Detailed Tax Breakdown for Contractors

Composition Scheme vs Regular Scheme

Contractors in India can opt for either the composition scheme or the regular scheme. The composition scheme is available for contractors with an annual turnover of up to ₹1.5 crores, and it requires them to pay a fixed percentage of their turnover as GST.

The regular scheme, on the other hand, requires contractors to pay GST on the value of their services, and they can claim input tax credit (ITC) on the goods and services used in their business.

The following table compares the two schemes:

Scheme	GST Rate (%)	ITC Eligibility	Annual Turnover Limit
Composition Scheme	1-5	No	₹1.5 crores
Regular Scheme	18	Yes	No limit

Comparison with Pre-GST Tax Regime

Service Tax vs GST

Before the introduction of GST, contractors in India were required to pay service tax on their services. The service tax rate was 15%, and it was levied on the value of the services provided.

The following table compares the service tax rate with the GST rate:

Tax Type	Tax Rate (%)	Effective Date
Service Tax	15	June 1, 2015
GST	18	July 1, 2017

The GST rate is higher than the service tax rate, but it provides more comprehensive coverage, including the taxation of goods and services.
