RSMike,
Your calculations have an error in how VRT is applied. I was not sure myself so I checked the SIMI website at
[broken link removed]
The critical line here is that
"Vehicle Registration Tax is applied ad valorem which means it is applied on a value which includes the tax itself"
So in your example above the VRT paid on a 116i is €7550 not €4992.
So you need to work backwards from the purchase price to arrive at the pre tax price as follows: (note VAT is not applied ad valorem)
Old VRT rate 25.00%
VAT rate 21.00%
Old purchase price €30,200.00
Deduct Old VRT €22,650.00
Deduct VAT €18,719.01
Pre Tax Price €18,719.01
Now apply VAT and the new VRT rate:
New VRT rate 20.00%
VAT rate 21.00%
Pre Tax Price €18,719.01
Add VAT €22,650.00
Add new VRT to arrive at new purchase price €28,312.50
