Late fine for filing ITR

A partner in a firm subject to tax audit usually has until October 31st to file their Income Tax Return (ITR). However, one user encountered a £1,000 late filing penalty when submitting an ITR-3 for AY 2022-23, even though the firm's ITR and tax audit report were filed on October 23rd. The discussion seeks advice on how to resolve this discrepancy and ensure the partner's return is not considered late.
