A tax rate is a named percentage your company charges on sales or pays on purchases — for example GST 5% or PST 7%. A tax group combines two or more rates into one, so that a single choice on an item or an invoice line charges both — for example BC TAX = GST 5% + PST 7%, charging 12% in total.
The Taxes screen is where you create, change and remove them. Every item has a tax, invoices and bills work tax out from it, and the sales tax return totals it.
Opening the Taxes screen
- Lists ▸ Sales Tax Code List
- Menu ▸ Admin ▸ Taxes (in the Catalog section)
Your role needs the Taxes permission (on the Workspace tab of the role). Without it, a Manager Approval box asks an Admin or Manager to approve opening the screen this once. To save changes, anyone who is not an Admin or Manager also needs the matching Tax Rates permissions (create, update, delete) on the role's Web Access tab; otherwise the save is refused with Unauthorized action.
The Taxes screen
The heading reads Taxes, with Tax rates applied to products underneath.
| Part | What it does |
|---|---|
| Refresh (top right) | Re-reads the list from this computer's copy of your company. |
| Tick a tax to apply it to every new product by default. | Explains the Default column. |
| Tax list | Every rate and group, in alphabetical order. |
| Add Tax (bottom right) | Opens the Add Tax form. |
Each row shows:
| Item | Meaning |
|---|---|
| Icon | A percent sign for a single rate; a stack of layers for a tax group. |
| Name | The tax's name. |
| Second line | The percentage, followed by Tax group for a group. A group's percentage is the total of its members. |
| Edit (pencil) | Opens the rate or group for editing. |
| Delete (red bin) | Deletes it after you confirm. |
| Default (tick box) | The tax that new products start with. Only one can be ticked; untick it to have no default. |
When the company has no taxes yet, the screen reads No tax rates yet. Tap 'Add Tax' to create one (e.g. VAT@10%).
Adding a tax rate
- Click Add Tax.
- Type the Tax name — for example
GST 5%orPST 7%. Using the percentage in the name makes lists easier to read. - Leave Tax group (combine rates) off.
- Type the Rate (%) — for example
5. Decimals are allowed (9.975). Use0for a zero-rated or exempt code. - Click Add.
A green message confirms Tax rate added successfully.
Adding a tax group
You need at least two single rates first.
- Click Add Tax.
- Type the Tax name of the group — for example
BC TAX. - Switch on Tax group (combine rates) (e.g. BC TAX = GST 5% + PST 7%). The switch is greyed out until at least two single rates exist.
- Under Combine these rates:, tick each rate the group charges. Each is shown with its percentage, for example GST 5% (5%).
- Check the Combined rate line underneath (for example Combined rate: 12.00%).
- Click Add.
A green message confirms Tax group added successfully. A group can only contain single rates — not other groups.
The Add Tax form
| Field | What it means |
|---|---|
| Tax name * | What the tax is called on items, invoices, bills and reports. |
| Tax group (combine rates) | Shown only when adding. On: build a group from existing rates. Off: a single rate. |
| Rate (%) * | Single rates only. The percentage, zero or more. |
| Combine these rates: | Groups only. Tick two or more single rates. |
| Combined rate | Groups only. The total of the ticked rates, worked out for you. |
Editing a rate or group
Click the pencil on the row.
- A single rate opens as Edit Tax Rate: change the Tax name or Rate (%) and click Save (Tax rate updated successfully). Every group that contains the rate has its total recalculated automatically.
- A group opens as Edit Tax Group: SeroBooks first reads the group's current members, then shows the name and the ticked rates. Change them and click Save (Tax group updated successfully). You cannot turn a group into a single rate, or a rate into a group.
Deleting a rate or group
- Click the red bin on the row.
- Confirm Delete in the Delete tax rate '…'? box (This action cannot be undone.).
SeroBooks refuses the delete when the tax is still in use:
| Message | What to do |
|---|---|
| Cannot delete: tax rate is part of a tax group | Edit or delete the group that contains it first. |
| Cannot delete: N product(s) still use this tax rate | Change those items to another tax first. |
If the deleted tax was the Default, the default is cleared.
The default tax for new products
Tick the Default box on a row to have new items start with that tax: new products added from Admin ▸ Products, and new services on the Services list. The choice belongs to the company, so every computer and every user starts new items with the same tax; changing it needs the right to change the company preferences (an administrator), otherwise the tick is refused with the reason. It applies to new items only — items you already have keep their tax.
If no default is ticked, a new product starts with the first tax in the list and a new service with a 0% rate.
Telling the books which tax each rate is
For your GST/HST and PST/QST returns to come out right, each rate must be linked to the right tax account. This is set in Company ▸ Accounting Setup, in the card Which tax each rate is:
- Point a rate at the Federal — GST/HST account to make it count towards the GST/HST return.
- Point a rate at the Provincial — PST/RST/QST account to make it count towards the provincial return.
- A rate left unmapped is Guessed from name, and a rate called something like "G" or "S" counts towards nothing — the return comes out short while looking normal. An amber note reads N rate(s) are still being guessed from their name. Map them to one of the two tax accounts above.
- A 0% rate shows Zero-rated.
See Accounting Setup (posting accounts) and How sales tax works in SeroBooks.
In a United States company the two accounts are called State — sales tax and Local — county and city.
Examples for Canadian provinces
| Where you sell | Typical set-up |
|---|---|
| Alberta, and the territories | One rate: GST 5%. |
| Ontario | One rate: HST 13%. |
| New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island | One HST rate at the province's HST percentage. |
| British Columbia | GST 5%, PST 7% and a group BC TAX = both. |
| Saskatchewan | GST 5%, PST 6% and a group of both. |
| Manitoba | GST 5%, RST 7% and a group of both. |
| Quebec | GST 5%, QST 9.975% and a group of both. |
Check the current rates with the tax authority before you set them up; the percentages above are examples.
Tips
- Name rates with their percentage —
PST 7%is clearer on an invoice line thanPST. - Create an exempt or zero-rated code (
Exempt 0%) for items and customers that are not taxed. - Map every rate in Accounting Setup straight after creating it.
Common problems
The Tax group switch is greyed out. You need at least two single rates before you can combine them.
"Select at least 2 rates to combine". Tick at least two rates in the group.
"Enter a valid tax rate". The Rate (%) box is empty, not a number, or negative.
A tax shows in the list on this computer but not another. The other computer has not refreshed yet. Use Menu ▸ Sync DataBase there.
The sales tax return is short. A rate is not mapped in Accounting Setup ▸ Which tax each rate is. Map it to the federal or provincial account.
