Skip the Appeal, Avoid the Penalty? Section 270AA and 440 Waiver Explained
An assessment order lands with a large addition, and a penalty notice for under-reporting or misreporting comes with it. The penalty can be 50% or even 200% of the tax on that income, and prosecution is possible on top.
Before you file an appeal by reflex, there is one window that closes fast: the immunity route under section 270AA of the 1961 Act, now section 440 of the Income-tax Act, 2025.
Quick answer: If you pay the assessed tax and interest within the demand notice period, file no appeal, and apply within one month from the end of the month in which you receive the order, the AO must grant immunity from penalty and prosecution. Under the 1961 Act this was barred for misreporting cases. Under section 440 as amended by the Finance Act, 2026, misreporting cases can also get a waiver by paying additional income-tax of 100% (or 120% in one category). The application is now Form 161.

The Income-tax Act, 2025 applies from 1 April 2026. This post gives the 1961 section first and the 2025 Act section in brackets. For the wider mapping of appeal provisions, see income-tax appeals under the 2025 Act vs the 1961 Act.
What does section 270AA immunity give you?
Section 270A (section 439) levies penalty on under-reported income. The rate is 50% of the tax payable on that income, rising to 200% where the under-reporting is in consequence of misreporting.
Section 270AA (section 440) is a settlement-style exit. You accept the assessment, pay, and give up the appeal. In return the AO grants immunity from penalty under section 270A (section 439) and from prosecution under sections 276C and 276CC (sections 478 and 479).
The Delhi High Court has described its purpose as encouraging taxpayers to fast-track settlement, help recovery of the demand and reduce protracted litigation.

Who qualifies under the 1961 Act?
Under section 270AA of the 1961 Act, the conditions are:
Pay in full: the tax and interest payable under the order of assessment or reassessment under section 143(3) or 147 is paid within the period in the notice of demand.
No appeal: no appeal is filed against that order.
Apply in time: the application in Form 68 (Rule 129) is made within one month from the end of the month in which the order is received.
Not a misreporting case: immunity is not available where penalty proceedings were initiated for misreporting under section 270A(9).
The AO grants immunity only after the period for filing an appeal has expired. Section 270AA(4) requires an order accepting or rejecting the application within one month from the end of the month in which it is received, and a rejection needs a hearing first.
What changed in section 440 of the 2025 Act?
The Finance Act, 2026 substituted sub-sections (1) to (4) of section 440 and renamed it "Waiver of penalty and immunity from prosecution". The key shift is that it now speaks of waiving a penalty already levied under section 439.
Plain under-reporting: pay the tax and interest under the assessment order (section 270(10)) or reassessment order (section 279) within the demand period, and file no appeal.
Misreporting under section 439(11)(a) to (f): also pay additional income-tax equal to 100% of the tax on the under-reported income, in lieu of the penalty.
Misreporting under section 439(11)(g): this clause, inserted by the Finance Act, 2026, covers income referred to in section 195(1)(b). The additional income-tax here is 120%.
No prosecution started: no waiver is granted if any proceeding under Chapter XXII (offences and prosecutions) has been initiated.
Time limits: apply within one month from the end of the month in which the order is received. The AO decides within three months from the end of the month of receipt (section 440(5)), after the appeal period in section 358(3)(a) expires.
Once the application is accepted, no appeal under section 356 or 357 and no revision under section 378 lies against that order (section 440(8)). The AO's order under section 440(5) is final.
CBDT Notification No. 134/2026 dated 8 October 2026 (G.S.R. 871(E)) substituted Form 161 under Rule 231 of the Income-tax Rules, 2026. The new form asks you to split under-reported income into misreporting under clauses (a) to (f), clause (g), and not in consequence of misreporting, and to compute the additional tax at 100% and 120%.
Separately, the Finance Act, 2026 amended section 471 so that, for draft and final assessment or reassessment orders made on or after 1 April 2027, the section 439 penalty forms part of the assessment order itself. That makes the waiver decision part of reading the assessment order.
Worked example: waiver cost vs penalty
Kavya Traders LLP (illustrative) receives a 2025 Act assessment order on 18 August 2028. It adds ₹10,00,000 as unexplained expenditure and levies penalty under section 439. Assume tax on that income, at 30% plus 4% cess, is ₹3,12,000.
If treated as misreporting under clauses (a) to (f): the penalty at 200% is ₹6,24,000. The waiver route costs additional income-tax of 100%, that is ₹3,12,000, over and above the tax and interest.
If treated as plain under-reporting: the penalty at 50% is ₹1,56,000. The waiver route costs no additional tax, only full payment of the tax and interest.
Deadline: the order is received in August 2028, so Form 161 must be filed by 30 September 2028, and the demand must be paid within the notice period.
What is given up: any appeal against the addition. If the addition is weak on merits, an appeal may cost less overall, but penalty and prosecution risk then stay open.
Under the 1961 Act, the misreporting version of this case would get no immunity at all, so the only route would have been an appeal.
Waiver or appeal: how to decide
There is no universal answer. These points usually decide it:
Strength of the addition: if it rests on a clear legal error or ignored evidence, the appeal route keeps that argument alive.
Cost comparison: compare the penalty plus prosecution exposure with the extra tax payable for the waiver, if any.
Repeat issues: accepting an addition can make it harder to argue the same issue in later years.
Cash flow: the waiver needs full payment within the demand period, while an appeal can run with a stay on a 20% deposit. See stay of demand pending appeal.
Settlement alternatives: for older disputes, check whether a dispute resolution scheme is open, such as Vivad se Vishwas.
How to file Form 161 step by step
Read the order and penalty part: note the DIN, date of order, date of service and the limb of section 439 applied.
Work out the tax on under-reported income under section 439(12) and the additional tax at 100% or 120% where relevant.
Pay the full tax, interest and any additional tax within the demand notice period and keep the challan details (BSR code, serial number, date).
File Form 161 online on the e-filing portal; the CBDT FAQs say it cannot be filed offline, and a PAN is required.
Sign the verification that no appeal has been filed and none will be filed before the period in section 440(5) expires.
Track the status under e-File, Income Tax Forms, View Filed Forms, and attend the hearing if a rejection is proposed.
The CBDT FAQs confirm that a partly paid demand does not qualify, and that Form 161 cannot be filed after an appeal has been filed.
What courts have said
In Schneider Electric South East Asia (HQ) Pte Ltd v. ACIT (Delhi High Court, W.P.(C) 5111/2022, 28 March 2022; (2022) 443 ITR 186), immunity was denied because the assessment order used the word "misreporting".
The Court set aside the rejection. The penalty notice did not specify whether the limb was under-reporting or misreporting, nor how section 270A(9) was satisfied, so the denial was arbitrary. It directed the AO to grant immunity.
The lesson for 1961 Act cases is to check the penalty notice itself. For defences when penalty is contested, read penalty defence under sections 270A and 271(1)(c).
Common mistakes
Missing the one-month window because the clock was counted from the order date rather than the end of the month of receipt.
Paying part of the demand and expecting immunity.
Filing Form 35 first "to be safe", which closes the waiver route.
Ignoring the 100% or 120% additional tax in misreporting cases under the 2025 Act.
Not checking whether a prosecution proceeding has already been initiated.
