The Senate approved extending an earned-income tax credit for the working poor and allocating revenue from utility taxes to municipal governments.
It was also expected to vote on a proposal to raise the income tax for millionaires in order to provide property tax relief.
All three have already passed in the Assembly and all could face Christie's veto.
Christie also has to decide by Saturday whether to use his line-item veto powers on the nearly $32 billion budget adopted along party-line votes early this week.
