Stamp duty on the higher of two numbers

Stamp duty is charged on whichever is higher, the price you agreed or the circle rate value — so a good negotiation does not lower the duty, it only widens the gap between what you budgeted and what the sub-registrar asks for on the day. And the circle rate is quoted per unit of area, so the figure to compare is the rate times the area, not the rate. This works out both numbers, says which one wins, prints the difference as money, and applies the woman-buyer concession where it actually applies: to the duty rate, not to the registration charge.

Indian property buyers, agents and small conveyancing practices working out what is due at registration.

How it works

  1. Enter the agreement value, the area, and the circle rate per unit of area.
  2. Enter the duty rate for your state, the registration rate, and a cap if your state has one.
  3. Say whether the woman-buyer concession applies and how many points it takes off the duty rate.
  4. Read the total, and the difference between it and what budgeting on the agreed price would have given.

What you gain
