Quick Summary
Closing a Nigerian business doesn’t end your tax obligations. The Federal Inland Revenue Service (FIRS) requires you to file cessation returns, settle all outstanding taxes, and obtain a final Tax Clearance Certificate (TCC) before the Corporate Affairs Commission (CAC) can deregister your company. With Nigeria’s Company Income Tax (CIT) collections surging to N9.21 trillion in 2025 and N1.37 trillion in Q1 2026 alone, FIRS is aggressively enforcing compliance — even for businesses that are shutting down. Missing the six-month filing deadline or failing to notify FIRS within 90 days can trigger audits, penalties (starting at ₦25,000), and even personal liability for directors.
Quick Answer
Yes, you must file cessation returns within six months of ceasing business and notify FIRS of your intention to deregister within 90 days of stopping trade. This applies to all companies registered with CAC, including small businesses with zero turnover. You’ll need final financial statements, a computation of assessable profits, payment of any Company Income Tax (CIT) and Education Tax (EDT) due, and a Tax Clearance Certificate (TCC) before CAC can process your dissolution. Expect accountant fees of ₦50,000 to ₦200,000 for preparing final accounts and returns.
What Happens to Your Company Tax When You Close? (Cessation Explained)
When a Nigerian company permanently stops trading, it doesn’t automatically disappear in the eyes of the law — or the tax authorities. The company remains a legal person until it is fully dissolved by the CAC. During that period, FIRS still expects you to account for all taxes up to the date you stopped trading.
What does “cessation” mean for tax purposes?
Under Section 29 of the Companies Income Tax Act (CITA) Chapter C21, a company that permanently ceases to carry on business must file cessation returns [source]. The FIRS Information Circular 2021/10 clarifies that assessable profits are calculated from the beginning of the accounting period to the date of cessation [source]. This means you cannot simply file a “nil” return for the final year — you must compute profit up to your last day of trading.
Legal status of the company during winding up
Even after you stop trading, the company maintains its legal personality until dissolution. It can still sue, but it can only be sued with leave of court [source]. The winding-up process is governed by the Companies and Allied Matters Act (CAMA) 2020, which provides three modes:
- By Court Order — usually when the company is insolvent or unable to pay debts.
- Voluntary — shareholders pass a special resolution to wind up.
- By Supervision of Court — a voluntary winding up that continues under court supervision.
Tax compliance is a prerequisite for dissolution in all three modes. For context on how other regulatory frameworks affect Nigerian businesses, read our guide on Navigating Business Risk in Nigeria: A 2026 Guide to Resilience and Growth.
Cessation vs. normal annual filing
| Aspect | Normal Annual Filing | Cessation Filing |
|---|---|---|
| Deadline | 6 months after year-end | 6 months from cessation date |
| Period covered | Full accounting year | From start of accounting period to cessation date |
| Notification required | No separate notification | Must notify FIRS within 90 days of cessation |
| Penalties for late filing | ₦25k first year, ₦50k subsequent | Same, but FIRS may also assess estimated tax |
| TCC required | For ongoing operations | Required for deregistration |
Who Must File Cessation Returns? (Obligations & Exceptions)
Not every business closure triggers a cessation filing. Here’s who is required to file and who may be exempt.
Obligated companies
- Any company registered with CAC that permanently stops trading in Nigeria — regardless of size or turnover.
- Non-resident companies with Nigerian-source income (e.g., from a fixed base or permanent establishment) must also file cessation returns when they stop deriving that income.
- Companies that have been dormant but never formally dissolved — if you decide to close, you must file cessation returns even if you had no activity.
Exceptions and special cases
- Small companies (turnover ≤ ₦25 million) are exempt from CIT (0% rate) but must still file cessation returns to confirm their tax status and obtain a TCC for deregistration.
- Companies that merely change their business structure (e.g., from a limited liability company to a business name) are not ceasing — they are reorganising. However, if the old company is dissolved, cessation rules apply.
- Under the Nigeria Tax Administration Act (NTAA) 2025, a company that ceases trade must designate a representative to manage its tax affairs after cessation [source]. This representative can be a director, liquidator, or tax agent.
