Relationship between ROC Filing and Income Tax Filing of a Private Limited Company

Dear Members,

If a private limited company has filed its Income Tax return for all the assessment years since its incorporation, but haven't complied with MCA filing i.e., haven't filed its AOC-4 & MGT-7A for any of the assessment years.

What should be done in this circumstance?

Should all ROC filings be done backdated? Or can it apply for Strike off in SKT-2?

Please guide.
