The effective date is usually either the date of conclusion of the contract or the substantial performance of a contract or leasing contract, if this is the case previously. Transactions whose effective date was before March 1, 2019 are subject to a 30-day deadline. Where a lease is essentially complied with, paragraph 12A refers to a fictitious lease as having a substantial performance for a period beginning on that day and ending at the end of the term of the lease itself. A lease is often preceded by a lease. While this may legally function as a fair lease agreement, SDLT is treated as a contract that can be charged to SDLT in certain circumstances: – the SDLT is payable on the “effective date” of the lease agreement. . . .
