The full House and Senate will return to the Capitol on Wednesday.
The session is scheduled to end Wednesday, so lawmakers will have to vote to extend their working time when they return.
Budget bills must be passed no later than five days before the end of a session, so Friday would've been the last day for action without an extension.
The fiscal year begins July 1.
If lawmakers don't extend the regular session, Republican Gov. Haley Barbour will have to call a special session and he'll control the agenda. Republican Lt. Gov. Phil Bryant says he is "not offended by that prospect."
