Article 28 sets the general rate at 21% and then INCREASES it to 27% for metered gas, electricity and water - but only where the supply is outside premises used exclusively as a dwelling AND the customer is registered for the tax, so the same utility bill is 21% to a household and 27% to a registered business. The reduced band is stranger still: the statute never states 10,5%. It says those supplies take \"una alicuota equivalente al cincuenta por ciento (50%) de la establecida en el primer parrafo\" - half the general rate - so 10,5% is a consequence rather than a figure, and this page computes it that way. This page covers the rate schedule only."
