How much is the salary of external security guards? Do I have to declare tax?

It depends on who is paid. If it is paid to individual security personnel, it should be included in the subject of "management fee-salary" and declare personal income tax (if it does not exceed 2,000 yuan, it will be declared zero, and if it exceeds 2,000 yuan, it will be withheld and remitted); If it is paid to a security company, it depends on the setting of the secondary account under "management fee" in your company's accounting subjects, such as "management fee-labor fee", which is not in the "management fee-salary" account. Your company does not need to declare personal income tax, which is withheld and remitted by the security company.
