Running an SME in Nigeria is not for the faint-hearted. Beyond customers, suppliers, staff, and cash flow, there is one area that quietly determines whether a business survives long-term or collapses under pressure — tax compliance.
Many Nigerian SMEs fail not because they are unprofitable, but because they misunderstand their tax obligations. Some pay more tax than required. Others ignore filing completely until penalties pile up. A few only realize their mistakes when their bank account is frozen or their office is sealed.
This guide explains SME tax obligations in Nigeria in a way that is clear, practical, and realistic. No legal jargon. No fear-mongering. Just what actually applies to small businesses in 2026, why it matters, and how to handle it properly.
Understanding What “SME” Means Under Nigerian Tax Law
In Nigeria, taxes are not based on how many staff you have or how popular your business is. They are largely based on annual turnover.
Under the Companies Income Tax Act (CITA) as amended by recent Finance Acts, businesses are classified as follows:
- Small companies: ₦25 million turnover or less
- Medium companies: Above ₦25 million but below ₦100 million
- Large companies: ₦100 million and above
This classification is critical because it determines:
- Whether you pay Company Income Tax
- The tax rate that applies
- Whether certain levies apply to you

Why SME Tax Compliance Is No Longer Optional
Ten years ago, many small businesses operated informally without serious consequences. That era is ending.
Today:
- Banks request tax clearance certificates
- Investors demand proof of compliance
- Government agencies share data
- FIRS and State IRS systems are more digital
Tax compliance now directly affects:
- Access to loans and grants
- Eligibility for government contracts
- Business reputation and valuation
- Long-term survival
Tax is no longer just a legal issue — it is a business strategy issue.
Overview of SME Tax Obligations in Nigeria
Depending on your business structure and size, an SME may be required to comply with some or all of the following:
- Company Income Tax (CIT)
- Value Added Tax (VAT)
- Withholding Tax (WHT)
- Pay As You Earn (PAYE)
- Personal Income Tax (for sole proprietors)
- Education / Development Levies (where applicable)
Let’s break each one down clearly.
Company Income Tax (CIT): What SMEs Must Know
What CIT Is
Company Income Tax is charged on the profits of incorporated businesses in Nigeria.
Profit here means:
Revenue – allowable business expenses
CIT Rates for SMEs (2026)
- Small companies (≤ ₦25m turnover): 0%
- Medium companies (₦25m–₦100m): 20%
- Large companies: 30%

Critical Insight Most SMEs Miss
Even if your company pays 0% CIT, you are still legally required to file annual tax returns.
Failure to file:
- Triggers penalties
- Can flag your business for audit
- Affects your tax clearance status
Filing Deadline
- Within 6 months after financial year-end, or
- 18 months after incorporation for new companies

Value Added Tax (VAT): The Most Enforced SME Tax
VAT is one of the most actively monitored taxes in Nigeria.
VAT Rate
7.5%
Who Must Register for VAT?
If your SME’s turnover exceeds ₦25 million annually, you must:
- Register for VAT
- Charge VAT on taxable goods/services
- Collect VAT from customers
- Remit VAT monthly to FIRS
VAT Filing Deadline
On or before the 21st day of the following month
VAT Reality Check
VAT is not your money.
It belongs to the government.
Your business only acts as a collection agent.
Misusing VAT funds is one of the fastest ways SMEs run into serious trouble.

Withholding Tax (WHT): Often Confusing, Often Mismanaged
Withholding Tax is not an extra tax. It is a prepayment of income tax.
When WHT Applies
When your SME pays for:
- Rent
- Consultancy
- Professional services
- Contracts
You may be required to deduct tax at source and remit it to the tax authority.
Typical Rates
- Rent: 10%
- Consultancy: 10%
- Contracts: 5%
Why WHT Matters
If you fail to deduct or remit WHT:
- The tax authority holds you responsible
- Penalties and interest apply

If your business employs staff, PAYE compliance is mandatory.
What PAYE Involves
- Deducting income tax from employee salaries
- Remitting deductions to the State Internal Revenue Service
PAYE Deadline
On or before the 10th day of the following month
PAYE issues are one of the most common reasons SMEs face enforcement actions at the state level.

- Business profits are taxed under Personal Income Tax
This applies to:
- Traders
- Freelancers
- Consultants
- Partnerships
Tax is paid to the State Internal Revenue Service, not FIRS.
