Singapore Rental Income Tax Calculator

The Singapore Rental Income Tax Calculator is a free, browser-based tool that works out the tax payable on rent from an HDB flat or private property. It adds net rental income to your other chargeable income, applies the IRAS progressive resident rates for the Year of Assessment, and isolates the tax attributable to the rental alone.

How Singapore Rental Income Tax Is Calculated

Singapore rental income tax is calculated by adding your net rental income (gross rent minus allowable deductions) to your other chargeable income (employment income, business income, etc.) and applying IRAS progressive personal income tax rates for Year of Assessment 2026. There is no separate rental income tax rate — the income is taxed at your marginal personal rate. Based on IRAS Tax Rates for Resident Individuals 2026.

Key allowable deductions include: mortgage interest (only the interest component — not principal repayments), property tax, fire insurance premiums, cost of repairs and maintenance (not improvements), agent commission fees, management fees for strata properties, and depreciation on furniture and fittings at prescribed IRAS rates. Renovation costs are not deductible as they are capital in nature.

HDB vs Condo Rental Tax — Key Differences

Both HDB flat rental income and private property (condo, landed) rental income are taxed the same way under personal income tax in Singapore. However, there are regulatory differences: HDB flat owners must obtain HDB approval to rent the entire flat (minimum 6 months, occupancy rules apply), while private property owners have more flexibility. From a tax perspective, the IRAS treatment is identical — both must declare rental income and can claim the same categories of allowable expenses.

A common misconception is that HDB rental income is exempt from tax. It is not. IRAS receives annual property transaction data from HDB and URA, so undeclared rental income is detectable. First-time landlords who have been renting without declaring income can make voluntary disclosures to IRAS for a reduced penalty.

Maximising Deductions on Singapore Rental Income

The most frequently missed deductions are: (1) Property tax — often paid as part of GIRO and forgotten at tax time; (2) Furniture and fittings depreciation — IRAS allows depreciation at 1/3 of cost per year for initial 3 years; (3) Mortgage interest — you must separate interest from principal in your loan statements, as only interest is deductible; (4) Agent fees — both the initial letting fee and renewal fees are deductible. Keeping receipts and bank statements is essential for supporting your claims.

This calculator computes your marginal tax rate by first calculating the total tax on all income combined, then subtracting the tax on non-rental income only — giving you the precise tax attributable to your rental income.

Simplified 15% Deemed Expense Claim vs Itemising Actual Costs

Landlords who rent out a residential property in Singapore have two ways to claim expenses, and picking the wrong one costs real money. Under the simplified claim, IRAS lets you deduct a deemed 15% of gross rent for all deductible expenses without keeping a single receipt, and you can still deduct mortgage interest on top. Under the itemised route you claim what you actually spent — property tax, agent commission on renewals, repairs, fire insurance, maintenance fees — but you must keep records for the statutory retention period in case IRAS asks. The rule of thumb: if your non-interest running costs come to less than 15% of gross rent, take the simplified claim and save yourself the paperwork. A tenanted condo grossing S$48,000 a year gets a flat S$7,200 deduction plus interest under the simplified method — a landlord whose real non-interest costs are only S$5,000 is S$2,200 better off doing nothing. Landlords with heavy renovation or high MCST maintenance usually come out ahead itemising. Note the simplified claim covers residential lettings only, so commercial and industrial property must itemise. Confirm the current rules and your Year of Assessment position with IRAS before you file. Updated 2026-08-23.

Non-Resident Landlords and Jointly Owned Property

This calculator assumes you are tax resident in Singapore, which is where most landlords sit — but two situations change the answer enough to matter. If you are a non-resident individual, rental income is not run through the progressive resident bands at all: it is taxed at a flat 24% on net rental income, and none of the personal reliefs (earned income relief, course fees, parent relief) are available to reduce it. That flat rate can be better or worse than resident treatment depending on the amount, so a Singaporean who has moved abroad should compare both before assuming the move saved tax. The current non-resident rates are published by IRAS.

The second situation is joint ownership, which the calculator also does not split for you. IRAS requires each owner to declare rental income and claim deductions in proportion to their legal ownership share, not in whatever split is most tax-efficient. A property held 50/50 by a couple where only one spouse works still puts half the net rent on the non-working spouse's return, where the first S$20,000 of chargeable income is taxed at 0%. To model this, divide the net rental figure by your ownership share before entering it above, and run the calculator once per owner using each person's own other income. Updated 2026-08-31.
