Best Judgment Assessment Under Section 144 — When It Applies, Process & Remedies

Best Judgment Assessment Under Section 144: When It Applies, Process, and Remedies

A best judgment assessment under Section 144 is an assessment the Assessing Officer makes on their own estimate of a taxpayer's income, when the taxpayer has failed to cooperate. It is what happens when a return is not filed or a notice is ignored: rather than let the matter lapse, the officer proceeds to assess the income to the best of their judgment, using whatever material is available. Because the taxpayer has not put their own case forward, the estimate is usually higher than it would otherwise be, and the outcome is often an inflated demand. Understanding when Section 144 applies, and responding before it does, is the key to avoiding an assessment made without your side of the story.

N D Savla & Associates is a firm of Chartered Accountants in Mumbai that helps taxpayers handle best judgment assessments, from responding to the notice that precedes them to challenging an assessment already made. This guide explains what a Section 144 assessment is, the situations that trigger it, the opportunity the taxpayer must be given, the requirement that the estimate be fair rather than arbitrary, the consequences, and how the assessment can be challenged. It sits alongside our work on regular scrutiny assessments and tax appeals.

The focus here is practical: avoiding a best judgment assessment by responding in time, and, where one has been made, getting it corrected.


What Is a Best Judgment Assessment Under Section 144?

A best judgment assessment is an assessment made by the Assessing Officer to the best of their judgment, based on the material and information available, where the taxpayer has not filed a return or has not complied with the notices in the assessment. It is, in effect, a one-sided assessment: the officer determines the income without the taxpayer's own figures and explanations, because those have not been provided. The law allows this so that a taxpayer cannot defeat the assessment simply by staying silent.

The defining feature of a best judgment assessment is that it rests on the officer's estimate rather than on the taxpayer's return. That estimate is drawn from whatever is on record, such as past returns, third-party information, and the material the department holds. Because it is an estimate made in the taxpayer's absence, it tends to be on the higher side, which is precisely why it is in the taxpayer's interest to engage before the assessment is made.


When Section 144 Is Invoked

A best judgment assessment is triggered by a failure to file or a failure to comply. The main situations are set out below.

TriggerThe default
No return is filedThe taxpayer fails to file the return required under Section 139 and does not file it in response to a notice
A notice under 142(1) is ignoredThe taxpayer fails to comply with a notice calling for accounts, documents, or information
A special audit direction is ignoredThe taxpayer fails to comply with a direction for a special audit under Section 142(2A)
A scrutiny notice is ignoredThe taxpayer fails to comply with a notice under Section 143(2)

The Opportunity of Being Heard

The law does not let the Assessing Officer make a best judgment assessment without warning. As a rule, before completing an assessment under Section 144, the officer must give the taxpayer an opportunity of being heard, by issuing a show-cause notice asking why the assessment should not be completed to the best of judgment. This is the taxpayer's chance to step in, file the return or the information, and explain the position, and it is often the last opportunity to avoid an ex-parte assessment. There is one exception: this opportunity is not required where a notice under Section 142(1) had already been issued and the taxpayer had not complied with it.

You usually get a show-cause notice first: Before making a best judgment assessment, the Assessing Officer must ordinarily give the taxpayer an opportunity to be heard, through a show-cause notice asking why the assessment should not be completed to the best of judgment. This opportunity is not required where a notice under Section 142(1) had already been issued and ignored. Responding to the show-cause notice is often the last chance to avoid an ex-parte assessment.

Best Judgment Does Not Mean Arbitrary

There is an important safeguard for the taxpayer even in a best judgment assessment. Best judgment does not mean the officer can assess any figure they like. The estimate must be a fair and honest one, based on the material available, the taxpayer's past records, the nature of the business, and reasonable inference. The officer cannot assess arbitrarily, vindictively, or on pure guesswork, and must apply their mind to the facts on record. An assessment made without any reasonable basis, or that is capricious, can be challenged on appeal and set aside or reduced. So while a best judgment assessment is a serious matter, it is not a licence for an unreasonable demand.

