Still liable for corporation tax after sold the company?

Need some advice

sold a company 2 yrs ago and recently was given a call out of the blue by HM Rev + Cust chasing an unfiled corporation tax

this falls within the period we had the company but they have been chasing the new owners for 2yrs and a large sum of penalties have accrued

really i feel this should have been done and dusted by accountants and lawyers at the time of transfer but for whatever reason this is the situation

as the shares and ownership of the company has transferred are we still liable for this tax? or is it the companies liability? which is now the problem of the new owners?

Would the company not owe the money , not the owners ?

thats what im hoping
the lady from HM rev + customs seemed to think otherwise (although dont think she would care where the money was coming from)

was hoping theres someone out here that knows for sure

Are you in the UK? If so, you might get more definitive answers on a UK site.

It probably depends on the terms & conditions of the company sale contract.
