What's New for 2025/2026 Tax Year?

Legislative changes and updated limits affect how Canadian businesses should approach year-end planning. Understanding what's changed helps you identify new opportunities and avoid compliance issues.

Key Legislative Changes for Canadian Businesses

The 2025 tax year brings several important changes that impact business owners across Canada. The capital gains inclusion rate remains a critical consideration for anyone planning asset sales or investment portfolio adjustments. Business owners should pay particular attention to how these changes affect their overall tax strategy, especially when considering the timing of capital asset dispositions.

Alternative Minimum Tax (AMT) updates continue to affect high-income business owners and those claiming significant deductions. The expanded AMT base and adjusted exemption amounts mean more business owners may face AMT obligations. This is particularly relevant for those considering large charitable donations or claiming substantial capital gains exemptions.

Small business deduction thresholds and passive investment income rules remain key factors in corporate tax planning. The $500,000 small business deduction limit continues, but passive investment income above $50,000 begins reducing access to the lower small business tax rate. Once passive income exceeds $150,000, the small business deduction is completely eliminated.

Year-End Tax Planning Checklist for Canadian Businesses

Strategic tax planning requires action across multiple areas of your business finances. This checklist breaks down the most impactful moves you can make before December 31, 2025.

Review and Optimize Your Compensation Strategy

The salary versus dividend decision remains one of the most important choices for owner-managers. Paying yourself a salary creates RRSP contribution room and ensures CPP contributions for future retirement benefits. However, dividends may result in lower overall tax in provinces with favorable dividend tax credit rates. The optimal mix depends on your personal tax situation, corporate income level, and retirement planning goals.

Timing your compensation matters as much as the type. Declaring bonuses before year-end but paying them within 180 days allows corporate deduction in the current year while deferring personal tax. This strategy works particularly well when you expect to be in a lower tax bracket next year. Remember that Tax on Split Income (TOSI) rules limit income splitting opportunities with family members unless they meet specific criteria.

Platforms like Venn simplify compensation tracking through automated bookkeeping and real-time financial visibility, making it easier to optimize your strategy throughout the year.

Maximize Deductions and Credits Before Year-End

Every legitimate business expense you claim reduces your taxable income. Review your operations now to identify deductions you might be missing.

• Accelerate planned equipment and technology purchases

• Review and write off uncollectible receivables

• Prepay eligible business expenses and subscriptions

• Maximize vehicle and home office deductions

• Claim SR&ED credits for eligible R&D activities

• Review meal and entertainment expense claims (50% rule)

• Ensure proper documentation for all deductions

Proper receipt capture and expense categorization throughout the year makes year-end deduction maximization much simpler. Without organized records, you risk missing deductions or facing CRA challenges. Modern expense management tools with OCR receipt capture and automated categorization eliminate the year-end scramble to organize receipts and match them to transactions.

Manage Capital Gains and Losses Strategically

Capital loss harvesting allows you to offset gains realized during the year, reducing your overall tax liability. Review your investment portfolio and consider selling underperforming assets before December 31. These losses can offset capital gains from the current year, with excess losses carried back three years or forward indefinitely.

Be aware of superficial loss rules that deny losses if you repurchase the same property within 30 days before or after the sale. This rule also applies if your spouse or corporation acquires the property. For business owners holding investments in corporate accounts, tracking adjusted cost base becomes even more critical when dealing with foreign currency transactions.

The lifetime capital gains exemption for qualified small business corporation shares offers significant tax savings for eligible business sales. Proper planning ensures your corporation maintains its qualification status when you're ready to sell. Multi-currency considerations add complexity, businesses holding CAD and USD accounts must track foreign exchange gains and losses on investment transactions for accurate tax reporting.

Plan Your Charitable Contributions

Charitable giving provides both community impact and tax benefits. The timing and method of your donations can significantly affect your tax savings. Donations made by December 31 generate tax credits for the current year, while donations of publicly traded securities eliminate capital gains tax on the appreciated value.

