Stamp duty is where the State you operate in changes the calculus, because the Indian Stamp Act 1899 leaves the rate to State legislation. In Maharashtra, an MoU that records an agreement and is executed in the State attracts duty under the Maharashtra Stamp Act 1958, and Mumbai deals are routinely stamped to keep the instrument admissible before the Bombay High Court. Practitioners there are especially careful with property-flavoured MoUs, which the registration authorities scrutinise closely.
In Karnataka, the Karnataka Stamp Act 1957 governs, and Bengaluru's dense startup and IT-services ecosystem produces a high volume of MoUs and term sheets. The recurring local issue is the term sheet that blends binding confidentiality with non-binding valuation heads, and Karnataka practitioners draft the carve-out tightly to avoid a premature-contract argument.
In Delhi, MoUs are stamped under the Indian Stamp Act 1899 as applied to the National Capital Territory, and the volume of government and institutional cooperation MoUs is unusually high. Here the drafting convention leans towards expressly non-binding language, because public bodies rarely want a cooperation record read as a funding commitment.
In Tamil Nadu, the Tamil Nadu stamp regime applies and Chennai's manufacturing and automotive supply chains generate vendor MoUs that frame long supply relationships. The local caution is to keep the MoU from accidentally fixing price and quantity in a way that converts it into an enforceable supply contract before the parties intend. Across every State, the safe rule is to stamp on execution and never assume a uniform national rate. Many of these MoUs feed directly into a shareholders agreement or partnership deed under the Companies Act 2013 once the deal closes.
