Imagine paying for a service, settling the supplier’s invoice in full, and moving on with business as usual.

Months later, during a tax review, you discover that you are expected to account for VAT on that same transaction, when the supplier did not charge VAT.

Your first reaction might be: Why am I responsible for VAT when the supplier didn’t charge it?

This question lies at the heart of the reverse VAT debate in Nigeria.

What is Reverse VAT?

Under the normal VAT system, a supplier charges VAT on an invoice, collects it from the customer, and remits it to the tax authority.

Under the reverse charge mechanism, the responsibility shifts from the supplier to the customer. Rather than paying VAT to the supplier, the customer is required to account for and remit the VAT directly to the tax authority.

The objective is to ensure that taxable transactions do not escape the VAT net.

While the concept appears straightforward, its application often generates debate, particularly in three common situations.

Scenario 1: Imported Services from Foreign Suppliers

Consider a Nigerian company that engages a UK consulting firm for advisory services worth N20 million.

The foreign consultant issues an invoice without Nigerian VAT and receives payment in full.

Under the reverse charge mechanism, the Nigerian company is expected to account for VAT on the transaction and remit it to the tax authority.

From the government’s perspective, this makes sense. Since the service is consumed in Nigeria, VAT should be paid in Nigeria.

However, many businesses see it differently.

The argument is simple:

We have already paid the supplier. Why should we now bear the additional responsibility of calculating and remitting VAT ourselves?

This remains one of the most common reverse VAT issues during tax audits.

Scenario 2: Local Suppliers Issuing Invoices Without VAT

The debate becomes more complicated when the supplier is located in Nigeria.

Imagine a local consultant provides services worth N2 million but issues an invoice without VAT. The customer pays the invoice exactly as presented.

Years later, during a tax review, questions arise regarding whether VAT should have been accounted for on the transaction.

Many taxpayers argue that responsibility should rest with the supplier because the supplier issued the invoice.

The tax authority may take the view that VAT on a taxable transaction should not be lost simply because it was omitted from the invoice. The consumer of the goods or services may bear the VAT in respect of the transaction.

This creates a difficult question:

Should the customer bear responsibility for a supplier’s failure to charge VAT?

Scenario 3: Small Businesses Exempt from VAT

Another area of debate involves small businesses that are exempt from VAT payment due to their turnover threshold.

Suppose a large company hires a small business that falls below the VAT threshold.

The small business issue an invoice without VAT because it is legally exempt from charging VAT.

Later, the taxpayers show up and request that the large company pays the reverse VAT on their consumption.

Conclusion

From the government’s perspective, reverse VAT helps protect revenue and ensures that taxable transactions do not escape the tax net.

From the taxpayer’s perspective, it can feel like an additional compliance burden, particularly where the supplier did not charge VAT or was legally exempt from doing so.

What is clear is that reverse VAT is no longer an issue limited to foreign service providers. Businesses must now pay close attention to invoices issued without VAT, transactions involving exempt suppliers, and situations where the responsibility for VAT may unexpectedly shift to them.
