What are the instruments chargeable to stamp duty?
Instrument includes every document by which any right or liability, is, or purported to be created, transferred, limited, extended, extinguished or recorded [section 2(17) of Indian Stamp Act]. Any instrument mentioned in Schedule I to Indian Stamp Act is chargeable to duty as prescribed in the schedule [section 3]. The list includes all usual instruments like affidavit, lease, memorandum and articles of company, bill of exchange, bond, mortgage, conveyance, receipt, debenture, share, insurance policy, partnership deed, proxy, shares etc. Thus, if an instrument is not listed in the schedule, no stamp duty is payable. ‘Instrument’ does not include ordinary letters. Similarly, an unsigned draft of an agreement is not an ‘instrument’.
