Rental income is not covered by the property tax bill. For Singapore landlords, it is a separate source of income that must be checked and declared to the Inland Revenue Authority of Singapore (IRAS), including when information has already been pre-filled in myTax Portal. The current rules are set out in IRAS’s guide to income from property rented out.
The practical task is to report the right gross rent, choose a permitted expense method and retain the evidence that applies to that choice. This matters for a whole unit, a room rented out in an owner-occupied home and a jointly owned investment property.
What counts as rental income, and when is it taxable?
IRAS says rental income includes the rent for the premises and related payments received for maintenance, furniture and fittings. A forfeited rental deposit is generally part of gross rent. If it was forfeited because the tenant damaged the property, the landlord may claim qualifying rectification costs. Insurance recoveries relating to the rented property and income from subletting are also taxable.
The timing rule can catch landlords who track only bank receipts. Net rental income is taxable when the rent is due and payable, not necessarily when the tenant pays it. For example, rent due in December 2025 but received in January 2026 belongs to the 2025 income period and is reported for Year of Assessment 2026.
Property tax is different: it is an annual tax on property ownership, whether the property is occupied, rented or vacant. Our Singapore property tax guide explains Annual Value and the owner-occupier and non-owner-occupier schedules. Paying that bill does not replace the duty to declare rental income.
Declare the property, ownership share and gross rent correctly
In the Income Tax Return, rental details are reported under Other Income: Rent from property. IRAS requires the gross rent for the previous year, deductible expenses for each property and the taxpayer’s share for jointly owned property.
A sole owner is taxed on 100% of the rental income even if an agent, spouse or another person collects it. For a jointly owned property, income and any rental loss are allocated according to each owner’s legal share, regardless of who receives the cash or funded the purchase. Each co-owner should declare the full rental income and expenses in their own return, then state their percentage share of the net rent based on the legal ownership share.
Pre-filled details are a starting point, not confirmation that the return is correct. IRAS says they may be based on the previous filing or e-Stamping records. A landlord should adjust a wrong rental period or amount and add a property that is missing. This remains important under the No-Filing Service or Direct Notice of Assessment arrangements: pre-filled information still needs to be reviewed.
Choose between deemed and actual rental expenses
For a qualifying tenanted residential property, an individual can generally choose a deemed-expense deduction equal to 15% of gross rent. Allowable mortgage interest on the loan used to buy the tenanted property may be claimed in addition. The 15% method replaces other actual rental expenses; it cannot be stacked with actual property tax, maintenance, insurance or repair claims.
The option has limits. It is not available if no deductible expense apart from mortgage interest was incurred, or if the income came through a Singapore partnership or from property held under a trust. It also does not apply to a non-residential property. If an individual has several tenanted residential properties, the same method – deemed or actual – must be used consistently across all of them for that Year of Assessment. Co-owners, however, may each make their own choice for their respective shares.
Landlords using actual expenses should compare both methods before filing, rather than assuming 15% is always better. The calculation should also sit within a wider assessment of net returns: this guide to whether a condo is suitable for renting out covers vacancy, management costs, financing and other items that gross yield leaves out.
Know which actual costs IRAS allows
The central test is whether an expense was incurred solely to produce rental income and falls within the applicable rental period rules. Common allowable items include interest on the loan used to purchase the tenanted property, property tax, fire insurance, maintenance and repairs that restore the property to its original state. From YA 2022, qualifying agent commission, advertising, legal expenses and stamp duties incurred to obtain, grant, renew or extend a lease for first and subsequent tenants are allowed, subject to IRAS restrictions including certain leases exceeding three years.
During a vacancy between leases, repair, insurance, maintenance, upkeep and property tax may qualify if reasonable efforts were made to find a new tenant. Evidence might include an agent appointment and advertisements. That treatment does not turn private costs or pre-letting improvements into deductions.
Frequent errors include deducting the mortgage principal instead of interest, renovation or improvements instead of repairs, depreciation of furniture, and statutory penalties. A replacement that restores furnishings to their original state may qualify, but a new addition or improvement does not. Utilities or internet paid for a tenant may be deductible only where the tenant does not reimburse the landlord. If only one room is rented out, shared actual expenses must be apportioned; IRAS illustrates this by the number of rooms rented.
Landlords claiming actual expenses must retain supporting records such as tenancy agreements, mortgage statements, invoices and receipts for at least five years. Those using deemed expenses need not keep records for the other rental expenses, but must retain mortgage-interest support for at least five years if claiming that interest.
A simple rental-income example
Consider this illustrative case, which is not an IRAS assessment. A landlord receives S$3,500 a month for a residential unit throughout 2025, making gross rent of S$42,000. The allowable mortgage interest is S$8,000. Under the deemed method, the other expense deduction is S$6,300, or 15% of gross rent. The resulting net rent is S$27,700: S$42,000 less S$8,000 and S$6,300.
If that landlord instead has S$7,400 of substantiated actual allowable expenses excluding interest, the actual-expense calculation produces net rent of S$26,600. On those assumed facts, actual expenses produce the lower net rent. The choice should be made using the landlord’s own records and applied consistently where multiple tenanted residential properties are involved.
A rental deficit cannot reduce employment or other non-rental income and cannot be carried forward. IRAS does allow, as an administrative concession, a rental loss from one property to offset taxable rental income from another property in the same year where all the rented properties were let at market rates.
Correct an omission before it becomes a larger problem
A landlord who spots an error should not wait for an enquiry. Before receiving the tax bill, an online return may generally be re-filed once by 18 April, with all income, expenses, donations and reliefs included again. After the bill arrives, IRAS says the Amend Tax Bill process is available within 30 days of the date on the Notice of Assessment.
For older omissions, the IRAS Voluntary Disclosure Programme may provide reduced penalties where a disclosure is accurate, complete, timely and self-initiated, and the taxpayer cooperates and pays or arranges payment. IRAS states that a qualifying income-tax disclosure within the one-year grace period from the statutory filing deadline attracts no penalty; after that, the reduced penalty is 5% of tax undercharged for each year after the grace period.
The consequences can be much higher outside a qualifying disclosure. IRAS lists, for an incorrect return filed without reasonable excuse or through negligence, a penalty of up to 200% of tax undercharged, a fine of up to S$5,000 and/or imprisonment of up to three years. For wilful tax evasion, its incorrect-return guidance lists a penalty of up to 400%, a fine of up to S$50,000 and/or imprisonment of up to five years.
The safest annual routine is straightforward: reconcile the tenancy agreement against rent due, include related receipts and forfeitures, verify the legal ownership share, compare the two permitted expense methods, and preserve the required records. Where ownership, trust, partnership or expense treatment is uncertain, landlords should check the current IRAS guidance or seek professional tax advice before submitting.
