What our customers say

Orion Mott (Orion The Healer)

Purvish is a knowledgeable accountant with a great work ethic, and he's really good at figuring out answers to complex questions. I highly recommend him to anyone looking at growing their business in Canada.

Hussein Kermally

The team at Adian is incredibly professional and knowledgeable in accounting and beyond -- they really understand business. They have been managing our accounting needs for the past 3 years and over that time, our company has gained a tremendous amount of confidence in our financials, compliance, and growth.

Lee Brooks

I started my B2B tech marketing business in 2018 and have relied upon Purvish Shah (Adian Professional Corporation) for accounting guidance and tax expertise. I'll assume that any accounting company can crunch the numbers and navigate the corporate tax code correctly. What was important for me—and a real difference-maker with my fledgling business still finding its legs—was knowing my options and being sufficiently informed to choose the most appropriate approach. In that regard, communication and clarity were crucial, and Purvish excels at both. With patience and attention to detail, Purvish took the care and time to provide the overall context for each point of consideration. Moreover, in each discussion he thoroughly explained the available options and their potential trade-offs, and subsequently verified my comprehension. And—something I’m sure any busy professional can appreciate—Purvish clearly identifies action items and deadlines/dates within the larger process, leaving nothing uncertain. Finally—although perhaps a less important point for some potential clients—as a new business owner I appreciated his suggestions and tips for different online tools and services to simplify/expedite my business operations. In summary: I could not be happier with Purvish/Adian, and I would not have made it through my first year of business without his services. /Lee

Fletcher Johnson

My wife and I recently switched our corporate tax accountant to Purvish Shah (the CA behind Adian Professional Corporation), based on a personal recommendation. We are very glad we did so as our experience with his services so far has been nothing short of superb. Not only are his fees competitive, but the reasoning behind his billing is transparent and more than fair. Purvish's communication skills are excellent and he is quite adept at translating complex accounting problems to an understanding more amenable for our lay minds. He is readily available, and we have never had trouble quickly getting a hold of him whenever the need arose. We have full faith that Purvish has our best interests at heart, and that my wife's corporate tax is in expert hands!

United Entertainment DJ

I must say that I have dealt with several accounting firms since the start of my business but none have compared with the great experience I had with Purvish and his company! Purvish was referred to me by a friend who also uses his services and I will also for sure pass on his contact info to all my friends and family. He's very professional, knowledgeable, offers great advice and is amazing at following up. I highly recommend Adian Professional Corp, you will have someone who makes you feel at ease, specially with your taxes as we all know that can be very stressful!

Keith MacDonald

Purvish was very professional, responsive and provided great tax planning advice for us. It's a pleasure doing business!

Adam Petersen

Purvish has been a pleasure to work with and has made my business tax filing straight forward. He clearly explains all that is needed to ensure nothing is missed in the filing process. Would highly recommend.

northernpike13

Purvish is a really great person to work with. He is honest and blunt when he should be but also friendly and easy to talk with. He really knows small business accounting and I highly recommend consulting with him. We have had experience with large accounting companies that do not provide the one on one service that Adian will.

Joseph Shum

Purvish did a great job explaining the filing process to me in detail and answered all my questions promptly. I definitely would recommend working with Adian Professional Corporation.

Teresa Tam

Purvish has been extremely helpful and patient. He made filing my taxes a stress free experience. I would highly recommend working with him for any of those needs.

Frequently Asked Questions

How much does a small business accountant cost in Mississauga?

At Adian, a combined T2 and T1 package starts at $2,250 CAD + HST, a T2, T1 and CSRS 4200 compilation package starts at $3,500 CAD + HST, and the same package with 12 months of Tax-Ready Bookkeeping starts at $5,900 CAD + HST. Every fee is fixed and confirmed in writing.

Does every corporation need to file a T2 return?

Yes. Every corporation resident in Canada must file a T2 corporate income tax return each year, even if it had no income, no activity or a loss. Late filing triggers CRA penalties of 5% of the balance owing plus 1% per month.

When is a T2 corporate tax return due?

A T2 is due six months after your fiscal year-end, so a December 31 year-end files by June 30. Any balance owing is generally due two months after year-end, or three months for qualifying CCPCs.

Can you work with me if I am not in Mississauga?

Yes. Our process is fully remote, so we serve incorporated businesses across Canada except Quebec. Clients upload records securely, review drafts online and approve returns before we file them electronically with the CRA.

What happens if I have not filed taxes for several years?

The CRA can assess penalties, interest and arbitrary assessments. Our catch-up tax filing service prepares overdue T1 and T2 returns in the right order. See what happens if you don't file taxes in Canada.
