A demat account also helps avoid problems typically associated with physical share certificates, for example: delivery failures caused by signature mismatch, postal delays and loss of certificate during transit. Further, it eliminates the risks associated with forgery and due to damaged stock certificates. Demat account holders also avoid stamp duty (as against 0.5 per cent payable on physical shares) and filling up of transfer deeds. Demat account holders usually obtain quicker receipts of benefits like stock splits and bonuses.
The other advantage is the ability to access stocks, bonds, ETFs, IPO, Gold ETF, etc. all in one place. Its like one centralized investment account from where you can access and maintain investment products.
