Audit Exemptions for Small Companies in Nigeria: Who Qualifies in 2026?

Big changes arrived in 2026.

If you own a small business in Nigeria, you need to pay attention. The Nigeria Tax Act 2025 and CAMA 2020 together have created something unprecedented.

Zero percent corporate income tax for qualifying small companies. Plus audit exemptions that slash compliance costs.

But who actually qualifies? And how do you claim these benefits without making costly mistakes?

Let me break it down for you.

What is a statutory audit anyway?

Before we talk about exemptions, let us understand what an audit actually is.

A statutory audit is a legal requirement for most companies. An independent auditor checks your financial statements. They give an opinion on whether your numbers tell the truth.

Think of it as a financial health check. Someone outside your business verifies that you are not cooking the books.

For large companies, this makes perfect sense. For small businesses? It has always been a crushing burden.

The old problem for small Nigerian companies

Let me show you the math from before 2025.

A small trading company in Lagos with ₦80 million turnover and ₦10 million profit used to face this:

• Audit cost: ₦1,000,000

• Corporate income tax at 30%: ₦3,000,000

• Total burden: ₦4,000,000

That is 40% of their profit gone to compliance and tax.

No wonder so many businesses stayed informal. Why register when the government takes nearly half your profit?

The 2025 reforms fixed this. Let me explain how.

Nigeria Tax Act 2025: Revolutionary changes for small companies

The Nigeria Tax Act 2025 is not a small tweak. It is a complete overhaul for small businesses.

Here is the headline.

Qualifying small companies now pay 0% corporate income tax on their profits. Not a tax holiday. Not a temporary incentive. Permanent zero percent.

But you must meet specific criteria. And there is a major exclusion you need to know about.

As a tax advisory and tax consulting service provider , Stonehill Research helps small companies navigate these new provisions.

Who qualifies for 0% tax under the Tax Act 2025?

You need to pass two tests. Both are mandatory.

Test 1: Gross turnover of ₦100 million or less per year

This means all your operating revenue. Sales, services, commissions. Everything from your core business activities.

Investment income like interest on savings does not count toward this limit.

Test 2: Total fixed assets not exceeding ₦250 million

Fixed assets are things like land, buildings, machinery, vehicles, furniture, and computers. We use the gross value before depreciation.

You must meet BOTH tests. Fall short on either one and you lose the 0% rate.

Important note: According to legal experts, there are two versions of the Tax Act currently in circulation. The FIRS version set the small company threshold at ₦50 million, while the presidentially signed Final Approved Copy raises it to ₦100 million. You should follow the signed version. [1]

The professional services exclusion that catches many business owners

Here is where people get confused.

Professional services businesses are completely excluded from the 0% tax rate. It does not matter how small your turnover or assets are.

What counts as professional services?

Law firms. Accounting and auditing firms. Medical practices and private hospitals. Architectural and engineering consulting. Management and IT consulting. Advertising agencies. Financial advisory services. Private schools and training centers.

If you run any of these, you pay the regular corporate income tax rate (reduced from 30% to 25% for large companies under the new Act).

But wait. There is good news. You may still qualify for audit exemption under CAMA 2020. The professional services exclusion only applies to tax, not to audit relief.

Examples: Who gets the 0% tax rate?

Qualifying example: Lagos retail store

• Turnover: ₦85 million ✓

• Fixed assets: ₦120 million ✓

• Business type: Retail trading (not professional services) ✓

Result: Qualifies for 0% CIT. Saves millions in taxes.

Non-qualifying example: Abuja law firm

• Turnover: ₦60 million ✓

• Fixed assets: ₦30 million ✓

• Business type: Legal services (professional services) ✗

Result: Does NOT qualify for 0% tax. Pays regular CIT.

Non-qualifying example: Manufacturing company

• Turnover: ₦95 million ✓

• Fixed assets: ₦300 million ✗

• Business type: Manufacturing (not professional services) ✓

Result: Does NOT qualify. Fixed assets too high. [2]

CAMA 2020 audit exemption: A separate opportunity

Now let us talk about audit exemption. This comes from CAMA 2020, not the Tax Act.

The rules are different here. And the good news? Professional services are NOT excluded from audit relief.

Under Section 394 of CAMA 2020, to qualify for audit exemption, you need to meet at least two of these three conditions:

1. Annual turnover of ₦120 million or less

2. Net assets of ₦60 million or less

3. Average of 50 employees or fewer

Net assets means total assets minus total liabilities. Or simply share capital plus reserves.

Note: CAMA 2020 also requires that the company has no foreign members, government members, or government corporations, and that at least 51% of equity share capital is held by directors. [3]

Examples of who gets audit exemption

Example 1: Port Harcourt retail company

• Turnover: ₦110 million ✓

• Net assets: ₦48 million ✓

• Employees: 65 ✗

Meets 2 of 3. Qualifies for audit exemption.

