How to Activate Cancelled GST Registration: Steps for 30 Days to 3 Years Period


GST is an integrated tax system, which replaces several indirect taxes imposed by both the central and state governments. This is expected to reduce the cost of goods and services, boost the economy and make our products and services globally competitive. GST laws are regularly amended to simplify the GST regime and make the regulation fair for all. However, at the same time the government is also focusing on making the GST taxation laws more stringent than before. Often, situations arise when GST is cancelled for many businesses. There are various reasons for this. Sometimes, businesses cancel it on their own, and other times, the GST department cancels it.

  • Even after cancellation, any business is required to file GST returns and pay all outstanding taxes. If he fails in any way to comply with these requirements or fails to maintain records for the specified period, he may also be punished as a consequence.
  • If your registration has been cancelled by officer and yet you are collecting GST, then in such a situation you may have to pay a penalty and this can also significantly increase your financial burden.
  • After registration is cancelled, a business basically cannot claim input tax credit on purchases, which means the cost of your goods may increase because in case of cancellation the business cannot recover the GST paid on inputs.
  • If your registration is cancelled then it also raises questions about the reputation of your business. Basically, it affects the reputation of your business more when the matter is of fraud or deception, i.e. your registration has been cancelled due to fraud or deception.