Corporate versus personal donations require strategic consideration. Corporate donations provide a deduction against business income, while personal donations generate non-refundable tax credits. The optimal approach depends on your corporate and personal tax rates. First-time donors should investigate the first-time donor super credit for additional savings. Ensure you obtain proper receipts from registered charities for all donations.

Review Corporate Tax Planning Opportunities

Corporate structure optimization can generate significant tax savings. The small business deduction reduces tax on the first $500,000 of active business income, but only if you manage passive investment income carefully. Investment income above $50,000 begins reducing your access to the lower rate, creating a powerful incentive to balance corporate investments with other strategies.

Associated corporation rules affect businesses with common ownership, potentially limiting access to multiple small business deductions. Income splitting through family members faces TOSI restrictions but remains possible through legitimate business involvement. Consider whether corporate class shares or estate freezes align with your long-term succession planning.

Bonus accrual strategies allow you to deduct compensation expenses in the current year while deferring the actual payment. This timing difference can provide cash flow advantages while maintaining tax efficiency.

Common Year-End Tax Planning Mistakes to Avoid

Even experienced business owners make costly errors during year-end tax planning. Avoiding these common mistakes protects your tax position and prevents CRA issues.

Documentation failures top the list of expensive mistakes. Missing receipts, inadequate expense descriptions, and poor record-keeping can result in denied deductions and potential penalties. The CRA requires supporting documentation for all business expenses, and reconstructing records months later rarely satisfies audit requirements. Small deductions add up—that $50 software subscription or $100 professional development course matters when multiplied across dozens of similar expenses throughout the year.

Strategic errors can be equally costly. Overlooking capital loss harvesting opportunities leaves tax savings on the table. Improper income splitting that triggers TOSI rules can result in unexpected tax bills and penalties. Some business owners focus solely on federal taxes without considering Alternative Minimum Tax implications, leading to surprise AMT obligations.

The line between personal and business expenses requires careful attention. Claiming personal expenses as business deductions remains a common audit trigger. When in doubt, err on the side of caution. Consider the CRA voluntary disclosure program if you discover past errors—coming forward voluntarily typically results in waived penalties. Modern expense tracking with automated categorization and OCR receipt capture helps prevent documentation issues before they become problems.

How Modern Financial Tools Simplify Year-End Tax Planning

Year-end tax planning is significantly easier when your financial operations are organized throughout the year. Modern financial platforms eliminate the manual work that makes tax season stressful.

The foundation of effective tax planning is accurate, real-time financial data. When your business expenses, receipts, and transactions are automatically categorized and synced with your accounting software, you have a clear picture of your tax position throughout the year, not just in December. This visibility allows for proactive tax planning rather than reactive scrambling.

Multi-currency businesses face additional complexity at tax time. Proper tracking of foreign exchange gains and losses, international payments, and cross-border transactions requires infrastructure that handles multiple currencies natively. Platforms that offer real CAD and USD accounts with automated FX tracking simplify compliance and reduce errors. This becomes particularly important for businesses importing goods, paying international contractors, or managing foreign investments.

Venn transforms these challenges into advantages through automated two-way sync with QuickBooks and Xero, ensuring your books always reflect current transactions. OCR receipt capture provides instant documentation for every expense. Real-time expense categorization eliminates month-end sorting. Multi-currency account management across CAD, USD, GBP, and EUR simplifies international operations. Corporate cards with automatic reconciliation remove manual matching work. Streamlined bill payment and vendor management reduce administrative overhead. Year-end tax planning isn't a December activity when you have the right financial infrastructure in place year-round.

Year-End Tax Planning for Different Business Structures

Your business structure significantly affects your tax planning strategy. Understanding structure-specific considerations ensures you don't miss opportunities.

