GST vs VAT
India’s unified indirect tax versus the pre-2017 state-level Value Added Tax — cascading, coverage, and federal design.
Start here
Goods and Services Tax (GST) is India’s unified destination-based indirect tax on goods and services with nationwide Input Tax Credit; Value Added Tax (VAT) is the erstwhile pre-2017 state-level goods tax with limited inter-state credit.
Before July 2017, a shirt manufacturer in Ludhiana paid excise to the Centre, VAT to Punjab, and faced entry tax at state borders. GST replaced this patchwork with one chain of credit from raw material to retail — for both goods and services.
Examiners love asking what GST fixed (cascading, tax-on-tax) and what constitutional change made it possible (101st Amendment, GST Council).
Side-by-side comparison
| Feature | GST | VAT |
|---|---|---|
| Implemented | July 1, 2017 (101st Constitutional Amendment) | State VAT from 2005 (replacing sales tax) |
| Rate setting | GST Council (Centre 1/3 vote, States 2/3) | Individual state governments for VAT |
| Threshold | ₹40 lakh (goods, most states); ₹20 lakh (services) | Varied by state (typically ₹5–10 lakh) |
| E-way bill | Mandatory for inter-state movement above threshold | Limited or no unified national system |
| Taxes subsumed | Central excise, service tax, VAT, CST, entry tax, octroi (most) | Replaced state sales tax; Central excise continued separately |
| Registration | Single GSTIN per state of operation | Separate VAT, excise, and service tax registrations |
At a glance
Coverage
Goods and services
Goods only (services taxed separately — Service Tax)
Cascading
Minimized via nationwide ITC
Partial; Central–State taxes did not fully offset
Structure
Dual GST (CGST/SGST/IGST) + GST Council
State VAT + separate Central excise/service tax
Inter-state trade
IGST + destination-based settlement
CST + entry tax + credit blockages
Textile unit in Surat — pre-GST vs post-GST
Pre-GST: Surat weaver paid excise on yarn, state VAT on fabric, and could not fully offset Central tax against state VAT. Tax stacked at each stage — the “cascading effect.” Post-GST: one 12% GST on fabric with Input Tax Credit at every stage. Selling sarees to Rajasthan? IGST replaces multiple border taxes. The final consumer pays one visible tax; intermediaries claim credit on inputs.
What this means for the exam
GST = goods + services + unified credit chain. VAT = goods only, state-level, incomplete inter-state offset.
Understand the difference
From origin to destination
VAT was largely origin-based within states. GST shifted to destination-based taxation — revenue accrues where consumption happens. That is why producing states initially worried about revenue loss, leading to the GST Compensation Cess (2017–2022) and ongoing Council negotiations.
Prelims statement check
“GST replaced only Central indirect taxes; state VAT continues alongside GST.”
Incorrect — Replacement scope
GST subsumed most Central and State indirect taxes including VAT, excise, service tax, and entry tax.
“GST applies to both goods and services under a unified tax structure.”
Correct — Coverage
Core design feature distinguishing GST from VAT.
PYQ Linkage
The GST Council is chaired by the Union Finance Minister and includes state Finance Ministers — correct?
Key Takeaway
GST = unified goods+services + full ITC + dual federal model | VAT = state goods tax with cascading
