nah Full lecture Not Required , went on a Vat course , Fell Asleep..Buffet was nice though.

and as for Intrastat declerations....

I am only showing from our business point of view that we are not able to charge or claim vat back on the postage we use , and was wondering if it was the same. as when we buy our postage (Franking Machine) we do not apparently get charged vat
Quote from vat N.700
1.4 Aren’t postal charges exempt from VAT?
Postal services provided by the Post Office are exempt from VAT, but this exemption does not extend to similar services provided by other suppliers, even where this might be seen as being in direct competition with the Post Office.
However, if any delivery charge you make to your own customers includes the cost of stamps you buy from the Post Office you may have to charge VAT on the whole amount including the cost of those stamps.Clear as Mud...
Anyone use (I think its called) The Balsa cabin ??
