An overview of your financial situation, tax insights, and custom recommendations.
Corporate tax filing costs vary based on business complexity, transaction volume, and the scope of services required. A straightforward incorporated business with basic bookkeeping might pay differently than a corporation with multiple shareholders, foreign income, and complex tax situations. We provide detailed quotes after a complimentary consultation where we understand your specific needs. This approach ensures you pay for the exact services you need without unnecessary add-ons. Rather than guessing from a price list, we prefer to understand your situation and provide accurate, customized pricing.
If your business is incorporated, proper bookkeeping is essential — not optional. The CRA requires corporations to maintain accurate financial records, and Clean books make corporate tax filing significantly easier while enabling you to make informed business decisions. Even if you are a sole proprietor, organized bookkeeping helps you track profitability, manage cash flow, and reduce stress at tax time. We offer various service levels to match your needs and budget, from basic month-end reconciliation to comprehensive full-service bookkeeping.
The CRA requires corporations to keep financial records for a minimum of six years from the end of the last tax year they relate to. This includes all source documents supporting income and deductions — invoices, receipts, bank statements, contracts, and payroll records. We help our clients establish record-keeping systems that make this requirement manageable rather than overwhelming. Good systems also make your bookkeeping more efficient and reduce the time required for year-end accounting.
Yes, HST filing services are one of our core offerings. We handle GST/HST returns for businesses across all filing frequencies — monthly, quarterly, and annually. We also analyze transactions to ensure you are claiming all available input tax credits while maintaining full CRA compliance. Many of our clients tell us they never want to manage HST filing themselves after seeing how efficiently we handle it.
Absolutely. The majority of our clients are incorporated businesses requiring T2 corporate tax filing, corporate bookkeeping, and related compliance services. We have extensive experience with Ontario corporations of all sizes — from single-shareholder-owner corporations to multi-shareholder structures with complex corporate tax situations. Our expertise includes Canadian-controlled private corporations (CCPCs), professional corporations, and a variety of other corporate structures common in Ontario.
We use cloud-based accounting software that allows us to work efficiently with clients anywhere in the GTA — including Oakville, Burlington, Mississauga, Milton, and Toronto. Whether we connect remotely for virtual meetings or you prefer in-person sessions at our Oakville office, we maintain seamless communication and document exchange. Many clients appreciate the flexibility of hybrid services: local drop-off capability combined with modern digital workflows.
A local accounting firm offers several advantages: easier in-person meetings when needed, better understanding of local business conditions, responsive service without waiting for callbacks from distant offices, and community accountability. When you work with Campos Tax, you are not just another client number in a database — you are a valued member of our business community. We have built relationships with local banks, lawyers, and other business professionals who often refer clients to us because they trust our work.
Yes, we offer both in-person and virtual consultations. Many of our GTA clients prefer virtual meetings for ongoing work because they save commute time while maintaining the same quality of service.

Whether you are in Oakville or Mississauga, you receive the same expertise and personalized attention.
