What Rental Expenses Can Landlords Deduct in Singapore?
A practical IRAS-grounded guide to common deductible items, repair vs renovation, records to keep, and the mistakes landlords often make.
Singapore landlords can usually deduct expenses directly tied to earning rental income and revenue in nature, such as property tax, mortgage interest, fire insurance, repairs and maintenance, and the cost of renewing a tenancy (including renewal agent commission). Personal costs, loan principal, purchase costs, and capital improvements are usually not deductible. Alternatively, as of 2026 an individual landlord may claim a deemed rental expense of 15% of gross rent instead of actual expenses and still deduct mortgage interest, applied consistently across all their tenanted homes. The safest approach is to keep invoices, payment proof, and tenancy records, then verify grey areas against current IRAS guidance before filing.
For Singapore landlords, the core rule is simple: an expense is more likely to be deductible if it was incurred to produce rental income and is not personal or capital in nature. The challenge is in the details. Many filing mistakes come from treating repairs like renovations, or assuming every property-related bill can be claimed. This guide gives you a clear way to understand what is commonly deductible, what is often misclassified, and what to document before filing.
What does "deductible against rental income" mean for Singapore landlords?
A rental expense is generally deductible only if it was incurred to earn rental income and is not personal or capital in nature. The practical test is whether the cost supports the rental activity rather than the owner's personal use or a long-term upgrade.
It means the expense must be incurred to produce rental income, and it should not be personal or capital in nature. In practical terms, the cost should relate to earning rent or keeping the unit rentable, not to the landlord's own living needs or to a long-term asset upgrade.
The clearest official starting point is IRAS's guidance on income from property rented out. The most useful way to hold the rule is this:
- If the cost helps you earn rent, it may be deductible
- If it is personal, private, or owner-use related, it usually is not
- If it upgrades, extends, or materially improves the property, it is usually not treated the same way as a routine rental expense
Insight line: "Rental deductions are about earning the rent, not improving the asset."
That one distinction is why a leaking tap repair and a full kitchen remodel should not be treated the same way in a tax filing. For a broader overview, see Singapore Property Tax and Ownership Costs.
Which common rental expenses are usually deductible?
Common deductible rental expenses usually include property tax, the interest portion of a rental loan, repairs, maintenance, turnover cleaning, and tenant-finding costs. These are the routine costs most clearly tied to earning rent.
The everyday items landlords most often claim are property tax, mortgage interest, fire insurance, repair and maintenance costs, and tenant-finding costs. These are the categories most clearly tied to earning rent under IRAS treatment.
Common deductible examples include:
- Property tax for the rented property
- Interest on the loan used to buy the rented property (the interest portion, not principal repayment)
- Fire insurance premiums on the property
- Condo maintenance-related charges linked to the rented unit
- Minor repairs and upkeep work
- Air-con servicing, pest control, and similar recurring maintenance
- Cleaning between tenancies
- Cost of renewing a tenancy, including the leasing commission to secure a new tenant on renewal
One key distinction on tenant-finding costs: the commission and marketing cost to secure a subsequent or renewal tenant is generally deductible, but the expense of securing the very first tenant for a property is not. For a private condo landlord, a typical claim set may include property tax, fire insurance, routine servicing, a plumber's invoice for a leak, and leasing commission for a renewal tenant. For an HDB room-rental case, the issues are often smaller but trickier: shared utilities, mixed-use costs, and partial-use allocation matter more.

For a non-official but useful professional summary, BDO's overview of rental taxation can help you sense-check the common categories before going back to IRAS.
Which expenses are commonly confused with deductible rental costs but may not qualify?
The main non-deductible traps are personal costs, loan principal, purchase costs, and capital improvements dressed up as repairs. If the expense improves the asset or serves the owner personally, it usually should not be treated as a routine rental deduction.
The biggest mistakes usually come from claiming costs that are property-related but not rental-operating expenses. A bill can be connected to the property and still not be deductible against rental income.
