Corporate taxpayers across Nigeria have just 24 hours remaining to meet the June 30 deadline for filing Companies Income Tax returns, following a final urgent notice posted by the Nigeria Revenue Service on its official social media channels. The agency made clear that the compliance window will close precisely at midnight and will not be extended.
Businesses are required to submit their audited financial statements along with supporting tax computations through the Taxpayer Self Service Portal. NRS officials have cautioned that the automated system will enforce the deadline strictly, and have urged companies to file early to sidestep the network congestion and portal slowdowns that typically accompany last-minute submissions.
Failing to meet the cutoff carries steep consequences. Companies that miss the deadline face significant monetary penalties, as well as accruing interest on any outstanding tax liabilities. Beyond the immediate financial cost, the NRS has the authority to restrict portal access for non-compliant entities — a measure that can abruptly disrupt routine corporate banking transactions and stall day-to-day business operations.
An even more far-reaching consequence is the potential loss of Tax Clearance Certificates. A valid TCC is a mandatory document for companies seeking to bid on public and private tenders, secure import and export licences, or execute foreign exchange transactions. Without it, a defaulting business could find itself effectively shut out of commercial markets for the remainder of the fiscal year.
The NRS notice serves as a final call to action for finance directors, auditors, and business owners who have yet to complete their filings. Taxpayers seeking compliance guidance or technical support before the window closes are directed to Rev 360, the official Nigeria Revenue Service portal.
