Tax Planning Strategies: Making the Most of 2025’s Tax Changes

1. Adjust Your Withholding and Instalments

Take advantage of the mid-year tax rate cut by ensuring your employer is using the updated 2025 tax tables: - Starting July 1, 2025, your employer should withhold federal tax at 14% on the first portion of your salary, instead of 15%[13]. Verify your July paystub to see the slight increase in net pay. If it wasn’t adjusted, alert payroll – you are entitled to the reduced withholding for the second half of the year. - If you pay tax by quarterly instalments (common for self-employed or investors), adjust your Q3 and Q4 2025 instalments downward to reflect the rate cut. The CRA instalment reminders might not fully account for the mid-year change. Paying a bit less (or nothing at all in later instalments if you’ve met your required total) could improve your cash flow, as long as you will meet safe harbour rules. - With higher credits like the Basic Personal Amount in 2025, consider updating your Form TD1 with your employer if you have personal amounts or deductions not previously claimed. For example, if you’re now eligible for the disability credit or will have significant tuition amounts transferred to you from a child or spouse, recording these on your TD1 can reduce tax at source.

2. Optimize Use of Tax Credits

Make sure you maximize the benefit of increased and new tax credits: - Basic Personal Amount (BPA): The federal BPA is larger in 2025[9], and Ontario’s BPA is larger as well. While this is automatic when you file, you should also ensure any secondary employer or pension payer is not giving you the full personal amount if you already claimed it on primary employment – otherwise you might under-withhold. Use the higher BPA strategically on the income source where it helps most. - New Top-Up Tax Credit: If you anticipate very large non-refundable credits (like a big medical expense claim or tuition carryforward) that might exceed your taxable income in the lowest bracket, rest easy knowing the Top-Up Tax Credit will protect you[15]. Strategy: Don’t delay claiming credits out of fear of losing value. 2025 is a good year to utilize carried-forward credits (like prior year tuition or donation carryforwards) because the 15% value is effectively locked in for excess credits via the top-up. This ensures you get full benefit now. - Charitable Donations: Federal and Ontario donation tax credits remain generous (federal 29% on amounts over $200, plus provincial credits ~11-17%). With the first bracket rate dropping, the spread between the donation credit (which is at 15%/29% federally) and your marginal rate might actually increase if you’re in a lower bracket. Strategy: If you’re charitably inclined, consider donating securities in-kind to eliminate capital gains and get a donation receipt. Also, couples can consolidate donations on one return to get past the $200 threshold for the higher credit rate. - Ontario Credits: If you’re in Ontario and planning or considering fertility treatments, schedule them in 2025 or later to tap the new 25% refundable Fertility Treatment Tax Credit[54]. For costly procedures, a $5,000 refund can significantly offset expenses. Coordinate this with the federal medical expense credit: you can claim both (Ontario’s credit won’t reduce your federal claim). - Medical and Disability-related Planning: The increase in the federal medical expense limit to $2,834[21] means a slightly higher hurdle, but if you or a dependant have large medical costs, try to bunch them in the same tax year to maximize the claim. If you have private insurance, get all claims in by year-end. For disability supports or home renovations (accessibility), remember the federal Home Accessibility Tax Credit offers up to $3,000 back on $20k of renos – if you need to make your home safer or more accessible in the near future, doing so in 2025 could yield tax savings (Ontario doesn’t have a direct equivalent credit, but you’d get 15% federally[23]). - Education Credits: The federal tuition tax credit continues (with the tuition fee amounts typically unchanged). If you’re a student or supporting one: ensure T2202 forms are collected, and consider transferring tuition credits (up to $5,000) from a child to a parent or from a lower-earning spouse to a higher earner if the student can’t use them fully. This is longstanding advice, but with higher bracket thresholds in 2025, a parent might be in a slightly lower bracket than expected – still, it’s usually beneficial to transfer to a parent in at least the second bracket (20.5%) or higher.

3. Maximize Registered Plan Contributions Early

Given the increased limits: - RRSP: Aim to contribute as much as possible towards your $32,490 RRSP limit (if you have it). If you received a bonus or expect one, contributing it to RRSP (or instructing your employer to put a portion to an RRSP) can shelter it from high taxation. The sooner in 2025 you contribute, the sooner tax-deferred growth starts. If cash flow is an issue, you could contribute later or even in the first 60 days of 2026 and designate it for 2025, but be careful not to miss the deadline. - TFSA: Since the TFSA room didn’t jump this year, the key strategy is consistent: contribute early in the year to maximize tax-free investment growth. If you withdrew any TFSA funds in 2024, that amount becomes additional contribution room on Jan 1, 2025. Mark that on your calendar to re-contribute if you intended to put it back. - FHSA: If you’re eligible for the First Home Savings Account and haven’t opened one, consider starting in 2025. You get an $8,000 contribution room for each year of eligibility (carryforward applies once you open it). Even if you’re not sure you’ll buy a home soon, the FHSA offers RRSP-like deductions and TFSA-like tax-free withdrawals – a powerful combo. For example, contributing $8k in 2025 yields a tax deduction (worth up to ~$3k if you’re in a mid-to-high bracket in Ontario) and you can invest that money to grow tax-free towards a home purchase. - RESP: If you have children under 18, don’t forget to contribute at least $2,500 per child to get the full 20% CESG ($500). The federal indexation doesn’t apply to RESP grants (they’re fixed), but the power of compounding still argues to contribute sooner rather than later each year.

