State Internal Revenue Service IRS

You may have come across the terms LIRS and FIRS, especially for Lagos state citizens. Now you may wonder if the LIRS collects taxes, so does the FIRS why is that so? Well, that is the concept of the state Internal Revenue Service. 

While we have the FIRS, the State IRS also exists as a tax collector. For more specifics, the State Internal Revenue Service (IRS) in Nigeria is like the financial engine that powers each state. 

It’s the part of the government responsible for collecting taxes within a specific state. Now, you might wonder, why is this so important? 

Well, think of all the things your state needs to run smoothly, building schools, maintaining roads, providing healthcare, and more. All of this requires money, and that’s where the State IRS comes in.  

It collects the funds needed to make sure your state can carry out these essential projects and provide public services. In this article, we are going to delve into the role of the state IRS. Discover its functions, impact, and importance in funding state projects. 

What is the State Internal Revenue Service? 

The State Internal Revenue Service, often referred to as the State IRS, is a crucial part of Nigeria’s tax system. It’s like the local tax collection arm of the government, but it operates at the state level. Its main job is to collect taxes within a specific state’s borders. 

What are the duties and significance of the state IRS? 

So, why is the State IRS so important? Well, it has a couple of vital roles. 

Firstly, it helps individual states become financially independent. By gathering taxes effectively, it means states don’t have to rely as much on funds from the federal government. This financial independence is a big deal because it gives states more control over their finances and the ability to carry out their projects. 

Secondly, the State IRS is the source of money for many state-level projects and public services. Think about things like building roads, running schools, and providing healthcare – all these require money, and the State IRS is the place that gathers those funds. 

Which laws empower the State IRS?

To do its job, the State IRS operates within a set of laws specific to each state. These laws are like the rulebook for taxation within that state. But there’s also a bigger rulebook – the federal tax laws and the constitution – that all these state laws have to follow.

What is the difference between the state IRS and the Federal IRS 

The primary difference between the State Internal Revenue Service (IRS) and the Federal Inland Revenue Service (FIRS) in Nigeria lies in their jurisdiction, functions, and the level of government they serve: 


State IRS: State IRS agencies operate at the state level. Each state in Nigeria has its own IRS responsible for tax collection and administration within that state’s boundaries. 

FIRS: The Federal Inland Revenue Service, on the other hand, operates at the federal level and covers tax matters that apply nationwide. 


State IRS: State IRS agencies are responsible for collecting state-level taxes and levies. These can include personal income tax, property tax, consumption tax, and other taxes and levies that are specific to the state. They also handle tax matters related to individuals and businesses within their respective states. 

FIRS: The Federal Inland Revenue Service deals with federal-level taxes, including corporate income tax, value-added tax (VAT), and other taxes that apply across the entire country. FIRS focuses on federal tax policy and administration. So, they only collect taxes that accrue to the federal government.

FIRS: The taxpayer base for FIRS includes businesses and organizations operating at the federal level, often with a wider scope of operations that can span multiple states.

Do the state IRS and FIRS have to work together?

Yes, the state IRS and FIRS work together, especially for Nigeria’s intricate tax landscape. Collaboration between State Internal Revenue Service (IRS) agencies and the Federal Inland Revenue Service (FIRS) is a crucial element for ensuring effective tax administration and compliance. This collaborative effort harmonizes tax collection and fosters an environment of tax discipline and accountability. Here is how they collaborate to achieve this: 

1. Data Sharing and Integration 

One key aspect of collaboration between State IRS agencies and the FIRS is data sharing and integration. To facilitate efficient tax administration, these entities share taxpayer information and transaction data. This exchange helps to identify taxpayers operating across state boundaries and ensures that they fulfill their tax obligations at both the state and federal levels. 

2. Uniform Tax Policies and Regulations 

Collaborative efforts between State IRS agencies and the FIRS extend to the development of uniform tax policies and regulations. While state governments have the autonomy to set state-specific tax rates and levies, a harmonized approach is encouraged to prevent inconsistencies that may arise from conflicting tax laws. 

3. Capacity Building and Training 

State IRS agencies benefit from training and capacity-building initiatives supported by the FIRS. These programs equip tax administrators with the necessary skills and knowledge to carry out their functions effectively. It also promotes standardized tax assessment and enforcement procedures. 

4. Technology Integration 

In today’s digital age, technology plays a pivotal role in tax administration. Collaborative efforts include the integration of technological solutions for tax collection and reporting. This ensures transparency and reduces opportunities for tax evasion and fraud. 

5. Auditing and Compliance Checks 

State IRS agencies and the FIRS collaborate on auditing and compliance checks. Joint audits and investigations can uncover tax discrepancies and inconsistencies, helping to identify non-compliant taxpayers and take appropriate action. 

6. Dispute Resolution 

In cases where taxpayers have disputes that involve both state and federal tax matters, collaborative mechanisms help in resolving these disputes efficiently and fairly. Taxpayers benefit from a streamlined dispute resolution process. 

7. Policy Advocacy and Reform 

Working in tandem, State IRS agencies and the FIRS advocate for tax policy reforms that enhance revenue collection and encourage tax compliance. Their collective voice influences federal and state tax policy decisions. 

8. Resource Allocation 

Revenue generated through collaboration is allocated based on established revenue-sharing formulas. This equitable distribution ensures that both state and federal governments receive their fair share of tax revenue.

They are responsible for collecting various taxes and levies, ensuring taxpayer registration and compliance, managing revenue allocation, and educating taxpayers.
