Updated Checked by the Tax-Services.ca editorial team How we check
Nobody can name the best accounting software for every Canadian small business, because the right pick depends on your sales tax setup, your staff and how many invoices you send. What you can do is run a few tests, and the first one is whether the product handles GST/HST correctly for your province.
What should your accounting software track?
Before you compare anything, write down four things: your province, if you’re registered for GST/HST, if you have employees, and how many invoices go out each month. Those answers decide which features you need, and they’ll save you from paying for a pile of extras you’ll never open. A freelancer with ten clients needs invoicing and expense capture. A shop with staff needs payroll and source deduction reports on top.
The Canada Revenue Agency says you must keep accounting and financial records in an organized way, on paper or in electronic form. Its electronic record keeping guidance covers backups and acceptable formats. So ask any vendor how you’d get your data out if you left.
How do you test the sales tax settings?
Sales tax varies by province, and the software has to apply the right rate to every sale. Try a $1,000 sale in Ontario, which the GST and HST calculator handles. HST is 13%, or $130, so the customer pays $1,130.00.
Do the same thing in any trial: create an invoice, look at the tax line, then open the sales tax report. Sell in more than one province? Test a sale to each one, because a product can get Ontario right and stumble on the rest. If a price already includes tax, the HST reverse calculator gives you the pre-tax figure to check against the software.
| Yearly taxable supplies | Usual GST/HST reporting period |
|---|---|
| $1.5 million or less | Annual, with the option to file quarterly or monthly |
| More than $1.5 million and under $6 million | Quarterly, with the option to file monthly |
| More than $6 million | Monthly |
Make sure the product can produce a return summary for your period. Monthly and quarterly filers owe the return and payment one month after the period ends.
What about payroll and source deductions?
Hire someone and the picture changes. Take one Ontario employee paid $3,000 a month. The payroll remittance calculator shows $732.02 going to the CRA each month: $502.42 held back from the employee and $229.61 you add as the employer. The month’s full payroll cost is $3,229.61.
Does the software work those amounts out, or is payroll a paid add-on? Set up a test employee and compare its numbers with the calculator. Employers in Quebec also deal with Revenu Quebec, so ask about that if it’s you.
Which mistakes cost people the most?
- Choosing on price alone. We couldn’t confirm current prices, plan limits or free tiers for any named product, so read each vendor’s page on the day you buy.
- Skipping the trial. Test invoicing, tax and reports with real examples.
- Leaving out your accountant. Ask which formats theirs can read, and whether they can log in directly.
- Forgetting the exit. You’ll need your records for years, so confirm you can export them.
- Trusting rankings. A list of the best product can’t see your situation.
Once the books are running, the profit margin calculator turns your sales and costs into margins. Then test your yearly profit in the corporate tax calculator.
Where the numbers come from
Reporting period thresholds and record keeping rules are from Canada Revenue Agency pages read on 30 September 2026. Calculator examples use the 2026 rates and limits in our tools. No product is recommended here, and this site has no link with any government body or software vendor.
Frequently asked questions
What should Canadian accounting software handle?
GST/HST at the right provincial rate, sales tax reports, invoicing and expense tracking. Add payroll if you have staff.
How often will I file GST/HST?
Usually once a year up to $1.5 million of taxable supplies. Between $1.5 million and $6 million it's quarterly, and above that monthly.
Can I keep my records in electronic form?
Yes. The CRA allows electronic records and has guidance on backups and formats, so ask a vendor how you can export data.
Is free software enough for a sole proprietor?
It can be when you only need invoices and expenses. Check what the plan includes for tax reports and payroll before you rely on it.
How can I test the tax in a trial?
Create a $1,000 invoice for your province and compare the tax line with a calculator. In Ontario, HST should be $130.
