PROFESSIONAL DOSSIER
About Muib Khan
Canadian tax and advisory professional in Mississauga, Ontario — advisor to business owners, real estate groups, family enterprises, and private companies on high-stakes tax risk.
I am a Canadian tax and advisory professional based in Mississauga, Ontario. My practice is focused on high-stakes tax risk: CRA audit matters, HST/GST exposure, and the strategic tax decisions that surround a business sale, a real estate portfolio, a family structure, or a growing private company.
Most of my work is with owner-managed businesses — companies where the corporate tax file and the family's wealth are, in practice, the same file. Business owners, real estate developers and investor groups, family enterprises, and private companies across Mississauga, the Greater Toronto Area, and Ontario bring me matters where the numbers are large enough that judgment matters as much as technical accuracy.
A significant part of that experience sits in cash-intensive and high-value industries — restaurants and hospitality, construction, trucking and logistics, automotive, jewelry and luxury retail, convenience and multi-location retail — where CRA applies indirect verification methods such as bank deposit analysis, industry benchmarks, and net worth assessments. In those industries, ordinary record-keeping gaps can look, on paper, like unreported income. Much of my work is helping owners establish what is real and present it properly.
I approach tax as a risk discipline rather than a filing exercise. The questions that decide outcomes are rarely on the return itself: what to document, what to disclose, in what order, and who needs to be at the table before a position hardens. My role is to see the exposure clearly, quantify it honestly, and prepare decision options in plain language — so ownership decides deliberately, with the full picture in front of them.
Complex matters are rarely resolved by one professional. I am not a lawyer and do not provide legal representation; where privilege or litigation is in play, tax counsel takes that seat and I support it — organizing the facts, preparing the analysis, and keeping the numbers coherent across the whole advisory table of lawyers, M&A advisors, bankers, lenders, and wealth teams.

Background & Credentials
The designations behind the practice are granted and governed by two professional bodies — CPA Ontario in Canada, and the Association of Chartered Certified Accountants in the United Kingdom.
- Chartered Professional Accountant (CPA) — granted and regulated by CPA Ontario
- Certified General Accountant (CGA) — legacy Ontario designation, now governed by CPA Ontario
- Fellow of the Association of Chartered Certified Accountants (United Kingdom) — fellowship follows sustained membership in good standing
- Canadian tax focus — CRA audit matters, HST/GST exposure, and strategic tax advisory for owner-managed and private companies
- Based in Mississauga, Ontario — serving the Greater Toronto Area, Ontario, and clients across Canada
Both bodies bind their members to codes of professional conduct, including confidentiality obligations that apply to every matter this practice touches.
What I Focus On
Seven mandate patterns cover most of what arrives at this desk. Each has its own page; together they share one thread — tax risk significant enough to affect the business itself, not just the return.
- CRA audit and reassessment matters — tax audits, net worth assessments, objections, and the 90-day windows that govern them
- HST/GST exposure — HST/GST audits, denied input tax credits, documentation discipline, and assignment-sale issues
- Pre-exit tax risk — preparing a business and its structure before a sale, ideally 24 months out
- Real estate tax risk — property flipping reassessments, HST on assignments, new housing rebates, and principal residence challenges
- Cash-heavy business tax risk — documentation and governance that stand up to indirect verification
- Family enterprise tax governance — estate freezes, family trusts, the 21-year deemed disposition, and succession
- A standing private tax office for owner-managed companies that need senior tax judgment without an internal tax department
When a matter falls outside these patterns, I say so early — and, where I can, point to the right professional for it.
Method
How I Work
Four working principles run through every mandate.
- 01
Defined Mandates
Engagements are selective and structured: a private consultation, a strategic assessment, then a defined mandate confirmed in an engagement letter before work begins. Scope is explicit — what I am doing, what I am not, and when the mandate ends.
- 02
Confidentiality as Discipline
Matters are handled discreetly, and professional conduct rules bind me to confidentiality. I am equally direct about the limit: communications with an accountant are generally not privileged in Canada, so where privilege matters, the file is structured with tax counsel from the start.
- 03
Coordination With Counsel and Advisors
I am not a lawyer and do not provide legal representation. I work alongside tax lawyers, M&A advisors, bankers, lenders, and wealth teams — organizing the facts, quantifying the exposure, and preparing the analysis the table needs. The work is strongest when each professional holds their own seat.
- 04
Plain Language, Quantified
Every exposure is explained in plain terms and, wherever possible, in numbers: what is at risk, how large it plausibly is, by when it must be addressed, and what each option costs. Calm is a method — decisions made in panic are the expensive ones.
Who I Do Not Act For
A selective practice has to be clear about its edges. I do not take on:
- Routine personal or corporate tax return preparation, bookkeeping, or payroll
- Low-complexity matters that a conventional accounting relationship serves well
- Aggressive schemes or structures designed to defeat the rules
- Anyone seeking a guaranteed outcome — no honest advisor can promise one
- Anyone looking to hide income from CRA — that conversation ends before it begins
Declining the wrong mandate is part of protecting the right ones.
Co-counsel and referrals
For Professional Advisors
A meaningful share of this practice arrives by referral from lawyers, M&A advisors, bankers, and wealth teams who need senior tax analysis on a client file without giving up the relationship. That boundary is a working rule: your client remains your client, and engagement confidentiality covers the file, the findings, and the fact of the referral itself.
The private consultation form is the referral channel of record — WhatsApp is often not an option on corporate devices. Support on a professional file typically takes one of these shapes:
- Co-counsel support on CRA disputes — organizing the record, quantifying exposure, and preparing schedules and working papers under counsel's direction
- Independent analysis of tax positions, filings, and CRA correspondence when a file needs a second, unaffiliated read
- Deal support for M&A advisors and lenders — sell-side exposure review before diligence, and quantification of the tax findings that surface during it
- Net-worth-assessment methodology rebuttal for tax litigators — a line-by-line challenge of CRA's schedules, deposit analysis, and assumptions
- Engagement confidentiality throughout — referral relationships and client files are handled discreetly, with scope confirmed in writing before work begins
Start the Conversation Privately.
If the matter on your desk involves significant CRA exposure, HST/GST complexity, a transaction, or a family structure, a considered conversation is the right first step. Consultations are private, selective, and personally handled. Describe the situation in broad terms — confidential details can wait until an engagement is in place.
Private consultations available by request. WhatsApp: +1-647-510-8878. Personally answered — typically within business hours.
