GST Tax Compliance with Giddh

In 2024, India saw over 4.5 million GST returns filed incorrectly, with non-compliance penalties totaling over ₹18,000 crores. These statistics highlight a critical issue: while GST tax compliance is mandatory, many businesses, especially SMEs and mid-sized firms, continue to struggle with accurate filings.

If you are an Indian business owner or part of a finance team, you know how daunting GST compliance can be, given the ever-changing regulations and complex deadlines.

Many companies fail to remain compliant due to a combination of factors—misunderstanding tax codes, missing deadlines, or simply being overwhelmed by regulations.

This blog provides you with a clear GST tax compliance checklist to help you navigate the process without facing costly penalties.

Whether you're an accountant, business owner, or part of a finance team, we’ll walk you through essential steps to simplify your compliance process, reduce the risk of errors, and avoid penalties.

What Is Tax Compliance?

Tax compliance refers to a business's adherence to the relevant tax laws, which, in the case of GST, includes ensuring that all applicable taxes are paid and that accurate returns are filed on time. For GST, this means not just submitting returns but also maintaining accurate records of invoices, transactions, and tax credits.

Direct vs Indirect Tax Compliance

Tax compliance can be categorized as:

  • Direct Tax Compliance: Involves taxes like income tax, where businesses must ensure they file tax returns accurately based on profits.

  • Indirect Tax Compliance: GST falls into this category, where taxes are levied on goods and services. For GST compliance, businesses must ensure they meet all regulatory requirements, such as timely filing of returns and proper reconciliation of Input Tax Credit (ITC).

Why GST Compliance Is Critical for Indian Businesses

Indian businesses need to comply with GST regulations not only to avoid penalties but also to maintain good standing with tax authorities. Non-compliance can lead to fines, legal consequences, and even damage to a company’s reputation.

What GST Compliance Includes Under Indian Law

GST compliance means adhering to the rules of the Goods and Services Tax (GST) regime. This includes:

  • GST Registration: Registering with the GST portal if your business meets the threshold requirements.

  • Return Filing: Filing GST returns like GSTR-1, GSTR-3B, GSTR-9, and GSTR-9C.

  • Tax Payment: Paying the correct GST amount on time.

  • Record Keeping: Maintaining accurate records for GST-related transactions.

Who Must Comply with GST Regulations?

Any business whose turnover exceeds the threshold limit prescribed by the GST law must comply with the GST regulations. Even smaller businesses, particularly those with interstate transactions, may need to register and comply.

Consequences of GST Non-Compliance

Non-compliance can lead to:

  • Penalties: Late fees and fines for missed filings.

  • Interest Charges: For delayed payments.

  • Legal Action: If violations are severe.

Navigating GST compliance is essential for every Indian business, from small enterprises to large corporations. The Indian GST law mandates a series of procedures, filing requirements, and record-keeping standards that businesses must adhere to.

Non-compliance can lead to penalties, loss of input tax credit (ITC), and other legal issues. To stay on track and avoid costly business mistakes, here’s a comprehensive GST tax compliance checklist for Indian businesses.

GST Registration: Are You Registered?

Who Must Register?

  • Threshold Limit: Any business with an annual aggregate turnover above ₹20 lakh (₹10 lakh in special category states) must register for GST.

  • Optional Registration: Even if your turnover is below the prescribed limit, you can still choose to register for GST voluntarily. This allows small businesses to claim input tax credit (ITC) and enhances their credibility.

  • Multi-State Operations: If your business operates in multiple states, you need a separate GST registration for each state.

    Key Compliance Steps:

  • Ensure your GSTIN (Goods and Services Tax Identification Number) is valid and linked to the business.

  • Update your GST registration details whenever there are changes in your business structure or address.

Accurate Record-Keeping: The Backbone of Compliance

Maintaining accurate records is critical for ensuring GST compliance, particularly during audits.

What to Maintain:

  • Invoices: Keep detailed records of all sales and purchase invoices.

  • Receipts, Credit/Debit Notes: Maintain copies of all receipts and credit/debit notes issued and received.

  • GST Payments: Document all GST payments made, along with the GSTIN, HSN/SAC codes, and tax rates.

    Record Retention:

  • GST regulations require businesses to retain records for at least six years from the annual return filing date. This ensures that you have everything in place if the tax authorities conduct an audit.

    Automation for Accuracy:

  • Use small business accounting software to automate record-keeping, minimize errors, and ensure easy retrieval during audits.

GST-Compliant Invoicing

Invoices must meet specific GST requirements to be considered valid. Incorrect invoicing can lead to issues with input tax credit (ITC) claims and other compliance challenges.

GST-Invoicing Requirements:

  • GSTIN: Include the GSTIN of both the seller and the buyer.

  • Invoice Number and Date: Ensure that every invoice has a unique number and date.

  • HSN/SAC Codes: Accurately assign the correct HSN or SAC code to each product or service.

  • Tax Breakup: Show the total GST payable, divided by the applicable tax rate (CGST, SGST/UGST, or IGST).

  • Digital Signature: Include a digital signature, if required.

    E-Invoicing Requirement:

  • For businesses with a turnover above ₹10 crore, e-invoicing solution will be mandatory. This involves uploading invoices to the Invoice Registration Portal (IRP) for validation.

