VAT & GST glossary
Short, plain-English definitions of the terms you meet when calculating VAT.
Net
The price before tax is added. Also called the VAT-exclusive or pre-tax amount.
Gross
The price after tax is added — what the customer pays. Also called the VAT-inclusive amount.
Output VAT
VAT you charge on your own sales and pass on to the tax authority.
Input VAT
VAT you pay on business purchases, which you may be able to reclaim against the output VAT you owe.
Standard rate
The default rate that applies to most goods and services (for example 20% in the UK, 19% in Germany).
Reduced rate
A lower rate applied to specific categories, such as some food, energy or cultural items.
Zero-rated
Charged at 0%, but still a taxable supply — so it counts towards registration thresholds and can be reclaimed differently from exempt items.
Exempt
Outside the scope of VAT. You do not charge VAT, and you usually cannot reclaim input VAT on related costs.
Reverse charge
A rule where the buyer, not the seller, accounts for the VAT — common on cross-border business-to-business services.
CGST / SGST / IGST (India)
Central GST, State GST and Integrated GST. Intra-state sales are typically split equally into CGST and SGST; inter-state sales use IGST.
GST
Goods and Services Tax — the same mechanism as VAT under a different name, used in countries such as India, Australia, Canada, New Zealand and Singapore.
