Tax in Default and Penalty under Section 412

Updated 11 October 2026

An assessee is in default when a demand under a notice is not paid within 30 days, or within the extended time. Section 412 then lets the Assessing Officer levy a penalty, capped at the tax in arrears, after hearing the assessee. Good and sufficient reasons are a defence.

Understand Tax in Default and Penalty

Tax in default is about demand notices. When the department raises a demand under a notice of demand, you must pay it within the time allowed. If you do not, the law treats you as being in default.

Section 411 sets the rules for this. The amount in the notice is payable within thirty days of service of the notice. A shorter period can be set only if the Assessing Officer believes a full 30 days would harm revenue, and only with the previous approval of the Joint Commissioner. If you miss the due date, or the extended date, you are deemed to be in default (section 411(10)).

Default has two money consequences. First, interest under section 411(3): simple interest at 1% for every month or part of a month, from the day after the 30-day period ends until payment. Second, penalty under section 412. Interest compensates for delay. Penalty is a punishment on top of it. Section 412(1) says penalty is payable in addition to the arrears and the interest.

The penalty amount is what the Assessing Officer directs. In a continuing default, he can direct further amounts from time to time. But the total penalty cannot exceed the tax in arrears. Penalty cannot be levied without a reasonable opportunity of being heard, or where you prove the default was for good and sufficient reasons.

The law also gives relief. You can apply for more time or instalments before the due date. If you appeal, the Assessing Officer may treat you as not in default for the disputed amount. Paying the tax late does not wipe out the penalty, but if the tax demand is wholly cancelled by a final order, the penalty is cancelled and refunded.

Key rules to remember

Time to pay a demand: 30 days from service of notice (section 411(1)(a)); A shorter period is possible only with the Joint Commissioner's previous approval and where the AO believes 30 days would be detrimental to revenue.
Deemed default: Amount not paid within 30 days (or extended time) ⇒ assessee deemed in default (section 411(10)); Instalment default makes the whole outstanding amount in default, and later instalments are treated as due on the same date (section 411(11)).
Interest on default: Interest = 1% × unpaid demand × number of months or part months; Simple interest. Runs from the day after the 30-day period to the date of payment (section 411(3)).
Penalty under section 412: Penalty = amount directed by AO (plus further amounts in continuing default); total ≤ tax in arrears; Payable in addition to arrears and interest.
Conditions for levying penalty: Penalty can be levied only if a reasonable opportunity of being heard was given AND the assessee has not proved to the AO's satisfaction that the default was for good and sufficient reasons; Section 412(3). No penalty is levied where the assessee proves to the AO's satisfaction that the default was for good and sufficient reasons. Paying the tax later does not remove liability to penalty (section 412(4)).
Cancellation of penalty: Tax wholly reduced by final order ⇒ penalty cancelled and refunded; Section 412(5). Partial reduction does not cancel the penalty automatically.

How to solve Tax in Default and Penalty questions

Use this order for any question on default and penalty. It matches the ICSI answer style: provision, analysis, conclusion.

1Identify the demand: confirm a notice of demand was served and note the amount and the date of service.
2Compute the due date: 30 days from service, or the shorter period specified with Joint Commissioner's approval, or the extended date if the AO granted time or instalments before the due date.
3Check for relief: look for an appeal where the AO has treated the assessee as not in default, or foreign income that cannot be remitted to India.
4State the default: if payment is missed, say the assessee is deemed in default under section 411(10).
5Compute interest if asked: 1% per month or part of a month from the day after the due date to the day of payment.
6Apply section 412: penalty is as the AO directs, capped at tax in arrears, only after a hearing and if there is no good and sufficient reason.
7Conclude clearly: state whether penalty can be levied, the maximum possible, and note that late payment of tax does not remove it.

Quickest way: Four-question check

When to use it: Use it for short-note or case-based questions when time is tight.

Was the demand paid within 30 days (or extended time)? If not, default.
Is there any shield: appeal with AO's order, instalment arrangement honoured, or blocked foreign income?
Was a hearing given and is there a good and sufficient reason? If hearing missing or reason proved, no penalty.
Cap: penalty can never exceed the tax in arrears; interest is extra at 1% per month or part.

