Guidelines for Engineering Industry Taxpayers to Ensure Transparent Transactions and Investigation-Proof Accounting
1. Introduction:
The engineering industry forms a critical part of the industrial sector, encompassing heavy engineering enterprises like machine and equipment manufacturers, and light engineering enterprises producing consumer and industrial goods. Because of its size, diversity, and complex operations, this sector is highly vulnerable to tax disputes and investigations.
To avoid litigation and scrutiny, taxpayers must adopt transparent, compliant practices across procurement, production, sales, and accounting functions. These guidelines provide a checklist-based, descriptive framework for companies to manage transactions, internal controls, and statutory compliance, thereby minimizing the risk of adverse findings during tax assessments.
2. Organizational and Statutory Readiness
i. Clear Definition of Business Activities:
a) Maintain a documented business profile, including products, services, geographic reach, and technology used.
b) Regularly update records when expanding product lines or changing manufacturing processes.
c) Investigation Note: Clear business documentation prevents authorities from alleging undisclosed activities or hidden lines of production.
Statutory Registrations:
a) Ensure valid and updated registrations under GST, Companies Act, Factories Act, Labour Laws, and other applicable legislations.
b) File Annual Activity Certificates and other mandatory declarations with regulators like RBI, GST authorities, and Pollution Control Boards.
c) Investigation Note: Registration records are among the first documents examined by investigators. Delays or inaccuracies raise red flags.
Digital Record-keeping:
a) Adopt ERP or advanced accounting software like Tally for integrated, tamper-proof digital record maintenance.
b) Enable audit trails for every modification or deletion in digital records.
3. Procurement and Raw Material Management: Procurement is a sensitive area prone to manipulation through bogus purchases, inflated invoices, or unaccounted cash transactions.
Guidelines for Procurement:

ii. Reconcile contributions with salary registers.
(iv) Investigation Safeguard: Mismatches between muster rolls and statutory filings are treated as evidence of bogus wage claims.
6. GST and Indirect Tax Compliance: GST compliance is crucial, as discrepancies between GST returns and income-tax records often trigger investigations.
(i) Timely Filing of Returns:
i. File all required GST returns such as GSTR-1, GSTR-3B, GSTR-9, and GSTR-9C within due dates.
ii. Reconcile GST turnover with financial statements monthly.
(ii) Documentation under GST:
i. Maintain:
a) Records of outward and inward supplies.
b) Stock records for raw materials, finished goods, scrap, and wastage.
c) Separate accounts for advances received or paid.
d) Records of goods stored at multiple locations.
(iii) E-Way Bill Compliance:
i. Generate e-way bills for every movement of goods above threshold limits.
ii. Retain e-way bill logs for verification.
(iv) Investigation Safeguard: Failure to match GST records with production and sales data often leads to allegations of suppressed turnover.
7. Sales and Revenue Management: Sales records must be transparent and free from practices like under-invoicing or unrecorded cash sales.
(i) Invoice Control:
i. Pre-number all invoices and maintain a digital log to prevent tampering.
