Wages and salaries refer to all cash or non-cash labor remuneration paid by an enterprise to employees held or employed in the enterprise in each tax year, including basic salary, bonuses, allowances, subsidies, year-end salary increase, overtime pay and other expenses related to employees' holding or employment. Science and technology innovation award should also be one of the bonuses.
Article 4 of the Individual Income Tax Law of People's Republic of China (PRC) stipulates that the science and technology bonuses awarded by various ministries and commissions in the State Council are tax-free, so if the science and technology innovation award you won is national, and State Taxation Administration of The People's Republic of China has issued a document to exempt this bonus from tax, then you are exempt from personal income tax.
