Many people ask questions like:

• How do I calculate tax for my small business in Nigeria?

This guide explains how to calculate taxes for small businesses in Nigeria.

What Is A Small Business In Nigeria?

In Nigeria, a small business is generally classified based on annual turnover (total income before expenses).

According to Nigerian tax regulations:

• A small business is one with an annual turnover of ₦25 million or less
• A medium business earns between ₦25 million and ₦100 million
• A large business earns above ₦100 million

This classification is important because small businesses enjoy certain tax reliefs, especially under Company Income Tax rules.

Why Small Businesses Must Pay Taxes

Paying taxes is not just a legal requirement; it also comes with benefits:

• It keeps your business legally compliant
• It helps you avoid penalties and fines
• improves your chances of accessing loans and grants
• It builds business credibility
• IIt supports national development (roads, schools, healthcare)

Understanding how taxes are calculated helps you plan better and avoid surprises.

Types Of Small Businesses In Nigeria

Your tax obligations depend on how your business is registered:

Sole Proprietorship

• Owned by one person
• Business income is treated as personal income
• Taxed under Personal Income Tax (PIT)

Partnership

• Owned by two or more people
• Partners pay tax individually on their share of profit
• Taxed under Personal Income Tax

Limited Liability Company (Ltd)

• Registered with the Corporate Affairs Commission (CAC)
• Taxed separately from the owners
• Pays Company Income Tax (CIT) and other applicable taxes

Main Taxes Small Businesses Pay In Nigeria

Small businesses do not pay all taxes at once. You only pay what applies to your business structure and activities.

Personal Income Tax (PIT)

This applies to:

• Sole proprietors
• Freelancers
• Partnerships

Personal Income Tax is charged on profit, not total sales.

How PIT Is Calculated

• Calculate your total annual income
• Subtract allowable expenses (rent, transport, salaries, supplies, etc.)
• Apply reliefs and allowances
• Apply the graduated tax rates

Current PIT Tax Bands (Simplified)

• First ₦300,000 – 7%
• Next ₦300,000 – 11%
• Next ₦500,000 – 15%
• Next ₦500,000 – 19%
• Next ₦1,600,000 – 21%
• Above that – 24%

Example:

If your annual profit is ₦1,200,000:

• You don’t pay a flat rate
• You pay different percentages on different portions of your income
• This reduces your total tax burden

Company Income Tax (CIT)

This applies to registered limited liability companies.

Good news for small companies:

• If your company turnover is ₦25 million or less, CIT rate is 0%

That means:

• You still file tax returns
• But you don’t pay Company Income Tax

This policy was created to encourage small business growth.

Value Added Tax (VAT)

VAT applies to most goods and services in Nigeria.

VAT Rate

• 7.5%

Who Pays VAT?

• The customer pays VAT
• The business collects and remits VAT to FIRS

VAT Calculation Example:

If you sell goods worth ₦100,000:

• VAT = 7.5% of ₦100,000 = ₦7,500
• Customer pays ₦107,500
• You remit ₦7,500 to FIRS

Note: Some basic items like medical services and basic food items are VAT-exempt.

Withholding Tax (WHT)

Withholding tax is an advance tax payment.

It applies when:

• You provide services
• You earn commissions
• You receive professional fees

Rates vary from 5% to 10%, depending on the transaction.

The tax deducted:

• Is not extra tax
• Is later credited against your final tax bill

Pay As You Earn (PAYE)

If you employ staff:

• You must deduct PAYE from their salaries
• You remit it to the State Internal Revenue Service

PAYE is calculated using graduated tax bands similar to Personal Income Tax.
