How much does a charity or NPO audit cost in Canada?

Canadian NPO audit costs typically range from $4,500 to $50,000+ depending on revenue size, asset complexity, restricted funds, and audit scope. Use our free estimator to get a personalized range based on your organization's specifics.

Do I need an audit for my Ontario NPO?

Under ONCA, Ontario non-profits with annual revenue over $250,000 are generally required to obtain an audit. Below that threshold, a review engagement may be sufficient. Funders, lenders, and your bylaws may impose additional audit requirements.

What's the difference between an audit and a review engagement?

A review provides limited assurance and typically costs 40-60% of an audit. A full audit provides reasonable assurance with substantive testing. Only LPA-licensed CPAs in Ontario can perform either engagement.

Why does NPO audit cost vary so much?

Cost drivers include: revenue size, number of programs, restricted/endowed funds, investment portfolios, real estate holdings, international activity, intercompany loans, and bookkeeping quality. Each adds audit hours.

How can I reduce my audit cost?

Keep clean monthly bookkeeping; reconcile bank/investment accounts monthly; maintain a complete general ledger; document board policies and procedures; and prepare a year-end audit working paper file in advance. Quality preparation can reduce audit hours by 20-40%.

How the estimator works

Our calculator starts from a base audit fee tied to your annual revenue band, then layers in complexity multipliers for assets that drive extra audit hours (investment portfolios, restricted funds, real estate, international activity, etc.). Foundations and multi-program organizations get small adjustments. We surface a range — not a single number — because every NPO has unique books, controls, and scope considerations.

What changes your final price

Bookkeeping quality: Clean monthly reconciliations can reduce audit hours by 20-40%.
Internal controls: Documented segregation of duties shortens our control testing.
Prior auditor working papers: First-year audits typically cost 10-15% more.
CRA/funder reporting: Additional schedules (T3010, funder-specific reports) add scope.
Year-end timing: Off-peak engagements (not Dec/Mar) may receive better pricing.

This tool provides general estimates only and is not a binding quote. Every NPO audit engagement is unique. Pricing depends on bookkeeping quality, internal controls, audit scope, and other factors.
