Good tax filing begins every month, not a few days before the deadline. The safest approach is to identify the correct obligations, keep evidence for each transaction and close your books regularly.
Picture Chinedu, finance manager for an engineering supplier in Enugu. Two weeks before filing, sales figures do not match the bank, supplier receipts are missing and withholding-tax credits sit in different email threads. The deadline is only exposing a year-long records problem.
Know which authority and taxes apply
Company income tax, VAT, withholding tax, payroll obligations and state-level charges do not all follow the same process. Confirm your registration details, TIN, filing periods and current official channels with a qualified Nigerian tax professional.
Build a monthly compliance folder
Reconcile bank accounts, sales invoices, supplier bills, expenses, payroll, VAT and withholding-tax evidence. Close each month with explanations for differences, not unexplained balancing figures.
Invoice → Payment → Receipt → Tax treatment → Reconciliation → Archive
How Odoo can help
When sales, purchases, expenses and payments pass through one controlled system, finance can trace transactions and produce cleaner reports. Odoo does not decide the tax treatment for you; the chart of accounts, taxes, approvals and local setup still require competent review.
Prepare the annual return properly
The Nigeria Tax Administration Act 2025 provides for annual self-assessment returns by companies. It also sets circumstances in which a small company may provide taxpayer-attested accounts instead of audited statements. Confirm whether your company qualifies and which supporting documents are required.
FAQ
Can software file every Nigerian SME tax automatically?
No. Software improves records and calculations, but the business remains responsible for correct classification, evidence and filing through the applicable official channel.
Is this tax advice?
No. This is general operational information. Use a qualified Nigerian tax practitioner for advice specific to your entity, sector and transactions.
