Back Tax Preparation in Ottawa

Missed a year or several?

You can book even if some older slips or receipts are missing. Once you authorize us, we can check which tax slips the CRA has on file and help you work out what you still need.

How we help you catch up

Identify the missing years

Tell us the last year you remember filing. With your authorization, we can check your CRA records and work out which returns are outstanding.

Organize your records

We compare the slips available from the CRA with the records you bring and tell you what else to look for, year by year.

Prepare and file

As each year’s information is ready, your accountant prepares the return, explains the result and reviews it with you before filing.

What to bring to your appointment

Gather what you can and group it by year, even if some years have only a few documents.

Your last notice of assessment or tax return

Bring whichever you can find. A notice of assessment can help us request CRA access. Your last filed return helps us see where you left off.

CRA letters

Bring any letters about your unfiled returns. If a letter gives you a deadline, mention the date when you book.

Slips and receipts

Bring the slips and receipts you can find, including medical expenses, donations and child care receipts.

Business or rental records

Bring any income and expense summaries you have, grouped by year.

Please also have photo ID handy for your appointment.

I had a great experience with Zi. They were clear, professional, and responsive throughout the process. I definitely recommend them to anyone needing tax help.
Jack is quick, knowledgeable, and thorough! Everything was taken care of within my 30-minute appointment, and the pricing is very fair. I also appreciated being able to book a phone appointment. It was so convenient, with no waiting around. A great experience overall. Highly recommend!
Kate helped me review my tax forms and made me feel at ease. I followed her suggestions and am pleased with her helping me out. This was on a free 10 minute call and I was very satisfied.
I had a great experience with Sakib at Solid Tax. He prepared and filed my 2023–2025 income tax returns the same day. He answered all my questions in person, and even the follow-up questions I forgot to ask during the meeting, he handled promptly by email. Professional, affordable, efficient, and easy to work with. I plan to keep using Solid Tax through Sakib for all my future tax filings. Highly recommended.
Very friendly and accurate service - all 5 stars for them.
I have used their service for many years to my full satisfaction.

I had a wonderful experience with Solid Tax Inc. this year. My senior tax accountant, Jack Liu, was amazing! We thought sorting our tax information would be a huge headache, but Jack was incredibly thorough, helpful, and patient. He explained everything simply and made us feel completely relaxed. He is a very kind person who turned a stressful process into a smooth, pleasant experience. I highly recommend Solid Tax and Jack Liu to anyone looking for reliable, professional tax services. Thank you again! 😊
I contacted Solid Tax Inc. with concerns about unfiled taxes. Sakib was great; he was able to answer all my questions and filed on my behalf, even correcting previous taxes I filed incorrectly. I strongly recommend him. It was really easy to work with him, especially in a virtual setting, as I didn't even have to go in to have everything done!
Amanda Du was amazing! We could not feel more relaxed. She was very helpful and so patient with sorting our information. We thought it would be a great headache, but, she made it very simple to understand. A very kind and sweet person. Many thanks!!
Worked with Kate this past year. Excellent service, knowledge and customer service at a great price. I highly recommend this company!
I have been using Solid Tax for several years now. I have had no issues and my cash back has been great. They are amazing, kind and kind. I strongly suggest using this service.
