1. Self Assessment
The assessee himself determines the income tax payable. The tax department has made available various forms for filing income tax return. The assessee consolidates his income from various sources and adjusts the same against losses or deductions or various exemptions if any, available to him during the year. The total income of the assessee is then arrived at. The assessee reduces the TDS and Advance Tax from that amount to determine the tax payable on such income. Tax, if still payable by him, is called self assessment tax and must be paid by him before he files his return of income. This process is known as Self Assessment.
2. Summary Assessment
It is a type of assessment carried out without any human intervention. In this type of assessment, the information submitted by the assessee in his return of income is cross-checked against the information that the income tax department has access to. In the process, the reasonableness and correctness of the return are verified by the department. The return gets processed online, and adjustment for arithmetical errors, incorrect claims, and disallowances are automatically done. Example, credit for TDS claimed by the taxpayer is found to be higher than what is available against his PAN as per department records. Making an adjustment in this regard can increase the tax liability of the taxpayer.
After making the aforementioned adjustments, if the assessee is required to pay tax, he will be sent an intimation under Section 143(1). The assessee must respond to this intimation accordingly. Here you can read a more detailed article on Section 143(1).
3. Regular Assessment
The income tax department authorizes the Assessing Officer or Income Tax authority, not below the rank of an income tax officer, to conduct this assessment. The purpose is to ensure that the assessee has neither understated his income or overstated any expense or loss or underpaid any tax.
The CBDT has set certain parameters based on which a taxpayer’s case gets picked for a scrutiny assessment.
a. If an assessee is subject to a scrutiny assessment, the Department will send a notice well in advance. However, such notice cannot be served after the expiry of 6 months from the end of the Financial year, in which return is filed.
b. The assessee will be asked to produce the books of accounts, and other evidence to validate the income he has stated in his return. After verifying all the details available, the assessing officer passes an order either confirming the return of income filed or makes additions. This raises an income tax demand, which the assessee must respond to accordingly.
4. Best Judgement Assessment
This assessment gets invoked in the following scenarios:
a. If the assessee fails to respond to a notice issued by the department instructs him to produce certain information or books of accounts
b. If he/she fails to comply with a Special Audit ordered by the Income tax authorities
c. The assessee fails to file the return within due date or such extended time limit as allowed by the CBDT
d. The assessee fails to comply with the terms as contained in the notice issued under Summary Assessment
After providing an opportunity to hear the assessee’s argument, the assessing officer passes an order based on all the relevant materials and evidence available to him. This is known as Best Judgement Assessment.
5. Income Escaping Assessment
When the assessing officer has sufficient reasons to believe that any taxable income has escaped assessment, he has the authority to assess or reassess the assessee’s income. The time limit for issuing a notice to reopen an assessment is 4 years from the end of the relevant assessment Year. Some scenarios where reassessment gets triggered are given below.
a. The assessee has taxable income but has not yet filed his return.
b. The assessee, after filing the income tax return, is found to have either understated his income or claimed excess allowances or deductions.
c. The assessee has failed to furnish reports on international transactions, where he is required to do so.
Assessment could close quickly for some taxpayers, while it could prove to be quite gruelling for others. If you are not comfortable dealing with income tax officers, it is suggested that you take the help of a Chartered Accountant to help you with your case.
