The Draft Income Tax (Residential Rental Income Tax) Regulations, 2026 represent a major change in enforcement from the Kenya Revenue Authority (KRA). In previous years, compliance with the Monthly Rental Income (MRI) tax was largely a voluntary “honour system.” The 2026 regulations change this by introducing mandatory, automated registration through the Electronic Rental Income Tax System (eRITS).
Furthermore, the Finance Bill 2026 introduces structural adjustments to the tax rates themselves, turning rental management into a tight balancing act.

1. The Core Mechanics: What is Changing?
The eRITS Digital Dragnet
Landlords are required to onboard their properties onto the eRITS platform (integrated via eCitizen). Instead of just reporting a single, lump-sum revenue figure, landlords must now submit:
- Verified property block and plot details.
- Active Tenant KRA PINs and official tenancy agreements.
- A live digital rent roll.
Because eRITS is being fully integrated with Ardhisasa (the Ministry of Lands digital registry), utility company databases, and bank/M-Pesa payment records, KRA can instantly cross-reference your property’s physical existence and land ownership status against the rent you declare.
The Tax Rate Volatility
The regulatory landscape faces fluid changes regarding the rates themselves:
- The Current Regime (Below KSh 15M): If your gross annual residential rental income is between KSh 288,000 and KSh 15 Million, it falls under the simplified residential rental income tax.
- The Proposed Finance Bill 2026 Shift: While the rate was dropped to 7.5% in 2024 to spur compliance, the Finance Bill 2026 proposes reverting the rate back to 10% of gross rental income to close the KSh 83 Billion tax gap.
- The Zero-Deduction Trap: Under this simplified regime, the tax is levied on gross rent collected. You cannot deduct mortgage interest, property management fees, caretakers’ salaries, or maintenance costs.
- The 20th-Day Deadline: Taxes and returns must be filed via eRITS by the 20th day of every subsequent month (e.g., July’s rent must be filed and paid by August 20th). If a tenant defaults, you are still required to file a “Nil” return for that unit to avoid automatic non-compliance penalties.

2. Practical Impact on Nairobi Landlords
Increased Compliance Friction
The administrative load is shifting heavily onto landlords or their property managers. Gathering tenant PINs and keeping an immutable digital rent roll up to date means informal verbal leases are no longer viable.
Additionally, under the parallel Withholding Tax Agent mechanism, corporate tenants or licensed property managers are increasingly being legally mandated to deduct the rental tax at source and remit it directly to KRA, meaning landlords receive their rent net of tax.
High-Leverage Landlords Hit the Hardest
Because the simplified framework explicitly forbids expense deductions, landlords who heavily relied on debt to build or buy apartments face immediate cash flow constraints.
| Financial Profile | Traditional Income Tax Regime (Opt-Out) | Simplified eRITS/RRI Regime |
| Tax Basis | Net Income (Rent minus Expenses) | Gross Income (Total Rent Received) |
| Deduction of Mortgage Interest? | Yes (Only the interest portion) | No |
| Deduction of Maintenance/Repairs? | Yes (With valid ETR/eTIMS receipts) | No |
| Applicable Tax Rates | Graduated scale up to 35% (Individuals) or 30% (Corporate) | 7.5% (Current) / 10% (Proposed 2026 reversion) |
Strategic Note: If you run a highly capital-intensive portfolio with massive mortgage obligations or high operational overhead, the gross tax model cuts deeply into liquidity. Landlords do have the legal right to opt out of the simplified regime to be taxed on net income under standard rates (up to 35%), but you must notify the KRA Commissioner in writing three months before the end of the tax year.
3. Real-World Impact on Nairobi Rental Yields
Nairobi’s historic average gross rental yields have hovered around 5% to 6.5% for residential apartments. The combination of mandatory eRITS enforcement and a potential 10% gross tax rate directly compresses these margins.
Net Yield Compression
Consider a residential flat block generating KSh 500,000 in gross monthly rent, with KSh 150,000 spent on mortgage interest, security, and repairs:
$$Gross\ Monthly\ Income = KSh\ 500,000$$
- Under 7.5% Gross Tax: Tax = KSh 37,500. Take-home after expenses = KSh 312,500.
- Under Proposed 10% Gross Tax: Tax = KSh 50,000. Take-home after expenses = KSh 300,000.
This represents an immediate drop in net yield. For an asset valued at KSh 80 Million, the net yield slides significantly when policy risk is factored in.
Pressure to Pass Costs to Tenants
Landlords will naturally try to protect their margins by pushing rental prices upward. However, Nairobi’s market is highly price-sensitive. In mid-tier residential hubs like Ruiru, Roysambu, and parts of Kilimani, an oversupply of apartments means tenants can easily migrate to competing blocks if a landlord unilaterally jacks up prices to cover tax obligations.
The Shift to Quality and Professional Management
Because individual landlords struggle with monthly digital compliance workflows, there is an accelerating shift toward professional property management firms. These agencies handle the eRITS distributions at scale, though their 5% to 10% management fee adds another layer of cost to the landlord’s bottom line.
