The diesel fuel rebate scheme which returns most of the excise on diesel fu
el used off-road by agricultural and mineral producers has been debated. Re
moval could cause three inefficiencies (input choice distortion, deadweight
losses on reduced exports, and flow-on inefficiencies in domestic processi
ng) and two efficiencies (from reducing other tares and savings an administ
rative and compliance costs). Empirical studies suggest high net efficiency
costs from removal, but while business input taxes have no place in an eff
icient taxation structure, a small reduction in the rebate could yield some
revenue at a low marginal deadweight loss.
