Hi Diego,
In order to treat incurred VAT as input tax then the invoices would need to be in the name of the business.
However if the VAT was incurred prior to the business being incorporated please see the guidance below:
If your business is a corporate body (a company, charity or association), the rules do not allow you to reclaim any VAT on goods or services obtained before the body was incorporated.
But you can treat this VAT as input tax if the:
rules in paragraphs 11.2 or 11.3 would allow you to do so if the goods or services had been supplied to the person who is now registered for VAT
Goods or services were obtained or imported by a person who became a member, officer or employee of the body
Person was reimbursed for the full cost
Person was not a taxable person at the time of the supply or importation
VAT guide (VAT Notice 700) 11. Input tax when VAT paid on goods and services received before VAT registration
Thank you.
