Global VAT/GST Compliance & Margin Audit Guide

Value Added Tax (VAT) is an consumption tax assessed on the value added to goods and services at each stage of production. When calculating VAT, transactions are classified as either tax-exclusive or tax-inclusive:
  • Tax-Exclusive: The tax is added to the base cost. VAT = Base × (Rate / 100).
  • Tax-Inclusive: The listed gross price already contains the tax component. The base value must be extracted using the formula: Base = Gross / (1 + (Rate / 100)). The tax component is the difference: VAT = Gross - Base.

The Reverse Charge Mechanism (RCM) is an international tax rule designed to simplify cross-border B2B supply of services and goods. Instead of requiring the foreign supplier to register for VAT in the buyer's country, the responsibility to report and pay tax shifts to the customer. The seller records 0% Output VAT on their invoice, and the buyer self-assesses both the Output VAT and the corresponding Input VAT on their local tax return, typically resulting in a neutral cash flow impact.

Input Tax Credit (ITC) is the core mechanism that prevents VAT double taxation. When a business purchases raw materials, software, or services to run operations, it pays VAT to its suppliers (Input VAT). When the business sells its final products, it collects VAT from customers (Output VAT). The business only remits the net tax payable: Net VAT Payable = Output VAT - Input VAT. If Input VAT exceeds Output VAT (due to heavy capital investments or low sales), the surplus constitutes a Refundable Tax Credit Asset, which can be claimed back from the government.
