If income is nil for a trust and return is filled after the due date i.e. 31/07/2024 then section 234F fess penalty for ₹ 1,000 is applicable?

Yes, if the trust is required to file a return and files after 31/07/2024, a ₹1,000 late fee applies under Section 234F (if income is below ₹5 lakh). If filing is not mandatory, no penalty.
