What is Intimation under Section 143(1) and when it is issued?

If an assessee having taxable income must file an Income Tax Return (ITR) each financial year. After filing the ITR, the income tax department would process the return & check for any errors, omission or mistake in filing ITR. If the errors, omission or mistake in an income tax notice are minor, a summary assessment called Intimation under Section 143(1) can be completed without calling the assessee.

Hence, intimation u/s 143(1) is the most common type of tax notices received from the Income Tax department. On receiving any intimation u/s 143(1), the taxpayer without panicking can take steps to understand the intimation received & further comply with the request received, if any.
