SCOPE & ROUNDING
What this sales-tax estimate covers
For tax-exclusive amounts, each applicable component is calculated independently and rounded half up to the nearest cent. For tax-inclusive amounts, the before-tax amount is derived from the combined rate, component amounts are allocated proportionally, and any one-cent remainder is assigned deterministically so every displayed amount reconciles.
This first release covers ordinary fully taxable purchases at the standard rate. Exempt and zero-rated supplies, product-specific rates, rebates, purchaser status, and place-of-supply rules can change the actual tax.
