CPA vs tax preparer: which do you need?

Anyone in Canada can charge to prepare a tax return. Here is what the CPA designation actually adds, and when a straightforward return genuinely does not need one.

Short answer

Tax preparation is unregulated in Canada — anyone can charge for it. A CPA is licensed by a provincial order, carries mandatory professional insurance, and can represent you in an audit and advise on structure. For a single-T4 return with no other income, a preparer is usually fine.

The difference shows up after filing, not during

For a simple return, both routes produce the same numbers. The difference appears when something goes wrong six months later: a review letter arrives, an assessment changes, or a claim is denied. A CPA is still there, is regulated, and carries insurance. A seasonal storefront may have closed for the year. That gap is what you are paying for, and on a simple return it may genuinely not be worth it.

When a preparer is the right call

  • A single T4 with no other income sources
  • Standard credits only — no rental property, no business, no foreign assets
  • No investment income beyond a T5 or two
  • No corporation, no self-employment, no property sale during the year

When you want a CPA

  • You have self-employment or corporate income
  • You sold property, or emigrated from or immigrated to Canada during the year
  • You hold foreign assets over the T1135 reporting threshold
  • You are being reviewed or audited, or you were reassessed
  • You are making a decision — incorporating, restructuring, selling — where the tax result depends on how it is set up

FAQ

Is tax preparation regulated in Canada?

No. Unlike several other countries, Canada does not license tax preparers. Anyone may charge to prepare and file a return, with no required training, examination or insurance. The CRA does require anyone filing more than a small number of returns to register for an EFILE number, but that is an administrative screen, not a professional credential.

Will a CPA get me a bigger refund?

Not on a simple return — the same inputs produce the same result. On a return with judgment in it, the difference is real: what is deductible, how an expense is characterised, which spouse should claim what, whether an election is worth filing. Those decisions do not appear on a straightforward T4 return.

What if my preparer made a mistake on a past return?

You remain responsible for what was filed under your name, which is why recourse matters. Past returns can generally be corrected by filing an adjustment request, going back up to ten years for most individual matters. If a mistake is discovered, correcting it voluntarily is almost always better than waiting for the CRA to find it.

Still not sure which way to go?

The right answer depends on numbers that are specific to you. Talk it through with a Montréal CPA — in English or French.
