Hello, poster
The 6 tax rate you are talking about is the tax rate for the business tax-to-VAT reform, which is the original business tax.
If you do not have input deductions, it is equivalent to one tax point more than the previous business tax.
Both special tickets and general tickets can be opened at 6, depending on the needs of your customers.
It is necessary to go to the tax bureau to increase the tax type, because your software production is a new tax type, which is completely different from before. It is recommended to go to the national tax, it is not a troublesome thing.
Hope your career goes well~
