Goods and Services Tax (GST) compliance has become increasingly data-driven, and tax authorities now rely heavily on return analytics and reconciliations to identify discrepancies. As a result, GST audit preparation is no longer optional, it is essential for every registered business. Poor preparation can lead to notices, penalties, blocked input tax credit, or even departmental scrutiny.
With the modern accounting applications such as Tally Prime, businesses can keep their books in order, automate on reconciliation and be audit ready all through the financial year with minimal stress.
What is GST Audit and Why Preparation Matters
GST audit is a professional review of the records, returns and financial statements of a taxpayer with a view to ascertaining whether taxes have been duly reported and paid in accordance with the GST law.
The audit process focuses on:
- Accuracy of GST returns filed
- Proper maintenance of the books of accounts
- Correct input tax credit (ITC) claims
- Goods and services classification
- Tax payment compliance
Notice can be caused by even minor differences between books and returns. So, advanced preparation can help to avoid compliance risks to a greater extent.
GST Audit Applicability: Who Needs to Prepare
Understanding GST Audit Applicability is important for businesses.
Under the GST law, audits may occur in different forms:
Departmental Audit (Section 65)
Conducted by GST officers at the taxpayer’s premises or office.
Special Audit Under GST (Section 66)
Ordered by tax authorities when complexity or discrepancies are suspected. It is conducted by a Chartered Accountant or Cost Accountant nominated by the department.
Internal GST Audit
Businesses voluntarily conduct internal audits to ensure compliance and avoid penalties.
Regardless of applicability thresholds, proactive preparation is always recommended.
Role of GST Returns in GST Audit Preparation
GST returns are the primary documents auditors review.
Key returns include:
- GSTR-1 -Outward supplies information.
- GSTR-3B -Summary return and payment of tax.
- GSTR-2B – Auto generated ITC statement
Auditors compare these returns with the books of accounts to identify inconsistencies.
