Dear Members,

I booked and registered a flat in Pune during March 2026 and paid GST. I recently found out that a Partial OC covering the entire building (including my flat) was issued earlier, in November 2025.

​Since GST is not applicable post-OC, it was collected in error. The builder has already deposited the amount with the government and is refusing to assist with a refund.

​How can I claim a GST refund in this case? Please advise.
