python123个人所得税计算器

以下是一个简单的Python个人所得税计算器，根据用户输入的工资金额和社保费用计算应纳税额：

def calculate_tax(salary, insurance):
    # 计算应纳税所得额
    taxable_income = salary - insurance - 3500
    # 根据应纳税所得额计算税率和速算扣除数
    if taxable_income <= 0:
        tax_rate, quick_subtractor = 0, 0
    elif taxable_income <= 1500:
        tax_rate, quick_subtractor = 0.03, 0
    elif taxable_income <= 4500:
        tax_rate, quick_subtractor = 0.1, 105
    elif taxable_income <= 9000:
        tax_rate, quick_subtractor = 0.2, 555
    elif taxable_income <= 35000:
        tax_rate, quick_subtractor = 0.25, 1005
    elif taxable_income <= 55000:
        tax_rate, quick_subtractor = 0.3, 2755
    elif taxable_income <= 80000:
        tax_rate, quick_subtractor = 0.35, 5505
    else:
        tax_rate, quick_subtractor = 0.45, 13505
    # 计算应纳税额
    tax = taxable_income * tax_rate - quick_subtractor
    # 计算税后工资
    after_tax_salary = salary - insurance - tax
    # 返回结果
    return '{:.2f}'.format(after_tax_salary)

# 测试代码
salary = float(input('请输入工资金额：'))
insurance = float(input('请输入社保费用：'))
print('税后工资为：', calculate_tax(salary, insurance))
