Quick answer: the date that anchors most of the schedule is 9 months from death, when both the Inventory and the inheritance tax return come due together. See the full Pennsylvania probate timeline calculator for your specific estimate.
The core deadlines, in order
| Deadline | Pennsylvania rule | Statute |
|---|---|---|
| DHS notice (if decedent received Medicaid) | Within 3 months of grant of Letters | 20 Pa.C.S. § 3162 |
| Notice to creditors published | Promptly; starts the 1-year claim clock | 20 Pa.C.S. § 3162 |
| Inventory due | Within 9 months of death | 20 Pa.C.S. § 3301 |
| Inheritance tax return due | Within 9 months of death (5% discount if paid within 3) | PA Dept. of Revenue |
| Creditor claim period | 1 year from first publication | 20 Pa.C.S. § 3532 |
| Audit/objection notice | At least 20 days before | Pa. O.C. Rule 2.5(c) |
No direct notice to creditors required
The 1-year period is about distribution timing, not just a claim bar
Under § 3532, a creditor who misses the 1-year window doesn't automatically lose their claim — they can still recover from estate assets that haven't yet been distributed. If the personal representative distributes assets within that year, or after receiving a claim, and the estate later can't cover a valid claim, the personal representative can be personally liable. This makes the 1-year mark less a hard deadline and more the point at which it becomes safer to distribute.
