We are manufacturer of Welding Machinery. We received an order from COS, Western Railway, Mumbai in May 2017. The rate of CST chargeable was 6.05%. The material against this order is going to be supplied in July 2017. Now with the implementation of GST, the rate of tax is 18%.
Is there any provision in the GST Act regarding this matter, wherein the purchaser, that is, The Western Railway, has to automatically change the rate of tax in its order?
Please provide information. Thank you.
GST transition and contract tax clause determine which tax rate applies to supplies delivered after tax reform implementation. Whether the tax rate for supplies ordered before GST implementation but delivered afterwards is governed by the contract depends on the contract's tax clause-whether taxes were fixed, tied to the rate at time of supply, or allocate change-in-law risk-and, absent an express provision, parties should seek an amended order or revised agreement to reflect the applicable tax regime at time of supply.
