How Singapore Taxes Rental Income
Rental income in Singapore is taxed under Section 10(1)(f) of the Income Tax Act. It is separate from employment income (Sec 10(1)(b)) and must be declared in your annual tax return. The net rental income (after allowable deductions) is added to your total assessable income and taxed at your marginal personal income tax rate.
Singapore personal income tax rates are progressive: 0% up to $20K, 2% on the next $10K, rising to 24% above $1M. For most landlords earning $120K–$300K combined income, marginal rate on rental income is 11.5%–17%.
What You Can and Cannot Deduct
| Expense | Deductible? | Notes |
|---|---|---|
| Mortgage interest | Yes | Interest portion only NOT principal repayment |
| Property tax | Yes | Annual property tax payable to IRAS |
| Agent commission (leasing) | Yes | Half-month to 1-month fee per tenancy |
| Maintenance and repair | Yes | Must be for upkeep not improvements |
| Furniture depreciation | Yes | Based on asset useful life schedule |
| Insurance (fire/contents) | Yes | Rental property insurance |
| Renovation costs | No | Capital expenditure not revenue deduction |
| Structural improvements | No | Capital in nature |
| Mortgage principal | No | This is capital repayment, not expense |
| Depreciation of building | No | Unlike Australia, no building depreciation in SG |
Rental Loss Example
| Item | Monthly | Annual |
|---|---|---|
| Gross rental income | $2,500 | $30,000 |
| Less: Mortgage interest (on $900K loan at 1.6%) | −$1,200 | −$14,400 |
| Less: Property tax (10% AV ~$24K) | −$200 | −$2,400 |
| Less: Agent fee (half-month, amortised) | −$104 | −$1,250 |
| Less: Maintenance and repairs | −$100 | −$1,200 |
| Net rental income (loss) | −$104 | −$1,250 |
In this scenario, you have a $1,250 rental loss for the year. Under IRAS rules:
- If you have another rental property earning $5,000 net you can offset: net rental income = $5,000 − $1,250 = $3,750 taxable
- If you have no other rental income the $1,250 loss is carried forward to future years when you do have rental income
- You cannot deduct the $1,250 from your employment income
Loss Carry-Forward Rules
Rental losses under Sec 10(1)(f) can be carried forward indefinitely. There is no time limit you can accumulate rental losses over many years and offset them against future rental income when the property becomes profitable (e.g., after the loan is repaid and interest expense drops).
Importantly, if you sell the property, any unabsorbed rental loss carry-forward is lost you cannot use it against capital gain (Singapore has no capital gains tax anyway) or convert it into any other deduction.
The Singapore vs Australia Difference
| Singapore | Australia | |
|---|---|---|
| Rental loss offset against salary | No | Yes (negative gearing) |
| Rental loss carry-forward | Yes, indefinitely | Yes |
| Building depreciation | No | Yes (capital works) |
| Capital gains tax on sale | No CGT | Yes (50% discount if held 1yr+) |
| Mortgage interest deductible | Yes (interest only) | Yes (interest only) |
Tax Planning Implication
Because you cannot offset rental losses against employment income, the tax benefit of running a property at a loss in Singapore is limited compared to Australia. The primary financial benefit of a Singapore rental property loss is deferral you are building a loss carry-forward that will shelter future rental income once the property becomes cash flow positive (typically when the loan is substantially repaid or rental income rises).

Rental Income Tax by Marginal Rate: Real Examples
| Combined Annual Income (incl. rental) | Marginal Rate on Rental Income | Tax on $20K Net Rental Income | After-Tax Rental Income |
|---|---|---|---|
| $80,000 total | 7% | $1,400 | $18,600 |
| $120,000 total | 11.5% | $2,300 | $17,700 |
| $160,000 total | 15% | $3,000 | $17,000 |
| $200,000 total | 18% | $3,600 | $16,400 |
| $320,000 total | 22% | $4,400 | $15,600 |
Marginal rates are approximate based on YA 2026 tax bands. Actual tax depends on all deductions, reliefs, and rebates. High-income landlords should consider whether to hold rental property in a spouse's name if their marginal rate is significantly lower.
Common Mistakes Singapore Landlords Make on Tax
- Claiming renovation costs as repairs. Renovation (capital expenditure) is not deductible. Repairs and maintenance (restoring to original condition) are deductible. Painting walls after a tenant leaves = deductible. Installing a new kitchen = capital expenditure, not deductible.
- Deducting mortgage principal repayment. Only the interest portion of your loan instalment is deductible. Principal repayment is a capital item it is your own money repaying your own loan, not a business expense.
- Forgetting to declare rental income for part-year tenancies. Even a single month of rental income must be declared. IRAS cross-references tenancy agreements and utility transfers. Under-declaration attracts penalties of up to 200% of tax undercharged.
- Claiming deductions for a property used partly for personal use. If you occupy part of the property yourself and rent out the rest, deductions must be apportioned on a floor-area basis. You cannot claim 100% of the mortgage interest if you are living in one bedroom and renting the other.
Frequently Asked Questions
How long can I carry forward an unabsorbed rental loss in Singapore?
IRAS allows rental losses under Section 10(1)(f) to be carried forward indefinitely there is no time limit. You can accumulate losses over many years and use them against future rental income when the property eventually turns cash-flow positive. However, if you sell the property, any remaining unabsorbed loss is permanently extinguished it cannot be applied against the sale proceeds or any other income.
Can I deduct interest on a personal loan used to fund my rental property purchase?
Only if the loan is directly secured against the rental property or can be clearly traced to the property acquisition. A general personal loan (not secured against the property) used to fund part of the purchase is unlikely to be accepted by IRAS as a deductible interest expense. The loan must have a clear nexus to the income-producing asset.
What is the deemed rental income rule for HDB flats?
There is no deemed rental income rule for HDB flats in Singapore you are only taxed on actual rent received. Unlike some jurisdictions where owner-occupiers are taxed on imputed rental income, Singapore does not apply this concept. You pay property tax on the Annual Value (AV) regardless of whether you rent or occupy, but income tax on rental income only applies when rent is actually received.
