Do You Have to File a Tax Return for a Dormant Company?
No, you do not necessarily need to file a tax return for a Dormant Company. However you may have received a Notice to Deliver a Company Tax Return for a Limited Company since HMRCs default position is to expect a Corporation Tax Return for every Limited Company unless they have received notification otherwise.
If you have received a Notice to Deliver a Company Tax Return from HMRC it may not be too late to advise them of Dormant Company Status and avoid filing a Tax Return. You may still be able to Advise HMRC of Dormant Company Status Yourself.
