Frequently Asked Questions

What is the standard GST rule on housing society maintenance in India?

As per CBIC circulars, if an RWA or Co-operative Housing Society has an annual turnover exceeding ₹20 Lakhs and charges more than ₹7,500 per month per member in maintenance, GST at 18% is leviable on the entire maintenance amount. If charges are ₹7,500 or less per month per member, they are completely exempt from GST.

What is the difference between per sq.ft. and fixed maintenance models?

In a per-square-foot model, larger flats pay proportionally higher maintenance to reflect their higher undivided share of land (UDS). In a fixed model, every apartment pays an identical amount irrespective of area, reflecting equal access to common amenities like elevators, security guards, and clubhouses.

What is a Sinking Fund and how is it calculated in housing societies?

A Sinking Fund is a statutory reserve created for future major repairs, structural strengthening, or building reconstruction. Under state Co-operative Housing Society bye-laws (e.g., Maharashtra), it is typically calculated at 0.25% of the construction cost of the flat per annum, or as a set percentage of the monthly maintenance bill.
