1.1.0 Acknowledgements
The Compliance Programs Branch recognizes the hard work by subject matter experts and the support of management from the tax services offices (TSOs) in developing and maintaining this manual.
1.2.0 Background
The Income Tax Audit Manual (ITAM) consolidates operational policies and procedures for the administration of income tax. Before November 2012, the Audit Manual was a combined income tax and goods and services tax / harmonized sales tax (GST/HST) manual.
The material in the ITAM reflects national audit policies and recommended procedures. The taxation operations manuals (TOMs) and GST/HST audit manuals have been taken out of circulation. Communiqués, directives, and policy statements will be archived for reference when out of date or cancelled when superseded by new policy or legislation.
The unsevered ITAM is available to Canada Revenue Agency (CRA) auditors in the CRA Electronic Library. For more information, go to 1.10.0, The CRA Electronic Library.
The severed ITAM is available to the public on the Canada.ca website at Income Tax Audit Manual. Due to its size, chapters of the ITAM are being added to the website as they become available.
Printing the ITAM is not recommended.
1.3.0 Sources of Information for the Income Tax Audit Manual
The ITAM includes information from TOMs 10, 13, and 14, communiqués, directives, memoranda, and policy statements.
1.4.0 Intended Users
The ITAM is written for employees involved in the audits of income tax for small and medium-sized businesses; however, the information can also be applied in other areas such as large business and specialty audit.
1.5.0 Scope and Authority
The contents of the ITAM reflect the national policy on operations, procedures, and technical applications as authorized by the program areas and the Policy Section within the Small and Medium Enterprises Directorate.
The ITAM is a single source of reference for audit policies and procedures and technical application guidelines about audit issues. To conduct research efficiently and effectively, use the ITAM search system to access information to plan, prepare, conduct, and complete an audit. The ITAM includes:
- examples of audit checklists and working papers
- audit techniques
- technical information to apply legislation administered by the CRA
- references to court cases
1.6.0 Maintenance of the Income Tax Audit Manual
The Policy Section of the Small and Medium Enterprises Directorate and the Policy Section of the GST/HST Directorate work together to make sure common audit issues are addressed consistently.

1.8.0 Updates
1.8.1 What's New
"What’s New" in the Compliance Programs Branch Reference Material lists updates to the CRA Electronic Library every two months, including communiqués, memoranda, letter templates, revised sections of the ITAM, and other operational manuals.
Communiqués, memoranda, and letter templates can be viewed directly under “Audit” by expanding (click the + sign) the section.
When a section of the ITAM is updated, the section reference is included in the listing under Operations Manuals > Audit Manuals > Income Tax Audit Manual. Within the chapters, updated text is marked with a sidebar, which is removed in the next publication.
The ITAM is published every two months and there are always changes as the Policy Section updates for policy changes, legislative changes, broken or outdated links, and language clarity.
"Corrected text" normally means corrected grammar, or spelling errors OR to make the French and English text mean the same.
"Clarified text" normally means that the phrasing has changed or an additional line of explanation has been added. The meaning of the text remains the same, but it may now be clearer for some.
Most other changes are clearly described as to what the change was.
For more information on revisions, email Income Tax Audit Manual / Manuel de la vérification – Impôt (CRA/ARC).
1.9.0 Recommending Changes or Additions to the Income Tax Audit Manual and Letter Templates
The ITAM and letter templates are regularly updated. Comments and suggestions for improvement are welcome.

The CRA version of the electronic library houses the ITAM and includes a comprehensive coverage of income tax, excise tax, GST/HST, provincial taxes, and customs information, as well as links to other tax-related information.
The CRA version of the electronic library can be accessed through the Centralized Technology Platform (CTP). The use of the CTP ensures the user access to the most recent information.
1.11.1 Local Area Network (LAN) Version
Follow the steps below to access the ITAM:
Step 1
Use this path to access the CRA Electronic Library:
Single left-click on the Windows icon and the "All apps" start menu will open
Expand the "CRA Electronic Library {CTP-PTC}" folder
Single left-click on "CRA Electronic Library – EN"
Text version
Image explained: This screenshot is of the Windows start menu. Single left-click on the Windows icon for a menu of the programs installed. Expand the "CRA Electronic Library {CTP-PTC}" folder for a final menu of options to select "CRA Electronic Library - EN."
Note: If you do not see "CRA Electronic Library {CTP-PTC}" after clicking on the Windows icon and you are a regular user of these applications, please call or email your local IT Service Desk and ask that they install the Common User Desktop (CUD) on your workstation. Your local IT section will fill in a request form and send it to the CTP project team to add your user ID.
