The correct answer is: C. 15th of the succeeding month.
The details of outward supplies of goods or services shall be submitted by the 15th of the succeeding month. This is according to the provisions of the Goods and Services Tax (GST) Act, 2017. The Act requires all registered taxpayers to file a monthly return, which includes details of all outward supplies made during the month. The return must be filed electronically through the GST portal.
The due date for filing the monthly return is the 15th of the succeeding month. However, taxpayers can avail of an extension of up to 15 days by paying a late fee. The late fee is 100 rupees per day, up to a maximum of 5000 rupees.
Taxpayers who fail to file the monthly return by the due date will be liable for a penalty of 500 rupees. The penalty will be increased to 1000 rupees if the return is filed after the extended due date.
In addition to the penalty, taxpayers who fail to file the monthly return will also be liable for interest on the tax due. The interest rate is 18% per annum.
It is important for taxpayers to file the monthly return on time to avoid any penalties or interest. The return can be filed easily through the GST portal.
