Stamp duty and registration in Karnataka, 2026 edition
The current slabs, how the BBMP urban cess works, and how it's calculated on under-construction units.
By Ankit Rao2 April 20265 min

Slabs (2026)
- Above ₹45 lakh: 5% stamp duty
- ₹21 - ₹45 lakh: 3% stamp duty
- Below ₹21 lakh: 2% stamp duty
- Registration: 1% across all slabs
- BBMP urban cess (within BBMP limits): typically 0.5-0.65% additional
On under-construction units
Stamp duty is computed on the higher of (a) sale-deed value or (b) state guidance value for that locality. Verify the guidance value with the sub-registrar office; it is updated periodically.
Joint ownership
There is no separate concessional rate for women-only buyers in Karnataka (unlike Maharashtra). Joint ownership with a spouse or major child can help on the loan-eligibility side, but does not reduce stamp duty.
Practical math
For a ₹1.5 Cr Bangalore apartment within BBMP limits:
- Stamp duty (5%): ₹7,50,000
- Registration (1%): ₹1,50,000
- BBMP cess (0.5%): ₹75,000
- Total: ₹9,75,000
