Nigeria Tax Wahala Is Not What You Think

Nigeria has spent years building a tax system that became difficult to follow. Different laws, different taxes, different agencies and plenty of paperwork created a system that even businesses struggled to navigate.

The government decided to change that.

On June 26, 2025, President Bola Tinubu signed four tax reform laws into effect. They cover the Nigeria Tax Act, tax administration, the Nigeria Revenue Service and the Joint Revenue Board. The idea is to bring Nigeria's fragmented tax system into a more unified framework and reduce the duplication that businesses and taxpayers have complained about for years.

The reforms became operational from January 1, 2026, after a transition period.

And yes, FIRS is no longer the name to look out for.

The Federal Inland Revenue Service has been replaced by the Nigeria Revenue Service (NRS), which now handles the federal tax administration under the new framework. The NRS has also introduced digital services for tax registration, filing, payments, tax clearance and other taxpayer services.

This is where things get interesting for the average Nigerian.

First, the part that affects your salary

Under the new personal income tax structure, the first ₦800,000 of annual income is taxed at 0%.

After that, the tax rate increases progressively across different income bands, reaching 25% for income above ₦50 million.

There is also a new rent relief.

Individuals can claim 20% of annual rent paid, subject to a maximum relief of ₦500,000. So if you pay ₦1 million in rent, your potential relief is ₦200,000. If you pay ₦3 million, 20% would be ₦600,000, but the relief stops at ₦500,000. The relief reduces the income on which tax is calculated.

For someone earning close to the lower end of the income scale, these changes can make a meaningful difference.

But then we get to businesses.

SMEs have something to gain too

One of the biggest changes is that qualifying small companies can benefit from a 0% Company Income Tax rate. Under the new framework, a small company is generally one with annual gross turnover of up to ₦100 million and fixed assets not exceeding ₦250 million.

But there is a catch that many business owners are likely to miss.

Tax exemption does not mean tax compliance disappears.

A business can have no company income tax to pay and still have obligations around registration, identification, record keeping and filing.

The NRS has also moved towards a much more digital system. Tax IDs are now being linked to individuals and businesses, and the NRS provides online services for filing, payments, tax clearance and e-invoicing.

This means that the old "my business is small, nobody knows me" approach is becoming harder to rely on.

The informal sector is where the reforms could get particularly interesting.

In July 2026, new presumptive tax regulations were introduced for people whose income cannot be reliably established because they don't keep adequate records. The standard presumptive rate is 1% of actual or estimated turnover, while nano businesses meeting specific conditions, including turnover of no more than ₦12 million and having no fixed premises or employees, are exempt from that regime.

So the government is trying to bring more informal businesses into the tax system while also giving very small businesses some protection.

And that is probably where much of the current wahala comes from.

The government is saying: make the system simpler, protect the small guy and bring more people into the tax net.

Businesses are asking: okay, but what exactly do I need to register, file, pay and keep records for?

That's a fair question.

The reforms are a major change in how Nigerians interact with the tax system. The real test now isn't just whether the government can collect more money. It is whether an ordinary worker, trader, freelancer or small business owner can understand the rules without needing a tax consultant to explain every step.

For now, the safest move for individuals and businesses is simple: know your Tax ID, keep records and understand which rules actually apply to you.

Because the tax system has changed.

And pretending it hasn't is probably going to cost more than learning it.
