1) In case of on-going projects where construction has been started and booking is done before 31.03.2019, there is an one time option available to the developer and builders to charge GST @ 12% with ITC i.e. you will be charged GST @9% which is current rate. Second option is charging GST @5% without ITC on all payments on or after 01.04.2019. Builder has to follow one option uniformly. he can not adopt different options with his customers. In case of GST@5% without ITC, cost will be increased. In agreement there might be a clause of escalation in prices.
2) The new rates are proposed keeping in view the complaints received by the anti-profiteering authority and various other reasons, one if which is to provide benefit to consumers by reducing the rate. In scenario, cost of the builder is bound to increase.
3) Same as above.
4) You have to check with the builder what option he is exercising. It is better if pool of consumers do the comparative calculations before and after introduction of new GST rates.
Thanks
