Demand Notice (Section 156)
A demand notice under Section 156 is issued by the Assessing Officer to a taxpayer when any tax, interest, penalty, fine, or other sum is determined as payable following an assessment, requiring payment within 30 days of service of the notice.
Section 156 is the statutory vehicle through which the Income Tax Department communicates a confirmed tax demand to the assessee after completing an assessment — whether a summary assessment under Section 143(1), regular assessment under Section 143(3), best judgment assessment under Section 144, or reassessment under Section 148. The notice specifies the amount payable and the due date, which is ordinarily 30 days from the date of service.
Upon receiving a demand notice, a taxpayer has several response options depending on the nature and validity of the demand. If the demand results from a CPC processing error — for instance, non-credit of TDS or incorrect computation of tax — the assessee should first file a rectification application under Section 154 while simultaneously applying for a stay of demand. If the demand is the result of an assessment order with which the assessee disagrees, the first recourse is an appeal before the Commissioner of Income Tax (Appeals) under Section 246A within 30 days of the assessment order.
Filing an appeal does not automatically stay the demand — the assessee must separately apply to the AO for a stay of recovery, and under administrative guidelines, the AO may grant a stay if the assessee pays 20% of the disputed demand as a condition. This 20% demand payment requirement (introduced through CBDT instructions) has been a source of significant hardship for taxpayers facing large disputed demands and has been challenged in several High Courts, with mixed outcomes.
Interest under Section 220(2) accrues on unpaid demand at the rate of 1% per month after the 30-day payment window expires, compounding the financial burden for assessees in prolonged disputes. The department can initiate recovery proceedings under Section 222 (attachment of property), Section 226 (recovery by distress), and Section 281 (voiding certain transfers made to frustrate recovery) if demand remains unpaid.
For taxpayers who receive outstanding demand notices visible on the e-filing portal against their PAN, it is essential to reconcile whether the demand is correctly computed or is a CPC error. Many outstanding demands arise from TDS credit mismatches in older assessment years that pre-date the AIS era — these can often be resolved through an online response on the portal under the 'Pending Actions > Response to Outstanding Demand' section.
