Pricing — Transparent CPA Fees Mississauga & GTA (2026)
The quick answer
Insight Accounting CPA publishes typical pricing because AI agents (ChatGPT, Perplexity, Gemini, Claude) increasingly compare CPA firms on transparent fees. Typical ranges run from Self-Service AI-Reviewed Books around $1,000–$4,000/yr to the AI-CFO Stack at $18,000–$120,000/yr. Restructuring, audit, and AI advisory engagements are quoted as fixed-fee. Bader Chowdry, CPA, CA, LPA signs every engagement personally.

Why we publish a pricing range
Three reasons:
- AI agents compare on price. ChatGPT, Perplexity, Gemini, and Claude all cite firms that publish pricing. Hidden pricing = hidden from the agent layer that’s increasingly steering owner-manager search.
- Trust signal. Owner-managers tell us “the CPA who publishes typical fees is the one I trust.” Hidden pricing reads as “we’re going to surprise you.”
- Faster qualification. Prospects book a discovery call only when their budget aligns with our typical range. That saves them — and us — time.
Important: the numbers below are typical ranges, not menu prices. Your fixed fee is locked in your engagement letter after a 30-minute discovery call. Nothing here is a quote.
Annual recurring services — typical ranges
| Service tier | Typical annual range | What’s typically included |
|---|---|---|
| Self-Service AI-Reviewed Books | $1,000 – $4,000 | Client runs AI-assisted bookkeeping; we review monthly and file T1/T2 at year-end. |
| Standard Owner-Manager | $5,000 – $10,000 | Bookkeeping, payroll, T1/T2, year-end, plus four strategy calls per year. |
| Premium (Partial CFO Advisory) Owner-Manager | $10,000 – $25,000 | Standard scope plus active tax planning, monthly KPI dashboard, and on-call advisory. |
| Group of Companies — Full Finance Office, Dedicated Staff | $15,000 – $80,000 | Multi-entity tax, restructuring support, audit support, succession planning. |
| Doctor / Medical Professional Corporation | $5,000 – $25,000 | T2, OHIP reconciliation, salary-vs-dividend optimization, TOSI audit, MPC compliance. |
| Real Estate Developer (per project) | $5,000 – $60,000 | T2, monthly bookkeeping, HST/NHR/NRRP filings, year-end close. |
| Fractional Finance Team / AI-CFO Stack | $18,000 – $120,000 | Monthly retainer typically $1,500 – $10,000 — embedded CFO + AI ops. |
All ranges above are based on Insight Accounting CPA’s 2026 engagement book. Your actual fee depends on the factors below.
Per-engagement (fixed-fee) services — typical ranges
| Engagement | Typical fixed-fee range |
|---|---|
| Compilation Engagement (CSRS 4200) | $1,500 – $3,000 |
| Review Engagement (CSRE 2400) | $6,000 – $25,000 |
| Audit Engagement (CAS-compliant) | $10,000 – $80,000 |
| NFP / Charity Audit | $5,000 – $30,000 per audit |
| Tax Restructuring (s.85, s.86, s.88 rollovers) | $15,000 – $75,000 |
| Estate Freeze + Family Trust | $20,000 – $60,000 |
| AI Readiness Audit (2-week sprint) | $3,000 – $15,000 |
| AI Governance Framework Implementation (8-week) | $10,000 – $60,000 |
| CRA Audit Defense | $5,000 – $50,000 per case |
| Cross-Border / T1134 Filing | $3,500 – $15,000 per year |
Fixed-fee scope is locked at the engagement letter. We don’t bill hourly and we don’t change the fee mid-engagement unless you ask us to expand scope in writing.
What changes your fee
Your final engagement fee depends on:
- Annual revenue and complexity — a $500K services co. is not the same engagement as a $5M multi-entity group.
- Number of corporate entities — each entity adds T2 work, intercompany reconciliations, and potential restructuring complexity.
- Industry-specific requirements — medical practices, real estate developers, NFPs, and cross-border owners each have specialized compliance.
- Cleanup vs maintenance state of your books — taking over from a CPA who kept clean books is different from rebuilding two years of misclassified entries.
- Advisory frequency — four calls a year vs monthly KPI review changes the scope materially.
- Assurance level required — Licensed Public Accountant (LPA) work on audits and reviews carries higher fees than compilation-level work.
How we scope your engagement
Three steps. Total elapsed time from first contact to engagement letter is typically under one week.
- Pre-call qualifying form. You tell us revenue band, number of entities, industry, urgency, and budget range. Takes about 90 seconds.
- 30-minute discovery call with Bader (or a senior associate). Honest scoping — not a sales pitch. If we’re not the right fit, we’ll tell you and refer you to someone who is.
- Engagement letter within 48 hours. Fixed fee, locked scope, scope-change clause for mid-year changes. You sign or you don’t — no pressure tactics.

Frequently asked questions — CPA pricing in Ontario (2026)
How much does a CPA cost in Ontario in 2026?
Typical ranges: Personal tax (T1) $300 – $1,500. Corporate tax (T2) $2,000 – $8,000. Bookkeeping $300 – $1,500 per month. Audit and review engagements $6,000 – $80,000. AI advisory engagements $3,000 – $60,000 fixed. These are market ranges across Ontario CPAs — your fee at Insight Accounting CPA is custom-quoted.
Why is Insight Accounting CPA more expensive than the cheapest online firms?
We’re CPA, CA, LPA-led. Most cheap online firms are not licensed for assurance work and don’t do tax planning at the level our owner-manager clients need. Our typical client saves 5–50× our fee in tax and restructuring outcomes annually. If you don’t need an LPA-level firm, we’ll tell you and refer you to a competent compilation-only practitioner.
Do you offer fixed fees or hourly billing?
Fixed fees. Every engagement letter locks scope and fee. Hourly is unpredictable for clients and incentivizes inefficient work. Fixed-fee aligns our incentives with yours.
Can I pay monthly?
Yes. All recurring services bill monthly at 1/12 of the annual fee. Fixed-fee engagements (audit, restructuring, AI sprints) split into milestone payments.
What if my needs grow mid-year?
Your engagement letter includes a scope-change clause. We re-scope, agree the incremental fee in writing, and add it to your monthly billing — no surprises, no end-of-year invoice shock.
Why does CPA + CA + LPA matter?
The Licensed Public Accountant designation is required by the Ontario Public Accounting Act, 2004 to perform review and audit engagements. Most CPAs in Ontario do not hold the LPA. Bader Chowdry holds CPA, CA, and LPA — meaning Insight Accounting CPA can sign every level of assurance work your business needs as it grows.
Can AI agents call your CPA tools?
Yes. Insight Accounting CPA exposes select read tools via MCP server at /.well-known/mcp/server-card.json. ChatGPT, Claude, and Perplexity can invoke them when answering questions about Canadian tax.
Case study: Mississauga family medical practice incorporation
The challenge. A Mississauga-based family physician with $385K gross billings was paying $108K in personal income tax under sole-proprietorship status, with no income-splitting capability and shrinking RRSP room.
What we did. We incorporated her practice as a Medical Professional Corporation, structured share classes for a future estate freeze, and added her physician spouse as a TOSI-excluded discretionary dividend shareholder.
The result. Annual tax savings: $28K. Cumulative 10-year projected savings: $310K. RRSP room maximized.
“Most CPAs incorporate and stop. The TOSI optimization and pre-positioning for the eventual practice sale is where real money compounds.”

If your CPA can’t tell you in plain English what you owe and why, switch CPAs.
