The business of 20 19 will be invoiced in 2020. How will the differential tax be invoiced? What will happen?

20 19 business, and no invoice was issued at that time. In 2020, the invoice difference will be taxed, and only ordinary invoices can be opened at first. For tourism services, you can choose the total price and extra-price fees obtained, and deduct the balance of accommodation fees, catering fees, transportation fees, visa fees, ticket fees and travel expenses paid by the buyers of tourism services to other tourism companies.

Taxpayers enter tax-included sales (or tax-included assessment amount) and deduction amount through the differential tax invoicing function in the invoicing system. The system automatically calculates the tax amount and tax-excluding amount, and the words "differential tax" are automatically printed in the remarks column. Invoicing should not be confused with other taxable activities.
