VAT registration is a legal obligation for Nigerian businesses that cross the ₦25 million annual turnover threshold. It is also a smart voluntary step for smaller businesses working with corporate clients. This guide walks you through the complete registration process, your ongoing obligations, and how to avoid costly mistakes.
Who Must Register for VAT in Nigeria?
Under the VAT Act (as amended by the Finance Act 2020), every person or business that makes taxable supplies in Nigeria with an annual turnover of ₦25 million or more must register for VAT with FIRS.
"Person" in this context includes:
- Individuals (sole traders, freelancers)
- Partnerships
- Limited liability companies
- NGOs making taxable supplies
- Foreign companies making supplies in Nigeria
Voluntary registration is also allowed for businesses below the threshold - and is often advisable if you:
- Work primarily with VAT-registered corporate clients who need input VAT claims
- Want to reclaim input VAT on your own business purchases
- Want to appear more established and credible
VAT Registration: What You Need Before You Start
Gather these documents before beginning your FIRS registration:
For Individuals / Sole Traders
- Valid government-issued ID (NIN, national passport, or driver's licence)
- Bank Verification Number (BVN)
- Tax Identification Number (TIN) - if not yet registered, get a TIN first
- Proof of business address (utility bill, lease agreement, or bank statement)
- Evidence of business activity (a few recent invoices or contracts)
For Registered Companies (Limited Liability)
- Certificate of Incorporation (CAC)
- Memorandum and Articles of Association
- Form CAC 1.1 (formerly Form CO2/CO7) - list of directors
- Company TIN
- Directors' IDs and BVNs
- Proof of registered office address
- Evidence of taxable turnover (management accounts, bank statements)
Step-by-Step: How to Register for VAT with FIRS
Step 1: Get a TIN (if you do not already have one)
A Tax Identification Number is a prerequisite for VAT registration. You can obtain a TIN:
- Online: via the FIRS TIN registration portal at tin.firs.gov.ng
- In person: at your nearest FIRS office
- For individuals: your NIN-linked TIN can be retrieved via USSD (*346#) or the FIRS portal
Step 2: Register on the FIRS e-Tax Portal
Go to etax.firs.gov.ng and create an account (or log in if you already have one).
- Select "VAT Registration" from the services menu
- Complete the VAT registration form - you will need:
- TIN
- Business name and address
- Nature of business / ISIC code
- Annual turnover (estimated if new business)
- Bank account details
- Upload the required supporting documents (see list above)
- Submit the application
Step 3: FIRS Review and Verification
FIRS will review your application. For most applications:
- Online applications: processed within 5–10 working days
- In-person applications: may be processed same-day or within a few days
FIRS may contact you to verify documents or conduct a premises inspection for larger businesses.
Step 4: Receive Your VAT Registration Certificate
Once approved, FIRS issues a VAT Registration Certificate showing your VAT registration number (which is your TIN). Display this certificate at your business premises.
Your VAT registration number must appear on every tax invoice you issue from the date of registration.
Your Ongoing VAT Obligations After Registration
Registration is just the beginning. As a VAT-registered business, you must:
1. Charge VAT on All Taxable Supplies
Add 7.5% VAT to every invoice for taxable goods or services. Show it as a separate line item. Do not blend it into your price.
2. Collect and Hold VAT for FIRS
The VAT you collect from clients is not your money - it is FIRS's. Hold it separately from your operating funds.
3. File Monthly VAT Returns
VAT returns are due by the 21st of the following month. For example, March VAT is due by 21 April.
Your monthly return declares:
- Output VAT - VAT you charged on your sales invoices
- Input VAT - VAT you paid on qualifying business purchases
- Net VAT payable - output VAT minus input VAT
4. Remit Net VAT to FIRS
Pay the net VAT due via the FIRS e-Tax portal or at a designated bank. Late remittance attracts a penalty of 10% of the tax due plus interest at the CBN MPR rate.
5. Maintain VAT Records for 6 Years
Keep copies of:
- All sales invoices issued (output VAT records)
- All purchase invoices received (input VAT records)
- Monthly VAT returns filed
- VAT payment receipts
Input VAT: What You Can Reclaim
As a VAT-registered business, you can reclaim VAT paid on business purchases - this is called input VAT. Examples:
- VAT on office supplies and stationery
- VAT on professional services (legal, accounting)
- VAT on business equipment and software
- VAT on marketing and advertising costs
You cannot reclaim input VAT on:
- Personal or non-business expenses
- Purchases used to make VAT-exempt supplies
- Entertainment expenses (in most cases)
You need a valid tax invoice from a VAT-registered supplier to support every input VAT claim.
Common VAT Registration Mistakes in Nigeria
- Registering late - once you cross ₦25 million turnover, registration is mandatory. Penalties apply for late registration.
- Charging VAT before registration is confirmed - only charge VAT once FIRS has issued your certificate.
- Not separating VAT from revenue in your accounts - VAT collected is a liability, not income. It must be tracked separately.
- Missing the monthly filing deadline - 10% penalty plus interest for late filing, even if there is no VAT due.
- Issuing VAT invoices without your registration number - your TIN/VAT number must appear on every tax invoice.
Create FIRS-Compliant VAT Invoices
Once you are VAT-registered, every invoice you issue must be a proper tax invoice with your TIN, itemised services, and VAT shown at 7.5%.
InvoiceGenerator.ng automatically formats your invoices for FIRS compliance - with VAT calculated, your TIN field, and sequential numbering built in.
