Did you know that thousands of businesses have had their accounts frozen for failing to remit taxes. Such a penalty can cripple even a thriving business. Prevention, in this case, is far more affordable than cure.
Running a business in Nigeria is no small feat, from managing staff members to scaling operations. But one challenge that often trips up even the fastest growing businesses is taxes. So ignoring terms like VAT, CIT, PAYE, and WHT may lead to heavy penalties.
In this guide, we break down everything Nigerian business owners need to know about these core taxes, including Value Added Tax (VAT), Company Income Tax (CIT), Pay As You Earn (PAYE), and Withholding Tax (WHT).
VAT, CIT, PAYE, WHT: An Overview of Key Tax Types
Here’s a quick overview of the major tax categories Nigerian business owners need to understand:
- VAT (Value Added Tax): A consumption tax charged at 7.5% on goods and services. Businesses are required to charge VAT on sales, remit it to FIRS, and file monthly returns, even if no VAT was collected.
- CIT (Company Income Tax): Tax on a company’s profits. Rates vary from 0% to 30% depending on your turnover, with exemptions for small businesses earning less than ₦25 million annually.
- PAYE (Pay As You Earn): A system where employers deduct personal income tax from employees’ salaries and remit it monthly to the state tax authorities.
- WHT (Withholding Tax): A form of advance tax deducted at source on specific transactions (e.g., rent, dividends, contract payments). It’s meant to reduce tax evasion and is later credited against the final tax liability.
Why Business Owners Must Understand Tax Obligations in Nigeria
For Nigerian business owners, understanding tax obligations helps to protect your business, planning effectively, and maintaining credibility with stakeholders. As a corporate entity, tax compliance affects your finances, access to credit, and eligibility for government contracts or investment opportunities. Taxes like VAT, CIT, PAYE, and WHT directly impact your cash flow and decision-making, so being well-informed is critical.
Non-compliance with tax laws can result in serious consequences, including:
- Hefty fines and interest on unpaid taxes
- Freezing of business bank accounts by FIRS or state IRS
- Loss of business licenses or regulatory approval
- Negative publicity and reputational damage
- Legal action or court summons
How Taxation Supports National Development
Taxation is not just a legal obligation but a vital engine for national growth and public service delivery. In Nigeria, taxes like VAT, CIT, PAYE, and WHT provide the government with the revenue needed to build and maintain the country’s infrastructure, security systems, healthcare, education, and social welfare.
1. Funding Public Infrastructure and Services
Revenue from taxes supports the construction and maintenance of roads, bridges, airports, and rail systems. For example, the Second Niger Bridge and parts of the Lagos-Ibadan Expressway were funded in part by tax allocations from the national budget.
2. Education and Healthcare Investment
Taxes help fund public universities, teaching hospitals, and health initiatives. In 2023, FIRS reported that a significant portion of PAYE collections contributed to increased budgetary allocations for public healthcare services across multiple states.
3. National Security and Governance
Defense, policing, and the judiciary are all sustained by tax revenue. These systems uphold law and order, which in turn create an environment where businesses can thrive.
4. Job Creation Through Government Spending
Government contracts awarded to private firms (often funded by CIT and VAT revenues) create employment and stimulate local economies. Construction, agriculture, ICT, and manufacturing benefit heavily from such public spending.
5. Economic Stability and Policy Implementation
Taxes give the government financial leverage to implement economic policies, offer subsidies, manage inflation, and stabilize the currency. For instance, the Nigerian government has used tax-funded stimulus packages to support SMEs during economic downturns, including during the COVID-19 pandemic.
6. Social Equity and Redistribution
Progressive tax systems like PAYE help redistribute wealth by requiring higher earners to pay a higher tax rate. These funds can be used to support vulnerable populations through welfare programs, free education, and healthcare access.
Taxation, therefore, plays a central role not just in running government operations, but also in creating the kind of environment where private businesses can succeed. Without it, basic systems would collapse, leaving businesses without the foundational support they need to grow.
What is VAT?
Value‑Added Tax (VAT) in Nigeria is a consumption tax applied at each stage of the supply chain on goods and services, ultimately borne by the final consumer. Governed by the VAT Act and enforced by FIRS, its purpose is to finance government projects, social services, and infrastructure.
Since 1 February 2020, the standard VAT rate in Nigeria has been 7.5%, up from 5%. A proposed increase to 10% was rejected by the Senate in May 2025.
Who Must Register for VAT?
- Any business with annual turnover of ₦25 million or more, based on a rolling 12‑month period.
- Non‑resident suppliers, including digital service providers to Nigerian customers, must also register.
- Businesses may also register voluntarily even if below the threshold.
How VAT is Collected and Remitted
- Registered businesses collect VAT at 7.5% on sales to Nigerian customers.
