Before this course: Self-Employed Tax Concepts: records, deductions and instalments (course 5.8.2). You should already know how to keep an audit trail, sort current and capital costs, and plan for instalments. This course goes one level up: the taxes a business collects for the government, the taxes it handles as an employer, and how a corporation changes the picture.
How a value-added sales tax really works
Imagine a lemonade stand that buys lemons and sells lemonade. Each time money changes hands, a little tax is added. The stand keeps a list: tax it collected from customers and tax it paid to the lemon seller. It sends the government only the difference. The customer at the end pays the tax; the stand is the collector.
- Many countries use a value-added style of sales tax. Canada calls it GST/HST; the Philippines, China and South Korea call it VAT; Japan calls it consumption tax. The United States has no national sales tax; states and cities set their own (see the box).
- In Canada, a GST/HST registrant recovers the GST/HST paid on business purchases and expenses by claiming input tax credits (ITCs) (CRA).
- Net tax (CRA, regular method): add up the GST/HST you collected or that became collectible, subtract the ITCs you can claim; "the difference between these two amounts, including any adjustments, is your net tax."
- If net tax is positive, you remit (pay) it with the return. If it is negative (more credits than tax collected), the return shows a refund claimed (line 114 in the CRA instructions).
- ITCs can be claimed only for purchases used in commercial activities, the expense must be reasonable, and you need proper documents before you claim. New registrants can generally claim ITCs only for the period after they registered.
- Time limit (CRA): most registrants must claim ITCs by the due date of the return for the last reporting period that ends within four years.
- Zero-rated supplies (such as basic groceries in Canada) are taxable at 0%. Some other supplies are exempt. The two are not the same thing; the CRA treats them differently, so check each product or service.
| Step | Amount |
|---|---|
| Sales before tax | 1,000 |
| Tax collected from customers (10%) | 100 |
| Business purchases before tax | 400 |
| Tax paid on those purchases (10%) | 40 |
| Net tax = 100 - 40 | 60 to remit |
The 10% rate is made up for practice. Real rates are in the box below.
- Federal GST is 5%. In HST provinces the federal and provincial parts are combined: Ontario HST 13% (5% federal + 8% provincial); Nova Scotia HST 14% since 2025-04-01. Manitoba charges GST 5% plus its own PST 7%. Quebec has its own QST. Use the CRA calculator for other provinces.

- There is no national sales tax or VAT. Sales tax is set by states, and many cities and counties add their own. Rates and what is taxed differ by place and by type of good. Some states have no statewide general sales tax.

- The national tax is Value-Added Tax (VAT). The standard rate is 12% of the gross selling price of goods (NIRC Section 106, as amended by RA 10963).

- Draw a chain of three boxes: Supplier, Your business, Customer.
- Write the tax amount on each arrow (tax paid to the supplier, tax collected from the customer).
- Fill in the example table with your own practice numbers and a 10% rate.
- Subtract: tax collected minus tax paid on purchases.
- Write "remit" if the answer is positive and "refund" if it is negative.
- Look up the real name and standard rate of the sales tax in your country in the box.
- Check: you can explain in one sentence why the business is a collector, not the final payer.

I'm learning "Small Business Tax Concepts: GST/HST, payroll and incorporation" on The Future Market. Lesson 1: "How a value-added sales tax really works". What the lesson teaches: - Many countries use a value-added style of sales tax. Canada calls it GST/HST; the Philippines, China and South Korea call it VAT; Japan calls it consumption tax. The United States has no national sales tax; states and cities set their own (see the box). - In Canada, a GST/HST registrant recovers the GST/HST paid on business purchases and expenses by claiming input tax credits (ITCs) (CRA). - Net tax (CRA, regular method): add up the GST/HST you collected or that became collectible, subtract the ITCs you can claim; "the difference between these two amounts, including any adjustments, is your net tax." - If net tax is positive, you remit (pay) it with the return. If it is negative (more credits than tax collected), the return shows a refund claimed (line 114 in the CRA instructions). - ITCs can be claimed only for purchases used in commercial activities, the expense must be reasonable, and you need proper documents before you claim. New registrants can generally claim ITCs only for the period after they registered. - Time limit (CRA): most registrants must claim ITCs by the due date of the return for the last reporting period that ends within four years. - Zero-rated supplies (such as basic groceries in Canada) are taxable at 0%. Some other supplies are exempt. The two are not the same thing; the CRA treats them differently, so check each product or service. The exercise I'm working on: Make up one month for a small business: three sales and two purchases. Use a 10% practice rate. Work out tax collected, tax paid, and net tax. Then redo it with your country's real standard rate from the box. I'm stuck. Please: 1. Explain the main idea in plain, simple words with one everyday example. 2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step. 3. Don't just give me the final answer. Help me do it myself, and check my work when I share it. 4. This is for learning only. Remind me to check with a licensed professional before I make a real decision about my own money, health or legal situation.
I'm a parent helping my child (about 8 years old) with a lesson called "How a value-added sales tax really works" from the course "Small Business Tax Concepts: GST/HST, payroll and incorporation". Here's what the lesson says: Imagine a lemonade stand that buys lemons and sells lemonade. Each time money changes hands, a little tax is added. The stand keeps a list: tax it collected from customers and tax it paid to the lemon seller. It sends the government only the difference. The customer at the end pays the tax; the stand is the collector. The activity: Make up one month for a small business: three sales and two purchases. Use a 10% practice rate. Work out tax collected, tax paid, and net tax. Then redo it with your country's real standard rate from the box. Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words. Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time. Keep it general and educational. This is not advice for a real situation.

Quiz
In a value-added sales tax, who is the business mainly acting as?
A collector: it collects tax on sales and sends the government the difference after credits.
How is net sales tax worked out under the regular method?
Tax collected on sales minus credits for tax paid on business purchases.
What happens if the credits are bigger than the tax collected?
The return can show a refund.
Why should a growing business track sales over several quarters?
Many countries require sales tax registration once sales pass a set line, so you need to know when you cross it.
Why does a supplier's tax registration number on an invoice matter?
Tax paid to a supplier that is not properly registered may not be claimable as a credit.
What decides whether a worker is an employee or a contractor?
The real facts of the working relationship, such as control, tools, risk and chance of profit, not just the label.
What three things does an employer do with payroll taxes?
Withholds from the worker's pay, adds the employer share, and sends it all to the government on time.
Where should an employer get the right payroll amounts for each pay?
From the tax agency's own tables or calculator.
What is the key legal difference between a sole proprietorship and a corporation?
A corporation is a separate legal person, so it owns its debts and assets; a sole proprietor is personally responsible.
Does a corporation file its own tax return?
Yes, it files its own return (in Canada, a T2 every year, even with no tax payable), separate from the owner's.
What are the two main ways an owner can be paid from a corporation?
A salary through payroll, or dividends from after-tax profit.
Why put every tax stream on one calendar?
A small business can have several due dates for sales tax, payroll and returns, and one calendar helps you not miss any.
