Why Worked Examples Matter
Worked examples show how reverse tax changes when the clean formula meets real receipts. Refunds, discounts, coupons, shipping, itemized receipts, invoices, and multiple items can all change the taxable base before the formula is applied.
Receipt examples
Show how to choose the correct tax-inclusive amount.
Refund examples
Show whether the refunded amount includes tax.
Discount examples
Show whether the discount changed the taxable base before or after tax.
Apply Examples Safely
- Choose the example that matches the transaction type.
- Compare the source total, rate, and taxable base.
- Apply the same workflow to your receipt only if the inputs match.
Example Misuse Patterns
- Copying an example rate into a different jurisdiction.
- Ignoring whether a discount was before tax or after tax.
- Using a single-item example for an itemized receipt.
