Estimate your annual property tax from the Annual Value (AV) using current progressive rates. The AV is the estimated yearly rent your property could fetch.
Property tax is an annual tax on property ownership, calculated as Annual Value × progressive rate. The AV is IRAS's estimate of the yearly market rent your property could fetch unfurnished — it is not your actual rent or your mortgage.
Owner-occupier rates (from 1 Jan 2025) run 0% on the first S$12,000 of AV up to 32% above S$140,000, so most owner-occupied HDB flats and many condos pay little. Non-owner-occupier (rented, vacant or company-owned) residential rates are higher, from 12% on the first S$30,000 up to 36% above S$60,000. Only one home you live in qualifies for owner-occupier rates; additional homes are taxed at the higher rates even if you occupy them.
