Small Business Tax in Nigeria (2026): PAYE, CIT, VAT Explained

If you run a small business in Nigeria, tax becomes confusing the moment you mix three very different things together:

PAYE on salaries
CIT on company profits
VAT on taxable supplies

And once you start paying contractors, consultants, landlords, or similar counterparties, a fourth issue can enter the picture: withholding tax. If that is the part you need explained, read What Is Withholding Tax in Nigeria?.

That confusion causes real problems. Founders overpay, under-remit, misread cash flow, or assume a company with a low tax rate has no compliance work left to do.

This guide is designed to fix that.

Quick answer

Use this simple model:

| Tax | What it applies to | The question it answers | | --- | --- | --- | | PAYE | Employee salaries | What tax should be deducted from staff pay? | | CIT | Company profits | What tax is due on the company's taxable profit? | | VAT | Taxable supplies | What VAT should be charged, collected, and remitted where applicable? |

If you remember only one thing, remember this:

PAYE is not CIT. CIT is not VAT.

What changed under the 2026 framework

From January 1, 2026, the Nigeria Tax Act and Nigeria Tax Administration Act reshaped the framework many founders rely on.

For small-business owners, the practical headlines are:

PAYE now sits inside the new 2026 personal-tax framework
qualifying small companies may fall into a 0% company income tax rate
companies outside the small-company category may also need to factor in the development levy
VAT remains a separate transaction-tax workflow with its own collection and invoicing obligations

That does not make tax simpler by magic. It means you need a cleaner mental model.

Why founders get this wrong

Many founders do one or more of these:

Calculate PAYE like it is company tax
Assume VAT collected is profit
Think "small company" means no tax work at all
Delay records because they plan to sort it later
Mix owner personal tax with company obligations

That leads to:

Under-remittance
Overpayment
Avoidable penalties
Stressful year-end cleanup

The fix starts with separating the taxes clearly.

Before any of that works cleanly in practice, the business should also have the correct taxpayer registration record in place. If you need the registration layer first, start with Tax Identification Number (TIN) in Nigeria (2026): What It Is, Who Needs It, and Where to Start.

1) PAYE: employee income tax, not company profit tax

If you have staff and you pay salaries, PAYE is part of your payroll responsibility.

What PAYE means in practice

PAYE is deducted from employee salaries and remitted to the relevant tax authority (typically the relevant State Internal Revenue Service for most individuals, with some exceptions).

Under the 2026 framework, PAYE is still calculated on chargeable income, not gross salary alone. That means deductions and reliefs can change the outcome.

Common payroll mistakes

Most errors happen at calculation stage:

Using the wrong taxable base
Leaving out eligible deductions
Treating reliefs like cash payouts
Doing monthly-only estimates without proper annualization

The PAYE flow in plain English

Start with gross annual income
Subtract eligible deductions/reliefs to get chargeable income
Apply 2026 progressive PAYE bands
If input is monthly, annualize first (monthly x 12), calculate annually, then show monthly view

Deductions to include in payroll estimation

TaxCalc supports deductions/reliefs such as:

Pension
NHF
NHIS / approved health insurance
Life insurance / deferred annuity
Owner-occupied home loan interest
Rent relief (subject to TaxCalc cap logic)

If payroll estimates are wrong at source, PAYE remittance gets harder later.

2) CIT: tax on company profits

This is the tax many founders accidentally confuse with payroll.

PAYE vs CIT (important)

PAYE is employee salary tax you deduct/remit
CIT is company tax on taxable profits

So even if payroll is perfect, your company can still have CIT obligations.

What is a small company under the current Act

Under the Nigeria Tax Act 2025, a small company is generally a company with:

Gross turnover of NGN 50,000,000 or less per annum, and
Total fixed assets not exceeding NGN 250,000,000

The law also notes that companies providing professional services are not classified as small companies for that definition.

The CIT rates founders should know

The Nigeria Tax Act states:

Small company: 0%
Any other company: 30% (from commencement of the Act)

It also introduces an effective tax rate rule (15%) for certain large entities (including some MNE-group constituent entities and very high turnover thresholds), which usually affects larger organizations rather than typical SMEs.

Practical mistake to avoid

Many owners hear "0% CIT" and conclude "I do not need records."

That is the wrong move.

Even where tax payable is low or nil, you still need clean documentation, bookkeeping, and filing readiness.

3) VAT: collected on taxable supplies, not "extra profit"

VAT is where many businesses misread cash flow.

The basic idea

When you make taxable supplies, VAT is generally charged and collected/remitted under the rules. The Nigeria Tax Act sets VAT on taxable supplies at 7.5% (subject to exemptions and zero-rating rules).

Why founders get confused

A frequent mistake is treating VAT collected like extra revenue.

It is not.

VAT is typically collected on behalf of the tax system (subject to input/output VAT mechanics and applicable rules). So:

Revenue is not the same as VAT collected
Profit is not the same as VAT collected
Cash in bank is not automatically spendable cash

Not all supplies are treated the same

The Act includes:

Exempt items/supplies (in relevant schedules)
Zero-rated taxable supplies (for certain categories)

The right question is not only "Do I charge VAT?" but "Is this supply taxable, exempt, or zero-rated under the law?"

VAT documentation still matters

The Act includes VAT invoice requirements (including invoice numbering and showing VAT charged/rate), and states that taxable persons making taxable supplies should collect VAT at the statutory rate.

Clean records from day one reduce compliance friction later.

The simple mental model: PAYE vs CIT vs VAT

Use this:

PAYE -> employee salary tax (payroll process)
CIT -> company profit tax (accounting and tax computation)
VAT -> transaction tax on taxable supplies (sales/invoicing/remittance)

Different taxes, different calculations, different workflows.

Once you separate them, compliance gets easier.

A better founder checklist for 2026

Separate payroll from company finance.
Stop estimating from memory.
Know your tax lane before filing season.
Keep clean reports you can revisit.

1) Separate payroll from company finance

Do not run employee tax from random notes or chat messages. Use a proper payroll flow.

2) Stop estimating from memory

Use records for:

Payroll breakdowns
Invoices
Expense categories
Deduction support documents

3) Know your lane before filing season

Ask:

Do I have employees? -> PAYE matters now
Am I running a registered company? -> CIT matters
Do I make taxable supplies? -> VAT may apply

4) Keep reports you can return to

When inputs are not saved, every correction becomes a full rebuild.

The short version

Most small-business tax confusion comes from treating different taxes like one problem.

They are not one problem.

PAYE is payroll
CIT is profit tax
VAT is supply tax

Once you separate the workflow, the decisions get easier, the records improve, and the risk of avoidable errors drops.

Frequently asked questions about small business tax in Nigeria (2026)

What is the difference between PAYE, CIT, and VAT?

PAYE is employee salary tax, CIT is company tax on profits, and VAT is transaction tax on taxable supplies. They are different obligations with different workflows.

If my company qualifies as a small company, can I ignore compliance?

No. Even where CIT payable is low or nil, you still need proper records, bookkeeping, and filing readiness.

Is VAT collected by my business treated as profit?

No. VAT collected is generally not profit; it is collected/remitted under VAT rules, subject to applicable mechanics and treatment.

Can I use TaxCalc without sign-up?

Yes. You can run quick PAYE checks on Free without sign-up.

Final word

For many Nigerian small businesses, the real problem is not the existence of PAYE, CIT, and VAT. It is the habit of mixing them together until every tax task feels harder than it should.

Separate the taxes. Use the right numbers. Keep the records.

That is what good compliance looks like in practice.
