Personal income tax rate:

After the reform, the original business tax was changed to value-added tax, and the value-added tax increased by 6% (modern service industry) and 1 1% (transportation industry).

According to the experience of Shanghai pilot project, the tax burden of enterprises has been reduced after the reform. Business tax is calculated and paid according to the full amount of income. After changing to value-added tax, some costs can be deducted, which can actually reduce the tax burden.

Due to the introduction of VAT deduction, compared with the full collection of the original business tax, the tax burden will be reduced or even greatly reduced; For 85,000 small-scale taxpayers, after the business tax is changed to value-added tax, the collection rate is 3%, which is 2 percentage points lower than the original business tax rate. There is indeed an increase in the tax burden of individual enterprises in the reform.

Comprehensive income (income from wages and salaries, income from labor remuneration, and income from royalties) is subject to a 7-level progressive tax rate, and tax is calculated according to the monthly taxable income. The tax rate is divided into seven levels according to the taxable income of individual monthly wages and salaries, with the highest level being 45% and the lowest level being 3%.

Proportional tax rate. Personal income tax is levied on personal income such as interest, dividends, bonus income, property lease income, property transfer income, accidental income and other income, and the proportional tax rate of 20% is applicable.

According to the actual tax burden of business tax in the pilot industries, the VAT rate of land transportation, water transportation, air transportation and other transportation industries is basically between 1 1%- 15%, and the modern service industries such as R&D and technical services, information technology, cultural creativity, logistics assistance and forensic consulting services are basically between 6%-/kloc-0.

In order to keep the overall tax burden of the pilot industries from increasing, two low tax rates, 1 1% and 6%, are selected for the pilot reform, which are applicable to the transportation industry and some modern service industries respectively.

The advertising agency industry belongs to the scope of changing business tax into value-added tax, and the tax rate is 6%.
