Section 144 Best Judgment Assessment: Causes, Consequences and Appeal Guide
There is a pattern that leads to a Section 144 order, and it almost always looks the same. A notice arrives. It gets ignored because it looks like junk mail, or because life got busy, or because the taxpayer assumed someone else was handling it. Then another notice arrives. That one gets ignored too. Eventually, the Assessing Officer stops waiting and completes the assessment without you.
That is what Section 144 is. It is the Income Tax Department's answer to silence.
The resulting order is called a Best Judgment Assessment. It is not based on your actual income, your books, or your explanations, because you didn't provide any of that. It is based on whatever information the AO could gather from third-party sources, past returns, and their own estimate of what your income should be. And because the AO is working without your input, those estimates are almost never in your favour.
The important thing to understand right now is this: a Section 144 order is not the end of the road. It can be challenged. But the window to act is 30 days, and it starts the moment the demand notice is served.
What Is a Best Judgment Assessment Under Section 144?
Section 144 of the Income Tax Act empowers an Assessing Officer to complete an assessment on their own, using their best judgment, when a taxpayer fails to cooperate with the assessment process. The technical term for this is an ex parte assessment, meaning it is done on one side only, without the taxpayer's participation.
The law does not allow the AO to act arbitrarily. The judgment must be based on available material, must be fair and reasonable, and must have some factual foundation. An AO cannot simply invent numbers. What they can do is use GST data, AIS entries, bank information, TDS records, third-party reports, and previous years' income as reference points, then estimate your income in the absence of any explanation from you.
The difference between a 143(3) scrutiny assessment and a 144 best judgment assessment is cooperation. In a 143(3) assessment, you participated, submitted documents, and the AO made a determination based on the full picture. In a 144 assessment, the full picture was built without you.
Section 144 is described in the law as procedural rather than punitive. It exists so that the tax administration does not come to a standstill because a taxpayer chose not to respond. But in practice, the consequences for the taxpayer are significant.
When Can the AO Invoke Section 144?
The AO can pass a best judgment assessment in the following situations:
1. You did not file your income tax return under Section 139(1), 139(4), 139(5), or 139(8A), despite being required to do so.
2. You did not comply with a Section 142(1) notice asking you to file your return or produce specific documents and accounts.
3. You did not comply with Section 142(2A) directions requiring a special audit of your accounts.
4. You did not respond to a Section 143(2) scrutiny notice after your return was selected for examination.
5. The AO rejected your books of account under Section 145(3), finding them incomplete, inaccurate, or not maintained according to a consistent accounting method. Even if you filed a return and cooperated, if your books cannot be trusted, the AO can set them aside and estimate income independently.
The last trigger is one that many people overlook. You can file your return, respond to notices, and still face a Section 144 order if the AO decides your books of account do not present a reliable picture of your income.
The Process Before a Section 144 Order Is Passed
This is a critical point that many guides miss. A best judgment assessment is not automatic or silent. The law requires the AO to give you one final opportunity before passing the order.
Before completing the assessment, the AO must serve a show-cause notice, asking you to explain your non-compliance and giving you a last chance to submit the required information or returns. Only if your response to this show-cause is inadequate, or if you still do not respond, can the AO proceed to pass the Section 144 order.
This show-cause notice is important for two reasons. First, it gives you a genuine opportunity to prevent the order. Second, if the AO skips this step, the resulting order is procedurally defective and can be successfully challenged on that ground alone.
So if you have received a show-cause notice from an AO citing Section 144, act immediately. This is your last chance before the assessment is finalised without you.
What the AO Uses to Estimate Your Income
When completing a best judgment assessment, the AO draws on whatever legitimate sources are available:
Annual Information Statement (AIS) and Form 26AS: These show bank credits, TDS deductions, property registrations, high-value transactions, and third-party reported income. If your AIS shows credits of ₹40 lakh and you have no explanation on record, the AO may treat that as income.
GST returns: For business assessee, GSTR filings provide turnover data that the AO can use to estimate business income.
Previous years' returns: If you filed returns in prior years, the AO may use those as a baseline and apply growth assumptions.
Industry benchmarks and profit margins: For businesses in specific sectors, the AO may apply standard gross profit margins to estimate income from known revenue.
Bank statements and third-party data: Any information received from banks, employers, or other third parties through surveys or requisitions under Section 133(6).
The combination of these sources allows the AO to construct an estimate of your income. It may or may not reflect your actual situation. Because you were not in the room, it almost certainly overstates your liability.
What a Section 144 Order Typically Contains
Once the assessment is complete, the AO passes an order that includes:
An estimated total income figure, usually significantly higher than what you would have declared, a tax demand calculated on that estimated income, interest under Section 234A (for late filing), Section 234B (for short advance tax), and Section 234C (for deferred instalments), and initiation of penalty proceedings, typically under Section 270A for underreporting or under Section 271(1)(b) for failure to comply with notices.
A demand notice under Section 156 follows shortly after the assessment order. This notice gives you 30 days to pay the demand. And this is when the 30-day appeal clock also starts running.
The order and demand will appear in your income tax portal account. You will also receive communication on your registered email and mobile number.
