Merging Subsidiary Companies

Hi All,

I'm looking for some input on the following situation, if possible:

Hold Co. owns 100% of the shares in company A + 100% of the shares in company B in a group structure. There is no property held in either company A or company B and the only potential chargeable gain is goodwill on which an exemption from CGT can be claimed. If company A takes over the assets and liabilities of company B in order to merge both companies after which point company B will be struck off the CRO register, are there any tax implications to be aware of? From looking at it, I don't think there is. Plant & Machinery can be transferred at TWDV. The only other assets are stock, debtors and cash.

Also, would there be any non tax implications i.e. company law, banking etc.?

Many thanks for any help or guidance,
Hcksaw.
