1.TDS will calculate based on employee total income for the financial year of the employees, If the employee joins mid of the year then tax will calculate and deduct for the remaining month in the financial year. In gerytHR, we have a provision to update the previous employment income so tax will adjust automatically based on the previous employment income and current income and deduct the tax accordingly.
2.Employee has to submit previous employment income, If the employee didn’t submit previous employer income in such case, if an employee falls under tax bracket then the tax will calculate and deduct based on the current salary, otherwise, it will not deduct. The employee may face an issue at the time of filing IT returns in case of a shortfall deduction in tax.
