Ontario corporate tax calculator

Our financial calculators start with default values to suggest what to enter typically in each modifiable field, displayed as blue text boxes, in order to simulate a common scenario.

Please change those values with your own. To keep track of your changes, the blue box will turn gray after they are modified.

You will also notice that our calculators behave like financial applications and recalculate automatically all values with each change instead of having to click on some extra button or going to a new result page, this is intentional and helps understand the effect of one change with the overall result in a more dynamic and instantaneous manner.

However, charts in our older calculators are not updated automatically, so if there is an "Update" button next to the chart, make sure to click on it after you make a change before you analyze it.