- B2B transactions: a reverse‑charge mechanism applies; buyers (with VAT numbers) self-account for VAT when a supplier doesn't charge VAT.
- Non‑resident suppliers must charge VAT on services or goods supplied to customers in Nigeria.
VAT Filing Timeline and Penalties
- VAT returns and payments are due monthly, by the 21st day of the month following the transaction period.
- Penalties for non‑compliance:
- ₦50,000 fine for the first month of default
- ₦25,000 for each additional month.
- ₦50,000 fine for the first month of default
VAT Exempt Items and Services
Nigeria distinguishes between zero‑rated and exempt supplies:
- Zero‑rated (0%): exports, goods/services for diplomats, humanitarian aid.
- Exempt: basic food items (bread, flour, vegetables, milk, cooking oil, fish, meat), medical & pharmaceutical products, educational books, baby products, farm equipment, and certain renewable energy items.
- Updates in 2020–2021 expanded exemptions to include residential rents (although later refined), passenger transport, certain agricultural and energy supplies.
Common Mistakes with VAT and How to Avoid Them
- Failing to register on time after crossing ₦25 million or entering binding contracts — leads to fines.
- Charging VAT but missing monthly remittances — triggers penalties of ₦50k + ₦25k/month.
- Incorrectly categorizing supplies (e.g., calling taxable goods "exempt") — may cause credit reclaim issues.
- Not issuing proper tax invoices — a requirement under section 13A of the VAT Act.
- Overlooking reverse‑charge VAT in B2B scenarios — leads to under-remittance.
- Ignoring reverse-charge and self-accounting obligations — especially for non-resident suppliers or suppliers below threshold.
Practical Tips to Stay Compliant
- Set monthly calendar reminders for the 21st filing deadline.
- Use FIRS’s TaxPro Max portal to file returns and monitor payments.
- Classify products/services correctly and stay updated on changes to exempt lists.
- Keep clean tax invoices—include TIN, VAT number, tax amount, invoice number/date.
- If below threshold, consider voluntary registration to gain vendor credibility and reclaim input VAT.
- Use Flex Finance to manage business spend for effective expense categorization to stay audit-ready always.
What is CIT?
Company Income Tax (CIT) is a tax levied on the profits of registered companies in Nigeria, both local and foreign, as defined under the Companies Income Tax Act (CITA), Cap C21 LFN 2004 (as amended). It is payable annually to the Federal Inland Revenue Service (FIRS).
CIT applies to all sectors except those specifically regulated under Petroleum Profit Tax (PPT), like upstream oil & gas.
CIT Rates for Different Business Categories
The Finance Act 2019 and subsequent amendments introduced a tiered tax rate system to ease the burden on small businesses:
Small Companies (Turnover < ₦25 million) – 0% CIT
- No CIT is charged.
- These companies are still required to file returns annually even if no tax is due.
- Example: A micro-agro-processing business earning ₦12 million annually.
Medium Companies (₦25M–₦100M) – 20% CIT
- Taxable on net profits at 20%.
- Must submit audited accounts and compute tax based on accounting profit adjusted for tax purposes.
- Example: A mid-sized logistics company generating ₦70 million per year.
Large Companies (> ₦100M) – 30% CIT
- Taxable at the standard rate of 30%.
- Example: A consumer goods manufacturing firm earning ₦150 million in annual turnover.
CIT Filing Requirements and Deadlines
- CIT is filed annually and must be submitted within six months after the end of the financial year or 18 months after incorporation for new companies.
- Late filing attracts:
- ₦25,000 penalty for the first month, and
- ₦5,000 for each subsequent month of default.
- ₦25,000 penalty for the first month, and
Required Filing Documents:
- Audited Financial Statements
- Tax Computation Schedule
- Capital Allowance Schedule
- Evidence of payment
- Company’s TIN and Tax Clearance Certificate
Allowable (Tax-Deductible) Expenses:
- Salaries and wages
- Rent and utility costs
- Repairs and maintenance
- Interest on business loans
- Marketing and advertising expenses
- Depreciation (via capital allowance)
Non-Allowable Expenses:
- Personal or non-business expenses
- Fines and penalties
- Donations not to government-approved bodies
- Capital expenditures (though these may qualify for capital allowances)
Capital Allowances and Tax Reliefs
Capital allowance is a tax relief granted on qualifying capital expenditures (QCEs) such as machinery, equipment, and buildings, instead of deducting depreciation.
Common Capital Allowances:
- Initial Allowance (granted in the first year): ranges from 5% to 95% depending on asset type
- Annual Allowance (given yearly until full cost is recovered)
For Example:
If you purchase a truck for ₦10 million:
- Initial Allowance: 50% (₦5 million)
- Annual Allowance: 25% of the remaining ₦5 million = ₦1.25 million/year
Tax reliefs include Investment Allowance, Pioneer Status Incentive (PSI) via Nigerian Investment Promotion Commission (NIPC) - 0% CIT for up to 5 years, Export Expansion Grant (EEG) via Nigerian Export Promotion Council (NEPC), Rural Investment Allowance, Research & Development Deduction.
