August 2026 Compliance Calendar: Due Dates Income Tax, ITR, TDS, GST, MCA & Other

August 2026 is one of the most important compliance months for taxpayers, businesses, professionals, companies and deductors. Following the completion of the July filing season, August brings several crucial due dates under the Income-tax Act, GST law, MCA and labour laws.

Missing these due dates may result in late fees, interest, penalties, loss of tax benefits or delayed processing of returns.

This article provides a comprehensive compliance calendar for August 2026.


Income Tax Compliance

  • ITR-3 (eligible non-audit cases)
  • ITR-4 (Sugam)
  • Working partners covered under the prescribed category
