How does Tax work?

TaxiCaller treats trip fares as tax-inclusive.

When you set a tax rate in your tariff, you’re telling the system how much tax is already included in the fare.

The total fare stays the same. Tax is not added on top.

How the calculation works

If the total fare is 100.00 and the tax rate is 13%, the system divides 100.00 by 1.13 to work out the fare before tax.

Fare Breakdown Amount
Fare before tax 88.50
Included tax 11.50
Total fare 100.00

If you want a $100.00 fare before tax at 13%, set the fare to $113.00 and the tax rate to 13%. TaxiCaller will then calculate $100.00 before tax and $13.00 in included tax.

How tax appears on invoices

Invoices use the tax already calculated on the trip receipt. TaxiCaller does not currently support adding sales tax on top of trip fares when generating an invoice.

If you use legacy invoicing, turning off Tax included adds tax to the total shown in the invoice list. The customer’s PDF leaves out that tax, so the totals differ. Keep Tax included enabled if you want the PDF to show the tax included in the invoice total.

What about extras?

Extras have their own tax calculation. When a tax rate applies to an extra, TaxiCaller adds the tax on top of the extra’s configured price.