Best judgment is not the same as arbitrary: A best judgment assessment must be a fair and honest estimate, based on the material available, the taxpayer's past records, and reasonable inference. The Assessing Officer cannot assess arbitrarily, vindictively, or on pure guesswork. An assessment made without any reasonable basis can be challenged on appeal, which is an important protection for the taxpayer.

The Process Step by Step

A best judgment assessment typically develops as follows:

  1. The default. The taxpayer fails to file a return, or fails to comply with a notice under Section 142(1) or 143(2).
  2. Show-cause notice. The Assessing Officer issues a show-cause notice giving the taxpayer an opportunity to explain, except where a 142(1) notice was already ignored.
  3. The taxpayer's response. The taxpayer may still file the return or the information and put their case, which can avert or improve the assessment.
  4. Gathering material. The officer gathers the relevant material on record, such as past returns and third-party information, faceless through the assessment system.
  5. The best judgment assessment. The officer completes the assessment on a fair estimate of the income, to the best of their judgment.
  6. Demand and remedies. A demand follows under Section 156, and the taxpayer can challenge the assessment on appeal.

Consequences of a Best Judgment Assessment

A best judgment assessment carries several consequences, most of them adverse.

ConsequenceWhat it means
Higher assessed incomeThe income is estimated by the officer, usually to the taxpayer's disadvantage
Tax demand and interestA demand is raised under Section 156, with interest for the default
PenaltyPenalty for underreporting of income, and for non-compliance with the notices
ProsecutionIn cases of wilful failure to file a return, prosecution can follow

How to Avoid a Best Judgment Assessment

The best defence against Section 144 is not to trigger it. In practice that means:

  • File your return on time. A filed return removes the most common ground for a best judgment assessment.
  • Respond to every notice. Notices under Section 142(1) and 143(2) must be complied with within the time given.
  • Answer the show-cause notice. If a show-cause notice is issued, respond promptly with the return or the information sought.
  • Keep your records ready. Maintaining books, bank statements, and supporting documents lets you respond quickly and fully.
  • Get professional help early. Engaging a professional as soon as a notice arrives is the surest way to avoid an ex-parte assessment.

Remedies Against a Best Judgment Assessment

A best judgment assessment is not the end of the road. Where one has been made, the taxpayer can challenge it by filing an appeal to the Commissioner of Income Tax (Appeals), arguing that the estimate is excessive or without basis and placing the correct facts and figures on record. If the first appeal does not resolve it, the matter can be taken to the Income Tax Appellate Tribunal. In appropriate cases, a rectification of an apparent mistake can also be sought. The key is to move quickly, since the appeal has its own deadline, and to bring the records that were not before the officer to the appellate authority.


Documents Needed

Responding to or challenging a best judgment assessment draws on:

  • The return and computation, the income tax return for the year, or the return being filed in response.
  • Financial records, the books of account, bank statements, and financial statements for the year.
  • Supporting documents, invoices, vouchers, and evidence for the income and the expenses.
  • The notices and the order, the show-cause notice, the assessment order, and the notice of demand.
  • Reconstructed records where needed, rebuilt books and statements where the originals are incomplete.

How We Help With a Section 144 Assessment

We help both before and after a best judgment assessment, to avoid it where possible and to correct it where it has been made.

  1. Case review. We analyse the assessment order or the show-cause notice and identify the issues and the assumptions made.
  2. Response preparation. We prepare the return, explanations, and submissions to put the taxpayer's case.
  3. Record reconstruction. Where records are incomplete, we help rebuild the financial records needed to support the case.
  4. Representation. We represent the taxpayer before the Assessing Officer and handle the queries and clarifications.
  5. Appeal where needed. Where the assessment stands or is excessive, we file and argue the appeal to have it corrected.
  6. Closure. We work towards a fair and compliant resolution, with the demand brought down to the correct figure.

