Does the tax audit deadline also get postponed along with the ITR filing deadline?

No, the tax audit deadline is usually different. The September 16 extension is only for non-audit cases. For people or businesses that need an audit, their deadline is 30th September or 31st October, depending on the rules for that year. The government has not mentioned an audit extension in this notification.

The audit deadline was not extended to September 16. That date is strictly for those who did not require audit. Normally, tax audit reports under Section 44AB are due by the end of September, and in some cases, the government may extend that too, but it will be a separate notification.