Common mistakes in Tax in Default and Penalty

Treating interest and penalty as the same thing.
Both arise from the same default, so they look alike.
Fix: Remember interest is a fixed 1% per month or part under section 411(3). Penalty is discretionary under section 412 and is in addition to interest.
Saying penalty is automatic once the assessee is in default.
Students stop at section 411 and forget the protections in section 412(3).
Fix: Always mention the need for a reasonable hearing and the good and sufficient reasons defence.
Believing that paying the tax before penalty is levied avoids penalty.
It seems fair that clearing the arrears ends the matter.
Fix: Quote section 412(4): payment before levy does not end liability to penalty.
Counting interest by exact days.
Students use the interest method of other tax provisions or daily logic.
Fix: Count whole months. Any part of a month counts as a full month.
Capping penalty at the interest or at the demand including interest.
The cap is misremembered.
Fix: The cap is the amount of tax in arrears, not interest and not total dues.
Ignoring instalment default consequences.
Students assume only the missed instalment is in default.
Fix: Under section 411(11) the whole outstanding amount is in default, and other instalments are treated as due on the same date.

Worked examples

Example 1

A notice of demand for ₹4,00,000 was served on Mr. Rao. The 30-day period under section 411(1) ended and he did not pay. He paid the full amount 2 months and 10 days after that 30-day period ended. Compute the interest under section 411(3), the maximum penalty under section 412 and comment.

Show the solution

Demand = ₹4,00,000. Due date = 30 days from service of the notice. Interest runs from the day after that period ends.
Delay = 2 months and 10 days. Two full months plus a part of a month. Part of a month counts as a full month, so months counted = 3.
Interest = 1% × ₹4,00,000 × 3 = ₹12,000.
Penalty: the AO may direct an amount after giving a hearing. It is discretionary, and the total cannot exceed the tax in arrears for this default, which is ₹4,00,000. This is a ceiling, not the amount that will be levied.
Penalty is in addition to interest. Paying the tax later does not remove liability to penalty (section 412(4)), but no penalty can be levied if Mr. Rao proves good and sufficient reasons.

Answer: Months counted = 3, so interest is ₹12,000. Penalty is discretionary; the most that can be levied is ₹4,00,000 (the tax in arrears for this default), and only after a reasonable hearing and if Mr. Rao fails to show good and sufficient reasons. The actual penalty is whatever the AO directs within that ceiling.

Example 2

Priya Textiles Ltd. was served a notice of demand. It applied to the Assessing Officer before the due date for payment in instalments, and the AO allowed three equal instalments. The company paid the first, but defaulted on the second. State the position under the Income-tax Act, 2025.

Show the solution

Section 411(5) allows the AO to extend time or allow instalments on an application made before the due date, on such conditions as he thinks fit.
Under section 411(11), default in any one instalment within the fixed time makes the assessee deemed in default as to the whole amount then outstanding.
So the second and third instalments both fall in default, and they are deemed due on the same date as the instalment actually in default (the missed second instalment date).
Interest under section 411(3) is simple interest at 1% for every month or part of a month. It runs from the day following the end of the period in section 411(1) (as extended where applicable) until the day the amount is paid. It does not start from the instalment default date.
Section 412 can then apply: penalty is as the AO directs, capped at the tax in arrears, subject to a hearing and the good and sufficient reasons defence.

Answer: Priya Textiles Ltd. is deemed in default for the whole outstanding amount, arising from the date of the missed second instalment. Interest under section 411(3) runs from the day after the end of the 30-day period under section 411(1) (as extended where applicable) until payment. Penalty under section 412 can be levied up to the tax in arrears after a reasonable hearing, unless the company proves good and sufficient reasons.

Exam tips

Cite section 411 for deemed default and interest, and section 412 for penalty. Examiners reward the correct pairing.
In case questions, check first whether the assessee applied for time or instalments before the due date or filed an appeal. These change the answer.
Write the cap in plain words: total penalty does not exceed the tax in arrears.
For interest, show months counted with part of a month as a full month, then the multiplication.
End every answer with a clear conclusion: default or no default, penalty possible or not.

Practice questions from Direct Tax at a Glance

Tax in Default and Penalty: frequently asked questions

When is an assessee deemed to be in default?

When the amount in a notice of demand is not paid within 30 days of service, or within the shorter or extended time allowed. This is in section 411(10). Missing an instalment also makes the whole outstanding amount in default.

What is the difference between interest and penalty for default?

Interest under section 411(3) is simple interest at 1% for every month or part of a month. Penalty under section 412 is an additional amount directed by the Assessing Officer. Penalty is discretionary and capped at the tax in arrears.

Can penalty be avoided if the tax is paid later?

Not by payment alone. Section 412(4) says the assessee is still liable to penalty even if the tax was paid before the penalty was levied. The defence is proving good and sufficient reasons for the default.

What is the maximum penalty under section 412?

The total penalty cannot exceed the amount of tax in arrears. It can include further amounts in a continuing default, but the combined total stays within that cap.

When is the penalty cancelled?

If a final order wholly reduces the tax for which the default penalty was levied, the penalty is cancelled and any amount paid is refunded. This is in section 412(5).
