You'll have heard two things this year. One is that small businesses no longer pay tax. The other is that everyone now has to register and file. Both are passed around with confidence, and both leave out the part that matters to a shop owner.

This is a plain summary of how the rules apply to a small shop. It is general information, checked against PwC's published tax summaries for Nigeria, which were last reviewed on 29 May 2026. It isn't tax advice. Tax depends on your own facts, the rules are new, and you should confirm your position with an accountant or your state revenue office.

The first question: what kind of business are you?

Most of the confusion comes from skipping this.

A registered company. Your business is a limited company, with "Ltd" in its name. The company is a separate person in law and it pays companies income tax.

A business name, or not registered at all. You registered a business name with the CAC, or you simply trade. In law, the business is you. There's no separate company. You pay personal income tax on what the business earns.

Most provision stores, boutiques and phone shops are in the second group. And the well-known "0% for small companies" rule belongs to the first.

If you are a company

PwC's summary of corporate income tax describes small companies as those with annual gross turnover of ₦100 million or less and total fixed assets not exceeding ₦250 million. For these, the companies income tax rate is 0%. It also says the 4% Development Levy applies to companies subject to tax, except small companies and non-resident companies.

So a small limited company that meets both tests pays no companies income tax. That isn't the same as having no tax duties. See "What exemption doesn't mean" below.

If you are a business name or an individual trader

You're taxed as a person, on your profit. Not on your sales.

PwC's summary of personal income tax lists these bands for 2026:

Slice of yearly taxable incomeRate
First ₦800,0000%
Next ₦2,200,00015%
Next ₦9,000,00018%
Next ₦13,000,00021%
Next ₦25,000,00023%
Above ₦50,000,00025%

Each rate applies only to its own slice.

Here is a simple illustration that ignores any reliefs or deductions you may be entitled to. Say your shop's profit for the year, after all business expenses, is ₦3,000,000. The first ₦800,000 is taxed at 0%. The remaining ₦2,200,000 is taxed at 15%, which is ₦330,000. That's ₦330,000 on ₦3 million, or 11% overall.

If your profit for the year is ₦800,000 or less, the tax on it under these bands is nil.

Personal income tax is generally handled by the revenue service of the state where you live.

VAT

VAT is a tax on sales that a business collects from customers and passes on. PwC's summary of other taxes gives the standard rate as 7.5% and says small businesses are exempt from collecting it. It also lists zero-rated items, including basic food items on a specific list, medical and pharmaceutical products, and books and educational materials.

We haven't stated the turnover threshold for the small business exemption here, because the figures in circulation differ and we couldn't confirm one from a source we'd rely on. Ask your accountant which figure applies to you, particularly if your yearly sales run into tens of millions.

What exemption doesn't mean

This is where people get caught.

It may not mean you can ignore registration and filing. Being charged at 0%, or falling under a threshold, is different from being outside the system. You may still be expected to hold a tax identification number and to file returns showing that you qualify. Confirm what applies to you.

It doesn't cover your staff. If you employ people, there are rules on deducting tax from salaries above the exempt level and remitting it.

It doesn't cover state and local charges. Business premises registration, signage fees, local government permits and market levies are separate from income tax and VAT.

It doesn't last if you grow. The tests are based on turnover and assets. Cross them and the position changes.

Why your records matter here

Every figure above depends on a number you have to be able to show: your turnover, or your profit.

A trader with no records can't prove their profit was ₦700,000 and not ₦7 million. When there are no records, an assessment may be made on estimates, and estimates rarely favour you.

So the practical step for a small shop isn't complicated. Keep:

With those four you can work out your profit, as shown in how to calculate profit and loss for a shop, and you can show how you got there.

What to do this month

  1. Find out which you are: a company or a business name. Your CAC certificate says.
  2. Work out last year's turnover and profit as best you can.
  3. Take those two figures to an accountant or your state revenue office and ask three questions. What do I need to register for? What do I need to file, and when? What, if anything, do I owe?

An hour with an accountant once a year costs less than one penalty, and far less than one argument with no paperwork behind you.
