Option 1
Filing approach
File return using new 2/3 capital gains inclusion rate but proposals do not pass into law.
Interest implications
If the proposals do not pass, expect a refund of excess taxes paid plus interest at the prescribed rate (Q1 2025 non-corporate overpayments – 6%, corporate overpayments – 4%).
For individuals, including trusts, interest accrues from the latest of:
- May 30; (30 days after the return due date for trusts)
- 30 days after the day return was filed
- The day overpayment arose.
For a corporation, interest accrues from the latest of:
- 120 days after the end of the corporation's taxation year
- 30 days after the day return was filed, unless filed on or before due date
- The day overpayment arose.
Interest received must be reported as income of the taxpayer. However, if the proposals pass, there will be no adjustment to taxes and no interest for an overpayment of taxes if you filed using the proposals and the 2/3 inclusion rate where applicable.
Option 2
Filing approach
File return using 1/2 capital gains inclusion rate and proposals pass into law.
Interest implications
If the proposals do pass, it will be necessary to amend your return and pay additional taxes owing plus interest at prescribed rate (Q1 2025 – 8%).
Interest accrues from balance-due day, which is:
- For a trust, 90 days after end of the year
- For an individual, April 30
- For a corporation, two months after end of taxation year, or three months for eligible CCPCs
In addition, under-paid taxes can lead to under-paid instalments, and then under-payment interest and penalties will also apply. ( See Maximize efficiency when paying income tax in instalments).
This interest paid is non-deductible.
If the proposals do not pass, and you have filed using 1/2 inclusion rate, there will be no interest charge for underpaid taxes.
