4. Major Improvements in GST Over Time

The GST system has undergone several refinements to enhance compliance, ease of doing business, and tax collection efficiency. Here are some key improvements:

A. Introduction of E-Invoicing

E-invoicing was made mandatory for businesses with turnover above ₹500 crore in 2020, gradually extending to smaller businesses. This ensures real-time reporting and reduces tax evasion.

B. Simplification of GST Returns

The earlier return system (GSTR-1, GSTR-2, GSTR-3) was replaced with a simplified return filing system, reducing compliance burdens on taxpayers.

C. GST Rate Rationalization

GST rates have been revised multiple times to make taxation more industry-friendly. Luxury and non-essential items have higher tax rates, while essential commodities are taxed lower.

D. Auto-populated GSTR-2A/2B

Auto-generated purchase returns (GSTR-2A & GSTR-2B) help businesses reconcile their input tax credit with suppliers’ filings, minimizing discrepancies.

E. Compliance Relaxations for Small Businesses

• Increase in the Composition Scheme threshold from ₹1 crore to ₹1.5 crore.

F. Reduction in Late Fees and Penalties

Late fees for return filing have been reduced, benefiting small and medium businesses facing financial challenges.
