Immediate Changes for Individual & Lower-Income Filers
- Lowest federal income tax rate cut: As of 1 July 2025, Canada lowered its bottom tax rate from 15% to 14%. For the 2025 tax year, because the change came mid-year, the rate for amounts taxed at the lowest bracket ends up being 14.5%. (canada.ca)
- 'Automatic Federal Benefits' program: Beginning with the 2026 tax year, the CRA will automatically file pre-filled tax returns for many low-income Canadians, helping ensure access to credits such as the Canada Child Benefit or GST/HST Credit. Budget 2025 aims to serve up to 5.5 million people by 2028. (budget.canada.ca)
New / Adjusted Small Business and Investment Incentives
- Flow-through share critical minerals expansion: Certain crucial minerals—such as germanium, molybdenum, tungsten—are added to those eligible under the critical mineral exploration tax credit (CMETC). Effective for flow-through agreements after 4 November 2025. (canada.ca)
- Top-Up Tax Credit: Introduced for amounts claimed under non-refundable credits above the first income tax bracket threshold, to cushion effects of rate changes. 0.5% in 2025, rising to 1% from 2026 onward. (canada.ca)
Actionable Steps for Canadian Taxpayers
- Adjust pay withholding: Alle income earned after 1 July 2025 should have lower federal taxes; check your employer uses updated tables.
- Benefit-eligibility check: Low-income individuals should ensure the CRA has correct information to make them eligible for auto-filing or programs like Automatic Federal Benefits.
- Investment planning: Investors looking at critical minerals via flow-through shares can plan acquisition timing to ensure eligibility for expanded credits.
- Small business/farm operators: Investigate how Lifetime Capital Gains Exemption (LCGE) now operates; some changes in inclusion rates were confirmed not proceeding. (canada.ca)
Example Scenario
A single Canadian with taxable income in the lowest bracket will see their income taxed at 14% for income earned after 1 July 2025, reducing taxes owed and increasing net pay. An investor investing in a flow-through share issuing germanium will benefit from the expanded CMETC, potentially lowering taxes on mining exploration expenses. A low-income individual, who previously did not file returns because they weren’t required, may receive automatic benefits when their income tax return is pre-filled and submitted by CRA.
Summary
Canada’s latest tax changes offer tangible relief for individuals at lower income levels, boost incentives in resource sectors, and simplify benefit access. Understanding these shifts early helps both personal taxpayers and business owners make informed decisions in the 2025-26 tax year.
