Maximize Tax Deductions Real Estate Investments Nigeria 2026: Mortgage Maintenance Depreciation Solar
With the Finance Act 2025 amendments and ongoing CBN rate cuts, real estate investors can now claim more deductions in 2026 than ever before. Many still miss out on ₦1M–₦10M+ annual tax savings due to poor record-keeping or lack of awareness.
The key areas with the biggest potential savings are mortgage interest (for individuals and companies), property maintenance and repairs, capital allowances/depreciation on commercial buildings, and enhanced reliefs for green/solar installations.
1. Mortgage Interest Deduction Individuals can deduct mortgage interest paid on loans used to acquire residential property (up to a cap under PITA). Companies can claim full interest as a business expense under CITA.
- 2026 limit for individuals: Up to ₦5 million per year (increased from previous caps)
- Example: ₦80M mortgage at 18% interest → annual interest ~₦14.4M. Individual can claim up to ₦5M deduction → tax savings of ₦1.5M–₦2M (depending on tax bracket).
2. Property Maintenance & Repairs Both individuals and companies can deduct actual expenses for repairs and maintenance of investment properties.
- Allowable: Routine repairs, painting, plumbing, electrical fixes, minor structural work
- Not allowable: Major improvements or capital additions (these qualify for capital allowances)
- 2026 tip: Keep detailed invoices and photos. Average annual claim for a ₦30M rental property: ₦800k–₦2M → tax savings ₦240k–₦600k.
3. Depreciation / Capital Allowances on Commercial Buildings Companies can claim capital allowances on commercial properties (offices, shops, warehouses).
- Initial allowance: 10% in year 1
- Annual allowance: 2% per year thereafter (straight-line)
- Example: ₦200M commercial building → Year 1 allowance ₦20M → tax savings ₦6M (at 30% CIT). Over 10 years total relief can exceed ₦60M.
4. Green & Solar Installation Reliefs The biggest new opportunity in 2026. Solar PV systems, inverters, and energy-efficient upgrades qualify for enhanced capital allowances and possible investment tax credits under the green incentives framework.
- Capital allowance: Up to 90% initial allowance on solar/renewable equipment
- VAT exemption: Still applies on solar panels and related components
- Example: ₦12M solar system installed on a ₦150M commercial property → Year 1 allowance ₦10.8M → tax savings ₦3.24M (30% CIT). Plus monthly electricity bill savings of ₦300k–₦600k.
Documentation Requirements (FIRS 2026 Rules)
- Keep receipts/invoices with clear description
- Maintain a property expense ledger (Excel or accounting software)
- For green installations: NGBC or certified installer report + photos
- For mortgage interest: Bank statement showing interest paid + loan agreement
- Submit with annual tax return (self-assessment due March 31 for individuals, 6 months after year-end for companies)
Real 2025–2026 Investor Examples
- Investor A (Lagos): ₦45M rental property + ₦8M solar retrofit → claimed ₦3.2M maintenance + ₦7.2M green allowance → saved ₦3.1M in tax.
- Investor B (Abuja): ₦120M commercial building → claimed ₦12M initial allowance + ₦2.5M repairs → saved ₦4.35M.
- Investor C (diaspora): ₦65M mortgage → claimed ₦4.8M interest deduction → saved ₦1.44M.
Final Thoughts
In 2026, tax deductions are one of the most powerful (and under-used) tools for boosting real estate returns.
By claiming mortgage interest, maintenance costs, depreciation, and especially green/solar reliefs, many investors are quietly adding ₦1M–₦10M+ to their bottom line every year.
The key is meticulous record-keeping and early planning. Start building your deduction file today — it will pay off at tax time.
