While supporters of the bill believe it will help middle class working families the religious leaders say it will hurt Maine's poorest residents.
They are calling on senator Susan Collins to vote against the current tax bill.
Chair of the social justice committee Suzanne Kelly said "I've been very impressed in the past with how she has thoughtfully looked at all of the aspects of these very difficult bills, and she has I think voted her conscience and done in most cases whats good for the people of Maine."
Reverend Rebecca Liberty said "It doesn't serve the common good to concentrate more wealth in the hands of the wealthiest one percent and corporations and instead of helping vulnerable populations it actually hurts them for a variety of reasons."
Earlier today senator Collins said she was not committed to voting for the senate tax bill citing concerns over health care and the loss of a deduction for state and local taxes.
