Why this is more than a tax calculator
GST/HST searches often begin with rate math, but the real business decision is price, margin, and cash control. A page that separates collected tax from spendable revenue is more valuable than a short rate calculator.
Classification before calculation
The calculator should not pretend to decide place of supply or registration status. The page should tell readers to confirm treatment first, then use the selected rate to calculate invoice totals and tax cash.
Margin after tax
A Canadian seller can collect the right tax and still underprice the sale after card fees, shipping, marketplace costs, refunds, software, and labour. Linking tax and margin calculators makes the page more useful.
Decision Checklist
- Confirm place of supply and applicable rate before calculating.
- Separate GST/HST collected from net revenue.
- Check PST or provincial requirements where relevant.
- Calculate margin after shipping, fees, and returns.
- Reserve remittance cash before treating revenue as spendable.
Practical FAQs
Can the calculator decide my GST/HST rate?
No. The user chooses the rate after checking official treatment. The calculator handles the arithmetic once the rate is known.
Why include a margin calculator?
Because tax compliance does not guarantee profitability. Small businesses also need to know whether the transaction remains profitable after costs.
