New employee join my company on October with Monthly Salary - 6000 but why system show zero amount on Tax amount when generate payroll?

Personal Income Tax is calculate by Total Income of the year, it's not calculate by Monthly Income. So have that employee worked with other company on January - September?

1) Go to Employees > Employees > Click on Past Tax.

2) Click on Employee Code that want to key in Past Tax.

After keyin Past Tax then system will based on actual total income of that employee for this year and calculate the tax amount for deduction.

Answer: No. This employee have no working from January to September so he/she have no income for that and total income on Oct is no Tax require.
