Intimation under Section 143(1) is not a Notice but a communication received from the income tax department. Once the assessee files his income tax return, the income tax department does a preliminary assessment. This includes verifying arithmetical errors, any incorrect claim in the return, the difference in tax calculation, verification of tax payment, etc. This letter basically matches the calculations in the Income Tax Return filed with the calculations computed by the income tax department.
Intimation u/s 143(1)
The intimation is a communication that the income tax department sends to the taxpayer after processing the income tax return. It comprises the calculations as per the return filed by the taxpayer with the calculations as per the computation of the income tax department. If both the calculations match, the taxpayer need not worry and can wait for the refund if any. However, if there is a mismatch in the calculation, the taxpayer should take relevant action to resolve the same.

Time Limit for issue of Intimation u/s 143(1)
Effective 1st April 2021, there was a revision in the rules for the time limit to issue intimation under Section 143(1). The income tax department must issue intimation u/s 143(1) within 9 months from the end of the financial year in which the taxpayer files the return. Earlier, this time limit was within one year from the end of the financial year in which the taxpayer files the return.
Example
Taxpayer files ITR for FY 2020-21 in July 2021
End of financial year in which return is filed – 31st March 2022
Nine months from the end of the financial year – 31st December 2022
Therefore, the ITD can send intimation for ITR of FY 2020-21 up to 31st December 2022
If a taxpayer does not receive any intimation within such period, it means that there are no adjustments and changes to the ITR filed. There is no change in tax liability or refund. Thus, the Income Tax Return filed is deemed to be intimation u/s Section 143(1).

Hey @TanyaChopra
An Intimation u/s 143(1)(a) is issued when there’s a mismatch between your tax credit statement i.e. Form 26AS and your tax return. This happens through automated checks at CPC (Centralized Processing Center) in Bangalore where your returns are processed.
You can respond to this intimation by registering and logging in to your account on the Income-tax website. You need to determine how you’re going to be responding to the intimation - there are three options available.
As you might imagine, there’s no real need to panic here as the intimation can be easily taken care of.
Hope this helped! If you have any further questions, feel free to ask.
@Sakshi_Shah1 could you help with this ?
If you agree with the tax notice issued, there is an option to pay the outstanding demand under the option of e-proceedings. You can pay the tax from that option since the option for filing a Revised Return is not available after 31st march 2022.

@Sakshi_Shah1 can you help ?
Hey @Sahil_1186
If you have filed the original ITR u/s 139(1) before the due date, there is nothing to worry. You can carry forward the loss even if the ITR was revised. This looks like an error from the end of income tax department. They have sent system-generated notices to many taxpayers with the same query. You should submit a response to the tax notice from your account on the income tax website requesting them to re-process the ITR and allowing carry forward of loss since the original ITR u/s 139(1) was filed within the due date.
When is the notice u/s 143(1)(a)(iii) issued?
Hi @Nandana
When the return is filed after the due date u/s 139(1) and yet the loss has been claimed, notice u/s 143(1)(a)(iii) is issued to disallow such loss.
Hope this helps!
Got following Notice for AY 2021-22
“Disallowance of loss claimed, as the ITR of the previous year for which set off loss is claimed was furnished beyond the due date specified under sub-section(1) of section 139 - 143(1)(a)(iii)”
A.Y. 2020-21 Filed on :Sep 25, 2020 (loss reported)
A.Y. 2021-22 Filed on : Nov 23, 2021 (loss adjusted)
I remember date was extended for both AY.
Please help
