Common Mistakes When Filing Annual Returns

Below are the most frequent mistakes when filing annual returns in Nigeria, why they happen, and how to avoid penalties.

Missing The Deadline

This is the most common mistake when filing annual returns. Companies must file within 42 days after the Annual General Meeting, business names must file not later than 30 June each year, and incorporated trustees must file between 30 June and 31 December.

Late filing attracts penalties that add up over time. For example, late filing penalties per year are 3,000 naira for a small company, 5,000 naira for a private company that is not small, and 10,000 naira for a public company.

If you have a backlog, our Annual Returns Filing Service at Entrepreneurs.ng can regularise filings quickly and help you avoid more penalties. Reach out on WhatsApp- 08188122223 or contact@redahlia.com.

Not Updating the Company Or Business Information Before Filing

Many annual returns errors at CAC happen because directors, shareholders, addresses, or share capital were changed during the year but not updated before the return.

The portal may flag inconsistencies and reject the filing. Always complete post-incorporation updates first, then file your annual return.

Using The Wrong Form For Your Entity

Another frequent mistake when filing annual returns is using a company form for a business name or a trustees form for a company.

CAC provides distinct forms and timelines for companies, business names, and incorporated trustees. Using the wrong form leads to rejection and delays.

What It Looks LikeWhy It MattersQuick FixPrevention

If you manage multiple entities, our Business Registration services at Entrepreneurs.ng can streamline records and forms so each return uses the correct documentation.

Submitting Incomplete Or Inaccurate Information

Incorrect RC or BN numbers, wrong AGM dates, missing trustee details, or poor quality scans cause queries and resubmissions.

Trustees must attach audited accounts with their annual return during the filing window. Quality control before upload saves time and cost.

Typos in RC or BN, wrong AGM date, illegible PDFsQueries, failed submissions, delayed complianceCross check identifiers, confirm dates from board minutes, rescan documents clearlyUse a two person review before you click submit and store source documents in a central folder

Ignoring Payment Confirmation Or Portal Status

Payment may be debited but not reflect on the CAC portal due to processing issues.

If you submit without confirming payment status and acknowledgement, the filing can remain pending and lead to a late status. Always verify payment and download the acknowledgement slip.

What It Looks LikeWhy It MattersQuick FixPrevention
You pay but do not see confirmation or acknowledgementFiling stays pending and may later be treated as lateUse the portal payment status tools, retry off peak, and contact CAC support if neededAlways save the payment receipt and acknowledgement to a compliance folder immediately

Portal Login Errors

Many entrepreneurs experience portal login issues when filing annual returns. Wrong usernames, forgotten passwords, and browser-related errors are common.

These login mistakes can delay filings until after deadlines, exposing the business to penalties.

What It Looks LikeWhy It MattersQuick FixPrevention
Multiple failed login attemptsAccount lockout and delayed filingReset password immediately using the official portalSave updated login details in a secure password manager

If you prefer not to deal with these technical frustrations, our Annual Returns Filing Service at Entrepreneurs.ng manages the entire process securely and on time. Reach out on WhatsApp- 08188122223 or contact@redahlia.com.

Filing For The Wrong Year Or Skipping Dormant Years

Another mistake when filing annual returns is submitting for the wrong year or skipping dormant years.

Every year must be accounted for, whether the company was active or dormant. Ignoring dormant years leads to penalties that continue to build.

Confusing Annual Returns With Tax Returns

A common misconception is thinking CAC annual returns and FIRS or LIRS tax returns are the same. They are distinct obligations.

Annual returns confirm the existence and compliance of a business at CAC, while tax returns cover income and tax payments. Filing one does not exempt you from the other.

Failing To Keep Proof Of Filing

Many entrepreneurs file correctly but forget to download and save acknowledgement slips or receipts. This proof is critical for defending compliance in case of queries, tenders, or investor checks.

Without evidence, your business can be treated as non-compliant even if filings were made.

Consequences Of Mistakes In Annual Returns

Mistakes when filing annual returns do not just create paperwork issues. They carry financial, legal, and reputational consequences that affect the stability and growth of your business.

Financial Penalties That Accumulate

Every late or incorrect filing attracts surcharges. For example, penalties for late filing are charged annually and increase depending on the type of business.

Small companies face thousands of naira in fines, while public companies may pay tens of thousands each year in penalties. These costs add up quickly and reduce funds available for operations and expansion.

Risk Of Inactive Or Struck Off Status

Repeated mistakes, especially missing deadlines or ignoring backlogs, can result in your company being flagged as inactive on the Corporate Affairs Commission database.

If left unresolved, the business risks being struck off entirely, which removes its legal recognition and makes it impossible to operate formally.

Barriers To Funding And Opportunities

Investors, banks, and government agencies check CAC compliance status before approving loans, grants, or tender applications.

A company with errors in its annual returns or flagged as inactive may be disqualified automatically. This reduces your chances of attracting capital or securing contracts.

Legal And Reputational Risks

Failing to meet statutory obligations exposes directors and business owners to potential legal queries. Beyond compliance, reputational damage follows.

