sales-tax-cad

🧾 Canadian sales tax calculator

This package exports a single class. It's rather small and only does one thing: calculate CAD taxes. For those who just care about the total, you can call sum, as shown below, or you can get a tax trace using get.

Note that the constructor takes three arguments:

1. The two-letter province code;
2. The taxable number value;
3. The number of decimal points to include in output.

  const SalesTax = require('sales-tax-cad');
  
  const tax = new SalesTax(
    'ON', // reference rates.json if unsure
    21.41, // ensure that this is a number
    2, // leave blank for raw result
  );
 
  tax.get(); // returns an array of all chargeable taxes
  tax.sum(); // returns the total payable tax

Method	Description
get	Returns an array of applicable taxes
get	Returns the total payable tax (reduces get results)
