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))
