The word “audit” carries more dread than almost anything else in personal finance, and the reality is considerably less dramatic than the reputation. Most examinations are narrow, procedural, and resolve without anyone appearing in front of anyone.
That said, they’re not nothing, and how you handle the first few weeks materially affects the outcome.
First: it’s probably not an audit
Most correspondence from a tax authority isn’t an examination. Automated matching notices — where reported income doesn’t line up with what’s on the return — are far more common and are covered separately.
An actual examination is identified as such and says clearly that a return has been selected for review. If your letter doesn’t say that, it probably isn’t one.
Why returns get selected
Several routes, and they’re not all about suspicion.
Statistical scoring. Returns are scored against expected patterns for comparable returns. A figure well outside the normal range for similar circumstances can raise the score. Note that unusual isn’t the same as wrong — genuinely unusual situations exist, and having one isn’t an accusation.
Document mismatches. Something reported to the authority that doesn’t appear on the return.
Related examinations. A business partner, a related entity, or a transaction counterparty under examination can bring your return into scope.
Specific focus areas. Authorities periodically concentrate on particular areas or industries.
Random selection. Some proportion genuinely is random, used to calibrate the scoring systems. Sometimes there’s no story.
The forms it takes
Correspondence examination. By far the most common. Conducted entirely by mail, typically focused on one or two specific items. You send documentation supporting the item, it’s reviewed, and it resolves. Many are closed with no change at all.
Office examination. Conducted at a tax authority office, broader in scope, involving a meeting. With representation, your representative attends and you generally don’t.
Field examination. The most comprehensive, conducted at your business or your representative’s office, typically for businesses or complex returns. Also the least common.
The scope of each is defined. An examination of specific items is not a general licence to review everything, and keeping the scope contained is a significant part of what good representation does.
What determines the outcome
Documentation. Overwhelmingly the deciding factor. A position with contemporaneous supporting records generally holds. The same position with nothing behind it generally doesn’t, however true it is. This is why recordkeeping habits matter long before anyone asks.
Consistency. Documentation that contradicts itself, or contradicts other years, causes more difficulty than a straightforward gap.
Scope management. Answering questions specifically. Unrepresented taxpayers, trying to be helpful and cooperative, routinely volunteer material that expands an examination into areas nobody was looking at. This is the single most common self-inflicted harm.
Timeliness. Responding within deadlines, and requesting extensions properly when needed rather than simply missing them.
What representation actually does
With authorization on file:
The correspondence redirects. Letters and calls go to your representative.
You don’t attend. For office and field examinations, your representative goes instead.
Responses are prepared. Questions get answered after consideration rather than improvised under pressure.
Someone knows what’s normal. Whether a request is standard or unusually broad, whether a proposed adjustment is reasonable, whether something is worth contesting. Judgment that comes from volume.
The scope stays contained. Perhaps the most valuable part.
You can represent yourself. People do, and for a narrow correspondence examination on a well-documented item it can be fine. As scope and stakes increase, the calculation shifts quickly.
Possible outcomes
No change. The return is accepted as filed. Genuinely common, particularly for correspondence examinations on well-documented items.
Agreed adjustment. Something was wrong, you accept the correction, additional tax and interest follow. Penalties may or may not apply.
Disagreed adjustment. You don’t accept the conclusion. This is not the end — it moves to appeals, which is a separate function with its own standards, and cases do change there.
Adjustment in your favour. Uncommon, but it happens. An examination can find something that was overstated.
Rights worth knowing
You have the right to representation at any point, including partway through. If an examination begins and you decide you want representation, you can stop and arrange it.
You have the right to understand why information is being requested and what will happen with it.
You have the right to appeal, and to be told how.
You have the right to be treated professionally, and a route to escalate if you aren’t.
Practical advice
Don’t panic, and don’t ignore it. Both are common, and ignoring it is much worse. Examinations proceed on their own schedule with or without you, and an unresponded examination concludes on the authority’s terms.
Don’t volunteer. Answer what’s asked. Being expansively helpful is the most common way unrepresented taxpayers make it worse.
Don’t guess. “I think it was around…” creates a record. If you don’t know, say you’ll check.
Get representation early. Easier to conduct an examination well from the start than to correct course partway through.
Keep everything. Every letter, every request, dated. If it becomes contested, the chronology matters.
Afterward
Once it closes — and it will close — it’s worth understanding why it happened. Sometimes genuinely random. Often a reporting pattern or documentation habit that can be changed.
And check whether other open years have the same exposure. Fixing it prospectively is much cheaper than doing this again.
