If you own a home in Singapore, you will see the phrase “annual value” on your property tax bill, and increasingly it decides more than just that bill. The annual value of your property is a figure set by the Inland Revenue Authority of Singapore (IRAS), and it quietly influences how much property tax you pay and whether you qualify for certain government support schemes. Yet many owners have no idea where the number comes from or what to do if it looks wrong.
This guide explains, in plain terms, what annual value is, how it is worked out, and why it matters. It is general information, not tax advice, and it deliberately avoids quoting current rates or thresholds, because these are reviewed regularly. For anything that affects your tax or eligibility, check the current position with IRAS.
What Annual Value Actually Means
The annual value (AV) of a property is, in simple terms, the estimated yearly rent the property could fetch if it were rented out, excluding furniture, furnishings and maintenance fees. It is a notional figure. It does not matter whether you actually rent the home, live in it yourself, or leave it empty; IRAS still assigns an AV based on what the property could reasonably rent for.
Two points often trip people up:
- It is not the price you paid. Annual value is about rental potential, not the purchase price or the current market value of the home. A property can be worth a great deal to buy yet carry a much smaller annual value.
- It is not your actual rent. Even if you rent your place out, the AV is IRAS’s own estimate of market rent, not necessarily the exact rent in your tenancy agreement.
Because AV tracks the rental market, it can move up or down over time as rents in the area change. IRAS reviews annual values and may revise them, which is why your property tax can shift from year to year even if you have done nothing to the home.
How IRAS Works Out the Annual Value
IRAS determines annual value by looking at the rents that comparable properties in the area are actually fetching. In broad strokes, the process considers factors such as:
- The market rents of similar nearby properties, in the same or comparable developments.
- The size, type and layout of your property, for example a three-room flat versus a five-room flat, or a condominium unit versus a landed home.
- The location and the general condition of the property.
For a property that is genuinely rented out, the actual rent gives IRAS a strong reference point, but the AV is still based on prevailing market rents rather than simply copying your lease. For owner-occupied and vacant homes, IRAS estimates what the property would rent for by comparison with similar let properties. Because the assessment leans on rental evidence, factors that raise rents in your neighbourhood, such as a new MRT station or improved amenities, can eventually feed through into a higher AV. Our guides on what affects a property’s value and buying property near an MRT line explore those same forces from the buyer’s side.
You do not calculate your own AV. IRAS sets it and notifies you, and it appears on your property tax notice.
Why Annual Value Matters to You
Annual value is not just a bureaucratic label. It has real effects on your wallet and your access to certain schemes.
Property tax. This is the main one. Your property tax is worked out by applying a tax rate to your annual value. Singapore uses different rate structures for owner-occupied homes and for homes that are not owner-occupied, such as those rented out or left vacant, with owner-occupiers generally taxed more lightly. The rates are tiered, so a higher AV can push part of your property into a higher band. Because both the AV and the tax rates can be revised, your annual bill is not fixed. This is a recurring cost of ownership, and it belongs in your planning alongside the others we set out in the costs of owning a home.
Eligibility for government schemes. Over the years, the Government has increasingly used annual value as one way to means-test support, since it is a rough proxy for the type of home someone lives in. Various rebates, subsidies and support measures have referenced AV bands to decide who qualifies. This means your home’s AV can affect more than tax, and it is another reason to know your number.
The table below sums up how the same property can be treated differently. The entries are general illustrations only, not current rates or thresholds.
| Factor | Owner-occupied home | Non-owner-occupied home |
|---|---|---|
| Who lives there | You and your household | Tenants, or left vacant |
| Property tax treatment | Lower, concessionary rate structure | Higher rate structure |
| Basis of the tax | Same annual value figure | Same annual value figure |
| Effect of a higher AV | Larger bill, may cross a band | Larger bill, may cross a band |
| Scheme eligibility | May be assessed against AV bands | Usually not relevant if not your home |
To get the concessionary owner-occupier treatment, you generally need to apply to IRAS and actually live in the property. Do not assume it applies automatically.
What to Do If Your Annual Value Looks Wrong
Because AV drives real costs, it is worth a look when your tax notice arrives. If you believe your annual value is too high, perhaps because rents in your area have softened, or the assessment does not reflect your property, you have the right to object to IRAS within the stated window. An objection needs to be reasoned, ideally supported by evidence such as recent rents of comparable units, rather than simply a wish to pay less.
A few practical habits:
- Check the notice each year. Note whether your AV has been revised and by how much.
- Keep rental evidence. If you rent the home out, keep your tenancy agreements. If you are objecting, gather rents of genuinely comparable nearby units.
- Mind the deadline. Objections must be filed within the period IRAS specifies. Do not sit on it.
- Update your status. If you move in, move out, or rent the place out, tell IRAS, because it changes which tax treatment applies.
For anything involving numbers, appeals or your specific tax position, deal with IRAS directly or engage a tax adviser.

Annual values, property tax rates, tax bands and scheme thresholds are set by the authorities and change over time, so always verify the current figures and rules with IRAS before you rely on them.
