How Iowa’s Legislative Funnel Works

Every Iowa legislative session, hundreds of bills are introduced, but only a fraction become law. One of the main reasons is the funnel: a pair of deadlines that decide which bills remain eligible for debate.

What is the funnel?

By the first funnel deadline, most bills must be approved by a full committee in the chamber where they were introduced. By the second funnel deadline, bills that have passed one chamber must be approved by a committee in the other chamber. In 2026, for example, the first funnel deadline was Feb. 19 and the second was March 20.

Which bills are exempt?

Not every bill is subject to the funnel. Bills dealing with appropriations, taxes and government oversight, as well as bills introduced by legislative leaders, are exempt. That is why significant policy can still surface late in the session, sometimes in budget or tax bills.

What happens to bills that miss the funnel?

Bills that miss a funnel deadline are generally considered dead for the session, but dead is not always gone. Lawmakers can revive ideas by attaching them as amendments to bills that are still eligible, by placing bills on the unfinished business calendar, or through exempt leadership bills on the same subject.

Why the funnel matters for your organization

• Timing is everything. If you want a bill to move, it needs a sponsor, a subcommittee and a committee vote within the first several weeks of session.

• Problem bills can come back. A bill that died in the funnel can return as an amendment or in an exempt bill, so monitoring has to continue through the end of session.

• Exempt bills deserve attention. Appropriations, tax and oversight bills can carry policy changes late in the session.
