Receiving an audit notice from the Canada Revenue Agency (CRA) or the Internal Revenue Service (IRS) can be intimidating, but understanding the process — and knowing when to bring in professional representation — can significantly improve your outcome.
## Step 1: Don't Panic, But Don't Ignore It
Audit notices have response deadlines. Ignoring correspondence typically leads to worse outcomes, including estimated assessments based on limited information, which are often higher than what you'd owe with proper documentation. Read the notice carefully to understand exactly what is being examined — it may be a full audit or a narrower review of specific line items.
## Step 2: Understand What's Being Reviewed
Audits vary in scope. A "desk audit" or correspondence review typically focuses on one or two specific items (like a claimed deduction or credit) and can often be resolved by mail with supporting documentation. A full field audit examines your entire return and may involve an in-person or virtual meeting with an auditor.
## Step 3: Gather Documentation
Organize supporting records for the items under review: receipts, invoices, bank statements, mileage logs, and any other substantiation. Both the CRA and IRS generally require taxpayers to retain records for a minimum number of years (typically 6-7 years), so having organized bookkeeping throughout the year pays off enormously during an audit.
## Step 4: Consider Professional Representation
You are generally entitled to have a tax professional represent you during an audit. An Enrolled Agent, CPA, or Chartered Accountant experienced in audit representation can:
- Communicate directly with the auditor on your behalf
- Ensure your rights as a taxpayer are respected
- Identify which requests are reasonable and which exceed the audit's scope
- Negotiate settlements or payment arrangements if additional tax is owed
- Prepare a clear, well-organized response that reduces the likelihood of an expanded audit
## Step 5: Respond Within Deadlines
Whether working with a professional or responding yourself, meet all stated deadlines. If you need more time, both agencies generally allow extension requests if submitted before the original deadline.
## Step 6: Understand Your Appeal Rights
If you disagree with an audit's findings, both the CRA (through a Notice of Objection) and IRS (through the Office of Appeals) offer formal processes to dispute assessments before matters proceed to tax court.
## When to Bring in a Specialist
If your audit involves complex business deductions, cross-border income, cryptocurrency transactions, or a proposed reassessment of significant size, specialized audit representation becomes particularly valuable. Look for firms on Tax Pro Local offering "CRA Audit Help" or "IRS Audit Help" as a listed specialty — these firms have direct experience navigating the audit process and negotiating with tax authorities on behalf of clients.
The earlier you engage professional support after receiving an audit notice, the more options you typically have to shape a favorable outcome.
