Legislators will talk next week about passing a stop-gap budget that will allow the state to function past June 30 if there's no big budget agreement by then.
House Speaker Thom Tillis raised the possibility of a continuing resolution, or a CR, on Thursday.
The House and Senate passed $20.6 billion budgets, but they differ significantly in some details. And, the legislature cannot pass a budget before members agree on a new tax code.
"The tax reform numbers have implications for the budget," said Rep. Nelson Dollar, a Cary Republican and House budget writer.
A CR is "more likely than not," he said.
CRs are a bit of a flash back to the days when Democrats ran the legislature and the state had a Democratic governor.
Last session, Republicans took pride in passing budgets not just on time, but ahead of schedule, as they overrode Democratic Gov. Bev Perdue's vetoes.
After session, Tillis and Rep. David Lewis, a tax negotiator, spent a good amount of time Thursday afternoon meeting with the Senate Republican caucus.
Senate Leader Phil Berger said the tax negotiations "are moving."
