Self-Assessment and Intimation for CMA Inter

Self-assessment means you compute your tax, add interest and fee where due, deduct TDS, TCS, advance tax and relief, pay the balance, and then file the return. The department processes the return and sends an intimation, with limited adjustments and any refund. If the return is selected, scrutiny assessment under the Income-tax Act, 2025 follows. Solve questions in that order.

What this chapter covers

This chapter follows a return from your desk to the department and back. First you work out your own tax, add any interest and fee that apply, deduct the prepaid taxes and pay the balance before filing. Then the return is processed by the department, who send you an intimation showing tax, interest, fee and refund. Finally, some returns are picked for a detailed check, which is scrutiny assessment under the Income-tax Act, 2025.

The chapter is procedural, so it rewards clear sequence and precise conditions. You need to know what is credited (TDS, TCS, advance tax, relief), what interest or fee can be added, which adjustments the processing officer may make without a detailed enquiry, and what the officer must do before making them.

It connects to the rest of the Taxation paper at both ends. The tax you pay here comes from your computation of total income and from the chapters on TDS, TCS and advance tax. What you learn here about returns, interest and refunds also feeds the chapters on appeals, penalties and procedures. Treat it as the link between computing tax and dealing with the department.

The chapter is short and rule-based, so it is an efficient place to pick up marks in both the 15 objective questions and the written section. Objective questions test one condition at a time, such as which adjustments are allowed on processing. Written questions ask you to compute the self-assessment tax payable or the refund due, and to explain the process. If you learn the sequence and the exact conditions, you can answer both types with little risk.

Self-Assessment and Intimation: topics in the order to study them

  1. 1Self-Assessment of Tax and Payment Before FilingStart here because it is the first step in the process and uses the tax computation you already know, with interest and fee added and credit given for TDS, TCS, advance tax and relief.
  2. 2Summary Assessment and Intimation of Return ProcessingNext, learn what happens after filing: how the return is processed and what the intimation tells you.
  3. 3Adjustments Permitted and Refunds on ProcessingStudy this after processing, because the permitted adjustments and the refund calculation are decided during processing and depend on how it works.
  4. 4Scrutiny and Other Assessment Under the Income-tax Act, 2025Finish with the detailed assessment, as it is easier to follow once you know what processing does not cover.

How to prepare Self-Assessment and Intimation

Prepare this chapter as a flow of steps with conditions attached, then practise it with small numerical problems.

  1. Draw a one-page flowchart: compute tax, add interest and fee, credit prepaid taxes, pay balance, file return, processing, intimation, refund or demand, scrutiny.
  2. Read the self-assessment topic and practise the arithmetic: total tax, add interest for default in furnishing the return, interest for default in payment of advance tax, interest for deferment of advance tax, and fee for late filing, then subtract TDS, TCS, advance tax and relief to find the balance payable or refundable. Check the section numbers of these interest and fee provisions in the Income-tax Act, 2025 text.
  3. List the permitted adjustments on processing in your own words, one line each, with the condition for each. Check the exact list in the Income-tax Act, 2025 text.
  4. Note what must happen before an adjustment is made, and what the taxpayer can do on receiving an intimation.
  5. Study scrutiny assessment under the Income-tax Act, 2025 as a separate block: when it applies, what the officer can do, and how it differs from processing.
  6. Solve past MCQs on each topic, then write two or three full written answers with a heading, the rule, the calculation and a short conclusion.
  7. Before the exam, revise the flowchart and the adjustment list without looking at your notes.

Common mistakes in Self-Assessment and Intimation

  • Confusing processing of the return with scrutiny assessment.

Self-Assessment and Intimation: frequently asked questions

What is self-assessment tax?

It is the tax, interest and fee payable on your return after crediting TDS, TCS, advance tax and relief. You add interest for default in furnishing the return and for default or deferment of advance tax, and the fee for late filing, to the tax, and then deduct the credits. You pay the balance before filing the return.

What is an intimation after processing?

It is the communication from the department after it processes your return. It shows the tax, interest and fee computed, and states whether a refund is due or a further amount is payable.

Can the officer change my return during processing?

Only for the adjustments the Act permits, such as correcting arithmetical errors or apparent incorrect claims. Learn the list and its conditions from the Act, and note the requirement to inform the taxpayer before adjustments.

How is scrutiny assessment different from processing?

Processing is a limited, mostly automated check of the return. Scrutiny assessment under the Income-tax Act, 2025 is a detailed assessment where the officer examines the return and the supporting evidence.