How to Challenge a Section 144 Assessment Order
A best judgment assessment order is fully appealable. You are not stuck with it.
Step 1: File an appeal before CIT(A) under Section 246A
The Commissioner of Income Tax (Appeals) is the first appellate authority. You must file your appeal within 30 days from the date the Section 156 demand notice was served. Missing this deadline is serious, though the law allows condonation of delay if you have a sufficient reason.
The appeal is filed using Form 35 on the income tax portal. You will need to state the grounds of appeal clearly, pay the prescribed appeal fee, and upload supporting documentation.
Step 2: Present your case with complete documentation
Here is something important that many taxpayers do not know: at the CIT(A) appeal stage, you can present all the documents and explanations you failed to provide during the assessment. The appellate process gives you a fresh hearing. You can show your actual income, your actual deductions, your books, your bank reconciliation, everything. The CIT(A) is not bound by what the AO assumed.
Many best judgment assessments are substantially reduced or set aside at the appeal stage, particularly when the taxpayer can demonstrate that the non-compliance was not deliberate and that their actual income was different from the AO's estimate.
Step 3: Request a stay of demand pending appeal
A best judgment order can carry a great demand. If you cannot pay the full amount, you can apply for a stay of demand while your appeal is pending. Typically, the department expects a deposit of 20% of the disputed demand as a condition for a stay. Submit a written stay application to the AO simultaneously with filing the CIT(A) appeal.
Step 4: Further appeal options
If the CIT(A) decision is still not in your favour, you can appeal to the Income Tax Appellate Tribunal (ITAT). If the AO acted in violation of natural justice (for example, passed the Section 144 order without giving a show-cause notice), a writ petition before the High Court is also an option.
The time limit for completing a best judgment assessment is 12 months from the end of the relevant assessment year. For AY 2025-26, the deadline is 31 March 2027.
People Also Ask: Section 144 Best Judgment Assessment
What is the difference between Section 143(3) and Section 144 assessment? A Section 143(3) scrutiny assessment is conducted with the taxpayer's participation. The taxpayer submits documents and explanations, and the AO passes an order based on that material. A Section 144 best judgment assessment is done without the taxpayer's input because they failed to comply with notices. The AO estimates income using available third-party data and its own judgment.
Can the AO pass a Section 144 order without any prior notice? No. Before passing a best judgment assessment, the AO must give the taxpayer a final opportunity to be heard through a show-cause notice. An order passed without this step is procedurally defective and can be challenged on that ground.
How do I appeal a Section 144 order? File Form 35 on the income tax portal before the Commissioner of Income Tax (Appeals) within 30 days from the date of the Section 156 demand notice. State your grounds of appeal, pay the appeal fee, and attach supporting documents.
Can I submit documents at the appeal stage that I didn't submit during assessment? Yes. The CIT(A) appeal is a fresh hearing. You can present all the documents, accounts, and explanations that were not provided during the original assessment. Many best judgment assessments are significantly reduced or set aside at this stage.
What happens if I cannot pay the demand raised in a Section 144 order? Apply for a stay of demand simultaneously with filing your CIT(A) appeal. The standard condition for a stay is payment of 20% of the disputed demand. The AO has discretion to grant the stay, and in practice, it is often granted for genuine cases where an appeal has been filed.
Is there a time limit for the AO to pass a Section 144 order? Yes. The order must be passed within 12 months from the end of the relevant assessment year. For AY 2025-26, this deadline is 31 March 2027. An order passed after this limit is time-barred.
Real Questions People Ask When They Face a Section 144 Order
"I never received any notice. The first thing I got was the Section 144 order itself. Is it valid?" If no prior notice was issued under Section 142(1) or 143(2), and no show-cause notice was given before passing the order, the assessment is procedurally invalid. This is a strong ground of appeal. Check your registered email and portal account carefully, then consult a CA or tax lawyer immediately. A writ petition to the High Court may also be appropriate if natural justice was clearly violated.
"The AO has assessed my income at three times what I actually earned. Can this really stand?" It can stand temporarily, but it is challengeable. At the CIT(A) stage, you can present your actual income with full documentation. Bring your bank statements, ITR computation, investment records, and everything you would have shown during the assessment. The appellate authority is not bound by the AO's estimate and can revise it downward based on evidence.
"I missed the 30-day appeal deadline because I didn't know about the order. What now?" File a condonation of delay application along with your Form 35 appeal. Explain clearly why the delay occurred and why the cause was genuine. CIT(A) has discretion to admit delayed appeals when the reason is convincing. Do not wait further.
"Do I need a CA to fight a Section 144 order, or can I handle the appeal myself?" Technically, you can represent yourself, but a best judgment assessment appeal is not simple. The AO made assumptions about your income based on data you never responded to. Dismantling those assumptions requires structured legal arguments, not just document submission. A CA or tax advocate familiar with appellate proceedings is strongly recommended here.
"I got a Section 144 order for a year where I had no income at all. This seems completely wrong." This is more common than people expect, particularly when AIS data shows transactions (bank credits, property registrations, investments) that the department interprets as income. File your appeal with a clear statement of your income position for that year, supported by bank statements, investment account summaries, and any relevant salary or business records. Zero-income claims are entirely legitimate and can be established with the right documentation.
