python计算个人所得税代码

以下是一个简单的Python计算个人所得税的代码，根据用户输入的工资金额进行计算：

def calculate_tax(income):
    # 应纳税所得额 = 工资金额 － 各项社会保险费 - 起征点(3500元)
    taxable_income = income - 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 = 0
        quick_deduction = 0
    elif taxable_income <= 1500:
        tax_rate = 0.03
        quick_deduction = 0
    elif taxable_income <= 4500:
        tax_rate = 0.1
        quick_deduction = 105
    elif taxable_income <= 9000:
        tax_rate = 0.2
        quick_deduction = 555
    elif taxable_income <= 35000:
        tax_rate = 0.25
        quick_deduction = 1005
    elif taxable_income <= 55000:
        tax_rate = 0.3
        quick_deduction = 2755
    elif taxable_income <= 80000:
        tax_rate = 0.35
        quick_deduction = 5505
    else:
        tax_rate = 0.45
        quick_deduction = 13505
    # 应纳税额 = 应纳税所得额 × 税率 － 速算扣除数
    tax = taxable_income * tax_rate - quick_deduction
    return max(0, tax)  # 税额不能为负数

income = float(input("请输入您的工资金额："))
tax = calculate_tax(income)
print("您的个人所得税金额为：{:.2f}元".format(tax))
