个人所得税计算器python

以下是一个简单的个人所得税计算器 Python 代码：

def calculate_tax(income):
    if income <= 5000:
        tax = 0
    elif 5000 < income <= 8000:
        tax = (income - 5000) * 0.03
    elif 8000 < income <= 17000:
        tax = (income - 8000) * 0.1 + 90
    elif 17000 < income <= 30000:
        tax = (income - 17000) * 0.2 + 990
    elif 30000 < income <= 40000:
        tax = (income - 30000) * 0.25 + 3590
    elif 40000 < income <= 60000:
        tax = (income - 40000) * 0.3 + 6090
    elif 60000 < income <= 85000:
        tax = (income - 60000) * 0.35 + 12090
    else:
        tax = (income - 85000) * 0.45 + 20840
    return tax

income = float(input("请输入您的税前收入："))
tax = calculate_tax(income)
print("您的应纳税额为：{:.2f}元".format(tax))

使用方法：

1. 运行代码后，会提示输入税前收入；
2. 输入税前收入，按回车键确认；
3. 程序会计算个人所得税并输出结果。
