Engineering needs to issue a unified invoice for construction and installation. This kind of invoice is based on the principle of territorial management, and where to construct it, it must be invoiced locally, so the other party must provide you with the Jian 'an invoice from the local tax bureau where your company is located, and pay the business tax and surcharges for engineering construction in your local area.

You are the owner and the other party is the construction party. You have no obligation to withhold and pay taxes. You can ask the other party to apply to the local taxation bureau for issuing Jian 'an invoices and paying taxes. If the other party refuses, you can also withhold and pay taxes. After all, if the other party does not pay taxes, the local taxation bureau will eventually find trouble with your company. Therefore, you can also go to the local taxation bureau to declare your taxes and ask for invoices. You need to provide the construction contract, the copy of the business license and tax registration certificate of the other party, and the proof of the other party's business activities. The business tax rate of Jian 'an invoices is 3%, and the urban construction tax and education surcharge are levied on the basis of business tax. Usually, the urban construction tax is 7%, and the education surcharge is 3%, that is, the business tax and surcharge comprehensive tax rate is about 3.3%.
