Annual compliance for a Private Limited Company is not optional — it is mandatory under the Companies Act 2013. Missing deadlines attracts heavy penalties that compound over time. A company that fails to file annual returns for 3+ years can be struck off by MCA and its directors can be disqualified for 5 years.
The compliance calendar has two main components: MCA/ROC filings and Income Tax filings. Both must be completed on time, every year.
