10 Reasons Your Child Support Amount is Wrong (And How to Fix It with the 2026 Table Updates)

Child support is not a "set it & forget it" obligation. If your support order was signed more than a year ago, there is a high probability that the number on that paper is legally incorrect. In Ontario, child support is governed by strict tables and federal guidelines that fluctuate based on economic data.

As we move into 2026, the landscape has shifted. The Canadian government recently updated the Federal Child Support Tables, and if you are still paying or receiving based on 2017 or 2021 data, you are likely operating under the wrong legal standard. Whether you are a payor in Brampton or a recipient in Orangeville, accuracy is your right.

1. YOU ARE USING OUTDATED TABLES

The most common reason a child support amount is wrong is simply the passage of time. The 2025 Federal Child Support Tables introduced significant changes that carry into 2026. These tables are adjusted to reflect current tax rates and the cost of living. If your order relies on the 2017 tables, you are using a mathematical relic.

2. THE NEW INCOME THRESHOLD SHIFT

The 2026 updates have raised the floor for child support. Previously, the income threshold where support obligations began sat around $13,000 annually. Under the new 2026 standards, this has increased to $16,000. For low-income earners in Brampton, this shift could mean the difference between owing support & meeting basic self-support needs.

3. SECTION 7 EXPENSES ARE MISSING

Table support is just the baseline. "Special & Extraordinary Expenses": known as Section 7 expenses: often go uncalculated. These include:

• Childcare costs.

• Medical & dental insurance premiums.

• Extraordinary expenses for extracurricular activities (e.g., competitive hockey or dance).

• Post-secondary education tuition.

If these aren't shared proportionately to your respective incomes, the total support amount is fundamentally wrong. Learn more in our Child Support 101 Guide.

4. INTENTIONAL UNDEREMPLOYMENT

Is the payor suddenly working fewer hours? Did they quit a high-paying job to "start a business" that earns nothing? A Brampton Family Lawyer can ask the court to "impute" income. This means the court treats the person as if they are earning what they should be earning based on their skills & education, rather than what they claim to earn. We don’t let people hide behind unemployment to avoid their responsibilities.

5. HIGH-INCOME EARNER COMPLEXITIES

Once a payor’s income exceeds $150,000, the standard table rules become more flexible. The court has the discretion to deviate from the table if the amount is deemed "inappropriate." High-income cases in Peel Region require a sophisticated analysis of the child's actual needs & the family's standard of living before the split.

6. SHARED PARENTING & THE 40% RULE

If a child spends at least 40% of their time with each parent, the "straight table" amount usually doesn't apply. Instead, the court looks at a "set-off" amount: the difference between what each parent would pay the other. If your parenting schedule has changed since your last court order, your support amount is almost certainly incorrect.

7. INCORRECT SELF-EMPLOYED INCOME

Calculating income for a business owner is difficult. Many payors try to deduct personal expenses through their corporations to lower their "Line 15000" income. However, family law courts look at "grossed-up" income. What the CRA considers a valid business deduction, a Child Custody Lawyer Brampton might successfully argue is actually income available for support.

8. POST-SECONDARY EDUCATION UPDATES

Does your order state that support ends at 18? In Ontario, that is not always the case. If a child is enrolled in a full-time program of study, support usually continues. Many parents in Brampton stop paying at 18 without realizing they are accruing massive arrears. Conversely, many recipients fail to ask for the necessary contributions toward tuition & residence. See our guide on when child support ends.

9. CHANGES IN RESIDENCE

If a child has moved from one parent's home to the other, the support must flip immediately. We see many cases where a payor continues to pay even after the child has moved in with them, simply because they haven't updated the court order. You cannot get that money back easily once it’s spent.

10. FAILURE TO DISCLOSE ANNUAL INCOME

Most separation agreements require an annual exchange of Income Tax Returns & Notices of Assessment. If you haven't seen the other parent’s NOA in two years, you have no way of knowing if the support amount is accurate. Income fluctuates; support must follow.

HOW TO FIX IT: THE 2026 ROADMAP

If you suspect your child support amount is wrong, you cannot simply change the payment yourself. That leads to FRO (Family Responsibility Office) enforcement, frozen driver’s licenses, & garnished wages.

STEP 1: CALCULATE THE NEW TOTAL

Use the 2026 table updates to find the "presumptive" amount. Our team at OMNI LAW GROUP uses professional software to run these calculations with precision, accounting for taxes, benefits, & Section 7 variables.

STEP 2: REQUEST DISCLOSURE

You are legally entitled to see the other parent’s financial information. If they refuse, a Brampton Family Lawyer can file a Motion to compel that disclosure.

STEP 3: THE MATERIAL CHANGE IN CIRCUMSTANCES

To change a final order, you must prove a "material change." The 2026 table updates, combined with a change in income or parenting time, usually meet this threshold.

STEP 4: CONSENT OR LITIGATION

If both parents agree the amount should change, we can draft a Consent Order. This is the fastest & most cost-effective way to fix the problem. If they don't agree, we are prepared to advocate for you at the A. Grenville & William Davis Courthouse in Brampton or the Orangeville Courthouse.
