General tax law topics will clearly give whether the price includes tax, but some things need our own judgment, which are summarized as follows:

1. The sales amount on the special VAT invoice must be tax-free;

2. Out-of-price expenses and overdue package deposit must include tax;

3. "Retail" and the amount on the check must include tax;

4. The sales amount on the ordinary invoice must include tax;

5. The total price tax must include tax (tautology, hehe);

6. Unless otherwise specified, the actual price of trade-in is tax-inclusive.

7. Unless otherwise specified, the price of selling second-hand goods includes tax.

8. The general taxpayer's non-retail transaction price is tax-free without other tips.

9. The amount of goods in the construction and installation contract includes tax.

10. The price of out-of-price expenses includes taxes.

1 1. The package deposit includes tax (in fact, the package deposit itself is an out-of-price fee);

12. The price sold to small-scale taxpayers includes tax.
