In addition, and subject to EU clearance, two sectors of the economy only were to pay a new tax on profit. The sectors were financial services providers and utility companies.

Since the taxes were to be capped at 15%, local companies which used to pay 20% or 35% profits tax would have been better off, while 'offshore' companies would be worse off only if they employed staff or occupy premises locally. Many companies, particularly those used to hold Spanish property interests, do neither.

In March, 2003, the EU's Council of Finance Ministers confirmed that the reforms did not constitute harmful tax measures. However, in April, 2004, the Commission argued that the new rules would give companies domiciled in Gibraltar an unfair advantage over their counterparts in the UK, under a principle known as 'regional selectivity'. The Commission also took issue with the fact that since the taxes were based on payroll and the occupation of business premises, offshore companies registered in Gibraltar would be unlikely to incur any tax liability. The EC therefore rejected the reforms, effectively suggesting that for taxation purposes, Gibraltar should be considered part of the United Kingdom.

Gibraltar dissolved its qualifying companies tax regime in January, 2005, as negotiations continued in Brussels. In a move that cost the Gibraltar government an estimated £1.5 million in annual tax revenues, the remaining qualifying companies, of which there were about 80, switched to the ‘exempt’ companies regime. “Each qualifying company has been dealt with on an individual basis and alternative arrangements made,” Caruana added.

Later that month, it was announced that Gibraltar had been given until 2010 (2007 for new companies) to phase out its exempt company tax regime after the European Commission ruled that the scheme violated EU state aid rules.

Major changes to Gibraltar's corporate tax regime were announced in Chief Minister Peter Caruana's June 2007 Budget speech.

Mr Caruana explained that:

"The Tax Exempt Company has been the backbone of the development and growth of both our finance centre and the online gambling industry, and thus of a very significant part of our economy. It continues to underpin thousands of jobs in Gibraltar and large amounts of Government revenue."

"In order to comply with EU law we must phase out the tax exempt company in 2010. However, in order to sustain our successful economic model we must retain a commitment to a very competitive corporate tax model."

Since it is no longer legally acceptable to have one tax model for ‘local’ companies and a different one for ‘foreign’ companies it is necessary to have a low tax system for all companies because
without a low tax system for overseas companies they will leave, and our economy
will suffer hugely. Thousands of jobs would be lost, as well as significant Government revenue. I have therefore already said, and I reaffirm now, that the Gibraltar Government is irrevocably committed to the principle of ‘low tax’ for our economic operators."

"By mid-2010 the Government will have introduced an across the board flat, low corporate tax rate. This will most probably be set at 10%, but in any event not higher than 12%. This will be similar to arrangements that already exist in Ireland, Cyprus, Malta and other EU Countries."

"In the intervening period, the Government will engage in an intensive, detailed and lengthy process of consultation with the different economic sectors."

"In order to signal the Government’s seriousness of purpose in this respect I am today taking the first step in the process of reducing corporate tax rates in Gibraltar, by 2% for the year of assessment 07/08 from 35% to 33%, and with effect from the year of assessment 2008/09 by a further 3% from 33% to 30%."

" I would also signal the intention of a further reduction the year after that to 27%, in anticipation of the introduction of the flat low tax rate in 2010."

In December 2008, the European Court of First Instance ruled in favour of Gibraltar, stating that the European Commission was wrong to argue that the tax reforms proposed in 2002/03 were in breach of state aid rules, and effectively giving the jurisdiction licence to set its own tax rules.

The Court dismissed the EU Commission’s case, and stated that although the UK is representative of Gibraltar, Gibraltar does, however, have fiscal autonomy from the UK, and therefore can introduce its own individual tax system (the aforementioned 10-12% corporation tax).

In a statement to the press at the time, Peter Caruana, Gibraltar's Chief Minister, said he was "overjoyed" by the outcome.

"The Court has found in Gibraltar’s favour and has accepted our arguments on each and every issue, relating both to regional selectivity and material selectivity, and has ordered the commission to pay the Gibraltar government’s legal costs.”

“This needs to be clearly understood. Had Gibraltar lost the Regional Selectivity case, we would have had to adopt the UK’s company tax system and company tax rates. That would result in the bulk, if not all, of the finance centre and gambling companies leaving Gibraltar. That would have meant the loss of thousands of jobs throughout our economy, and a very large fall in government revenue. This in turn would have rendered unsustainable our current level of public services and public sector employment.”

“This is a huge and vital victory for Gibraltar. A threat to our economic, social, and thus political well-being, has, once again, been successfully seen off. I believe that the economy of Gibraltar now has the opportunity to forge ahead to the next level of growth and development, to fulfil its great potential and thus to guarantee that we shall bequeath economic and social prosperity and stability to our children, grand children and future generations. “

”Once again, this small community has demonstrated that, when right is on our side, and we hold our nerve and we behave reasonably and intelligently, we have the ability and determination to defend our rights and interests as a people, even when they are challenged by more powerful entities and forces.”

”On behalf of the people of Gibraltar, I wish to thank all those companies in the financial services and gambling sectors and other sectors of the economy that have had the faith and confidence in us to stay with Gibraltar during these difficult and uncertain times.”

“The threat that Gibraltar has faced cannot be understated, nor therefore, can the importance of this victory to Gibraltar and its people and our future.”

In his budget in June 2008, Peter Caruana announced his intention to bring forward a 3% cut in corporate tax originally scheduled to take place in 2009, meaning that the corporate rate would drop by 6% that year.

"Last year, and in order to signal the Government’s seriousness of purpose in reducing corporate tax rates, I reduced corporate tax rates to 33%, and said that I would reduce it further this year to 30%, with a signalled reduction to 27% next year," Caruana told Parliament in his budget speech.

"In order to further signal the Government’s commitment I am advancing that timetable by one year, and therefore the corporate tax rate is now reduced by 6% from 33% to 27% with effect from this year that is the year of assessment 2008/09," he added.

Caruana explained that he envisaged a further cut in the rate next year, before moving to the rate of between 10% and 12% from 2010, adding that: "My strong preference will favour the bottom end of that range."
