Rental Income Tax Guide for Singapore Landlords

Updated May 2026 | PSF Insight

Rental income from Singapore residential property is taxable, but most landlords leave money on the table by mishandling deductions. Understanding the 15% deemed expense rule, the deductibility of mortgage interest, and the differences between resident and non-resident treatment can save several thousand dollars in tax each year. This guide covers everything Singapore landlords need to know to file accurately.

Who Pays Tax on Singapore Rental Income

Any individual or entity earning rental income from Singapore property is subject to tax, regardless of residency. The rate and deduction rules differ:

Tax residency for individuals generally requires physical presence or work in Singapore for at least 183 days in the calendar year. Many overseas-based Singapore Citizens fall under non-resident treatment when filing rental income.

The 15% Deemed Expense Rule

Since 2010, IRAS has offered individual landlords a simplified deduction option for residential rental income. Instead of tracking actual operating expenses, you can claim a flat 15% of gross rent as deemed expenses, plus mortgage interest separately.

How It Works

For a property generating SGD 4,500 monthly rent (SGD 54,000 annually) with SGD 18,000 in mortgage interest:

If your marginal tax rate is 15%, tax payable on this rental is SGD 4,185. The 15% deemed amount covers items such as utilities, repairs, insurance, property tax, and agent commissions, all of which would otherwise need receipts and detailed records.

When the 15% Option Saves You Money

The deemed option is most beneficial when your actual expenses (excluding mortgage interest) fall below 15% of gross rent, which is common for new condos with low maintenance needs. For example, a recently TOP'd condo may have actual expenses of SGD 4,000 to SGD 6,000 against rent of SGD 54,000, well below the SGD 8,100 deemed amount.

When to Skip the Deemed Option

Older properties with high repair costs, vacant periods, or major one-off expenses may exceed 15% in a given year. In those cases, claiming actual expenses with proper documentation can produce a lower tax bill.

Allowable Actual Deductions

If you choose actual deductions instead of the 15% deemed amount, the following are claimable:

Property Operating Costs

Repairs and Maintenance

Letting Costs

Mortgage Interest

Always deductible regardless of whether you claim 15% deemed or actual expenses. Only the interest portion of the mortgage is deductible; the principal repayment is not.

What Is Not Deductible

Capital expenses and improvements are not deductible against rental income. These include:

Improvements add to the property's cost base for any future capital gain consideration but do not reduce current year rental tax.

Filing Deadlines and Process

Rental income is reported as part of the annual personal income tax return. Key dates:

For couples who jointly own a rental property, each spouse declares their proportional share. The default split is by legal ownership percentage on the title, but actual rental contribution from each spouse can be relevant if challenged.

Rules for Non-Resident Landlords

Non-residents face the flat 24% rate but the same deduction rules. Key differences:

Withholding Tax Considerations

Although there is no statutory withholding by tenants in standard residential tenancies, certain managed structures and corporate tenants do operate withholding arrangements. Non-resident landlords should clarify obligations with their property manager.

Filing Requirements

Non-residents must still file annually if they have Singapore-source rental income. IRAS issues a tax bill based on filed returns and can backdate assessments for unfiled years with penalties.

Singapore Citizens Living Abroad

SCs working overseas often qualify as non-residents if absent from Singapore for sustained periods. Even a small rental income may push the global tax position into a less favourable bracket once the 24% flat rate applies.

Common Mistakes Landlords Make

A Quick Decision Framework

Each February, run a quick check before filing:

  1. Total your gross rent received during the calendar year
  2. Calculate 15% of gross rent as the deemed amount
  3. Total your actual non-mortgage expenses with receipts
  4. Use whichever is higher in your tax filing
  5. Add mortgage interest separately in either case

Most modern condo landlords find the 15% deemed amount slightly higher than actual expenses, making it the default choice for simplicity. Always retain records for at least 5 years in case of an IRAS query.
