1.02 Personal tax-return changes

Reduction in lowest federal marginal rate

Effective July 1, 2025, the lowest federal personal income-tax rate decreases from 15% to 14%. For the full 2025 taxation year, this produces an approximate blended effective rate of 14.5% for the lowest bracket.

All federal brackets and most non-refundable credits are indexed for inflation for 2025.

Key dates

Item	2025 filing season
T1 filing deadline (most individuals)	April 30, 2025
T1 filing deadline (self-employed and spouses/common-law partners)	June 15, 2025 (automatic extension)
Balance due for most individuals	April 30, 2025 (interest accrues after April 30)
T2 corporate return due date	Six months after fiscal year-end

Automatic extension for self-employed individuals

Self-employed taxpayers and their spouses/common-law partners automatically qualify for an extended T1 filing deadline of June 15.

How the extension works

Under the Income Tax Act, where either the individual or their spouse/common-law partner carries on a business in the year, the return is generally considered timely if filed by June 15.

Important reminder

All tax balances remain due by April 30. Interest is charged after April 30 even if the return is filed under the extended deadline.

Additional personal measures

Expanded trust-reporting requirements.
Enhanced anti-avoidance rules.
Proposed capital-gains inclusion-rate changes deferred to 2026.

Corporate tax-return changes

Filing and payment deadlines

Corporate T2 returns remain due six months after fiscal year-end. Instalment requirements remain unchanged.

Electronic filing changes (effective 2025)

Beginning in 2025, updated CRA schema/XML and new validation mechanisms apply for certain information returns.

Corporate tax-rate environment

No major changes to the federal corporate rate are expected for 2025; however, provincial differences and newly introduced credits may still influence planning.

Additional corporate measures

Updated CRA audit-selection criteria.
Deferred capital-gains inclusion-rate increases until 2026.

1.03 Planning considerations for 2025

Review 2025 projected income with attention to mid-year rate changes.
Reassess instalments, payroll deductions, and credit eligibility.
Ensure systems comply with updated electronic-filing standards.
Strengthen documentation for deductions and credits.
Begin organizing tax information early to avoid penalties and delays.
