In our recent white paper, After-Tax Returns, Justin Bender and I introduced a methodology for measuring the effect of income taxes on ETF returns. Justin also created a downloadable spreadsheet you can use to estimate the after-tax returns of funds in your own portfolio.
As we explain in the paper, funds with similar pre-tax returns can look quite different when you compare their performance after the CRA has taken its cut. Remember that on a pre-tax basis investment gains are reported in the same way whether they’re Canadian dividends, fully taxable income or capital gains. If you’re investing in a tax-sheltered account, it’s all the same. But in a non-registered account, distributions are taxed in different ways, and this can dramatically affect the amount of money you actually keep.
Here’s a real-world example that illustrates how large the difference can be. Justin collected the distribution and price data for the iShares Core S&P/TSX Capped Composite (XIC) and the DFA Canadian Core Equity Fund (DFA256) over the nine years ending in 2013. Both funds track the broad Canadian stock market, so you would expect similar returns.
