dirtydog said:Why should fuel duty be subject to inflationary tax increases?
We don't increase VAT or other taxes each year with inflation; the rate stays the same.
Isnt it obvious?
VAT is expressed as a %age of the purchase price - as prices rices, so does the tax take - its inherently index linked.
Fuel duty is expressed in pennies per litre - if the cost of fuel doubles the effective tax rate halves. Thats why the duty has to be adjusted to changing prices.
