The tax office reviews the annual value of homes every year for the purpose of calculating real estate tax.

Since the last round of annual value review, rents of HDB and private homes have increased by more than 20%.

However, all homeowners living in their own homes are entitled to a one-time 60% real estate tax rebate of up to $60.

So, if you deduct the one-time 60% rebate up to $60, most HDB owners will have to pay $30 to $70 more in real estate taxes next year.

One- and two-bedroom HDB flats will still have an annual value of less than $8,000 next year, so homeowners will not have to pay real estate taxes, but owner-occupiers of larger HDB flats will have to pay more taxes.

After deducting the rebate, they will have to pay $30 to $70 more than last year.

In the case of three-bedroom HDB flats, after deducting the rebate, homeowners will have to pay $20.80 to $40 in real estate taxes next year, $7.20 to $30.40 more than last year.

Four-room homeowners will have to pay $107.20 to $155.20, $33.60 to $45.60 more than last year.

Five-room homeowners will have to pay $40.80 to $52.80 more next year, reaching $148 to $196.

Apartment-style HDB homeowners will have to pay $176.80 and $224.80, which is $55.20 to $67.20 higher than last year.

Houses with higher annual values will also see higher real estate tax increases after rebates.
