The time limit to compensate the negative tax bases of the company tax in Spain generated by the losses from previous tax years has changed drastically by the law 27/2014.
New measures are being taken in the law 27/2014: compensation of negative tax bases:
How compensation of negative tax bases is being dealt with, is set forth in article 26 of the law 27/2014 and this now changes substantially. These tax bases will be applied without any time limit in the future. In other words, negative tax bases generated since 1997 may be compensated from now onwards. Congratulations!
There is however a quantity limit of 70% of the tax base prior to compensation. But then again, a compensation of 100% is allowed in case the minimum amount is 1 million euros.