4. Plan Income Splitting and Timing

The increase in brackets and credits can influence how you split income or time certain transactions: - Spousal RRSPs: If you have a higher-income spouse and expect to be in a lower bracket (especially with the bracket shifts), spousal RRSP contributions remain a great tool. The higher earner gets the deduction now, and the lower earner can withdraw in future at presumably the new lower tax rates. - Pension Income Splitting: If you’re retired, the federal age credit is bigger and OAS thresholds higher in 2025[19]. Splitting eligible pension income with your spouse can reduce or eliminate an OAS clawback if one of you is over the ~$93,454 threshold[57]. With the threshold up about $2,500 from last year due to indexing, fewer seniors will face clawback. Still, if one spouse is above and one below, splitting can bring both under the limit. - Capital Gains Timing: The Lifetime Capital Gains Exemption (LCGE) for qualified small business shares and farm/fish property increased to $1,250,000 in 2024[58]. If you’re selling a business or farm in 2025, you get that full $1.25M exemption (assuming the sale meets criteria). No further increase in 2025 beyond indexation was noted, but plan sales accordingly. Also, consider the current government stance against increasing the capital gains inclusion rate – the Tax Transparency report notes the proposed hike didn’t happen[59], meaning the inclusion stays at 50% for 2025. This stability allows you to harvest gains if needed without fear of retroactive tax change. - Stock Option Planning: If you’re an employee with stock options, recall that from 2021 the federal government limited the $200k of stock options at the preferential tax rate for large employers. Ontario follows the federal lead. No new changes in 2025 here, but just a reminder to strategize exercise of options around your marginal rate – with the first bracket rate dropping, exercising options that land in your lower income years became slightly more tax-efficient. High earners should be mindful of the Ontario surtax brackets when exercising options; maybe spread exercises across years to avoid bumping into higher surtax in a single year.

5. Use Government Programs to Your Advantage

· Auto-Filing by CRA: As noted, the CRA may start automatically filing returns for certain individuals from 2025[27]. While this is primarily targeted at very low-income individuals who might otherwise not file, it’s a good prompt to encourage family members or friends in that situation to provide updated information to CRA. For example, if your eligible relative receives a letter about auto-file, ensure their marital status or dependant info is up to date with CRA. This will ensure the CRA claims the correct credits (like the Ontario Trillium Benefit or GIS entitlements) on their behalf.

· Stay Informed on Provincial Changes: If you reside outside Ontario, be aware each province has its own 2025 changes. (For instance, several other provinces also index brackets; some, like Alberta, even cut tax rates for 2025.) While our series focused on Canada and Ontario, consider checking your province’s 2025 budget highlights. For example, Alberta introduced a new 8% bracket mid-2025[60], and other provinces have adjusted credits. Align your strategies with your local rules too.

· Tax-Free First Home Savings & Withdrawals: If you’re planning a home purchase, remember you can combine the FHSA and RRSP Home Buyers’ Plan (HBP) in 2025. The HBP lets you withdraw up to $35,000 from RRSP tax-free (to repay over 15 years), and the FHSA up to $40,000 plus growth tax-free (no repayment). A couple could potentially marshal $150k+ (two FHSAs of $40k each + two HBPs of $35k each) if they started early. If home-buying is a goal, strategize contributions accordingly: fill FHSA first (for the tax deduction and flexibility) and use RRSP mainly for HBP if more is needed.

6. Year-End Tax Planning

Finally, don’t forget classic year-end strategies, which 2025’s changes subtly influence: - Tax-loss selling: If you have investments, consider selling losers by December to offset capital gains – the 50% inclusion rate remains, and offsets are dollar for dollar on taxable gains. - RRSP contributions vs. TFSA: With the lowest federal rate dropping to 14% in 2026, RRSP deductions are slightly less valuable for low-income earners going forward. If you expect to always be in a low bracket, prioritize TFSA (tax-free out) over RRSP (taxable out) for new savings. Conversely, higher earners still benefit greatly from RRSPs. - Income deferment: If you can defer a bonus or self-employment income to 2026, note that the first $57k in 2026 will be taxed at 14% instead of 14.5% in 2025 – a small difference, but it’s a guaranteed 0.5% savings on that portion. However, don’t let the tail wag the dog; a half-point difference on part of your income likely isn’t worth significant contortions unless very large sums are involved.

In conclusion, 2025’s confirmed tax changes present opportunities to save. By adjusting your tax withholdings, maximizing use of credits and registered plans, and timing income and deductions wisely, you can keep more money in your pocket. All strategies above are based on enacted rules – no guessing or risky schemes. As always, consider consulting a tax professional for personalized advice, especially if you have a complex situation. With informed planning, you’ll be well positioned to benefit from the tax landscape of 2025.
