Let's say I bought a property under development. So I sign S&P with the developer and pay the stamp duty based on the sales price of say 500k. Ok no issue.

3 years later take possesion of the property and live in it.

Strata title comes out in another 3 years. By this time, lets say that property price has gone up to 800k.

The developer say I have to pay another round of stamp duty before the title can be transfered to me, but this time the calculation will be based on 800k valuation.

So is this true that we have to pay stamp duty to the HASIL twice on every property transaction?
