• As a business owner in Markham or the Greater Toronto Area, you have less than three weeks to capture significant tax-saving opportunities before December 31, 2025. The decisions you make in these final days of the year can reduce your tax bill by thousands of dollars—or cost you those savings if you miss critical deadlines.
• Quick Answer: What You Must Do Before December 31, 2025
• As a Markham business owner, your immediate year-end tax planning priorities include: contributing to registered accounts (RRSPs, TFSAs), claiming charitable donations, harvesting tax losses on investments, accruing business bonuses, and reviewing capital gains. These actions must be completed or initiated by December 31, 2025, to generate tax deductions for the 2025 tax year. Missing these deadlines means losing tax-saving opportunities that won't become available again until 2026.
