If Plaid Cymru holds the balance of power following the general election, the party has said it will demand that Wales is funded to the same level per head as Scotland and have the same taxation rights, according to the party’s manifesto
The funding pledge would see Wales benefit by around £1.2bn a year.
Plaid Cymru also plans to reintroduce the 50p income tax rate for all those earning more than £150,000 as well as increasing the upper earnings limit on National Insurance contributions to £100,000 a year.
The party wants to end pensions relief for higher rate taxpayers and double the bankers' levy.
It would transfer control of corporation tax to Wales, and reduce the VAT rate for house renovations and the tourism industry. It is committed to introducing the living wage, rather than the National Minimum Wage, for all employees by 2020.
In addition, Plaid Cymru says it will crack down on tax avoidance with plans to reverse what it says were 25% cuts in staffing at HMRC which started under the previous Labour government.
It would introduce a financial transactions tax, in line with the levy proposed by the EU, as well as new taxes such as a tax on sugary drinks which the party says would be used to fund medical services.
