Invoicing & sales tax, in brief
If you freelance in Canada, your invoice usually needs to show the right sales tax for your province: either GST, or the combined HST in participating provinces (and sometimes a separate provincial PST/QST). The rate depends on where the supply is made, and it changes by province — so a generic template can quietly get it wrong. The invoice generator above pulls the correct GST/HST rate per province and shows the math so you can check it.
Most small businesses must register for GST/HST once they stop being a “small supplier” — broadly, once worldwide taxable revenues pass $30,000 over four consecutive calendar quarters. The exact rules and current rates live on the CRA site; always confirm there before you rely on a figure. See GST/HST for businesses (canada.ca).
FAQ
Do these tools cost anything or need an account?
No. They’re free and need no signup. Each tool runs entirely in your browser — nothing you type is sent to a server.
Is the GST/HST math correct for my province?
Both the invoice generator and the GST/HST calculator apply the current GST/HST rate for the province you select and show the breakdown. Provincial rates are verified against canada.ca at build time and cited on each tool. As with anything tax-related, confirm against the official source if it’s material.
Can I reverse GST/HST out of a tax-included total?
Yes — the GST/HST calculator has a “remove tax” mode: enter a tax-included total and it shows the pre-tax amount and the GST/HST that was inside it (for example, $113 in Ontario is $100 plus $13 HST).
Can I get a PDF of my invoice?
Yes — the invoice generator produces a clean, printable invoice you can save as a PDF directly from your browser. No upload, no watermark.
