Answer:
St. Peter’s Church.
Step-by-step explanation:
According to the passage given, it is evident to say that the property belongs and belonged to St. Peter's Church. And it is only proper to imply that the tax is paid by the very same.
The property that is listed in the passage is about an estate belonging to the Westminster's St. Peter's Church. It has a "meadow, [...] woodland [...] and 25 houses [rented by] abbot's knights and other men who pay 8 shillings a year". And the passage also includes the worth of the estate as 12 pounds during the reign of King Edward. Owned by the church, it is only possible that it also pays the taxes for the said property.