⚠️ Penalty for non-registration
If your company has never registered for a Tax Identification Number (TIN), FIRS can impose a penalty of ₦25,000 for the first year and ₦50,000 for each subsequent year of non-registration [source]. This applies even if you are closing down.
Cessation Deadlines and Penalties — The 2026 Calendar
Missing deadlines is the fastest way to incur penalties. Here is the exact timeline you must follow.
Filing deadline
Under Section 29(4) of CITA, you must file cessation returns within six months from the date of cessation [source]. The “date of cessation” is the last day your company carried on business — not the date you filed for winding up.
Notification deadline
Under the Finance Act (now consolidated into NTAA 2025), you must notify FIRS of your intention to deregister within 90 days of cessation [source]. This notification is separate from the filing of returns.
Basis of assessment — timing matters
The FIRS Circular 2021/10 explains that the year of assessment depends on when cessation occurs:
- Cessation between January and June: You must file and pay tax in the same year (the year of cessation).
- Cessation between July and December: Filing may fall into the succeeding year [source].
Example
If your company ceased trading on 15 March 2026, you must file cessation returns by 15 September 2026 and pay any tax due in the 2026 assessment year. If you ceased on 15 October 2026, the filing deadline is 15 April 2027, and the tax will be assessed for the 2027 year.
Penalties for non-compliance
| Offence | Penalty |
|---|---|
| Late filing of cessation returns | ₦25,000 (first year), ₦50,000 (subsequent years) |
| Late payment of tax due | 10% of the tax amount plus interest at the CBN monetary policy rate |
| Failure to notify FIRS within 90 days | No fixed penalty in CITA, but FIRS can impose a penalty of up to ₦50,000 under general provisions |
| Failure to designate a representative (NTAA 2025) | FIRS may refuse to issue TCC or delay deregistration |
Note: Penalty amounts are as per FIRS FAQ and CITA provisions [source].
Step-by-Step Guide to Filing Cessation Returns (With Naira Costs)
Follow these seven steps to ensure you meet all FIRS requirements and obtain the TCC needed for CAC deregistration. For more on managing your business finances, see our guide on Mastering Cash Management in Nigeria: A Comprehensive 2026 Guide for Businesses.
-
Step 1: Notify FIRS in writing within 90 days of cessation
Write a formal letter (or file via the FIRS e-portal) stating your intention to cease business and deregister. Include your company name, RC number, TIN, and the exact cessation date. Keep a copy with proof of delivery (registered mail or portal acknowledgment).
Cost: Free if filed online; registered mail costs about ₦500–₦1,000.
-
Step 2: Prepare final financial statements up to cessation date
You need a set of accounts covering the period from the start of your accounting year to the cessation date. This must include a profit and loss account, balance sheet, and notes. Engage a qualified accountant or tax practitioner.
Cost: Accountant fees range from ₦50,000 to ₦200,000 depending on the complexity of your business and the volume of transactions.
-
Step 3: Calculate assessable profits and tax liability
Your accountant will compute the assessable profit and apply the appropriate CIT rate:
- Large companies (turnover > ₦100 million): 30% CIT
- Medium companies (turnover > ₦25 million but ≤ ₦100 million): 20% CIT
- Small companies (turnover ≤ ₦25 million): 0% CIT (but still file)
- Education Tax (EDT): 3% of assessable profits for all companies (except those exempt under the Finance Act)
Example calculation
If your medium company had assessable profits of ₦10 million up to cessation, CIT = ₦2 million (20%) and EDT = ₦300,000 (3%). Total tax due = ₦2.3 million.
-
Step 4: File cessation returns on FIRS e-filing portal
Log in to the FIRS e-filing portal and select “Cessation Return” under the CIT module. Upload your financial statements and computation. The portal will generate an assessment.
Cost: Free (no filing fee).
-
Step 5: Pay any tax due via Remita or bank transfer
Once the assessment is issued, pay the tax due through Remita (using your TIN as the payer ID) or via direct bank transfer to FIRS’s designated account. Keep the payment receipt.
Cost: No filing fee, but you pay the tax amount.
