Real feedback from the people we work with, straight from Google.
Elijah was super helpful with my 2025 taxes both personal and business. I got all questions answered especially as newly transitioning into GST filing.
Great service! Came to them after using H&R block and they were able to get me a considerably bigger refund.
I had an excellent experience working with Sardius Accounting this year. The level of detail and thoroughness in my tax return was the best I’ve had since I started filing my taxes in Canada.
Sardius has handled my tax filing since I came to Canada 6 years ago and they're so effective and accommodating that I have not thought to do it myself.
Great service provided by Sardius Accounting. I have peace of mind about my corporate tax, both income and GST. I highly recommend their services
I would highly recommend this accounting firm! Elijah has been my accountant for over a decade.
I recently filed my taxes with Sardius Accounting and I am truly impressed with the level of service this company provides. From start to finish, the experience was seamless and professional.
I have been a loyal client of Sardius for the past 6 years, and their services have been nothing short of exceptional.
I was hesitant at first, but Elijah assisted me in gathering all the necessary documents, which made everything much easier. The entire process was smooth and stress-free. Highly recommend!
I can confirm that they are the best when it comes to tax solutions and very affordable too
I've been using Sardius for about 4 years now. I'd go nowhere else. Elijah is very knowledgeable, professional, and timely! He's organized and helps me stay organized.
I have had the pleasure of utilizing the accounting services provided by Sardius Accounting to handle my tax filing for the past 7 years, and I must say that it has always been an outstanding experience, consistently.

Frequently asked questions
What documents do I need for my personal tax return?
Bring your tax slips (such as T4, T5 and T3), RRSP and other contribution receipts, medical, donation, childcare and tuition receipts, and last year’s notice of assessment. If you are self-employed or own rental property, also bring your income and expense records. Not sure what applies to you? We will tell you what is needed.
How much does a tax return cost?
Our starting prices, before GST, are $100 for a personal return, $200 for self-employed or rental income, and $1,450 for a corporate year-end (T2). Your final fee depends on how complex your situation is, and we confirm it before we begin.
When are personal and corporate tax returns due?
Personal returns are generally due April 30, and self-employed individuals generally have until June 15 to file, though any balance owing is still due April 30. A corporation generally must file within six months of its year end, and payment is generally due earlier. Contact us if you are unsure about your dates.
I am new to Canada. Can you help me file?
Yes. We walk newcomers through each step, explain the slips and credits that apply, and make sure your first return is filed correctly.
Can you help if I received a letter from the CRA?
Yes. We help you understand the notice, prepare your response and deal with the CRA on your behalf, including reviews and audits.
I think a past return missed something. Can it be fixed?
Often, yes. We review prior years and file for a reassessment when a refund or credit was missed.
Do you work with incorporated professionals and business owners?
Yes. We prepare corporate returns and GST filings, and we plan with you how to pay yourself and what to keep in the corporation. We also offer bookkeeping, payroll and part-time CFO and controller support.
