About Advotax Law

Advotax Law Professional Corporation is a small Toronto tax law firm, with its office in the Islington City Centre West area of Etobicoke. Tax law has been the firm's lawyers' main focus of practice for over 20 years. Founder Anna Malazhavaya graduated from Osgoode Hall Law School in 2007, was called to the Ontario bar in 2008, and worked at one of Toronto's largest Bay Street firms before starting the practice. The team represents individuals and businesses at CRA audits and appeals, the Tax Court of Canada, the Federal Court and the Federal Court of Appeal, on matters that span income tax, GST/HST, cryptocurrency taxation, cross border tax, real estate assignment sales and voluntary disclosures.

The firm describes its aim as Bay Street quality legal service at Main Street prices, and says it works with real estate and construction contacts in both the Greater Toronto and Greater Vancouver areas, plus out of province clients who book by video call. One member of the team holds a PhD in tax law from McGill University and teaches tax law at a Canadian law school. Another team member's background includes international tax work in Russia and client service in English, French and Russian. Malazhavaya also founded Canadian Tax Nerds, a discussion and study group for tax professionals that has grown to more than 1,800 members.

The neighbourhood

Advotax Law's office is in the Islington City Centre West part of Etobicoke, at The Queensway and North Queen Street, in a building the listings describe as office space within walking distance of malls, restaurants and shopping rather than a courthouse district. That fits a practice built around written CRA submissions and Tax Court filings more than daily walk in appearances. The building also has quick access to Highway 427 and the QEW, useful given the firm says it works with real estate and construction contacts in both the Greater Toronto and Greater Vancouver areas and books many client meetings as video calls rather than in person visits.

Frequently asked questions

I'm being audited by the CRA. Can Advotax Law help?
Yes. The firm says it helps clients respond to audit inquiries, prepares supporting documentation, communicates directly with the CRA, and works to resolve issues before they escalate into reassessments, penalties or interest. It handles audits across income tax, GST/HST and payroll matters.
I found mistakes in old tax returns and I'm worried about penalties. Can Advotax Law fix this before the CRA catches it?
The firm works with clients and their accountants on the CRA's Voluntary Disclosures Program to correct prior years' filings and pay overdue tax while seeking protection from penalties. If a disclosure application is denied, the firm says it can challenge the decision through a judicial review application to the Federal Court.
Does Advotax Law handle cryptocurrency tax questions?
Yes. The firm says it helps classify crypto transactions as capital gains or business income, calculates gains and losses and cost bases, identifies eligible GST/HST input tax credits, and represents clients during CRA crypto audits, including responding to CRA questionnaires.
I'm assigning a pre-construction condo before closing. Will I owe HST and income tax on the profit?
The firm's real estate and tax practice advises builders, investors and landlords on CRA audits and reassessments tied to property transactions, and it has published a free calculator on its site to give a general estimate of the combined HST and income tax exposure on an assignment sale. The firm says the calculator is educational only and recommends a consultation for an actual assessment.
Can Advotax Law represent me at the Tax Court of Canada?
Yes. The firm describes guiding clients from responding to a CRA audit through notices of objection, settlement negotiations and, where needed, representation before the Tax Court of Canada, the Federal Court and the Federal Court of Appeal.
How do I book a consultation with Advotax Law?
The firm's website has a Book a Consultation option that opens an online scheduler for a 60 minute video call. Its office is at 300 North Queen Street, Suite 205N, in Toronto.
