I would have thought that all sales tax plans would have a way to credit back producers for intermediate products, or else you get all kinds of distortions in pricing, depending on the exact mix of labor, number of steps in construction, etc.
For instance, if I had a product that went through a chain of five intermediates who each added 10% value to something, I’d wind up with this:
First producer buys product for $10. Pays 10% tax.
He adds 10% in value. Sells it to the next guy for $12.10. Next guy pays $1.21 in tax. He adds 10% in value, and sells it to the next guy for $14.50. That guy pays $1.45 in tax. Now we’re already up to $15.95, and the government has collected over 20% in taxes already. On the other hand, a company that buys the material for $10, does all the value-added work in-house, and sells it for $15 pays less than half the tax on the same product. This simply doesn’t make sense. There can’t be a tax system in effect today that does this, can there?
I thought with a VAT, only the end sale to the customer was taxed, and businesses got a business exemption. That’s effectively the same thing as a National Sales Tax, isn’t it? Am I missing a distinction somewere?
In Canada, businesses don’t pay GST. It works like this:
I buy a software product from a wholesaler for $100. I pay 7% GST on it.
I sell software for $150. I charge 7% GST.
I then take the $10.50 in GST I collected from the sale, subtract the $7.00 in GST I paid to the vendor, and send the government $3.50. But I can also deduct the GST I paid for other expenses operating my business. There were plenty of times when my GST return to the government was zero, because the GST I paid out for all my business expenses exceeded the GST I collected from customers.
The other way you could do things would be to give businesses a tax exemption number. Under that system, when the wholesaler sells me the software, I give him my tax exemption number and he doesn’t charge me a sales tax at all. That’s roughly the same thing (assuming the tax rate was adjusted to make it revenue neutral), but it would be more of a pain to administer, I’d think.
