The set of standard rate brackets under the Goods and Services Tax, into which goods and services are classified so that essentials are taxed low and luxury or "demerit" goods are taxed high.
The number and broad values of slabs, the compensation cess on demerit goods, and the GST Council's role in setting rates are common indirect-tax facts.
The 28 percent slab is the standard top rate, but the compensation cess pushes the effective burden on luxury and sin goods higher; exempt (nil-rated) is not the same as zero-rated (zero-rated allows input credit, typically on exports).
Multi-slab structure (0, 5, 12, 18, 28 percent) plus a cess on luxury and sin goods, set by the GST Council; verify the latest rates.
