A VAT invoice is not just any invoice with a tax line added at the bottom. Under Nigerian law, it is a specific legal document that must meet the exact format prescribed by the Federal Inland Revenue Service (FIRS). If any mandatory field is missing or incorrect, your buyer cannot claim input VAT — and you face potential penalties.
This guide explains the correct VAT invoice format for Nigeria, field by field, with practical ₦ examples for common business types. For the full picture on Nigerian invoicing requirements, see the InvoiceGenerator.ng guide.
Who Must Issue VAT Invoices?
Any business with an annual taxable turnover of ₦25 million or more is required to register for VAT and issue a tax invoice (also called a VAT invoice) for every taxable supply. Businesses below the ₦25 million threshold are not required to charge VAT, but many register voluntarily — particularly when their clients are large corporates or government agencies that need VAT invoices to claim input tax.
Key rule: if you charge VAT on an invoice without being VAT-registered, FIRS can demand repayment of all VAT collected plus a 150% penalty. Only issue VAT invoices if you are registered.
The Correct VAT Invoice Format: All Required Fields
Field 1 — Document Title: "Tax Invoice"
Write Tax Invoice prominently at the top of the document. This label distinguishes it from a proforma invoice, a quotation, a delivery note, or a standard invoice not subject to VAT.
Field 2 — Your Business Details
Include all of the following:
- Registered business name (exactly as registered with CAC)
- Registered address — full street address, not a P.O. Box
- Phone number and email address
- RC or BN number (Corporate Affairs Commission registration number)
Example:
Prime Digital Services Limited 7B Admiralty Way, Lekki Phase 1, Lagos Tel: 0802 345 6789 | hello@primedigital.ng RC: 1456789
Field 3 — Tax Identification Number (TIN)
Your TIN is mandatory on every tax invoice. It is an 8-digit number issued by FIRS (e.g., 12345678-0001). Without it, your invoice is not FIRS-compliant, regardless of how correct everything else is.
Field 4 — VAT Registration Number
Your VAT registration number is separate from your TIN and is issued when you register for VAT. It must appear on every tax invoice. Format: typically begins with the letters "VRN" followed by digits (e.g., VRN-12345678-0001).
Field 5 — Unique Invoice Number
Each invoice must carry a unique, sequential invoice number that does not repeat within a calendar year. FIRS requires an unbroken sequence.
Recommended format:
INV-2026-001, INV-2026-002, INV-2026-003...
Never skip or reuse numbers. A gap in your invoice sequence is a red flag during audits.
Field 6 — Invoice Date
The date on which the invoice is issued. For VAT invoices, Nigerian law requires that you issue the invoice within 15 days of the end of the month in which the supply took place.
Example: Service delivered on 22 March 2026 → invoice must be issued by 15 April 2026.
Field 7 — Your Client's Details
Include:
- Full name or registered company name
- Address
- TIN (strongly recommended for B2B — required for the buyer to claim input VAT)
Field 8 — Description of Supply
Describe each item or service clearly and specifically. Vague entries like "Services Rendered" are inadequate for VAT purposes.
| Description | Qty | Unit Price | |---|---|---| | Social media management — March 2026 | 1 month | ₦120,000 | | Paid ad campaign setup and management | 1 | ₦80,000 | | Monthly performance report | 1 | ₦25,000 |
Field 9 — Subtotal, VAT, and Total
This is the section most businesses get wrong. VAT must be shown as a separate line item, not embedded in the total.
Correct format:
Subtotal: ₦225,000 VAT (7.5%): ₦16,875 Total Due: ₦241,875
Incorrect format:
Total (including VAT): ₦241,875 ✗
The buyer needs to see the VAT amount explicitly to claim it as input credit.
Field 10 — Payment Due Date and Terms
State clearly when payment is due and any penalty for late payment:
Payment due: 30 April 2026 (Net 30) Late fee: 2% per month on overdue balances
Field 11 — Payment Details
Provide:
- Bank name
- Account name (must match your registered business name)
- NUBAN account number
- Paystack or Flutterwave payment link (if applicable)

TAX INVOICE
Prime Digital Services Limited 7B Admiralty Way, Lekki Phase 1, Lagos | RC: 1456789 TIN: 12345678-0001 | VRN: VRN-12345678-0001
Invoice #: INV-2026-028 Invoice Date: 2 April 2026 Due Date: 2 May 2026 (Net 30)
Bill To: TechCorp Nigeria Limited Plot 44, Central Business District, Abuja TIN: 98765432-0001
| Item | Qty | Unit Price | Total | |---|---|---|---| | Social media management (March 2026) | 1 | ₦120,000 | ₦120,000 | | Paid ad campaign management | 1 | ₦80,000 | ₦80,000 | | Monthly analytics report | 1 | ₦25,000 | ₦25,000 | | Subtotal | | | ₦225,000 | | VAT (7.5%) | | | ₦16,875 | | Total Due | | | ₦241,875 |
Payment: Bank: Zenith Bank | Account Name: Prime Digital Services Limited | Account: 2012345678
Payment due 2 May 2026. A late fee of 2% per month applies after the due date.
VAT on Exempt and Zero-Rated Items
Not every supply attracts VAT at 7.5%. The following categories are VAT-exempt under Schedule 1 of the VAT Act:
- Basic food items (unprocessed agricultural products)
- Medical and pharmaceutical products
- Educational materials (books, newspapers)
- Baby products
- Exported services and goods
If your invoice contains a mix of taxable and exempt items, calculate VAT only on the taxable portion and clearly label which lines are exempt.
Example — catering business:
Jollof rice and proteins (exempt food supply): ₦50,000 — VAT: ₦0 Event venue arrangement and décor (taxable service): ₦150,000 — VAT: ₦11,250 Total VAT: ₦11,250
Common VAT Invoice Mistakes
- Not separating VAT from the subtotal — VAT must be a distinct line item
- Using a TIN instead of a VAT registration number — these are different numbers
- Charging VAT without registration — this attracts a 150% penalty
- Rounding VAT incorrectly — always calculate 7.5% precisely; do not round up for convenience
- Issuing the invoice late — beyond 15 days after month-end is a compliance breach
