Corporation Tax on Dormant Company

I’ve owned two community interest companies for a few years (3-5 years each). Neither has been actively trading since their creation, by HMRC’s guidelines. I’ve never filed corporation tax returns as my understanding was I didn’t need to. Going through my admin for Companies House registrations today, I saw that I should declare my companies as “Dormant for Corporation Tax”. I’ve just done this for both, indicating on the forms that neither was eligible for tax since creation. Do I owe any penalties for not declaring this till now/not doing corporate tax filings? Again my understanding was that this wasn’t needed giving neither company has actually been trading and neither has produced any profit whatsoever.

Hi,
HMRC does not seek to impose a specific penalty for late notification that a company has been dormant; however, if HMRC was not informed the company was dormant, penalties for failing to deliver tax returns might have been charged.
You can find more information about late-filing penalties and tax determinations at:
Company Tax Returns.
You can see details of any late-filing penalties on the companies’ online accounts.
If you cannot access HMRC’s online services, you can call us on 0300 200 3410 to request this information.
Thankyou.
