I've had 2 incorrect notices today. One for a long-established company with a February year end. Last CTR submitted for 28/02/22. Today's notice asks for 28/02/23 to 28/02/23 (ie 1 day). I'm just about to submit year end 28/02/23.
2nd is for a company formed in October 2021. Already submitted 2 CTRs up to 31/10/2022. Today's notice requests the period 01/12/2022 to 31/10/23.
If I ignore the notices will the dates will sort themselves out once returns are submitted or do I waste more admin time trying to contact HMRC to explain?
