Types of Assessment in income Tax act 2025 and Tax Rules 2026
Under the Income-tax Act, 2025, and the corresponding rules, the framework for assessing a taxpayer’s income is divided into several specific types of assessments. Here is a comprehensive breakdown of the types of assessments:
1. Self-Assessment (Section 266) Before furnishing a return of income (whether a regular return, an updated return, or a return in response to a notice), the taxpayer is required to compute and pay their own tax. This self-assessment tax is calculated by determining the total tax on the declared income and reducing it by any advance tax paid, tax deducted or collected at source (TDS/TCS), and any allowable tax reliefs or credits.
2. Regular Assessment (Section 270) Also known as a scrutiny assessment, this occurs after a taxpayer has filed their return. Initially, the return is processed to adjust for arithmetical errors or incorrect claims. If the Assessing Officer considers it necessary to ensure that the taxpayer has not understated their income, computed excessive loss, or under-paid tax, they will serve a notice requiring the taxpayer to produce evidence supporting the return. After hearing the evidence and gathering relevant material, the Assessing Officer passes a written order making an assessment of the total income or loss and determines the exact sum payable or refundable.
3. Best Judgment Assessment (Section 271) The Assessing Officer is empowered to assess the total income or loss “to the best of his judgment” if the taxpayer defaults in their basic obligations. This type of assessment is triggered if a person:
- Fails to furnish a required return of income.
- Fails to comply with a notice to produce accounts or documents.
- Fails to comply with a direction to get their accounts audited or inventory valued. Before completing a best judgment assessment, the Assessing Officer must issue a show-cause notice and give the taxpayer an opportunity to be heard.
4. Income Escaping Assessment / Reassessment (Section 279) If the Assessing Officer has information suggesting that any income chargeable to tax has escaped assessment for any tax year, they can open an income escaping assessment. Under this provision, the officer can assess or reassess the escaped income and recompute the loss or depreciation allowance for the relevant year. This process requires serving a specific notice under Section 280, demanding the taxpayer to furnish a return of income for the year in question.
5. Faceless Assessment (Section 273) To ensure transparency and eliminate physical interface between the taxpayer and the tax authority, assessments (under Section 270), best judgment assessments (under Section 271), and reassessments (under Section 279) are mandated to be conducted in a faceless manner. This is coordinated centrally by a National Faceless Assessment Centre, which assigns cases dynamically to various specialised units, including assessment units, verification units, technical units, and review units.
6. Block Assessment of Search Cases (Section 292 & 294) When a search is initiated or assets/documents are requisitioned by the tax department, the Assessing Officer conducts a special “block assessment”. Instead of a single tax year, this assessment evaluates the total undisclosed income over a “block period,” which consists of the six preceding tax years plus the current period up to the date the search was executed. Pending regular assessments for years falling within this block period are automatically abated.
7. Precautionary / Expedited Assessments The Act also allows the Assessing Officer to immediately assess income during the current tax year itself (rather than waiting for the year to end) in specific situations where tax recovery might be compromised:
- Persons leaving India: If an individual is likely to leave India with no intention of returning, their income from the start of the year up to the probable date of departure is assessed immediately.
- Dissolving bodies: If an association of persons, body of individuals, or artificial juridical person was formed for a particular event and is likely to be dissolved in the same year.
- Tax avoidance transfers: If it appears a person is likely to charge, sell, or alienate their assets to avoid tax liabilities, their income up to that date is assessed immediately.
- Discontinued business: If a business or profession is discontinued or a firm is dissolved, the income from the start of the year up to the date of discontinuance can be assessed at the discretion of the Assessing Officer.
