Around 8,500 families in Fife claiming working tax credits are hoping for a reprisal from Chancellor George Osbourne.
Pressure is growing on the Chancellor to scrap plans to cut tax credits.
SNP MSP Clare Adamson says even leading Tory figures including Boris Johnston and Scottish Leader Ruth Davidson have spoken against the cuts.
Last month the House of Lords rejected the plans.
Clare Adamson MSP says:
"The SNP has consistently opposed damaging Tory cuts to Tax Credits. Just as pressure is growing on the Chancellor to reverse this callous reduction in support for low income families, now is not the time to let-up on our opposition to the Tories.
"From the outset SNP MPs at Westminster have voted against the changes and have lodged amendments to the Scotland Bill to devolve Tax Credits in full. And the SNP government has committed to bringing forward credible and costed plans to support low income households if the cuts do go ahead.
"This week we have seen another two well respected think-tanks line up to offer George Osborne alternative approaches that will reduce the impact of the cuts – alternatives that wouldn’t even break the Chancellor’s self-imposed austerity targets."
