The Italian government has approved an amendment to the contentious tax on business aircraft that it made law on April 29. Now, foreign-registered aircraft operated privately will incur the tax only if they stay for 45 consecutive days, rather than the 48-hour threshold in effect until now. The amendment, which is expected to be endorsed by the Italian parliament, would also reduce the rate of the tax by 50 percent.