Items commonly misclassified include:
- The owner's personal living expenses
- Owner-use expenses for a partly self-occupied property
- The principal portion of a loan repayment
- Stamp duty and other purchase-related costs
- Legal fees for buying the property
- Major renovations, additions, or redesign works
A useful way to see it: "If the expense buys the asset, improves the asset, or serves your personal use, it is usually not the same as maintaining the property for rental."
This is also why it pays to be careful with words like "renovation" and "repair." It is easy to use them interchangeably, but IRAS does not. If the invoice shows a full makeover, layout change, or built-in upgrade, do not assume it belongs in the same bucket as a leaking pipe repair.
IRAS's general approach to deductible expenses is also consistent with the broader distinction it makes in business expenses and deductions: purpose and nature matter, not just whether money was spent. For a broader overview, see Property Tax When You Rent Out Your Flat or Condo.
How should landlords treat repairs, replacements, and renovations?
Repairs usually restore function, while renovations and upgrades usually improve or change the asset. Replacements are the grey zone, so detailed invoices and a quick classification check matter before filing.
This is the classification issue that causes the most confusion. Repairs usually restore the property to working condition. Renovations and improvements usually change, upgrade, or materially improve the asset. Replacements can sit in the middle, so the invoice detail matters.
A simple working comparison is:
| Type of cost | Typical example | What to remember |
|---|---|---|
| Repair or maintenance | Fixing a leak, patching a damaged wall, repainting due to wear and tear, servicing the air-con | Usually easier to support as a revenue expense tied to keeping the unit rentable |
| Replacement | Replacing a faulty appliance or fitting with a similar one | Can be a grey area; keep detailed invoices and verify treatment if the amount is meaningful |
| Renovation or improvement | Full kitchen overhaul, new built-ins, layout change, major redesign | Usually closer to capital expenditure than a routine rental deduction |
Realistic examples:
- Repainting because the previous tenancy caused wear and tear is easier to explain as maintenance
- Repainting as part of a full unit refresh before repositioning the property may need closer review
- Servicing an existing air-con is maintenance
- Replacing a broken tap with a similar tap is usually easier to justify than replacing the whole kitchen line with upgraded fittings
- Installing built-in carpentry to improve marketability is usually not the same as repairing damage
Insight line: "Repair keeps the unit working; improvement makes the unit different."
If your instinct is "I only replaced what was old," ask yourself two questions first: Was it like-for-like, and did it materially upgrade the property? Those two questions usually surface whether the item is straightforward or a grey area. For a broader overview, see What Are MCST Fees in Singapore and What Do They Cover?.
What records should landlords keep for each deductible expense?
Keep invoices, receipts, payment proof, tenancy records, and supporting notes that show what the expense was for and which rental period it relates to. The strongest record set links the cost clearly to the rented unit and the tenancy timeline.
Landlords should keep enough evidence to show three things: what was paid, when it was paid, and why it was incurred. If the expense cannot be tied back to the rented property and tenancy period, it becomes much harder to support.
A practical rental file should include:
- Invoices and receipts
- Bank transfer records, card statements, or other payment proof
- Work orders, contractor quotations, and service contracts
- Tenancy agreements, renewals, and handover dates
- Property tax notices and loan interest statements
- Agent commission invoices and marketing invoices
- Photos before and after repair work, where useful
- Notes explaining mixed-use splits or unusual items
The most useful habit is this: file records by property and by tenancy period, not just by calendar year. With two units and multiple short tenancies, it is easy to lose track if all receipts sit in one folder.
Example: an air-con servicing invoice, a plumber's transfer screenshot, and a lease renewal date already give you a much cleaner audit trail than a single bank statement line saying "home repairs".
If condo charges are part of the picture, internal explainers such as What Are MCST Fees in Singapore and What Do They Cover? can help separate routine maintenance-related charges from other condo fund concepts that may need closer review.
What are the expenses landlords most often forget to document?
