Individuals and couples benefit from personal allowances which reduce their liability to tax and which increase in line with the number of dependent children.A new structure has been created for the taxation of income, which now falls into two categories: the general base and the savings base of income.The general base includes salary and other benefits from employment, income from economic activities, and property rental income (either actual or deemed). Such income is reduced by applicable deductions and allowances. It is subject to a progressive scale which is applied to successive portions of taxable income with rates ranging from 24% to 43%. In the autumn of 2011 a new tax bracket was introduced for higher income earners as an austerity measure, with income over €175,000 now subject to a 45% rate.The savings base is subject to a 19% tax rate on savings income up to €6000 and to 21% on the excess and includes interest, dividends, and capital gains/losses paid to residents in Spain, together with life and disability insurance proceeds paid to Spanish residents by a Spanish entity (or an EU insurer operating on a Freedom of Services passport into Spain) where any investment element is limited to Spanish tax compliant funds.Some Autonomous Communities have considered increasing the local personal income tax rates to help combat the economic crisis in Spain. The following maximum rates for personal income tax have been agreed for the 2011 tax year e.g. Andalucia: 48%; Asturias: 48.5%; Cataluna: 49%.
