1. You do not have the general taxpayer qualifications, VAT invoices you have no way to obtain.
2. No need for any tax on behalf of the opening, just ask the other side to open on the line
4. If the other side of the equipment is bought before 2009, itself purchased without credit, then, he sold you can be halved at a rate of 4% tax rate, rather than 17%, which is the tax incentives, then your purchase price will be much lower. For example, the equipment does not include tax 1 million, the normal situation, the tax 170,000, a **** 1.17 million. If you halve it at 4%, then it's only 20,000 in taxes, a **** 1.02 million.
In short, it is called the other party to open the ordinary VAT invoice to you, and issued at 4% halved rate, the price can be lowered again.
