We are about a week since the historic implementation of the Goods and Services Tax (GST), with many heralding it as the good simple tax. From the initial idea of what the GST was supposed to do, the current version is still not as simple as one would want it to be. For instance, the earlier one tax is actually now spread over four tax rate slabs. Likewise, there is an integrated GST (IGST), which one will need to pay when goods are passing across states, and there is provision to claim tax credit on IGST, which is well documented and explained.
