Key Highlights
Repeal of Underused Housing Tax (UHT)
The budget eliminates the UHT as of the 2025 calendar year. As a result, no UHT would be payable and no UHT returns would be required to be filed in respect of the 2025 and subsequent calendar years. The budget states that all UHT requirements continue to apply for the 2022 to 2024 calendar years, including penalties and interest.
Introduction of Top-Up Tax Credit
The federal government introduced the middle-class tax cut on May 27, 2025.2 The lowest marginal tax rate was reduced from 15 percent to 14 percent effective July 1, 2025. The lowest marginal tax rate for 2025 will therefore be 14.5 percent and for 2026 and onward will be 14 percent.
The budget introduces a new non-refundable Top-Up Tax Credit that would effectively maintain the current 15 percent for non-refundable tax credits claimed on amounts in excess of the first income tax bracket threshold rate (rather than the 14.5 percent rate for 2025 and 14 percent rate for 2026 and subsequent years). The Top-Up Tax Credit applies for the 2025 to 2030 taxation years.
The budget notes that this measure is intended to address situations in which an individual could have their tax liability increased by the middle-class tax cut (e.g., where an individual claims a large one-time expense, such as amounts for high tuition or medical expenses, or claims a combination of large tax credits).
Personal Support Workers Credit
The budget introduces a temporary Personal Support Workers Tax Credit applicable for the 2026 to 2030 taxation years. This tax credit provides certain eligible personal support workers working for certain health care establishments with a refundable tax credit of 5 per cent of eligible earnings up to $1,100.
Home Accessibility Tax Credit and Medical Expense Tax Credit
Currently, taxpayers can claim both a Home Accessibility Tax Credit (of up to $20,000) for eligible home renovation or alteration expenses, for disabled individuals, in addition to the medical expense tax credit for the same expenditures.
The Budget proposes to deny Home Accessibility Tax Credit for expenses claimed as a Medical Expense Tax Credit (for taxation years 2026 and onward).
This measure prevents taxpayers from double dipping – claiming two separate credits for the same expense.
Elimination of Canadian Entrepreneurs’ Incentive (CEI)
The CEI was announced in the 2024 federal budget and was intended to support entrepreneurs by reducing the capital gains inclusion rate to half of what would otherwise apply. This measure was in response to the announced increase in capital gains rates from 50 percent to 66.67 percent (and reduction in stock option deduction from 50 percent to 33.34 percent) effective June 25, 2024. The CEI was to be phased in over five years with a $400,000 maximum in 2025 and reaching a $2 million maximum in 2029. The proposed changes to the capital gains inclusion rate and stock option deduction did not receive Royal Assent and in January 2025 the government announced a deferral of the effective date of the proposed changes to January 1, 2026.3 On March 21, 2025, the government subsequently cancelled the proposed changes to the capital gains inclusion rate and stock option deduction.4 With the cancellation of these proposed changes the CEI has been eliminated.
