I recently got involved in a transaction where the searchers had certain "budget", and were considering the pros and cons of acquiring the assets vis-a-vis the stock. Here's some tax aspects you should take into account:

Stock:
- No VAT
- Tax liabilities 'stay' with the company

Assets:
- 16% VAT (subject to VAT exemptions), which might not be creditable by the acquiring SPV
- Tax liabilities might still follow the assets, but are easier to 'fence'