Small recurring costs are the easiest to miss, especially servicing, pest control, cleaning, and minor repairs. These often add up more than landlords expect, so under-documentation is a common filing mistake.
The items most often missed are the small, recurring costs that feel too minor to matter at the time. In practice, these are the deductions landlords under-document most often, not the major renovation bills.
The usual misses are:
- Minor handyman or repair jobs
- Air-con servicing
- Pest control
- Turnover cleaning after a tenant moves out
- Tenant-placement commissions
- Recurring maintenance-related charges
A common real-world scenario: the landlord remembers the leasing commission and the big repainting bill, but forgets three separate small plumbing visits, one pest control callout, and two air-con servicing invoices booked over WhatsApp. Individually they look small; across a year they can materially change the net rental figure.
Insight line: "Landlords usually overremember big works and underrecord routine upkeep."
The takeaway is simple: keep every receipt linked to keeping the unit rentable, not just the headline invoices.
How do mixed-use or partly personal expenses work?
For mixed-use costs, only the rental portion should be claimed. The split should be reasonable, consistent, and backed by a simple written basis such as area used, period rented, or actual usage.
Only the rental-use portion should be claimed, and the split should be reasonable, consistent, and recorded. This matters most when only part of the property is rented out or when one expense serves both rental and personal use.
Typical scenarios include:
- A room is rented out while the owner continues living in the rest of the flat
- Utilities or internet are shared across owner-use and tenant-use areas
- A phone plan is used partly for tenant communication and partly for personal matters
- Maintenance costs relate to a property that is not fully tenanted for the whole year
The simplest way to see it: "Claim only the part that supports the rental activity."
Questions to ask yourself:
- What part of the property was actually rented out?
- Was the expense for the whole home or only the rented area?
- How did you decide the split?
- Is the same basis used consistently across similar items?
A rough allocation note is better than no note. If the claim is material, document the basis before filing rather than trying to reconstruct the logic months later.
When should a landlord verify treatment with IRAS or a tax professional?
Large, unusual, mixed-use, renovation-linked, vacancy-related, or simplified-method claims should be verified before filing. This is where it is worth checking current IRAS guidance or a qualified tax professional instead of guessing.
Verify before filing when the expense is large, unusual, mixed-use, linked to renovations, or incurred during a vacancy or transition period. Those are the situations where it is worth stopping short of a confident yes-or-no answer.
This is also important if you want to use the simplified expense method instead of tracking actual costs. As of 2026, IRAS lets an individual who rents out residential property claim a deemed rental expense of 15% of gross rent in place of actual deductible expenses — and you can still separately deduct mortgage interest on top of the 15%. If chosen, the 15% basis must be applied consistently across all of that individual's tenanted residential properties for the year, not mixed with actual-cost claims property by property. IRAS sets this out in its e-Tax guide on the simplification of claim of rental expenses for individuals; confirm the latest version and current applicability before relying on it. For how this fits the overall rental-income calculation, see How Rental Income Is Taxed in Singapore.
Practical rule: if you cannot clearly explain why the cost is a routine rental expense, treat it as a verification item, not a quick messaging answer.
What should a landlord prepare before filing rental income deductions?
Before filing, landlords should gather tenancy records, rent logs, expense invoices, payment proof, property tax and loan documents, and notes for any mixed-use or grey-area claims. A clean file reduces both underclaiming and overclaiming risk.
- ✓Tenancy agreements, renewal letters, and key handover dates
- ✓Rent ledger or rental collection records
- ✓Invoices and receipts for repairs, servicing, cleaning, pest control, and maintenance
- ✓Proof of payment such as bank transfer records, statements, or card charges
- ✓Property tax notices for the rented property
- ✓Loan statements showing the interest portion, where relevant
- ✓Agent commission invoices and tenant-marketing costs
- ✓Contractor quotations, work orders, and service reports
- ✓Photos for material repair works, where available
- ✓Notes on any mixed-use allocation and how the split was determined
- ✓A separate folder for any grey-area items that may need IRAS or tax-professional verification
