What is a GST Audit?
A GST audit involves the examination of a registered taxpayer’s financial records to verify the
accuracy of reported turnover, tax payments, input tax credit (ITC) claims, and refund applications
under GST laws.
The GST audit is a critical compliance measure to ensure transparency in tax reporting, whether
conducted by the tax authorities or a Chartered/Cost Accountant appointed by the taxpayer.
Why are GST Audit Services Important?
• Legal Compliance: Tax audits exist under GST laws to satisfy specific compliance requirements.
Failure to meet legal requirements for audits will result in both fees and various legal repercussions.
• Error Identification: Audits enable organizations to detect inconsistencies in their tax reporting
and financial documentation allowing them to resolve problems in advance.
• Avoid Penalties: Inaccurate GST return filing and improper Input Tax Credit (ITC) claims can result
in penalties and interest. GST audits help organizations mitigate these potential risks.
• Internal Control: Audits help organizations detect their internal process weak points and
strengthen financial systems combined with better GST compliance practices.
