How Companies Can File Income Tax on Rev360 Before June 30

As the June 30 deadline for company income tax filing approaches in Nigeria, businesses are preparing to submit their annual tax returns via Rev360, the new digital platform from the Nigeria Revenue Service.

Rev360 replaces older tax filing systems and acts as a central portal for tax returns, payments, taxpayer records, and compliance management.

Many businesses, especially small and medium-sized ones, are facing new requirements and processes as they switch to Rev360. Tax professionals recommend starting the filing process early to avoid technical problems and compliance risks at the last minute.

Why the June 30 Deadline Matters

Companies whose financial year ends in December must file their annual Company Income Tax returns by June 30.

This filing rule applies even to businesses that had losses or qualify for tax exemptions.

Tax experts warn that missing the deadline can lead to penalties, interest charges, and trouble getting a Tax Clearance Certificate. This certificate is still needed for government contracts, banking, and other compliance needs.

Step One: Log Into the Rev360 Portal

Businesses must first access the Rev360 self-service portal with their registered credentials. It remains the primary reference for all tax-related activities on the platform.

Before filing, companies should check their profiles and make sure all corporate information is accurate and current.

Incorrect records can cause delays when submitting and validating your tax return.

Step Two: Select the Appropriate Tax Return

Once logged in, go to the filing section and select the right Company Income Tax return.

The system will automatically identify your filing category and provide the tax computation template for download if needed.

Make sure you have chosen the correct filing year before moving forward.

Step Three: Complete the Tax Computation Template

The Excel template you download is the main tool for your tax filing.

You will need to enter your financial details, such as revenue, allowable deductions, expenses, capital allowances, and any other tax adjustments for the year.

Rev360 handles many calculations in the template, which helps reduce manual errors and improve accuracy.

Tax consultants suggest checking all your entries carefully before submission to avoid mistakes that could trigger compliance reviews.

Step Four: Upload Supporting Documents

After you finish the computation template, save the file and upload it to the right section of the portal.

Depending on your company’s size and turnover, companies may need to upload audited financial statements and supporting schedules before the filing can be successfully processed.

The system will then show you a preview of your tax computation for a final check. : Review and Submit

Before submitting, double-check all your figures, attachments, and declarations.

If you find errors after filing, they can cause compliance problems and may require amendments.

Once you have confirmed everything, submit your returns electronically through Rev360 and keep the acknowledgement records for your files.

Tax professionals recommend not waiting until the last days of June, since heavy filing activity can slow down the portal.

Expert View

Tax analysts see Rev360 as a big step forward in Nigeria’s move to digitise tax administration and improve compliance monitoring.

The platform brings together taxpayer information, filing records, payments, and communication in one place. Over time, this should help reduce paperwork and improve efficiency.

However, experts point out that businesses still have a learning curve. If you wait too long to prepare, you might have trouble with documentation, data checks, and heavy portal traffic near the deadline.

For most organisations, filing early is still the best approach.

Common Mistakes Companies Should Avoid

Many businesses think that being tax-exempt means they do not have to file returns.

Tax professionals say this is still one of the most expensive mistakes small companies make.

Even if your business qualifies for zero Company Income Tax, you still need to file returns to stay compliant.

Companies should also make sure their documentation is complete, their financial entries are accurate, and they submit on time.

Not following these rules can affect your Tax Clearance Certificate approval and lead to more regulatory problems.

The Push Toward Digital Tax Compliance

The launch of Rev360 is part of a bigger push by tax authorities to modernise tax administration and make things more transparent.

As tax filing becomes more digital, businesses are expected to report on time, keep accurate records, and meet real-time compliance checks.

With the June 30 deadline coming up, companies that prepare early and file accurately are more likely to avoid penalties and keep their business running smoothly.
