How Stamp Duty Works for Farmland in Karnataka
When you buy agricultural land in Karnataka, you pay stamp duty to the state government and a registration fee to have the sale deed officially recorded. Together, these add approximately 6.5% to the transaction cost. Understanding both is essential before you negotiate a price.
What Is Guidance Value?
Guidance value (circle rate) is the minimum property value the government recognises for stamp duty purposes. Even if you agree to pay less privately, duty is levied on the guidance value. For agricultural land in the Thalli/Hosur corridor and Kanakapura, guidance values are typically much lower than the actual market price — meaning your stamp duty cost is lower than you might expect.
You can look up the guidance value for any survey number in Karnataka at kaveri.karnataka.gov.in → Online Guidance Value. You'll need the district, taluk, hobli, and village name.
Karnataka vs. Tamil Nadu: Why It Matters
One Acre Farms projects span both states. Karnataka charges ~6.5% total (stamp + registration), while Tamil Nadu charges 11%. For a ₹30L plot, that's roughly ₹1.95L in Karnataka versus ₹3.3L in Tamil Nadu — a difference of ₹1.35 lakh on the same purchase price.
However, guidance values in the Tamil Nadu Hosur/Thalli corridor are typically low — so the absolute stamp duty amount may still be comparable to Karnataka even at a higher rate.

NRI Buyers — Additional Steps
Karnataka repealed Sections 79A and 79B in 2020 — any Indian citizen can now buy agricultural land here without being an agriculturalist. Tamil Nadu has no such restriction either. However, NRI buyers must route funds through NRE or NRO accounts per FEMA guidelines. The stamp duty and registration process is identical; only the source of funds differs.
