Rental Income Tax Exemptions in Kenya: What Landlords Can Deduct

"Can I deduct my mortgage from rental income tax?"
This is one of the most common questions from Kenyan landlords. And the answer isn't straightforward.
It depends on which tax system you're under.
Let me explain your options — and when deductions make sense.

Two Tax Systems for Rental Income
Residential rent in Kenya is taxed one of two ways:
1. MRI (Monthly Rental Income) Tax
- For residential rent between KES 288,000 and KES 15 million a year
- Flat 7.5% of gross rent
- No deductions allowed
- Monthly filing, and it's a final tax
2. Regular Income Tax
- For commercial rent, rent outside that band, and anyone who elects out of MRI
- Graduated rates from 10% to 35%
- Deductions allowed
- Declared in your annual return
MRI is the default for residential rent inside the band. This article is about the deductions you get under regular tax, and when that's actually worth leaving MRI for. (Short answer: less often than people think.)

MRI Tax: No Deductions
Let's be clear: under MRI, you cannot deduct anything.
Not mortgage interest. Not repairs. Not management fees. Nothing.
The 7.5% applies to your gross rental income — every shilling collected.
Example under MRI:
- Monthly rent: KES 500,000
- Mortgage interest: KES 150,000
- Repairs: KES 30,000
- Management fee: KES 50,000
- Taxable income: KES 500,000 (expenses ignored)
- Tax: KES 500,000 × 7.5% = KES 37,500
Your KES 230,000 in expenses doesn't reduce your tax bill at all.
For some landlords, this is fine — the simplicity is worth it. For others, it's expensive.

Regular Income Tax: Deductions Allowed
Under the regular income tax system, you can deduct qualifying expenses from your rental income. You pay tax only on the profit.
Example under Regular Tax:
- Monthly rent: KES 500,000
- Mortgage interest: KES 150,000
- Repairs: KES 30,000
- Management fee: KES 50,000
- Taxable income: KES 500,000 - 230,000 = KES 270,000
- Tax: ~KES 30,000-40,000 (depending on other income and rates)
Same rental income, but potentially lower tax — because expenses reduce your taxable amount.

Allowable Deductions (Regular Tax System)
Here's what KRA allows you to deduct:
1. Mortgage Interest
The interest portion of your mortgage payment is deductible. Not the principal — just the interest.
Early in your mortgage, this is significant (interest-heavy payments). Later, less so.
How to calculate: Your bank provides annual interest certificates. Use those figures.
2. Repairs and Maintenance
Costs to maintain the property's current condition:
- Plumbing repairs
- Electrical fixes
- Painting (maintenance, not improvement)
- Roof repairs
- Appliance repairs
Not included: Improvements that add value (new bathroom, extra room). Those are capital expenses, not deductible repairs.
3. Property Management Fees
If you hire a property manager or agent:
- Management fees (typically 5-10% of rent)
- Letting fees for finding tenants
- Administration charges
Keep invoices from your management company.
4. Insurance Premiums
Property insurance protecting against:
- Fire
- Theft
- Natural disasters
- Liability
The full premium is deductible.
5. Legal and Professional Fees
Fees related to rental income:
- Lease agreement preparation
- Tenant dispute resolution
- Accountant fees for rental income
- Property valuation (for rental purposes)
6. Bad Debts
Rent you invoiced but couldn't collect — and have given up on — may be deductible.
Requirements:
- You must have made reasonable collection efforts
- The debt must be genuinely irrecoverable
- Keep documentation of collection attempts
7. Service Charge and Ground Rent
If you pay service charge to a management company (for common areas, security, etc.), it's deductible.
Ground rent on leasehold properties also qualifies.
8. Agent Commissions
One-time commissions paid to agents for:
- Finding tenants
- Lease renewals
The full commission amount is deductible in the year paid.
9. Advertising Costs
Costs to advertise vacant units:
- Property listing sites
- Newspaper ads
- Social media advertising
10. Utilities (If Included in Rent)
If you provide utilities and include them in rent:
- Water
- Electricity
- Internet
You can deduct these costs.
Note: If tenants pay utilities separately, this doesn't apply.

