Tax Services
Our Tax Services provide businesses with end-to-end support for understanding, managing, and fulfilling all statutory tax obligations under Nigerian law. We help you stay fully compliant with federal and state tax authorities, avoid penalties, optimise liabilities, and ensure your operations run smoothly within the regulatory framework of the Nigeria Revenue Service (formerly FIRS) and relevant State Internal Revenue Services.
1. Tax Registration & Identification
Before any compliance activity, your business must be properly registered with the appropriate tax authorities. We assist with:
Obtaining your Tax Identification Number (TIN) — mandatory for all formal tax filings.
Registering for VAT (Value Added Tax) with the Nigeria Revenue Service.
This foundational step ensures your company meets its legal obligations from day one.
2. Statutory Tax Compliance & Filing
We manage the preparation, calculation, and submission of all required tax returns on your behalf, including:
• Corporate Income Tax (CIT)
All companies registered in Nigeria must file an annual income tax return within six months after the end of their financial year. This includes tax computations, audited financials, and supporting schedules as required by law.
• Value Added Tax (VAT)
VAT is charged at 7.5% on most goods and services. Businesses must file VAT returns and remit amounts collected on or before the 21st day of each month following the supply period. Strict deadlines apply, and late filings attract penalties.
• Withholding Tax (WHT)
Where applicable, companies must deduct withholding tax from payments for professional services, contracts, rents, commissions, and more, and remit it to the tax authorities by the 21st day of the month after the deduction.
• Personal Income Tax (PAYE)
Employers act as agents of the tax authorities to deduct Pay-As-You-Earn (PAYE) from employees’ salaries and remit these to the relevant State Internal Revenue Service (e.g., LIRS in Lagos) before the 10th day of the month after payroll deductions.
• Other Returns & Filings
We also handle remittances and returns for education tax, stamp duties, capital gains tax (where relevant), and other statutory levies, ensuring no obligation is overlooked.
3. Tax Advisory & Strategic Planning
Beyond compliance, we offer proactive tax planning to help you optimise your tax position, including:
Identifying available incentives, exemptions, and reliefs under Nigerian tax laws.
Structuring business activities to maximise tax efficiency within legal boundaries.
Advising on complex matters such as transfer pricing, cross-border transactions, and tax implications of business restructuring.
4. Representation & Audit Support
If your business is selected for tax audit or review, we represent you before the Nigeria Revenue Service or State tax authorities, assist with information requests, respond to investigations, and help resolve disputes.
