Understanding Mortgage Duty, Owner-Occupied vs Landlord Property Tax in Singapore 2026 — IRAS Progressive Rates, Annual Value & How to Save Thousands
You paid the stamp duty when you bought your property. You thought you were done with IRAS. Then, every January, a property tax bill arrives — and the amount depends entirely on whether you live in the property or rent it out. Meanwhile, if you took a mortgage, there was a one-time mortgage duty that most buyers only notice as a line item on their conveyancing lawyer invoice. This guide explains all three, with real dollar examples and free calculators so you never get surprised by an IRAS bill again.
Understanding Mortgage Duty in Singapore 2026 — The One-Time Fee Your Conveyancing Lawyer Charges That Most Buyers Overlook
Mortgage duty is a stamp duty charged on your mortgage instrument — the legal document that secures your property as collateral for the loan. Every time you take out a new mortgage, refinance to a different bank, or execute a supplemental mortgage document, mortgage duty applies. The rate is 0.4% of the loan amount, capped at a maximum of S$500.
Yes, you read that right — the maximum is S$500 regardless of how large your mortgage is. Whether you borrow S$200,000 for an HDB flat or S$5 million for a Good Class Bungalow, the most you will ever pay in mortgage duty is S$500. For most homeowners, this means the actual calculation is irrelevant because the cap kicks in at loan amounts above S$125,000 (since 0.4% of S$125,000 = S$500). Almost every property loan in Singapore exceeds S$125,000, so effectively, mortgage duty is a flat S$500 fee.
This might seem trivial compared to the hundreds of thousands you pay in BSD and ABSD. But there is a catch that most people do not realise: mortgage duty applies every time you refinance. If you refinance your mortgage every 3 years (which many Singaporeans do to lock in lower SORA rates), you pay S$500 each time. Over 25 years, that is 8 refinancing events and S$4,000 in mortgage duty alone. Not a deal-breaker, but something to factor into your refinancing savings calculation.
Understanding Owner-Occupied Property Tax in Singapore 2026 — IRAS Progressive Rates Based on Annual Value for Your Own Home
Property tax in Singapore is not based on your property price or what you paid for it. It is based on the Annual Value (AV) — which is the estimated annual rent your property could fetch if it were rented out, as determined by IRAS. Even if you live in your own home and have no intention of renting it out, IRAS assigns an AV based on comparable rental transactions in your area.
For owner-occupied residential properties, Singapore uses progressive tax rates that increase as the AV rises. The first S$8,000 of AV is tax-free — which means owners of very modest properties (typically 1-2 room HDB flats) pay zero property tax. The next S$47,000 is taxed at rates from 4% to 6%, and the portion above S$55,000 is taxed at 10% to 32% in a series of brackets.
Here is what this looks like in practice: a 4-room HDB flat in Tampines with an AV of S$15,600 pays approximately S$456 in annual property tax. A 5-room HDB in Bishan with an AV of S$19,200 pays about S$612. A private condo in Queenstown with an AV of S$36,000 pays around S$1,720. And a semi-detached house in Bukit Timah with an AV of S$84,000 pays approximately S$11,880. The jump between HDB and private property is where the tax starts to bite.
How IRAS Determines Your Annual Value and Why It Changes Every Year
IRAS reviews Annual Values every year based on market rental data. If rental prices in your area increase (as they did significantly in 2023-2024), your AV goes up and so does your property tax. You can check your current AV and property tax payable on the IRAS myTax Portal. If you believe your AV is too high compared to actual rental transactions in your neighbourhood, you can file an objection with IRAS within 30 days of receiving your notice of assessment.
Use the Owner-Occupied Property Tax Calculator to compute your exact tax for any AV amount. It applies the full progressive rate table and shows you both the total tax and the effective rate.
Understanding Non-Owner-Occupied (Landlord) Property Tax in Singapore 2026 — Why Renting Out Your Property Costs Significantly More in Tax
The moment you rent out your property — whether fully or partially — it is reclassified as non-owner-occupied for property tax purposes. The tax rates for non-owner-occupied properties are significantly higher than owner-occupied rates because the Singapore government uses the tax differential as a policy tool to discourage property hoarding and encourage owner-occupation.
Non-owner-occupied rates start at 12% for the first S$30,000 of AV and go up to 36% for AV above S$90,000. There is no tax-free threshold — every dollar of AV is taxed. For the same 5-room HDB in Bishan with an AV of S$19,200, the property tax jumps from S$612 (owner-occupied) to S$2,304 (non-owner-occupied). That is a S$1,692 increase — or 276% more tax — just because you rented it out instead of living in it.
