How to Pay Tax for Small Business in Nigeria
Why Tax Matters for Your Business
Paying taxes is more than just a legal obligation it’s a key part of running a legitimate, sustainable business in Nigeria. Compliance helps you:
- Avoid penalties and legal issues
- Build credibility with clients and banks
- Qualify for government contracts and opportunities
- Access financing or grants that require tax clearance
Nigeria’s tax system operates on a self-assessment basis, meaning you assess, file, and pay most taxes yourself through the appropriate system and authorities.
Register Your Business for Tax
Before you can pay any tax, you must register your business and obtain a Tax Identification Number (TIN):
Step-by-Step
- Register your business with CAC (Corporate Affairs Commission) whether as a sole proprietor, partnership, or limited company.
- Apply for your TIN from the Federal Inland Revenue Service (FIRS) or your State Internal Revenue Service (if you operate as a sole proprietor).
The TIN is compulsory for all tax filings, opening business bank accounts, and official business operations.
Note: Without a TIN, you cannot legally file returns or pay taxes.
Know the Taxes Your Business May Pay
Understanding which taxes apply to you depends on your business type, revenue level, and workforce. Below are the common ones.
- Company Income Tax (CIT)
Charged on profit of companies incorporated in Nigeria.
Small businesses with turnover under ₦25 million are usually exempt from CIT.
Typical CIT rates (approx.):
- Business Size
- Turnover
- CIT Rate
Small < ₦25m ( 0%)
Medium <₦25m– ₦100m ( 20% )
Large > ₦100m ( 30% )
CIT returns are filed annually and must be submitted within six months after the company’s financial year end.
- Personal Income Tax (PIT)
If your business is sole proprietorship or partnership, your business income is taxed as personal income.
Tax rates are graduated meaning higher income attracts higher tax.
Businesses with employees must deduct PAYE (Pay-As-You-Earn) from salaries and remit monthly to the State IRS.
- Value Added Tax (VAT)
VAT is a consumption tax charged on the sale of goods and services.
Current VAT rate in Nigeria: 7.5%.
You collect VAT from customers and remit to FIRS monthly, usually by the 21st day of the next month.
If your annual turnover is below a certain threshold (often ₦25–50 million), you may file NIL returns until you exceed it.
- Withholding Tax (WHT)
Withholding Tax is deducted at the source on certain payments, such as:
- Rent
- Professional and contractor fees
- Consultancy and service charges
Rates vary (commonly 5%–10%) and must be remitted to tax authorities within a specified period (often within 21 days).
- Other Taxes and Levies
Depending on your activity and structure, you may also encounter:
- Business Premises Tax – a state levy for operating a business property.
- Capital Gains Tax — on gains from selling business assets.
- Stamp Duties — on legal documents and agreements.
- Education Tax (TETFund) — a levy on assessable profits for companies subject to CIT.
Filing Frequency & Deadlines
Tax Type. Filing Frequency. Due Date
CIT. Annual. Within 6 months after financial year end
VAT. Monthly. 21st of following month
PAYE. Monthly. Usually 10th of following month
