Common questions
Does a percentage tax stay fixed in cents per litre?
No. VAT, GST and sales taxes vary with their taxable base. For a tax-inclusive price and one rate r, the tax amount is price × r / (1 + r).
Why are some tax records marked unverified?
A published summary can omit a local levy, a tax-base rule or an effective date. Unverified records are not treated as a complete statutory tax stack.
