@Aman, Stamp duty is collected on the basis of property value at the time of registration. SD’s amount varies from state to state and also property type – old or new. Since it adds up to the property cost, it’s better to have a fair idea before finalize your property deal.
Stamp Duty is payable under Section 3 of the Indian Stamp Act, 1899. Rates of stamp duty payable for different types of documents are as per Schedule I. Stamp Duty must be paid in full and on time. If there is a delay in payment of stamp duty, it attracts penalty. A stamp duty paid document gets penitentiary value and is admitted as evidence in Court. Document not properly stamped, is not admitted as evidence by the Court.
