Since 2004, Advanced Tax has been a leading CPA firm in Canada, helping SMB businesses navigate complex CRA compliance, precise bookkeeping, tax strategy, and more.

"The service I received from Advanced Tax was impeccable, they took care of my personal taxes very quickly. The process was smooth and helped me identify some areas I could even claim back that I hadn't been aware of for years! Since dealing with them myself and trusting the experience I now recommend them to my own clients looking for reliable accounting services for themselves and their businesses."

"Amazing customer service! I found Advanced Tax to be really helpful, informative, caring, and fairly priced. They take care of all necessary tasks in a very timely manner and have provided me with really helpful advice. If you need an Accountant who truly cares and is reasonably priced, look no further than Advanced Tax!"

"Azim was great as the external accountant for our firm. He took an active and engaged part of our books, and improving their structure year after year. With his and his firm's guidance and support, we (a medium sized construction firm) were able to go from merely doing year-end reports to generating our own quarterly reports in house and generally improve our accounting practices all around."

"I cannot say enough good things about this accounting company... completely changed my attitude towards book-keeping and my outlook on my taxes... I no longer dread the tax season coming... If you have any questions about what you should do to save more money on your tax bill, or how you can be more organized to make the tax season less stressful, don't delay - get Azim Dahya & Company on your side!"

"We have been with Advanced Tax Services for a few years now and we couldn't be happier with our experience. Khizer and his team help us with bookkeeping, payroll, taxes for two companies, and our personal taxes. All is impeccably done and Khizer takes the time to talk to us and advise us whenever necessary. We highly recommend their services without reservation."

"Fantastic service. Helped us tremendously with our tax filing and in the process saved us a great deal of money. Khizer was very professional and went above and beyond to help us understand the various tax deductions and contributions we needed to apply to our returns. We highly recommend them."

"I had an excellent experience with Khizer for my tax preparation this year. They were professional, knowledgeable, and thorough throughout the entire process. They took the time to answer all of my questions and provided valuable advice to help me save money on my taxes. I appreciate the attention to detail and care that they put into my tax return. I highly recommend them to anyone in need of tax preparation services."

I’ve been working with Khizer for the last couple of years and this guy has been absolutely amazing. He makes the process friendly, quick and painless. He has gone the extra mile and I couldn’t be happier.

Frequently Asked Questions About Corporate Tax Filing in Mississauga, BC

How often should I meet with my corporate tax accountant?

The right meeting frequency depends on your business and how complex your tax situation is. Some businesses only need annual or quarterly check-ins, while others benefit from more regular support. Meetings don’t always need to be in person. Phone calls, emails, or video meetings work just as well. The key is staying in touch throughout the year so tax planning isn’t left until year-end.

What should I look for when choosing a corporate tax accountant?

Look for an accountant with experience handling corporate taxes, a strong understanding of CRA regulations, and familiarity with your industry. Working with a CPA can provide added confidence, as CPAs are held to high professional standards. It’s also important to choose an accountant who offers the level of accessibility you want, whether that’s in person, virtual, or a mix of both.
