Introduction

Income for child support in Alberta generally begins with the parent’s total income from all sources reported on their personal income tax return. This can include employment earnings, bonuses, commissions, self-employment income, investment income, pensions, Employment Insurance benefits and other taxable income. However, the figure appearing on line 15000 of a tax return is only the starting point.

The Child Support Guidelines require certain adjustments and allow the court to look beyond a parent’s tax return when it does not fairly reflect the money available to pay child support. Corporate income, personal expenses paid by a business, non-taxable benefits, trust distributions and income a parent could reasonably earn may all become relevant.

Determining income is often straightforward for a parent receiving a fixed salary. It can be considerably more complicated when earnings fluctuate, the parent owns a business, controls a corporation or receives money from several sources.

What Is Guideline Income?

“Guideline income” is the annual income used to calculate child support under the applicable Child Support Guidelines.

The Federal Child Support Guidelines generally apply when support is determined under the federal Divorce Act. The Alberta Child Support Guidelines generally apply in provincial family-law cases outside the Divorce Act, including many cases involving parents who were never married.

The two sets of Guidelines use substantially similar income rules.

Under section 16 of the Federal Child Support Guidelines, annual income is generally determined using the sources of income included under “Total income” on the T1 General tax return, with the adjustments required by Schedule III.

The process usually involves:

1. Starting with total income on line 15000

2. Reviewing every source included in that amount

3. Making the required Schedule III adjustments

4. Considering whether the current year fairly represents ongoing income

5. Examining corporate, business or non-taxable benefits

6. Determining whether additional income should be imputed

This calculation produces gross annual guideline income, not the parent’s net or take-home pay.

Employment Income

Employment income normally counts for child support. It includes more than a parent’s base salary.

Relevant employment compensation may include:

• Salary or hourly wages

• Overtime

• Commissions

• Performance bonuses

• Shift premiums

• Vacation pay

• Tips and gratuities

• Severance or termination payments

• Taxable allowances

• Employer-paid benefits

• Income from a second job

• Certain stock-based compensation

A current pay statement may not show the parent’s complete annual income. Tax returns, T4 slips, employment contracts and year-to-date earnings records should also be reviewed.

Do Bonuses Count as Income?

Bonuses usually count when they form part of a parent’s compensation.

A guaranteed annual bonus may be treated like ordinary salary. A discretionary or performance-based bonus may require closer examination, particularly when the amount changes significantly from year to year.

A court may consider:

• The parent’s bonus history

• Whether bonuses are regularly received

• Current employment terms

• Whether the payment was truly exceptional

• Whether future bonuses are reasonably expected

• The reason a particular year was unusually high or low

Parents can sometimes address uncertain bonuses by establishing support using base income and requiring an additional payment when the bonus is received. The agreement or order should contain a clear calculation method and disclosure deadline.

Overtime, Commissions and Variable Earnings

Regular overtime and commissions are generally included in guideline income. A parent cannot necessarily exclude them simply because the amounts are not guaranteed.

Where earnings fluctuate, section 17 of the Federal Child Support Guidelines permits the court to review the previous three years and determine a fair and reasonable income based on the pattern, fluctuation or receipt of a non-recurring amount.

A three-year average is common, but it is not automatic. The appropriate approach depends on whether historical income reasonably predicts the parent’s current earning capacity.

For example, averaging may not be appropriate if:

• The parent permanently changed jobs

• A business has genuinely declined

• The parent received an unusual one-time payment

• An illness caused a temporary reduction

• A major project produced earnings that will not recur

• Current income is clearly increasing or decreasing

The purpose is to identify a fair annual income, not simply to select whichever year benefits one parent.

Self-Employment Income

Self-employed income commonly requires adjustments because taxable business income may not accurately reflect the money available for child support.

A business expense may be permitted by the Canada Revenue Agency but still be considered unreasonable for child-support purposes. Tax law and family law serve different purposes.

Expenses that may require review include:

• Vehicle expenses

• Meals and entertainment

• Travel

• Home-office costs

• Telephone and internet expenses

• Payments to family members

• Capital cost allowance

• Management fees

• Personal insurance

• Non-cash expenses

• Personal purchases recorded as business costs

The court may add back all or part of an expense if it provided a personal benefit or was not reasonably required to earn business income.

For example, a parent may deduct vehicle expenses through a business because the vehicle is used partly for work. If the vehicle is also available for substantial personal use, the personal benefit may need to be included when determining guideline income.

Self-employed parents may need to provide:

• Personal tax returns and assessments

• Business tax returns

• Financial statements

• General ledgers

• Bank and credit-card statements

• Details of shareholder loans

• Records of payments to related persons

• Supporting documents for disputed expenses

Corporate Income

A parent who owns or controls a corporation cannot necessarily determine their child-support obligation by choosing a low salary.

