Received a letter from past due credit

Number 01414790053 saying my Ltd company owes £200 - is this legit? Also number on letter 07860057534 I see nothing to pay on business tax account, same for personal taxes.

Hi Allen88,
Please refer to guidance at: Identify tax scam phone calls, emails and text messages EnglishCymraeg,
and guidance at: Report suspicious HMRC emails, text messages and phone calls.  
HMRC do not publish mobile telephone numbers on letters, and are aware of automated phone call scams.  
Thank you.
