President Emmanuel Macron's promise of new tax cuts in France could create further tension between Italy's anti-establishment government and the European Union, analysts told CNBC. In an attempt to stop months of ongoing protests at home, Macron announced Thursday income tax cuts totaling 5 billion euros ($5.6 billion). He also said that worker bonuses of up to 1,000 euros wouldn't be taxed; single parents would get extra support; and no schools or hospitals would be closed until 2022. These new measures are expected to increase the country's fiscal deficit further and breach the European Union's rules once again. Analysts at Berenberg Bank estimate that France's fiscal deficit will reach 3.2% this year, even excluding these latest measures. European rules state that member nations should not surpass a deficit threshold of 3%.

Double standards?

"That is as sure as eggs is eggs. The Italian government has done it before and will do it again," Florian Hense, economist at Berenberg told CNBC when asked if Rome is likely to use the French situation to accuse Brussels of double standards. Italy has been at odds with the European Commission, the EU's executive arm, over spending since the current anti-establishment government took power in June last year. The executive in Rome increased public spending — something that Brussels criticized and tried to curb, arguing that Italy was disrespecting the EU's fiscal rules. In this battle over extra spending, the Italian government has accused Brussels of treating different countries in different ways. This is because France has breached fiscal rules on several occasions without receiving serious punishment, such as a fine, from the EU.

Italy's Deputy Prime Minister Matteo Salvini said in December that the Commission must treat Italy and France in the same way regarding their spending plans. However, the Brussels-based institution made it clear that the fiscal situations in Italy and France are different and require different approaches. Whereas in Paris, Macron is still presiding over a reform agenda, Rome has shown little desire to improve the structural foundations of the Italian economy. At the same time, Italy has the second highest pile of public debt in the euro zone at about 130% of GDP (gross domestic product). "This is the perfect story for Salvini. It gives him more flexibility," Claus Vistesen, economist at Pantheon Macroeconomics, told CNBC over the phone about the latest French policies. He argued that Macron's measures give more power to Salvini and other Italian politicians to argue in favor of their country's fiscal expansion.