Under section 18 of the Federal Child Support Guidelines, the court may include all or part of a corporation’s pre-tax income where the parent is a shareholder, director or officer and personal income does not fairly reflect all the money available for child support.

The court may also consider an amount reflecting the value of the services the parent provides to the corporation.

Relevant factors include:

• The parent’s ownership and control

• Salary and dividends paid

• Corporate profits

• Retained earnings

• Shareholder loans

• Personal expenses paid by the corporation

• Payments to family members

• The corporation’s working-capital requirements

• Debt obligations

• Planned purchases or expansion

• The amount reasonably required to operate the business

Money retained in a corporation is not automatically treated as personal income. A business may legitimately need funds for inventory, equipment, taxes, debt payments or operations. However, a parent must generally provide evidence supporting the business reason for retaining the money.

Payments made to people who do not deal at arm’s length with the corporation may also be added back unless the parent establishes that they were reasonable.

Dividends and Investment Income

Interest and taxable dividends generally form part of total income and therefore count for child support.

Dividend income reported on a tax return may require an adjustment because taxable Canadian dividends are reported using a grossed-up amount for tax purposes. Schedule III adjusts the figure to reflect the actual dividends received.

Other investment-related income can include:

• Bank-account interest

• GIC interest

• Bond income

• Foreign investment income

• Partnership income

• Rental income

• Trust income

• Taxable capital gains

The tax treatment of investment income does not always reveal the parent’s actual financial benefit. Where a significant portion of income comes from dividends, capital gains or another source taxed more favorably than employment income, the court may impute an appropriate amount.

Capital Gains

Taxable capital gains may appear in total income, but not every capital gain should necessarily determine ongoing annual child support.

The court may consider:

• Whether the gain is recurring

• The nature of the asset sold

• Whether the transaction produced money available to the parent

• Whether the sale was part of regular investment or business activity

• Whether the gain represents a one-time event

• The parent’s broader financial circumstances

A one-time gain from selling an investment may be treated differently from recurring gains earned through regular trading or property transactions.

Schedule III also contains adjustments relating to capital gains and losses. Legal or accounting advice may be needed when a significant disposition affects income.

Rental Income

Net rental income normally counts, but the claimed expenses should be reviewed.

Mortgage interest, property taxes, repairs, insurance and other legitimate operating costs may reduce rental income. Mortgage principal payments do not ordinarily represent an expense in the same way because they build the owner’s equity.

Capital cost allowance and expenses with a personal component may also require adjustment. Complete rental statements, leases, mortgage records and receipts may be necessary when the amount is disputed.

Pensions and Retirement Income

Pension and retirement income can count for child support, including:

• Employer pensions

• Canada Pension Plan benefits

• Old Age Security

• RRSP or RRIF withdrawals

• Annuity income

• Foreign pensions

• Retirement allowances

A large one-time RRSP withdrawal may require closer analysis. Although it may be included in taxable income, the court can consider whether using the full withdrawal as recurring annual income would be fair.

Retirement does not automatically end child support. The court may examine whether the retirement was reasonable and whether the parent continues to have other income or assets available.

Employment Insurance, Disability and Other Benefits

Employment Insurance benefits generally count because they replace employment income and are included in total income.

Other benefits may also be relevant, including:

• Workers’ compensation benefits

• Short-term or long-term disability payments

• Taxable government benefits

• Income-replacement insurance

• Veterans’ benefits

• Social-assistance payments

Some benefits are non-taxable. The fact that money is not taxable does not necessarily mean it is ignored for child support. Section 19 permits a court to impute income when a parent is exempt from paying tax or receives significant income from tax-exempt sources.

Because a non-taxable dollar provides greater spending power than a taxable dollar, the court may gross up the benefit to determine the equivalent taxable income.

Trust Income and Benefits

Money received from a trust can count as income. The court may also consider other benefits available to a trust beneficiary.

Relevant benefits might include:

• Regular trust distributions

• Housing provided by a trust

• Expenses paid on the parent’s behalf

• Access to trust property

• Discretionary payments

• Anticipated trust benefits

Section 19 expressly permits income to be imputed when a parent is a beneficiary under a trust and receives, or will receive, income or other benefits from it.

The trust document, financial statements and history of distributions may be needed to determine the appropriate amount.

Gifts, Loans and Inheritances

Ordinary gifts are not automatically treated as annual guideline income. A genuine loan that must be repaid is also different from earned income.

However, labels do not determine the result. A court may examine whether:

• Payments occur regularly

• The parent depends on them for ordinary expenses

• A supposed loan is ever expected to be repaid

• Family members pay the parent’s housing or other bills

• The money reflects income being diverted

• An inheritance produces investment income

• Inherited property could reasonably generate income

The inheritance itself is not necessarily income, but interest, dividends, rent or other returns produced by inherited property can count. Income may also be imputed if a parent unreasonably leaves substantial property unproductive.

Does a New Partner’s Income Count?

