Doing your own bookkeeping in Quebec: A guide and its limitations (2026)

At a Glance. Doing your own bookkeeping is legal and entirely feasible in Quebec, especially if you have fewer than 25 transactions per month: separate accounts, weekly data entry, monthly reconciliation, tracking the GST (5%) and QST (9.975%) with Revenu Québec, and retaining records for six years. The break-even analysis is straightforward: the median accounting budget for a Quebec SME is approximately $3,000 per year, or about $250 per month, based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received. As soon as your bookkeeping takes up more than 3 to 4 hours a month, outsourcing often becomes more cost-effective than doing it all yourself.

Many Quebec entrepreneurs start out exactly this way: with a spreadsheet, a folder of invoices, and a desire to save money. Good news: doing your own bookkeeping is perfectly legal, and for small-scale operations, it’s an excellent way to learn about business management. This guide provides a comprehensive seven-step method, outlines the requirements you must meet with the CRA and Revenu Québec, and, something few guides dare to quantify, the exact threshold at which delegating becomes more cost-effective than continuing on your own, calculated based on actual fees observed through Bankeo. It complements our guide on the Monthly Cost of Bookkeeping in Quebec.

Doing your own bookkeeping: What the law really requires of you

There is no law requiring a Quebec business to hire a professional to handle its bookkeeping. What the CRA and Revenu Québec require is a result: reliable records, supported by supporting documents, that allow you to determine your income, expenses, and taxes. In practical terms, your obligations boil down to four key areas:

• Records and supporting documents must be retained for six years: Invoices, statements, contracts, and accounting records must be retained for six years after the end of the tax year to which they relate.
• GST and QST if you’re registered: Registration becomes mandatory when your taxable sales exceed $30,000 over four consecutive calendar quarters. You then charge 5% GST and 9.975% QST, and file your returns with Revenu Québec.
• Payroll and source deductions if you have employees: Each pay period involves calculating and remitting source deductions to the CRA and Revenu Québec, followed by the filing of T4 slips and RL-1 slips in February.
• Accurate Year-End Taxes: T1 and TP1 returns with the income statement for a self-employed individual; federal T2 and Quebec CO-17 returns for a corporation.

Only one area remains off-limits: the certification of financial statements (audit or review engagement), which is required by certain lenders or partners, must be performed by a CPA regulated by the Ordre des CPA du Québec. When it comes to day-to-day bookkeeping, the only real question isn’t “Am I allowed to?” but “Is it worth my time?” We address this below, backed by statistics.

A Step-by-Step guide to doing your own bookkeeping

Here’s the method we recommend for entrepreneurs starting from scratch. It consists of seven steps, in order.

1. Keep everything separate from day one. A business bank account and a dedicated card. Mixing personal and business finances is the mistake that’s most costly to untangle later, both in terms of time and denied expenses.
2. Choose a tool that fits your needs. For about 25 transactions per month, a well-structured spreadsheet is sufficient. Beyond that, online accounting software quickly pays for itself: bank integration, pre-programmed GST and QST rates, and automatic reports.
3. Set up a simple chart of accounts. Align your expense categories with those on your year-end income statement (advertising, supplies, rent, vehicle expenses, professional fees, etc.). This will help you avoid having to reclassify everything in the middle of tax season.
4. Set aside 30 to 45 minutes each week for this routine. Record sales and expenses, take photos of each receipt, and file them as you go. Consistency is what separates sound bookkeeping from a costly catch-up effort.
5. Reconcile your accounts every month. Reconcile your books with your bank and credit card statements. A discrepancy spotted within 30 days can be corrected in minutes; the same discrepancy discovered in March can be corrected in hours.
6. Treat GST and QST as funds on deposit. Bill at the correct rates, set aside collected taxes in a separate account, claim your input tax credits (ITCs) and input tax refunds (ITRs), and then file your return with Revenu Québec according to your filing schedule.
7. Prepare for year-end on an ongoing basis. Mileage, mixed-use expenses, inventory (if applicable): keep track of them as you go. In January, your tax return will be processed without any hassle.

Once you’re up and running, here’s how much time this routine actually takes for a small volume of transactions:

To be honest: about 2 to 4 hours per month when the volume is low and you’ve got a routine in place. This is the figure you now need to compare to the cost of outsourcing.

The exact threshold at which outsourcing becomes Cost-Effective

This is the question everyone asks but almost no one quantifies. To answer it, you need two pieces of information: how much it costs to outsource the work, and how much your time is worth.

In terms of cost, we have actual figures rather than estimates: the median accounting budget for a Quebec SME is approximately $3,000 per year, with most businesses falling between $500 and $6,000, based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received. The breakdown by sector is published in the Bankeo Fee Barometer. On a monthly basis, the median cost is around $250 per month; bookkeeping alone, without year-end closing or tax preparation, falls at the lower end of the range, at around $40 per month for the smallest accounts.