This tax differential is one of the most important but least discussed factors in Singapore property investment. Many first-time landlords do the rental yield calculation based on gross rent minus mortgage payment, forgetting to account for the substantially higher property tax. On an investment condo with an AV of S$48,000, the annual property tax as a landlord is approximately S$7,080 versus S$2,520 if you lived in it. That S$4,560 difference directly reduces your net rental yield by about 0.3% to 0.5% on a S$1 million property.
How These 3 Property Tax Calculators Work — IRAS-Accurate Mortgage Duty, Owner-Occupied and Landlord Tax Computation
The Mortgage Duty Calculator takes your loan amount and computes 0.4% with the S$500 cap applied automatically. It also shows you the cumulative mortgage duty if you plan to refinance multiple times over your loan tenure, so you can see the total lifetime cost of refinancing.
The Owner-Occupied Property Tax Calculator takes your Annual Value and applies all progressive rate bands to compute the exact annual tax. It shows the breakdown by bracket so you can see exactly how each portion of your AV is taxed. It also shows the effective tax rate and the monthly equivalent, making it easy to budget.
The Non-Owner-Occupied Property Tax Calculator does the same computation but uses the higher landlord rate table. Crucially, it also shows you the side-by-side comparison — how much more you pay as a landlord versus if you occupied the property yourself. This “tax premium” is the hidden cost of being a landlord in Singapore that most rental yield calculations ignore.
3 Real Property Tax Examples for Singapore — HDB Owner, Condo Landlord and Landed Property in 2026
Example 1: 4-Room HDB Owner-Occupier in Tampines — AV S$16,800
Ah Kow and his wife live in their 4-room HDB flat which they bought for S$480,000. IRAS assigns an Annual Value of S$16,800 based on comparable rentals in Tampines.
At S$30 per month, property tax on an HDB flat is very affordable. But if Ah Kow rented out the flat instead, the tax would jump to S$2,016 (12% on S$16,800) — nearly 6 times more. Use the Owner-Occupied Calculator to check your flat type.
Example 2: Condo Landlord in Queenstown — AV S$42,000
Priya owns a 2-bedroom condo in Queenstown that she rents out at S$3,800 per month. IRAS assigns an AV of S$42,000.
The S$3,840 landlord premium reduces net rental yield by about 0.3% on a S$1.3 million condo. Many landlords forget to include this in their rental yield calculations. Use the Net Rental Yield Calculator to see the true return after all costs.
Example 3: Landed Property Owner in Bukit Timah — AV S$96,000
The Tan family lives in a semi-detached house in Bukit Timah. IRAS assigns an AV of S$96,000 based on comparable landed rentals in the area.
Landed property in prime districts carries heavy property tax because of the high AV. At S$13,280 per year (over S$1,100 per month), this is a significant holding cost. Use the Property Holding Cost Calculator to see your full monthly ownership burden including mortgage, property tax, maintenance, and insurance.
3 Expert Tips for Managing Mortgage Duty and Property Tax in Singapore
Factor Property Tax Into Your Rental Yield — Most Investors Forget
When computing net rental yield on an investment property, you must deduct the non-owner-occupied property tax rate, not the owner-occupied rate. On a condo with an AV of S$42,000, the difference is S$3,840 per year. On a S$1.3 million property, that alone reduces your yield by 0.3%. Add in maintenance fees, income tax on rental income, and vacancy periods, and many “profitable” rentals are barely breaking even. Use the Net Rental Yield Calculator alongside the Landlord Property Tax Calculator for accurate numbers.
Object to Your Annual Value If It Seems Too High
IRAS determines your AV using market rental data, but sometimes the assigned AV does not reflect reality — especially if your unit has unfavourable views, is on a low floor, or needs renovation. You have 30 days from the date of your property tax assessment notice to file an objection with IRAS. Provide evidence of actual rental transactions for comparable units (same block, similar floor, similar condition). A successful objection can reduce your AV and save you hundreds or thousands per year. Check your current AV on myTax Portal.
Refinancing Saves Money But Do Not Forget the S$500 Mortgage Duty
If you refinance every 3 years to chase lower SORA-linked rates, you save on interest but pay S$500 in mortgage duty plus legal fees (typically S$2,000-S$3,000) each time. Over 25 years, that is 8 rounds of refinancing costing S$20,000-S$28,000 in fees alone. Make sure the interest savings exceed the total switching cost. Use the Mortgage Refinancing Calculator to verify before switching.
