legal, accounting, medical practices, and other professional services do not qualify for small company exemptions regardless of turnover. They must pay applicable taxes.
Foreign companies
Non-resident companies supplying goods or services in Nigeria must register for VAT and comply with withholding tax requirements.
