What you should know about audits
The Canada Revenue Agency (CRA) administers tax laws and various benefit
programs for the Government of Canada and several provinces and territories.
Audits are an important part of the CRA's range of activities aimed at making
sure the tax system is fair for everyone. During an audit, the CRA closely
examines the books and records of a taxpayer to confirm whether they are
fulfilling their tax obligations, following tax laws correctly, and receiving
the benefits and refunds to which they are entitled.
Most taxpayers comply with the tax laws in Canada. The CRA's auditing
processes help these taxpayers better understand and meet their obligations,
as well as help to maintain public confidence in the fairness and integrity
of Canada's tax system.
If your file has been chosen for an audit, the CRA has information available
to help you with the audit process. This publication gives you some
information to get started.
How does the CRA choose a file for an audit?
The CRA chooses a file for an audit based on a risk assessment. The
assessment looks at a number of factors, such as the likelihood or frequency
of errors in tax returns or whether there are indications of non-compliance
with tax obligations. The CRA also looks at the information it has on file
for the taxpayer and may compare that information to similar files or
consider information from other audits or investigations.
How does the CRA do an audit?
What is the first step in the audit process?
A CRA auditor will contact you by mail or phone, or both, to start the audit
process and tell you the date, time, and location of the audit.
Normally, an on-site audit takes place at your residence, your place of
business, or at your representative's office. The auditor will present you
with a valid identification card upon arrival, and then start the audit. An
on-site audit often allows questions to be addressed quickly and can minimize
delays in completing the audit.
If an audit is not done on-site, it will take place at a CRA office. The CRA
makes the best use of its resources by centralizing the management of some
audit files in particular CRA office locations. This means that you may be
assigned an auditor who is located outside your region. In that case, the
auditor will ask you to bring or send any supporting documents required for
the audit.
Wherever an audit takes place, the auditor may need to make copies of your
electronic records or borrow some of your documents. The auditor will give
you a detailed receipt for any borrowed documents and return them as soon as
possible.
Sending your records online to the CRA
Auditors are not allowed to receive records by email because information sent
this way may not be secure. Your assigned auditor can provide information
about how you can send documents online using the CRA's secure services.
Did you know?
- Your personal records and the personal or business records of other
individuals or entities are legally considered to be part of the items that
relate, or may relate, to a tax return being audited, and can be reviewed by
a CRA auditor.
- An auditor can examine the records of family members.
- An auditor may ask the employees who do your accounting entries about your
business operations.
What does an auditor examine during an audit?
An auditor will examine books and records, documents, and information
(collectively referred to as records). These include the following:
- information available to the CRA (such as filed tax returns, credit
history, and property details)
- your business records (such as ledgers, journals, invoices, receipts,
contracts, rental records, and bank statements)
- your personal records (such as bank statements, mortgage documents, and
credit card statements)
- the personal or business records of other individuals or entities not being
audited (for example, a spouse or common-law partner, family members,
corporations, partnerships, or a trust [settlor, beneficiary, and trustee])
- adjustments made by your bookkeeper or accountant for tax purposes
During an audit, the auditor may find issues and discuss them with you. You
can also raise concerns with the auditor at any time.
After the auditor examines the records provided, a number of things can
happen:
- Correct assessment: If the auditor finds that your previous assessment is
correct, nothing more has to be done. You will receive a completion letter
and the audit will be closed.
- More taxes owed or a refund: If the auditor finds that your return has to
be reassessed (which means you may have to pay more tax or be entitled to a
refund), you will receive a proposal letter explaining the reason for the
reassessment. You will have 30 days to agree or disagree with the proposal.
If you disagree with the proposal, you are encouraged to contact the auditor
to explain why you disagree and provide any other documents that support your
position. The auditor will carefully consider your explanations and respond
to your questions about the proposal.

If an issue is not resolved, you can contact the auditor's team leader to
discuss it. The team leader's contact information is included in all
correspondence sent to you by the auditor.
What happens at the end of an audit?
At the end of an audit, a final letter will be sent to you and one of the
following things will occur:
- no adjustments will be made to your previous assessment
- an adjustment resulting in more tax owing will be made (reassessment), and
you will have to pay the balance owing
- an adjustment resulting in less tax owing will be made (reassessment), and
you will be entitled to a refund
If an adjustment results in more tax being owed, the auditor can give you an
estimate of the amount before the CRA issues a notice of assessment or notice
of reassessment. This will give you the opportunity to avoid interest charges
by paying all or part of what you owe right away, rather than waiting for a
notice. For more information, visit canada.ca/guide-taxes-payments.
What if you don't agree with a reassessment?
If you do not agree with a reassessment, you have the right to appeal it. For
more information, see canada.ca/cra-complaints-disputes.
How long does it take to do an audit?
The time it takes to do an audit depends on a number of factors, such as:
- the state of the records
- the scope of the audit
- potential delays due to missing records
- consultation with other CRA tax specialists
Good records and co-operation with the auditor will reduce the time it takes
to do an audit. If requested records are not provided or are hard to find,
delays can result.
If you no longer have certain records, you have to try to get copies from the
parties that created them (for example, financial institutions or suppliers).
If you can't get the records, you can discuss this with the auditor or the
auditor's team leader who will work with you to find ways to confirm the
amounts reported on your return.
For more information, see canada.ca/taxes-records.
Your rights and responsibilities
What are your rights?
The Taxpayer Bill of Rights is a set of 16 rights that you have as a taxpayer
in your relationship with the CRA.
These rights confirm the CRA's commitment to serve you with a high degree of
accuracy, professionalism, courtesy, and fairness.
To make sure the interactions of small business with the CRA are as effective
and efficient as possible, the Taxpayer Bill of Rights also includes the
Commitment to Small Business.
Under the Taxpayer Bill of Rights, you have the right to file a complaint if
you are not satisfied with the service you receive from the CRA. For more
information, see canada.ca/cra-complaints-disputes.
To learn more about your rights and what you can expect when you deal with
the CRA, see Guide RC17, Taxpayer Bill of Rights Guide: Understanding your
rights as a taxpayer.
Under the Privacy Act, individuals have the right to access, request
correction of personal information, and file a complaint to the Privacy
Commissioner of Canada regarding the institution's handling of the
individual's personal information.
For more information, refer to personal information banks: CRA PPU 421, CRA
PPU 430, CRA PPU 035 on Info Source at canada.ca/cra-info-source.
What are your responsibilities?
By law, you have to keep adequate books and records to determine your tax
obligations and your entitlements. Generally, books and records must be kept
for a minimum of six years.
If you use a computer for your accounting records, you must keep your books
and records in an electronically readable format, even if you also keep them
on paper. Using the services of a tax professional does not relieve you of
your responsibilities.
For an audit, you must make available to the auditor all of your relevant
records (both paper and electronic) and supporting documents, and provide
complete and timely explanations to the auditor's questions. Failure to
provide required books and records is an offence under the law.
