AFAIAA = As far as I am aware -- I had forgotten about the 'New Build' zero rate & didn't know about the residential conversion issue - I don't have contacts in the building trade
Purchase Tax was eventually also charged on non luxury goods, I was involved because I ran a small printing business and you could hardly consider order books or business cards to be 'luxury'.
On the 25% for boats - I have never needed to enquire though I did at one time avidly read all the 'news' published by HMRC as far as VAT was concerned and don't recall a 'luxury' rate being introduced but I do know that the VAT status of yachts is something that needs scrutiny and good documentation. After all we really are talking 'luxury' items now.
I looked up the 25% vat rate. Initially Vat was set at 10%, Dennis Healey introduced two rates. Between 1974 and 1976 the rates were 8% and 25%.
“Higher rate introduced in November 1974 to apply to petrol (but not derv). In May 1975 this was extended to apply to a range of other consumer goods, for example domestic electrical appliances, radios, TVs and hi-fi equipment, furs and jewellery.“
I have remembered, it was the towing hitch (not ball) that I paid 25% vat on, it was for an ordinary small trailer but because I “could” use it on a boat trailer I was charged the higher rate. Shows the difficulty of two rates. I still have the trailer and hitch.
I found your comments on purchase tax interesting, it obviously needed simplifying. I can now see a problem with a simple sales tax. How to tell who is a final customer and who is trade and is going to charge their customer sales tax.
For example, I go in to say screwfix and buy some glue, screws and paint. I then go in to the builders merchant and buy some wood. I pay sales tax on both transactions.
A furniture maker goes in to the same shops and buys the same items. He or she should not pay sales tax. They then use the items to make some furniture which they then sell and charge the sales tax.
The problem is that screwfix and the builders merchants have to sometimes charge tax and sometimes not, depending on the customer. I can see that being very difficult and open to tax fraud. So maybe VAT is not as bad as I think, it is difficult to avoid.
