Rate Naming Standard
Use names a cashier and accountant can identify without opening the record. Include the legal label and percentage, for example GST 5%, VAT 20% or State Sales Tax 8.25%. Keep a deliberate 0% rate only when zero-rated items must remain visibly classified.
- Do not create duplicates such as GST5, GST 5 and Five Percent GST.
- Do not combine multiple legal components in one name when Tax Groups are required.
- Confirm decimal rates exactly; Value is a percentage, not a currency amount.
Create a Rate
- Open Manage -> Tax -> Tax Rates.
- Review the list to make sure the rate does not already exist.
- Click New.
- Enter the approved Name.
- Enter the percentage in Value, such as 5 or 8.25.
- Click Save.
- Confirm the new row displays the correct percentage.
- Assign it to a test item and run a one-unit test sale.
Edit or Delete a Rate
Use the edit icon for spelling corrections or an approved rate change. Before deleting, find items, quick-sale defaults and tax groups that use the rate. Prefer creating a newly effective rate and reassigning active items when the legal percentage changes; this preserves a clearer operational history.
- Never repurpose an old percentage name to mean a different tax.
- Check every branch when catalog data is shared.
- Do not delete a component still selected by a Tax Group.
- After a change, verify item details, cart tax, receipt tax and the relevant report.
Worked Check
For an exclusive 5% item priced at 100, the checkout total should be 105 before other discounts or charges. For an inclusive 5% item displayed at 105, tax is contained in that amount; the taxable base is 100 and tax is 5. Discounts can alter the taxable amount, so verify the final receipt rather than calculating from the original shelf price alone.
Troubleshooting
| Problem | Check |
|---|---|
| Rate is missing on the item form | Confirm Tax is enabled, the rate saved successfully and the item page was refreshed. |
| Tax value looks like money | The list uses the shop currency format, but Value is still the percentage entered in the rate. |
| Old items use the wrong rate | A default applies to new items; edit existing catalog records or use the supported bulk workflow. |
| Receipt total differs from expectation | Check inclusive/exclusive mode, quantity, discounts, charges and rounding on each line. |
