Final answer:
Mr. Smith may not need to report the interest earned from his daughter Emily's GICs on his taxes; Emily might be responsible for reporting it, depending on local tax laws and if she is required to file a tax return.
Step-by-step explanation:
Regarding Mr. Smith's tax obligation for his daughter Emily's Guaranteed Investment Certificate (GIC) interest income, the tax implications may vary based on the jurisdiction's tax laws. Generally speaking, if the investment was made as a gift to a minor child, the interest earned might be attributed to the child, especially if the funds are in the child's name and the child has control over the account. In many jurisdictions, children have tax-free allowances or lower tax rates. Consequently, if Emily earns $320 from the original $3,000 GIC and $32 from the $400 GIC in 2022, depending on local law, it might be Emily who would report this interest income on her taxes, if she is required to file a return at all. Mr. Smith would not report this on his income tax unless the law specifically attributes the interest income of a minor's investment back to the parent.
