What is CGST: Full Form, Meaning, Applicability, Rates, Rules, and Calculation

The implementation of goods and services tax (GST) in India was a landmark tax reform that aimed to simplify the country's complex tax structure. Under GST, all indirect taxes were subsumed into three categories: Central goods and services tax (CGST), State goods and services tax (SGST), and integrated goods and services tax (IGST).

In this article, we will delve into the details of CGST, its features, rules, and the documents required for compliance.

What is CGST?

CGST stands for Central Goods and Services Tax, a tax levied by the central government on the intrastate supply of goods and services. It was introduced under the Central Goods and Services Tax Act, 2017, and applies across India, excluding Jammu and Kashmir. CGST replaces previous central taxes such as service tax, central excise duty, and customs duty.

When goods or services are sold within a state, both CGST and SGST (State Goods and Services Tax) are applied. While CGST is collected by the central government, SGST is collected by the respective state government. The overall tax burden is typically shared equally between the state and the central government.

For instance, if a manufacturer in Maharashtra sells goods within the state, both SGST and CGST are applicable. The revenue from SGST goes to the Maharashtra government, while the central government receives the CGST share. Businesses operating within a state often require additional funds to manage working capital or expand their operations. In such cases, they may consider opting for startup business loans to fuel early-stage growth and meet tax obligations efficiently.

Check your business loan eligibility to see what financing options are available to support such operational and compliance needs. The rates of CGST are determined by the GST Council, which meets periodically to review and adjust tax rates. This system simplifies the tax structure, making it easier for businesses to comply with regulations, and ensures a more transparent flow of revenue between the central and state governments.

CGST stands for Central goods and services tax. It is levied by the central government on the intrastate movement of goods and services, i.e., transactions within one state. The Central goods and services tax Act 2017 govern CGST, which applies to the entire country except Jammu and Kashmir. In an intrastate movement, both CGST and SGST are applicable, with the revenues collected going to the central and respective state governments, respectively. For instance, if a manufacturer sells a product within Maharashtra, SGST and CGST will be levied, with revenues shared between the state and central governments.

When is CGST applicable?

CGST (Central Goods and Services Tax) is charged when goods or services are sold within the same state.

For example, if a business in Karnataka sells furniture to a customer who is also in Karnataka, CGST will be applied to that sale.

Along with CGST, an equal amount of SGST (State GST) or UTGST (Union Territory GST) is also charged—depending on whether the sale happens in a state or a union territory.

CGST is collected by the central government, while SGST or UTGST is collected by the state or union territory government where the sale takes place. Check your pre-approved business loan offer to explore funding options that can help streamline such intrastate business operations while ensuring tax compliance.

CGST example

Let’s say a manufacturer in Maharashtra sells goods worth Rs. 10,000 to a retailer within the same state. Under the GST system, two types of taxes apply: CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax). If the total GST rate is 18%, it’s split equally into 9% CGST and 9% SGST.

For this transaction, 9% of Rs. 10,000 is Rs. 900, so the CGST is Rs. 900, and the SGST is also Rs. 900. The manufacturer adds these taxes to the product price, so the retailer pays Rs. 10,000 (for the goods) + Rs. 900 (CGST) + Rs. 900 (SGST), which totals Rs. 11,800.

The Rs. 900 CGST is sent to the central government, while the Rs. 900 SGST goes to the Maharashtra state government. This way, both the central and state governments get their share of the taxes. The GST system makes tax collection simpler and ensures that both state and central governments benefit from sales made within a state.

The key features of the Central Goods and Services Tax (CGST) Act, 2017 are explained below:

• Tax is charged on all supplies of goods and services that take place within the same state (intra-state transactions).
• Businesses can claim input tax credit (ITC) on the GST they pay for goods and services used in the course of running their business, including those intended for future use. This helps reduce the overall tax burden.
• The Act allows registered taxpayers to assess their own tax liabilities. This self-assessment system makes it easier for businesses to calculate and pay their taxes without waiting for government audits.
• The CGST Act also places certain responsibilities on e-commerce operators. These platforms must collect tax at the source—up to 1% of the value of taxable sales made through their portal—on behalf of sellers using their platforms.
• It gives tax authorities the power to conduct audits of registered businesses to ensure they are complying with the law and paying the correct amount of tax.
• The Act empowers tax officers to carry out inspections, searches, seizures, and arrests in cases where they suspect tax evasion or non-compliance.
• If a taxpayer fails to pay the required taxes, the government can recover the money through several methods. This may include holding or selling the person’s goods, or taking over their movable and immovable property.
• It includes clear rules for handling cases where businesses break the law, including penalties for non-compliance or misconduct.
• The Act provides guidelines for the smooth transition of existing taxpayers from the old tax system to GST. This helps avoid confusion and ensures continuity in tax payments.

• Lastly, the CGST Act includes an anti-profiteering rule. This ensures that if a business gains any benefit from reduced tax rates under GST, it must pass that benefit on to the customer in the form of lower prices.

  
  

CGST rules

The CGST Act requires businesses to adhere to certain rules, including:

1. Composition scheme: Businesses registered under the GST composition scheme must issue a supply bill.
2. Invoice: Registered businesses must issue a tax invoice for taxable goods and services, each carrying a unique serial number.
3. Equal CGST and SGST: CGST and SGST are levied in equal amounts, leading to a combined GST rate. For example, an 18% GST rate would entail 9% CGST and 9% SGST.

Following a significant GST reform and rate rationalisation, the Central Goods and Services Tax (CGST) framework has been streamlined into two primary slabs — 5% and 18% — along with a 0% (exempt) rate for essential items and a new 40% rate for specific luxury and sin goods. The earlier 12% and 28% slabs have largely been removed.

The revised CGST slabs (effective from 22 September 2025) are as follows:
