Saskatchewan - Provincial corporation tax

For a summary of the most recent changes, see What's new for corporations.

Lower rate

The lower rate of Saskatchewan income tax is 4.5% effective January 1, 2007.

The income eligible for the lower rate is determined using the Saskatchewan business limit of $500,000 effective July 1, 2008. Before this date the business limit was $450,000 effective July 1, 2007.

Higher rate

The higher rate of Saskatchewan income tax is 12% effective July 1, 2008. Before this date, the higher rate was 13% effective July 1, 2007.

This higher rate applies to all income not eligible for the lower rate.

If the tax year includes a date with a rate change, you have to prorate the tax calculation using the number of days before and after this date.
