How to File Annual Returns with CAC in Nigeria

Filing annual returns with the Corporate Affairs Commission (CAC) is one of the core compliance tasks for registered businesses in Nigeria.

Reviewed by Henry Agwu, Chartered Accountant.

Filing annual returns with the Corporate Affairs Commission (CAC) is one of the core compliance tasks for registered businesses in Nigeria, and it applies to companies, business names, and incorporated trustees. Under the Companies and Allied Matters Act (CAMA) 2020, annual returns are part of the record that keeps your entity active and properly reflected on the CAC register.

What annual returns mean

Annual returns are not the same thing as tax returns. In simple terms, CAC annual returns are a statutory filing that confirms your business is still in operation and gives CAC updated information about the entity, while tax returns go to the tax authorities. This distinction matters because many business owners confuse the two and end up filing one while ignoring the other.

For companies, the filing obligation is tied to the CAMA framework covering annual returns under Sections 417 to 424 of CAMA 2020, as reflected in the CAC annual return form CAC 19. For incorporated trustees, CAC also expects annual reporting as part of its regulatory oversight.

Who must file

All registered business entities under CAC are expected to file annual returns, although the deadline and filing format depend on the entity type. That includes private limited companies, business names, and incorporated trustees such as NGOs, churches, mosques, clubs, and associations.

Here is the practical breakdown:

Business names file yearly after the initial grace period from registration.
Companies file yearly, except in the first year of incorporation.
Incorporated trustees file annually, commonly with a June deadline.

Filing deadlines

The deadline depends on the type of entity and the rule that applies to it. CAC guidance and the annual return form point to these timelines: business names file after the first 18 months from registration and then annually, companies file yearly after the first year, and incorporated trustees file not later than 30 June each year.

A useful way to understand the timing is this:

Entity type	Filing timing	Reference
Business name	After the first 18 months, then yearly
Company	Every year, except the first year of incorporation
Incorporated trustee	Not later than 30 June each year

If a company already has an annual general meeting cycle, the filing is commonly completed within the post-AGM period, but the legal requirement is still to keep the return current for each financial year.

Documents you need

The documents required depend on the entity type and the filing route. For business names, you usually need the registration number, the year of return, and updated business particulars if any changes occurred. For companies, CAC guidance and third-party summaries of current practice point to company details, current officers, and financial statements or a statement of affairs depending on the company’s size.

Typical items include:

CAC registration number or RC/BN number.
Year being filed.
Current business address and updated particulars, if changed.
Details of directors, shareholders, or trustees.
Financial statements or statement of affairs, where applicable.

For incorporated trustees, a statement of affairs or similar financial disclosure is commonly required as part of the filing package.

How to file online

The CAC filing process is done through the CAC post-incorporation platform, with the public portal also used for entity access and related services. The usual online flow is straightforward: log in, select the registered entity, open the annual returns service, complete the form, pay the fee, upload supporting documents where required, and submit for processing.

Use this sequence:

Log in to the CAC portal with your account credentials.
Locate the registered entity by RC number or business name.
Select the annual returns option.
Enter the required filing details for the relevant year.
Generate the payment invoice and complete payment online.
Upload supporting documents where the entity type requires them.
Submit and save the acknowledgement slip after approval.

For many businesses, the portal process is the most efficient path because it reduces physical visits and creates a digital trail for compliance records.

Fees and penalties

CAC fees for annual returns changed under the current schedule of fees released in the Federal Republic of Nigeria Official Gazette and published by CAC in 2025. The exact amount varies by entity type and company size, so it is important to match the filing fee to the correct structure.

A practical fee view is shown below:

Entity type	Typical annual return fee	Late filing exposure
Business name	₦5,000	Late penalty applies
Small company	₦5,000	Late penalty applies
Other companies	₦10,000 and above depending on class	Late penalty applies
Incorporated trustee	₦5,000	Late penalty applies

Some recent guides and practitioner notes also mention recurring late penalties and daily default charges, but the safest approach is to verify the applicable fee class at the point of filing because CAC fee updates are issued through official schedules and portal charges can change. For that reason, the filing invoice on the CAC platform is the figure that should be treated as the operative amount for the specific return being filed.

What happens if you file late

Late filing exposes the business to penalties and compliance problems, and those consequences are separate from any tax or other regulatory obligations. A business that repeatedly ignores annual returns can be marked inactive or struck off the register, which affects its ability to transact smoothly with banks, counterparties, and regulators.

The practical risks include:

Penalty charges for each late filing cycle.
Difficulty obtaining certified copies or making post-incorporation changes.
Compliance red flags on the CAC record.
In severe cases, removal from the register after prolonged default.

This is why annual returns are treated as a governance obligation, not just paperwork.

Common filing mistakes

Many filing problems come from simple errors that delay approval or cause rejection. The most common ones are filing the wrong entity type, entering an incorrect RC or BN number, using outdated officer details, and uploading documents that do not match the return year. Another common mistake is confusing annual returns with tax filing and doing one while skipping the other.

Other errors include:

Selecting the wrong year of return.
Ignoring changes in directors, trustees, or address.
Using old financial statements that do not match the filing year.
Waiting until after the deadline and then paying avoidable penalties.

Real examples

A small private company with a valid registration and no changes in directors may only need its company details, the relevant annual return form, and the fee invoice for online filing, depending on what the portal requests. If the company misses the deadline, the filing cost rises because the late penalty joins the normal annual return fee.

For an incorporated trustee, such as an NGO or faith-based association, the filing usually requires more attention because the entity may need to show its statement of affairs and current trustee records. If the entity has not filed for several years, the CAC record may show unresolved defaults, which means the arrears need to be cleaned up through back filing.

Why this matters

Annual returns help keep a Nigerian business visible in the corporate registry, which matters for banking, contracts, grants, and institutional credibility. In practice, many organizations only notice the problem when they need a Certified True Copy, want to update directors, or try to use the business for formal transactions.

For founders, the main takeaway is that CAC compliance is part of the cost of running a formal business in Nigeria. The filing is relatively small compared with the disruption created by an inactive or non-compliant record.
