Blockchain-Based GST Filing Support System for Small-Scale Industries

Abstract

Small-scale enterprises struggle to comply with the Goods and Services Tax (GST) filing process due to limitations in traditional centralized systems. Traditional platforms rely heavily on intermediaries, incur high compliance costs, have sluggish approval times, lack real-time validation, and are prone to manipulation and fraud. The study solves these inefficiencies through the implementation of a blockchain-based GST filing support system based on decentralization, smart contracts, and immutable distributed ledgers. It eliminates human processes and third-party validation services while maintaining a tamper-proof record of GST transactions through automated validation and safe storage. It empirically demonstrates that the proposed system outperforms by increasing efficiency by up to 83.1%, lowering filing error rates to 2.3%, reducing duplications to 1.1%, and providing 88.7% fraud detection accuracy. The result represents a revolutionary strategy for all small-scale industries, improving not only processing time, scalability, and transparency, but also the trust of all stakeholders involved.
