Stamp Duty and GST on Property in Karnataka: A Buyer's Guide

Two statutory charges apply to almost every property purchase in the state, and at ultra-luxury ticket sizes they stop being administrative details. Stamp duty and GST on property Karnataka buyers pay run at approximately 7.65% and 5% respectively — percentages that sound modest until applied to a figure above Rs 22 Cr.

Timing differs between the two, which matters for cash-flow planning. Stamp duty becomes payable at registration of the agreement, as a single event. GST at 5% applies to under-construction units and attaches to instalments as they fall due rather than arriving as one payment — so under a construction-linked payment plan, the GST component spreads across the build period alongside the principal instalments it accompanies.

Scale is the point most buyers underestimate. On a standard-format residence at roughly Rs 22 Cr – Rs 25 Cr, or a large format at roughly Rs 25 Cr – Rs 30 Cr, the combined statutory load is a substantial sum in absolute terms. Neither charge is negotiable, neither varies by developer, and neither improves with timing — including at financial year end, contrary to a persistent belief. Build both into your outflow model from the start rather than treating them as closing costs.

Several other charges sit outside the base price and outside these two, and conflating them causes budgeting errors. Preferred location charges apply to corner plots and the strongest privacy positions. Plot area above the 8,000 sft base attracts a per-sft premium. Club membership is a one-time charge at booking, and a maintenance corpus falls due at handover. Design customisation is quoted separately once design development begins, so it appears in no cost sheet issued at booking.

Two cautions before you rely on the figures above. Rates change with state policy and with central GST decisions, so verify the current position at the point you transact rather than assuming today's numbers hold. And this is general information rather than tax advice — how these charges interact with your own position, particularly if you are buying through an entity or from abroad, is a question for a qualified professional. Reviewing the the full charge structure will show how they sit within the full charge structure.
