The Ulster Unionist Party has said tax reductions and extra money for mental health will be part of its price for joining any coalition government.
The party will seek VAT rate cuts for property repairs and the hospitality industry.
However, it insisted there would be no "begging bowl" approach to negotiations during a hung parliament.
Leader Mike Nesbitt said he would be prepared to work with the Conservatives or Labour.
However, he ruled out supporting the SNP if it was intent on another independence referendum in Scotland.
Main pledges
Reducing economic dependence on the rest of the UK through a drop in corporation tax and generating greater wealth while balancing the budget at Stormont's devolved assembly were among other priorities outlined.
Mr Nesbitt said he wanted to concentrate on winning seats before deciding his position on a Westminster coalition.
He added: "We will do our best for the people of Northern Ireland, but our values are not an auction item.
"We will not take short-term advantage if it means long-term damage to the Union and to our children, and grandchildren and future generations.
"So, no begging bowl approach from us, come May 8."
He refused to speculate on whether Labour or the Conservatives would be preferable partners and said the best solution for stability was a clear majority.
He added: "I cannot see circumstances in which we would want to be associated with the SNP because we have had a referendum on independence, the people of Scotland have voted to stay in the UK and it is clear the SNP don't accept that vote.
"I imagine that might be an insurmountable obstacle to doing business with the SNP."
Mr Nesbitt said the Troubles legacy still lingered for victims and support was needed from Westminster to tackle that.