Common Mistakes

A few avoidable errors lead to or worsen a best judgment assessment:

  • Ignoring the notices. Not filing the return or responding to notices is what triggers a best judgment assessment in the first place.
  • Missing the show-cause notice. Failing to respond to the show-cause notice forfeits the last chance to avoid an ex-parte assessment.
  • Accepting an excessive estimate. Not challenging an inflated or baseless assessment leaves an unfair demand standing.
  • Delaying the appeal. The appeal against the assessment has a strict deadline that must not be missed.
  • Not reconstructing records. Failing to rebuild incomplete records leaves the taxpayer unable to prove the correct income.

Why Taxpayers Choose N D Savla & Associates

A best judgment assessment is best dealt with before it is made, and can still be corrected after. We work on both fronts. When a notice or a show-cause notice arrives, we respond quickly, filing the return and putting the taxpayer's case to head off an ex-parte assessment. Where an assessment has already been made, we review it, reconstruct the records where they are incomplete, and challenge an excessive or baseless estimate on appeal, bringing the correct facts before the authorities. Our aim throughout is a fair assessment based on the real income, not an inflated one made in the taxpayer's absence. For a taxpayer facing Section 144, this means the case handled quickly and the demand brought down to what it should be.

Frequently Asked Questions — Section 144

What is Section 144?
Section 144 provides for a best judgment assessment, made by the Assessing Officer to the best of their judgment based on the available material, where the taxpayer has failed to file a return or to comply with the notices in the assessment. Because it is made without the taxpayer's own figures, the estimated income is usually higher, so it is in the taxpayer's interest to engage before it is made.
When is Section 144 applied?
It is applied when the taxpayer fails to file the return required under Section 139, fails to comply with a notice under Section 142(1) calling for information, fails to comply with a direction for a special audit under Section 142(2A), or fails to comply with a scrutiny notice under Section 143(2). In each case, the officer can proceed to a best judgment assessment.
Does the officer have to give me a chance before a Section 144 assessment?
Yes, as a rule. Before making a best judgment assessment, the Assessing Officer must give the taxpayer an opportunity to be heard through a show-cause notice. The one exception is where a notice under Section 142(1) had already been issued and the taxpayer had not complied with it, in which case the further opportunity is not required.
Can the officer assess any figure in a best judgment assessment?
No. A best judgment assessment must be a fair and honest estimate based on the material available, the taxpayer's past records, and reasonable inference. The officer cannot assess arbitrarily, vindictively, or on pure guesswork. An assessment made without any reasonable basis can be challenged on appeal and set aside or reduced.
Can a Section 144 assessment be challenged?
Yes. A best judgment assessment can be challenged by filing an appeal to the Commissioner of Income Tax (Appeals), and, if needed, further to the Income Tax Appellate Tribunal, arguing that the estimate is excessive or without basis and placing the correct facts on record. A rectification of an apparent mistake may also be available in suitable cases.
What documents are required to handle a Section 144 case?
The main documents are the income tax return and computation, the financial records such as the books of account and bank statements, and the supporting invoices and vouchers, along with the show-cause notice, the assessment order, and the notice of demand. Where records are incomplete, they may need to be reconstructed to support the correct income.
What are the consequences of a best judgment assessment?
The assessed income is usually higher, leading to a tax demand under Section 156 with interest for the default, and penalties can follow both for underreporting of income and for non-compliance with the notices. In cases of wilful failure to file a return, prosecution is also possible, which is why the situation should be dealt with promptly.
How can the tax liability be reduced in a Section 144 case?
By engaging with the assessment and putting the correct facts before the authorities: filing the return, submitting the financial records and evidence, and correcting the assumptions the officer made in the taxpayer's absence. Where the assessment stands or is excessive, the estimate can be challenged on appeal, so that the demand is brought down to the real figure.
