The government may not accept the industry’s demand to substantially reduce Goods and Services Taxes (GST) for six months to boost demand as the exemption would block input-tax credit that would have an adverse impact on businesses and may not result into any significant gain to the consumer, two finance ministry officials said.The GST exemption will make output tax as zero and thus the input-tax credit would be blocked, which will be added to the cost making the product costlier, the officials with direct knowledge of the matter said requesting anonymity.“This will not only be injurious to the industry but also to the consumer at large and this is certainly not going to revive the demand,” one of the officials said.
