Install the tax calculators
WordPress 6.0 or newer and PHP 8.0 or newer. Lite is free. Pro is the paid add-on for payroll and the other tools.
Install Lite
- Download the free Lite zip. Lite is not on WordPress.org yet. A listing is coming.
- In WordPress, open Plugins, choose Add New, then Upload Plugin. Choose the Lite zip and activate it.
Activate Pro
Install the Pro zip the same way, then open your account page and copy the licence key into Pro settings. Updates and support continue while that licence is active.
Add a calculator
Use the BOMCAS Calculator block, or paste a shortcode. Two examples:
[bomcas_calculator id="income-tax" province="ON"]
[bomcas_calculator id="sales-tax" province="BC"]
Settings and a new tax year
Colours, the lead form, and which tools are offered are in the Calculators menu. When a new year is published, replace the rate file. The next page view uses the new numbers. You do not edit each page.
If a page is blank
Confirm Lite is active, the shortcode names a real calculator id, and the province code is one the rate file contains. What a visitor types stays in the browser.
