FAQ
Many questions are associated with taxation and the work of the tax expert. Here are the answers to the most frequently asked questions.
What does a tax expert do?
A tax expert is the go-to professional when it comes to taxes. They have an in-depth understanding of tax law and work with both individuals and businesses. Much like a lawyer focused on taxation, a tax expert helps with income tax filings and provides strategic advice tailored to each client’s situation. At Effisca, our professionals have many years—often decades—of experience in Canadian, U.S., and international taxation, allowing them to handle even the most complex cross-border cases with confidence.
What is the difference between an accountant and a cross-border tax expert?
An accountant has a broad background in accounting, bookkeeping, and taxation. A tax expert, on the other hand, is focused exclusively on taxation and becomes essential when a case involves multiple jurisdictions—for example, income, property, or compliance obligations that span Canada, the United States, or other countries. The accountant usually focuses on compliance: preparing tax returns and ensuring they meet regulatory requirements. The cross-border tax expert goes further—developing strategies, preparing both Canadian and U.S. tax filings when required, and ensuring the client’s overall structure minimizes double taxation while optimizing tax savings. Both professionals are complementary. In cross-border cases, the tax expert often acts as the strategic coordinator, collaborating with the accountant, notary, or attorney.
How much does a tax expert cost?
Fees depend on the complexity of the case, the time required, and the nature of the engagement. At Effisca, we emphasize transparency—flat fees for standard cases and hourly rates for more technical matters. In most situations, the tax savings achieved far outweigh the cost of the service, making the involvement of a tax expert a smart and profitable investment.
Do I really need a tax expert?
Whenever a case involves complexity—foreign income, dual residency, the sale of Canadian property by a non-resident, or planning a move into or out of Canada—a tax expert becomes invaluable. Cross-border experts identify the strategies and savings opportunities that others might miss. If you’re unsure, our team can quickly assess whether your situation would benefit from a cross-border tax expert.
