The estimated increases in the standard rate of VAT make use of current assumptions about the effect that price increases may have on purchasing patterns and the consequential impact on tax revenue. However, the changes proposed are sufficiently great, especially at the higher levels, for the figures to be subject to substantial errors of estimation. For this reason they have been rounded. Given these roundings, the effects of increasing the thresholds by more than £6,000 do not greatly differ from the effects of £6,000 increases.
