There is no fixed date. The Senate Appropriations Committee releases each bill's text when it marks the bill up, and it posts the accompanying project lists, called congressionally directed spending tables, on its official site as the bills move. In recent cycles the Senate has released bills in waves: a few in early summer, then a rush in the weeks before a recess or a funding deadline.
What actually gets released
When the Senate committee acts on a bill, three documents matter. The bill text itself. The committee report explaining it. And the congressionally directed spending table, the list of every project the bill funds, with the amount, the recipient, the location, and the senators who requested it. The tables are the documents everyone searches the moment they appear, because they answer "what did my town get."
Where things stand right now
The live position of every FY2027 bill in both chambers is on the tracker, verified against official sources and updated several times a day. The calendar lists every posted markup. As of this writing the House has released project lists for its bills, and those projects are already searchable by state on the earmarks map.
What happens here the day the Senate posts
When the Senate's FY2027 tables appear, Approps loads every project into the state by state map and the by bill ledgers, each record carrying its amount, recipient, city, requesting senators, and a link to the official table it came from. That is the same treatment the FY2026 tables and the House FY2027 lists already have: more than 15,000 records, every one sourced.
How to watch for it
The committee posts to appropriations.senate.gov. Approps checks the committee's pages several times a day, and the tracker moves the moment a markup result or floor action is verified. If you want the short version of how the whole process works, it is on the process page.
