Nigerian State IRS Tax Guides 2026: Lagos, Abuja (FCT) & Rivers Compared

Nigeria's federal structure means tax administration is split between the Nigeria Revenue Service (NRS) at the federal level and the State Internal Revenue Services (SIRS) at the state level. For individuals and businesses operating in Nigeria, understanding which tax authority handles what — and how rules differ from state to state — is essential for staying compliant. This guide compares the tax landscapes across three of Nigeria's most economically significant jurisdictions: Lagos State, the Federal Capital Territory (Abuja), and Rivers State.

The Division of Tax Powers in Nigeria

Under the Nigeria Tax Act 2026 (NTA 2026) , taxes are divided between the federal and state governments based on legislative competence. The NRS administers federal taxes including:

• •Company Income Tax (CIT) for companies incorporated in Nigeria
• •Value Added Tax (VAT) at 7.5%
• •Petroleum Profits Tax (PPT) for upstream oil and gas
• •Capital Gains Tax (CGT) for companies
• •Tertiary Education Tax (TET) at 3%
• •Customs and Excise Duties
• •Stamp Duties on corporate transactions

State Internal Revenue Services administer:

• •Personal Income Tax (PAYE and direct assessment) for individuals resident in the state
• •Withholding Tax on contracts and services for individuals
• •Stamp Duties on individual transactions
• •State-specific levies and charges
• •Business premises registration
• •Road taxes and vehicle licensing
• •Development levies
• •Signage and advertising fees

Lagos State Internal Revenue Service (LIRS)

Lagos State is Nigeria's commercial capital and contributes a significant share of national internally generated revenue. The Lagos State Internal Revenue Service (LIRS) is widely regarded as Nigeria's most sophisticated state tax authority.

Personal Income Tax (PAYE) in Lagos

The LIRS administers PAYE for all employees working in Lagos State — regardless of where their employer's head office is located. Under the NTA 2026, the residence rule determines which state collects your PAYE: you pay to the state where you physically work.

Tax is calculated using the Consolidated Relief Allowance (CRA) , which is the higher of ₦200,000 or 1% of gross income, plus 20% of gross income. After deducting the CRA, pension contributions (up to 8% of gross emolument), and other statutory reliefs, the following graduated rates apply:

Key Filing Requirements in Lagos

• •Annual PAYE Returns: Employers must file annual returns by 31 January of the following year, detailing all employees, their gross emoluments, deductions, and tax remitted
• •Monthly Remittance: Tax deducted from salaries must be remitted to the LIRS by the 10th day of the following month
• •Direct Assessment: Self-employed individuals, freelancers, and professionals must file annual returns by 31 March
• •Tax Clearance Certificate (TCC): Issued upon request for individuals with up-to-date tax payments. The LIRS issues TCCs digitally via its e-TCC portal

State-Specific Levies in Lagos

Lagos imposes several state-specific levies that businesses and residents must budget for:

• •Business Premises Registration: All businesses with physical locations in Lagos must register and pay an annual fee. Rates range from ₦10,000 for small shops to ₦50,000 for large commercial premises
• •Development Levy: A flat ₦100 per person per annum for all taxable individuals. Collected alongside PAYE or direct assessment
• •Land Use Charge: Property owners pay an annual charge computed as a percentage of the assessed market value of the property. Rates are lower for owner-occupied residential property and higher for commercial property
• •Signage and Advertisement Fees: Businesses with outdoor signage must obtain annual permits from the Lagos State Signage and Advertisement Agency (LASAA). Fees depend on the size, location, and type of signage

Lagos Digital Advantage

The LIRS has invested heavily in technology. The e-Tax platform allows individuals and businesses to:

• •File PAYE and direct assessment returns online
• •Generate payment reference numbers for remittances
• •Apply for and download Tax Clearance Certificates
• •Access tax calculators and compliance tools

FCT Internal Revenue Service (FCT-IRS)

The Federal Capital Territory Internal Revenue Service (FCT-IRS) administers personal income tax and state-level taxes for residents and businesses in Abuja. The FCT-IRS operates under a unique legal framework — it is a federal territory, not a state, but it has equivalent taxing powers under the NTA 2026.

Personal Income Tax in Abuja

The PAYE rates and bands in the FCT mirror the national rates (identical to the Lagos table above — these are set by the Personal Income Tax Act, harmonised within the NTA 2026). However, administration and enforcement differ.

