With a North American (Canadian provincial and U.S. state) sales tax
With a 10% sales tax:
The manufacturer pays $1.00 for the raw materials, certifying it is not a final consumer.
The manufacturer charges the retailer $1.20, checking that the retailer is not a consumer, leaving the same profit of $0.20.
The retailer charges the consumer $1.65 ($1.50 + $1.50x10%) and pays the government $0.15, leaving the same profit of $0.30.
So the consumer has paid 10% ($0.15) extra, compared to the no taxation scheme, and the government has collected this amount in taxation. The retailers have not lost anything directly to the tax, and retailers have the extra paperwork to do so that they correctly pass on to the government the sales tax they collect. Suppliers and manufacturers have the administrative burden of supplying correct certifications, and checking that their customers (retailers) aren't consumers.
With a value added tax
With a 10% VAT:
The manufacturer pays $1.10 ($1 + $1x10%) for the raw materials, and the seller of the raw materials pays the government $0.10.
The manufacturer charges the retailer $1.32 ($1.20 + $1.20x10%) and pays the government $0.02 ($0.12 minus $0.10), leaving the same profit of $0.20.
The retailer charges the consumer $1.65 ($1.50 + $1.50x10%) and pays the government $0.03 ($0.15 minus $0.12), leaving the profit of $0.30 (1.65-1.32-.03).
So the consumer has paid 10% ($0.15) extra, compared to the no taxation scheme, and the government has collected this amount in taxation. The businesses have not lost anything directly to the tax. They do not need to request certifications from purchasers who are not end users, but they do have the extra accounting to do so that they correctly pass on to the government the difference between what they collect in VAT (output VAT, an 11th of their income) and what they spend in VAT (input VAT, an 11th of their expenditure).
