Part III.1 tax
A corporation that designates dividends as eligible dividends that exceed its capacity to pay such dividends is subject to Part III.1 tax. The tax is equal to 20% of the excessive eligible dividend designation.
Use Schedule 55, Part III.1 Tax on Excessive Eligible Dividend Designations, to calculate any Part III.1 tax payable and file it with your T2 return.
On line 710 of the return, enter the amount of Part III.1 tax payable.
Note
Every corporation resident in Canada that pays a taxable dividend in the year, other than a capital gains dividend, must file this schedule.
In the case where an excessive eligible dividend designation is determined to be part of a tax avoidance scheme, the 20% tax plus an additional 10% tax will apply to the whole dividend designation.
