Different types of GST Assessments

Assessment under GST refers to the process of determining the tax liability of a registered or liable person under the GST law. It is an important mechanism to ensure that the correct amount of tax is paid to the government and that taxpayers comply with the provisions of the CGST Act. The GST law provides for different types of assessments to address various situations faced by taxpayers, ranging from self-declared liabilities to assessments initiated by tax authorities.

A) Self-Assessment (Section 59 of CGST Act)

Self-assessment is the basic and most commonly followed method of assessment under GST. Every registered taxpayer is required to assess their own tax liability while filing prescribed GST returns such as GSTR-1, GSTR-3B and annual returns. Under this system, the taxpayer determines the value of taxable supplies, applicable tax rates, eligible input tax credit and the amount of tax payable. The tax department does not interfere at this stage, making GST a trust-based and compliance-driven taxation system.

Different types of GST Assessments

Example: ABC Traders, a registered GST dealer, sells goods worth ₹10,00,000 in April at a GST rate of 18%.

  • Output GST = ₹1,80,000
  • Input Tax Credit (ITC) available = ₹1,20,000

ABC Traders calculates its own tax liability:₹1,80,000 - ₹1,20,000 = ₹60,000

The trader files GSTR-1 and GSTR-3B and pays ₹60,000 as GST.

No involvement of the tax officer takes place at this stage.

This is a self-assessment, as the taxpayer themselves determines and pays the tax.

B) Provisional Assessment (Section 60)

Provisional assessment is applicable in cases where a taxpayer is unable to determine the correct value of supply or the applicable tax rate. In such situations, the taxpayer may request permission from the tax officer for provisional assessment. The officer may allow payment of tax on a provisional basis subject to execution of a bond and furnishing of security. Once the issue is resolved, a final assessment is carried out within the prescribed time limit, and any excess or short payment of tax is adjusted accordingly.

Example: XYZ Ltd manufactures a new product but is unsure whether it should be taxed at 12% or 18% under GST.

XYZ Ltd applies to the GST officer for a provisional assessment. The officer allows tax payment at 12% provisionally after XYZ Ltd submits a bond and security.

Later, it is finalized that the correct rate is 18%.XYZ Ltd then pays the differential tax (6%) along with applicable interest.

This situation is an example of provisional assessment, used when value or tax rate is uncertain.

C) Scrutiny Assessment (Section 61)

Scrutiny assessment involves examination of returns filed by the taxpayer to verify their correctness. Under this type of assessment, the tax officer scrutinizes the returns and identifies discrepancies such as mismatch of data, incorrect tax payment or excess claim of input tax credit. If discrepancies are found, a notice is issued seeking explanation from the taxpayer. If the explanation is satisfactory, no further action is taken; otherwise, the matter may proceed to audit or demand proceedings.

 

Example: A GST officer examines the returns of PQR Enterprises and notices that:

ITC claimed in GSTR-3B is higher than ITC shown in GSTR-2B.

The officer issues a notice asking PQR Enterprises to explain the difference.PQR submits proper invoices and reconciles the mismatch.

Since the explanation is satisfactory, no further action is taken.This process is called scrutiny assessment, where returns are checked for correctness.

D) Best Judgement Assessment (Sections 62 & 63)

Best judgement assessment is carried out when a taxpayer fails to comply with statutory requirements. Under Section 62, it applies to registered persons who do not file returns even after receiving notice, while under Section 63, it applies to unregistered persons who are liable to pay tax but fail to obtain registration. In such cases, the tax officer determines the tax liability based on available information and past records. This assessment serves as a deterrent against non-compliance and encourages timely filing of returns.

Section 62 - Registered Person

Example: LMN Traders is registered under GST but has not filed returns for 6 months despite receiving notices.

The GST officer estimates the tax liability based on past returns and available data and issues an assessment order. This is best judgement assessment under Section 62.

Section 63 - Unregistered Person

Example: Mr. Ramesh is running a business with turnover exceeding the GST registration limit but has not taken GST registration.

The officer identifies the liability and assesses tax based on market data and business records. This is best judgement assessment under Section 63.

E) Summary Assessment (Section 64)

Summary assessment is a special provision intended to protect the interest of revenue in urgent situations. It is initiated when the tax officer has sufficient grounds to believe that delay in assessment may adversely affect tax recovery. With prior approval from a higher authority, the officer can immediately assess the tax liability. This type of assessment is generally used in cases involving fraud, tax evasion or perishable goods, though the affected person has the right to apply for withdrawal of such assessment.

Example No.
