What are the transitional provisions for contracts that were signed with the Government before the implementation of VAT?

Supplies listed in contracts signed with the Government before 1st of January, 2019, that would normally be taxed at the standard rate of VAT, are instead taxed at the zero rate. All government contracts will remain zero-rated until they are renewed or until the 31st of December 2023, whichever comes first. Any changes made to the contract will also be considered a renewal.
