Group VAT liability

SUGGESTED

Hi, I’m hoping someone may know the answer to this. 

the company I work for recently went Group VAT registered (x3 companies) 

I was told to raise the VAT returns in x2 of the companies & make the adjustment on the ‘holding’ company and send off just one return. 

However, since doing this there is now a liability sat on the VAT accounts.

if I post the payments/receipts between the companies will this rectify the issue? Or is there a journal entry I should be doing? 

Thanks
