Calculate your taxes with HRPayHub's updated income tax calculator

The Nigeria Tax Act 2025, which came into effect at the beginning of this fiscal year, represents a detailed analysis  of how personal income tax is calculated, collected, and administered across the country.

The new tax structure introduces enhanced progressivity, with rates now ranging from 0% to 25%, while simultaneously implementing a complete restructuring of the relief system that eliminates the traditional Consolidated Relief Allowance (CRA) in favor of a more targeted approach. These changes have far-reaching implications for payroll management, tax planning, and compliance across all sectors of the Nigerian economy.

Comprehensive Breakdown of the 2025 Tax Structure in Nigeria 

The 2025 personal income tax structure represents a sophisticated graduated system designed to ensure equitable contribution across all income levels. The new brackets have been carefully calibrated to provide relief for lower-income earners while ensuring appropriate contribution from higher-income individuals.

Complete 2025 Tax Bracket Breakdown:

Bracket 1: ₦0 - ₦300,000 (7% Rate) This foundational bracket affects all Nigerian taxpayers and represents a slight increase from previous rates. The 7% rate applies to the first ₦300,000 of annual income, ensuring that even the lowest earners contribute to national development while maintaining affordability.

Bracket 2: ₦300,001 - ₦600,000 (11% Rate) The second bracket captures income between ₦300,001 and ₦600,000, taxed at 11%. This bracket primarily affects mid-level employees and represents a moderate increase that balances revenue generation with taxpayer capacity.

Bracket 3: ₦600,001 - ₦1,100,000 (15% Rate) Income falling within ₦600,001 to ₦1,100,000 faces a 15% tax rate. This bracket encompasses many professional-level salaries and represents a significant portion of the Nigerian middle class.

Bracket 4: ₦1,100,001 - ₦1,600,000 (19% Rate) The fourth bracket, covering ₦1,100,001 to ₦1,600,000, is taxed at 19%. This level typically includes senior professionals, middle management, and specialized technical roles across various industries.

Bracket 5: ₦1,600,001 - ₦3,200,000 (21% Rate) Income between ₦1,600,001 and ₦3,200,000 faces a 21% tax rate. This bracket captures senior management positions, specialized consultants, and experienced professionals across multiple sectors.

Bracket 6: ₦3,200,001 - ₦49,999,999 (24% Rate) The penultimate bracket covers income from ₦3,200,001 to ₦49,999,999, maintaining the 24% rate that was previously the highest tier. This bracket includes executive positions, senior partners, and high-earning professionals.

Bracket 7: ₦50,000,000 and Above (25% Rate) The new highest bracket, introduced in 2025, applies a 25% rate to income exceeding ₦50,000,000 annually. This bracket specifically targets ultra-high earners and represents the government's commitment to progressive taxation principles.

Mathematical Application of Progressive Taxation

Understanding how these brackets work together is crucial for accurate tax calculation. The progressive system means that each bracket's rate applies only to the income within that specific range, not to the entire income amount.

Calculation Methodology:

For any given annual income, tax calculation proceeds systematically through each applicable bracket:

1. First ₦300,000: Always taxed at 7% = ₦21,000
2. Next ₦300,000 (₦300,001-₦600,000): Taxed at 11% = ₦33,000 maximum
3. Next ₦500,000 (₦600,001-₦1,100,000): Taxed at 15% = ₦75,000 maximum
4. Next ₦500,000 (₦1,100,001-₦1,600,000): Taxed at 19% = ₦95,000 maximum
5. Next ₦1,600,000 (₦1,600,001-₦3,200,000): Taxed at 21% = ₦336,000 maximum
6. Next ₦46,800,000 (₦3,200,001-₦50,000,000): Taxed at 24% = ₦11,232,000 maximum
7. Amount above ₦50,000,000: Taxed at 25%

From CRA to Targeted Reliefs

Elimination of Consolidated Relief Allowance

The most significant administrative change in the 2025 tax reforms is the complete elimination of the Consolidated Relief Allowance (CRA), which had been a cornerstone of Nigerian tax relief for decades. The CRA provided a standardized deduction that was applied uniformly regardless of actual expenses or circumstances.

Under the previous system, the CRA offered:

• A fixed percentage of annual income (typically 1% + ₦200,000)
• Universal application regardless of actual expenses
• Simplified administration and calculation
• Limited relevance to actual taxpayer circumstances

Introduction of Rent Relief System

The new system replaces the CRA with a targeted rent relief mechanism that allows taxpayers to claim 20% of their actual annual rent payments, subject to a maximum cap of ₦500,000 per year.

Rent Relief Specifications:

Calculation Method: 20% of actual annual rent paid Maximum Claimable Amount: ₦500,000 per tax year Minimum Documentation Required:

• Valid tenancy agreement
• Proof of rent payments (receipts, bank transfers)
• Landlord identification and tax details where applicable

Rent Relief Scenarios:

Scenario 1: Annual rent of ₦1,200,000

• 20% of ₦1,200,000 = ₦240,000
• Claimable amount: ₦240,000 (within cap)

Scenario 2: Annual rent of ₦3,000,000

• 20% of ₦3,000,000 = ₦600,000
• Claimable amount: ₦500,000 (capped at maximum)

Scenario 3: Annual rent of ₦800,000

• 20% of ₦800,000 = ₦160,000
• Claimable amount: ₦160,000 (within cap)

Documentation Requirements and Compliance

The shift to rent relief necessitates enhanced documentation and record-keeping requirements. Taxpayers must maintain comprehensive records to substantiate their claims:

Primary Documentation:

• Original or certified copies of tenancy agreements
• Complete payment records (bank statements, receipts, transfer confirmations)
• Landlord identification and tax compliance certificates
• Property documentation where applicable

Secondary Documentation:

• Utility bills showing occupancy
• Employment letters confirming work location (for justifying accommodation needs)
• Previous year's tax filings for consistency verification

Impact Analysis of Relief System Changes

The transition from CRA to rent relief has varying impacts across different income levels and circumstances:

Positive Impacts:

• More equitable relief based on actual expenses
• Higher relief for individuals paying substantial rent
• Encouragement of formal rental agreements
• Enhanced tax system transparency

Challenges:

• Increased administrative burden on taxpayers
• Higher documentation requirements
• Potential disputes over acceptable documentation
• Complex verification processes for tax authorities

Enhanced Exemptions and Special Provisions

Compensation for Loss of Employment

One of the most significant enhancements in the 2025 tax reforms is the substantial increase in exemption thresholds for compensation related to loss of employment or personal injury.

Previous Threshold: ₦10,000,000 New 2025 Threshold: ₦50,000,000

This five-fold increase recognizes the economic realities facing Nigerian workers and provides substantial protection for individuals receiving severance payments, redundancy compensation, or personal injury settlements.

Qualifying Compensation Types:

• Severance packages upon termination
• Redundancy payments due to organizational restructuring
• Voluntary separation scheme benefits
• Personal injury compensation settlements
• Wrongful termination settlements
• Early retirement compensation packages

Professional Development and Training Exemptions

The 2025 reforms maintain and in some cases enhance exemptions for professional development expenses, recognizing the importance of continuous learning and skill development in Nigeria's evolving economy.

Qualifying Professional Development Expenses:

• Certification and professional examination fees
• Industry-specific training programs
• Postgraduate education directly related to current employment
• Professional membership dues and subscriptions
• Technical skill development courses
