Tax Advisory and Compliance Services for Canadian Businesses
Partner-led corporate, personal, and cross-border tax support for owner-managed and complex organisations.
Tax leadership requires control, consistency, and judgement. Executives need compliance delivered on time, risks identified early, and positions supported with documentation that stands up to review so tax matters do not disrupt operations or strategic plans.
PKF Antares helps organisations and business owners manage tax obligations with clarity and control. We bring structure to compliance, identify and address exposures early, and deliver practical planning that aligns with how the business operates and where it is going.
PKF Antares Tax Services:
Built for businesses with real-world complexity
We work best with organisations where tax decisions affect cash flow, ownership, risk, and long-term outcomes. We support clients across a range of sizes, structures, and tax situations, including:
- Publicly listed companies and organisations subject to securities and public-market reporting requirements in Canada and the United States
- Owner-managed and family-owned businesses
- Professional corporations and incorporated practices
- Organisations with multiple entities, holding structures, or planned reorganisations
- Businesses preparing for growth, financing, or a transaction
- Organisations with GST/HST exposure across provinces or borders
- Companies with US customers, staff, investors, or operations
- Individuals and families balancing business income, investments, and estate considerations
- Non-residents and newcomers navigating Canadian tax obligations
Corporate Tax Planning and Compliance (for Canadian Business)
Corporate tax affects cash flow, ownership decisions, and the efficiency of reinvestment and distributions. When planning and compliance are not aligned, organisations face avoidable tax costs, missed opportunities, and increased CRA risk. Including where planning and compliance considerations intersect with public-company reporting and securities regulatory requirements where applicable.
PKF Antares prepares corporate tax filings and provides planning support that aligns structure and timing to your business objectives. We focus on areas that commonly drive complexity and exposure, including compensation strategy, dividend planning, reorganisations, and transaction readiness. Our objective is to deliver compliant returns and supportable positions that hold up to review. Our focus is on reducing avoidable tax cost and audit exposure while supporting decisions that move the business forward.
Where SR&ED applies, we support claim preparation and documentation to improve audit readiness and strengthen eligibility support.
Support commonly includes: corporate tax returns and compliance, tax minimisation planning, dividend and compensation planning, reorganisations and transaction support, and SR&ED claim support. This includes aligning technical narratives, financial support, and contemporaneous documentation to improve audit outcomes.
Often needed when: you require reliable compliance and planning that improves after-tax outcomes and reduce CRA risks.
Personal Tax and Estate Planning
Personal tax planning is most effective when it connects to how you earn income, invest capital, and structure ownership. Without alignment between personal and corporate planning, tax costs can increase and estate outcomes can become more uncertain.
PKF Antares prepares personal and trust returns and supports owner-managers and families with tax planning for retirement, succession, and estate outcomes. We provide clear options, quantify implications, and help clients make decisions that reflect their goals while managing tax exposure and compliance requirements. We focus on clarity, quantified trade-offs, and decisions that remain supportable over time.
Support commonly includes: personal and trust tax filings, owner-manager tax planning, retirement planning, and estate and succession planning support.
Often needed when: business ownership, investments, or family considerations require more than a standard filing approach.
Indirect Tax (GST/HST)
Indirect tax is a common source of audit activity and unexpected cost. Exposure often arises through incorrect classification, inconsistent filings, weak documentation, or business model changes that create new obligations.
PKF Antares helps clients confirm GST/HST obligations, strengthen filing accuracy, and support positions with appropriate documentation. When CRA reviews occur, we provide audit support and help clients respond efficiently and defensibly. The aim is to reduce disruption, manage risk, and support consistent compliance across operations. Our goal is to reduce disruption, limit reassessments, manage risk, and support consistent compliance as the business evolves.
Support commonly includes: GST/HST registration and filings, indirect tax reviews, input tax credit support, audit defence, and cross-border and multi-jurisdiction GST/HST issues.
Often needed when: you operate across jurisdictions, expand into new markets, or face indirect tax review activity.
International and Cross-border Tax (Planning)
Cross-border tax requirements can create filing, withholding, and residency issues that increase cost and risk when addressed late. Early planning supports clearer obligations, improved coordination, and reduced exposure to double taxation or non-compliance.
PKF Antares supports inbound and outbound structuring, treaty and withholding planning, and ongoing compliance for organisations and individuals with international exposure.
We clarify obligations across jurisdictions, coordinate with relevant stakeholders, and align documentation to the intended outcome to support defensible reporting and timely execution. Early involvement reduces the risk of double taxation, filing gaps, and costly retroactive fixes. (FOL statement)
Support commonly includes: inbound and outbound structuring, withholding and treaty planning, non-resident compliance, and coordination of cross-border reporting across jurisdictions.
Often needed when: ownership, income, operations, or payments involve multiple jurisdictions.
Transfer Pricing (Documentation & Policy)
Transfer pricing applies when related entities transact across borders for services, goods, financing, or intellectual property. Where pricing and documentation are incomplete, authorities may challenge income allocation, apply adjustments, and impose penalties.
PKF Antares helps clients establish transfer pricing approaches that align with business reality and meet documentation expectations. We support method selection, documentation preparation, and practical implementation to reduce audit risk and support consistent reporting across jurisdictions.
Support commonly includes: transfer pricing documentation, method selection and policy design, support for intercompany agreements, and audit support as required.
Often needed when: related entities transact across borders and require supportable pricing and documentation.
US tax (Compliance & Cross-border Planning)
US tax obligations can apply even where the core business is Canadian. Exposure may arise through US customers, employees, contractors, investors, or a US entity. Filing requirements and coordination issues can escalate quickly when obligations are not clearly defined.
PKF Antares supports US personal and corporate tax compliance and planning related to residency, filing requirements, and cross-border structuring. We coordinate the work to reduce gaps, avoid duplicated effort, and support timely, accurate filings. We help clients identify obligations early and avoid compounding compliance risk.
Support commonly includes: US personal and corporate tax compliance, residency and filing obligation support, cross-border planning, and coordination with Canadian reporting.
Often needed when: US connections create personal or corporate filing obligations.

Frequently Asked Questions
Tax compliance focuses on accurate filings and meeting reporting obligations. Tax planning focuses on structuring and timing decisions to reduce exposure and improve after-tax outcomes.
Before year-end. Many planning opportunities depend on decisions made during the year, including compensation, dividends, transactions, and changes to corporate structure.
Risk commonly increases when filings are inconsistent, documentation is incomplete, input tax credit support is weak, supply classifications are unclear, or the business expands into new jurisdictions.
It depends. Requirements can arise based on where work is performed, whether US employees or contractors are involved, how payments flow, and whether withholding or filing obligations apply.
Transfer pricing is how related companies set prices for transactions across borders. Tax authorities expect pricing to be reasonable and supported by appropriate documentation.
Entity structure, jurisdictions involved, key deadlines, prior filings, significant transactions, and any notices or requirements from tax authorities. Where a third party has provided specific requirements, sharing that wording supports efficient scoping and alignment.
