As is typical throughout the tax year, some states change their tax rates and their apportionment ratios and methods. Calendar and fiscal taxpayers alike are affected by the changes. And based on where your particular entity may be in its processes, you could be extending your returns, preparing or finalizing your returns, completing year end or quarterly tax provisions, or already into your quarterly estimates for 2019. The following is a summary of the majority of changes.