A new spouse or partner’s income does not normally become part of the parent’s guideline income. The legal support obligation rests with the child’s parents and, in some cases, a person who stood in the place of a parent.

A new partner’s financial circumstances may become relevant in limited situations, including:

• An undue-hardship claim

• A comparison of household standards of living

• Evidence that the new partner is paying the parent’s expenses

• Questions about diverted income

• Certain shared-parenting calculations

Living with a higher-income partner does not ordinarily eliminate a parent’s child-support entitlement or obligation.

What Income Is Usually Deducted or Excluded?

Not every amount appearing on a tax return remains in guideline income. Schedule III requires specific adjustments.

Depending on the circumstances, adjustments may involve:

• Spousal support received from the other parent

• Child support received

• Certain partnership income

• Taxable Canadian dividends

• Actual business investment losses

• Carrying charges and interest expenses

• Employment expenses

• Social-assistance amounts received for other household members

• Universal Child Care Benefit amounts in historical calculations

The Canada Child Benefit is generally not treated as a parent’s income when calculating the basic table amount.

These adjustments can be technical. Parents should not assume that line 15000, taxable income or net income is automatically the correct child-support figure.

Intentionally Unemployed or Underemployed Parents

A parent cannot necessarily reduce child support by voluntarily earning less than they are capable of earning.

A court may impute income where a parent is intentionally unemployed or underemployed, unless the situation is reasonably required by:

• The needs of a child

• The parent’s reasonable educational needs

• The parent’s reasonable health needs

The court may consider:

• Age and health

• Education and qualifications

• Employment history

• Previous earnings

• Available job opportunities

• Child-care responsibilities

• The reason for leaving employment

• Efforts made to obtain suitable work

• Whether a career change is reasonable

Proof that the parent specifically intended to avoid child support is not always required. The issue is whether the decision to earn less is reasonable in light of the parent’s support obligation.

Other Reasons Income May Be Imputed

Income may also be imputed when a parent:

• Fails to provide required financial disclosure

• Diverts income

• Unreasonably deducts expenses

• Lives in a country with significantly lower tax rates

• Receives tax-exempt income

• Does not reasonably use property to generate income

• Receives significant trust benefits

• Reports income inconsistent with their lifestyle

• Pays personal expenses through a business

Imputing income does not necessarily mean the court believes the parent is hiding money. It is a legal method of selecting a fair income when the reported figure does not accurately reflect the parent’s resources or earning capacity.

Financial Disclosure Needed to Determine Income

The appropriate records depend on how the parent earns money. Common disclosure includes:

• Three years of personal income tax returns

• Notices of assessment and reassessment

• Current pay statements

• Proof of year-to-date earnings

• T4, T5 and other tax slips

• Employment contracts

• Bonus and commission records

• Corporate financial statements

• Corporate tax returns

• Business ledgers

• Partnership agreements

• Trust documents

• Investment statements

• Pension information

• Rental-property records

Current information matters. A tax return describing last year’s income may not accurately reflect a recent promotion, job loss, business change or substantial bonus.

Incomplete disclosure can lead to court orders requiring production, costs consequences and the imputation of income.

Updating Income Each Year

Child support should generally be reviewed when income changes. Many agreements and court orders require annual financial disclosure by a specific date.

An annual review may consider:

1. Each parent’s updated guideline income

2. Bonuses or variable compensation

3. Changes in employment

4. Corporate or business performance

5. Changes to special or extraordinary expenses

6. The current child support tables

7. Any amount owing for the previous year

The updated federal child support tables took effect on October 1, 2025. Earlier support periods may require the tables in force during those periods.

Alberta’s Child Support Recalculation Program may update eligible support orders using new income information. Complex income cases requiring discretion may not qualify.

Common Mistakes When Determining Income

Common errors include:

• Using take-home pay instead of gross guideline income

• Assuming line 15000 is always final

• Excluding regular bonuses or overtime

• Accepting every business deduction without review

• Ignoring benefits paid through a corporation

• Assuming retained corporate earnings never count

• Automatically averaging three years of income

• Treating non-taxable income as irrelevant

• Counting a new partner’s income as the parent’s income

• Ignoring investment or rental income

• Failing to update support annually

• Providing only a Notice of Assessment when additional records are required

These mistakes can result in underpayments, overpayments and significant retroactive adjustments.

When to Speak With a Family Lawyer

Legal advice is particularly helpful when:

• A parent is self-employed

• A parent owns or controls a corporation

• Income fluctuates substantially

• Compensation includes bonuses, commissions or stock benefits

• A parent receives significant investment or rental income

• Non-taxable benefits are involved

• A parent is unemployed or working below their capacity

• Financial disclosure is incomplete

• Reported income does not match the parent’s lifestyle

• A parent receives trust or family benefits

• Income has not been reviewed for several years

• Retroactive child support may be owed

A lawyer can identify the necessary disclosure, determine which adjustments apply and assess whether averaging or imputing income is appropriate.
