税率表, 2018.10新个税

tax_ratio = OrderedDict()
tax_ratio[(0, 5000)] = 0
tax_ratio[(5000, 3000)] = 0.03
tax_ratio[(3000, 12000)] = 0.1
tax_ratio[(12000, 25000)] = 0.2
tax_ratio[(25000, 35000)] = 0.25
tax_ratio[(35000, 55000)] = 0.3
tax_ratio[(55000, 80000)] = 0.35
tax_ratio[(80000, float(‘inf’))] = 0.45

计算税

def tax(income, social_benefits=0):
income -= social_benefits
total_tax = 0
for k, v in tax_ratio.items():
if income > k[1]:
income -= k[1]
total_tax += k[1] * v
elif k[0] < income < k[1]:
total_tax += income * v
break
return total_tax

if name == ‘main’:

print(tax(social_benefits=2295, income=15000))
