What does a tax lawyer do?

Tax lawyers advise on income tax, GST/HST, disputes with the Canada Revenue Agency, and the tax side of business deals and estate planning, and they represent clients in tax appeals.

Income tax is mostly federal, administered by the Canada Revenue Agency, with provincial tax layered on top for certain matters.

How do you choose the right firm in Longueuil?

Ask whether the firm handles planning, disputes, or both, and how it'll work with your accountant so advice and filings stay aligned.
