Prepaid tax = (total price and out-of-price expenses-subcontracts paid) ÷( 1+9%)×2%, and 3% is simply charged in advance.

Prepayment time: At present, most electronic tax bureaus can handle it. Enterprises from other provinces and cities need to log in to e-tax as a natural person if they want to register for inspection and declaration in advance after arriving at the place of business. Through the electronic tax bureau, they can relate and bind cross-regional reports of other provinces. Return to the report on cross-regional affairs of foreign management certificates in other provinces, and click the prepayment declaration. Or use the prepayment function of the electronic tax bureau.

When you come back to declare, fill in the prepaid figures in Schedule 4. If it is necessary to deduct, the main table is prepaid in installments and Schedule 4, and the deduction will be made in this period.
