Client Reviews

"I've been coming to Sigma Tax for over three years. They've been one of the best in Ontario — very accommodating, helpful, and consistent with their service."

"I can't say enough good things about Jason and his team at Sigma Tax. I did my taxes later than usual this year and walked in just to drop off my folder. Jason took me in right away and walked me through the whole process on the spot. It was such a relief not to worry about delays or last-minute stress.

What really stood out was how knowledgeable Jason is. He did my return quickly and efficiently, and also gave me great advice I hadn't even considered. I left feeling much more informed and learned a lot just by speaking with him."

"Over 10 years of excellent service! I've been working with Nancy Johal at Sigma Tax on my U.S. taxes for more than a decade and can't recommend her enough. I still drive from Toronto to Oakville every year just to work with her. Nancy is thorough, calm, professional, and genuinely fun to chat with. Highly recommend."

"Jason is a very professional tax accountant. I've been with him for three years and always get a great tax return. See you again soon, sir."

"Jason was very helpful in providing tax advice and making sure I got the best possible refund. My situation was tricky with multiple jobs and overseas employment, but he was informative and personable, and really eased my worries. Great service and easy tax filing. Totally recommend Jason @ Sigma Tax."

"Jason was very helpful, detailed, and found us the best possible tax return. Fees were very reasonable as well."

"I had my taxes done this year with the Sigma Tax team and it was a great experience. My case wasn't straightforward because my husband had just moved to Canada, but the team took care of everything very well. Very efficient, and Jason — the team leader — is especially knowledgeable. Great customer service."

"A friend referred me to Jason at Sigma Tax when I was in a bind and scrambling near the deadline. Jason fit me in, got the job done efficiently, and was incredibly professional with a warm, friendly manner. His fees are very reasonable. I'll definitely continue to file my taxes with him and happily refer others his way."