How to Compute CIT: A Step-by-Step Example
Consider this scenario:
ABC Manufacturing Ltd has a turnover of ₦120 million and the following details for the year:
- Profit Before Tax (PBT): ₦30 million
- Non-allowable expenses included in accounts: ₦2 million
- Capital allowance: ₦5 million
Step 1: Adjust Accounting Profit
Taxable Profit = PBT + Non-Allowable Expenses = ₦30M + ₦2M = ₦32M
Step 2: Apply Capital Allowance
Taxable Profit after Capital Allowance = ₦32M – ₦5M = ₦27M
Step 3: Determine Applicable Rate
ABC Ltd is a large company, so apply 30% CIT.
Step 4: Compute CIT
₦27M × 30% = ₦8.1 million payable as CIT.
Company Income Tax (CIT) Penalties for Non-Compliance
Failure to comply with CIT regulations in Nigeria attracts monetary penalties, interest charges, and potentially legal consequences. Below are the common areas of non-compliance and the corresponding penalties under the Companies Income Tax Act (CITA) and FIRS regulations:
1. Failure to File CIT Returns
If a company fails to file its CIT returns within the specified timeframe:
- ₦25,000 for the first month of default
- ₦5,000 for each subsequent month the failure continues
Example: A business that fails to file for 6 months would incur:
₦25,000 + (₦5,000 × 5) = ₦50,000 total penalty.
2. Late Payment of Assessed Tax
If a company files but fails to pay assessed tax on time:
- 10% of the assessed tax is charged as penalty
- Interest at the prevailing Central Bank of Nigeria (CBN) rate is applied on the outstanding amount until payment is made
Example: If CIT due is ₦8 million and is not paid on time:
Penalty = ₦800,000
Interest = (assume 15%) = ₦1.2 million annually if unpaid for 1 year
3. Failure to File Audited Financial Statements
This may result in:
- Rejection of tax returns by FIRS
- Potential audit and enforcement actions
- Inability to obtain a Tax Clearance Certificate (TCC)
4. False or Misleading Information
Providing incorrect or fraudulent information to reduce tax liability can result in:
- Severe financial penalties
- Legal prosecution under the FIRS Establishment Act
- Disqualification from government contracts or grants
5. Failure to Withhold or Remit WHT (Related to CIT)
If a company fails to withhold or remit Withholding Tax (e.g., on vendor payments):
- 10% penalty on the amount due
- Interest at the prevailing CBN rate
6. Failure to Obtain TIN or Register for CIT
Failure to register a company for tax purposes or obtain a Tax Identification Number (TIN) can:
- Lead to fines
- Result in account restrictions or denial of government approvals
- Prevent access to credit facilities requiring tax compliance
CIT Enforcement Measures
- Freezing of corporate bank accounts via court orders
- Audit investigations and back-duty assessments
- Public listing as a non-compliant taxpayer
- Seizure of assets in extreme cases
How to Avoid CIT Penalties
- File CIT returns within 6 months after your accounting year ends
- Keep clean and up-to-date books
- Engage a licensed tax consultant or accountant
- Use the FIRS TaxPro Max platform for real-time tax filing and tracking
- Apply for extensions (if needed) before deadlines using valid justification
- Use Flex Finance to manage business spend for effective expense categorization to stay audit-ready always.
What is PAYE?
Pay As You Earn (PAYE) is a system of tax collection on individual income, where employers deduct personal income tax (PIT) from employee salaries at source and remit it to the relevant State Internal Revenue Service (SIRS).
This ensures employees pay their taxes monthly, and it applies to both public and private sector workers.
