## Understanding the New First Marginal Rate
Starting **July 1, 2025**, the lowest federal personal income tax rate dropped from **15 % to 14 %**, under Bill C-4. This rate now applies through the 2026 tax year and beyond, altering how individuals map out deductions, non-refundable credits, and withholding strategies.

## Implications & Planning Opportunities
### Non-refundables and Deductions
Because many non-refundable tax credits are multiplied by the first marginal rate, the reduction increases the value of credits like the basic personal amount, age amount, etc. For example, a credit worth \$1,000 now saves you **\$140 in tax** rather than \$150 if entirely in the first tax bracket. Over time, this modest lift adds up if multiple credits apply.
### Income Timing & Withholding
If you expect income to push you into higher brackets only toward year-end, you might defer income to capitalize on more income taxed at 14 %, or accelerate deductions into high-rate periods. Employers and payers should note the CRA’s updated source deduction tables; withholding rates may now reflect the lower first bracket where applicable. This can improve cash flow throughout the year.

### Families & Two-Income Households
Two-income families often split earnings across spouses. With the lower rate, shifting more income to the spouse with income still within the first bracket can save tax overall. Also favorable are income splitting strategies where permitted, or investment income placed in lower taxed accounts or vehicles.

## Practical Examples
- **Individual taxpayer**, taxable income \$55,000: Previously, the first \$57,375 taxed at 15 % – now taxed at 14 %; that’s **\$167.25 saved** on that portion.
- **Family of two earners**, one earning \$40,000 (stays fully in first bracket), the other \$70,000: more of the combined income taxed at 14 % instead of 15 %, adding up to ~\$334 in savings for the higher earner’s first bracket portion.

## Action Steps You Should Take
1. Review your **withholding or instalment payments** to adjust to new rates and avoid overpayment or underpayment penalties.
2. Ensure tax software or accountant uses updated tables and rules under Bill C-4.
3. If you’re buying a home for the first time, check eligibility for the **GST rebate**, especially homes up to \$1 million or between \$1-\$1.5 million.

4. Revisit your investment portfolio: capital gains subject to higher inclusion (if above the \$250,000 threshold) should be timed considering the rate shift. (But note: only the first bracket rate dropped.)

## Risks & Things to Watch
- Changes in provincial rates may offset federal savings.
- If you defer income, ensure that doing so doesn’t push the income into higher brackets in future years.
- Be cautious with GST rebate eligibility: deadlines and agreements of purchase may affect eligibility.
- Ensure updated CRA guidance is followed to avoid reassessment or conflicting tax positions.
**Bottom line**: The cut in the first federal tax rate to 14 % gives all taxpayers more take-home pay and increases the value of deductions and non-refundable credits. Strategic timing of income and expenses, along with awareness of credits, can yield real savings.
