The 5 Best Tax Lawyer Firms in Ottawa

Did you inherit an estate, get into a tax dispute, or start a new business recently? These situations require a different set of taxation skills that you might not be readily familiar with.

It’s better to hire the services of the best tax lawyers in Ottawa to help you understand and not be intimidated by it all. But before doing so, it’s good to be aware of all the fees and costs involved.

How Much Does a Tax Lawyer Charge in Ottawa?

Since tax lawyers handle a myriad of tax-related cases, their fees will also reflect the time, complexity, and other factors involved in each case.

Some tax attorneys will charge an hourly fee or retainer, which is considered the most common pricing structure (even among non-tax lawyers). Others can opt for a block or flat fee, which is typically used for simpler, no-fuss cases.

Meanwhile, clients of modest means can opt for legal aid, which requires a much lower hourly fee than private practices. Other lawyers could even offer pro-bono services to clients they deem deserving of them.

To give you a general idea of other fees, the table below reflects them along with fees that reflect national averages.

TAX LAWYER SERVICEESTIMATED FEE
Hourly retainer$382 – $900 per hour
Legal aid (subject to availability)Less than $100 per hour
Tax Court of Canada appeals$15,000-$30,000 per hour (depending on case complexity)
Law clerk$125 per hour

Please bear in mind that these fees and rates aren’t set in stone, given the range of tax-related issues and varying rates from different firms.

The former lead of HazloLaw’s Tax Dispute and Resolution team formed his own legal team after making his former firm’s tax practice grow by over 300%. Today, Dean Blachford is still the force behind Blachford Tax Law with a practise exclusively focused on tax dispute resolution and litigation.
