Since 2008, Natalie has dedicated her practice exclusively to resolving tax disputes, providing trusted expertise to private company CEOs and high-net-worth individuals.
Natalie consistently devises innovative litigation strategies, and she has achieved highly favourable outcomes for numerous clients.
Natalie has:
- Overturned a CRA assessment for a $20 million investment portfolio from business income to lower-tax capital transactions;
- Protected the personal interests of corporate directors by shielding them from more than $13 million in HST charges following a corporate merger;
- Successfully challenged CRA reassessments that were denying SR&ED credits and ensured the recognition of similar SR&ED credits for the long term, a vital component of the business's long-term strategy and feasibility;
- Dismantled the CRA's valuation of a property and protected the taxpayer from a $1.7 million tax liability;
- Overturned the CRA's classification and valuation of mining equipment and supplies, leading to savings of over $3 million;
- Demolished CRA's allegations of $10M+ of unreported income and taxable shareholder benefits;
- Overturned the CRA's reassessment and attempt to use the anti-avoidance rules to nullify a legitimate tax planning strategy connected to a low-tax jurisdiction.
Natalie calculated the financial impact of every outcome, kept us informed of the progress, and explained the route that would lead to the best return on our legal fees.
- Jim & Yvonne Schunk, Private Business Owners
