Version-1 Dated:01.01.2021 


The GST is an integrated scheme of taxation of goods and services and is an efficient and harmonized consumption based tax system replacing a plethora of indirect taxes like VAT, Central Excise, Luxury Tax, Entry Tax, Entertainment Tax, Betting Tax and Cess and surcharges relating to supply of goods and services.

The Goods and Service Tax is a trust-based regime wherein the taxpayer is required to self-assess his tax liability and file the returns. To ensure whether the taxpayer has correctly self-assessed his tax liability, the concept of Audit has been incorporated under the GST Act. This involves examination of records, returns and other documents maintained by a registered taxable person.

The Audit involving scrutiny of financial statements and documents, therefore, forms an integral part of the work of the officers of the tax department. The objective of audit of taxpayers is to measure, improve and sustain the level of compliance in the light of the provisions of the KGST Act 2017 and the rules made there under.

Bringing out a manual on GST Audit is praise worthy initiative by the Commercial Taxes Department. The manual would be a comprehensive guide to conduct Audit under GST and would include the principles and policies of Audit under the Act. This hand book is an effort to equip the officers of the department with requisite skills in audit and scrutiny.

The purpose of this Audit manual is to outline the principles and policies of audit conducted under the KGST Act, 2017 and the rules made thereunder. Guidelines provided in the manual are intended to ensure that the audit of tax payers is carried out in a uniform, efficient and comprehensive manner adhering to the stipulated principles, policies and international practices. In addition there are also a few chapters towards the end which would be helpful to LGSTOs.

I do sincerely hope this effort of the Commercial Taxes Dep rtment is well received and the Officers and Officials of the Department benefit from it.

Government of Karnataka


It is gratifying to note that the KGST Audit Manual has been prepared by the Commercial Taxes Department in a comprehensive, holistic manner. I am sure it will serve as a guide to the officers implementing the provisions of the GST law.

The Commercial Taxes Department in association with NIC, Karnataka has also implemented an online audit backed system called E-Shodane. This is keeping in line with the various e-initiatives of the department over the years.

This Manual will be regularly updated based on feedbacks, amendments of rules and processes as well as experience of audit under GST.

The Manual is just an effort to synchronize the audit/ scrutiny process. It is not a legal document conferring rights and not a source of legal interpretation. The manual does not deal with legal interpretations and rulings on GST matters. Future changes in the KGST Act, 2017 and the rules made thereunder, administrative policies and procedures may require changes to this manual. This is work of collation from different sources and is for educational and training purposes only. This is for internal use by the officers of the Department only.
