Interest on delayed tax payment applies to taxpayers who fail to remit GST, accruing from day after the due date. Every person liable to pay tax who fails to remit tax within the prescribed period must pay interest for the period the tax remains unpaid at a rate notified by the Government on the recommendations of the Council, calculated in the prescribed manner from the day succeeding the date the tax was due. A taxable person who makes an undue or excess claim of input tax credit or an undue or excess reduction in output tax liability must pay interest on the undue or excess amount at a rate notified by the Government on the Council's recommendations, subject to the specified upper limit.
