There are situations where one company is VAT registered and other related companies are either partially exempt or not registered for VAT, so in these circumstances not charging VAT is an advantage.
The following are not Taxable supplies for VAT:
Common Directors – Notice 700/34 (May 2012)
An individual may act as a director of a number of companies. For convenience one company may pay all the director’s fees and then recover appropriate proportions from the others.
The individual’s services, such as attending meetings or approving expenditure, are supplied by the individual to the companies of which they are a director. The services are supplied directly to the relevant businesses by the individual and not from one company to another. Therefore there is no supply between the companies and so no VAT is due on the share of money recovered from each company.
Joint Employment – Notice 700/34 (May 2012)
Where staff are jointly employed there is no supply for VAT purposes between the joint employers. Staff are jointly employed if their contracts of employment or letters of appointment make it clear that they have more than one employer. The contract must expressly specify who the employers are for example ‘Company A, Company B and Company C’, or ‘Company A and its subsidiaries’.
Paying a Bill on behalf of an associated business
This is basically an inter company loan which will be repayable in full, its not a taxable supply.
If insurance is being recharged and both businesses names are on the policy it can be treated as a disbursement of an exempt insurance so that its not vatable.