A company known for poor governance and repeated mistakes when filing annual returns is less likely to be trusted by partners or investors.

Impact Of Mistakes In Annual Returns

Missing deadlinesPenalties appliedLoss of legal standing
Using wrong formsFiling rejectionDelayed compliance status

Correcting mistakes early reduces penalties, prevents your business from being labelled inactive, and protects your access to opportunities.

Entrepreneurs.ng offers services such as Annual Returns Filing, Business Registration, and Ask An Expert consultations to help you address errors quickly and safeguard your compliance record.

How To Correct Mistakes After Filing Annual Returns

Mistakes when filing annual returns can be corrected, but the process depends on the type of error and how long it has been outstanding.

Acting quickly helps reduce penalties and ensures your business remains compliant with the Corporate Affairs Commission.

Identify The Type Of Mistake

The first step is to determine what went wrong. Was it a missed deadline, a wrong form, or incomplete information? Each mistake has a specific correction path.

Mistake In Annual ReturnsCorrection StepExtra Cost
Missed deadlineFile backlog year by year starting with the oldestPenalties apply for each year
Wrong form usedResubmit using the correct CAC formNew filing fee
Incomplete detailsUpdate records, rescan documents, and refilePossible resubmission fee
Skipped dormant yearFile dormant return with nil statementPenalty applies

File Backlogs Chronologically

If you missed multiple years, you cannot jump to the current year. The CAC requires filings to be done chronologically, beginning with the earliest pending year.

This clears backlogs and prevents penalties from continuing to accumulate.

Submit Post-Incorporation Updates First

Where details like directors, addresses, or share capital have changed, file the necessary post-incorporation updates before refiling annual returns.

This ensures that the portal records match your submission and reduces rejection risk.

Resolve Payment And Portal Issues

If your mistake relates to unconfirmed payments or portal errors, retrieve receipts, use the CAC payment status tool, and, if needed, escalate through official support.

Always confirm acknowledgement slips before assuming the process is complete.

Seek Professional Assistance

For complicated cases, such as multiple backlogs or frequent rejections, it is more efficient to use a professional service. Entrepreneurs.ng provides an Annual Returns Filing Service to regularise your filings quickly

Practical Checklist To Avoid Annual Return Mistakes

The easiest way to prevent mistakes when filing annual returns is to follow a simple checklist every year. This ensures that deadlines are met, documents are accurate, and payments are confirmed.

FAQs: Mistakes When Filing Annual Returns

What Happens If I Miss The Annual Returns Deadline?

Missing the deadline is one of the top mistakes when filing annual returns. You will face financial penalties that accrue each year.

Over time, your business may be flagged as inactive or struck off the CAC register. To remedy, you must file the outstanding returns chronologically, pay accumulated penalties, and bring your filings up to date.

Can I Correct Errors After I Submit An Annual Return?

Yes. If you discover mistakes—wrong form used, incorrect information, or missed years, you can correct them.

Identify the error type, submit post-incorporation updates first (if needed), then refile the return with correct details. You will also pay any extra filing fees and penalties.

Does Filing Annual Returns Count As Filing My Tax Returns?

No. A frequent misconception is confusing annual returns with tax returns. They are distinct obligations.

Annual returns relate to CAC compliance, while tax returns go to FIRS or LIRS and involve income, profits, and tax payments. Filing one does not exempt the other.

Do Dormant Or Non-Trading Businesses Need To File Annual Returns?

Yes. Even if your business is not active or did not generate revenue, you must still file annual returns. Assuming dormancy exempts you is a recurring mistake when filing annual returns and leads to penalties.

What If I Use The Wrong Form For My Entity?

Using the wrong form, such as filing a company form for a business name, is a common error when filing annual returns.

The CAC will reject that submission. The fix is to select the correct form for your entity (Business Name, Company, or Incorporated Trustee) and resubmit.

What Should I Do If My Payment Doesn’t Reflect on The CAC Portal?

One of the most frustrating mistakes when filing annual returns is completing payment that doesn’t reflect. First, confirm the payment was debited from your account.

Then use CAC’s “Check Payment Status” feature, contact support if needed, and delay submission until the portal reflects the payment. Always download the acknowledgement slip.

How Far Back Can I File Backlog Returns?

You can file multiple years of outstanding returns, even several years back. However, you must do so chronologically (oldest first) and pay penalties for each year of default. The longer the delay, the higher the accumulated cost.

Can My Business Be Struck Off Because Of Filing Mistakes?

Yes. Persistent errors, missed filings, or defaulting for multiple years can lead CAC to flag your business as inactive or strike it off the register. That removes its legal status and complicates reinstatement.

Can Someone Else File My Annual Returns For Me?

Yes. You can authorise an accredited agent or compliance service to file on your behalf. This helps avoid mistakes when filing annual returns if you lack the time or expertise.

What Documents Are Commonly Rejected Because Of Mistakes?

Typical document errors include illegible scans, missing signatures, incorrect AGM minutes, or missing audited accounts (for companies or NGOs). Ensuring document quality and completeness prevents many mistakes when filing annual returns.

    I am unable to file the annual return because after filling the necessary information and I click on save and continue, “object” pops up.
