I am not sure what I am missing here.

class Product: _price = 0.0 tax_rate = 0.12

def __init__(self, base_price):
    self._price = base_price

@property
def price(self):
    return self._price + (self._price * self.tax_rate)

@price.setter
def price(self, price):
    _price = price
product.py
class Product:
    _price = 0.0
    tax_rate = 0.12

    def __init__(self, base_price):
        self._price = base_price

    @property
    def price(self):
        return self._price + (self._price * self.tax_rate)

    @price.setter
    def price(self, price):
        Product._price = price

You're really close! But when referring to instance attributes, where you are currently using the class name use "self" instead.