16 Frequently Asked Questions About Mortgage Duty and Property Tax in Singapore
What is mortgage duty and how much does it cost?
Mortgage duty is a stamp duty of 0.4% charged on the mortgage loan amount, capped at S$500. For any loan above S$125,000 (which is virtually every Singapore property loan), you pay the maximum of S$500. It is a one-time payment per mortgage document, handled by your conveyancing lawyer.
Do I pay mortgage duty when I refinance my home loan?
Yes. Each new mortgage instrument requires fresh mortgage duty. If you refinance from Bank A to Bank B, you pay S$500 mortgage duty on the new mortgage. This is in addition to legal fees for the refinancing process. Factor this into your refinancing cost-benefit analysis.
What is Annual Value and how does IRAS determine it?
Annual Value is the estimated annual rent a property can reasonably command. IRAS determines AV based on actual rental transactions of comparable properties in the same area, adjusting for floor level, facing, and condition. AV is reviewed annually and forms the basis for computing property tax.
How is owner-occupied property tax calculated in Singapore?
Owner-occupied property tax uses progressive rates: 0% on the first S$8,000 of AV, 4% on the next S$8,000, 5% on the next S$2,000, 6% on the next S$37,000, and 10% to 32% on the remaining AV above S$55,000. The result is that HDB owners pay very little while luxury property owners pay significantly more.
How much more property tax do landlords pay compared to owner-occupiers?
Landlords pay substantially more. Non-owner-occupied rates start at 12% with no tax-free threshold, compared to 0% on the first S$8,000 for owner-occupiers. For an AV of S$30,000, an owner pays about S$1,320 while a landlord pays S$3,600 — nearly 3 times more.
Can I pay property tax in instalments?
Yes. IRAS offers GIRO instalment plans that let you pay property tax in monthly instalments instead of a lump sum in January. This is especially helpful for landed property owners where annual tax can exceed S$10,000. Apply through your bank GIRO or the IRAS myTax Portal.
What happens if I rent out one room of my HDB but live in the rest?
If you rent out one or more rooms while still living in the flat, your property is still classified as owner-occupied for property tax purposes. You enjoy the lower owner-occupied rates. However, the rental income is subject to income tax and must be declared to IRAS.
Is property tax different for HDB flats versus condos?
The tax rates are the same for all residential properties. The difference is in the Annual Value. HDB flats have lower AVs (typically S$10,000-S$25,000) compared to condos (S$24,000-S$60,000) and landed (S$48,000-S$150,000). Lower AV means lower tax because of the progressive rate structure.
When is property tax due each year?
Property tax is due on 31 January each year for the full calendar year. IRAS sends the assessment notice in December for the following year. If you are on GIRO, payments are deducted monthly from January to December.
Can I claim property tax as a deduction against rental income?
Yes. If you rent out your property, the property tax you pay is a deductible expense against your rental income for income tax purposes. Other deductible expenses include mortgage interest (not principal), maintenance fees, property agent commission, and fire insurance premiums.
How does property tax work for vacant properties?
If your property is vacant (not occupied by anyone and not rented out), it is classified as non-owner-occupied and taxed at the higher landlord rates. There is no special rate for vacant properties. This discourages owners from leaving units empty.
Does mortgage duty apply to HDB concessionary loans?
Yes. Mortgage duty applies to both HDB concessionary loans and bank loans. The S$500 cap means the duty is the same regardless of the loan type. Your HDB or bank lawyer handles the stamping as part of the conveyancing process.
What is the property tax for a S$1 million condo I live in?
It depends on the Annual Value, not the purchase price. A S$1 million condo typically has an AV of S$28,000 to S$38,000 depending on location and unit type. At an AV of S$33,000, the owner-occupied property tax is approximately S$1,560 per year (S$130 per month).
Can I object to my property Annual Value?
Yes. You can file an objection with IRAS within 30 days of receiving your property tax assessment notice. Provide comparable rental data to support your case. If successful, IRAS will revise your AV downward and adjust your tax accordingly.
Is there property tax on commercial and industrial property?
Yes. Commercial and industrial properties are taxed at a flat 10% of Annual Value with no progressive structure. There is no owner-occupied vs non-owner-occupied distinction for non-residential properties.
How does the property tax surcharge work for higher-value properties?
There is no separate surcharge. The progressive rate structure itself serves as the surcharge mechanism — higher AV properties pay a higher effective rate. For owner-occupied properties with AV above S$130,000, the marginal rate reaches 32%. This effectively targets luxury and high-value properties.
