Who Pays GST: Builder or Buyer?
The buyer pays GST to the builder, which is included in the property agreement. The builder then remits this amount to the government. This applies only to new properties sold before completion.
No GST on Ready-to-Move Flats
If the builder completes the construction and obtains a Completion Certificate before the sale, the unit is considered ready-to-move-in, and no GST is charged. This makes ready properties more attractive to buyers looking to save on taxes.
GST for Builders on Raw Materials & Services
| Input | GST Rate |
|---|---|

| Paints and hardware | 18% |

Conclusion
The gst on builder and developer also applies to joint development models, where the builder shares revenue or property units with landowners. Knowing the GST regime for builders is essential for both property buyers and developers. While GST has streamlined taxation in real estate, it still adds a significant cost—unless you’re buying a ready-to-move property. Always check project status and GST applicability before signing the dotted line.
