In 2026, VAT record-keeping in Nigeria has moved from "paper in a folder" to a digital-first compliance model. Under the Nigeria Tax Administration Act 2025, the Nigeria Revenue Service (NRS) now has the power to request direct access to your electronic accounting records.
To be fully compliant, you must keep the following records for at least six (6) years.
1. Mandatory Sales Records (Output VAT)
Since e-invoicing is now mandatory for businesses with turnover above ₦100 million, your sales records must be "fiscalized":
- Electronic Invoices: Copies of all invoices issued, which must include the QR Code and Invoice Reference Number (IRN) generated by the NRS portal.
- Sales Ledger/Register: A summary of all taxable and exempt sales.
- Credit & Debit Notes: Records of any price adjustments or returned goods, which must also be processed through the e-invoicing system.
2. Purchase & Expense Records (Input VAT)
To claim back the VAT you’ve paid (Input VAT), your documentation must be airtight:
- Validated Invoices from Suppliers: You can only claim input VAT if your supplier provided a valid e-invoice. Manual receipts are no longer sufficient for VAT recovery in 2026.
- Import Documents: If you import goods, you must keep the Single Goods Declaration (SGD) forms and evidence of VAT paid at the port to the Nigeria Customs Service.
- Expense Vouchers: Receipts for services (utilities, rent, professional fees) which are now fully claimable under the new law.
3. Operational & System Records
- VAT Monthly Schedules: The digital spreadsheets or system reports used to prepare your monthly returns (due by the 21st).
- Bank Statements: Clear evidence of payments to suppliers and receipts from customers to verify the "timing" of your VAT liability.
- Fiscalization Logs: If you use a third-party System Integrator (e.g., linked to QuickBooks or Zoho), you must keep logs showing that your transactions were successfully transmitted to the NRS.
4. Summary of Retention Rules (2026)
| Record Type | Retention Period | Format |
|---|---|---|
| General VAT Records | 6 Years | Digital (Primary) & Physical |
| Assets/Capital Expenditure | 6 Years after disposal | Digital |
| Invoices without TINs | Prohibited | N/A |
The "Fraud" Exception
While the standard rule is 6 years, the Nigeria Tax Administration Act 2025 states that if the NRS suspects fraud, willful default, or gross negligence, the 6-year limit is waived. In such cases, they can demand records from any year in the company's history.
Pro-Tip: Ensure your accounting software has a "Tax Audit" export feature. In 2026, NRS auditors often prefer a direct data dump over browsing through scanned PDFs.