The threshold rule can be summed up in one line: threshold (in hours per month) = monthly cost of outsourcing ÷ value of your time. If the number of hours you spend on bookkeeping, multiplied by your hourly rate, exceeds what it would cost to hire a professional, every month you continue to do it yourself costs you money. Here is the break-even analysis:

How to read this table: A self-employed worker who charges $100 per hour and spends 3 hours per month on bookkeeping is already “spending” $300 of their time on this task, for work that, on average, costs around $250 per month to outsource, including the full service. In practice, with an efficient routine of 2 to 4 hours per month, the break-even point is reached as soon as your hourly rate is $75 or more, which applies to a significant number of service-based entrepreneurs. And this threshold doesn’t account for overlooked ITC and ITR filings, penalties and interest from late filings, or those late nights in March: these hidden costs lower the break-even point even further.

Three events almost always push you past the threshold all at once: a volume exceeding 100 transactions per month, your first hire (payroll and source deductions), and incorporation (T2 and CO-17). If any of these three is on the horizon, plan to delegate the work beforehand, not afterward.

The limits of doing it yourself: Five signs it’s time to hand it over

The method described above works as long as the situation remains straightforward. Here are the red flags that most frequently come up in inquiries received by Bankeo when a business owner decides to outsource:

• Your entry is more than a month overdue. The routine has broken down; every additional week brings the case closer to a catch-up fee at the high end of the range.
• You’re Hiring. Payroll, source deductions, payments to the CRA and Revenu Québec, T4 forms, and RL-1 slips: payroll is the area where improvising costs the most.
• You’re incorporating a business. T2 and CO-17 returns and a company’s financial statements can’t be cobbled together using a spreadsheet; this is the classic time to turn to an accountant.
• Are you looking for financing? A lender wants accurate financial statements, and sometimes a review engagement by a CPA; inaccurate books slow down the process.
• The GST and QST are stressing you out. Delayed filings, taxes collected and spent, notice of assessment: this is the most urgent warning sign, because interest is accruing.

Does this sound like you? We’ve broken down these triggers in Signs It’s Time to Hire an Accountant, and if you’re unsure which plan to choose, compare the Cost of a CPA vs. a bookkeeper. Many entrepreneurs actually opt for a hybrid approach: they handle day-to-day data entry themselves and outsource account reconciliation, taxes, and year-end closing.

Frequently asked questions

Is it legal to do your own bookkeeping in Quebec?

Yes. There is no law requiring a business to hire a professional to handle its bookkeeping. Your obligations focus on the end result: reliable records, supporting documents retained for six years, GST and QST returns filed on time with Revenu Québec, and accurate tax payments. Only the certification of financial statements (audit or review), when required by a lender or business partner, must be performed by a CPA regulated by the Ordre des CPA du Québec.

How long does it take to do your own bookkeeping?

Allow 2 to 4 hours per month for about 25 monthly transactions: a weekly routine of 30 to 45 minutes, a monthly reconciliation, tax filings based on your frequency, and a few hours of year-end closing. The time required increases rapidly with higher transaction volume, payroll, and multiple sales platforms: once you exceed about 100 transactions per month, you almost always cross the threshold where outsourcing becomes cost-effective.

At what point does outsourcing become cost-effective?

When the value of your time exceeds the cost of outsourcing. The median accounting budget for a Quebec SME is approximately $3,000 per year, or about $250 per month, based on actual fees from 1,248 contracts concluded through Bankeo (2024-2026), out of more than 15,000 requests received. At $50 per hour, the break-even point drops to about 5 hours of bookkeeping per month; at $100 per hour, to about 2 hours and 30 minutes. The breakdown by sector is in the Bankeo Fee Barometer.

Should you start with a spreadsheet or accounting software?

A well-structured spreadsheet is sufficient for about 25 transactions per month, provided you maintain weekly discipline. Switch to online accounting software as soon as your transaction volume increases, you file GST and QST regularly, or you have employees: bank connectivity, pre-programmed rates, and automatic reports reduce errors and data entry time. The key indicator: the day manual data entry starts holding you back, switch Tools or delegate.

Do I need to register for the GST and QST to keep my books?

Registration is not tied to bookkeeping, but to your sales: it becomes mandatory when your taxable supplies exceed $30,000 over four consecutive calendar quarters; below that threshold, you are considered a small supplier, and registration remains optional. In Quebec, registration and filing of GST/QST returns are handled through Revenu Québec, which administers both taxes. Once registered, keep the taxes collected separate and claim your ITCs and your ITRs.

Is bankeo’s service really free?

Yes. Bankeo is completely free for entrepreneurs, with no obligation. The accountants in our network pay a fee per file, and the amount is known in advance. You’ll never receive an invoice from Bankeo, and if the match no longer works out, even months later, we’ll connect you with another accountant at no cost: we’re always here to support you.