Key Filing Requirements in the FCT

• •Monthly PAYE Remittance: Employers must remit PAYE by the 10th day of the following month. The FCT-IRS has a dedicated employer portal
• •Annual PAYE Returns: Due by 31 January. The FCT-IRS has been strict about late filing — penalties are enforced
• •Direct Assessment: Self-employed individuals file by 31 March. The FCT-IRS actively pursues professionals, particularly in the legal, medical, and consulting sectors
• •Tax Clearance Certificates: Available through the FCT-IRS portal. Processing typically takes 7–14 working days

State-Specific Levies in Abuja

• •Business Premises Fee: Annual registration required. Rates vary by business size and sector, generally starting at ₦5,000 for micro businesses
• •Development Levy: ₦100 per taxable person per annum
• •Tenement Rate: Property owners in certain areas may be assessed for tenement rates. Administration is handled by the Abuja Municipal Area Council (AMAC) and other area councils, coordinated with the FCT-IRS
• •Signage Fees: Businesses must obtain permits from the Abuja Metropolitan Management Council (AMMC) for outdoor advertising

The FCT Advantage for Corporate Headquarters

Many companies headquartered in Abuja with branches in other states face dual compliance obligations. While the NRS handles federal taxes nationally, PAYE for Abuja-based employees goes to the FCT-IRS, while employees in other states pay through their respective SIRS. This requires robust payroll systems that can handle multi-state tax allocations.

Rivers State Internal Revenue Service (RSIRS)

Rivers State, with Port Harcourt as its economic hub, is the heart of Nigeria's oil and gas industry. The Rivers State Internal Revenue Service (RSIRS) administers personal income tax and state-level taxes for one of Nigeria's wealthiest states.

Personal Income Tax in Rivers

The PAYE rates are the same national rates. However, Rivers has been particularly aggressive in tax enforcement, focusing on:

• •Oil and gas service companies: Contractors and service providers to the petroleum industry
• •High-net-worth individuals: Professionals, business owners, and landlords
• •Informal sector operators: Traders, artisans, and transporters are increasingly brought into the tax net

Key Filing Requirements in Rivers

• •Monthly PAYE Remittance: Due by the 10th day of the following month
• •Annual PAYE Returns: Due by 31 January. The RSIRS has enhanced its employer compliance monitoring — discrepancies between monthly remittances and annual returns trigger audits
• •Direct Assessment: Due by 31 March. Rivers State has been expanding its direct assessment base through market enumeration exercises
• •Contractor Registration: Non-resident contractors executing projects in Rivers State must register with the RSIRS and comply with withholding tax obligations at the state level

State-Specific Levies in Rivers

• •Business Premises Registration: Annual renewal required. Rates start at ₦7,500 for small businesses
• •Development Levy: ₦100 per person per annum
• •Hotel Occupancy and Restaurant Consumption Levy: A levy on hotel stays and restaurant bills within the state. This is Rivers-specific and distinct from VAT
• •Infrastructure Development Levy: Large companies operating in Rivers may be assessed for an infrastructure levy, particularly in certain local government areas
• •Vehicular and Road Taxes: Vehicle registration, renewal, and road traffic fees administered by the RSIRS in coordination with the Rivers State Ministry of Transport
• •Land and Property Tax: Administered at the local government level but coordinated with the RSIRS for assessment purposes

Oil and Gas Considerations

Rivers State hosts numerous oil and gas companies and their service providers. While petroleum profits tax and CIT go to the NRS, the economic activity generates significant state-level tax obligations:

• •Employee PAYE for thousands of oil sector workers residing in Rivers
• •Contractor withholding tax where the contractor is an individual or partnership (not a limited company)
• •Casino and gaming taxes for hotels and entertainment venues catering to the oil industry workforce

Comparative Summary: Lagos vs FCT vs Rivers

Multi-State Compliance Strategies

If your business operates across multiple states, consider these strategies:

• •Centralised payroll with state-based tax allocation: Your payroll system should assign each employee to their correct state of residence and calculate PAYE accordingly. The employer remits to each SIRS separately
• •Consolidated compliance calendar: Track deadlines for each state. A single missed deadline in any state can result in penalties
• •Business premises registration in each state: Every physical office, branch, or outlet requires separate registration
• •Engage state-specific tax consultants: Rules and enforcement priorities differ. Local expertise matters
• •Use Taxee's multi-state compliance tools: Our platform supports multi-state PAYE filing, automated TCC applications across jurisdictions, and a unified compliance dashboard for all your state tax obligations

Key Takeaways

• •The NRS handles federal taxes (CIT, VAT, CGT for companies, TET), while State IRS bodies handle PAYE, direct assessment, and state-specific levies
• •PAYE follows the residence rule — you pay to the state where you physically work
• •Lagos, Abuja, and Rivers all apply the same national PAYE rates, but differ significantly in administration, enforcement, and additional levies
• •Lagos has the most advanced digital infrastructure; Rivers is most aggressive on oil and gas sector enforcement; Abuja is strict on professional tax compliance
• •Multi-state businesses need robust payroll systems and compliance calendars to manage obligations across jurisdictions
• •State-specific levies like Land Use Charge (Lagos), Tenement Rate (Abuja), and Hotel Levy (Rivers) must be budgeted for separately
