以下是一个用Python编写的个税计算程序：
def calculate_tax(income):
tax = 0
if income <= 5000:
return tax
income -= 5000
if income <= 3000:
tax = 0.03 * income
elif income <= 12000:
tax = 0.1 * income - 210
elif income <= 25000:
tax = 0.2 * income - 1410
elif income <= 35000:
tax = 0.25 * income - 2660
elif income <= 55000:
tax = 0.3 * income - 4410
elif income <= 80000:
tax = 0.35 * income - 7160
else:
tax = 0.45 * income - 15160
return tax
income = float(input("请输入您的收入："))
tax = calculate_tax(income)
print("应缴纳的个人所得税为：", tax)
请注意，此程序仅适用于中国的个税计算标准，具体计算方法可能因地区和个人情况而异。若有需要，请根据实际情况进行相应修改。
