What to do if your CCB is audited by the CRA
A Canada Child Benefit (CCB) audit or review can feel alarming, especially when the payments help cover food, housing, childcare, and school expenses. The Canada Revenue Agency (CRA) may ask for documents to confirm your family situation, income, residency, or responsibility for a child.
Receiving a review letter does not automatically mean you did anything wrong. It usually means the CRA needs additional evidence before confirming, changing, or continuing your benefit entitlement. Read the request carefully and note the response deadline.

Read the CRA letter carefully
The letter should explain what information the CRA wants, which benefit period is being reviewed, and how to submit your documents. It may request proof of the child’s residence, school or medical records, custody details, immigration status, or evidence that you are the primary caregiver.
Check whether the CRA is reviewing one child, several children, or your entire CCB file. Also confirm whether the request concerns your family income, marital status, shared custody, or a change in address. These details determine which records will be useful.
Mark the deadline on your calendar. If you cannot collect everything in time, contact the CRA before the deadline and explain what is delaying your response. Ask whether an extension or alternate document is available, and keep notes about the call.
Gather clear supporting documents
Your evidence should match the issue identified in the letter. For caregiving responsibility, useful records may include daycare invoices, school correspondence, medical documents, activity registrations, or statements from a social worker, teacher, or other professional. Documents should show names, dates, and the child’s address where relevant.
If the CRA is checking residence or immigration status, provide lease records, utility bills, health-care documents, school registration, immigration papers, or other official correspondence. For shared custody, include a court order, written parenting agreement, or a detailed schedule showing how the child’s time is divided.
Do not send unrelated paperwork in large quantities. Organize files by child and by issue, use readable copies, and add a short explanation when a document may not be self-explanatory. Keep the originals and save proof that your response was submitted.
Check income and family information
CCB eligibility is calculated using information from tax returns, including adjusted family net income. Make sure you and your spouse or common-law partner have filed the required tax returns for the relevant years. An unfiled return can interrupt payments even when the family otherwise qualifies.
Review the marital-status information on your CRA account. A separation, reconciliation, new common-law relationship, adoption, birth, or change in custody can affect the benefit amount. The CRA generally expects relationship changes to be reported promptly, rather than waiting for the next tax return.
| Issue under review | Records that may help | Possible effect |
|---|---|---|
| Primary caregiving | School, daycare, medical, or activity records | Benefit may be assigned to the appropriate caregiver |
| Shared custody | Parenting schedule, agreement, or court order | Each eligible parent may receive an adjusted amount |
| Family income | Filed tax returns and notices of assessment | Payment amount may increase or decrease |
| Residency | Lease, utility, school, or government records | Eligibility may depend on Canadian residence |
| Child’s identity or age | Birth, adoption, or immigration documents | Confirms the child qualifies for the benefit |
Submit the response securely
Use the submission method listed in the CRA letter. Depending on the request, this may include CRA My Account, an online document service, fax, or mail. Upload files in accepted formats and check that every page is legible before sending.
Include the reference number from the letter and a cover note describing what you are providing. If another person submits documents for you, make sure the CRA has the required authorization. Never email sensitive records to an unverified address or share your CRA login details.
After submitting, save the confirmation number, upload receipt, fax report, or tracking information. Keep a copy of the complete response. These records can be important if the CRA says it did not receive your documents.
Respond if your payments change
The CRA may continue payments, adjust the amount, stop future payments, or assess an overpayment after reviewing your file. Read the notice of determination or reassessment carefully. It should explain the benefit period, calculation, and amount the CRA believes was paid incorrectly.
If you disagree, compare the decision with your documents and contact the CRA promptly. Ask for an explanation of the calculation and provide any missing evidence. If the issue is not resolved, review the dispute or objection instructions included with the notice; deadlines can apply.
An overpayment does not always have to be paid in one installment. Ask the CRA about repayment arrangements if the amount creates financial hardship. Ignoring the balance can lead to collection action, while early communication may allow a manageable plan.
Keep records for future reviews
Store the CRA letter, your submitted documents, delivery confirmation, notices, and call notes together. Tax and benefit records are generally kept for six years, although the CRA letter may require a longer or different retention period for a specific matter.
If you receive CCB, update your address, banking information, marital status, custody arrangements, and children’s information when circumstances change. Filing tax returns on time each year also helps prevent avoidable interruptions.
Families dealing with several benefit issues may also need to review related payments. For example, information about GIS back payments can be useful when supporting an older family member with a separate CRA or Service Canada matter.
Practical steps before the deadline
- Read the entire CRA letter and identify every requested item.
- Gather documents that show dates, addresses, caregiving, income, or custody.
- Submit a clear, organized response through the approved channel.
- Save confirmation of delivery and copies of everything sent.
- Contact the CRA early if documents are missing or repayment would cause hardship.
A CCB review is easier to manage when you respond on time, provide targeted evidence, and keep a detailed paper trail. Use the CRA’s instructions as the primary authority, and seek help from a qualified tax professional or community tax clinic if the case involves complex custody, residency, or repayment issues.
