(1) The non resident tax rate is set to rise to 24.75% from the current 24% level. That doesn't sound much but it comes on top of the reintroduction of the wealth tax and a big crackdown on holiday home owners who neglect to pay their taxes (see our guide What to do if you get a letter from the Spanish tax office)
(2) IBI or local property taxes are also set to rise across the country by an average of €30 for each of the next two years as the government seeks to let local councils raise about another €1 billion in taxes. It is supposed to be a temporary measure.
Older properties that haven't been revalued for 10 years will be the worst hit as the tax will go up 10%
If you want to see whether you will get off lightly or suffer then take a look at your last IBI bill and look for the "ano rev" or year of revaluation - if it is 2002 or prior it will be a 10% rise, 2002-6 6%, 2009 or later 4%. Properties revalued between 2007-8 will see no increase as they were the peak property bubble years and the properties are overvalued any way.
