Who We Are

Calgary tax consultants Bill Wendy Trevor
Bill, Wendy, and Trevor Cawston have over 70 years of combined tax experience.

Bill Cawston began his career in 1970 working for the CRA. Bill has over 50 years of experience dealing with the CRA both for the CRA and now, for tax payers. In 2008, Trevor joined and later, in 2011, Wendy, a former Canadian Income Tax Auditor and Financial Specialist joined the firm.

Bill says, one of the most common questions we get is, “Will we represent a client from Ontario?” and the answer is yes. We represent clients from across Canada. We offer services to some people who are forced in to bankruptcy due to tax debt.

Our firm does many voluntary disclosures. Call us if you realize there is something for forgot to disclose to the CRA.

We do Section 160 Transfers – this is when the debts of a corporation are transferred to another individual – often a family member.   The CRA must meet four criteria to enforce this section – we have been very successful in protection people who are receiving Section 160 notices from the CRA.

For almost any issue you have with the CRA, the best choice you can to make is to call us first. If your issue is not in our tax area, we will happily refer you to someone who can help.

The Cawston Tax Associates Motto:

I have been in the Tax business for over 50 years. We try to help as many people as we can. Over the years we have helped hundreds and hundreds of people. The problems ranging from unfiled tax returns, unable to pay the Canada Revenue Agency, audit representation, director’s liabilities, voluntary
disclosures, filing notice of objections, bankruptcy consultations, net worth assessments and taxpayer relief under the fairness legislation. They might have owed the CRA a $1000 or $1,000,000. It might have been just a phone call trying to reach the Canada Revenue Agency and we provided the best
telephone number to reach them at. Whatever the issue was that they reached out to Cawston &Associates Inc., we always try and help them. We understand the challenges people are facing today and how covid affected people’s lives and businesses.
