This kind of situation is also called no contact, which is caused by the internal comparison of the tax system. The tax bureau will ask you to provide some information, and your tax will be passed on to the tax bureau of the other unit, and the tax bureau of the other unit will find the seller to handle it.

At this time, your tax bureau will let you transfer out the input tax, and the tax bureau of the other company will inform you of the tax after handling it, and your tax bureau will inform you of the deduction.

We all operate like this here, I hope to give you reference.
