From January to April 2027, Canadian self-employed people and small businesses need their 2026 records in order, which creates short-term work for anyone with bookkeeping skills. The lowest-barrier gigs are catch-up bookkeeping, categorizing a year of bank transactions, and organizing receipts so a client or their accountant can complete Form T2125. Preparing and electronically filing other people’s returns is a step further: the CRA’s EFILE service is for approved tax preparation service providers, and any firm or individual offering tax preparation can apply if they pass suitability screening. Volunteering at a free tax clinic is a way to build experience, but it is unpaid. Job Bank lists Canadian bookkeeper wages at a median of $28.02 an hour, a useful benchmark for your rate.

Which tax-season gigs can you do in Canada?
The gigs range from data clean-up that needs no CRA registration to e-filing returns, which does.
| Gig | Who buys it | What you need | Registration |
|---|---|---|---|
| Catch-up bookkeeping | Self-employed people, small businesses | Bookkeeping skills and software | None from the CRA for bookkeeping itself |
| Receipt and statement clean-up | Side hustlers before T2125 | Spreadsheet skills, attention to detail | None |
| Year-end package for an accountant | Small businesses with an accountant | Reconciled books and a summary | None |
| Preparing and e-filing returns | Individuals and businesses | Tax knowledge and EFILE access | EFILE application and suitability screening (EFILE) |
| Volunteer at a free tax clinic | People with modest income and simple returns | CVITP volunteer registration | Unpaid (free tax clinics) |
What do you need to prepare tax returns for clients?
To e-file returns for others, you need EFILE access, and to view a client’s CRA information you need their authorization.
- EFILE: the CRA describes EFILE as a service for approved tax preparation service providers and discounters. Any firm, organization, or individual providing tax preparation services can apply if they meet the applicant requirements and pass suitability screening. In 2026, EFILE opened for 2025 returns on February 23, 2026; check the CRA page for the 2027 opening date.
- Volunteers: CVITP volunteers register with the program first, and those who intend to transmit returns by EFILE under CVITP must also apply for an EFILE number.
- Client access: since July 15, 2025, representatives of individual clients request online access through the Represent a Client portal rather than EFILE. Clients can also add you in My Account (how to give authorization).
- Scams: the CRA warns EFILERs that it will never send a message asking for an EFILE ID and password.
What are the key 2027 tax-season dates?
Based on the CRA’s filing rules, 2026 returns are generally due April 30, 2027, and self-employed people and their spouses have until June 15, 2027 to file, but any balance owing is still due April 30 (filing due dates). The CRA’s page currently shows the 2025 dates; confirm the 2026-return dates when it updates. Bookkeeping clients usually need clean books well before April so their preparer has time.
| Date | What it means for your clients |
|---|---|
| January–February 2027 | Clients gather slips and statements; catch-up bookkeeping window |
| Late February 2027 | EFILE typically opens (February 23 in 2026) |
| Friday, April 30, 2027 | Filing deadline for most people; balance due for everyone |
| Tuesday, June 15, 2027 | Filing deadline for self-employed people (balance still due April 30) |
How should you price tax-season bookkeeping?
Price catch-up work by the project once you have seen the records, using an hourly estimate. Job Bank’s wage data for bookkeepers in Canada shows $19.55 low, $28.02 median, and $45.07 high per hour for 2023–2024 (Job Bank). Those are employee wages; a freelancer’s rate also has to cover unpaid admin time, software, and both shares of CPP.
Illustrative example
Assume a side hustler with 12 months of transactions in one bank account and a shoebox of receipts. The hours and rate are assumptions.
- Estimate: 1 hour per month of transactions = 12 hours, plus 3 hours for receipts and a summary = 15 hours.
- At $40 an hour: 15 × $40 = $600 as a flat project fee.
- Five clients over January to March: 5 × $600 = $3,000 before tax and software.
What mistakes do people make with tax-season gigs?
The common mistakes are offering tax filing without EFILE access and taking on records you cannot finish by April.
- Filing for clients without EFILE. Apply and pass screening first.
- Asking for client passwords. Use Represent a Client authorization instead.
- Quoting before seeing the records. Scope first, then price.
- Taking too many March clients. Cap your workload before the April crunch.
- No engagement letter. Write down what you will and will not do, and that you are not giving tax advice unless you are qualified to.
Which tax rules apply to your own tax-season income?
Your bookkeeping or tax-prep fees are generally business income on Form T2125. Keep your own records as the CRA’s business records guidance requires, generally for six years. Accounting software such as FreshBooks TODO-AFFILIATE can handle invoicing and expense tracking for you and your clients. See freelance bookkeeping startup costs for software and insurance.

What are the common questions?
Can I do tax preparation as a side hustle in Canada?
Yes. To e-file returns for clients you apply for EFILE; the CRA says any firm, organization, or individual providing tax preparation services can apply if they meet the requirements and pass suitability screening. Bookkeeping and receipt clean-up need no CRA registration.
How much do bookkeepers earn per hour in Canada?
Job Bank lists bookkeeper wages in Canada at $19.55 low, $28.02 median, and $45.07 high per hour for 2023–2024. Freelancers usually charge more than employee wages to cover admin time, software, and CPP.
When is the 2027 tax filing deadline?
Under the CRA's filing rules, 2026 returns are generally due April 30, 2027, and self-employed people have until June 15, 2027 to file, with any balance due April 30. Confirm on the CRA's filing dates page.
Is volunteering at a free tax clinic paid?
No. The Community Volunteer Income Tax Program uses volunteers to complete returns for people with modest income and simple tax situations. It can build experience but is not a paid gig.
How do I get access to a client's CRA account?
Representatives of individual clients use the Represent a Client portal to request access, and clients can also authorize a representative in My Account. Do not ask clients for their CRA passwords.
