1. The Two Tax Masters: Federal vs. State
Nigeria operates a dual-tier tax system for businesses. You must understand which government agency handles specific tax types to avoid paying the wrong authority.
The Federal Level: Federal Inland Revenue Service (FIRS)
The FIRS is responsible for collecting taxes that go into the federal account. They govern all incorporated entities (companies with Limited Liability/LTD status) and specific consumption taxes.
The State Level: State Internal Revenue Services (SIRS)
Each of the 36 states has its own tax authority (e.g., LIRS in Lagos, IRS in Abuja, FIRS equivalents in other states). They collect taxes from individuals, registered Business Names (Sole Proprietorships/Partnerships), and employee personal income taxes.
2. Key Taxes Every Nigerian SME Must Know
Your tax obligations depend heavily on how your business is legally structured with the Corporate Affairs Commission (CAC) and your annual revenue volume.
Company Income Tax (CIT)
Who Pays It: Only registered Limited Liability Companies (LTD). Simple "Business Names" do not pay CIT.
The Small Business Advantage: Thanks to the Finance Act, small companies with an annual turnover of less than ₦25 million are completely exempt from paying CIT.
The Catch: Even if your turnover is zero or under ₦25 million, you are still legally required to file your tax returns every year with the FIRS to maintain an "Active" tax status. Medium companies (turnover between ₦25 million and ₦100 million) pay a reduced CIT rate of 20%.
Personal Income Tax (PIT) & Direct Assessment
Who Pays It: Sole proprietors, partners in a business name, and individual freelancers.
How It Works: Because a Business Name is legally seen as an extension of the owner, the profit of the business is taxed as your personal income. This is assessed annually by your State Internal Revenue Service (SIRS) based on your filed self-assessment returns.
Value Added Tax (VAT)
The Current Landscape: VAT is a 7.5% consumption tax charged on the sale of goods and services.
The Threshold Rule: Small businesses with an annual turnover below ₦25 million are legally exempt from registering for, charging, or remitting VAT.
Important Exception: If you operate in the oil and gas sector, or if you are a contractor bidding for government contracts or doing business with large corporate entities, you must be VAT-compliant regardless of your annual revenue.
Pay-As-You-Earn (PAYE)
Who Pays It: Any business (whether LTD or Business Name) that has paid employees earning above the minimum taxable threshold.
Your Role as an Employer: You are legally mandated to deduct this tax directly from your employees' monthly salaries and remit it to the State Internal Revenue Service where the employee resides by the 10th day of the following month.
3. Local Government Levies and the Multi-Taxation Trap
Beyond federal and state agencies, your local government area (LGA) council officials will periodically visit your physical storefront or office to collect localized rates.
Legitimate LGA Charges: These typically include tenement rates, shop branded signage/billboard permits, environmental sanitation fees, and waste disposal levies.
How to Avoid Scams: Never pay cash to any field official claiming to be an LGA agent. Insist on a formal demand notice showing an official government bank account number or a verified digital payment platform link. Pay online or via bank transfer, and collect an official government-stamped receipt.
4. Step-by-Step Compliance Checklist for SMEs
Secure Your TIN: Ensure you have your Tax Identification Number. For new businesses, this is automatically generated alongside your CAC registration document.
Separate Your Bank Accounts: Never mix personal cash flow with business revenue. It makes auditing your true financial turnover incredibly difficult and can lead to over-taxation during audits.
Use TaxTech Portals: Utilize modern online tax filing platforms. The FIRS uses the TaxPro-Max Portal for seamless remote filing and automated assessments. States like Lagos utilize the LIRS eTax Portal for quick PAYE and direct assessment processing.
File on Time: Keep track of your calendar deadlines. CIT returns for companies must be filed within six months after the end of the business financial year. Annual PIT returns for individuals and business names must be submitted to the state by March 31st of every calendar year.
