Interest on delay payment of tax on RCM

A user is asking about potential relief for interest charged on delayed payment of GST under the Reverse Charge Mechanism (RCM) for transportation charges incurred in 2018-19. The department has raised an issue during an audit, demanding payment of GST with interest, while allowing input tax credit (ITC) after payment. The user believes their client should be eligible for ITC, as there's no revenue loss to the government. Experts suggest there is generally no specific relief for such interest charges, as interest compensates for the time value of money due to late payment.
