Yes. The preferential treatment that lets you tax a one-off annual bonus separately from comprehensive income has been extended through 31 December 2027. You choose the method when filing.
Usually the separate method wins when your salary is already in a mid or high bracket. If your annual income after deductions is low, folding the bonus into comprehensive income can use up unused low-rate brackets and cost less.
No. Only the employee’s own social insurance and housing fund contributions reduce taxable income. Employer contributions are not part of your taxable wages.
