The Pennsylvania Archives(see the "Pennsylvania Genealogy" section of this site), 3rd series, volumes 11-22, contains tax lists for varying years between 1765 and 1791, for 14 of the 19 counties created by 1788. Indexes are in volumes 27-29 of the series FHL films 824436-37

The Family History Library has microfilm copies of many county tax lists from county or state repositories. These lists often date from the creation of the county and to the early 1800s. An example is Pennsylvania, Comptroller General, Tax and Exoneration Lists, 1762-1801 FHL film 295759 (first of 29 films).