-
Step 6: Designate a representative under NTAA 2025
Submit a formal letter to FIRS designating a person (e.g., a director, liquidator, or tax agent) to manage the company’s tax affairs after cessation. This is required for the final TCC issuance.
Cost: Free (just a letter).
-
Step 7: Obtain Tax Clearance Certificate (TCC) for the final year
After FIRS confirms all taxes are paid and returns filed, apply for a TCC for the cessation period. The TCC is required by CAC before they will process your deregistration.
Cost: TCC application is free on the FIRS portal, but some tax practitioners charge a handling fee of ₦0–₦5,000.
Cost summary table
| Item | Estimated Cost (₦) |
|---|---|
| Notification letter (registered mail) | 500 – 1,000 |
| Accountant fees for final accounts | 50,000 – 200,000 |
| Filing cessation returns (portal) | 0 |
| Tax payment (CIT + EDT) | Varies |
| Designation letter | 0 |
| TCC application | 0 – 5,000 |
| Total (excluding tax due) | ₦50,500 – ₦206,000 |
Common Mistakes That Trigger FIRS Audits When Closing
Even well-intentioned business owners make errors that attract FIRS scrutiny. Avoid these six pitfalls. Understanding the broader regulatory environment is key — see our Nigeria’s Economy in 2026: Navigating AI, Food Security, and CBN Policy guide for context.
🚫 Common Mistakes to Avoid
- Not filing cessation returns at all — FIRS can assess estimated tax based on prior years’ profits, plus penalties. This can be far higher than your actual liability.
- Using the wrong cessation date — The cessation date must be the actual last day of trading — not the date you filed for winding up or the date your CAC status changed. If you use a later date, FIRS may argue you were still trading and assess additional tax.
- Ignoring Education Tax (EDT) — EDT at 3% of assessable profits is often forgotten. Even small companies that pay 0% CIT may still owe EDT if their profits exceed the exemption threshold. Check the latest Finance Act provisions.
- Failing to notify FIRS within 90 days — The notification requirement under the Finance Act is separate from filing returns. If you miss the 90-day window, FIRS may impose a penalty or delay your TCC.
- Not keeping records for 6 years after cessation — Under CITA, you must retain all books and records for six years after the end of the year of assessment to which they relate. FIRS can reopen an assessment within that period if they suspect underpayment. Destroying records early is a red flag.
- Dissolving the company before settling tax — If you dissolve the company through CAC before FIRS confirms all taxes are paid, the directors become personally liable for the outstanding tax debts. Liquidators are also personally liable for ensuring tax compliance before distributing assets to shareholders [source].
Frequently Asked Questions
Do I need to file cessation returns if my company had no income?
Yes. Even if your company had zero turnover or made a loss, you must file cessation returns to confirm that no tax is due. FIRS will not issue a TCC without a filed return.
What is the penalty for late filing of cessation returns?
The penalty is ₦25,000 for the first year of default and ₦50,000 for each subsequent year. Additionally, late payment of tax attracts a 10% penalty plus interest at the CBN rate.
Can I file cessation returns myself without an accountant?
You can, but it is risky. The computation of assessable profits, especially for cessation, requires knowledge of CITA rules. Errors can lead to audits. Most business owners use a tax practitioner (cost: ₦50,000–₦200,000).
How long does it take to get a TCC after filing cessation returns?
If all returns are correct and tax is paid, FIRS typically issues a TCC within 2–4 weeks. Delays occur if there are outstanding audits or discrepancies.
What happens if I don’t file cessation returns at all?
FIRS can assess estimated tax based on your previous years’ profits, impose penalties, and refuse to issue a TCC. The CAC will not deregister your company without a TCC, leaving the company legally alive and exposed to further liabilities.
Does cessation filing apply to non-resident companies?
Yes. A non-resident company with Nigerian-source income that ceases to derive that income must file cessation returns in Nigeria.
Can I wind up my company without FIRS clearance?
No. Under CAMA 2020, the CAC requires a Tax Clearance Certificate (TCC) or a letter of no objection from FIRS before it can process a winding-up application.
