# Expiring Budget Authority Ledger: free sample (Tensorust LLC)

490 federal accounts holding $193B of unobligated money that expires Sep 30, 2027, plus the accounts that just lapsed on Sep 30, 2026.

**Headline:** Every Treasury Account Symbol (TAS) whose budget authority stops being available for new obligations on Sep 30, 2027 (490 accounts, $193B unobligated as of Aug 31, 2026) or that lapsed on Sep 30, 2026 ($515B was still unobligated with one month left).

This repository is a **free teaser**, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has **1,382 rows** and is sold by Tensorust LLC: **[https://tensorust.com/datasets/expiring-appropriations/](https://tensorust.com/datasets/expiring-appropriations/)**.

## Method and limits

Download File A for FY2026 P11 at the TAS level, keep fixed-period accounts ending 2026 or 2027 with an unobligated balance above zero, and compute share unobligated.

Not a forecast of contract awards. Part of an unobligated balance may be reserved, apportioned for later, or legally unavailable. No-year accounts are excluded. Expired money can still pay for adjustments to existing obligations for five years.