Example 2: Abuja law firm (professional services)

• Turnover: ₦75 million ✓

• Net assets: ₦25 million ✓

• Employees: 12 ✓

Meets all 3. Qualifies for audit exemption even though they do not get tax exemption.

Example 3: Lagos manufacturing company

• Turnover: ₦150 million ✗

• Net assets: ₦85 million ✗

• Employees: 45 ✓

Meets only 1 of 3. Does NOT qualify for audit exemption.

Companies that cannot claim audit exemption

Even if you meet the criteria, some companies are completely barred from audit exemption.

Public companies. Banks and financial institutions. Insurance companies. Pension fund administrators. Oil, gas, and mining companies. Government-owned entities. Subsidiaries of any of the above.

If you fall into these categories, you must have a statutory audit regardless of your size.

Our debt collection and recovery services help businesses maintain financial integrity while remaining compliant.

The perfect scenario: Getting both exemptions

The biggest winners are companies that qualify for both 0% tax and audit exemption.

Let me show you a real example.

A small trading company in Lagos:

• Turnover: ₦85 million

• Fixed assets: ₦120 million

• Net assets: ₦45 million

• Employees: 35

• Not a professional service

Tax exemption: YES (turnover under ₦100M, assets under ₦250M)
Audit exemption: YES (meets all 3 CAMA criteria)

Annual savings:

• Tax saved (₦10M profit at 0% vs 30%): ₦3,000,000

• Audit cost saved: ₦400,000

• Total: ₦3,400,000

Their compliance cost under the new regime? About ₦870,000 for bookkeeping and filings.

Net benefit: ₦2,530,000 per year. That is real money for a small business.

Critical things you must know

Filing is still mandatory

Zero percent tax does not mean zero paperwork. You must file your annual self-assessment return. Failure to file attracts penalties even if you owe no tax.

Monitor your thresholds constantly

If you exceed the turnover or asset limits at any point during the year, you likely lose the exemption for the entire year. This is not a monthly calculation. It is an annual test.

Example: You start the year at ₦80 million turnover. In November, you win a ₦30 million contract. Your year end turnover is ₦110 million. You exceed the limit and pay tax on your entire year’s profit.

Other taxes still apply

Zero percent CIT does not eliminate VAT (7.5%), withholding tax, PAYE for employees, or other levies. You remain responsible for all of them. 

Note on minimum tax

Small companies with turnover below certain thresholds may be exempt from minimum tax. Under previous Finance Acts, companies with gross turnover below ₦25 million were exempt from minimum tax.

Strategic benefits beyond the savings

These reforms do more than just save you money. They change what is possible for your business.

You can now formalise without tax punishment

Before 2025, staying informal was rational. Paying high tax rates made no sense when you could operate in cash. Now with 0% tax, formal registration gives you legal protection, banking access, and government contract opportunities at no tax cost.

Government procurement opens up

The Nigerian government spends trillions on contracts. Previously, small businesses could not compete because their tax burden made them uncompetitive. Now with 0% tax, you can bid lower and still keep the same profit.

You build a pathway to growth

Start small with zero tax and no audit. Build your business. When you eventually exceed the thresholds, you will have an established, compliant business ready for the next level.

Corporate governance guidelines for SMEs

The Financial Reporting Council of Nigeria (FRCN) launched SME Corporate Governance Guidelines in 2024. While voluntary, these guidelines help SMEs build structures for transparency, accountability, and access to finance. 

Common mistakes to avoid

Mistake one: Assuming you automatically qualify.

No. You must verify your numbers every year. Turnover changes. Assets grow. Employees increase. Check before claiming.

Mistake two: Ignoring the professional services exclusion.

If you are a consultant, lawyer, doctor, or accountant, you do not get 0% tax. Plan accordingly.

Mistake three: Failing to file because the tax is zero.

Penalties apply for non-filing. File on time, even with zero tax due.

Mistake four: Not monitoring thresholds.

That big contract could push you over the limit. Track your revenue quarterly. Set aside money for taxes if you think you might exceed.

Mistake five: Poor record-keeping.

The new reforms emphasize impeccable record-keeping. Scan and digitize every transaction daily. Use free apps like Genius Scan or Adobe Scan. Create a clear audit trail.

What about banks and investors?

Here is an honest reality check.

Audit exemption saves you money. But banks still like audited accounts. Some may refuse loans without them. Investors often require audited financials before putting in money.

You have a choice. Claim the exemption and save costs. Or maintain an audit voluntarily to keep financing options open.

