Fun facts, the real cost of your IWK is the 1% KWSMP (contribution cost) developers paid during the construction of your pripertoes.

Said your properties are worth 1M, you already paid RM10k of contribution cost for it.

Did that with one of their indahportal few months back. Uploading support document like your cukai taksiran to proof you’re the new owner.

Surprisingly their reply is pretty prompt (in just a day or so IIRC).

Now the new bill keluar, indeed on my name.

Pro-rating of the bills came under your purchasing agreement with your seller/buyer. The expected norm is old owner/seller clearing whatever pending bills up to the month he’s passing you the key (like IWK/Taksiran this type of half yearly/yearly bill, they pay the full amount required by the date). Then they’ll bill the buyer the pro-rated/ratio balance of the bill after the transaction completing date (say your transaction completed in March, seller borne the bill Jan to March, while asking the balance from buyer from March onwards).
