“The key issue which is now creating problem is the matching of the credit. The fear among the business community is that in earlier regime there was only one return and matching of the credit was a problem then. Now with three monthly returns it is likely to increase further. There are several rates in this new regime. For example, a hotel goes into multiple rates which will have several different slabs in the restaurant and rooms,” said Mr Sandip Bhandare, noted Chartered Accountant in Goa.