Some smart business owners do this: Claim the exemption but get a lower cost “review engagement” or “compilation” service. It is cheaper than a full audit but gives more credibility than nothing.

Where to start tomorrow

Step one: Check your numbers.

Calculate your turnover from last year. List your fixed assets at gross value. Count your employees. Run the two tests separately for tax and audit.

Step two: Document everything.

Keep records of your calculations. Store your fixed assets register. Maintain proper books. Even without an audit, you need good records.

Step three: File your returns.

Submit your self-assessment return showing 0% tax if you qualify. For audit exemption, pass a board resolution and get shareholder approval. File your unaudited financial statements with CAC.

Step four: Monitor quarterly.

Do not wait until year-end. Check your revenue every three months. If you are approaching ₦100 million, plan accordingly.

Step five: Seek expert advice.

Speak with a qualified tax consultant or accountant familiar with the new regime. Many offer initial consultations affordably. 

Frequently Asked Questions

Q1: I am a small business. Do I automatically get 0% tax and audit exemption?

A: No. You must verify that you meet specific criteria for each exemption separately. For 0% tax: turnover ≤ ₦100M AND fixed assets ≤ ₦250M AND not professional services. For audit exemption: meet 2 of 3 criteria (turnover ≤ ₦120M, net assets ≤ ₦60M, employees ≤ 50) AND not in an excluded category. It is possible to qualify for one but not the other.

Q2: I am a lawyer with a small practice. Do I get 0% tax?

A: No. Legal services are professional services, expressly excluded from the 0% tax rate regardless of how small your turnover or assets. You pay the regular corporate income tax rate. However, you may still qualify for audit exemption under CAMA 2020 (no professional services exclusion for audit exemption).

Q3: If I qualify for 0% tax, do I still need to file tax returns?

A: YES. Filing is mandatory regardless of tax rate. The Tax Act 2025 explicitly requires all companies, including small companies with 0% tax, to file annual self-assessment returns. Non-filing attracts penalties even if no tax is due.

Q4: Can I claim exemptions for previous years retroactively?

A: For tax, no. The Tax Act 2025 is effective January 1, 2025. Prior years are taxed under the old law (30% rate). For audit, generally no. Exemption applies prospectively. If you filed audited accounts for prior years, you cannot retroactively un-audit them.

Q5: What happens if I exceed the thresholds mid-year?

A: Exemptions are assessed for the entire financial year. If you exceed thresholds at any point during the year, you likely lose exemption for the entire year. This is why threshold monitoring is critical.

Q6: Can I split my business into two companies to stay under thresholds?

A: Technically yes, but with significant risks. Both entities must have genuine separate substance (separate offices, staff, operations). Purely artificial splitting to avoid tax is tax evasion. FIRS can pierce the corporate veil if lacking commercial substance. Generally not recommended unless there are genuine business reasons.

Q7: Do I still need to register for VAT?

A: Yes. If your turnover exceeds ₦25 million (the VAT registration threshold), you must register for VAT and charge 7.5% VAT on taxable supplies. The 0% CIT exemption does not affect VAT obligations.

Q8: Can I claim exemption for one year and not the next?

A: Yes. Eligibility is assessed annually. If you qualify in Year 1, claim exemption. If you exceed thresholds in Year 2, you cannot claim exemption and must have an audit and pay full tax. If you fall back under thresholds in Year 3, you can claim exemption again (subject to consistency requirements for audit).

Q9: How do I prove I am not a professional services business?

A: Document your primary business activities including your CAC registration (business description), products sold or services provided, revenue breakdown by service or product type, and customer contracts. If there is any doubt, seek an advance ruling from FIRS.

Q10: Should I maintain an audit even though I am exempt?

A: Depends on your circumstances. Consider maintaining an audit if you need bank financing, anticipate investors, plan to sell the business within 2 to 3 years, have weak internal controls, value independent external review, or industry practice favors it. The exemption is optional. You can choose to audit despite eligibility. [7]

The Bottom Line

Nigeria’s 2025 tax reforms and CAMA 2020 audit exemptions create an unprecedented opportunity for small companies to operate profitably within the formal economy.

The 0% corporate income tax rate for qualifying small companies eliminates a massive burden that previously drove businesses into informality. The audit exemption removes another significant compliance cost.

But you must act correctly to benefit.

Misunderstanding the rules, exceeding thresholds unknowingly, or failing to comply properly can turn opportunity into disaster.

Key takeaways. Determine whether you qualify for tax exemption (turnover ≤ ₦100M, fixed assets ≤ ₦250M, not professional services) and audit exemption (meet 2 of 3 CAMA criteria, not excluded). Monitor your thresholds quarterly. File your returns even with 0% tax. Maintain proper books. Seek professional guidance.

The reforms are revolutionary. But they require active management.
