Investment income is taxed differently depending on its source: currently, interest is taxed at your full marginal rate, dividends receive preferential treatment via gross-up and the dividend tax credit, and capital gains are taxed on half the gain earned. This section compares the main categories, shows how Alberta provincial tax interacts with federal calculations, and highlights practical implications for after-tax yield. Read the short comparison table to quickly see relative tax impact and then review examples in the subsections that follow. Understanding these distinctions helps you choose accounts and strategies that reduce taxable exposure while preserving returns.

What Taxes Apply to Interest, Dividends, and Capital Gains in Alberta?

Interest income is fully taxable at your marginal rate because there is no preferential adjustment; this makes interest-generating investments relatively inefficient for high-marginal-rate taxpayers. Eligible Canadian dividends receive a gross-up and a federal/provincial dividend tax credit that reduces payable tax, improving their after-tax yield compared with interest. Capital gains benefit from the inclusion rule — currently 50% of the gain is taxable — which effectively halves the tax burden compared with interest on the same nominal return. These mechanics mean that for many Albertans, a dividend or capital-gains-focused approach often beats interest-bearing strategies on after-tax terms.
