VAT Filing Requirements for Registered Businesses in Nigeria

Value Added Tax (VAT) is one of the most important taxes every registered business in Nigeria must handle correctly. It applies to the sale of goods and services and is regulated by the Federal Inland Revenue Service (FIRS). Businesses that collect VAT from customers must file and remit it to the government every month. Failure to comply can lead to penalties, loss of reputation, and possible closure of operations.
Many business owners, especially small and medium enterprises, often find VAT filing confusing. Yet, once you understand what is required, the process becomes simple and manageable.
What VAT Means
Value Added Tax is a consumption tax charged at every stage of production or distribution of goods and services. In Nigeria, the standard VAT rate is 7.5%. Businesses charge VAT on their sales (known as output tax) and pay VAT on goods or services they buy (known as input tax). When filing, the business remits the difference between output and input tax to the FIRS.
Why Registered Businesses Must File VAT
VAT filing is not optional for businesses that are registered with the FIRS. Once your business reaches a certain turnover threshold, you are required to charge, collect, and remit VAT monthly. Filing VAT ensures that your business remains compliant with tax regulations and eligible for government tenders or contracts.
Businesses Required to Register for VAT
All companies, enterprises, and individuals involved in selling goods or offering taxable services in Nigeria must register for VAT. Even freelancers, consultants, and digital service providers who earn taxable income are required to comply. Companies that fail to register for VAT within six months of starting operations may face penalties, which can increase with continued non-compliance.
Documents Needed for VAT Filing
Before you can file VAT returns, ensure you have the necessary records and documents ready. These include:
- Tax Identification Number (TIN)
- VAT Registration Certificate
- Monthly sales invoices showing VAT charged
- Purchase receipts showing VAT paid on inputs
- Bank payment receipts or proof of VAT remittance
Having these records organized will make your filing process smooth and error-free.
How to File VAT Returns
Registered businesses are required to file VAT returns on or before the 21st day of the month following the transaction month. The process can be completed online or at the nearest FIRS office.
Step 1: Calculate Output Tax
Output tax refers to the VAT your business collects from customers. For example, if you sell a product worth ₦100,000, you must add 7.5% VAT, which equals ₦7,500. That ₦7,500 becomes your output tax for that transaction.
Step 2: Calculate Input Tax
Input tax is the VAT your business pays on goods and services purchased from other suppliers. For instance, if you buy raw materials worth ₦50,000 and pay ₦3,750 as VAT, that is your input tax.
Step 3: Determine VAT Payable
To determine how much VAT to remit, subtract your input tax from your output tax.
VAT Payable = Output VAT – Input VAT
If your output VAT is higher than your input VAT, you remit the difference to the FIRS. If your input VAT is higher, the balance can be carried forward to offset future VAT liabilities.
Step 4: File VAT Returns Online
Businesses can now file VAT online through the FIRS TaxPro Max portal (https://taxpromax.firs.gov.ng). Log in using your TIN and password, then select “VAT Filing.” Input your monthly sales and purchase details, confirm the calculations, and submit.
After submission, a payment reference will be generated. Use it to pay your VAT through an approved bank or online payment system.
Step 5: Keep Records of All Filings
Once payment is made, download and save your payment receipt and acknowledgment slip. These documents serve as proof that your VAT has been filed and remitted for the month. Keeping detailed records helps during audits or tax reviews.
Common Mistakes to Avoid During VAT Filing
Businesses often make errors that result in penalties or compliance issues. Avoiding these mistakes ensures smooth tax management.
Late Filing
Submitting VAT returns after the deadline attracts penalties. Always mark your calendar to ensure filings are completed on or before the 21st of every month.
Incorrect Calculations
Always double-check your VAT figures before submission. Wrong entries can trigger audits or cause discrepancies in your tax records.
Ignoring Input VAT
Many businesses forget to include VAT paid on purchases. Recording input VAT correctly helps reduce the total VAT payable and ensures accurate reporting.
Using Wrong TIN or Details
Always verify your Tax Identification Number and company details before submitting. Incorrect information can delay processing or invalidate your filing.
Failure to File Zero Returns
Even if your business did not make sales in a particular month, you must still file a zero VAT return. Failure to do so counts as non-compliance.
Benefits of Proper VAT Filing
Complying with VAT requirements offers multiple advantages beyond avoiding penalties.
Legal Compliance
Proper VAT filing ensures that your business stays compliant with Nigerian tax laws. This helps you avoid fines and maintain a clean financial record.
Business Credibility
Companies that file VAT regularly appear more trustworthy to clients, banks, and investors. It shows that your operations are transparent and professionally managed.
Access to Government Contracts
Most government projects require contractors to submit evidence of VAT compliance. Filing your VAT monthly ensures your business qualifies for such opportunities.
Easier Financial Audits
When VAT is filed accurately, your records become easier to audit. This simplifies future accounting, especially during tax investigations or financial reviews.
Digital VAT Filing Advantages
The FIRS online platform has made VAT filing faster and more convenient for registered businesses. Digital filing reduces paperwork, saves time, and minimizes human errors.
Real-Time Processing
Online filing provides instant confirmation once your VAT return is submitted and payment made. This helps you maintain accurate and up-to-date records.
Improved Transparency
All transactions are stored electronically, making it easier to retrieve or verify past filings. This transparency promotes better accountability in financial reporting.
Reduced Paperwork
Digital VAT filing eliminates the need to visit tax offices physically. Businesses can now file from anywhere, improving productivity and convenience.
Penalties for Non-Compliance
Businesses that fail to file or pay VAT face strict penalties from the FIRS.
Late Filing Penalty
A penalty of ₦50,000 is imposed for the first month of default and ₦25,000 for each subsequent month of non-filing.
False Declaration
Submitting false VAT returns can lead to legal action, financial fines, and loss of business reputation.
Interest on Unpaid VAT
Failure to remit collected VAT on time attracts additional interest charges until payment is completed.