  • By April 1, 2025, invoices must be uploaded within 30 days of issuance, or businesses risk losing their input tax credit (ITC).

    Automation for Invoicing:

  • Use business accounting software to generate GST-compliant invoices and automatically upload e-invoices, ensuring you never miss a deadline.

Timely GST Return Filing

GST return filing is crucial for staying compliant and avoiding penalties. There are several returns businesses need to file, each with specific deadlines.

Key GST Returns:

  • GSTR-1 (Outward Supplies): Report all sales transactions. This return must be filed monthly or quarterly, depending on your turnover.

  • GSTR-3B (Summary Return): This summary return needs to be filed monthly, covering all sales and purchases, along with GST payments.

  • GSTR-9 (Annual Return): This return consolidates all your transactions for the financial year.

    Filing Frequency:

  • Use the QRMP (Quarterly Return Monthly Payment) scheme, if applicable, to reduce the frequency of filing.

  • Remember that late filings attract penalties and can result in blocked ITC.

    Automation for Filing:

  • Small business accounting software can automatically generate and populate GST returns from your transaction data, reducing manual errors and ensuring timely filings.

Input Tax Credit (ITC) Reconciliation

ITC allows businesses to offset the GST paid on purchases against their sales tax liabilities. However, incorrect ITC claims can lead to penalties and delays.

Reconciliation Steps:

  • Vendor Reconciliation: Match your purchase records with your suppliers’ GSTR-1 filings to claim eligible ITC.

  • Regular ITC Reconciliation: Reconcile ITC regularly to avoid mismatches. These mismatches can lead to ITC denial or delays in refunds.

  • Blocked Credit: Be aware that certain goods and services are ineligible for ITC, such as personal expenses and motor vehicles.

    ITC Eligibility:

  • As per recent changes, businesses can claim up to 99% ITC, provided they meet specific conditions.

    Automation for ITC Tracking:

  • Use GST compliance software to automate ITC reconciliation, track eligible credits, and alert you to any mismatches.

Reverse Charge Mechanism (RCM) Compliance

Under the Reverse Charge Mechanism (RCM), the recipient of goods or services must pay GST instead of the supplier. This is applicable to certain categories like the import of services or transactions with unregistered dealers.

RCM Compliance:

  • Identify all transactions subject to RCM, such as:

    • Purchases from unregistered suppliers.

    • Import of services.

    • Payments like legal fees or consultancy fees.

  • Ensure that you pay GST under RCM and file the relevant returns on time.

    Automation for RCM Transactions:

  • GST compliance software can help identify RCM transactions and generate reports automatically, ensuring accurate and timely filings.

E-Way Bill Generation

An E-Way Bill is required for the transportation of goods that exceed a specified value. Without the E-Way Bill, goods cannot be moved between locations.

E-Way Bill Requirements:

  • Generate E-Way Bills for all consignments exceeding ₹50,000.

  • Ensure that all details (such as vehicle number, sender, receiver, and goods details) are accurately filled.

  • Any discrepancies may cause delays in shipments or penalties.

    Stricter Rules from 2025:

  • In 2025, the E-Way Bill process will become stricter, with two-factor authentication required for transactions.

    Automation for E-Way Bill Generation:

  • Small business accounting software can simplify E-Way Bill generation by automatically filling in the required details, reducing manual entry and errors.

GST Composition Scheme: Are You Eligible?

The GST Composition Scheme allows small businesses with a turnover of up to ₹1.5 crore (₹75 lakh for service providers) to pay taxes at a lower rate and enjoy simpler compliance.

Eligibility Criteria:

  • Your business must have a turnover below ₹1.5 crore.

  • The scheme is not available for businesses making inter-state sales or those who want to claim ITC.

    Considerations for the Scheme:

  • The Composition Scheme offers lower tax rates but disallows ITC claims.

  • If your business grows beyond the threshold limit, you must switch to the regular GST scheme.

    Automation for Scheme Eligibility:

  • Accounting software can help track your turnover and automatically assess whether you're eligible for the GST Composition Scheme.

Stay Updated with GST Amendments

GST rules and regulations undergo frequent changes. To stay compliant, businesses must stay current with amendments, especially those in 2025.

Anticipated Changes in 2025:

  • Compulsory multi-factor authentication (MFA) for accessing the GST portal.

  • Stricter penalties for non-compliance and new invoice series requirements.

  • Regular updates to the E-way Bill system.

    Automation for Compliance Updates:

  • Many small business accounting solutions automatically update the software to reflect new GST rules, ensuring your business stays compliant without manual intervention.

Year-End GST Compliance Checklist

At the end of the financial year, businesses must ensure that they are fully compliant and ready for audits.

Year-End Compliance Steps:

  • Ensure all GST returns are filed, and payments are made.

  • Reconcile ITC and finalize all accounts.

  • Renew Letter of Undertaking (LUT) for exports, if applicable.

  • Maintain an audit trail and preserve all records for at least five years.

    Automation for Year-End Compliance:

  • Accounting software offers year-end checklists, easy access to historical records, and audit-ready reports, making year-end compliance smoother and more efficient.