Employer’s Responsibility in PAYE Deductions
Employers are agents of tax collection and have legal obligations to:
- Deduct tax monthly from employee gross salaries
- Remit deductions to the relevant SIRS (based on business or employee location)
- File monthly and annual PAYE returns (Form H1)
- Register each employee with the SIRS
- Issue tax deduction cards and annual tax returns (Form H2)
PAYE Tax Bands and Calculation in Nigeria
Nigeria uses a graduated tax rate system based on annual income, as follows:
How to File PAYE Returns with SIRS
Monthly Returns (Form H1)
- Submitted on or before the 10th day of the following month
- Contains: employee details, gross income, tax deducted, reliefs applied
Annual Returns (Form H2)
- Filed before 31st January of the following year
- Summarizes all taxes remitted in the previous year
Platforms:
- Most states (e.g., Lagos, Rivers, Ogun) now use online e-filing portals
- Employers must register for an employer code with the respective SIRS
Timeline for Remitting PAYE Deductions
- PAYE deductions must be remitted on or before the 10th day of every month
- Deductions are remitted to the state of residence of the employee, not necessarily where the employer is located
Employee Tax Reliefs and Deductions
Reliefs reduce the taxable income and include:
- Consolidated Relief Allowance (CRA)
- 20% of gross income + ₦200,000
- 20% of gross income + ₦200,000
- Pension Contributions (minimum 8% of gross salary)
- National Housing Fund (NHF) – 2.5% (if enrolled)
- Life Assurance Premium
- Gratuities and certain non-taxable allowances like estacode, transport (if not in cash)
For Example: Monthly PAYE Calculation for a Mid-Level Employee
Scenario:
- Monthly Gross Salary: ₦500,000
- Pension: 8% (₦40,000)
- NHF: 2.5% (₦12,500)
- No other deductions
Step 1: Annualize Income
₦500,000 × 12 = ₦6,000,000
Step 2: Apply CRA
- CRA = ₦200,000 + 20% of ₦6,000,000 = ₦1,400,000
- Pension = ₦40,000 × 12 = ₦480,000
- NHF = ₦12,500 × 12 = ₦150,000
Total Reliefs = ₦1,400,000 + ₦480,000 + ₦150,000 = ₦2,030,000
Step 3: Taxable Income
₦6,000,000 – ₦2,030,000 = ₦3,970,000
Step 4: Apply Tax Bands
Total Annual PAYE = ₦744,800
Monthly PAYE = ₦744,800 ÷ 12 ≈ ₦62,067
Penalties for Late PAYE Remittance
What is WHT?
Withholding Tax (WHT) is an advance payment of income tax deducted at source from qualifying payments like rent, dividends, professional fees, and contract payments.
Rather than wait for the final income tax assessment, the payer deducts WHT on behalf of the government and remits it to the appropriate tax authority, Federal Inland Revenue Service (FIRS) or the State Internal Revenue Service (SIRS).
WHT helps reduce tax evasion and improves early tax collection efficiency.
WHT Rates Based on Nature of Transaction
Example: A company that pays ₦1,000,000 for a contractor’s service must deduct 5% (₦50,000) as WHT and remit it to FIRS/SIRS.
When and How WHT is Deducted
- WHT is deducted at the time of payment or credit, whichever comes first.
- The payer is responsible for deducting and remitting the tax.
- The payee receives the balance (net of WHT), and the deduction is credited to their tax account.
Example:
A company hires a marketing consultant and agrees on a ₦500,000 fee.
- WHT to deduct: 10% of ₦500,000 = ₦50,000
- Consultant receives: ₦450,000
- Company remits ₦50,000 to FIRS
WHT Filing and Payment Timeline
WHT must be remitted within 21 days after the month of deduction.
Non-compliance attracts a penalty of 10% of the amount not withheld or remitted, plus interest at the prevailing Central Bank of Nigeria (CBN) rate.
WHT Credit Notes and Tax Offset
After remittance, the tax authority issues a Withholding Tax Credit Note (WHTCN) in the name of the vendor (the tax beneficiary). This credit can be:
- Used to offset future tax liabilities (e.g., CIT, PIT)
- Presented during tax audits or returns filing as proof of advance tax payment
Example Use Case:
- ABC Ltd has ₦5 million in CIT payable.
- They present ₦1 million worth of WHT credit notes.
- Final payable CIT = ₦4 million
Important: Vendors must ensure the credit note is in their TIN and name, or it won’t be accepted.
Common WHT Errors and How to Avoid Them
Final Tips
- Always ask vendors for valid TIN before payment
- Use FIRS TaxPro Max or your state tax portal for e-remittance and credit note downloads
- Match WHT filings with bank payment evidence
- Reconcile WHT monthly to avoid backlog or lost credits
- Use Flex Finance to manage business spend for effective expense categorization to stay audit-ready always.
Tax Compliance Best Practices for Nigerian Businesses
Maintaining tax compliance is not only a legal requirement but also a strategic move for business growth, access to funding, and participation in government contracts. Below are key practices every Nigerian business should adopt to ensure they remain on the right side of tax laws:
Keeping Accurate Records
Maintaining complete and accurate financial records is foundational for tax compliance.

- Annual returns – by 6 months after financial year-end
- PAYE – by 10th of each month
- Use task management tools (e.g., Trello, Asana, Outlook reminders) for automatic alerts.
Pro Tip: Assign a dedicated compliance officer or team lead to oversee timely filings.
Leveraging Government Tax Amnesty Programs
The Nigerian government occasionally offers tax amnesty schemes to ease the burden on businesses and encourage voluntary compliance:
- VAIDS (Voluntary Assets and Income Declaration Scheme)
- PIT and VAT waiver programs during economic crises (e.g., COVID-19 relief)
- Waiver of penalties and interest for businesses that self-disclose liabilities
