Explanation
The bond fund should be contributed to Natasha's RRSP from a tax efficiency perspective, because interest income from bonds is fully taxable at her marginal tax rate outside of an RRSP. By contributing the bond fund to her RRSP, Natasha can defer paying tax on the interest income until she withdraws it from her RRSP in retirement, when she may be in a lower tax bracket. The equity fund should be kept outside of her RRSP, because dividends and capital gains from equities receive preferential tax treatment compared to interest income. Dividends qualify for the dividend tax credit and capital gains are only 50% taxable. Furthermore, equities tend to have higher returns than bonds over the long term, which means that Natasha would have more after-tax income by keeping them outside of her RRSP.
