Section 40A(2)(b) Related Party Transactions: Guide

June 4, 202612 Min ReadFaheem Ferdous

Corporate tax compliance requires careful monitoring of transactions with specified related parties. Under Section 40A(2)(b) of the Income Tax Act, 1961, tax officers can disallow expenditures if the payments are excessive or unreasonable compared to fair market value.

Establishing a structured **related-party transaction audit protocol** is essential to prevent tax adjustments and comply with Form 3CD filing rules.


The Income Tax Act defines specified related parties under Section 40A(2)(b):

Taxpayer TypeSpecified Related PartiesSubstantial Interest Threshold
IndividualRelatives (Spouse, brother, sister, ancestors, lineal descendants)N/A
Company / HUF / FirmDirectors, partners, members, or their relativesN/A
Any EntityAny individual or entity holding substantial interest in the business20% or more voting power or share in profits

2. Case Study: Disallowing Excessive Rent Paid to a Director's Relative

A company leases office space from the spouse of its managing director. The lease agreement details:

  • Actual Rent Paid: ₹2,50,000 per month (total ₹30,00,000 per year).
  • Fair Market Value (FMV): Independent valuations for similar properties in the area indicate a market rate of ₹1,50,000 per month (total ₹18,00,000 per year).
  • Disallowance: The tax auditor flags the ₹12,00,000 difference (Actual ₹30L - FMV ₹18L) as excessive under Section 40A(2)(b). The disallowed ₹12,00,000 is added back to taxable income in the tax return, and the details are reported under Clause 23 of Form 3CD.

3. Clause 23 Form 3CD Reporting Requirements

Under Clause 23 of Form 3CD, tax auditors must report:

  • The name and PAN of the specified related party u/s Section 40A(2)(b).
  • The relationship definition.
  • The nature of the transaction (such as purchase, rent, or salary).
  • The transaction value and the disallowed excessive portion.
