Information and professional decisions
Guides explain general recordkeeping practices and identify rules relevant to the subject and review date. A rate, deadline or example may not apply to a different entity, reporting period, registration status or transaction. Refer to the linked authority and the facts of your business before making a filing or legal decision.
A website enquiry does not appoint a representative, create an accountantâclient engagement, authorize tax filing, or establish a price or completion date. The agreed service scope determines who prepares records, approves adjustments, files returns and releases payments.
Examples and calculators
Worked examples are illustrative and are not client results. Calculator outputs depend on the numbers entered and the assumptions shown beside the result. They are planning aids, not quotes, promises of savings, professional opinions or filed returns.
The tools provide a document checklist, a limited filing-versus-payment planner and the 2026 personal instalment threshold test. They do not calculate income tax, refunds, penalties, interest or instalment amounts. A corporate balance extension requires all CRA conditions; the planner does not establish eligibility. Special filing situations and taxpayer-specific CRA instructions need separate review.
Enquiries and safe use
Provide accurate contact information and a brief description of the work. Do not submit sensitive financial documents or credentials through the public form. Do not use the website to impersonate another person, transmit malicious content or interfere with other visitors.
You remain responsible for reviewing an enquiry before submitting it. Calculator buttons prepare a summary; they do not submit the hosted form or authorize services on your behalf.
Content and external references
You may use the checklists to organize your own business records and share links to the guides. Website text, design and other materials remain subject to their applicable ownership and licence terms. Third-party icons and images retain their respective licences.
Links to government bodies, financial institutions, software vendors or local organizations are supplied as references. A reference does not imply membership, certification, partnership, endorsement or a guaranteed integration. Those organizations control their own services and terms.
Questions or corrections
If a link fails, a rule has changed or an example is unclear, send the page address and describe the issue. Requests about an existing engagement should follow that engagementâs agreed communication process.
