Your Ex Is Self-Employed. Here Is How to Get Honest Financial Disclosure.
When support is calculated from a paycheque, income is easy to prove. When your former partner owns the business that pays them, income becomes whatever their accountant says it is. Suddenly the company that supported your household “loses money,” and the support cheque shrinks to match.
Family courts in Ontario have seen this movie many times, and the law has answers. This guide walks through what a self-employed payor must disclose, the red flags that reveal hidden income, and what to do when the numbers still do not add up, including the complicated question of expert reports.
Why self-employed income is different
An employee’s income for support is usually just the total income line on their tax return. A business owner controls both sides of that number. They decide what the business pays them, what it deducts as expenses, and what stays inside the company. The Income Tax Act lets them deduct legitimate business expenses, but many of those deductions, such as a vehicle, a phone, travel, or a home office, also carry a personal benefit. A person can be living comfortably on money that never appears in their personal income at all.
That is why the law does two important things. First, it demands more disclosure from the self-employed. Second, it puts the burden on them to justify their numbers.
A self-employed person must prove the basis of their own net income. If they deduct expenses, the onus is on them to explain why those deductions did not personally benefit them and should reduce their income for support. Courts have applied this principle even where the income flows through a corporation the person fully controls. You are not being difficult by asking. They are obligated to answer.
What the rules require them to hand over
In an Ontario support case, both parties complete a sworn Financial Statement. But for a self-employed party, the Federal Child Support Guidelines require more. Section 21 obligates them to produce, for the three most recent taxation years:
- Personal income tax returns, with every schedule and attachment
- Every Notice of Assessment and reassessment
- The financial statements of their business or professional practice
- A breakdown of all salaries, wages, management fees, or other payments made to people or companies the payor does not deal with at arm’s length
That last item is the one people miss, and it is often where the money is. Salaries paid to a new partner, a sibling on the payroll, or management fees paid to a numbered company all belong on the table.
- Personal T1 returns and Notices of Assessment, three years
- Business or corporate financial statements, three years, including income statement and balance sheet
- Corporate T2 returns if the business is incorporated
- The general ledger or a detailed expense listing
- Business bank account and business credit card statements
- HST returns and remittances
- Statements of any shareholder loan account
- Loan, mortgage, or credit applications made by the payor or the business
- The breakdown of all non-arm’s-length payments required by s. 21
A note on loan applications: they are quietly one of the most revealing documents in these cases. People who minimize income to the court and to the CRA often maximize it when they want a bank to lend them money. When the mortgage application says one number and the Financial Statement says another, the credibility battle is usually over.
Red flags that income is being hidden
- Lifestyle does not match declared income. New truck, vacations, renovations, on paper poverty. Courts notice, and spending patterns are evidence.
- Revenue collapses right after separation. A business that thrived during the relationship suddenly cannot pay its owner.
- Continuous business losses. No rational person runs a money-losing business for years. Courts may ask why it has not been fixed or closed.
- Personal expenses run through the business. Groceries, clothing, personal travel, the family cell phones, a personal credit card paid by the company.
- Cash-heavy operations. Some businesses receive far more cash than their returns suggest. How customers pay matters.
- One bank account for everything. Blending personal and business banking makes honest accounting nearly impossible, and that is sometimes the point.
How courts fix the number: imputing income
Where disclosure is inadequate or deductions are unreasonable, section 19 of the Guidelines lets the court impute income. Common triggers include:
- Failing to provide required income information
- Unreasonably deducting expenses from income
- Being intentionally under-employed or unemployed
- Owning property that is not reasonably used to generate income
Even a legitimate expense can be added back into income if it is out of proportion to the business. Vehicle costs for someone who works from home, generous meals and entertainment, capital cost allowance on assets that hold their value, and salaries to family members are the classic examples. And in serious cases involving a corporation, courts can go further and treat the company’s pre-tax profit as available for support, not just the salary the owner chose to pay themselves.
The expert report question
When the paper trail is complicated, an income determination report from a CBV or forensic accountant can settle what a payor truly earns. These reports are powerful, but they come with complications worth understanding before you commit:
- Cost and proportionality. A full report can run from several thousand dollars to well beyond, and the court expects the expense to be proportionate to what is actually in dispute. For modest support differences, aggressive document requests and cross-examination may achieve more per dollar.
- Garbage in, garbage out. An expert can only analyze what is disclosed. If your ex is stonewalling, the disclosure fight comes first. An expert report built on incomplete records can even lend false credibility to bad numbers.
- One expert or two. Parties can jointly retain a neutral expert, which is cheaper and often persuasive, or each retain their own, which can descend into a battle of experts. The right choice depends on trust, budget, and how far apart the positions are.
- Timing. Reports take months. If support needs to be fixed now, courts can set a temporary number and adjust later once the report lands.
What you can do right now
- Write down what you know. You lived with this business. How customers paid, what ran through the company, what the lifestyle really was. Your knowledge shapes the whole disclosure strategy.
- Gather what you already have. Old tax returns, statements, loan documents from the relationship are all fair evidence.
- Make disclosure demands early and in writing. A documented trail of ignored requests becomes the foundation for a motion to compel disclosure, with costs consequences for the stonewaller.
- Do not settle blind. A support agreement built on unverified numbers can shortchange your children for years. Getting the income right the first time is nearly always cheaper than fixing it later.