What You CANNOT Deduct
Some common misconceptions:
1. Principal mortgage payments Only interest qualifies. Paying down principal is building equity, not an expense.
2. Capital improvements Adding a new bedroom, installing solar panels, building a wall — these add value. They're not deductible as expenses (though they may reduce capital gains tax if you sell).
3. Personal expenses Anything unrelated to the rental property.
4. Your own labour You can't pay yourself for repairs and deduct it.
5. Penalties and fines KRA penalties, council fines, etc. are not deductible.
When to Choose Regular Tax Over MRI
Here's the calculation:
MRI: 7.5% of gross rent Regular tax: graduated rates on (rent minus expenses), minus personal relief
The catch is the graduated rates. Profit above KES 388,000 a year is taxed at 30%, and higher still past KES 6 million. So regular tax has to knock out a lot of profit before it beats a flat 7.5% of gross.
Example Comparison
Both landlords collect KES 400,000 a month (KES 4.8 million a year), and rent is their only income, so the personal relief of KES 28,800 applies.
Landlord A: low expenses (15%)
- Expenses: KES 60,000 a month
- MRI: KES 400,000 × 7.5% = KES 30,000 a month
- Regular tax on KES 4.08 million of profit: about KES 94,400 a month
Verdict: MRI, by a mile.
Landlord B: high expenses (45%)
- Expenses: KES 180,000 a month
- MRI: KES 30,000 a month
- Regular tax on KES 2.64 million of profit: about KES 58,400 a month
Verdict: still MRI, by about KES 28,000 a month.
At this rent, regular tax only starts to win once expenses pass roughly 70% of rent. That's a heavily mortgaged property, not a well-run block with normal costs.
Regular tax tends to win when:
- Rent is small and is your only income
- A large mortgage eats most of the rent
- You had an unusual year of major repairs
MRI almost always wins when:
- You also earn a salary. Your salary already uses the lower bands and your relief, so rent profit would be taxed at your top rate
- Expenses are a normal share of rent

How to Leave MRI for Regular Tax
The Residential Rental Income Tax Regulations set the rules:
- Notify KRA in writing at least three months before the end of your year of income. For most individuals that's the calendar year, so by the end of September.
- It takes effect the following year, not straight away.
- KRA should acknowledge within 60 days. If it doesn't, your notice is treated as received.
- From then on, your rent goes in your annual return, with your expenses deducted.
Keeping Records for Deductions
If you claim deductions, KRA can audit you. Keep these records:
For mortgage interest:
- Loan agreement
- Bank statements
- Annual interest certificate from bank
For repairs:
- Invoices from contractors
- Receipts for materials
- Photos (before/after)
- Description of work done
For management fees:
- Management agreement
- Monthly/annual invoices
- Payment receipts
For insurance:
- Policy documents
- Premium receipts
For everything:
- Keep records for 5 years
- Digital copies are acceptable
- Organize by year and category

Using Software to Track Expenses
Tracking deductions manually is tedious. Property management software helps by:
- Recording expenses as they occur
- Categorizing by type
- Attaching receipts/invoices
- Generating annual expense summaries
- Calculating net income automatically
When tax time comes, export your report and hand it to your accountant.
Should You Get a Tax Advisor?
Consider professional help if:
- Your rental income exceeds KES 5,000,000/year
- You have multiple properties
- You're unsure which system is better
- You have complex deductions (large mortgage, many repairs)
Get a quote first, and weigh it against what the comparison above says you'd actually save.
Key Takeaways
- MRI = simple but no deductions — 7.5% on gross rent
- Regular tax = complex but flexible — Deductions reduce taxable income
- Regular tax wins less often than people think. At KES 400,000 a month it takes about 70% expenses
- Keep detailed records — Deductions require proof
- Consult an advisor for large portfolios — Optimization pays off
Most landlords are better off on MRI, even with real expenses. Run both numbers before September if you think you're the exception.
