Regulatory Framework: Section 31 Invoicing Rules
Under the statutory regulations enforced by the Central Board of Indirect Taxes and Customs (CBIC), compiling accurate invoice metrics is a hard legal mandate for registered tax entities across India. Section 31 of the CGST Act defines the specific rules governing structural layout criteria for valid business-to-business (B2B) document generation paths.
The Core Tax Splits Demystified
The allocation tracking matrix for Goods and Services Tax relies completely on the geographical transaction category:
Intra-State Supply Channels: If the supplier and recipient entities are located inside identical state boundaries, the transaction triggers localized accounting protocols. The asset rate is split down the center into **Central GST (CGST)** and **State GST (SGST)** components, apportioning revenue pools equally to federal and regional jurisdictions.
Inter-State Supply Channels: If the transaction breaks across regional borders, localized splitting models are bypassed entirely. The entire consolidated balance scales within the single **Integrated GST (IGST)** tracking layer, routing total collections to central clearing pipelines before subsequent federal apportionment runs.
