Tax

Let us provide you with the insightful and strategic advice needed to navigate the rapidly changing tax landscape. See Overview

Tax planning and compliance
Whether you are a private or public organization, your goal is to manage the critical aspects of tax compliance, and achieve the most effective results. At Grant Thornton, we focus on delivering relevant advice, and providing an integrated planning approach to help you fulfill compliance obligations.
Research & development, government incentives
Are you developing innovative processes or products, undertaking experimentation or solving technological problems? If so, you may qualify to claim SR&ED tax credits. This Canadian federal government initiative is designed to encourage and support innovation in Canada. Our R&D professionals are a highly-trained, diverse team of practitioners that are engineers, scientists and specialized accountants.
Indirect tax
Keeping track of changes and developments in GST/HST, Quebec sales tax and other provincial sales taxes across Canada, can be a full-time job. The consequences for failing to adequately manage your organization’s sales tax obligations can be significant - from assessments, to forgone recoveries and cash flow implications, to customer or reputational risk.
US corporate tax
The United States has a very complex and regulated tax environment, that may undergo significant changes. Cross-border tax issues could become even more challenging for Canadian businesses looking for growth and prosperity in the biggest economy in the world.
Cross-border personal tax
In an increasingly flexible world, moving across the border may be more viable for Canadians and Americans; however, relocating may also have complex tax implications.
International
While there is great opportunity for businesses looking to expand globally, organizations are under increasing tax scrutiny. Regardless of your company’s size and level of international involvement—whether you’re working abroad, investing, buying and selling, borrowing or manufacturing—doing business beyond Canada’s borders comes with its fair share of tax risks.
Transfer pricing
Transfer pricing is a complex area of corporate taxation that is concerned with the intra-group pricing of goods, services, intangibles, and financial instruments. Transfer pricing has become a critical governance issue for companies, tax authorities and policy makers, and represents a principal risk area for multinationals.
Succession & estate planning
Like many private business owners today, you’ve spent your career building and running your business successfully. Now you’re faced with deciding on a successor—a successor who may or may not want your direct involvement and share your vision.
Tax Reporting & Advisory
The financial and tax reporting obligations of public markets and global tax authorities take significant resources and investment to manage. This requires calculating global tax provision estimates under US GAAP, IFRS, and other frameworks, and reconciling this reporting with tax compliance obligations.
