Who really pays
Philadelphia charges every home the same 1.40% of its assessed value. Abatements and exemptions shrink what some homes are taxed on — here's this block:
- 407 S 23rd Sttax-abated new construction1.04%$9,207/yr on $885K
- 410 S 23rd Stexemption1.22%$9,640/yr on $789K
- 414 S 23rd Stexemption1.25%$11,660/yr on $933K
- 416 S 23rd Stexemption1.25%$11,758/yr on $940K
- 406 S 23rd Stexemption1.25%$11,898/yr on $950K
The starkest example: 407 S 23rd St is assessed at $885K but pays $9,207 a year — about 74% of the $12,388 it would owe at the full rate, because its new-construction value is abated for 10 years.
