On November 15, 2006, the government eliminated the excise tax of 6.6% on imports (taxes on cigarettes, liquor, and cars are still in effect) and substituted it for a 5.5% islandwide Sales and Use Tax, plus a municipal sales tax of 1.5%, for a total of 7%, in what has been known as the Puerto Rico Tax Reform. This change was partly due to the government's growing expenditures and fiscal deficits which remained unchecked and uncorrected for several years, until several credit agencies warned public officials that all general-obligation bonds issued by the government were to be downgraded if the problem was not corrected.