Sole Proprietors and Partnerships

Sole proprietors face unique tax planning considerations since business income flows directly to personal tax returns. Every legitimate business expense reduces your personal tax burden, making thorough deduction tracking essential. Home office expenses require careful calculation based on the percentage of your home used exclusively for business. Vehicle expenses need detailed mileage logs separating business from personal use.

Canadian-Controlled Private Corporations (CCPCs)

CCPCs offer more tax planning flexibility through the separation of corporate and personal taxes. The small business deduction provides significant tax savings on the first $500,000 of active business income, but requires careful management of passive investments. Strategic salary and dividend planning allows you to optimize both corporate deductions and personal tax rates.

Bonus accrual strategies let you deduct compensation in the current corporate year while deferring personal tax to the following year. Integration between corporate and personal tax planning becomes essential—what benefits the corporation may not always benefit you personally. Consider both levels of tax when making year-end decisions.

Professional Corporations

Professional corporations face specific restrictions on income splitting and ownership structure. While you cannot split income with non-professional family members through share ownership, other strategies remain available. Paying reasonable salaries for legitimate business services and managing compensation timing still provide planning opportunities.

Retirement planning takes on added importance for professionals who often have significant corporate retained earnings. Individual Pension Plans (IPPs) and Retirement Compensation Arrangements (RCAs) offer enhanced retirement savings for high-income professionals.

Frequently Asked Questions (FAQ)

Q: When is the deadline for year-end tax planning in Canada?

A: Most expense-related tax planning strategies must be executed by the end of the calendar year, December 31, 2025. This is the deadline for actions like paying outstanding business expenses, making charitable donations, selling investments for capital loss harvesting, and contributing to your Tax-Free Savings Account (TFSA). However, contributions to a Registered Retirement Savings Plan (RRSP) and a First Home Savings Account (FHSA) for the 2025 tax year have an extended deadline of March 2, 2026 (the 60th day after year-end).

Q: What are the most important tax deductions Canadian businesses should claim?

A: Canadian businesses must maximize all legitimate operating expenses to reduce their taxable income. The most important deductions include: Operating Expenses: Rent, utilities, insurance, supplies, and professional fees (accounting/legal). Wages and Benefits: Salaries, employer-paid CPP/EI premiums, and benefits paid to employees (including owner-managers). Vehicle/Travel: The business portion of fuel, insurance, maintenance, and lease payments (requires a mileage log). Home Office: A portion of rent, utilities, and property taxes if the space is the principal place of business or used regularly to meet clients. Meals and Entertainment: Generally 50% deductible for costs directly related to earning business income.

Q: Should I pay myself salary or dividends as a business owner?

A: The optimal compensation mix (salary vs. dividends) is a complex tax strategy that depends on your personal financial goals. Salary is deductible to the corporation, creates RRSP contribution room, and requires mandatory CPP contributions. Dividends are paid from the corporation's after-tax income, are not deductible, but are taxed at a lower personal rate due to the Dividend Tax Credit and do not require CPP contributions. Many owners use a blend: enough salary to generate required RRSP room and CPP, and the rest as dividends for tax efficiency.

Q: What is the small business deduction and how do I qualify?

A: The small business deduction (SBD) is a crucial incentive that reduces the federal corporate tax rate on the first $500,000 of active business income. Eligibility: The corporation must be a Canadian-Controlled Private Corporation (CCPC). Active Income: The income must be earned from active business operations, not passive investments. Passive Income Limit: The SBD limit begins to be reduced if the corporation's passive investment income exceeds $50,000 and is completely eliminated if passive income reaches $150,000.

Q: Do I need to keep receipts for all business expenses?

A: Yes. The Canada Revenue Agency (CRA) legally requires that you retain adequate supporting documentation (receipts, invoices, contracts, bank statements) for all claimed business expenses for a minimum of six years from the end of the last tax year they relate to. Failing to produce documentation during an audit will result in the disallowance of the claimed deduction, leading to taxes, interest, and penalties being applied. Digital copies are acceptable provided they are complete and legible.
