Private Tax Risk Advisory · Mississauga
High-Stakes Tax Risk Advisor for Canadian Business Owners, Real Estate Groups, and Private Companies
Muib Khan advises owners, families, real estate groups, cash-heavy businesses, and private companies facing significant CRA exposure, HST/GST complexity, business sale tax risk, and multi-entity wealth decisions.
When the numbers are large, routine tax advice stops being enough. The questions become questions of judgment: what to document, what to disclose, in what order, and who needs to be at the table before a decision hardens.
CRA risk does not stay inside a tax return. It reaches cash flow, enterprise value, financing, transactions in progress, and family wealth. The work here is to see that exposure clearly — and manage it deliberately.
Private consultations available by request. Call (438) 953-4465.
When Tax Risk Becomes Business Risk
Owners rarely reach out about a tax return. They reach out when a tax issue starts behaving like a business problem:
- Significant CRA audit or reassessment exposure
- HST/GST audits, denied input tax credits, and documentation gaps
- Payroll, subcontractor, and cash transaction risk
- Tax concerns inside a business sale or acquisition
- Real estate development, assignment, sale, and refinancing tax issues
- Multi-entity corporate and family structures
- Owner wealth extraction and tax governance
- Coordination with tax lawyers, M&A advisors, bankers, lenders, and wealth teams
Every one of these is more manageable early. Options narrow as deadlines pass and positions harden.
Advisory Mandates
Engagements are structured as defined mandates — clear scope, clear deliverables, a clear end state. Seven patterns cover most of what arrives at this desk.
- 01
CRA Crisis Advisory
When a CRA audit, net worth assessment, or reassessment is underway, sequence and discipline matter as much as argument. I organize the facts, quantify the exposure, manage what is said and produced, and coordinate tax counsel where needed. A Notice of Reassessment starts a 90-day objection clock from its mailing date — the earlier the file is structured, the more options remain.
- 02
HST/GST Audit & Exposure Advisory
HST/GST is where documentation problems quietly become assessments. Denied input tax credits, mismatches between corporate tax and GST/HST filings, and assignment-sale exposure can build for years before CRA raises them. I assess the true exposure, strengthen the documentation position where the rules allow, and advise through HST/GST audits, assessments, and objections.
- 03
Pre-Exit Tax Risk & Wealth Protection
Buyers price tax risk. Unremitted HST, shareholder loan balances, and structure defects surface in due diligence and reprice or unwind deals. Ideally beginning 24 months before a sale, I work through qualification for the lifetime capital gains exemption — $1.25 million for qualifying small business corporation shares, indexed from 2026 — purification, and the exposures a buyer's diligence team will look for, before they look.
- 04
Family Enterprise Tax Governance
Estate freezes, family trusts, the 21-year deemed disposition, transfers between generations — family wealth decisions carry tax consequences that arrive years after the decision is made. I act as a standing tax governance advisor to the family enterprise: mapping the structure, tracking the deadlines, and coordinating with counsel so each decision is documented and defensible.
- 05
Real Estate Tax Risk Advisory
CRA operates a dedicated real estate compliance program, and the GTA sits squarely inside it. Property flipping reassessments under the 365-day rule, HST on assignment sales, denied new housing rebates, and principal residence challenges are now routine. I advise developers, builders, and investor groups on the tax character of each project before filing positions harden into exposure.
- 06
Cash-Heavy Business Tax Risk Advisory
CRA audits cash-intensive businesses differently — through bank deposit analysis, industry benchmarks, and net worth methods, not the books alone. I help owners build documentation and governance that stand up to indirect verification, and advise when a CRA audit is already underway. The work is professional and factual: organizing what is real, never concealing it.
- 07
Private Company Tax Office
Most private companies cannot justify an internal tax department, yet face tax decisions every month: shareholder remuneration, inter-entity transactions, CRA correspondence, planning deadlines. This mandate is a standing private tax office for owner-managed companies — a senior advisor who already knows the structure before the question arrives.
Advisory for Industries Where Tax Risk Can Escalate Quickly
In these industries, documentation gaps become exposure quickly. CRA applies industry benchmarks, third-party data, and indirect verification methods by default — so ordinary record-keeping problems can read, on paper, as something they are not.
- Real estate developers and investors
- Construction and renovation
- Restaurants, franchises, lounges, and hospitality
- Trucking and logistics
- Medical, dental, and professional corporations
- Automotive dealerships, repair, and leasing
- Jewelry and luxury retail
- Convenience stores, gas stations, and multi-location retail
- Staffing agencies and subcontractor-heavy businesses
- E-commerce and online sellers
- Import, export, and wholesale trade
- Private lenders and mortgage businesses
- Family-owned operating companies
- High-net-worth owner-managed businesses
The approach here is professional, not judgmental: establish the facts, quantify the exposure, and deal with it deliberately.
The advisor
Senior tax risk counsel, handled personally
I am Muib Khan, 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 decisions that surround a business sale, a real estate portfolio, or a family structure.
Every engagement is handled personally, from the first confidential conversation onward. The work is steady and plain-spoken: see the exposure clearly, quantify it honestly, and prepare decision options so ownership decides deliberately, with the full picture in front of them.

The Role
This practice does not replace legal counsel, investment advisors, bankers, or an internal finance team. Each holds a seat for a reason, and the work is strongest when they are all at the table.
The role is senior strategic tax risk advisor: organizing the facts, clarifying the exposure in plain terms, coordinating the professionals involved, and preparing decision options — so that ownership decides deliberately, with the full picture in front of them.
How Private Mandates Work
Every engagement follows the same quiet sequence.
- 01
Confidential Consultation
A private conversation about the situation — what has happened, what is at stake, and what the timeline demands. No documents are required at this stage.
- 02
Strategic Assessment
A structured review of the relevant facts, filings, and structures. The output is a clear picture: where the exposure sits, how large it plausibly is, and which decisions cannot wait.
- 03
Advisory Mandate
A defined engagement with a defined scope — a CRA matter, a transaction, a restructuring, or a standing advisory role — confirmed in an engagement letter before work begins.
- 04
Ongoing Governance
For families and companies with continuing complexity: periodic risk review, documentation discipline, deadline tracking, and a senior advisor who already knows the file when something moves.
Who This Is For
- Business owners facing significant CRA audit or reassessment exposure
- Real estate developers, builders, and investor groups
- Owners preparing to sell, restructure, or refinance a business
- Families with multi-entity structures, trusts, or succession decisions ahead
- Cash-intensive businesses ready to put documentation and governance in order
- Private companies that need senior tax judgment without building a tax department
- Lawyers, M&A advisors, bankers, and wealth teams seeking tax risk support on a client file
Who This Is Not For
- Basic personal or corporate tax return preparation
- Routine bookkeeping and payroll processing
- Low-complexity personal tax situations
- One-time, filing-only engagements
- Aggressive schemes or structures designed to defeat the rules
- Anyone seeking guaranteed outcomes — no honest advisor promises results
- Anyone looking to hide income — that conversation ends before it begins
Routine work deserves a conventional accounting relationship. These mandates exist for matters where the stakes justify senior attention.
For High-Stakes Tax Matters, Start Privately.
Significant tax decisions deserve a considered, confidential conversation — not a call centre. Consultations are private, selective, and personally handled. If the matter is already moving — a CRA audit letter, a reassessment, a transaction timeline — reach out sooner rather than later. Options narrow as deadlines pass.
Private consultations available by request. Call (438) 953-4465. Personally answered — typically within business hours.
