What Our CRA Audit Representation Services Include
Our CRA audit representation services run from the first letter to the final notice.
We register as your representative with the CRA, so auditors contact us directly and nothing you say informally can be used against your file.
We review the returns under audit, assemble the supporting documents, prepare every written response, and attend meetings with the auditor on your behalf.
We answer only what is asked. Volunteering extra records is how small audits grow into large ones, so each response is limited to the specific items and years the CRA has questioned. That discipline is the core of the service.

How Our Tax Audit Representation in Canada Works
Tax audit representation in Canada follows deadlines set by the CRA, so our process is built backwards from each one. Here is what happens on your file.
- Step 1
We read the letter the same day you send it.
Audit letters, review letters, and proposal letters carry different deadlines and different rights. Identifying which one you received decides everything that follows.
- Step 2
We register as your representative.
Once authorized, the CRA directs calls and letters to us. You stop fielding auditor questions cold, which matters because unprepared answers create most audit problems.
- Step 3
We reconcile your records before the CRA sees them.
Receipts, invoices, bank statements, and ledgers are matched to the amounts on the return. Gaps are found by us first, so we can explain them rather than have an auditor discover them.
- Step 4
We respond to the proposal letter in full.
Before finalizing changes, the auditor sends a proposal, usually with 30 days to respond. This is the cheapest stage to win, because a proposal cannot be formally objected to, only answered. We use it fully.
- Step 5
We escalate only when the numbers justify it.
If the reassessment still lands wrong, we file the objection and, where needed, brief a tax lawyer for the Tax Court stage. You get a cost-versus-recovery estimate first, because fighting a small adjustment can cost more than accepting it.
CRA Review Representation for Letters That Are Not Full Audits
Most CRA letters are reviews, not audits.
Pre-assessment reviews, processing reviews, and matching letters ask you to prove specific claims, such as medical expenses, donations, or a slip the CRA thinks you missed.
Our CRA review representation handles these end to end: we pull the documents, format them to the CRA's request, and file before the stated deadline.
Ignoring a review letter is the expensive mistake.
If no reply arrives, the CRA simply denies the claim and reassesses you, adding interest that compounds daily. A complete reply by the deadline usually closes the file without any change.
CRA Reassessment Assistance and Objections
Already reassessed?
Our CRA reassessment assistance starts with the two deadlines printed into the law.
You generally have 90 days from the date on the notice to file an objection.
Individuals get the later of 90 days or one year after that return's filing deadline.
Miss the window and an extension request is possible for up to one more year, but it is granted only with a valid reason, so we treat 90 days as the real deadline.
The objection goes to the CRA's Appeals Division, which reviews the file independently of the original auditor, as set out in the CRA's guide to filing an income tax objection. We draft the objection with the disputed amounts, the facts, and the supporting documents attached, because appeals officers decide on what is in front of them.
Collection of disputed income tax is generally paused while the objection is reviewed, though interest keeps running, and we tell you clearly whether paying under protest is cheaper for your numbers. If the objection is confirmed against you, a Tax Court appeal must be filed within 90 days, and we prepare that handover with counsel.
CRA Audit Help Across Canada, From Our Mississauga Office
Audit files are document work, so location rarely limits us. Clients who want CRA audit representation in Mississauga, Brampton, or Toronto can meet us in person at our Hurontario Street office, and we provide CRA audit help across Canada through secure document upload and video meetings. The CRA already works with representatives remotely, so an out-of-province client loses nothing.
Local still matters for one thing. Businesses reassessed after a review often need their books corrected so the problem does not repeat next year. Because Bestax also prepares corporate tax returns and personal income tax filings, the fixes go into your next filing, not into a memo you have to hand another firm.
Deadlines That Decide Your File
| Stage | Deadline | Why we act before it |
|---|---|---|
| Review or audit letter | Date stated in the letter, often 30 days | No reply means the claim is denied and interest starts compounding daily |
| Auditor's proposal letter | Usually 30 days to respond | A proposal cannot be objected to, only answered, so this is the last cheap stage |
| Notice of objection | 90 days from the notice date; individuals get the later of 90 days or 1 year after the filing deadline | The Appeals Division only opens files that arrive on time |
| Missed objection deadline | Extension request within 1 year, with reasons | Extensions are discretionary, so we never plan around one |
| Tax Court appeal | 90 days from the confirmation | After this, the reassessment becomes final |
Why Choose Bestax for CRA Audit and Review Files
Deadlines are logged before opinions are formed.
The first action on every file is calendaring each date above, because a strong argument filed late is worth nothing.
Responses are built from reconciled books.
Every figure we send the CRA is tied to a bank record, invoice, or ledger entry first. Auditors test claims against source documents, so we test them the same way before submission.
Scope is kept narrow.
We answer the questions asked, for the years asked. Files stay small when nobody widens them voluntarily.
You get a cost-versus-recovery estimate before any dispute.
Objections take months and interest runs through them. If the disputed tax is smaller than the cost of fighting it, we say so before you spend anything.
The same firm fixes the cause.
When an audit exposes a bookkeeping or filing problem, we correct it in your next return. Representation that ends at the notice leaves you exposed to the same letter next year.
