Foundational public accounting, audit, financial reporting, and client service. The lasting lessons were discipline, documentation, professional skepticism, and asking the right questions about the business.
Dang & Associates CPA is a Mississauga practice led by Kha Dang. The work is accounting, tax, trust and estates, and practical advice for people who want a long-term relationship with their accountant.

Kha became an accountant because he was drawn to structure, problem-solving, and helping people make confident financial decisions. Accounting, for him, is more than numbers and tax savings. It is understanding how a business works, seeing the risks and opportunities in that situation, and giving the owner information they can use.
Many owners are excellent at serving customers and still feel overwhelmed by accounting, taxes, and payroll. The firm was started so those clients could get professional service with a more personal, advisory approach, and so they could focus on customers and growth.
Kha’s career spans public accounting, international audit, corporate finance, tax, and business advisory. He brings the discipline of large organizations together with the personal attention of an independent practice.
Public accounting, tax, international advisory work, and corporate finance. That mix is what clients get: technical standards and a view from inside a business.
Foundational public accounting, audit, financial reporting, and client service. The lasting lessons were discipline, documentation, professional skepticism, and asking the right questions about the business.
Work in a sophisticated international environment, including complex financial structures and high standards for audit and reporting. That still helps when a client operates in a regulated or complicated setting.
Corporate finance from inside a large organization: budgeting, reporting, controls, and how accounting decisions affect operations, cash flow, and management information.
A practice for individuals, professionals, entrepreneurs, and owner-managed businesses that want reliable guidance. The work Kha is most proud of is the trust clients place in the firm at important moments.
A Chartered Accountant and CPA background covers financial reporting, assurance, tax, and business advisory work. In Ontario, CPAs and accounting firms are overseen by CPA Ontario.
CISA reflects training in information systems auditing, technology controls, and risk. That matters as businesses rely on cloud accounting, digital records, online banking, and connected systems.
CIA reflects internal audit, governance, risk management, and internal controls. For an owner, that means a more disciplined look at process, error, and accountability.
An audit background shapes the firm’s accounting and advice: risk-based, documented, and aimed at catching compliance issues, especially CRA reporting, before they grow. Corporate finance experience adds a practical lens on performance, cash flow, hiring, financing, inventory, and profitability.

The Greater Toronto Area is a diverse, entrepreneurial business community: family-owned companies, professionals, logistics, retail, consultants, and growing corporations. Mississauga is a dynamic place to do that work. Many clients are building something for their families, employees, and customers.
Businesses here often face high operating costs, competitive markets, staffing pressure, rising rent, payroll complexity, HST, and tight cash flow. A local accountant can talk about those conditions, Ontario payroll requirements, and CRA compliance in the same conversation.
Outside the office, Kha values time with family and friends, playing sports, and travelling. Clients and friends describe him as thoughtful, professional, detail-oriented, dependable, and practical.
