How to file taxes for the first time as a family

Filing an income tax return for the first time can feel complicated, especially when several family members have different sources of income and expenses. The process becomes easier when you collect documents early, understand the main credits, and keep personal information consistent across every form.

In Canada, most people file through the Canada Revenue Agency (CRA). A tax return reports income, claims deductions and credits, and determines whether your household receives a refund, owes tax, or qualifies for income-tested benefits.

Families should usually file every year, even when income was low or no tax is owing. A return may be needed to calculate the Canada Child Benefit, GST/HST credit, provincial benefits, and other support payments.

Gather your family’s tax documents

Start by collecting a separate folder for each adult in the household. Common documents include T4 slips from employers, T4A slips for pensions or other benefits, T5 slips for investment income, and records of employment insurance or social assistance payments. Self-employed workers should gather invoices, business expenses, and mileage records.

You may also need receipts for childcare, medical expenses, charitable donations, tuition, moving costs, union dues, professional fees, and RRSP contributions. Online CRA accounts often contain copies of slips submitted by employers and financial institutions, but checking the original documents helps identify missing information.

Each family member needs a valid Social Insurance Number. Keep names, birth dates, marital status, and addresses accurate. If you have a spouse or common-law partner, both returns should generally be prepared together because several credits and benefit calculations use combined family income.

Choose a filing method

Most first-time filers use CRA-certified tax software. Free options may be available for people with straightforward returns, while paid software can provide additional guidance for self-employment, rental income, investments, or multiple provincial forms. NETFILE allows eligible taxpayers to send returns electronically.

A paper return is another option, although processing may take longer. If your household situation is complex, a tax professional can help with business income, foreign assets, separation, disability claims, or a recent move to Canada. Before paying for assistance, check what services are included and whether the preparer will support corrections later.

Your tax return contains sensitive financial information. Review the website’s privacy policy before sharing personal details online, and use secure accounts rather than sending a Social Insurance Number through ordinary email.

Understand family credits and benefits

Tax deductions reduce taxable income, while non-refundable and refundable credits reduce tax or create a payment. Some benefits are based on adjusted family net income, so one spouse’s income can affect the other spouse’s eligibility.

Children should be added accurately, including their dates of birth and custody arrangements. The CRA may use tax information to calculate the Canada Child Benefit and related provincial or territorial programs. Filing on time helps prevent interruptions, even if a parent had little or no income.

Family item What it may affect Records commonly needed
Children and custody Canada Child Benefit and provincial credits Birth details, custody documents
Childcare costs Child care expense deduction Provider receipt and payment records
Medical expenses Medical expense tax credit Receipts and payment dates
Tuition Tuition credit and education-related amounts T2202 from the school
RRSP contributions Deduction from taxable income RRSP receipt
Donations Charitable donation tax credit Official donation receipt
Low or modest income GST/HST credit and other supports Completed annual return

Report income and claim deductions

Enter every source of income, including part-time wages, tips, freelance payments, bank interest, pensions, scholarships, and government benefits. Some payments may be taxable even when no tax was withheld at the time. Compare your entries with CRA records before submitting.

Deductions are different from credits because they lower the income used to calculate tax. Eligible RRSP contributions, childcare expenses, and certain employment expenses may reduce taxable income. Do not claim an expense simply because it was related to work or family life; keep documentation and confirm that it meets CRA rules.

If you sold investments, received rental income, or worked in the gig economy, additional forms may be required. Keeping a simple income-and-expense spreadsheet throughout the year can make the next tax season faster and reduce overlooked items.

Review, submit, and track the return

Before filing, check names, addresses, direct-deposit details, marital status, and the number of dependants. Confirm that each slip has been entered once and that credits are assigned to the family member who is allowed to claim them. Many software programs run an error check, but a careful review is still necessary.

The usual deadline for most individuals is April 30. Self-employed people generally have until June 15 to file, although any balance owing is usually due April 30. Late filing can lead to penalties and interest when tax is owed, and it may delay income-tested benefits.

After submitting, save the confirmation number and a copy of the return. A notice of assessment explains the CRA’s calculation, refund, balance owing, and available contribution room. If the result differs from your estimate, compare the assessment with your records before contacting the CRA.

Keep records and correct mistakes

Keep tax returns, notices of assessment, receipts, and supporting documents for at least six years. Digital copies are useful, but store them in a secure location with backup protection. CRA may request proof of a claim after the return is processed.

Mistakes do not necessarily require a brand-new return. Once the assessment is available, you can often request a change through CRA My Account or submit the appropriate adjustment request. Correct errors promptly, especially missing income, incorrect marital status, or an overclaimed credit.

A simple filing checklist

Use this short checklist before pressing submit:

Once the return is filed, mark the next tax season on the family calendar and keep documents in one place throughout the year. A few minutes of monthly record-keeping can make income reporting, benefit applications, and household budgeting much more manageable.

Gather the documents, choose a secure filing method, and submit accurate information before the applicable deadline. Completing a first return gives your family a clearer view of its tax position and helps ensure that eligible Canadian benefits are calculated without unnecessary delays.
