The US taxation service in Florida provides important information about tax filing deadlines for individuals and businesses. For individuals, the filing deadline is April 15th of each year. Businesses have the option of filing on the 15th day of the 4th month after the end of their tax year. For example, if a business ends its tax year in December, its filing deadline will be April 15th. It's important to note that businesses can request an extension of time to file, but any taxes due must be paid by the original filing deadline.
