Do you need an accountant for your Canadian tax return?

Can I do my own taxes in Canada, and what are my options?

You can prepare your own personal return. The CRA allows you to file with certified tax software, by paper, through an eligible free service, or through a professional preparer. No rule requires an accountant merely because you have income to report.

A return with employment slips and ordinary deductions is usually a reasonable self-filing candidate if you can verify every entry. Check that the CRA accepted an electronic return: NETFILE gives a confirmation code. Completing a return in software without transmitting it does not file it.

Which returns cannot be filed online?

Online eligibility depends on the return and the filing service. NETFILE lets individuals send returns through tax software; EFILE is for registered preparers. If one service excludes a return, check the other service's current rules before deciding that paper is required.

The taxpayer signs the section 216 or section 217 paper return. A section 216 return is generally due within two years after the year if tax was withheld on gross income; an approved NR6 makes it due June 30 the next year, or April 30 if reporting recaptured capital cost allowance on a sold rental. The non-resident and Canadian agent sign NR6 by January 1 or before the first payment is due. A section 217 return must be filed by June 30 the next year to make the election.

The published restrictions describe the current filing season, which covers an earlier tax year than this page. Check the NETFILE restrictions and EFILE exclusions again when you file. If your completed return cannot use NETFILE, the CRA says you can print and mail it. A paper requirement does not itself mean you need an accountant.

Do I qualify for a free tax clinic?

You may qualify if your family income is modest and your return is simple. The CRA publishes suggested income limits by family size, but each clinic can adjust them and volunteers choose which returns they can handle. Quebec residents should check Revenu Québec's separate volunteer program; a minimal fee may apply to the Quebec return.

The CRA treats employment, pensions, benefits, scholarships, and limited interest as examples of simple income. Its clinic rules generally exclude employment expenses, business or rental income and expenses, capital gains or losses, foreign property reporting, most foreign income, bankruptcy, and a deceased person's return. A narrow exception may apply when total income in box 048 of a T4A is under the CRA's current clinic limit, no expenses are claimed, and the person is neither registered nor required to register for GST/HST. Ask the clinic before relying on that exception.

Which situations make a return more than a simple one?

A return needs more care when the answer depends on records, residency, a sale, or a separate reporting duty. These are reasons to consider tax preparation help, not rules requiring an accountant. The CRA's clinic exclusions are a useful first screen.

If both Canada and the US may tax you, the cross-border accountant guide handles that decision. If the return is for a corporation, see filing a corporate return.

If an accountant prepares my return, who is responsible for mistakes?

You remain responsible for the information on your return even if someone else prepares it. The CRA says this directly and generally treats a representative's errors or delays as yours when considering penalty or interest relief. That does not decide whether a preparer has separate duties or liability.

Give the preparer complete records. Before electronic filing, review the completed return and Form T183, then sign Part F; the form's amounts must match the return. Ask about missing income, unfamiliar deductions, or a result you cannot explain. Keep a copy of the return, T183, and supporting records, then compare the filed result with your notice of assessment.

What should I give an accountant?

Give the preparer the records needed to explain every item on the return. The CRA asks for income slips, receipts for deductions and credits, and other supporting documents. A useful packet includes:

• Your name, address, social insurance number, and marital status; if you have a spouse or common-law partner, their identifying details and net income, even if they file separately.
• All tax slips and income records, including amounts without a slip.
• Receipts and records for deductions, credits, business costs, property purchases, and sales that apply to you.
• Your prior return and notice of assessment, especially for carryforwards or a representative authorization request.
• Dates of a move into or out of Canada and records of foreign income or property, if relevant.
• CRA letters, notices, or a list of unfiled years, if relevant.

The CRA's clinic checklist likewise asks for identification, slips, receipts, and a prior notice of assessment where available. Tell the preparer about missing slips; the CRA's online data may not contain every item when the return is prepared.

How do I give an accountant access to my CRA account?

You can authorize a representative in your CRA account. For a personal account, sign in, open your Individual account, choose Profile, then Add under Authorized representative(s) and enter the requested details. The CRA gives these steps. A preparer can instead submit a request for you to confirm in your account.

Choose the access needed: level 1 lets a representative view information; level 2 also permits certain account changes. If you cannot use the online process, ask about the CRA's alternative authorization methods. Authorizing account access is separate from signing Form T183 to let a preparer transmit your return.

What are the deadlines if I or my spouse is self-employed?

If you or your cohabiting spouse or common-law partner carried on a business, the usual federal filing deadline is June 15 after the tax year, but any balance owing is generally due April 30. The later filing date does not extend the payment date. The Income Tax Act sets the filing dates and excludes businesses whose spending was primarily for tax shelter investments; the CRA lists the filing and payment dates.

File on time even if you cannot pay in full: the CRA charges a late-filing penalty when a late return has tax owing, and interest on unpaid tax. Different dates can apply to a deceased person's return. For the rules on reporting business income, CPP, and instalments, see how self-employed income is taxed.

I live in Quebec: do I file two returns?

Check your filing duties for the tax year: your current address alone does not decide them. Revenu Québec's rules include year-end Quebec residents who meet filing conditions and some people living elsewhere, including those with a Quebec business. If both returns are required, send the federal return to the CRA and the separate Quebec return to Revenu Québec. Check the federal filing duty separately.

You may prepare both yourself using software accepted by the relevant agency, or have a preparer do them. Check the Quebec online filing restrictions separately from federal NETFILE rules. If a preparer files your Quebec return online, sign Quebec's Form TP-1000.TE-V; if they also EFILE your federal return, sign Form T183. Quebec's volunteer clinic eligibility also has its own rules.

CRA representative access does not grant access to Revenu Québec records. If your preparer needs them, authorize access separately through Revenu Québec My Account or form MR-69-V; a download code can also let the preparer download tax data.

Example

Illustrative only; amounts are in Canadian dollars and no tax is calculated. An Ontario employee has a T4 showing CAD $60,000. Their spouse earns CAD $8,000 from freelance work and records CAD $2,000 of related costs. They lived together during the tax year and each has a separate personal return. The employee can still prepare their own return. The spouse's CAD $8,000 receipts less CAD $2,000 of costs leave CAD $6,000 before other adjustments; that business income needs records, and a free clinic would generally decline the spouse's return.

Because they lived together during the tax year and one spouse carried on a business, both normally have until June 15 to file their federal returns. Any balance owing is still due April 30. If a preparer files either return, each person reviews their return and signs Part F of their own Form T183 before EFILE transmission.

Different for you?

• You moved to Canada this year: your residence date and earlier income can change the return. See your first Canadian return or tax preparation help.
• You have freelance or rental income: see self-employed income or rental income.
• You sold a home or hold foreign property: see the principal residence guide or foreign property reporting.
• You missed returns or received a CRA review letter: see catching up or responding to the CRA.
• You also have a US return: see when cross-border help matters or cross-border tax.
• You need to file a corporation's return: see filing your T2.
• Several of these issues apply together or the records are incomplete: gather your slips, notices, receipts, and dates, then seek tax preparation help.
