As our Senior Tax Analyst, you will play an important role in supporting the tax function of a rapidly scaling Canadian technology leader. Reporting directly to the Senior Tax Manager, you will gain hands-on visibility across corporate income tax, indirect tax, and ASC 740 provisions, working shoulder-to-shoulder with finance partners, external advisors, and cross-functional teams.

If you have a solid foundation in Canadian corporate tax and want to expand your toolkit into US state/federal, global compliance, and modern tax automation, this role could be right for you.

StackAdapt is a Remote First company; we are open to candidates located anywhere in Canada for this position.

Why You’ll Love This Role

• True Cross-Border Exposure: Transition from Canadian tax into US and international regimes (including T106/T1134 filings, foreign affiliate rules, and multi-state compliance) with hands-on mentorship.
• High-Visibility Collaboration: Work directly with senior leadership, Legal, Treasury, and People teams to see how tax strategy directly influences commercial decisions.
• Innovation & AI: Experiment with AI tools and automation to eliminate manual routine tasks, rethink legacy processes, and streamline reporting.

What You'll Be Doing:

• Tax Accounting & Reporting: Co-lead quarterly and annual income tax provisions under ASC 740, including building/updating provision models, calculating return-to-provision true-ups, preparing audit-ready financial statement disclosures, and liaising with external auditors.
• Global Compliance: Coordinate corporate tax compliance across Canadian, US, and international entities alongside external advisory firms, managing the process from data gathering to review.
• Cross-Border Filings: Support Canadian international compliance, including T106s, T1134s, and foreign affiliate reporting.
• Indirect Tax Management: Support indirect tax workflows across jurisdictions, including Canadian GST/HST/QST, international VAT/GST, and US sales tax.
• Audit & Advisory Support: Assist in drafting responses to tax authority audits and inquiries, working closely with external advisors and internal stakeholders.
• Cash & Forecasting: Manage global tax payments and installments in partnership with Treasury and AP, maintaining real-time accuracy in the cash forecast.
• Operational Modernization: Partner with Accounting, Legal, and HR on entity expansion, and champion the use of AI and automation to enhance tax data workflows.

What You'll Bring to the Table

• Foundational Expertise: CPA designation (or actively pursuing) with 3–5 years of progressive corporate tax experience gained within public accounting or an in-house corporate tax function.
• Technical Foundation: A strong working knowledge of Canadian corporate income tax principles and compliance.
• Nice to Have: Prior exposure to US tax, international tax, indirect tax, or ASC 740 provisions is a definite asset - but not a dealbreaker. If you bring the curiosity and willingness to learn, we’ll provide the coaching and support to get you up to speed.
• End-to-End Ownership: A self-starter mindset with the ability to shepherd projects from data collection to final filing while keeping stakeholders aligned.
• Clear Communication: Ability to distill complex tax concepts into clear, actionable advice for non-tax colleagues across the organization.
• Agility & Curiosity: Comfort navigating fast-paced environments, managing competing deadlines, and continuously asking, "How can we make this process smarter?"
