Income Tax Assessment Order — 143(1), 143(3) & 148

No. A 143(1) intimation is an automated, routine processing summary that almost every return generates — it is not an audit. Scrutiny begins only with a separate Section 143(2) notice served by the Assessing Officer. Getting a 143(1) does not mean your return has been picked for detailed examination.

CPC can issue a 143(1) intimation up to 9 months from the end of the financial year in which the return was filed. If no intimation is issued within that period, the return as filed is treated as the intimation and is deemed processed.

A mismatch arises when the TDS or tax credit you claimed in the ITR differs from what appears in Form 26AS / AIS. Common causes are a deductor filing a late or wrong TDS return, quoting the wrong PAN, or you claiming credit before it reflected in 26AS. Reconcile 26AS/AIS with your ITR and, if needed, file a rectification under Section 154.

Log in to incometax.gov.in, open e-Proceedings under Pending Actions, select the notice and submit a detailed written reply with supporting documents — bank statements, invoices, Form 26AS, AIS, capital-gains statements and any deeds relevant to the issues raised. Respond within the deadline in the notice (often 15-30 days); extensions can be requested through the portal.

A Section 143(2) notice must be served within 3 months from the end of the financial year in which the return was filed. A notice served after this limit is invalid, and any assessment based on it can be challenged.

It is the final assessment order the Assessing Officer passes after completing scrutiny under 143(2). It determines your total income and tax liability. If the AO makes additions or disallows claims, the extra tax is demanded through a Section 156 notice. You can appeal to the Commissioner (Appeals) within 30 days.

Under Section 144B, most scrutiny assessments are conducted faceless through the National Faceless Assessment Centre — there is no physical meeting with an officer, work is allocated randomly, and all communication happens electronically through the portal. It is designed to reduce discretion and increase transparency.

A Section 148 notice is issued when the Assessing Officer has information suggesting income chargeable to tax escaped assessment in a past year. Before it, the AO must issue a Section 148A show-cause notice and give you an opportunity to explain. In response to 148 you must file a fresh return for that year within the time allowed.

After the Finance Act, 2024 rationalisation (from 1 September 2024), reassessment can generally be initiated up to 3 years from the end of the relevant assessment year, extended to about 5 years where the escaped income represented by an asset or specific entries is above ₹50 lakh, with sanction of the specified authority. Older notices may still follow the earlier regime with a 10-year outer limit.

Section 148A is the mandatory pre-reassessment stage: the AO shares the information suggesting escaped income and gives you at least 7 days (extendable) to respond, then passes a reasoned order deciding whether it is a fit case to issue a 148 notice. It ensures you get a hearing before the year is re-opened.

Ignoring notices can lead to a best-judgment assessment under Section 144, where the AO estimates your income from available data — usually resulting in a higher demand. Penalty under Section 270A for under-reporting or misreporting, and in serious cases prosecution, can also follow. Always respond within the stipulated deadline, even if only to seek an extension.

A regular scrutiny assessment under Section 143(3) must generally be completed within 12 months from the end of the assessment year in which the income was first assessable, subject to specified extensions. Faceless assessment follows the same outer time limits administered through the National Faceless Assessment Centre.

A Section 156 notice communicates the tax, interest, penalty or other sum payable as a result of an assessment or intimation. It must generally be paid within 30 days of service. Non-payment attracts interest under Section 220 and recovery action; if you dispute the demand, file an appeal and, where eligible, apply for a stay of demand.

Every valid notice or order carries a Document Identification Number (DIN). Use the "Authenticate Notice/Order Issued by ITD" service on incometax.gov.in to verify the DIN before acting. Real notices also appear under e-Proceedings when you log in — a communication that has no DIN and does not appear in your portal account should be treated with caution.

Yes. If you disagree with a 143(3) or 144 order you can file an appeal to the Commissioner of Income Tax (Appeals) in Form 35 within 30 days of receiving the order, and escalate further to the ITAT if needed. For a plain apparent error in a 143(1) or order, a rectification under Section 154 is the faster route.
